Spray Foam Insulation in Algoma, WI

Spray foam insulation in the Town of Algoma covers newer homes and lake properties just west of Oshkosh. The town grew from 5,702 residents in 2000 to 6,866 in 2020, and water makes up about 21% of its 11.2 square miles along Lake Butte des Morts. It was established in 1851 as Wolf River and renamed Algoma in 1871.

Newer homes

Homes built in recent decades usually need the rim joist foamed, the attic hatch sealed and any room over the garage fixed. Owners finishing basements should insulate walls before framing.

Clay soil near the lake

Like most of Winnebago County, Algoma sits on clay-rich lake sediment that the state survey describes as relatively impermeable. Water lingers near foundations, so we check for seepage before insulating basement walls and use closed-cell foam below grade.

Wind off the water

Lakefront homes take more wind, which drives air through gaps. Air sealing the attic and rim makes a bigger difference than depth alone.

Costs

Rim joist foam is about $2,000 to $2,500 and closed-cell foam $3.00 to $5.00 per square foot by HomeGuide's figures. We price in writing after measuring.

A typical Algoma visit

We look at the basement first, checking for water marks along the foundation and measuring the rim joist, then the attic depth and hatch, then any rooms over the garage. On lakefront lots we also look closely at the side of the house facing the water, since it takes the most wind. The quote lists each area separately with material and R-value. Most jobs here take a day or two.
