"We had this company come to do insulation for our whole home - attic and walls (through Mass Save). Not only did they do what was in the original contract, but they also added insulation to our garage ceiling AND to an open wall that was being worked on for an unrelated home reno project! They did 3 days of work in 1 day & stayed late to vacuum and clean up. They were very professional, extremely efficient, and I love that it's a family operated company. Ivan, their office resource who helped book the appointment, was also a pleasure to work with throughout the process. We highly recommend using this company for any insulation needs."

Family owned business since 1964. Specializing in the installation and finishing of traditional hardwood flooring. Our sanding process is completely sealed off from the rest of the house so there is minimal to no dust outside of the work area. All work is performed and supervised by the owner.New Hampshire number 603-881-5052. Mass number is 978-597-2333

"Lou Toppia was just the expert I needed. Not only was I expecting him to refinish my hardwood floors, I was asking him to come in and work miracles to repair the damage done by another contractor who had a damaged machine created wavy distortions to my floors. Lou made them look beautiful again! He was very honest about what he could and could not make perfect and his work always exceeded my expectations. Lou was careful to keep his work area very clean, cleaned up after himself daily and protected my other living areas by sheeting off the rooms he was refinishing. The final finish is so beautiful, with four coats of satin urethane, I think they look better than the factory finish. I would highly recommend Lou to anyone in need of hardwood flooring installation or refinishing."
