Building in Cohasset

Local know-how for Cohasset homes

Cohasset is home to PLJ's South Shore office at 818 Chief Justice Cushing Highway, so we work here more than anywhere else on the South Shore. The town's rocky coastline faces Massachusetts Bay, with Cohasset Harbor, Little Harbor, Sandy Beach and the Jerusalem Road shore taking the full force of nor'easters. Inland, the Cohasset Common area and Beechwood hold antique colonials, shingle style houses and farmhouses on larger wooded lots. Salt spray, wind driven rain and long winters shape how we build decks, install siding and replace roofs here. Cedar shingles and painted clapboard are traditional, so details at trim, corners and windows matter. The Cohasset Common Historic District has its own commission that must approve exterior work before a permit is issued, and waterfront lots often need conservation commission review as well.

FAQ

Cohasset FAQ

Where is PLJ's South Shore office?

Our South Shore office is at 818 Chief Justice Cushing Hwy in Cohasset, MA 02025. All of our South Shore projects are run from there.

Do I need approval for exterior work near Cohasset Common?

If your home is in the Cohasset Common Historic District, yes. The district's commission must issue a certificate for exterior alterations before the town can issue a building permit. PLJ can help you prepare the application.

What siding holds up on an oceanfront home in Cohasset?

Cedar shingles and fiber cement both perform well on the Cohasset shore when installed over a proper weather barrier with careful flashing at windows and trim. PVC trim avoids the rot that wood trim often suffers in salt air.
