New foam will not stick to failed foam, soggy batts or dusty old loose fill. Insulation removal strips the space back to clean wood or concrete first, then new spray foam insulation goes on. We cut, bag and haul it all away, and removal work is fully insured.
New foam cannot be sprayed over failed foam or over dirty, damp insulation. It has to bond to clean wood or concrete to work.
Foam fails for three reasons: the two parts were out of balance, the surface was too cold, or one pass was laid on too thick. You will see gaps along the studs, crumbly or spongy patches, cracks, dark staining, or you will notice a sharp odour still hanging around weeks later.
The fix is to cut the bad foam out back to clean framing and spray it again properly. There is no shortcut.
Belleville has a long history of spring flooding along the Moira River, and basements anywhere in the city can take on water in a heavy thaw. Batts that get wet hold the water against the wall and start to grow mould. They have to come out. We remove them, let the wall dry and replace them with closed cell foam that holds up to dampness.
Old blown-in insulation in an attic often has dust, droppings and debris in it. Some very old attics have vermiculite, a grey-brown pebble-like material. Vermiculite can contain asbestos and must be tested and removed by an abatement contractor before we do anything in that attic. We will tell you if we see it.
Removing insulation takes time, bags and disposal fees. Cutting out failed spray foam is slow work. We price removal separately in the quote, so you can see exactly what it adds.
Call (613) 912-7508 or send photos through the form. We can often tell from a photo whether the foam has failed. For damp basements, see our basement insulation page. The home page explains every other service.

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.

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.

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.

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.
