Injection foam wall insulation · Menomonee Falls, WI

Menomonee Falls homes are solidly built. Most of them have empty walls.

The older homes near the historic downtown, the 1950s–70s ranches and Cape Cods that fill most of the village — 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 a wall in your living space.

Erik, the owner, does every Menomonee Falls estimate himself.

Why Menomonee Falls houses lose so much heat

It’s the era, not the builder. Most of Menomonee Falls grew fast after the war, and a lot of those homes went up before insulated walls were standard.

Older homes near downtown: plaster over lath, siding over sheathing, and an empty cavity in between.
1950s–70s ranches and Cape Cods: 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.
Brick and stone fronts: we drill through the mortar joints, fill the walls, and patch the mortar to match.

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

What we do in Menomonee Falls

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 a Menomonee Falls 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 Menomonee Falls

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.
