How Spray Foam Insulation Duluth Works

Spray Foam Insulation Duluth insulates and air seals homes, garages and shops in Duluth, Superior and the towns around the head of Lake Superior. We spray closed-cell and open-cell foam, blow in cellulose and fiberglass, dense-pack walls in older houses and remove insulation that is wet, matted or contaminated.

The Twin Ports have a lot of old houses. The City of Duluth's own housing market analysis put the share of homes built before 1940 at about 44 percent, several times the Minnesota average. Old houses are full of air leaks that newer construction never had: open chases, unsealed top plates, stone foundations and rim joists with nothing on them. That shapes how we work. We look for where the heat actually escapes before we decide what material goes where.

What a visit covers

We go into the attic and measure what is there. We look at the basement or crawl space, especially the rim joist where the house sits on the foundation. We check the walls if you are worried about cold rooms. We note signs of trouble such as frost on roofing nails, water stains, mold, rodent activity or old vermiculite, because those need to be dealt with before new insulation hides them.

How we work

• We see it before we price it. No quote over the phone for a house we have not looked at.
• Each area gets its own line. The quote names the material, depth or thickness, target R-value and price for every space.
• Air sealing comes first. Leaks get closed before insulation goes over them.
• We pick the material for the surface. Foam where it earns its cost, loose fill where it does the job for less.
• We plan around the weather. Foam has temperature limits, and Duluth winters are long. We schedule attic and outbuilding work for conditions the product can handle.
• Nothing changes without your OK. Changes to the scope are agreed in writing before the work changes.
