Crawl space spray foam insulation in Spruce Grove is not a common job inside the newer parts of the city, because houses built in the last few decades have full basements. Where it turns up is in the original town core, on the acreages in the county around it, and under additions built onto houses of any age.
Where the crawl spaces actually are
The older streets near the original centre carry houses that predate the era of a full excavation under everything, and out in the county there are farmhouses and acreage dwellings that were built on shallow foundations or piers. Those are the buildings with a genuine crawl space. Anywhere else in this city, a cold floor over what somebody assumes is a crawl space usually turns out to be an addition instead.
The addition is the commonest version of this call
A family room, a back extension or a converted porch added at some point was frequently built over a shallow void rather than tied into the basement, because that was the quick and inexpensive way to do it. That is why one room in an otherwise comfortable house has a cold floor and nothing else does, and it is why the work goes under that room rather than anywhere in the main house.
The only part of this anybody experiences is the floor above it
Nobody goes into their crawl space. The decision therefore gets made on a symptom two rooms away: a floor that is cold underfoot in one part of the house, a room that never comes up to the rest, a smell in the hall that arrives with the first cold week. Those are all real and they are all reporting the same thing, but they are indirect enough that owners spend money on the wrong end of the problem first. In a young Spruce Grove house the cause is rarely the floor covering or the furnace. It is a ventilated void under part of the footprint doing exactly what it was designed to do. Getting a look at the space before spending anything is the single most useful hour in the whole job.
Bringing it inside, with the ground dealt with first
The old approach was to vent one of these year round. In this climate that brings cold air in for five months and humid air in for three, which is the opposite of useful. The space gets sealed and brought inside the building envelope instead, and that begins with a sealed barrier over any exposed ground. Closing a Spruce Grove crawl space over bare earth without covering it produces damp rather than cold, and the order matters more than the product does.
Crawl Space Spray Foam Insulation Spruce Grove: Common Questions
Why does one room have cold floors when the rest of the house is fine? That room is almost always over an addition built on a shallow void rather than over the basement.
Is insulation between the joists already enough? With cold air moving below it, it does little, and against a damp floor structure it can do harm.
Do we need a ground cover? Yes, and it goes first. Sealing over bare earth turns a cold crawl space into a damp one.
Do you handle the covering as well? The requirement is identified and priced. Whether a Spruce Grove crawl space needs a thermal barrier or an ignition barrier is established before any work is booked.
