A Fast-Growing City With Young Homes

Spray foam insulation in Marion is often a finishing job for newer houses. Marion grew from 26,294 residents in 2000 to 41,535 in 2020, and its housing units went from 10,968 to 17,810. The median home was built in 1994, and 41.5% were built in 2000 or later.

What younger homes need

Newer Marion homes usually have a decent attic, but the same weak spots show up again and again: bare or batt-filled rim joists, cold floors over garages, leaky attic hatches and recessed lights in the top-floor ceiling. Closed-cell foam handles the rim and garage floors. Attic sealing and a top-up of blown-in handles the rest.

Finishing basements

With 77.4% of homes owner-occupied and a median value of $241,700, a lot of Marion owners invest in their houses, and finishing the basement is high on the list. Foam on the foundation walls and rim joist before framing makes the finished space warmer and keeps moisture off the concrete.

Snow and cold

NOAA's 1991 to 2020 normals list about 34.3 inches of snow a year in Marion and a record low of -33°F, set in January. Ice dams on the eaves after a heavy snow are a sign the attic is losing heat.

Marion Questions

We get ice dams every winter. What fixes that?

Sealing the attic floor so warm air stays out of the attic, adding insulation depth and making sure the soffit vents are open. Insulation alone without sealing often does not solve it.

Is foam needed behind a finished basement wall?

It is one of the best options. Closed-cell foam gives an air seal, moisture control and R-value in one layer. Foam board with sealed seams can also work.

How long does a rim joist job take in a Marion house?

Most are done in a few hours to a day, depending on access and the size of the basement.
