Spray Foam Insulation in West Roxbury, MA

Spray Foam Insulation in West Roxbury is mostly about single-family homes. Wikipedia describes the neighborhood, in the southwest corner of Boston, as having some two-family houses but mostly single-family homes. Founded in 1630 as farmland within Roxbury, it broke away in 1851 and was annexed by Boston in 1874. Its homes went up as the West Roxbury branch of the Boston and Providence Railroad and later electric streetcars made commuting easy.

Typical houses

West Roxbury has Colonials, Capes, Tudors and bungalows from the early and middle 20th century, plus some older homes. Many have finished upper floors with kneewall attics, rooms over porches or garages, and basements with bare rim joists.

Capes and kneewalls

The Cape is one of the most common shapes here. Its upstairs bedrooms have short kneewalls with side attics behind them, often with the floor under those attics open to the rooms below. Sealing those joist bays and insulating the kneewalls or rooflines is the most effective fix for a hot-in-summer, cold-in-winter upstairs.

Attic floors

Where there is a walkable attic, sealing the floor and blowing loose fill toward the R-60 listed in the Massachusetts stretch code summary is the economical path.

Garages and porches

Rooms over garages and enclosed porches sit over cold air. Foam in those floor bays warms the room and, over a garage, blocks fumes.

Costs

HomeGuide lists typical attic insulation jobs at $1,000 to $2,700 and air sealing at $350 to $3,000 nationally. Your written estimate after the visit is the price.

Finished basements

Many West Roxbury owners have finished or plan to finish their basements. Before framing is the time to foam the rim joist and insulate the walls; the Massachusetts stretch code summary lists R-19 or R-15 continuous for basement walls in Zone 5. Closed-cell foam against the foundation keeps humid air off the cold wall behind new drywall.
