Crawl Space Spray Foam Insulation In Doon, Ontario

Backsplits And Sidesplits Often Have A Crawl Space

Pioneer Park grew in the 1970s with plenty of split-level homes. In a backsplit or sidesplit, part of the house often sits over a crawl space instead of a full basement. The family room or kitchen floor above it can stay cold all winter.

Crawl space spray foam insulation on the foundation and joist ends keeps that space close to the temperature of the rooms above.

Damp Crawl Spaces Cause Musty Smells

Cold, damp air in a crawl space rises into the house. It can carry musty odours and moisture that soaks into the floor framing. Fibreglass batts hung under the floor tend to drop and hold water.

We pull out loose batts, apply closed cell foam to the block or concrete and lay a heavy plastic ground cover taped at every edge.

Closed Cell Foam Is The Right Product Here

For crawl space spray foam insulation, closed cell foam is the only product we use. It resists water and controls vapour once it reaches about two inches. It also stiffens the wall and gives mice nothing soft to nest in. Open cell is never used in a crawl space because it can soak up moisture.

Access Changes The Price

A crawl space with two feet of headroom takes longer than one where you can kneel upright. We check the access and condition during the visit, and the price reflects what we find.
