Defender’s steel entry doors are manufactured using 22-gauge steel, making them 30% to 60% stronger than most doors on the market (which typically use 24 or 26-gauge steel). Our doors feature:

• All-steel construction including steel edges (not wood edges that can crack)
• 40 Security rating—the highest in the industry
• Polyurethane foam insulation with an outstanding R-Value of 15.1
• Magnetic weatherstripping (refrigerator technology)
• Adjustable threshold for airtight seal
• Zinc galvanized, primed, painted, and baked finish for durability
• Guaranteed not to warp, rust, or swell for as long as you own them

All Defender steel entry doors have an R-Value of 15.1, providing outstanding energy efficiency. The polystyrene core insulation combined with magnetic weatherstripping and an adjustable threshold creates an airtight seal—just like a refrigerator—making our doors perfect for Chicago’s extreme climate.

Yes! We offer IronWood™ paintable/stainable doors with a deep wood grain look in true panel and rail design. These doors can be:

• Painted to create the grain look of a wood door in any of our color selections
• Hand-stained to create the beauty of wood without the maintenance
• Stained on one side and painted on the other for ultimate flexibility

All IronWood stained doors receive the exclusive GuardCoat™ finish for years of uncompromised beauty. Even though they’re steel, they look just like real wood!

We offer many Sherwin Williams® Acrylic Enamel baked-on finishes. You can even choose different colors for the inside and outside of your door for ultimate color coordination. Contact us to see our full color selection and samples.

Magnetic weatherstripping uses refrigerator technology to create a durable, airtight seal around your door. This provides year-round comfort by preventing drafts, increasing energy efficiency, and keeping the elements out—especially important in Chicago’s harsh climate with extreme temperature swings.

Absolutely! Decorative glass used in all Defender doors creates artistry in light with hand-soldered caming, precision-cut bevels, and a wide variety of styles. Each piece is unique due to the random nature of swirls and other effects—aesthetic variations are not defects but the essence of hand-crafted glass. All glass units are cradled in high-performance frames guaranteed not to split, crack, or warp.

The Ultra-Frame is Defender’s exclusive 18-gauge steel replacement frame that offers superior security and durability. Key features include:

• Allows installation directly inside existing jamb without disturbing exterior trim
• Exclusive aluminum stop design (won’t rot, warp, crack, or blister like wood)
• Nested hinge pocket for ultimate strength
• Thermally efficient adjustable sill
• T-strike and deadbolt strike nested into 18-gauge solid steel for maximum security
• Painted to match door exterior
• Complete with magnetic weatherstrip

We offer extensive hardware choices including:

• Standard locks (included with every door)
• Super security locks
• Schlage locks
• Keyless entry systems
• Lever-style handles
• Various finishes: bright brass, antique brass, antique nickel, brushed nickel, oil-rubbed bronze, and more
• Optional door knockers
• Mail and magazine slots
• Kickplates
• Decorative or spring hinges

Yes! Defender steel entry doors are specifically designed to handle Chicago’s extreme weather conditions including:

• Temperature swings of over 100 degrees (summer to winter)
• Heavy snow and ice
• Strong winds
• High humidity in summer

Our magnetic weatherstripping, adjustable threshold, R-Value of 15.1 insulation, and steel construction ensure your door performs perfectly year-round regardless of Chicago’s weather.

All Defender doors feature a full 4″ x 10″ composite lock block that has more screw-holding power than wood. It’s injection molded for uniform size, preventing distortion of the door skin that typically occurs with wood lock blocks. This provides superior hardware mounting and long-term reliability.

Yes! We can install steel entry doors with sidelites (side panels with glass) for added light and visual appeal. Check out our gallery for examples of entry door and sidelite installations.

Yes! We offer custom-sized doors for non-standard openings. However, we’ll always look for ways to save you money—sometimes we can cut into a header to make an underheight opening accommodate a standard size door, saving you the custom-size upcharge.

Yes! We specialize in round top entry and storm doors for unique architectural styles. These custom doors add distinctive character while maintaining the same quality and security features as our standard doors.

Defender steel entry doors provide superior security through:

• 22-gauge steel construction (30-60% stronger than standard doors)
• All-steel edges that won’t crack or split like wood
• Composite lock blocks with superior screw-holding power
• 40 Security rating (highest in the industry)
• Optional super security locks and deadbolts
• Ultra-Frame system with nested strike plates in solid steel
• Reinforced hinge systems

This combination makes forced entry extremely difficult, protecting your family and possessions.

Our 22-gauge steel doors are extremely durable and resistant to denting. The heavy-gauge steel we use is significantly thicker and stronger than typical doors. Combined with the polyurethane foam core, Defender doors are built to withstand impacts that would damage lighter doors.

Yes! If you choose a painted finish, you can repaint your door in the future if you want to change colors. The baked-on finish provides an excellent base for repainting. If you choose a wood grain stained finish, those can be refinished as well.

Defender’s security storm doors are crafted from 16-gauge steel (not soft aluminum like many competitors). Key features include:

• 16-gauge steel frame that matches the strength of the door
• Locks engage from 16-gauge steel into 16-gauge steel frame for maximum security
• Over 60 unique styles including decorative wrought iron designs
• Mitered corners welded at 45° angles covering 30% more surface area
• Vault pins for maximum hinge security
• Powder-coated, baked-on finishes for lasting color
• All-season ready with complete installation

Vault pins are steel pins that lock into the hinge-side frame. Even if someone removes the hinges from the outside, the door remains secure as long as the deadbolt is locked. This provides an additional layer of security that prevents forced entry.

Every Defender security storm door features corners welded at a 45° angle (mitered) to cover 30% more surface area than standard corners. This design ensures added strength and prevents premature deterioration, keeping your door looking great and functioning properly for years.

We offer over 60 unique styles of security storm doors, including decorative wrought iron designs. With a wide range of colors available, you can find the perfect look to match your home’s aesthetic while maximizing security.

We offer a wide range of powder-coated, baked-on finish colors that ensure vibrant, lasting color with minimal maintenance. Contact us to see our full color selection and find the perfect match for your home.

We never cut corners by using soft aluminum frames. Steel provides significantly more strength and security than aluminum. Our 16-gauge steel construction means your locks engage from steel into steel, creating a much more secure system that resists forced entry and stands up to Chicago’s weather conditions.

Every Defender security storm door includes complete all-season installation with:

• Glass and screens (both!)
• Knob/lever and deadbolt
• Pneumatic closer (for controlled closing)
• Weatherstripping
• Door sweep
• Wind chain
• Expander with sweep
• All closing hardware
• FREE professional installation by our experienced team

Yes! We offer patio security storm doors specifically designed for sliding patio doors. These provide added security and energy efficiency for your patio entrance.

Absolutely! Security storm doors create an additional barrier against the elements, helping to:

• Reduce drafts
• Improve insulation
• Lower heating and cooling costs
• Protect your main door from weather damage
• Allow ventilation while keeping insects out (with screens)

This is especially valuable in Chicago’s climate with extreme seasonal temperature changes.

Yes! Defender security storm doors come with both glass and screen panels that can be switched seasonally. Use the screen for ventilation during warmer months and the glass panel for insulation during colder months.

Our storm doors are designed for easy seasonal changes. During your installation, we’ll show you exactly how to switch between the glass and screen panels. It’s a simple process that most homeowners can do in just a few minutes.

Yes! A security storm door acts as a protective barrier for your main entry door, shielding it from:

• Direct sunlight (prevents fading and deterioration)
• Rain, snow, and ice
• Wind-driven debris
• Temperature extremes

This protection extends the life of your entry door and maintains its appearance.

In most cases, yes! Our experienced installers will assess your entry door and opening during the consultation to ensure proper fit and function. We can work with virtually all standard entry door configurations.

• Create a stunning architectural feature
• Maximize natural light
• Provide panoramic views
• Add interior space and depth
• Dramatically enhance curb appeal
• Can include a window seat area

We’ve transformed many Chicago homes with beautiful bow window installations!

Quality vinyl replacement windows like those from Defender typically last 20-40 years or more with minimal maintenance. Factors affecting longevity include:

• Quality of materials and installation
• Exposure to extreme weather
• Regular cleaning and care
• Proper operation (not forcing stuck windows)

Our lifetime warranty on windows ensures your investment is protected.

Yes! Window replacement is one of the top home improvements for return on investment. New windows:

We’ll discuss the specific process for your home during the consultation.

In most cases, yes! We offer a wide variety of window styles, grids, and configurations. Bring photos or measurements to your consultation and we’ll work to match your existing windows or help you choose a complementary style for your home.

We carefully select window manufacturers known for quality, durability, and performance. During your consultation, we’ll show you our window options and explain the features and benefits of each. We stand behind every window we install with our lifetime warranty.

Yes! Screens are included with applicable window styles to allow for ventilation while keeping insects out.

Vinyl windows are very low maintenance:

• Clean glass with standard glass cleaner
• Wipe vinyl frames with mild soap and water
• Clean tracks and sills regularly to prevent dirt buildup
• Lubricate moving parts annually with silicone spray
• Check weatherstripping and seals periodically

We’ll provide complete care instructions at installation.

Absolutely! With over 40 years of experience in Chicago, we’ve installed thousands of windows in brick homes. Our experienced installers know how to work with brick, stone, and all types of construction while maintaining structural integrity and aesthetic appeal.

Condensation on the exterior or interior surface of windows is normal and indicates your windows are preventing heat transfer. However, condensation between the panes indicates seal failure and requires window replacement. Our windows feature superior seals to prevent this issue.

Yes! Every Defender door and window purchase includes FREE professional installation. This is a significant value—big box stores typically charge $200-$500 or more for door installation. Our experienced team (not subcontractors) handles every installation with expert craftsmanship.

Most door installations are completed in a single day. During your consultation, we’ll provide a specific timeline based on your project’s requirements and complexity.

Window installation time depends on the number of windows and complexity of the project. A typical single window replacement takes 1-2 hours. Multiple window projects may take a full day or be scheduled over multiple days. We’ll provide a specific timeline during your consultation.

Yes, we recommend being home during installation so you can review the work, ask questions, and provide access to all necessary areas. We’ll also conduct a final walkthrough with you to ensure complete satisfaction.

We handle all necessary carpentry work as part of your installation. Whether it’s repairing damage, addressing rot, adjusting the rough opening, or making modifications to accommodate your preferred size, we’ll include this in your quote and complete it professionally.

Absolutely! We regularly work with non-standard openings and can either:

• Provide a custom-sized door or window to fit your opening
• Modify the opening to accommodate a standard size (often saving you money)

Our experienced installers will assess your situation and recommend the best solution.

We have over 40 years of experience working with all types of Chicago homes, including older brick and stone construction. Our experienced installers know how to work with the unique challenges these homes present while maintaining their architectural integrity.

Yes! Our installation service includes removal of your old doors and windows and proper disposal of all debris. We leave your home clean and ready to enjoy your new products.

Our experienced installers take great care to protect your existing finishes. When using our Ultra-Frame system for doors, we can often install directly inside the existing jamb without disturbing exterior trim. Any necessary carpentry work is completed professionally and cleanly.

Yes! We offer aluminum trim coil (also called capping) for exterior finishing. This protects your installation from the elements and provides a polished, professional appearance. We also offer interior trim options including ranch or colonial casing for doors.

Minimal preparation is needed! We recommend:

• Clear the area around doors/windows (move furniture, decorations)
• Remove window treatments if possible
• Provide clear access for our installers

We provide comprehensive warranty coverage:

• Lifetime warranty on all door and window products
• One-year warranty on parts and labor
• Doors guaranteed not to warp, rust, or swell for as long as you own them

This is significantly better coverage than big box store installations and demonstrates our confidence in both our products and our installation quality.

Our lifetime product warranty covers manufacturing defects and structural issues with the doors and windows themselves. Defender doors are guaranteed not to warp, rust, or swell for as long as you own your home. Windows are warranted against seal failure, hardware malfunction, and material defects.

For one year after installation, we warranty both the parts and the labor. If any issues arise with your installation or any components during this time, we’ll repair or replace them at no charge. This covers installation-related issues and ensures everything functions perfectly.

We provide service and warranty support for all Defender-installed doors and windows. If you experience any issues with products we’ve installed, we’ll take care of them under our warranty coverage. However, we do not repair doors or windows installed by other companies or purchased elsewhere.

Simply contact Defender at 708-780-7320 if you experience any issues with your door or window. We’ll promptly address your concerns and make any necessary repairs covered under warranty.

While labor is covered for one year, the lifetime product warranty continues to protect you. If a product defect or issue arises after the first year, the parts are still covered under our lifetime warranty. We’ll work with you to address any concerns and can provide service as needed.

We keep records of all installations and warranties automatically. However, we recommend keeping your paperwork in a safe place for your records. Contact us if you need warranty documentation.

Big box stores can advertise lower prices because they buy in huge volume, but there are significant differences:

Big Box Store Doors:

Energy savings vary based on:

• Condition of existing doors/windows
• Number of products replaced
• Size of your home
• Your heating/cooling system
• Temperature settings
• Current insulation levels

Many Chicago homeowners see 15-30% reductions in heating and cooling costs after replacing drafty old doors and windows with energy-efficient Defender products. The R-Value 15.1 insulation in our doors and multi-pane glass in our windows significantly reduces heat transfer.

R-Value measures resistance to heat flow—the higher the number, the better the insulating properties. Our steel entry doors have an outstanding R-Value of 15.1, which means they provide excellent insulation against Chicago’s extreme temperatures, keeping your home comfortable and reducing energy costs.

Absolutely! Drafts are one of the most common reasons homeowners replace doors and windows. Our products feature:

• Doors: Magnetic weatherstripping, adjustable thresholds, and airtight seals
• Windows: Weathertight seals, multi-pane construction, and precision fitting

These features virtually eliminate drafts, dramatically improving home comfort.

Yes! Both our doors and windows provide excellent sound insulation:

• Steel doors with polyurethane cores block sound transmission
• Multi-pane windows with gas fills between panes reduce noise
• Weathertight seals prevent sound infiltration

This is especially valuable for Chicago homes near busy streets, airports, or other noise sources.

Yes! Our windows can be equipped with Low-E (low-emissivity) coatings that block harmful UV rays while allowing visible light to pass through. This significantly reduces fading of furniture, flooring, artwork, and window treatments while also improving energy efficiency.

Yes! Our products contribute to environmental sustainability through:

• Energy efficiency – reduces fossil fuel consumption
• Durability – long lifespan means less waste
• Recyclable materials – vinyl and steel are recyclable
• Low maintenance – no harmful chemical treatments needed
• Made to last – quality construction reduces replacement frequency

Plus, lower energy consumption reduces your carbon footprint.

Low-E (low-emissivity) glass has a microscopically thin coating that reflects heat while allowing light to pass through. This means:

• In winter: Heat stays inside your home
• In summer: Heat stays outside your home
• Year-round: UV protection prevents fading
• Result: Lower energy bills and more comfortable home

Our windows can be equipped with Low-E coatings for maximum energy efficiency.

Both argon and krypton are inert gases used between window panes to improve insulation:

• Argon – Most common, excellent performance, cost-effective
• Krypton – Superior insulation, more expensive, best for thin spaces

Both are better insulators than air and don’t conduct heat as readily, improving window energy efficiency.

We use 16-gauge steel for our security storm doors—both the door and the frame. This is significantly stronger than the aluminum used by many competitors. 16-gauge steel provides maximum security and durability.

A traditional screen door only has a screen panel for ventilation. A storm door includes both:

• Glass panel for insulation in cold weather
• Screen panel for ventilation in warm weather
• Interchangeable panels for seasonal use

Our security storm doors are heavy-duty versions made with 16-gauge steel for maximum security and durability, with both glass and screen included.

A pneumatic closer (also called a door closer) is a mechanism that automatically and gently closes your storm door at a controlled speed. This prevents the door from slamming, protects the frame, and ensures the door closes securely. All Defender storm doors include pneumatic closers.

Weatherstripping is material installed around doors and windows to seal gaps and prevent air infiltration. Our entry doors feature magnetic weatherstripping (like a refrigerator door) that creates an airtight seal. This prevents drafts, improves energy efficiency, and keeps out dust, insects, and moisture.

The threshold is the bottom piece of a door frame. An adjustable threshold can be raised or lowered to create a perfect seal with the door bottom, preventing drafts and water infiltration. As your home settles over time, the threshold can be adjusted to maintain the seal. All Defender entry doors include adjustable thresholds.

A pre-hung door comes already mounted in a frame (jamb) with hinges attached. This ensures proper alignment and makes installation more efficient and reliable. Most of our doors can be installed either as pre-hung units or with our Ultra-Frame steel frame system.

Capping (also called aluminum trim coil) is aluminum material wrapped around the exterior door or window frame for finishing. It:

• Protects wood from weather damage
• Eliminates the need for painting
• Provides a clean, finished appearance
• Extends the life of the installation
• Comes in colors to match your products

We offer capping as part of our trim package options.

All Defender entry doors include a peephole installed during manufacturing, so you don’t need to add one later. If you want to upgrade or change the peephole style, contact us for options.

A sidelite (or sidelight) is a vertical window panel installed beside an entry door. Sidelites:

• Add natural light to your entryway
• Create an elegant, welcoming appearance
• Make your entry feel more spacious
• Can feature decorative glass
• Often installed in pairs (one on each side)

We can install entry doors with sidelites for added beauty and light.

These are two common interior trim styles:

• Colonial casing – Traditional style with decorative profile and edges
• Ranch casing – Simpler, more contemporary flat profile

Both provide a finished look around your door. We offer both styles to match your home’s aesthetic.

With proper care, Defender products should last decades:

• Steel Entry Doors – 30+ years (guaranteed not to warp, rust, or swell)
• Security Storm Doors – 20-30+ years with minimal maintenance
• Vinyl Windows – 20-40+ years

Our lifetime warranty ensures your investment is protected. Many original Defender installations from decades ago are still performing beautifully today.

Some frost accumulation between the storm door and entry door is normal during extreme cold, especially if there’s a significant temperature difference. This actually indicates your storm door is doing its job—creating a buffer zone that protects your entry door. The frost will dissipate when temperatures moderate.

You can! Many homeowners use just the screen panel during summer for ventilation while the main entry door is open. This allows air flow while keeping insects out. Our pneumatic closer ensures the storm door closes gently even in windy conditions.

Don’t worry about measurements before calling! During your free consultation, our experienced team will take precise measurements of your openings. We’ll determine whether standard sizes work or if custom sizing is needed, and we’ll look for ways to save you money (like modifying the opening to fit a standard size if possible).

Changes may be possible depending on the manufacturing stage of your order. Contact us immediately if you want to make changes. Custom orders that have already been manufactured cannot be changed, which is why we take care during the consultation to ensure you’re completely satisfied with your selections.

We offer numerous hardware finishes (bright brass, antique brass, antique nickel, brushed nickel, oil-rubbed bronze, etc.) so you can match existing hardware in your home. Bring a sample or photo to your consultation and we’ll match it as closely as possible.

We take great care to minimize disruption:

• We protect your floors and work areas
• We work efficiently to complete installation quickly
• We contain dust and debris
• We remove all old materials
• We clean up thoroughly before we leave
• Most installations complete in a day

You can typically resume normal activities immediately after we finish.

Minimal preparation is needed:

• Clear area around doors/windows (furniture, decorations, plants)
• Remove window treatments if possible
• Provide clear pathway for installers and materials
• Secure pets in a separate area
• Plan for someone to be home
• Remove items from window sills

We’ll provide specific instructions when scheduling your installation.

We monitor weather conditions and will contact you if we need to reschedule due to severe weather. We work in most conditions, but extreme weather (heavy snow, ice storms, etc.) may require rescheduling for safety and quality reasons.

Our doors come with new locks. If you want all your home’s locks keyed alike, you can either:

• Have a locksmith rekey your new locks to match existing keys
• Have existing locks throughout your home rekeyed to match new locks
• Upgrade to keyless entry systems

We can discuss options during your consultation.

Decorative glass is easy to clean:

• Use standard glass cleaner and soft cloth
• Spray cleaner on cloth (not directly on glass) to avoid drips in crevices
• Wipe gently—decorative elements are durable but treat with care
• For caming (metal framework), wipe with damp cloth
• Avoid abrasive cleaners that could scratch

The glass is sealed within the door, so you only need to clean the exterior surfaces.

Defender doors provide exceptional security:

• 22-gauge steel construction (30-60% stronger than standard)
• All-steel edges (won’t crack or split like wood-edge doors)
• 40 Security rating (highest in the industry)
• Composite lock blocks with superior screw-holding power
• Ultra-Frame with nested strike plates in solid 18-gauge steel
• Magnetic weatherstripping creates tamper-resistant seal
• Optional super security locks and deadbolts
• Reinforced hinge systems

Storm doors add another layer with:

• 16-gauge steel construction
• Vault pins that prevent door removal even if hinges are taken off
• Steel-to-steel lock engagement
• Deadbolt security

While no door is 100% impenetrable, Defender doors are extremely difficult to breach. Our 22-gauge all-steel construction, composite lock blocks, and reinforced frames resist kick-ins, prying, and forced entry far better than standard doors or wood-edge doors. Combined with quality locks and our storm doors, you have multiple layers of security protecting your home.

No! All Defender steel doors are zinc galvanized, primed, painted, and baked. This multi-layer protection prevents rust and corrosion. Our doors are guaranteed not to rust for as long as you own your home. Even in Chicago’s harsh climate with salt, snow, and moisture, our doors maintain their integrity.

Steel doors provide excellent fire resistance compared to wood or fiberglass doors. Steel doesn’t burn, though extreme heat can eventually cause paint or finishes to deteriorate. The steel construction and solid core provide valuable time in a fire emergency. Always follow all fire safety protocols and maintain working smoke detectors.

Yes! Our composite lock blocks and solid steel construction provide excellent support for smart locks, video doorbells, and other modern security devices. The superior screw-holding power of our lock blocks ensures these devices mount securely. Consult the device manufacturer’s instructions for proper installation.

Absolutely! Our 16-gauge steel security storm doors provide significant additional security:

• Physical barrier makes break-ins much more difficult
• Locks engage from steel into steel frame
• Vault pins prevent door removal
• Allows you to open main door for ventilation while maintaining security
• Protects main door from tampering
• Visible deterrent to potential intruders

Many homeowners feel safer being able to open their main door for light and air while the locked storm door maintains security.

This is a personal preference:

• Peephole (included with all Defender entry doors) – Simple, no power needed, always works, no subscription fees
• Video doorbell – Can see who’s there from anywhere, records visitors, integrates with smart home, requires power and possibly subscription

Many homeowners use both for maximum convenience and security.

Yes! Door and window replacement consistently ranks among the top home improvements for:

• Return on investment (70-80% of cost typically recouped in home value)
• Energy savings (15-30% reduction in heating/cooling costs common)
• Improved comfort (elimination of drafts, better temperature control)
• Enhanced security (modern doors provide superior protection)
• Curb appeal (significant aesthetic improvement)
• Reduced maintenance (modern products require minimal upkeep)

Plus, you enjoy these benefits while you live in your home, making it a smart investment regardless of when you plan to sell.

Both approaches work:

All at once benefits:

• Maximum energy savings immediately
• Often better per-unit pricing
• Consistent appearance throughout home
• Single disruption period
• Faster return on investment

Over time benefits:

• Spreads out cost
• Can prioritize worst windows first
• Allows you to budget annually
• We can work with either approach. Many homeowners start with the most drafty windows and add more over time.

Consider:

• Door first if: Main door is in poor condition, security is a concern, door is most visible from street (curb appeal), door has significant drafts
• Windows first if: Multiple windows are drafty, windows are in worse condition, greater total energy loss through windows

Often the answer depends on your specific situation and budget. We can help you prioritize during consultation.

Yes! Homes with new doors and windows typically:

• Show better (great first impression)
• Photograph better for listings
• Have fewer inspection issues
• Command higher prices
• Sell faster than comparable homes with old doors/windows
• Appeal to move-in-ready buyers

Energy efficiency and security are top priorities for today’s buyers.

Energy-efficient doors and windows may qualify for federal tax credits, state rebates, or utility company incentives. Programs change regularly, so we recommend:

• Check IRS website for current federal tax credits
• Contact your utility company about rebate programs
• Ask your tax professional about deductions
• Research state/local efficiency programs

We can provide product specifications needed for any applications.
