- Waukesha's Housing Problem
Waukesha homes are beautiful. Their walls are running on empty.
We know these houses because we live in them. The Victorians and craftsman homes around the historic downtown — many built before wall insulation was even a code requirement. The post-war ranches that filled in the neighborhoods through the ’50s and ’60s — built fast for growing families, with walls that were lucky to get a thin batt. The ’70s subdivisions — insulated to standards we’d laugh at today.
If your Waukesha home was built before 1990, odds are your walls are under-insulated, settled, or flat-out empty. You already know the symptoms:
- The A/C runs all day in July and the house still won't drop below 79
- The furnace can't hold 65 on a January night — and it never shuts off trying
- One room off the thermostat's path is always the wrong temperature
- Bathroom or kitchen pipes on an exterior wall that freeze every cold snap — the ones you leave dripping all January
- Frost on the inside of the walls on the coldest mornings
Your walls are the biggest surface of your home. We fix that — and prove it — in a day or two.
- How It Works
Four steps. Most Waukesha homes: done in one day; two-story or 1,400+ sq ft: two.
- 01 — MEASURE
Measure
Blower door test first — a hard number on how much air your home leaks. Thermal imaging shows exactly where.
- 02 — ACCESS
Access
A course of siding comes off — or dime-sized holes through mortar joints on brick homes. Nothing gets torn open.
- 03 — FILL
Fill
Injection foam fills every cavity completely and cures in place — it never settles or sags.
- 04 — PROVE IT
Prove It
Siding back on, final thermal scan, and a second blower door test. Before and after, side by side.

- Why Your Neighbors Pick Us
The insulation company that's actually FROM here.
Cozy Walls is owned by Erik Hoffman — a retired Army Master Sergeant with 29 years of service, a standard of strict attention to detail, and a shop right here in Waukesha. Our crew has insulated over 200 Wisconsin homes, and when you call for an estimate, the person at your door is Erik — the owner, not a salesman.
Every job is backed by our Lifetime-of-the-Home, Transferable Warranty — the foam is warranted never to settle, sag, or lose performance for as long as your house stands, and it transfers to the next owner if you sell.

Local questions, straight answers
Do you charge a trip fee to come out in Waukesha?
Never — you’re in our backyard. Estimates are free, and there’s no travel charge anywhere in Waukesha County.
My house is one of the older homes near downtown — plaster walls, original siding. Can you still do it?
Yes. Older Waukesha homes are our bread and butter. Wood siding comes off and goes back on cleanly, masonry gets dime-sized holes through the mortar joints, and plaster interiors can be drilled and rough-patched from inside if you prefer we never touch the exterior.
How fast can you get to me?
Your estimate happens fast — we’re based in Waukesha, so Erik can usually be at your door within days. Install dates depend on the season and the schedule; we’ll give you a straight answer on timing when we quote, and once your day comes, most homes are finished in that single day — two-story homes or anything over 1,400 sq ft take two.
Will you handle the Focus on Energy paperwork?
Every page of it. You just cash the check.
