Warranty

Manufacturer warranty vs installation warranty: what is the difference?

The manufacturer covers manufacturing defects on the product per its policy. See our Warranties page. We cover our installation — 10-year installation warranty.

Why the distinction matters

A failed sealed unit ≠ leaking caulk. Knowing who is responsible speeds up the fix.
