Insulation Contractor in Medfield, MA
Medfield, Massachusetts was incorporated in 1651, burned during King Philip's War in 1676, and rebuilt with the heavy timber framing that still holds up some of its oldest walls today. That kind of age changes what is actually inside a wall cavity, and it changes how we insulate it.
Post, beam, and peg, the frame behind Medfield's First Period houses and the cavities we still open today.
The town that was settled, then burned, in its first twenty-five years
Medfield grew out of Dedham, which voted to allow a new settlement in November 1649. Ralph Wheelock led the founding alongside Thomas Wight and Robert Hinsdale, and after settlers paid Dedham fifty pounds for the land, the General Court incorporated the town as the 43rd in Massachusetts on June 2, 1651. By 1660 about 234 people lived there.
The town did not stay peaceful for long. On February 21, 1676, during King Philip's War, several hundred Native American fighters under the Nipmuc leader Monoco attacked Medfield as a frontier settlement, burning 32 houses, two mills, and many barns, and killing seventeen colonists. Philip Street and Metacomet Street in the town today still mark that day.
Nothing standing in Medfield now predates that fire. Every house described as a Medfield antique, including the oldest in town, was built or rebuilt after February 1676, using the timber-frame construction of its own time rather than anything a modern framing crew would recognize.
What survived the rebuilding, and what timber framing means for a wall today
A handful of Medfield's rebuilt houses are still standing. The Peak House, whose original 1651 dwelling burned on the same February day as the rest of the town, was rebuilt around 1677 to 1680 with one of the highest-pitched colonial roofs on record in Massachusetts, gained an addition in 1711, and was moved to its present Main Street site in 1762. The Medfield Historical Society has run it as a house museum since 1924. The Dwight-Derby House dates to 1697, and parts of the Lowell Mason House go back to the town's first year, 1651.
Houses from this period, and many built well into the 1700s, are timber framed: heavy corner posts and beams do the structural work, with lighter studs filling the wall between them, plaster and lath on the inside face, and clapboard nailed more or less straight onto that frame on the outside. There is usually no sheathing layer behind the clapboard at all, so the cavity sits closer to open air than a modern wall does. The framing itself was hand-hewn and set by eye, which means bay widths shift from wall to wall, and no two houses use quite the same spacing twice.

What's different
What we never do
Where Medfield's oldest streets sit, and how we get there from Franklin
Route 109 crosses the Charles River as it enters Medfield from Millis, then runs through the town center, where it meets Route 27. Much of the town's oldest housing sits close to that crossing, along the streets that filled in around the meetinghouse and the common in the century after the fire. The Charles River itself borders close to a third of Medfield's edge, marking the boundary with Millis before curving back into town.
Medfield never grew into a mill town the way some of the towns around it did. Its two mills burned in 1676, and the town's growth after that stayed closer to a farming village filling in around its center than to the water-powered manufacturing that shaped Millis and Medway downstream. That history is part of why Medfield's oldest houses cluster tightly near the town center rather than spreading across a former mill village.
Our crew works out of 1000 Chestnut Street in Franklin, which puts Medfield and the rest of the Norfolk County towns we cover within a same-day drive. Reaching the town center, or an address further out along Route 27, is not a special trip, whether the visit is the assessment or the install day that follows it.
From the first postwar subdivision to the newest one, not yet built
Medfield's first subdivision broke ground in 1948, as the postwar housing boom reached the town the way it reached most of Massachusetts, and the capes and colonials built in the decades since make up a large share of the town's housing stock. Those houses use conventional stud framing and sheathing, a different problem entirely from a timber-framed First Period house, but a cape's knee walls and low sloped ceilings still tend to carry whatever thin insulation the house was built with and nothing more.
The newest chapter in Medfield's housing history is still being written on the old Medfield State Hospital campus. The hospital opened in 1896 and operated for more than a century before closing in 2003. The town acquired the 128-acre, 44-building campus from the Commonwealth in 2014 and spent four years on a reuse master plan that won a 2019 award from the American Planning Association. Town meeting approved a redevelopment agreement with Trinity Financial in June 2022 for roughly 334 rental units, with about a quarter of them income-restricted, an arts space in the old Lee Chapel, and preservation of the campus's historic buildings, with the project moving into permitting after that vote. When those units are finished, they will be the newest housing stock in a town where the oldest still standing dates to the 1670s.
From assessment to a finished wall, on a house of any age
Assess the house
The crew checks the era of the framing against what is actually behind the plaster or drywall, in the attic, the walls, and the basement or crawl space, before anything is quoted.
Write the scope and the paperwork
Findings go into a written scope, and where the house qualifies, to the Mass Save Home Energy Services program for approval before a crew is booked to come back.
Air seal first, always
Gaps at the rim joist, the attic hatch, and every wall penetration get closed before any material goes in, on a 1670s frame or a 1990s one. That order does not change.
Insulate to the era
Material is matched to what the framing and the cavity shape actually allow, whether that is a dense-pack timber-frame bay, a balloon-framed wall checked top to bottom first, or a straightforward attic top-up.
Walk it with the homeowner
Everything in the scope gets checked before the crew leaves, and because the office is in Franklin, a short follow-up visit is never a long drive.
What decides the cost of a Medfield job is less the size of the house than its age and what is behind the wall: whether a cavity has to be opened and checked before it can be filled, whether old material has to come out first, and how many separate areas the written scope actually covers. Most single-measure jobs finish in a day, and a wall or attic filled to the depth the house needs holds its performance for decades, with no maintenance beyond keeping the attic hatch and any access points sealed the way they were left.
Through the Mass Save Home Energy Services program, eligible Medfield households can receive incentives covering up to 75 percent of qualifying insulation upgrades, confirmed through a free home energy assessment before anything is booked.
Active and verified as of July 2026. The registration belongs to Baystate Energy Reduction LLC, and the license is held by Douglas J. Stewart, Owner. Given how much of Medfield's housing stock predates modern framing, the services that come up most here are air sealing done before anything else, wall insulation packed bay by bay into timber-framed cavities, insulation removal where an earlier owner filled a bay badly, and blown-in insulation for the postwar and newer attics, all part of our broader insulation services.
Frequently asked questions
Yes. First Period and colonial-era Medfield homes get their wall cavities opened and checked before anything is dense-packed, since the frame and the bay widths were set by hand and never match a modern layout. Nothing is filled blind.
It changes the plan, not whether the work can happen. Active knob-and-tube wiring is never buried under insulation, so the assessment maps exactly where it runs before any bay near it is touched.
Often, yes. Framing to code the day a house was built is not the same as insulated to what the house actually needs, and a rim joist or attic hatch sealed to the day's minimum is a common gap even in newer construction.
Insulation upgrades are eligible under the Mass Save Home Energy Services program, which can cover up to 75 percent of the approved cost for a qualifying household. A free assessment maps the scope first, so the paperwork submitted reflects the house rather than a guess.
Find out what your Medfield house actually needs
The assessment is free, it starts by figuring out what era your walls actually are, and it ends with a written scope before anything is opened or filled.
