Key takeaways
- MetroWest has a wide mix: post-war capes and ranches, 1970s split-levels and large newer colonials.
- Older homes need attic, wall and basement insulation; newer homes often need air sealing and bonus room fixes.
- Rooms over garages and finished attics are common comfort complaints in larger homes.
- Most MetroWest towns are in Mass Save® sponsor territory, with a few exceptions.
The MetroWest housing mix
MetroWest stretches along Route 9 and the Mass Pike from Framingham and Natick out to Hopkinton, Southborough and Marlborough, with Sudbury, Ashland and Holliston in between. The homes reflect each era of suburban growth:
| Era | Common homes | Typical needs |
|---|---|---|
| 1940s to 1950s | Capes, small ranches | Knee walls, slopes, attics, empty walls |
| 1960s to 1970s | Split-levels, raised ranches, garrisons | Rim joists, overhangs, attics, lower levels |
| 1980s to 2000s | Large colonials with bonus rooms | Air sealing, rooms over garages, attic ducts |
| 2010s and newer | Code-built homes | Targeted air sealing, ventilation |
Older capes and ranches
Many neighborhoods in Framingham, Natick and Ashland have post-war capes and ranches with original insulation. Knee walls, slopes and empty walls are the main targets. See cape insulation and ranch insulation.
Larger newer colonials
In Hopkinton, Southborough, Sudbury and Holliston, many homes from the 1980s onward have decent insulation on paper, but:
- Bonus rooms over garages are cold in winter and hot in summer. See cold room above garage.
- Ducts in the attic lose heating and cooling. See duct sealing.
- Recessed lights and complex rooflines leak air into the attic.
- Finished basements may have fiberglass against concrete. See basement insulation.
Incentives
Most MetroWest towns are served by Mass Save® sponsors. Hudson and Wellesley, nearby, have municipal light plants. See who qualifies for Mass Save®.
New construction
Many MetroWest towns have adopted the Stretch Code, and builders need HERS ratings and blower door tests. BCI Group provides both, along with insulation. See new construction insulation.
"Our 1990s colonial has a cold bonus room and a hot second floor." The fix is usually air sealing the attic, filling the bonus room floor and sealing the knee walls.

Contemporaries and cathedral ceilings
MetroWest has many 1970s and 1980s contemporaries with cathedral ceilings, skylights and large windows. These homes often have thin roof insulation and many air leaks at skylights and ceiling fixtures. Roof deck improvements and careful air sealing address them.
Basements in newer homes
Many newer MetroWest homes have walk-out basements finished as living space. If foundation walls were finished with fiberglass against concrete, moisture and comfort issues can appear. Proper foam-based assemblies prevent these problems.
Heat pumps in MetroWest
Many MetroWest homeowners are adding heat pumps for cooling and heating. Homes with existing ducts in attics benefit from duct sealing or bringing ducts inside the envelope before connecting a ducted heat pump.
