Wall Insulation in Mukwonago, Wisconsin
Village homes, farmhouses, and lake places — and winters
that find every empty wall.
From the old village core to the farmhouses on the edge of town to Phantom Lake,
Mukwonago’s housing has one thing in common: walls that were never insulated for
what Wisconsin actually does in January.

- MUKWONAGO’S HOUSING PROBLEM
Three kinds of Mukwonago homes. One shared secret behind the siding.
The village core has homes going back a century — built solid, built before insulated
walls were a thing. Outside town, the farmhouses are older still: balloon-framed, drafty
by design, with wall cavities that run open from sill to attic and pull cold air the entire
way. And the subdivisions that grew through the ’80s and ’90s got the insulation of their
decade — which has spent thirty-plus years settling and gapping.
If any of those is your house:
- 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 out here, the wind doesn’t help
- The old farmhouse kitchen or back bedroom is unusable in deep winter
- 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 Mukwonago 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. In balloon-framed farmhouses, filling the cavity also blocks the top-to-bottom air rush those walls were built with.
- 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%.

- WHY YOUR NEIGHBORS PICK US
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 up the road 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.

- MUKWONAGO FAQ
Local questions, straight answers
Do you charge a trip fee to come out to Mukwonago?
Never. Estimates are free, and
there’s no travel charge.
Our farmhouse is balloon-framed — people keep telling us it can’t be insulated without gutting it. True?
Not true. Balloon framing is actually a strong candidate for
injection foam: the foam fills the open cavity and stops the sill-to-attic air rush that
makes those houses so brutal in winter — all from the outside, no gutting.
We’re on well water with pipes in an exterior wall. Winter is nerve-wracking. Will this help?
That’s exactly the freeze-risk scenario foam attacks: it fills the cavity around
those lines and shuts off the cold-air infiltration that causes most freezes.
Will you handle the Focus on Energy paperwork?
Every page of it. You just cash the
check.
