Brookfield grew fast — and its walls show it.

Brookfield’s neighborhoods filled in through the ’60s, ’70s, and ‘80s: colonials, splitlevels, and sprawling ranches on generous lots. Solid houses, built well for their time — but “their time” insulated walls to standards we’d never accept today. Thin batts, gaps at every wire and pipe, and forty-plus years of settling.
The result is a house that looks like a million bucks and performs like a screen door:
Your walls are the biggest surface of your home. We fix that — and prove it — in a day or two.

Most Brookfield homes: done in one day; two-story or 1,400+ sq ft: two.

Measure

Blower door test first — a hard number on how much air your home leaks. Thermal imaging shows exactly where.

Access

A course of siding comes off — or dimesized holes through mortar joints on brick homes. Nothing gets torn open.

Fill

Injection foam fills every cavity completely and cures in place — it never settles or sags.

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 ten 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.

Local questions, straight answers

Do you charge a trip fee to come out to Brookfield?
Never — you’re ten minutes from our shop. Estimates are free, and there’s no travel charge.
We insulate twostory homes all the time. The upper walls take staging or a lift, and every cavity — both floors — gets filled and verified with thermal imaging. Two-story work is quoted accordingly, and usually takes two days.
That room is the classic Brookfield complaint — it usually has under-insulated walls on three sides. Foam-filling those walls is exactly the fix, and the thermal camera will show you the before and after.
Every page of it. You just cash the check.
