Injection foam wall insulation · Whitewater, WI

Whitewater’s old houses are charming. The heating bills aren’t.

The Victorian and pre-war homes near campus and downtown, the 1950s–70s ranches on the north side, the lake homes toward Whitewater Lake — most have empty or settled walls. Cozy Walls fills them with injection foam from the outside, in a day or two, without touching a wall in your living space.

Erik is a UW–Whitewater grad and lives twenty minutes away.

Why Whitewater walls run cold

  • Pre-war homes near downtown and campus: plaster and lath, an empty cavity, and original siding. They were built to be repaired forever — not to hold heat.
  • Post-war ranches: either nothing in the walls or cellulose that packed down and left the top of every stud bay open.
  • Rental and multi-unit homes: if you own one, empty walls are why the furnace bills eat the rent. Foam is a one-time fix that transfers with the property.
