Their sales guy and office staff were great but the installers were not, we have had them back 3 times now, once for a broken frame that their installer set a nail through by accident(stuff happens), once because the patio door was frosting up this cold February, they re-sprayed insulation around the door frame, and once to fill in 1 to 2 inch gaps in the outer caulking that they missed on the installation, these were at ground level that I could see. The sliding patio door has never sat flush in the door frame and there is a slight draft between the sliding doors. They have been good to come back and fix things but I would have expected a
better installation in the first place? Also wasn't impressed when the one of the crew asked for my wifi password so he could save on his cell phone bill.
