How do you compare entry door warranties? Learn the difference between manufacturer warranties and workmanship warranties, what coverage really matters, and how to choose an entry door built to last in the Quad Cities.
How Do I Compare Entry Door Warranties?
A warranty can tell you as much about an entry door as the product itself. While homeowners often compare door styles, colors, decorative glass, and pricing, the warranty reveals who stands behind the product—and who stands behind the installation.
The strongest entry door warranty isn't simply the one with the longest time period. It's the one that clearly explains what is covered, who provides the coverage, and how problems will be resolved if they occur. Understanding the difference between a manufacturer's warranty and a workmanship warranty is one of the smartest decisions a homeowner can make.
Manufacturer Warranty vs. Workmanship Warranty
Every quality entry door is really two separate investments: the product itself and the installation. Those two parts are typically covered by different warranties.
Manufacturer Warranty Covers:
- Fiberglass or steel door slab defects.
- Factory-applied finishes (subject to manufacturer terms).
- Insulated decorative glass units.
- Door components and selected hardware.
- Manufacturing defects in covered materials.
Workmanship Warranty Covers:
- Installation quality.
- Frame alignment and squareness.
- Proper shimming and fastening.
- Weather sealing and insulation.
- Threshold and hardware adjustments.
- Installation-related issues that develop over time.
Why Installation Coverage Matters
Homeowners usually notice installation problems long before they ever experience a manufacturing defect. A door that's slightly out of alignment can stick, allow daylight around the margins, create lock problems, leak water during storms, or develop drafts that reduce comfort throughout the year.
Those issues are almost always related to installation—not the door itself. That's why a written workmanship warranty is often just as valuable as the manufacturer's warranty.
Questions Every Homeowner Should Ask
- Who provides the workmanship warranty?
- How long does the labor warranty last?
- Is the warranty provided in writing?
- What happens if the door begins sticking or leaking?
- Who performs warranty service?
- Are adjustments included after installation?
- Does the contractor stand behind the complete installation?
Look Beyond the Door Slab
An entry door is only one part of the complete system. Long-term comfort, security, and durability depend just as much on the frame, threshold, weatherstripping, hardware, and installation as they do on the fiberglass or steel door itself.
A trustworthy contractor should explain the installation process in plain language. Homeowners should understand how the opening will be prepared, how the frame will be squared and shimmed, how insulation and sealing will be completed, and how the final adjustments will ensure smooth operation and weather-tight performance.
Don't Forget the Security Details
Many of the most important features of a quality installation are hidden after the project is complete. Before signing a contract, ask about:
- Reinforced strike plate locations.
- Long screws that anchor into the structural framing.
- Composite or rot-resistant jamb options.
- Manufacturer-approved hardware compatibility.
- Professional sealing and flashing techniques.
- A written workmanship warranty.
What Does FGIA (Formerly AAMA) Say?
The Fenestration and Glazing Industry Alliance (FGIA), formerly the American Architectural Manufacturers Association (AAMA), publishes performance standards and installation best practices for entry door systems. These guidelines emphasize that proper preparation of the rough opening, flashing, shimming, fastening, insulation, weather sealing, and final adjustment are essential to achieving the door's tested performance.
In other words, even the highest-quality entry door cannot perform as intended if it is installed incorrectly. Comparing warranties should always include evaluating the contractor's commitment to installation quality—not just the manufacturer's product coverage.
Why Quad Cities Homeowners Choose Suburban Construction
Since 1985, Suburban Construction has completed more than 40,000 exterior remodeling projects throughout Eastern Iowa and Western Illinois. President JR Girskis and Vice President Darin Wilson believe homeowners deserve complete confidence in both the products they purchase and the craftsmanship behind every installation.
Every Therma-Tru® entry door installation is carefully measured, professionally installed, and thoroughly adjusted to ensure proper operation, weather resistance, energy efficiency, and lasting curb appeal. Their team takes the time to explain the installation process so homeowners understand exactly what they're receiving—not just on installation day, but for years afterward.
The Value of Suburban Construction's Lifetime Written Workmanship Warranty
Every entry door installation from Suburban Construction is backed by a Lifetime Written Workmanship Warranty. While manufacturers warranty the door slab, decorative glass, and individual components according to their published policies, Suburban stands behind the craftsmanship of every installation.
That means homeowners receive lasting protection for the installation itself—including proper frame alignment, weather sealing, threshold adjustment, hardware operation, and the overall quality of the completed entry system. It's a commitment that reflects confidence in the installation, not just the products being installed.
The Bottom Line
The best entry door warranty combines two things: a reputable manufacturer's product warranty and a contractor who confidently stands behind their workmanship. When comparing proposals, look beyond the length of the warranty and ask what is actually covered. A professionally installed entry door with a comprehensive workmanship warranty provides peace of mind, dependable performance, and a welcoming first impression that stands up to years of Quad Cities weather.
