Sunrooms, additions and closed-in porches are often the coldest rooms in a house, with three outside walls and a chilly floor. Home addition spray foam insulation brings the new room up to the comfort of the old one. Addition jobs are fully insured.
We insulate the walls, ceiling and floor of the addition while the framing is open, and we seal the joint where the new room meets the old house.
Where an addition meets the original house, there is almost always a gap. The old wall is not straight, the new framing does not match, and air finds a way through. Foam fills that seam completely.
Sunrooms are mostly glass, so the little wall and ceiling they have must work harder. Closed cell spray foam insulation packs the highest R-value into those shallow cavities, which makes the room usable in January.
Additions often rest on a slab or a short crawl space, and owners notice it through their feet. Closed cell goes on the crawl space walls and band joist, or under the floor itself. The crawl space insulation page walks through it.
Belleville's 2025 zoning change means some additions are being built as separate units. These need sound control between the units as well as warmth. Open cell foam between the units and closed cell on the outside walls covers both.
Phone (613) 912-7508 before the drywaller is booked and we will measure and price it on paper. Whole new houses are covered on new construction insulation, and the home page lists the rest. If the addition includes a new kitchen, see how we line up the work with cabinet painting crews.
One visit can price the whole house on a single written quote.
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.

Basement apartment spray foam insulation gives a second unit warm walls, a dry floor edge and a quieter ceiling. We install closed cell foam on the foundation and rim joists and open cell foam between the floors. Each job we do 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.

A new Belleville house only has one chance to be sealed properly, and it is before the drywall. New construction spray foam insulation fills the stud bays, corners and pipe holes while everything is exposed. We fit the builder's calendar, and new-build work is fully insured.

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.
