Grandville's Post-War Housing

Spray Foam Insulation in Grandville mostly means houses from the second half of the 20th century. Grandville's population jumped from 2,022 in 1950 to 7,975 in 1960, and the median home was built in 1978 (ACS via Point2). Only about 7.5% of homes predate 1940. The city was settled in 1833 on the bend where the Grand River turns northwest toward Grand Haven and incorporated in 1933.

Typical work

Grandville ranches and split-levels from the 1950s to the 1970s often have thin attic insulation, open bypasses around chimneys and plumbing, and bare rim joists. Split-levels add a lower level partly below grade, where the rim and the half-height walls are often the coldest surfaces.

Near the river

The Grand River forms the city's northern border, and about 5.9% of Grandville's area is water. Houses on low ground near the river can have damp basements; we check for water before foaming a wall.

Permits through PCI

The City of Grandville sends building permit questions to its inspection provider, Professional Code Inspections. If your insulation is part of a remodel that needs a permit, we work to their inspections.

Ranch attics

A ranch has a big attic floor relative to the house, so that floor carries most of the heat loss. Many Grandville ranches have 4 to 6 inches of settled insulation. Sealing the bypasses and blowing to R-49 or more is usually the best value.

Erosion rules near water

For outdoor work near the river, the Kent County Road Commission enforces soil erosion control for Grandville and requires a permit within 500 feet of a lake or stream. Insulation work happens inside, so it rarely touches that rule, but it matters if you are also adding on.

Owner-occupied streets

About two-thirds of Grandville homes are owner-occupied and the housing count has been fairly stable, 6,276 units in 2010 and 6,835 in 2020, so most calls come from people improving a house they have owned for years.

Not until the water problem is fixed. We check walls and sills first.

The city uses Professional Code Inspections (PCI) for building permits.

Is blown-in or foam better for a Grandville ranch attic?
