Professional Window Replacement: What to Expect – Part 3 Generous Warranty Terms and Guarantees

To maximize returns on your window replacement, make sure your new units come with a solid warranty coverage. This helps protect you and your investment better. Your chosen contractor should offer limited, fully transferable window warranties that cover:

Professional Window Replacement: What to Expect - Part 3 Generous Warranty Terms and Guarantees

  • Framing Material and Glass. These two components make up the entire structure of your windows. Given how framing material and glass are constantly exposed to the elements, they should come with coverage against defects. For example, Renewal by Andersen®️, one of the leading window manufacturers today, offers a 20-year warranty on their High-Performance Low-E4®️ SmartSun glass and on their Fibrex®️ composite material.
  • Hardware and Other Accessories. Your new windows should operate smoothly–they shouldn’t stick or jam–and should lock properly. That’s why hardware is usually covered by a warranty as well. Renewal by Andersen®️ offers a 10-year limited warranty on the frame, sash and locking mechanism, so you can always expect effortless operation and security from your new windows.
  • Workmanship. Aside from material, glass and accessories, most window warranties available also offer coverage on installation. This helps ensure you can avoid the hassle and additional costs involved with poor workmanship. One prime example of a good workmanship guarantee is the 20-year limited coverage on installation offered by Renewal by Andersen®️.

Window and workmanship warranties, however, may only cover material defects and poor installation. They won’t cover product failure and damage related to:

  • Product modifications or glass shading devices, such as glass tinting, insulated coverings, security systems and improper painting or staining.
  • Using and applying hardware, including locksets, hinges and closers that are not provided by the window’s manufacturer.
  • Improper maintenance, including the use of brick wash, razor blades or sealants, and improper washing and sanding.
  • Normal wear-and-tear sustained by the windows over time. These may include scratches, slight glass curvature and other imperfections.
  • Installation services by other than authorized window installers.
  • Tarnish and corrosion to hardware finishes.

Pro-Tip: Always read the fine print in your window warranties so you don’t do anything that can void coverage. Additionally, when investing in new windows, take note of the term of the warranty. Low-budget units typically offer only a 3-5 year coverage. Higher quality ones can provide coverage of up to 20 years, depending on the manufacturer.

Instead of DIY window replacement, invest in professional work. This way, you can enjoy peak performance from your windows for many years.


"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
