Suburban Homes in Saginaw Township
Spray Foam Insulation in Saginaw Township covers the suburban side of the metro. Saginaw Charter Township had 41,679 residents in 2020, almost as many as the city next door. It actually predates its county: it was organized in 1831 as part of Oakland County and once covered all of today's Saginaw County. As Michigan made annexation harder after World War II and the city sold water to neighboring townships, new housing and businesses moved out here.
Housing from the 1950s forward
That history means most homes in the township are ranches, split-levels, colonials and newer two-stories built from the post-war decades on. They are generally tighter than lumber-era homes in the city, but they have their own weak spots: bare rim joists, thin attic insulation that was never upgraded, bonus rooms over garages and recessed lights.
Finishing basements
Many township homes have full basements, and finishing one is a good time to insulate. Closed-cell foam on the rim and walls before framing goes up keeps warm, damp air off cold concrete.
Flood risk near the river
In May 2020, when the Edenville and Sanford dams failed upstream, parts of Saginaw Township were among the areas evacuated. If your basement has taken on water before, closed-cell foam is the better choice because it does not soak up water.
What a quote looks like
Usually a line for the rim, a line for attic sealing and depth, and a line for any problem room. You choose what to do now.
Code levels for upgrades
Michigan's updated residential energy rules set R-60 for new ceilings in zones 5 through 7. Existing homes are not required to meet it, but it is a useful target when an attic is being redone, and ENERGY STAR recommends the same R-60 for an attic starting from nothing.

Saginaw Township Questions
Should I spray foam my basement before finishing it?
Yes, it is the easiest time. Foam on the rim and walls goes in before the framing.
My home is from the 1970s. Is the attic insulation enough?
Probably not by today's standards. ENERGY STAR recommends R-49 added over 3 to 4 inches of existing insulation in zone 5.
