Injection foam wall insulation · Whitewater, WI
The Victorian and pre-war homes near campus and downtown, the 1950s–70s ranches on the north side, the lake homes toward Whitewater Lake — most 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 is a UW–Whitewater grad and lives twenty minutes away.
Every exterior wall filled from the outside. Most homes in one day; two-story or over 1,400 sq ft in two.
We drill from outside and patch to match. Plaster, trim, and woodwork inside are never touched.
Landlords: quieter units, lower utility bills, and a lifetime warranty that goes with the building.
Blower-door test and thermal scan before and after on every whole-home job.

As far as we open the house.

Every cavity filled top to bottom.

You’d never know we were there.
Insulate all of your exterior walls with financing from $99/month ($6,800 at 12.4% APR for 120 months = 120 payments of $99.14; rates and terms vary by credit approval) — and Focus on Energy rebates are available on qualifying projects,* with the paperwork filed 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.

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