Draft Stopping & Fireblocking in Upton, MA
Builders across Worcester County rely on our crews for fireblocking at plates, chases and penetrations, scheduled around inspections.
Built for Upton
Why fireblocking matters in Upton buildings
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 Upton.
When older buildings are renovated, open balloon-frame walls often need new fireblocking at each floor line before inspection.
Upton is minutes from our Westborough, MA headquarters, so estimates and follow-up visits are easy to schedule.

Upton homes and what they need
Upton is a rural town of mostly single-family homes, from antique colonials and farmhouses to newer homes on larger lots, many heated with oil or propane.
Upton is a rural town around Pratt Pond and Upton State Forest, with many homes on larger wooded lots. Antique colonials, farmhouses and homes heated with oil or propane are common here, so sealing attics and basements can cut fuel use noticeably.
Worcester County homes heated with oil or propane often see the fastest payback from sealing air leaks, because every gallon saved is money that stays in the house.
