Residential work in most Alberta towns means a detached house with four exterior walls, an attic and a basement, all of it belonging to the person who called. In Canmore that describes a minority of the housing. About 32% of homes here predate 1991, and the newer two thirds is overwhelmingly attached: duplexes, townhouse rows, stacked flats and multi-storey buildings on tight valley lots. The envelope is shared, and that reshapes the whole conversation.
Find out which surfaces are yours before anything else
In an attached building the cold surface you are complaining about may not be yours to alter. Party walls, the floor assembly between stacked units, the roof over the top floor and sometimes the exterior cladding itself can sit with the corporation rather than the owner. That is not an obstacle so much as the first step: establish which surfaces are inside your boundary, because it decides the scope, the approvals and the order of operations. We would rather raise that at the first visit than halfway through a job.
A shared envelope leaks in places a detached house does not
Attached construction introduces junctions that a standalone house simply does not have. The void inside a party wall often runs continuously from the foundation to the roof, which gives warm air a clear vertical path out of your unit. Demising walls meet the exterior wall at a corner that is hard to seal and usually was not. Shafts, chases and the gaps around plumbing that serves several units all connect spaces that were meant to be separate. Those paths carry heat, and they also carry sound and cooking smells, which is how most owners discover them.
Intermittent heating is normal here and it changes the risk
A large share of Canmore homes are not occupied continuously. They run on a setback through the week and come up to temperature on a Friday. Thermally that is fine. Hygrically it is not, because a shell that has been sitting cold for four days then receives a weekend of showers, cooking and drying ski gear all at once. The moisture goes looking for the coldest surface it can reach, and in a leaky assembly it finds one inside the wall. Air sealing is what prevents that, and it is why we push sealing ahead of depth on this stock.
Picking the right foam for a home rather than a building
Closed-cell at about R-6 to R-7 per inch is the choice against concrete, against the exposed walkout wall, at the rim joists and anywhere the cavity is too shallow to reach target R any other way; at roughly two inches it is also the vapour barrier. Open-cell at about R-3.5 to R-3.8 per inch is the better product where the objective is sound rather than heat, which in an attached Canmore home is frequently the actual complaint. Both are used in the same house, on different surfaces, for different reasons.
Where we usually start on a Canmore home
The rim joist bands, because there are several in a stepped or multi-storey unit and they are the cheapest real gain. The junction over a drive-under garage, because it separates a bedroom from an unheated space. Then the roof plane or vaulted ceiling, depending on whether there is an attic at all. Walls come later unless something is already being opened up. That order is not a preference - it follows where the air actually moves.

Residential Spray Foam Insulation Canmore: Common Questions
We are in a townhouse row. Can we do anything on our own? Usually yes, inside your own boundary. The first job is working out where that boundary runs.
The unit is empty midweek. Does that matter? It does. A shell that cools for days and then gets a weekend of moisture is where hidden condensation starts, and sealing is the defence.
Which product should we use? Closed-cell where moisture and shallow cavities are the issue, open-cell where sound is. Most homes here need both, in different places.
How much does residential spray foam insulation cost in Canmore? Priced per board foot of sprayed area, so the number follows area and target R-value. Access and staging in an attached building affect the schedule more than the rate.
How do I get a residential spray foam insulation quote in Canmore? Tell us whether the home is detached, attached or stacked, and which room is the problem. Those two answers set the whole scope.
