Injection foam wall insulation · Wauwatosa, WI

Wauwatosa homes have character. Most of them have empty walls.

The 1920s and ’30s homes around the Village and Washington Highlands, the brick bungalows, the post-war Cape Cods and ranches farther west — many have little or nothing in the walls. Cozy Walls fills them with injection foam from the outside, in a day or two, without touching the plaster in your living space.

Erik, the owner, does every Wauwatosa estimate himself.

Why Wauwatosa houses lose so much heat

It’s the era, not the builder. Much of Wauwatosa’s housing went up before insulated walls were standard, and the plaster and woodwork that make these homes special are exactly what you don’t want torn out to insulate them.

1920s–40s homes near the Village and the Highlands: plaster over lath, brick or siding outside, and an empty cavity in between.
Brick bungalows and Tudors: we drill through the mortar joints, fill the walls, and patch the mortar to match.
1950s–60s Cape Cods and ranches: empty walls, or fiberglass batts we can usually fill around. Loose blown-in insulation we check for at the estimate, because foam can’t flow through it.

The result: a furnace that runs all winter and a house that still feels drafty.

What we do in Wauwatosa

Whole-home wall insulation

Every exterior wall filled with injection foam from the outside. Most homes in one day; two-story or over 1,400 sq ft in two.

The one room that never warms up

Usually an open rim joist or an empty exterior wall. We seal the rim joist and fill the walls around it.

Rim joist and basement walls

The leakiest spots in an older Wauwatosa basement, sealed with foam. Standard rim joist sealing is a flat $2,500, or $2,000 with a wall job.

Proof, not promises

Blower-door test and thermal scan before and after on every whole-home job.

What it costs in Wauwatosa

Insulate all of your exterior walls for as little as a $5,000 service (based on square footage) — that’s $3,575 net after the $1,425 Focus on Energy rebate check* that we file for you. Military ($750**), first responder, teacher, and 60+ ($500**) discounts apply on whole-home projects. Show us a lower written quote for the same scope and we’ll beat it by $500. Erik gives you the number in writing at the estimate, and it’s good for 30 days.

*Focus on Energy is a Wisconsin program. Rebates are not available on Illinois homes.

**Discounts apply to whole-home projects with a minimum job size of $5,000. One discount per household.
