Frequently Asked Questions

Going rates around Quinte sit near $1.75 to $3.50 a board foot for closed cell and $0.90 to $1.60 for open cell, where a board foot is one square foot at one inch deep. Area, inches, access and any tear-out decide the total. We visit and quote for free.

Closed cell sets hard, delivers around R-6 to R-7 an inch and blocks vapour once two inches are applied. Open cell stays soft, delivers around R-3.5 an inch, breathes and deadens sound. The first belongs on cold, damp surfaces; the second belongs inside the heated house.

Yes, anywhere people spend time. Ontario code calls for a protective layer, and half-inch gypsum is what most people use. Unoccupied spaces like attics and crawl spaces may use a tested coating. Your quote spells out which applies.

Yes, as long as water is not actively running through the wall. Closed cell spray foam insulation holds up to dampness and stops indoor air from condensing on the cold concrete. If there is a leak, it needs to be fixed by a waterproofing company first.

Yes. It is one of the best uses for it. Closed cell foam warms and dries the outside walls, and open cell foam between the floors cuts noise between the units. Belleville's 2025 zoning change has made basement apartments far more common, and we insulate many of them.

It works well in the attic, the basement, the rim joists and the knee walls of an old house. Solid brick walls need care, because the brick has to stay able to dry. We will tell you where foam belongs in your home and where it does not.

A basement or attic usually takes one day. Larger jobs or jobs that need old insulation removed can take two or three days. We give you the schedule in writing with your quote.

There is a smell while the foam is curing, which is why we ventilate the space and give you a re-entry time. A properly installed job should not smell after a day or two. A strong smell that lasts for weeks is a sign of bad foam and a reason to call.

Yes. We install all year. The surface has to be warm enough for the foam to bond, so we measure it and heat the space when needed.

Possibly. The provincial Home Renovation Savings Program pays on some insulation upgrades, usually after an energy advisor visits, and the rules depend on your heating fuel. Read the program's site before booking and let us know you are applying.

Yes. The business is fully insured, and the policy details are available when you book.

Each service page goes into more detail on cost, method and local conditions.

Attic rafters sealed in spray foam from the wall plate to the ridge

Attic Insulation

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.

Basement foundation walls covered in spray foam inside new framing

Basement Insulation

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.

Crawl space walls sealed in spray foam above a taped ground sheet

Crawl Space Insulation

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.

Older room with plank floors and walls re-insulated with spray foam
