Basement spray foam insulation seals and warms foundation walls in a single application, rough Galt fieldstone included. A clammy, cold cellar becomes a room you can actually use.
Every basement we spray is fully insured work. Expect roughly $3 to $5.50 per square foot of wall at Ontario rates, with your exact price written up after one visit.
Basement spray foam insulation suits a stone foundation better than anything else. Many older homes in Galt and Preston rest on fieldstone or rubble laid in soft lime mortar. That face is so irregular that boards and batts end up bridging over hollows.
Closed cell foam fills those hollows and the joints between stones. Air stops moving through the wall and, once the foam is thick enough, so does vapour. Before spraying, the wall is checked for running water. A stone wall that actually leaks needs that repair first, and you will hear about it plainly.
Newer basements in Blair, Silver Heights and Branchton are mostly poured concrete or concrete block. Foam handles either one, and flat walls go faster.
Today's Ontario code calls for much more basement wall insulation than older homes ever got. Closed cell foam reaches that level with a slimmer layer than batts, so a finished room keeps more of its floor.
Muggy August air touches a cool concrete or stone wall and drops its moisture right there. That is the source of the musty smell in so many cellars. Foam holds the inner face of the wall at room temperature, so condensation has no surface to form on.
Batts behind poly often lock that moisture in. Mouldy studs are a common find once an older finished basement gets opened up.
The rim joist is sealed during the same visit, since most basement drafts start there. Foam runs from slab to sill, around windows, pipes and ducts.
Exposed foam in a finished room must be covered, normally with drywall. If finishing is a future project, we explain what covering the space will need.
The best time for basement spray foam insulation is before framing and drywall go up. Bare walls let us reach every stone, every tie hole and every gap around the sill, and the foam can cure without anything in the way.
If you are planning a rec room, a home office or a basement apartment, book the spray date first and the framers second. Studs can then be set a little off the foam, which leaves room for wiring without cutting into the insulated layer. Closed cell foam at the right depth also means no separate plastic sheet behind the drywall, since the foam already controls vapour.
Basement spray foam usually takes a single day. The furnace and water heater are covered, the stairs are protected, and fans push air out through a window while we work. Foam goes up in thin lifts, and the depth is checked across each wall before we move on. Stay out for about a day, then the room is yours again, ready for framing.

Two services often share one trip, such as a foundation wall plus the rim joist above it.
Attic spray foam insulation keeps furnace heat from escaping through the ceiling and makes upstairs bedrooms bearable in summer and winter. Open attics, finished attics and sloped ceilings are all candidates for attic spray foam.

Crawl space spray foam takes the bite out of cold floors and keeps earthy, damp air below the house where it belongs. Additions, sunrooms, old summer kitchens and cottages often need it.

Commercial spray foam suits roof decks and walls in factories, warehouses, shops and offices, on steel, block or wood. It cuts heating losses and stops condensation in one application.

Metal building spray foam ends dripping steel and holds heat in workshops, machine sheds, quonset huts and steel garages. It bonds directly to the panels and closes every seam.

Garage spray foam heats up the cold bedroom over an attached garage and keeps exhaust fumes out of the house. Garages being turned into heated shops or home gyms get it too.

Wall spray foam fills opened stud cavities during a renovation and closes the cracks that let winter in. Plaster-and-lath houses, additions and new builds all benefit.

Rim joist spray foam seals the board capping the ends of the floor joists, which is the leakiest spot in most basements. The job is short and the difference is easy to feel.

Insulation removal clears out foam that smells, has shrunk or has peeled off the studs, so a new layer can bond to clean lumber or concrete. We also handle insulation removal for old batts and loose fill in attics.
