Wall spray foam insulation in Stony Plain runs into something unusual: this is a town that has spent decades painting murals across its downtown walls, and a place that treats the outside of its buildings as worth looking at is a place where exterior alteration is a bigger decision than elsewhere.
Where the outside of the building is not available
On the painted downtown buildings the exterior is not a surface anybody is going to strip, re-clad or insulate from outside, and that is the correct answer rather than an obstacle. It also settles the method: everything done to those walls is done from the inside, working with whatever the existing assembly turns out to be, and the sprayed layer suits that because it will follow an irregular masonry or plank face that no rigid board will sit against. The same logic applies to any building in this town whose frontage somebody cares about.
On a house, the wall is still rarely where the money should go
Away from the painted walls the ordinary rule holds. A household ringing about walls has usually identified the surface they can touch rather than the one that is losing the heat, and on most houses here the ceiling plane, the rim joist and the junctions between the original building and its additions are all doing more damage. Saying so loses a larger job and it is the honest answer, and on an older Stony Plain house those junctions are numerous enough to keep a budget busy.
Doing a wall from inside means opening a room
It follows from the first section and it is the part people underestimate. Where the exterior is not available, the only route to the wall is through the finished face, which means the room comes apart: skirting, casings, outlets, whatever is fixed to the wall, and the drywall itself. The spraying is a short part of that. Most of the cost and nearly all of the disruption is in taking a room back to the studs and putting it together again afterwards. That is why an interior wall job in Stony Plain is worth doing when a room is being renovated for other reasons and is rarely worth doing on its own, and it is why the honest question is what else you were planning to do to that room.
The old exterior wall that is now in the middle of the house
On any house here that has been extended, there is a wall that used to face outside and now has rooms on both sides of it. It still has its sheathing, frequently its original siding, and whatever insulation it had, and it is now a partition between two heated spaces where it is doing nothing useful. That is harmless in itself. What is not harmless is the junction where the addition meets it, top and bottom, because that joint runs from the foundation to the roof and was made by somebody working from outside a building that has since been built against. It is a common source of cold rooms in the older half of this town and it is almost never where anybody looks.
Wall Spray Foam Insulation Stony Plain: Common Questions
Can the front of our downtown building be done from outside? No, and it should not be. That work is done from the inside, which the sprayed layer suits.
Is drilling and filling worth it? Rarely here. The cavity is either obstructed or already full, and nothing gets sealed.
When is the wall genuinely worth doing? When the siding is coming off anyway. That is the moment, and it is worth planning for.
