Old Houses and Newer Ones Side by Side

Spray foam insulation in Lisbon covers homes from every era. 23.2% of Lisbon houses were built in 1939 or earlier, 17.2% in the 1970s, 17.3% in the 1990s and 16.7% from 2000 to 2009. The median year built is 1978.

Each age has its own problems

Pre-war houses tend to have empty walls and leaky attics. 1970s houses usually have shallow, settled attic insulation and bare rim joists. Homes from the 1990s and 2000s mostly need targeted sealing at the rim, the hatch and the garage. We quote what your house actually needs, not a package.

Lisbon Questions

What should I do first in a 1970s house?

Seal the attic floor, add blown-in to a useful depth, and foam the rim joist. Those three usually make the biggest difference for the money.

Can you tell how much insulation I have?

Yes. We measure the depth in the attic and identify the type, then estimate the R-value you have now.

Do you come out to Lisbon for small jobs?

Yes. Small jobs may hit a minimum charge, which we tell you up front.
