Therma-Tru warranty for doors
The short version
Therma-Tru doesn't cover everything, but keeps door system (slab, frame, glass, hinges, weatherstripping) covered for life. That full coverage is the same as most of the 6 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From Therma-Tru's published warranty, checked October 2026.

The fine print, decoded
What it leaves out
- Fading
- Normal wear and tear
Good to know before you buy
- Covers the original owner only, unless the door has Therma-Tru's transferrable warranty rider.
- Keep your receipt: claims need proof of purchase plus photos of the problem and the Therma-Tru stamp.
- Homes within 5 miles of salt water get less coverage on some parts and finishes.
