When choosing windows, homeowners and contractors alike look for products that combine durability, energy efficiency, and lasting value. Alliance Windows, available through Dunn Lumber, meet those expectations—and then go one step further with one of the most comprehensive warranties in the industry.
For contractors, that warranty becomes a selling point. For homeowners, it offers confidence that their investment will stand the test of time.
Lifetime Coverage for Parts
The Alliance Assurance Plus® Limited Lifetime Warranty ensures that window components are covered for as long as the original purchaser owns the home. This lifetime coverage applies to major parts such as vinyl frames, sashes, hardware, and balances. It’s a level of protection that simplifies conversations with customers and reassures homeowners that they won’t face unexpected replacement costs for essential parts.
Labor Included for the First Five Years
In addition to lifetime parts coverage, Alliance offers something many other manufacturers don’t: five years of labor coverage. If a factory defect requires repair during this initial period, the warranty covers not only the parts but also the labor needed to fix the problem. That’s a meaningful advantage for contractors who want to build trust with customers—and for homeowners who value peace of mind in the critical early years after installation.
Transferable Protection
Alliance’s warranty can be transferred once, to the next homeowner, for up to 20 years from the original installation date. This transferability adds value for homeowners who may sell their property. Instead of expiring at the time of sale, the warranty can move with the home, giving potential buyers confidence that the windows are still protected. For contractors, that feature provides another talking point when helping clients see the long-term benefits of choosing Alliance Windows.
What the Warranty Doesn’t Cover
As with any warranty, it’s important to understand the limits. The Alliance Assurance Plus® warranty does not cover damage caused by improper installation, misuse, acts of nature, or alterations such as painting or refinishing. Glass breakage is also excluded. By being transparent about these conditions, contractors can help customers set realistic expectations while still highlighting the strong coverage Alliance provides.
For contractors, this clarity reduces callbacks and warranty disputes. For homeowners, it ensures they know how to properly care for their windows so coverage remains intact.
Why Warranty Matters for Contractors
In a competitive market, contractors often need to differentiate not only their workmanship but also the products they install. Alliance’s warranty is a practical way to do that. Presenting customers with a warranty that combines lifetime parts coverage, five years of labor, and transferability creates an additional layer of trust. It signals that the contractor has chosen a manufacturer willing to stand behind its products long after installation.
That trust can translate directly into repeat business and referrals, especially when contractors emphasize that warranty support is backed by Dunn Lumber and its partnership with a respected manufacturer.
Why Warranty Matters for Homeowners
For homeowners, windows represent both a functional investment and a visible part of curb appeal. Choosing Alliance means knowing that the product is built to last—and that if a covered issue arises, parts will be replaced without extra cost for as long as they own the home. The five years of labor coverage adds an extra level of confidence in those early years when new homeowners are settling in and want assurance that their purchase is protected.
Transferability provides an additional selling point should they decide to move. A home with Alliance Windows can stand out in a crowded real estate market because buyers know the windows remain under warranty.
Building Value Over Time
Alliance Windows combine performance, style, and energy efficiency with a warranty that few competitors match. The Assurance Plus® coverage is designed to simplify the decision-making process for both contractors and homeowners, reducing risk and adding value over the long term.
Whether you’re a contractor looking to provide customers with products backed by strong protection, or a homeowner seeking windows that deliver peace of mind, Alliance Windows offer both. Backed by Dunn Lumber, they represent a choice that’s as smart as it is durable. Stop by and ask about Alliance Windows!
