Spray Foam Insulation in Portland, MI

Spray Foam Insulation in Portland mostly means older homes. More than 38% of Portland's housing dates from 1939 or earlier, and the median home was built in 1957. The city sits where the Looking Glass River joins the Grand, earning the name City of Two Rivers, and grew after the railroad arrived in 1869. It became a village that year and a city a century later, in 1969.

What older Portland homes need

Pre-war houses here usually have open rim joists, thin attic fill, and walls with little or nothing in them. Working from the bottom up, we foam the rim, seal and insulate the attic floor, and then dense-pack the walls once the wiring has been checked.

River-town basements

With two rivers meeting downtown, basements on lower ground can be damp. We check for seepage, grading and downspouts before insulating any foundation wall, and recommend fixing water problems first.

Owners

About 71% of Portland's occupied homes are owner-occupied. The 2020 census counted 1,697 housing units, with just 4.4% vacant.

Farms and outbuildings

Portland sits in Ionia County farm country, and pole barns and shops are common around it. Closed-cell foam on the steel stops condensation and makes a building practical to heat.

Finished attics in old homes

Older Portland homes often have finished upstairs rooms with sloped ceilings and kneewalls. Foam in those spaces, or a sealed attic floor behind the kneewalls, makes the rooms usable in winter and summer.

Old railroad-era homes

Portland grew around its railroad, and many houses near downtown date to that era. Like other homes their age, they were built without wall insulation and often with balloon framing. Sealing those open wall channels at the attic floor and rim joist, then dense-packing the walls, is the core of most jobs here.
