Crawl space spray foam insulation in Taber is nearly always work under one part of a house rather than all of it, because on this stock the crawl space is under something that was added later and put on a shallow foundation rather than dug to full depth.
Most people find out they have one when something goes wrong in it
Nobody inspects a crawl space. It gets opened because a floor above it has gone cold, because something smells, or because a pipe let go and somebody had to get in there at short notice. That means the first look at one is almost always under pressure, in the middle of dealing with something else, which is the worst circumstance for making a decision about it. Getting a look at a Taber crawl space in a quiet month, with nothing wrong, is the cheapest thing available on this subject and almost nobody does it.
The one thing down there that will not wait for a quiet month
Everything else on this list can be scheduled. A water line running through a shallow unheated space cannot, because if it is at risk it is at risk now and the consequences of it letting go are not proportionate to the cost of dealing with it. Where a pipe runs through a Taber crawl space, where it sits relative to the insulation decides whether the household has a problem, and that gets looked at on the first visit regardless of what the enquiry was about.
Once it is closed up, nobody is going back in there
This is the sequencing point and it is worth more than it sounds. A crawl space that has been properly sealed is not a space anybody wants to reopen, so anything else that needs doing under that floor happens at the same time or it does not happen for a decade: a drain, a run of wiring, a shut off that should be reachable, a duct that was never connected. Making that list before the work starts costs an hour and it is the difference between a job that is finished and one that gets opened up again in three years.
Whether it is worth opening up at all
On some houses the answer is no, and it should be said. A crawl space that is dry, has no services in it, and sits under a room nobody uses is not where a limited budget goes, and there are two cheaper items on the same house that will do more. Where it is damp, where a pipe runs through it, or where the room above it is one the household actually uses, it moves up the list quickly. What decides it is what is down there rather than the fact that it exists.
Crawl Space Spray Foam Insulation Taber: The Covering Requirement
Where a crawl space is entered only to reach services the covering requirement is assessed on that basis, and where a Taber household is in and out of it for storage it is being used and the thermal barrier requirement follows. Settling which applies at the survey rather than afterwards is what keeps a covering from appearing later as a change to the price. More on thermal barrier vs ignition barrier.
Crawl Space Spray Foam Insulation Taber: Common Questions
Does it matter that only part of the house has one? That is the normal pattern here. It is under an addition rather than under the whole building.
Does it connect to the basement? Almost always, through a hole cut in what used to be an exterior wall. They get treated together.
What should be done if there is bare earth down there? Then that is the source, and covering the ground comes before anything overhead.
