Insulation Contractor in Natick, MA

Complete Home Comfort is an insulation contractor working in Natick, MA, dispatched from Franklin. Two houses on opposite sides of town can need completely different work here, so the walkthrough comes first and the number comes after it.

Assessment costs nothing Up to 75 percent covered Air sealing before insulation
CHARLES RIVER, SOUTH NATICK FRAMINGHAM / WORCESTER LINE Natick Center West Natick

The river runs past the old village in the south. The rail line and Route 9 run across the middle. Housing built along each one aged differently, and it shows up in the attic.

The two Naticks

Where the house sits changes the job

South Natick and the Route 9 corridor are the same town on paper and two different jobs in practice. Pick the one that sounds like your street.

South Natick and the older streets
The Route 9 corridor

Usual scope here: dense pack the open wall cavities, then seal and insulate the rim joist by hand where the sill sits on stone.

Usual scope here: seal the attic plane, top up the attic floor, and insulate the knee walls behind the upstairs rooms.

Village pattern

South Natick and the older streets

  • What is thereHouses built well before anyone put insulation in a wall, in the one village in town that still keeps its own mailing address.
  • Behind the plasterTall open wall cavities running floor to floor, with nothing in them and air moving through the whole height.
  • UnderneathFieldstone or rubble foundations more often than poured concrete, so the sill line is uneven.
  • What that costs youRooms that never hold heat evenly and a first floor that stays cold no matter what the thermostat says.
Corridor pattern

The Route 9 corridor

  • What is therePostwar capes and ranches in Sherwood, Pelham, Westfield and the Campanelli-built streets near Wethersfield, plus newer building that kept going after them.
  • Up topThin original attic batt that has settled and compressed, and knee walls behind the upstairs rooms that were often skipped.
  • UnderneathPoured concrete, which makes the rim joist straightforward to seal.
  • What that costs youUpstairs bedrooms that run hot in July and cold in January while the rest of the house is fine.
How a Natick job runs

Four steps, same order every time

Natick is one of twenty towns in the Middlesex County coverage area, and a job here is scheduled out of Franklin the same way every other one is.

01

Walk the house

Attic, walls, rim joist and basement or crawl space, so we know which of the two Natick patterns your house actually follows before anything is quoted. No charge for the visit.

02

Write the scope, file the paperwork

You see the scope in writing. Where the house qualifies, it goes to the utility program for approval before any material is ordered, which is the step that makes an incentive possible.

03

Seal, then insulate

Gaps at the rim joist, the attic hatch and every wall penetration get closed first. Packing material into a cavity that still leaks air hides the problem instead of fixing it.

04

Walk it again with you

Every area in the scope gets checked before the crew leaves, and anything that needs a second visit is booked out of the same office.

What it costs

Mass Save can cover most of it

Through the Mass Save Home Energy Services program, eligible Natick households can receive incentives covering up to 75 percent of qualifying insulation upgrades.

Program ceiling on qualifying work 75percent

That is a ceiling on eligible work, not a flat discount on every invoice. What your house qualifies for depends on the scope the free home energy assessment turns up.

Around town

Three parts of Natick, three different attics

Natick Center

Most of the center was rebuilt after the 1874 fire, so the housing around it is newer than the town's founding date suggests. Denser lots near the commuter rail stop, and party walls and shared rooflines that change how a scope is written.

South Natick

The oldest housing in town sits along the river here, low density and mostly predating cavity insulation entirely. This is where wall work and hand-sealed stone sills come up most often.

Around the lakes

Lake Cochituate and Dug Pond put close to 7 percent of the town under water. Neighborhoods near them hold a lot of former summer cottages converted to year-round use, which usually means an envelope that was never built for February.

Common questions

Natick questions we get asked

Natick is one of the twenty towns on the coverage list, and jobs here are scheduled the same way as jobs five minutes from the office. The crew is out this way most weeks.

Yes. A stone or rubble foundation takes a different approach than a poured one, cut and sealed against an uneven sill rather than run flat across it, and it takes longer. The assessment maps what is actually down there before the scope is written.

Usually, and on a cape or ranch off the corridor it is often the knee walls behind the upstairs rooms rather than the attic floor. Those little doors in the eaves open onto a space that is outside temperature, and the wall behind them is frequently bare.

No, and anyone who does is guessing. Two houses on the same Natick street can need very different work. The assessment costs nothing and comes back with a written scope and a real number.
