Spray Foam Insulation in New London, WI

Spray foam insulation in New London is tied closely to the April 2026 flood. The National Weather Service lists a preliminary Wolf River crest of 12.12 feet at New London, above the 11.83-foot record from 1979. Evacuations lasted several days, and WBAY reported about 967 gas lines were shut off while residents sandbagged.

Wet insulation

Basements and crawl spaces that took on water may still have soaked insulation in rims, walls and floors. We remove it, allow the framing to dry and reinsulate with closed-cell foam, which does not absorb water.

Older homes, many rentals

New London sits on the Wolf and Embarrass rivers across Outagamie and Waupaca counties, and QuickFacts lists a 52% owner-occupied rate. Many houses are older and need attic sealing and rim joist foam on top of any flood cleanup.

Costs

HomeAdvisor lists removal at $1 to $2 per square foot, with removal plus replacement averaging about $1,852. HomeGuide puts rim joist foam at $2,000 to $2,500. Written estimates after a visit.

How we handle a flood-affected house

We locate every spot where insulation got wet, remove the soaked material, and give the framing time to dry. Any visible mold is pointed out so you can deal with it before insulation goes back. Below grade, we reinsulate with closed-cell foam on rims and walls. The attic is usually untouched by flood water and can be sealed and topped up at the same time if needed. Each step has its own line on the quote.
