Coralville Homes Are Young, Not Perfect

Spray foam insulation in Coralville is mostly about tightening homes that are already fairly new. Coralville's median home was built in 1995. About 18.9% of houses date to the 1990s and 20.4% to 2010 through 2019. The city added more than 2,000 housing units between 2010 and 2020, growing from 8,310 to 10,408.

Where newer homes still lose heat

Builders meet code, but some spots are hard to get right on a busy site. The rim joist often has a batt pushed into each bay and nothing sealing the sill. Rooms over the garage can have gaps at the band joist and cold floors. Attic hatches and recessed lights leak. These are small areas, and closed-cell foam handles most of them in a day.

Basements

Many Coralville homes have full basements that get finished later. Foam on the concrete before the studs go up gives an air seal and moisture control behind the drywall. If you are planning a basement project, call us before framing so the timing works.

Near the river

The Coralville Dam, finished in 1958, has kept most floods in check, but the Iowa River still flooded in 1993 and again in 2008, when it passed the 1993 record at more than 31.5 feet. Homes in the lower parts of town that took on water may have insulation in the basement or crawl space that should be checked. We look for old water damage on the sill and rim before we cover anything.

Coralville Questions

My Coralville house is only 15 years old. Does it need foam?

Probably not everywhere. It may need sealing at the rim joist, the attic hatch, the floor over the garage or around recessed lights. We look first and only quote what will help.

We had water in the basement in 2008. Should the insulation come out?

If it got wet and was never replaced, yes. Wet batts lose R-value and can hold mold. We check the rim and sill for damage and quote removal and new insulation together.

Can you work around a finished basement?

Often we can reach the rim joist from a mechanical room or through a few drop-ceiling panels. If not, we tell you what access we would need before quoting.
