A finished basement goes mouldy when warm room air touches cold concrete. Basement spray foam insulation sticks directly to the poured or block wall so that air never reaches it. Closed cell foam goes on the foundation, the rim joists and the slab edge, and each basement job is fully insured.
The problem with batts in a basement is simple. Warm, humid air moves through the fibreglass, hits the cold concrete and turns to water. The wood framing and the drywall soak it up, and the smell follows. Closed cell foam leaves no gap for that air to reach.
Belleville is built on heavily fractured limestone. Rain and snowmelt move down through the cracks in the rock and sit against the outside of the foundation for long stretches of the year. The wall stays cold and damp from the outside in.
Homes near the Moira River and the bay deal with high water in spring as well. The river has flooded parts of West Belleville and downtown many times, often because of ice jams. Closed cell spray foam insulation is not a waterproofing system, but it holds up when it gets wet, unlike batts that have to be torn out.
At two inches or more, closed cell foam stops water vapour on its own. That means no plastic sheet is needed in front of it. A plastic vapour barrier over batts in a basement often traps moisture on the wrong side and makes things worse.
We spray most basement walls at two to three inches. That gives R-12 to R-20 and room to frame in front of it for drywall and outlets.
Look up where the concrete stops and you will see the rim joist, the wooden band carrying the floor above. Older Belleville houses almost never have anything on it. Drafts slip in around it and frost and mould gather there. Every rim joist bay gets foam on a basement job.
Spray foam insulation does not stop running water. If water is coming through a crack or up through the floor, that needs to be fixed by a waterproofing company first. We will tell you if we see signs of a leak during the visit, and we will not spray over an active one.
Book through (613) 912-7508 or the form. Mention it if the basement is headed for a rental unit, since that changes the plan; our basement apartment insulation page explains why. Everything else we do is on the home page.

Warm air escaping upward is the main cost of a leaky Belleville attic. Attic spray foam insulation closes those openings, either across the ceiling or up on the roof boards, depending on what the attic is used for. Each attic job is fully insured.

Frozen pipes and icy floors usually trace back to the crawl space. Crawl space spray foam insulation goes on the foundation walls and rim joists, over a taped ground sheet, so the space holds close to house temperature. Insurance covers every crawl space we do.

Bedrooms over a garage are cold, and exhaust can drift in from below. Foam closes the shared wall, the ceiling and the outside walls of attached and detached garages alike. Garage work is fully insured.

A Victorian house loses most of its heat through the attic, the knee walls, the basement and the band joist. Century home spray foam insulation goes after those four places first and leaves the old brick alone. Work on heritage homes is fully insured.

Cold concrete, crawl space walls and the floor over a garage all call for closed cell spray foam insulation. It packs roughly R-6 to R-7 into each inch, stops air outright and stops vapour once two inches are on. Closed cell jobs are fully insured.

Noise through a ceiling or a bathroom wall is the usual reason to choose open cell spray foam insulation. It is light and springy, rates about R-3.5 to R-3.8 an inch, stops drafts and soaks up sound. Open cell work is fully insured.
