Residential spray foam insulation in Ponoka covers the whole house rather than one assembly: the foundation, the band, the ceiling plane, and anything with a shallow roof over it. The first task on one of these visits is working out which house you are actually standing in.
A stock that spans a century on streets that look alike
Ponoka has been here a long time and it has grown steadily rather than in one wave, so a single street can hold a pre-war house, a post-war bungalow, a seventies split and something built last decade. They have similar frontages and completely different assemblies behind them. That is why age is asked before anything else, and why a quote given without establishing it is a guess dressed up as a number.
What each era of this stock actually needs
It is predictable once the age is known. The oldest houses need sealing far more than depth, and they frequently need the water dealt with before anything else. The post-war and seventies stock needs the band, the ceiling plane and usually an addition with a shallow roof over it. The newest houses need the band and the penetrations, because depth was specified and inspected and sealing was not. Three different jobs, one street.
The addition that every generation added
Almost every older house in this town has grown at least once, and each addition brought its own foundation, its own band and its own junction with the original building. Those junctions are the least likely part of any house to have been sealed by anybody, and they are where the cold rooms almost always turn out to be. Finding them is most of what a proper survey does on a Ponoka house, and it is the reason a walk round the outside tells you more about where to look than any conversation about the heating does.
Sequence, because doing it in the wrong order wastes money
Water and drainage first, because sealing a wall that is still taking water hides a problem behind a finished room. Then the band. Then the ceiling plane and its penetrations. Then depth, and then any shallow-roof assembly. Done in that order a modest budget changes how the house behaves. Done in reverse a larger one frequently does not, and that is the single most common way money gets wasted on an older house.
