My experience with Verdun could not have been any better. The salesperson, Max visited our home and explained all the options that would meet our budget and needs. Max was honest, respectful, professional and absolutely delightful!

We were looking to replace our front door and had engaged a few companies for an on site visit and estimate. Verdun Windows and Doors were rated A + on the Better Business Bureau site. The service was fast and friendly, the installation was first rate.
