A building still open is the one chance to get the envelope right with everything reachable and nothing to dismantle first. The air barrier can be continuous by design instead of assembled from patches.
We work with builders and with owners running their own project, and we come in at the right point in the sequence rather than whenever a gap appears.

Part 9 residential work in this province moved to Tier 2 for permits received from 1 April 2026. The path runs on points, and a project needs ten.
Getting the building under 2.0 air changes an hour is worth 3.5 of them on its own, confirmed by a blower door test once the sealing and the openings are complete.
Foam is an air barrier from the moment it is installed, which is why it carries so much of that load within a single trade. Worth settling before the assemblies are locked in rather than afterwards.
The band at every floor level, which is the hardest place in the building to seal by any other means.
Below grade walls and slab perimeters, where vapour control has to come from the insulation itself.
Vaulted and cathedral ceilings, which have no depth for a vented assembly and no way back in once they are closed.
Bonus rooms, overhangs and any floor above unheated space.
Roofs complicated enough that venting them correctly is not realistic.
Foam everywhere is not automatically the best answer. A frequent arrangement lays a thin pass of closed cell right on the sheathing so it carries the air and vapour duty, then packs out the remaining depth with a cheaper material.
That buys a continuous air barrier where it counts and puts the rest of the budget into depth, which is where depth is what you actually need.
We set the options against the target rather than quoting the most expensive assembly by reflex.
Foam follows the mechanical and electrical rough-in and precedes the boarding. Get that order wrong and something ends up buried or something ends up cut back out again.
We take a slot in the programme, confirm the day before, and hand the space back trimmed flat and ready.
The sooner we see the drawings, the more we can do about the assemblies themselves rather than simply filling what has already been framed.

Cape Breton Spray Foam Insulation covers attics, foundations, crawl spaces, garages and new builds right across the island.
More heat leaves through the top of a house than through any other single surface, and the top of a house is also the cheapest place to intervene. Warm air rises, finds the openings around fixtures, hatches, plumbing stacks and wall plates, and departs.

Three separate problems meet in a basement. The wall touches wet ground, masonry moves heat readily, and the joint where framing lands on the foundation leaks air right around the building.
View Basement Insulation
Everything true of a foundation wall is true here, only on your elbows. Too little headroom, bare ground beneath, a difficult way in, and all of it directly under a floor people walk on.
View Crawl Space Insulation
The garage is the space people most want to be warmer and least often have treated properly. It is also the space whose insulation decides the comfort of a room you are already paying to heat, because whatever sits above it shares a floor with it.
View Garage Insulation
Two products share the name and they are not substitutes for one another. Getting that choice right is most of what separates a lasting installation from an expensive lesson.
View Closed Cell and Open Cell Spray Foam
Some insulation has to leave before anything else can begin. Saturated batts, contaminated loose fill, material rodents have been through, and foam that went on badly the first time.
