Garage spray foam insulation in St. Albert deals with buildings that are frequently in worse condition than their owners expect, and the reason is usually standing above them rather than anything about how they were built.
A building under the trees
A garage sitting under a mature canopy is shaded for most of the day, collects what the trees drop onto its roof, and stays damp for long stretches after any snow or rain. That produces moss on the shaded slope, soft trim, and sheathing that has been wet more often than it has been dry. None of that is an insulation problem, but it does have to be established before anything is sprayed, because foam applied against a wet or deteriorating structure hides a problem rather than solving it.
What that means for the order of work
On a St. Albert garage the sequence is frequently roof and trim first, envelope second. That is not what an owner expects to hear from an insulation contractor and it is the honest answer on a number of these buildings. Where the structure is sound, the work is straightforward and the building responds well. Where it is not, insulating it first simply means doing the job twice.
Detached, and sharing nothing with the house
In much of this city the garage is detached, set back on the lot and reached by its own path, so nothing is shared with the house at all. There is no comfort benefit indoors and no air quality argument to make. The entire case rests on what the owner wants to do in that building, and it is worth being direct about that, because for a building used only to park a car the honest answer is frequently that it is not worth insulating.
What it is actually being used for
Where it is worth doing, it is because the building has a second job. In a city with no industry, the garage is where the hobby lives: woodworking, restoration, bikes, a workbench that gets used on weekends through the winter. That is a real requirement and it is a different specification from storage, so establishing which one is wanted comes before a price rather than after it.
Garage Spray Foam Insulation St. Albert: The Covering Requirement
Foam in an attached garage does not stay exposed. The Alberta Building Code requires a thermal barrier over foam plastic in a St. Albert garage, normally drywall, and where there is living space on the other side of the wall that requirement is doing real work rather than being a formality. The drywall belongs in the quote from the first conversation, and a price that leaves it out is not a price for a finished job.
Garage Spray Foam Insulation St. Albert: Common Questions
Why is there moss on the garage roof? That is the canopy keeping it shaded and damp. It gets assessed before anything is sprayed inside.
Ours is detached. Is it worth doing? Only for what you use it for. Nothing is shared with the house, so there is no indoor benefit.
Does the foam need covering? In an attached garage, yes, normally drywall, and that belongs in the quote.
