energy savings, Insulation
"Recently had my attic insulated by Best Homes. Chris and his crew were professional and very efficient with their work. They insulated my attic within a few hours and left my house cleaner than it was before they got there. I wouldn't want the job done by anyone else."

"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"They were on time and installed a new gutter for me. They even installed part of the downspout for me because they said it was not in good condition. They did not charge me extra for that. I would highly recommend these guys."

"Connecticut Basement Systems prides themselves on their superior customer service, and they really live up to that. Their communication, quality of products and service, and attentiveness to customer needs is unsurpassed. Here are a couple of examples of how they go the extra mile for a satisfied customer: They installed their basement drainage system around my existing heating oil tank, but as I'm planning to convert away from oil this summer, they offered to come back AT NO EXTRA CHARGE once the tank is removed, to reroute the drainage system. Also, I was scheduled for a 3-day project, which included the replacement of some flooring in my basement. On the day the project began, we reconsidered the need for the flooring, and asked if we could cancel that portion of the job. They could not have been more accommodating to that adjustment, and made the change with no questions asked or negative attitude, even though it significantly lowered the price of the project and eliminated a whole day of scheduled work on 2-days' notice. That sort of total customer dedication is rare. I recommend them highly."
