What the day actually looks like
Real photos from Cozy Walls jobs in Southern Wisconsin this month. This is the whole process.
1. One row of siding comes off
We pop a single course of siding — no walls opened inside, no dust in your house.
2. Drill, fill, patch
Small holes in the sheathing, foam injected into every cavity, holes plugged. Most homes take one day; two-story homes or anything over 1,400 sq ft take two.
3. Siding goes back on
Same siding, same house. You would never know we were there.
4. Warmer that night
Whole-home jobs include a blower-door test and thermal scan so you can see the difference.

What your neighbors are saying
“I have an older home from the early 1900s. It was drafty and I could hear road noise in my living room — until Cozy Walls did their thing. The noise reduction was the first thing I noticed. Erik was very informative and the Veteran Discount helped a lot. Already noticing a difference in my energy bill.”

“We just bought our first house and our bedroom was very cold — the furnace ran constantly. Cozy Walls insulated the whole house and garage and found most of our walls had no insulation left. Now the bedroom is much warmer and the furnace runs a lot less, saving us money.”
