The work done by Brock Windows and Doors was exceptional. All communications done prior to the installation were clear and precise. On installation day, the crew set up and ensured that the work area was prepared with a drop cloth. The work area was cleaned during and after the installation. We are very happy with our new patio door and would highly recommend Brock Windows and Doors to any future customers considering replacing their patio door. The integrated blinds are fantastic and we are definitely enjoying the upgrade.
