I contracted with American Classic Exteriors to install a Pella Patio Door enclosure I had purchased at Lowe's Building Supply. Two installers arrived and removed the old window, installed the new window and did a perfect job. The caulked, installed extra insulation strips and repainted the trim molding. Some area needed new trim and they had extra wood in the truck to complete the job. Three hours labor for two people at a fixed price. Nicely done guys!!
