"We contracted Saunders to remove Vermiculite from our attic and thereafter air seal and re-insulate. We were very happy with the work as well as the customer service. Steve came to give us an estimate very promptly and then was able to schedule the work within a couple weeks. He was very informative regarding recommendations for a better energy efficient home, yet did not pressure us into any purchases. Afterwards they even helped us do an Energy audit in order to qualify for Focus on Energy incentives. We couldn't be happier with Saunders Insulation and will definitely call them for future projects!"
