Fairfield, CT

***** Blown-In Insulation

I was quite impressed with Thermal Barriers,Inc., and particularly impressed with Tom Semo (the owner). They contacted us soon after we submitted our project to ServiceMagic; came by to provide an estimate at the exact time they said they would; suggested solutions to several insulation problems outside of the scope of what we asked them to do; and performed the task we hired them for in an efficient, competent manner - without disrupting my wife's work (she has a home office and is on the phone constantly). The work was performed without causing a big mess. They also protected our floors and stairs and cleaned up the small amount of material that got tracked into the house. I'm pleased with results and very pleased with what they charged us - and I've already recommended them to several coworkers.
Ed Perrault, Westport, CT

***** Blown-In Insulation

Tom Semo is a man who knows what he is doing. He came on time to provide the estimates and completed the job on the day he said he would. His crew even cleaned up after the fact. He explained everything about insulation, spend time understanding my problem and came up with a solution to potentially resolve it.
