- PEWAUKEE’S HOUSING PROBLEM
Pewaukee is two housing stocks — and one of them was never built for winter.
Along Pewaukee Lake and through the old village, you’ll find the original stock: lakefront
homes that started life as cottages, village houses that predate insulation codes
entirely, and decades of additions layered onto both. Those original walls are the coldest
surfaces in the house — many are empty.
Inland, the ranches and colonials that filled in through the ’70s, ’80s, and ’90s got
insulation — to the standard of their decade, which settled, gapped, and quit long ago.
Either way, the symptoms are the same:
- 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 — with the wind coming off the lake making it worse
- The oldest part of the house is a different climate from the rest
- Pipes on an exterior wall that freeze every cold snap
- 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
Most Pewaukee 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 dimesized 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. Our tests routinely measure at least 25% less air leakage — and up to 50%.

Owned by a neighbor, not a franchise.
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 minutes away 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.

- PEWAUKEE FAQ
Local questions, straight answers
Do you charge a trip fee to come out to Pewaukee?
Never — you’re minutes from our
Waukesha shop. Estimates are free, and there’s no travel charge.
Our lake house gets hammered by wind off the water. Does that change the job?
It
changes the payoff. Wind-driven air infiltration is exactly what a blower door measures
and exactly what foam shuts down — lakefront homes often show the most dramatic
before-and-after numbers we record.
The house has been added onto two or three times over the years. Can you handle that?
That’s most of the lake district. We thermal-scan every section, quote only the
walls that need foam, and fill each era of the house with the same complete, verified fill.
Will you handle the Focus on Energy paperwork?
Every page of it. You just cash the
check.
