Quonset spray foam insulation in Didsbury is sprayed onto the inside of a corrugated arch, which is the only assembly that suits the shape, and on most yards around this town the arch is the building that has been put off longest.
The building that looks fine from outside, which is why it waits
An arch presents well from the driveway. The steel is painted, the shape hides nothing, and there is no sagging soffit or peeling trim to argue with. Everything that is wrong with it is on the inside face, where the water forms, and the only person who sees that is whoever is in there in February looking up. That is why the quonset is routinely the last building on a Didsbury yard to get attention despite being the one doing the most damage to what it holds. Nothing about the outside of one of these tells you whether it is worth doing. The inside face and the bottom edge do.
Mixed contents and no single temperature to aim at
The arch tends to become the building that holds whatever there is no room for elsewhere. A tractor, a set of tires, seed left over, a boat, the household overflow. That mixture is a genuine problem for specifying the work, because those things do not want the same conditions and some of them do not care at all. Steel and paint want the sweating to stop. Anything upholstered or paper-based wants stable humidity. Seed wants a stable temperature and dry air, and it is by some distance the fussiest thing in there. Sorting the contents into what actually needs protecting comes before deciding how far the envelope goes.
The concrete floor is why this building gets used for everything
Many older Didsbury yards have exactly one building with a poured floor, and it is the arch. That is why it fills up, and it is also the reason the envelope pays here. A slab holds temperature and will also carry moisture up out of the ground if the perimeter was never detailed, which shows on the bottom of the arch first. Where the floor is good, sealing the shell over it gives a genuinely stable space. Where the slab edge is wet, that gets addressed before anything is sprayed, because a sealed building sitting on a damp slab simply concentrates the water somewhere less obvious.
What the arch costs to leave alone for another five years
Deferring this is a defensible decision and it should be made with the number in front of you. The cost of waiting is not the price rise. It is the corrosion that continues on the inside face while the building keeps sweating, the condition of whatever is stored under it, and the fact that surface rust becoming structural rust moves the job from spraying to repairing. A shell in sound condition now is a straightforward job. The same shell after five more winters of dripping may not be worth spraying at all, and that is the honest thing to weigh rather than this year's quote against zero.
Quonset Spray Foam Insulation Didsbury: Common Questions
Can a quonset be failing when it looks fine from outside? They all do. The inside face and the bottom edge are what decide it.
Can we leave it another few years? Possibly, but the arch keeps corroding while it drips. That is what waiting actually costs.
How do you scope the job when everything is stored in the quonset? Then the first job is sorting what genuinely needs protecting, because that sets the scope.
