Fiberglass insulation for Sudbury builders and homeowners

For new construction and additions in Sudbury, fiberglass batts are a reliable way to meet code at a sensible cost. We schedule around your framing and drywall so inspections stay on track.

When older homes are opened up for renovation, fiberglass batts in the open walls, combined with air sealing, bring them much closer to new-construction performance.

Because Sudbury is close to our Westborough office, we can usually see your property within days.

Local homes

Sudbury homes and what they need

Sudbury is mostly larger single-family homes, many colonials and contemporaries built from the 1950s through the 1990s, plus historic homes near Sudbury Center.

Sudbury is a largely residential town along the Sudbury River, with historic homes around Sudbury Center and many larger colonials and contemporaries built from the 1950s on. Big homes with cathedral ceilings, skylights and finished attics often have hidden air leaks we find with blower door testing.

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.

FAQ

How long does a fiberglass job take?

Most homes and additions are done in a day or two.

Does fiberglass help with sound?

Yes. Unfaced batts in interior walls and floors reduce noise between rooms.

Will fiberglass pass inspection?

Installed to the required R-value with no gaps or compression, yes. We know what inspectors look for.

Is fiberglass safe?

Yes, once installed and covered. Our crews wear protective gear during installation.

Can fiberglass go in an existing wall?

It depends on the location and the vapor control needed. We follow code and manufacturer guidance.
