We were told at cottage show and over phone how easy this product was to install. Due to timing issues, we used our very experienced contractor to install the screens & doors. (who also installed all new doors and windows around our entire cottage) Sunspace screens were fine however we had major issues with the French Doors. After multiple calls and emails and two months, owner of GB Patio finally did a site inspection. They tried to shim and caulk the doors but to no avail. Light was still coming in 5 different spots. In December we checked the doors and weather was getting in. Not good. We reached out to Sunspace HQ and GB Patio and it seems as if we are being ignored. Not backing up their product. Very weak customer service and very frustrating to deal with.
