Residential spray foam insulation in Carstairs is bought by households who are out of the building for most of the hours it is coldest, and that changes both what should be done and the order it should be done in.
What a thermostat schedule is actually asking the building to do
A setback schedule asks a house to fall four or five degrees, hold there unattended for ten hours, and then come back up inside about ninety minutes. That is a demand on the envelope rather than on the furnace, and it is a harder one than holding a steady temperature. Insulation depth governs how slowly the building falls. Air leakage governs how quickly it comes back, because a leaky building spends the recovery heating air that is already on its way out. Almost every complaint in a Carstairs house is about the second of those, and almost every quote people are given addresses the first.
Where the two stocks each give it up
In the pre-corridor houses the losses are the ordinary ones of their age: an attic that was topped up but never sealed, a rim joist with nothing in it, an addition whose junction with the original building was never closed. In the newer subdivisions the shell is generally sound and the losses concentrate at a small number of built-in details, the same ones on street after street because one crew built the phase. Knowing which of the two a house is saves an entire round of guessing, and it is settled by the build date rather than by looking at the outside.
Doing the work while nobody is in the building
This is the one genuine advantage of a commuter town and almost nobody uses it. A crew can be in an empty house from eight until five without a household being displaced, without children or animals needing to be somewhere else, and without the awkward half-day where everyone sits in one room. Work that would be planned around a family in most towns can simply be done here. It is worth raising at booking because it can compress a job that would otherwise be staged over two visits into one, and the saving is in hours rather than in material.
When the answer is a smaller job than you came for
People frequently ring about the walls, because the wall is what you can see and touch. On most Carstairs houses the wall is the last thing worth doing and the money goes considerably further at the ceiling plane, the rim joist and the junctions. Saying so costs a larger sale and it is still the right answer, because a house with sealed junctions and an untouched wall recovers faster in the evening than a house with a filled wall and everything else left as it was.
