1-year defect warranty.

1 year from the date the kit was professionally installed on your vehicle. Same for Standard and Ceramic.

Manufacturing defects in the film itself under normal use: bubbling that appears without impact damage, edge peeling that isn't from a car wash brush, purple-shift on Standard film, adhesive failure, and color fade beyond what's normal for the tier. If the film fails because the film was defective, we replace it free for the first 12 months after professional installation.

DIY installations (see below — this is the main exclusion). Install damage of any kind (cuts, tears, scratches, adhesion failure caused by contamination or improper prep). Environmental damage (rock chips through the glass, vandalism, fire, hail). Damage from ammonia-based glass cleaners used within the first 30 days. Tint removed by you or a shop for any reason. Damage caused by aftermarket window treatments or additional tint layers applied over ours.

The kit itself is designed for DIY installation, and thousands of people install our kits at home successfully — we even offer free 1-on-1 install support. But the manufacturer's defect warranty is only valid when the kit is installed by a licensed professional tint shop. If you install it yourself, you keep the kit, the install-support text line, and the guides — you just don't get warranty coverage. Choose based on how you want the risk balanced.

Roughly 80% of what people call 'film failure' is actually install failure: contamination trapped under the film, improper heat-shrinking, poor edge sealing, incorrect solution mix, or over-squeegeeing. Distinguishing manufacturing defects from install mistakes is only possible when a certified installer did the work. This is standard practice across the automotive tint industry — the professional shop's own warranty stacks on top of ours.

A dated invoice or receipt from a licensed automotive tint shop showing your vehicle, the installation date, and that our precut kit was the film installed. Photo or scan is fine, submitted with your warranty claim email.

Email windowtintkit@gmail.com with: your original order number (in your Stripe receipt), your professional-install invoice, a clear photo of the film failure, and a one-sentence description of what happened. We review claims within one business day and — if approved — ship a replacement kit at no cost. No return of the failed film required; simply have your shop remove and replace when the new kit arrives.

No formal registration. Your Stripe order confirmation is your proof of purchase; your shop's install invoice is your proof of professional installation. Save both.

No. The warranty is tied to the original purchaser and vehicle, and expires 12 months after professional installation regardless of ownership changes.

We investigate. If a second replacement fails within the original warranty window, we ship a third kit and work with you and your installer to identify the root cause — often it's a specific pane of glass, a workspace-environment issue, or a batch-specific defect. Original 12-month window applies to all replacements; it doesn't reset with each claim.
