Lifetime Warranty

Thermoproof Lifetime WarrantyWhen 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, if you sell your home, our warranty is fully transferable and becomes a 15-year warranty from the original purchase date. This includes the glass, parts and labour, even the screen. And 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. We don’t exclude or reduce the period of the warranty if you live near the ocean.

Now, if your cat objects to being kept inside and makes an escape through the screen, well, we prefer not to get involved in domestic disputes.
