Spray Foam Insulation in Arlington, MA

Spray Foam Insulation in Arlington serves a dense residential town six miles northwest of Boston. Wikipedia lists 46,308 residents and 19,974 housing units at the 2020 census, a density of about 9,004 people per square mile. The town was settled in 1635 as Menotomy within Cambridge. Mill Brook once powered seven mills, and Spy Pond supported an ice industry until 1930. Today Arlington is mostly homes: Capes, Colonials, bungalows and two-families.

Capes and kneewalls

Arlington has many Capes and story-and-a-half houses. Their upstairs rooms have kneewalls with side attics behind them, often unsealed at the floor. Sealing those joist bays and insulating the kneewalls or the roofline is the most common fix for upstairs comfort.

Two-families

Arlington's two-families have the same issues as Boston's: a top unit under the roof, empty walls, porches tied into the frame and a bare rim joist. We plan them as whole buildings.

Near the water

Wikipedia notes Arlington borders the Mystic Lakes, the Mystic River and Alewife Brook, and contains Spy Pond, the Arlington Reservoir and Mill Brook. Homes on lower ground near those waters can have damp basements. Closed-cell foam on the rim helps with humid air, but water entry needs drainage work first.

Costs

HomeGuide lists air sealing at $350 to $3,000 and rim joist foam at $2,000 to $2,500 nationally. The written estimate is the price.

Checks first

We check for old wiring, vermiculite and leaks before planning.

Rooms over porches and garages

Arlington houses often have sunrooms over old porches or bedrooms over attached garages. Those floors sit on cold air and are usually under-insulated. Foam in the floor framing, plus sealing where the addition meets the house, makes them comfortable.
