Injection foam wall insulation · Kenosha, WI

Kenosha winters come straight off the lake. Your walls should stop them.

The bungalows and two-flats around Uptown and Columbus Park, the older homes near Library Park, the post-war ranches farther west — a lot of Kenosha houses 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.

Why Kenosha houses lose so much heat

Two things work against older Kenosha homes. Much of the housing near the lake and downtown went up before insulated walls were standard, and the wind off Lake Michigan pushes cold air through every empty wall cavity.
  • Early-1900s homes near Library Park, Columbus Park and Uptown: plaster over lath, siding over sheathing, and an empty cavity in between.
  • Post-war ranches and Cape Cods: often built with nothing in the walls. 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 homes: the same empty cavity behind a heavier wall. We drill through the mortar joints from the outside and patch to match.
The result: a furnace that runs from December to March, and rooms that never feel warm once the wind picks up.

What we do in Kenosha

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 room over the garage

The cold bedroom or bonus room fixed by filling the walls around it and the garage below it.

Rim joist and basement walls

The leakiest spots in an older Kenosha basement, sealed with foam. Standard rim joist sealing is a flat $2,000.

Proof, not promises

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

What it costs in Kenosha

Most whole-home projects run $5,000–$12,000 depending on the size of the house, before 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.
