Why the 3M Warranty Matters
3M offers one of the best warranties in the window film industry — but it is only valid when the film is purchased and installed through an authorized dealer. Buying film online or hiring an unauthorized installer voids the warranty entirely.
Warranty Terms
Coverage varies by product and application:
- Residential: lifetime warranty
- Commercial interior (Prestige): up to 15-year warranty
- Commercial exterior film: typically 5-year warranty
- Safety and security film: multi-year warranty terms
- DI-NOC architectural finishes: separate warranty terms
What the Warranty Covers
The 3M warranty protects against manufacturing and adhesion defects:
- Delamination
- Bubbling
- Peeling
- Color change
- Adhesive failure
What Voids the Warranty
A few things will void coverage:
- Improper cleaning (abrasive cleaners or tools)
- Physical damage to the film
- Non-authorized installation — this voids the warranty immediately
The Authorized Dealer Requirement
This is the most important point: if you buy 3M film online or have it installed by an unlicensed installer, the warranty is void — period. As an authorized dealer, we register your installation so your coverage is real and enforceable.
Our Installation Guarantee
