The insulation contractor based right here in Franklin
Complete Home Comfort is headquartered in Franklin, Massachusetts, at 1000 Chestnut Street. That is not a marketing line, it is the town where the crew and the trucks are based, inside a service area that reaches twenty towns across four Massachusetts counties, in the same town that is home to Dean College and the first public library in the United States.

What a Franklin address means for the schedule
An insulation contractor whose office sits inside the county it covers runs a shorter morning than one dispatching from outside the area. Complete Home Comfort's crew starts each working day from 1000 Chestnut Street, Monday through Friday, 7:30am to 4pm, closed Saturday and Sunday, which means a Franklin job is never squeezed onto the far end of a route that started somewhere else.
That matters most on the two visits every insulation job needs: the assessment that maps the scope, and the install day that carries it out. A crew based in Franklin reaches a Franklin address faster than it reaches a job in Foxborough or Milford, and a quick follow-up visit is easier to schedule when the drive back is short. The company's Norfolk County coverage runs from Franklin out to Bellingham, Medway, Millis, Norfolk, Wrentham, Walpole, Medfield, Dover, Norwood, Needham, Dedham, and Foxborough, with Franklin sitting at the middle of that map rather than the edge of it.
Four eras, four different insulation problems
Franklin's houses split roughly into four ages, and each one showed up on the map for a different reason. The colonial and federal-era houses ring the town Common, which took its triangular shape in the mid-1700s. The worker housing filled in around the mill villages of Unionville, City Mills, and Rivers End as the town's straw-braiding and woolen-mill industries expanded through the 1800s and into the 1920s. The capes and ranches came next, built through the town's school-building and housing-authority years in the 1940s, 50s, and 60s. Newer subdivisions have kept going up since, as Franklin's population climbed past 33,000 at the 2020 census and toward nearly 37,000 by 2022. Pick an era below to see what it usually means for a scope of work.
Housing-era selector, pick when the house was likely built
Common-era and colonial housing, pre-1850
These are Franklin's oldest houses, many standing near the town Common that took shape in the mid-1700s. Wall cavities are typically empty behind old plaster and lath, framed with the open balloon framing common before the 1930s, and the foundation underneath is often fieldstone or rubble rather than poured concrete.
What fixes each of those problems
Every one of those four eras gets the same first step: air sealing before insulation goes in, because pumping loose material into a leaky cavity does not stop the air movement doing most of the damage. Past that first step, the right material changes with the house.
For the Common-era houses and the mill-village stock around Unionville, City Mills, and Rivers End, the open balloon-framed wall cavities get dense-pack cellulose, drilled and filled bay by bay rather than blown loose across a floor. Where the foundation underneath is fieldstone or rubble instead of poured concrete, which is common on Franklin's oldest houses and on older houses in the towns around it, the rim joist gets rigid foam or closed-cell spray foam cut and sealed against an irregular sill rather than laid flat the way it would over a smoother modern foundation.
For the capes and ranches from Franklin's 1940s, 50s, and 60s building years, the knee walls and sloped ceilings a cape's roofline creates get insulated to close off those small triangular spaces, and the attic floor gets topped up with blown cellulose over whatever thin batt the house was built with.
For newer construction, the scope is usually smaller but not skipped: sealing the rim joist band and the attic hatch, then topping up an attic that met the energy code the day it was built but has since settled and compressed, which happens to any attic batt after enough years.
How a Franklin job runs, start to finish
Assess the house
The crew walks the attic, the walls, the rim joist, and the basement or crawl space, and checks the house's construction era against what is actually behind the plaster or drywall before anything is quoted.
Write the scope and the paperwork
The findings are written up, and where the house qualifies, the paperwork is sent to the utility program for approval before a crew is scheduled to come back and do the work.
Air seal first
Gaps at the rim joist, the attic hatch, and any wall penetrations get closed before insulation goes in, on every job, regardless of the house's age.
Insulate to the scope
Material is matched to the zone and the era identified in the assessment, whether that means a dense-pack wall cavity, a rim joist band, a knee wall, or an attic top-up.
Walk it with the homeowner
Every area in the scope gets checked before the crew leaves, and because the crew is based in Franklin, a short follow-up visit is never a long drive away.
The Mass Save incentive and the license behind the work
Through the Mass Save Home Energy Services program, eligible Franklin households can receive incentives covering up to 75 percent of qualifying insulation upgrades. A free home energy assessment maps the house's construction era and the actual scope needed before that paperwork is written, so the number submitted to the program reflects the house rather than an estimate.
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. Both are named here because a homeowner asking a Franklin contractor to work on a fieldstone foundation or a balloon-framed wall cavity is entitled to know who is licensed to do it.
The services this housing stock actually needs
Given the four eras above, four services carry most of the weight on a Franklin house, and all four sit under the same insulation services the company builds every scope from.
Air sealing
The step that comes before every other one, on the balloon-framed cavities of Franklin's oldest houses and the settled gaps of its newest.
Air sealingAttic insulation
The most common single fix on the town's capes, ranches, and newer construction, where the attic floor rarely got touched after the original build.
Attic insulationWall insulation
Dense-pack cellulose for the empty balloon-framed cavities behind the plaster in Franklin's Common-era and mill-village houses.
Wall insulationBasement insulation
Rim joist and fieldstone foundation work, common on the older housing stock in the villages that grew up around Franklin's 19th-century mills.
Basement insulationFrequently asked questions
The company is headquartered at 1000 Chestnut Street in Franklin, and the crew starts each working day from there, Monday through Friday, 7:30am to 4pm. It is the town at the center of a twenty-town service area, not a mailing address chosen for the map.
Yes. A fieldstone or rubble foundation, common on Franklin's oldest houses, takes rigid foam or spray foam differently than a smooth poured wall, since the material has to be cut and sealed against an irregular sill rather than run flat. The assessment maps the actual foundation before any scope is written.
A cape built in Franklin's postwar building years usually has knee walls and sloped ceilings that need their own insulation, plus an attic floor that carries whatever thin batt the house was built with. A newer subdivision house met the energy code the day it was built, so the scope is usually smaller, limited to sealing and topping up rather than starting from an empty cavity.
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.
