No-hassle Lifetime Warranty

Our unparalleled No Hassle Lifetime Warranty covers installation, parts, glass and screens, and lasts for as long as you live in your home. Plus it is transferrable if you sell your home.

When you purchase Thermoproof windows or patio doors, you’re also purchasing peace of mind.

We warranty our products for as long as you live in your home. And we don’t exclude or reduce the period of the warranty if you live near the ocean. We know that rain and salt air are a part of life here on the Island and design our products with the elements in mind.

If you sell your home, our warranty is fully transferable and becomes a 20-year warranty from the original purchase date.
