40-Year Non-Prorated Door Warranty
Your new doors are protected with the same industry-leading warranty as our windows — 40 years of non-prorated, fully transferable coverage on every component.
What's Covered
Every key component of your doors is protected. Every detail is in writing.
Door Panel
40 years of full coverage on the door panel itself — entry, patio, and storm doors. Covers cracking, warping, delamination, and structural defects.
Frame & Threshold
Door frames and thresholds are warranted for 40 years. Covers warping, rotting, and any structural compromise that affects performance or seal.
Glass & Inserts
All glass components — sidelites, transoms, and decorative inserts — carry the same 40-year non-prorated coverage as our window glass.
Hardware & Locks
Handles, hinges, locks, and all operating hardware are fully covered. Every component is built to perform for the life of the warranty.

What does “non-prorated” mean?
It means the coverage never decreases. Whether it's year 5 or year 40, you have the exact same protection as on day one. Many competitors use pro-rated warranties where you pay an increasing percentage of replacement costs over time.
Is the warranty transferable?
Yes. If you sell your home, the full remaining warranty transfers to the new homeowner at no cost. This adds real resale value to your property.
What about the installation?
Our installation is backed separately. We also provide a free 3-year anniversary inspection where we visit your home to verify everything is still performing perfectly.
