Spray Foam Insulation in Wyandotte, MI

Spray foam insulation in Wyandotte goes into a Downriver city with deep roots. Wikipedia notes Wyandotte built ships along its riverbank from the 1870s into the 1920s, including what Wikipedia calls the nation's earliest steel-hulled vessel, a tugboat built in 1873, and was a major toy-making center from the 1920s into the 1950s. Its 2020 population was 25,058, with 11,872 housing units, 5.2% vacant.

Older homes near the river

Many Wyandotte homes date from those industrial decades. They tend to have empty or thinly insulated walls, small attics and basements with bare rim joists. River wind adds to the air leakage.

What we usually do

Seal the attic floor and blow it to depth. Foam the rim joist with closed-cell. Dense-pack empty walls. Check basement walls for moisture before insulating them.

Code and rebates

Wayne County is in Climate Zone 5A in Michigan's energy code. DTE's 2026 page lists rebates by area for homes where DTE provides heat.

Balloon framing and open bays

Houses from Wyandotte's industrial era are often balloon framed. The stud bays run unbroken from the basement to the attic, so cold air rises through the walls like a chimney. We block those bays at the attic and basement, then fill the walls, which stops the draft and lets the wall insulation work.

Wiring and old materials

Old knob-and-tube wiring and loose-fill that could be vermiculite turn up in homes of this age. We flag them before any work, so they can be evaluated.

Upstairs rooms

Story-and-a-half homes here have the same upstairs issues found across older Downriver neighborhoods: kneewalls, slopes and side attics that leak. We seal the open floor bays first.
