At The Window Experts, we are committed to providing our customers with the highest quality products and services. In fact, this company was founded because our owner knew there was a different and better way to run a window company. It’s why we offer over a dozen brands of products, so you can have options, and it’s why we spent the time to develop our replacement window flashing system to ensure that your new windows will never leak due to the installation. It’s so good that it comes with a Lifetime Leak Free Guarantee. This guarantee gives you peace of mind, knowing that your windows will be free from leaks for as long as you own your home.

What Does Our Lifetime Leak-Free Guarantee Cover?
- Our lifetime leak-free guarantee covers workmanship that results in water leaking through your windows due to a faulty or failed installation.
What Does Our Lifetime Leak-Free Guarantee NOT Cover?

- Leaks from a homeowner error, like leaving a window open, are not covered.
- Leaks that originate from unrelated sources such as the roof, siding, dormers, stucco, brick, or other house leaks that manifest at the window are not covered.
