Marshfield houses, built for weather and remodeled for it

What a 1969 median year built means inside the walls

Census figures put Marshfield at about 25,800 people in roughly 11,600 homes, and the median house was built in 1969. That is the era of the raised ranch, the garrison colonial and the expanded Cape. Those houses were framed well enough, but they were wired, plumbed and insulated for a different set of expectations. In practice that usually means a sound house ready for its second or third round of updates, not a teardown.

When we open a wall in a house of that age we expect to find thin fiberglass or none, two-prong circuits that have been added onto more than once, and bathrooms that have been retiled over the original tile. Anything built before 1978 gets treated as possible lead paint, so we set up lead-safe work practices before the first piece of trim comes off.

About 13 percent of Marshfield's homes predate 1940. Those are a different job: plaster on lath, balloon framing in some, and sills that may have sat close to grade for a century. We look at the framing before we put a price on the finish work, because what is under the floor decides what the kitchen can be. A floor that has sagged over a sill problem gets fixed before cabinets go on it, not shimmed around.

The coast is part of every exterior scope

A town with more than three square miles of water inside its lines lives with wind-driven rain and salt in the air. Decks lose fasteners, flashing corrodes, and roofs on the exposed side of a house age faster than the sheltered side. When we write a scope for a Marshfield deck or roof, we specify materials and fasteners for that exposure rather than for an inland yard.

Ice dams are the other recurring problem on South Shore houses of this vintage. The fix is rarely just new shingles. It usually means air-sealing the attic floor, adding insulation, and making sure the roof can vent, and we tell you that before the roofing number is on the table.

New footings for a deck or addition go below frost depth, which in Massachusetts is commonly about four feet. Near the coast we also check how the yard drains before we decide where a footing goes. A deck that ponds water against the house, or a gutter dumping onto a footing, will undo good framing in a few seasons, so drainage is written into the scope alongside the lumber.

Remodeling a house you plan to keep

Roughly 80 percent of Marshfield homes are lived in by their owners, and about 82 percent are single-family detached. That points to the work people actually call about: kitchens that have outgrown a 1970s layout, a second full bath, a primary suite over the garage, a basement that finally gets finished. With about 14 percent of homes built since 2000, some calls are about newer houses whose open plans still need a pantry, a real laundry room or a basement finished the way the builder never got to.

With a house you intend to stay in, the decisions last. We walk the house with you, write the scope room by room, and say plainly which walls carry load and which can come out. Permits go through the town building department under 780 CMR, and the inspections land at rough framing, insulation and final, with the licensed electrician and plumber handling their own. If a wall shows something unexpected, like an old roof leak that rotted a top plate, we stop, photograph it and walk you through it.
