Replacing your home’s windows is one of the most significant investments you can make in your property. It enhances curb appeal, improves energy efficiency, and elevates your daily comfort. However, as homeowners across our diverse regions—from the sun-drenched desert of Phoenix to the snowy peaks of the White Mountains—begin their research, they often encounter a confusing landscape of warranty details.
A critical question often arises too late in the process: Does the warranty cover just the window itself, or does it also cover the installation?
This distinction is paramount. A window is only as good as its installation, and a warranty that leaves a gap between the product and the workmanship can lead to unexpected costs down the road. Whether you are battling salt air in Cape Cod, high-altitude UV rays in Denver, or extreme heat in Las Vegas, understanding the scope of your warranty protection is essential for securing the long-term value of your replacement project.
The Fundamental Distinction Between Product and Installation Warranty Coverage
To make an informed decision, it is vital to understand that in the general window industry, "warranty" often refers to two separate agreements provided by two separate entities.
- Manufacturer’s Product Warranty: Provided by the company that makes the window. It typically covers defects in materials. For example, if a piece of hardware fails or a frame component shows a manufacturing flaw, the manufacturer is responsible for the part.
- Contractor’s Installation Warranty: This is a separate "workmanship" warranty provided by the local contractor who installs the windows. It covers errors such as improper caulking or misalignment. These are often significantly shorter than product warranties—sometimes lasting only one or two years.
The Coverage Gap: The danger for homeowners lies in the gap between these two coverages. If an issue develops five years later, the manufacturer may blame the installer, while the installer may blame the product. This finger-pointing can leave the homeowner stuck with the bill for labor and repairs.
Renewal by Andersen’s Comprehensive Warranty Approach
Renewal by Andersen (RbA) eliminates this gap by offering a single-company solution. Because we manufacture the windows and employ Certified Master Installers to install them, our warranty covers both the product and the installation.
For homeowners in RbA regions, this provides a unified level of protection:
- 20-Year Glass Coverage: Covers glass and glass seal failures.
- 20-Year Material Coverage: Covers our proprietary Fibrex® material against flaking, rusting, blistering, peeling, cracking, pitting, and corrosion.
- 10-Year Hardware Coverage: Covers locks, lifts, and balance systems.
- Lifetime Installation Coverage: Critically, we offer lifetime coverage on installation labor for as long as the original homeowner remains in the home.*
This integrated approach means there is no finger-pointing. If an issue arises, you have one point of contact and one company accountable for the solution.
How Do Regional Environmental Factors Impact Warranty Coverage?
RbA serves a vast range of climates. A warranty that works for a mild climate might be insufficient for the extreme conditions found in our specific regions.
Extreme Heat and UV Exposure
In places like Phoenix, Las Vegas, and across Texas, windows are subjected to intense solar radiation. Extreme heat can cause materials to expand and contract, stressing components. Renewal by Andersen’s Fibrex® material is engineered to maintain stability in extreme heat, and our warranty includes no heat-related restrictions.
Coastal and Salt Air Corrosion
Homeowners in Martha’s Vineyard, Cape Cod, and along the Connecticut and Rhode Island coasts face corrosive salt spray. Many competitors’ warranties explicitly exclude coverage for homes located near a coastline. Our warranty has no coastal restrictions because Fibrex® material inherently resists saltwater corrosion.
High Altitude and UV Intensity
For residents in Denver, Boulder, Flagstaff, and Reno, altitude presents unique challenges. Lower atmospheric pressure can cause standard glass units to distort if not properly handled. Our products are engineered for high-altitude performance, and our warranty contains no altitude limitations.
Does the Warranty Cover Labor Costs or Just Parts?
One of the most common "gotchas" in window replacement is a warranty that covers parts but not labor. If a standard window part fails 10 years down the road, the manufacturer might send you a free replacement sash, but you are responsible for the cost of hiring a contractor to install it.
Renewal by Andersen offers a non-prorated, fully transferable limited warranty that includes both parts and labor. If a covered issue arises, we handle the repair or replacement at no cost to you.
Why is Professional Installation a Prerequisite for Warranty Validity?
Almost every window warranty states it is void if the product is not installed according to exact specifications. In different geographic areas, where environmental challenges are high, the precision of the installation is critical.
- Sealing: In Phoenix, sealants must withstand heat without drying out.
- Flashing: In Cape Cod, flashing must be integrated perfectly to manage wind-driven rain.
Because we trust our Certified Master Installers, we back their work with lifetime installation coverage, ensuring the seal between the window and your home remains secure.
Is the Warranty Transferable to New Homeowners?
In active real estate markets like Austin, Denver, or Boston, a transferable warranty is a powerful selling point. Renewal by Andersen’s warranty is fully transferable to the next homeowner. It transfers automatically, with no paperwork required and no transfer fee, adding tangible value to your property.
