DUNRITE INSTALLATION GUARANTEE & PRODUCT WARRANTIES
Products we install include:
1. A lifetime installation guarantee for as long as you own the home, and
2. The product warranty specified by the manufacturer.
DunRite Windows & Doors offers a Lifetime Installation Guarantee on our worksmanship and all man-made materials used in its residential installations for as long as the original purchaser of any window and/or door product from DunRite owns the home—ensuring that under conditions of normal use and service, the product installation will be free of defect in workmanship. The only exception is drywall and stucco, which have a two-year warranty.
This includes that:
- the caulking will be free of any blistering, peeling or flaking;
- the caulking seal will form a watertight barrier between home and window frame; and
- all component parts will be free from any installation-related defect.
DunRite’s guarantee is limited to only that which is directly related to installation and excludes wood windows, with or without cladding. It is exclusive to the original homeowner who made the purchase from DunRite and void once the home has been sold. Please refer to the purchase contract for specifics.
This installation guarantee is separate from the product warranty, which is solely dependent on what the manufacturer provides. Please refer to the warranty that accompanies a specific homeowner’s contract and/or the manufacturer’s website for specifics, exclusions and other details.

Frequently Asked Questions
Answers to common questions about AZ replacement windows
Window replacement costs in the Phoenix area depend on the window size, material, glass package and installation method. The only accurate way to price a project is to measure your specific openings, with an estimate for your specific product selections and measurements.
Choices of material, energy-efficiency upgrades, colors, style and the type of installation will determine the final cost. We provide detailed, current pricing based on your home – not outdated online ranges or generic averages.
Sources that provide a range of pricing on their website or in an article can be wildly inaccurate and outdated. For accurate, current pricing, contact a reputable window and door company if you’d like all windows replaced, or a handyman for just one or two window replacements. If you need glass replacement for a window not under warranty, any reputable glass repair company should be able to assist you.
DunRite’s Lifetime Installation Guarantee covers workmanship related to how your windows or doors were installed. As long as the original purchaser owns the home, DunRite will address any problems that are a direct result of improper installation. This excludes issues related to common wear and tear, improper use or modification of the product after installation, a lack of proper maintenance, and surfaces not protected by paint, stucco or other post-installation treatments specified by the installer. Coverage for commercial and investor properties differs from residential coverage, and wood products are excluded. Please refer to our contract for details.
Please remember product defects are covered by the manufacturer warranty, not the installation guarantee.
If a problem develops years later, the first step is identifying whether the issue is related to the product or the installation. If it’s a product defect—such as a seal failure in an insulated glass unit (IGU)—the manufacturer warranty typically applies. If the issue is related to installation workmanship or technique, DunRite’s installation guarantee applies. Because modern replacement windows are modular systems, many repairs involve replacing a specific component, not the entire window.
Manufacturer warranties usually cover the product itself, such as replacement glass units or hardware components. Labor coverage can vary depending on the manufacturer and the installer. Some installation companies include labor for warranty-related repairs, while others cover only the replacement part. At DunRite, we will coordinate warranty service for our customers, while doing our best to advocate for coverage and avoid out-of-pocket costs.
Yes, excluding screen replacement. Even when a repair falls under the manufacturer’s product warranty, DunRite will manage the process if we handled the original installation. We can identify the window model, confirm whether the issue is likely to be covered and help coordinate replacement parts, if needed. Because we work with these manufacturers regularly, we can often help homeowners navigate the process much more easily than they can do on their own. We also have the purchasing power to dispute denials of coverage that an individual homeowner might struggle with.
We’re here for our customers long after the installation is done. Quality replacement windows are designed to last for decades, but the occasional issue can pop up. Because replacement windows are modular systems, many issues can be addressed by replacing a specific component—such as a glass unit, sash or hardware—rather than replacing the entire window. When homeowners work with an established installer and a reputable manufacturer, warranty service and replacement parts are typically available for many years after installation.
We’re committed to being available for as long as a customer owns the home. If you have questions or think you might need to start a warranty claim, just give us a call.
If DunRite installed your windows, contacting our team is usually the easiest place to start. We can review your installation records, help determine whether the issue falls under the manufacturer warranty or installation guarantee, and guide the next steps. In many cases we coordinate directly with the manufacturer to order replacement parts, if they are covered.
If you’re unsure who installed your windows, or you know it wasn’t DunRite, the fastest solution for answers will be to directly contact the manufacturer. They keep records that are searchable by address, so they should be able to easily find the status of your specific warranty coverage no matter who installed the product.
If you look at the inside of a window frame, you can typically find a small label or logo. It might also be found on hardware, such as the window lock.
Warranty transfer policies vary by manufacturer, so it’s important to review the specific terms for each product in your home. A good starting point is to make a list of major components such as windows, doors, HVAC systems, roofing and large appliances, then visit each manufacturer’s website to review their warranty details.
Some manufacturers require the new homeowner to submit a transfer request within a certain timeframe—often within the first 30 days of ownership. Others may require a small transfer fee. If the deadline passes, the warranty may not transfer at all, so it’s best to confirm early.
Window manufacturers are often more flexible, sometimes only requesting documentation if a warranty claim is filed. Even so, it’s wise to review the transfer requirements in advance so you’re not surprised later on.
Even high-quality windows will perform poorly if they are not installed correctly. Improper flashing, sealing or structural installation can lead to drafts, water damage or operational issues that are unrelated to the window itself. That’s why both the manufacturer warranty and the installer’s workmanship guarantee are important parts of protecting your investment.
In most cases, a lifetime warranty means the window is covered for as long as the original homeowner owns the home. If the house is sold, the warranty may transfer to the new homeowner with reduced coverage or for a limited number of years. Each manufacturer defines “lifetime” slightly differently, and they almost always have exclusions and limitations on coverage. Reviewing the specific warranty terms on the manufacturer’s website is important.
A limited lifetime warranty means the manufacturer provides long-term coverage for certain parts of the window system, but the coverage applies under defined conditions. Limitations and exclusions, and/or prorated coverage may apply. Structural components such as the frame or insulated glass may be covered for the homeowner’s lifetime, while other parts like hardware, finishes or screens may have shorter coverage periods. Please check the manufacturer’s warranty for details, which can often be found on their website.
In most cases, any modification to a window after installation will void the warranty. For example, certain aftermarket window films cause heat to build up in the glass or prevent manufacturer insulation and coatings from performing as expected. Before applying window film or hiring someone to apply anything to window glass—especially if they claim it impacts energy efficiency–it’s a good idea to check with the window manufacturer.
Most high-quality replacement windows are designed to last several decades when properly installed and maintained. The exact lifespan can vary depending on materials, climate conditions and how well the windows are maintained. Strong warranties often reflect the manufacturer’s expectation that the product will perform reliably over a long period of time.
A product warranty comes from the manufacturer and covers defects in the window itself, such as glass seal failure or frame defects. A workmanship warranty comes from the installation company and covers issues related to how the window was installed, such as air leaks or water intrusion caused by installation errors.
Yes. Modern replacement windows are designed so that many components can be serviced individually. Depending on the issue, it may be possible to replace the insulated glass unit, a sash panel, rollers or hardware without replacing the entire window frame.
Most warranties cover defects in materials or manufacturing, not normal wear over time. Components that move regularly, such as rollers, hinges and balance systems, may eventually require adjustment or replacement after years of use.
Most manufacturers treat screens as short-term components, rather than lifetime parts of the window system. Screens are lightweight by design and can be easily damaged during normal use, so they are often covered for only the first year. After that point, damaged mesh can usually be repaired by replacing the screen material while keeping the original frame, often through a local screen repair company. Kits may also be available online or through your local big box home improvement store.
Modern replacement windows use insulated glass units made of two or more panes sealed together with insulating gas between them. If that seal fails, moisture can enter the space between the panes and create a foggy or hazy appearance that cannot be cleaned from either side. This condition is called glass seal failure, and it is one of the most common issues covered under manufacturer warranties for replacement windows.
Most major window manufacturers have long track records and established service networks, which helps ensure warranty support remains available over time. However, if a manufacturer discontinues a product line or leaves the market, replacement parts or compatible components are often still available through distributors or service providers. Working with well-established manufacturers and experienced installers helps reduce the likelihood of this situation and makes it easier to find solutions if service is ever needed.
