Installation & Warranty

Window Installation Services & Quality Assurance Program

AVI’s Marvin-authorized, factory-trained installers can take window and door installation off your hands, for time and cost-effective results.

When you choose AVI for your Marvin windows and doors, you can rest assured that we stand by our craftsmanship with a 10-year installation warranty. All Marvin products carry a limited 10-year warranty covering manufacturer defects, materials and workmanship.

If you choose to self-install or hire an outside contractor, our Quality Assurance Program (QAP) supports your success with pre-installation training and an assessment of the work before walls are closed. QAP provides any corrective measures needed to prevent future warranty and product performance issues.

If you have purchased Marvin windows and doors and wish to submit a warranty claim, please refer to Marvin’s warranty page.
