Spray Foam Insulation in Berlin, WI

Spray foam insulation in Berlin usually means upgrading older homes. The Fox River runs north to south through the center of the city, and from the 1860s to the 1990s fur and leather work earned it the nickname of the fur and leather city. Population has changed little in 70 years, from 4,693 in 1950 to 5,571 in 2020, so most houses are established ones.

What older homes need

Empty walls, thin attics and old foundations are typical. We seal and fill attics, foam rims and dense-pack walls where wiring allows.

Near the river

Homes on low ground near the Fox can have damp basements. We look for seepage before insulating walls below grade, and use closed-cell foam where it is dry enough.

Two counties

Most of Berlin is in Green Lake County, with a small part in Waushara County.

Costs

HomeGuide lists attic insulation at $1,000 to $2,700, rim joist foam at $2,000 to $2,500 and dense-pack at $1.60 to $4.20 per square foot. Written estimates after a visit.

Shops and farm buildings

The countryside around Berlin includes farms and rural homes with machine sheds and shops. Closed-cell foam on steel stops condensation, and thicker foam makes a heated shop practical. We quote outbuildings on the same visit as the house if you like, each with its own price and thickness listed.

What a visit looks like

We start in the basement, looking for moisture and measuring the rim joist, then check the attic. Older Berlin houses often have plaster walls and old wiring, so we inspect cavities before suggesting dense-pack. The written quote lists each area so you can choose what to do now and what can wait.
