Over thw course of 3 years. BVW custom made and installed every window and door in our home. Andreas, the President, personally came out for the first quote. He is nothing shy of fabulous! The quality of the product BVW created is fantastic. Leanne, in the head office, was delightful everytime we spoke or emailed. The install team (Eric, Darcy, and Wally) are literally ninjas. They are a great bunch of guys. We were always happy to see them arrive. The first round of installation was done the day of my husband's birthday party. You couldn't even tell the BVW ninjas had been here (save for the beautiful new view)! We were thrilled with BVW from the first phone call to the last day of install...and beyond. I would highly recommend this company.
