Two Kinds of Houses in One Small Town
Spray foam insulation in Ely covers both ends of the age range. About 15.3% of Ely's homes date to 1939 or earlier, while 28% were built between 2010 and 2019. The median year built is 2000. The town doubled from 1,149 residents in 2000 to 2,328 in 2020, and housing units rose from 434 to 866.
Older homes near the center
Ely was platted in June 1872 and named for John F. Ely, an officer of the Burlington, Cedar Rapids and Northern Railway. The oldest houses near the center of town often have little wall insulation and leaky attics. We start with sealing and depth in the attic and foam on the rim joist, then talk about the walls.
Newer homes on the edges
The new subdivisions are mostly family homes with basements and attached garages. In the 2020 census, 43.5% of households had children under 18 and the median age was 34.9. Finishing basements and warming bedrooms over garages are the projects we hear about most from homes like these.

Ely Questions
Our new house has a cold bedroom over the garage. Can you fix it?
Usually. We seal the band joist where the garage meets the house and fill the floor cavities. That is often a one-day job.
How do you insulate an old house without wrecking the walls?
Dense-pack cellulose through small holes, usually from outside. We patch and plug them afterward.
Do you charge extra to come to Ely?
No separate trip fee. Ely is well inside the area we cover.
