Spray foam insulation cost in Stony Plain is priced by the board foot like anywhere else, and the spread between two quotes here is wider than in most towns for one reason: the two halves of this stock are not the same job.
Two stocks in one town produce two different quotes
On a post-1991 house the estimator can see what is there, the depth is calculable and the removal work is either none or a defined amount, so the number is firm. On a house that has been extended twice since 1955, the number depends on what is behind three different finishes, how many junctions there turn out to be, and what has to come out first. Both are honest quotes. They carry very different amounts of uncertainty and a household should expect that rather than assume the higher one is padded.
What the additions do to the arithmetic
Each addition brings its own band, its own junction with the original building and frequently its own foundation type, and every one of those is measured and priced separately because they are separate assemblies. That is why floor area is a poor guide to the cost on this stock. Two houses of identical size, one original and one that grew in three stages, are genuinely different jobs and the second is not being marked up.
Preparation is where two quotes on an older house diverge
Taking out settled batt, removing a stud wall standing off a foundation, dealing with a poly sheet stapled over cold concrete, protecting finishes somebody put in twenty years ago. None of that is foam and all of it is hours. A quote on an older Stony Plain house with no preparation line has not been thought about, and it is the line that turns a cheap number into an expensive job halfway through. Ask for it explicitly and compare that rather than the rate.
Interior-only work carries a cost the exterior route does not
This is the one line on a Stony Plain quote that would not appear in most towns. Where a building's frontage is painted or otherwise not available, the wall can only be reached from inside, and that means the room comes apart and goes back together around the spraying. The foam itself is a small part of that number. Skirting, casings, fixtures, the drywall and the making good afterwards are most of it, and none of that exists on a job done from the outside during a re-clad. It is worth understanding before comparing a quote here against one from somewhere the exterior was available, because the two are not measuring the same job.
Spray Foam Insulation Cost Stony Plain: Common Questions
Why is the quote on our house higher than our neighbour's? Usually additions. Each one brings its own band and its own junction, and they are priced separately.
Can you give a number over the phone? No. On an older house here more of the number is preparation than product.
What should we compare between two quotes? The preparation line first, and what surfaces each one says it is treating.
