Garage spray foam insulation in Strathmore is nearly all attached-garage work, and the thing that makes it different here is that the largest opening in the house faces an open plain with nothing in front of it.
A big door with nothing in front of it
The overhead door is the biggest single surface on most of these houses and it is frequently on the windward side, because the street grid and the lots decided that rather than the weather. That means the door is not merely a poorly insulated area, it is a poorly insulated area under sustained pressure, and the gap around its perimeter is being actively driven rather than passively leaking. Dealing with the surround and the head is inexpensive against the rest of the building and it is the first thing worth doing on nearly every garage in this town.
The two surfaces that cost the household money
Only one wall of an attached garage is an exterior wall in the sense people think. The two that matter are the wall shared with the house and the ceiling under whatever room sits above, because those are boundaries between a heated room and a space that runs close to outside temperature for months. Almost every complaint about a cold room in a young house here traces back to one of those rather than to the room itself, which is why the work happens in the garage and the benefit shows up somewhere else.
Above freezing or comfortable, and they are not the same purchase
Households frequently ask for a warm garage and need a garage that does not go below freezing, and the two are separated by a large amount of money. Keeping a vehicle startable and nothing bursting is achievable with a sealed shell and very little heat. Working out there on a winter evening is a different specification with a different heater and a different envelope. Being asked which one is wanted, before anything is priced, is what stops people buying the second and needing the first.
What a winter of drifting does to the door seal
On an open lot with nothing upwind, snow does not fall onto a driveway so much as travel across it, and it packs against the first thing that stops it. On most Strathmore houses that is the overhead door. A drift banked against the bottom of it sits there for weeks, melts against the seal on a mild afternoon and freezes into it overnight, and by February the seal has been worked loose or torn. That is why the gap at the bottom of the door is routinely worse here in March than it was in November, and it is worth checking at the end of a winter rather than the start, because that is when it tells you the truth.
Garage Spray Foam Insulation Strathmore: The Covering Requirement
The wall and ceiling shared with the house are a required separation before they are insulation, so they are treated as one piece of work rather than insulation with a detail added afterwards. And where a Strathmore garage is finished or used as a workspace, the foam has to be covered with a thermal barrier, which belongs in the quote from the beginning rather than arriving later.

Garage Spray Foam Insulation Strathmore: Common Questions
Why is the room above the garage cold? That is the commonest call here, and the garage is where the work goes rather than the room.
Where do we start? The door surround and the head. On an open lot it is under real pressure rather than just leaking.
Do we need to heat it? Usually not. Above freezing is a much smaller purchase than comfortable, and it is often enough.
