The seasonal or second dwelling in this part of Alberta is not usually a lake cabin. It is the original farmhouse, still standing on the yard beside the house that replaced it, used for hired help through the busy months, for family at Christmas, and for storage the rest of the year. That is a particular kind of building with a particular set of problems.
A house being used at two extremes and not in between
The pattern is heavy occupancy during the growing and harvest months, when the weather is hot, and intermittent use in the cold months, when it may be heated for a week and then left. Almost nobody uses one of these buildings steadily. An envelope that only has to perform in a narrow band is a different brief from a house somebody lives in, and the two objectives — comfort in a hot month and protection in a cold one — pull in slightly different directions.
Why intermittent heating rewards sealing over depth
A building that is brought up to temperature and then allowed to drop does not benefit from depth the way a continuously heated one does. What it benefits from is a tight shell, because the rate at which it loses the heat you have just paid for is dominated by air movement rather than by conduction through the assembly. The practical consequence is that sealing the floor level, the ceiling plane and the window and door perimeters changes how one of these houses feels within an hour of the heat coming on, where adding depth in the attic alone would not.
Protection between visits is the real requirement
The thing that ruins one of these buildings is a frozen line while nobody is there. Winters here are variable rather than uniformly cold, which is what makes it dangerous: a mild stretch encourages leaving the heat low, and then a hard clear night arrives. The scope that matters is the perimeter at floor level, the crawl space or basement where the lines run, and any pipe in an exterior wall. That work is small, it is cheap relative to the rest of the house, and it is what we recommend doing first on a building used this way.
The summer half, when the crew is actually in it
Bow Island summers are long, bright and genuinely hot, and an old farmhouse with an uninsulated roof space and single-storey footprint gets uncomfortable in the afternoon. If people are sleeping in it during harvest, the ceiling plane is the item that decides whether the building is usable. Sealing and insulating the ceiling and dealing with the attic hatch is the whole job for that complaint, and it is the same work that helps when the building is heated in February.
Be honest about what the building is worth
Some of these houses are sound and worth a proper envelope. Others have had sixty years of deferred maintenance and the right answer is a limited scope: freeze protection, the ceiling, and nothing else. We would rather set that boundary with you at the start than produce a full-house quote for a building nobody intends to spend that on. The question to settle first is how many more years the building is expected to serve and in what role.
Closed up dry rather than closed up damp
One advantage this climate gives you is that a building left unoccupied here dries out rather than going musty, because the outdoor air is arid for most of the year. That makes an old second dwelling a better candidate for sealing than the same building would be somewhere wetter. It also means a little deliberate ventilation when the building is shut is usually enough, instead of the serious moisture management a closed-up cabin needs in a damp climate.

Cottage Spray Foam Insulation Bow Island: Common Questions
What should we do first on a building used only part of the year? The freeze protection and the air sealing, in that order. Depth matters least in a building that is heated intermittently.
Why does sealing matter more than insulation here? Because the loss from a building you have just warmed up is dominated by air leaving it. Insulation slows conduction; it does nothing about air movement.
Is it safe to shut the building up once it is sealed? In this climate, largely yes, with a little deliberate ventilation. Dry outdoor air is the advantage you have over a cabin in a wetter part of the country.
How much does cottage spray foam insulation cost in Bow Island? It depends entirely on scope, and on a building like this the scope is a decision rather than a given. A freeze-protection and ceiling package is a fraction of a whole-house job.
How do I choose a cottage spray foam contractor in Bow Island? Ask them what they would leave out. A contractor willing to limit the scope on an old second dwelling is reading the building the way you are.
