“Went extremely well. Received detailed email several days prior to scheduled appt. that explained in detail the entire process… customer preparation before installation and what to expect during and post-installation. Crew of two was punctual and polite. Based on visual inspection, it appears they did an excellent and detailed job. I did the pre-installation prep work – i.e., removing old fiberglass insulation, vacuuming out box sill and providing clear pathway of approx. 3-4 ft around walls for crew to maneuver; doing the prep work saved me about $400.”
