The folks from Brock were excellent. We couldn’t have asked for more personable, hard-working installers. They were efficient, worked quickly, and went the extra mile. They followed all Covid protocols to ease any worries. Our salesman was also very helpful and attentive. The paperwork was easy to complete. they ensured that the products we wanted were exactly what we got. They walked us through all the pros and cons before our final decision. The windows look excellent. We would recommend them to everyone.
