Insulation Contractor Serving the Town of Norfolk, MA
Norfolk is the town on the Franklin/Foxboro commuter rail line, not the four-county Norfolk County we also serve, and the two get mixed up more than they should. This page is about the town: a former railroad village that split off from Wrentham in 1870, with a compact, older center around the depot and a much larger stock of houses built as the town filled in through the twentieth century. Which one your house is decides most of the insulation scope, and that split is what the rest of this page is built around.
Norfolk's houses span from the 1850s railroad village around the depot to subdivision building that has continued for decades since.
The town of Norfolk, not the county, and what that means for scheduling
Norfolk the town sits in the northern part of Norfolk County, along Massachusetts Route 115, which runs through the town center as Rockwood Road before continuing on toward Millis and Sherborn. The town's own commuter rail station, on the MBTA Franklin/Foxboro Line, sits right at 9 Rockwood Road next to the grade crossing in the town center, a stop rebuilt with a new platform and parking lot in 1990. Route 1A crosses through town as well, and Stony Brook Wildlife Sanctuary holds a stretch of conservation land on the town's western side. None of that describes Norfolk County as a whole, which is the wider four-county area covered on our Norfolk County service area page, alongside the other towns and counties we work in.
For a Franklin-based crew, Norfolk is close enough that a morning assessment and an afternoon install day are both realistic on the same visit, without the scheduling padding a longer drive would add. That matters for a town where, as the build-era split below shows, the scope on one street can look nothing like the scope two streets over.
Why Norfolk's housing stock splits into two very different jobs
Norfolk incorporated on February 23, 1870, carved out of North Wrentham along with sections of Franklin, Walpole, and Medway, once the railroad village around the depot had grown enough meetinghouses, stores, schools, and a rail stop to justify separating from Wrentham. That railroad village is still standing. The Rockwood Road Historic District, added to the National Register of Historic Places in 2017, covers the stretch of Rockwood Road from the commuter rail line to Boardman Street, and most of its houses date to between about 1850 and 1900, built as the Norfolk County Railroad brought the town its first sustained growth.
The rest of Norfolk tells a different story. The town's population grew quickly after 1925, once a hospital and a state prison were built there, and its own history records major residential development before 1940 in the Pondville and Clark Streets section, with suburban building continuing in Norfolk ever since. That later wave is what fills most of the town today: houses framed well after wall insulation was standard, built in a different decade of code and a different style of construction than the village center around the depot. A crew working Norfolk on any given week is usually moving between those two very different kinds of houses, sometimes on the same day.
Older village center or later subdivision, pick your Norfolk house
The recommended scope below is not the same for both kinds of Norfolk house, because the problem behind the walls is not the same. Pick the description closer to your house and the scope changes underneath it.
Which kind of Norfolk house is yours
Village-center home, built before 1900
Framed before insulation was ever part of a house plan, in balloon construction that needs fire blocking addressed before a wall cavity can be packed.
- Exterior wall cavities checked for insulation, usually found empty behind the plaster
- Wiring cleared by an electrician before any bay near knob-and-tube is dense-packed
- Attic checked for depth over shallow original rafters, with baffles added where needed
- Rim joist and sill areas checked, since many were never touched after construction
How a Norfolk insulation job runs, once the era is known
The order below is the same for a Rockwood Road-era house and a subdivision ranch outside the village center. What changes is what the crew finds at each step, which is why the assessment comes before anything else.
Free assessment maps the house
A free home energy assessment checks wall framing, attic depth, wiring, and rim joist condition against the era the house was built in, whether that is a village-center home near the depot or a later subdivision build.
Scope goes to the utility program
The written scope from the assessment is what goes to Mass Save for approval, so the incentive is confirmed before any work is scheduled.
Access points are opened
Attic hatches, wall bays, or basement rim joists are opened exactly where the scope calls for it, no more and no less than the assessment found.
Material goes in
Cellulose or fiberglass is installed to the depth or density the scope specifies, whether that is topping off a subdivision attic or dense-packing an empty village-center wall.
Access points are closed
Hatches, plugs, and any disturbed drywall or siding are put back the way they came, so the house looks the same as before the crew arrived.
Walkthrough confirms the scope
The crew walks the house with the homeowner to confirm every item on the written scope was completed before calling the job done.
Mass Save, licensing, and the Norfolk services that matter most
Through the Mass Save Home Energy Services program, eligible Norfolk homeowners can receive incentives covering up to 75 percent of qualifying insulation upgrades, which is often the difference that makes a full-house scope realistic in one visit rather than spread across a few years.
Active and verified as of July 2026. Both the registration and the licensed supervisor apply to every Norfolk job, from a Rockwood Road-area colonial to a subdivision ranch across town.
Wall insulation
The default call for village-center homes with wall cavities that were never filled when the house was framed.
See wall insulationAttic insulation
Relevant on both sides of town, but for different reasons: shallow original rafters near the depot, settled or code-minimum depth in later subdivisions.
See attic insulationAir sealing
Closes the gaps around outlets, hatches, and penetrations that show up in both a nineteenth-century frame and a mid-century subdivision build.

Frequently asked questions
This page is about the town of Norfolk, the small town on the Franklin/Foxboro commuter rail line that split off from Wrentham in 1870. Norfolk County is the much larger four-county-spanning region that the town sits inside, described further up this page.
Often, yes. Houses in and around the Rockwood Road Historic District near the depot tend to date to the 1850 to 1900 period, framed before wall insulation was standard practice, which usually means an empty wall cavity behind the plaster and, in some houses, wiring that has to be cleared before a wall can be dense-packed. The free assessment confirms which of those apply to a specific house.
Usually, yes. Norfolk's suburban building has continued for decades since the major growth recorded in the Pondville and Clark Streets section before 1940, and a lot of that later housing has attic insulation installed to the code minimum of the decade it was built, or fiberglass batts in the walls that have settled and left gaps over time. The scope looks different from a village-center job, but it is rarely nothing.
Norfolk is a short drive from our Franklin base, close enough that an assessment and an install day both fit comfortably into normal working hours without the travel time eating into the schedule. Exact timing depends on the scope, which the assessment sets before anything is booked.

The assessment is free, it accounts for whether your house is a village-center build or a later subdivision home, and it ends with a written scope before anything is scheduled.
