How We Work
A barrier only performs when it is continuous. We install air and water barriers with the rest of the wall assembly in mind, detailing penetrations and rough openings and sequencing the work with windows, insulation and cladding so each layer ties into the next.
Three Brothers Carpentry Corp. is based in Somerset, MA and supports projects across New England. Our team combines estimating, purchasing, cost control, field supervision and hands-on installation experience, so each scope is approached as one coordinated effort.
