Beautiful windows and doors can transform the way a home looks, feels, and functions. With Marvin’s attention to design and detail, professional installation is essential to help ensure your new products fit properly, operate as intended, and complement the character of your home.
At The Window Centre, we do not subcontract our installation work. By keeping installation in-house, we maintain direct oversight of each project and ensure our workmanship standards are carried through from initial fitting to the finishing details.
We believe quality products deserve quality installation. Our 2 Year Craftsmanship Warranty provides additional coverage for eligible installation-related concerns, giving you added confidence in the work performed by our team, separate from Marvin’s manufacturer warranty.
What Does Our Craftsmanship Warranty Cover?
For two years following substantial completion of your installation, The Window Centre stands behind the workmanship performed by our installation team, including:
-
Window & Door Alignment: Proper positioning, levelling, squaring, and initial adjustments to support smooth operation and appropriate clearances.
-
Installation & Secure Fitting: Correct fastening and installation of windows and doors in accordance with the scope of the original project.
-
Insulation & Weatherproofing: Installation-related shimming, insulation, perimeter sealing, and weatherproofing completed as part of the original installation.
-
Interior & Exterior Finishing: Workmanship associated with trim, caulking, and related finishing details included in your original installation agreement.
-
Workmanship-Related Corrections: Assessment and correction of deficiencies directly attributable to our original installation work, including necessary adjustments to address those deficiencies.
