Draft stopping and fireblocking for Hudson builders
Concealed spaces inside walls, floors and chases can carry fire from one level to the next in minutes. Fireblocking closes those paths with approved materials, and it is required by code in new construction and many renovations in Hudson.
Multifamily buildings need continuous fireblocking and draft stopping between units and floors, and that is where much of our work happens.
Being close to Westborough means our crews know Hudson well and can schedule quickly.

Know your Hudson home
Hudson has a compact downtown with older single- and two-family homes, plus mid-century and newer single-family neighborhoods.
Hudson grew along the Assabet River, and its compact downtown is surrounded by older single- and two-family homes, with newer neighborhoods toward Lake Boon and the Marlborough line. Lake-area homes converted from seasonal cottages often need insulation brought up to year-round standards.
Middlesex County's older cities have many homes with balloon framing and empty walls, while its suburbs have large attics and bonus rooms that leak air.

Insulation targets and incentives in Hudson
Climate & code
Climate zone 5A targets
Hudson is in IECC climate zone 5A. For attics in zones 5 and 6, ENERGY STAR recommends R-49 to R-60, and many existing homes here have far less. Many Massachusetts towns have adopted the Stretch Energy Code or the Specialized Opt-in Code, which raise insulation and air-sealing requirements for new construction and major renovations.
