Residential spray foam insulation in Blackfalds covers the whole house rather than one assembly. On this stock the survey is quick, because the buildings are consistent, and the findings are consistent with them.
What the builder did well, and what nobody asked for
It is worth being fair before listing problems. A house built here in the last twenty years has a properly insulated attic to a specified depth, insulated walls, modern windows and a sealed vapour control on the warm side. That is a real standard and it is why these houses are comfortable. What nobody was asked for was continuity: the joints between assemblies, the penetrations added by other trades, and the band where the floor structure lands on the foundation. Those were not specified, not measured and not inspected.
The four places a young house leaks
They are the same four almost every time. The rim joist around the perimeter of the basement. The ceiling plane where fixtures, fans and stacks pass through it. The floor and side walls of any room over an attached garage. And the junction where a bonus structure or a cantilever meets the main building. Treat those four and the house changes. Add depth anywhere without treating them and it generally does not. It is worth walking a Blackfalds house with that list in hand rather than asking for a general assessment, because the general assessment tends to produce a general quote.
Doing it while the basement is still open
A large share of these basements are undeveloped, and that is the cheapest access anybody will ever get to the most valuable item on the list. Every joist bay is visible, nothing has to come out, and the work is finished in part of a day. Once a ceiling is in, the same work means opening what was just built. Anybody in this town planning to develop a basement should treat the band as part of that project.
What a whole-house visit actually finds
Usually less than the caller feared. The assemblies are sound, the material is where it should be, and the problem is three or four specific junctions rather than a building that needs redoing. That is a better outcome than an older house and it is worth saying at the start, because people who have read about older-home retrofits arrive expecting a much larger project than their house needs. The work here is narrow, it finishes quickly, and the difference is felt through the first winter after it rather than gradually.
Residential Spray Foam Insulation Blackfalds: Common Questions
Is our whole house going to need doing? Very unlikely. On this stock it is usually three or four specific junctions.
What are the four places? The rim joist, the ceiling penetrations, the floor over the garage, and any cantilever or bonus structure.
When should we do it? Before a basement is developed. That access does not come back once a ceiling is in.
