Cold floors and drafts mean heat is getting out
In a Calgary winter, warm air finds every gap it can. The usual places are the rim joists along the top of the basement wall, garage ceilings under a bedroom, old walls with thin batts that have slumped, and the floor of a cabin or addition. You feel it as cold floors, rooms that never warm up and a furnace that keeps running.
BattsSpray foamSpray foam fills the gaps batts can’t
Spray foam goes on as a liquid and expands to fill the cavity, including the cracks and corners around pipes, wires and joists. Once it cures, it insulates and seals the air leak in one layer, so the space ends up air tight.
Two foam types
- Closed cell foam. Dense and rigid. Also blocks moisture, which makes it the usual choice for basements, rim joists, crawl spaces and anywhere that gets damp or very cold.
- Open cell foam. Softer and lighter. Good for interior walls and sound control where moisture isn’t the concern.
- “Isn’t spray foam expensive?”
- It costs more per square foot than batts. You also don’t pay to air seal separately, and it doesn’t settle over time. We price your actual job so you can compare. See what sets the price
- “Will it make a mess of my house?”
- Our reviews say the same thing over and over: on time and clean when we leave.
- “Do I have to move out?”
- You stay out of the sprayed area while the foam cures, and we tell you exactly when it’s safe to go back in before we start.
What sets the price of spray foam
Every job is priced on what we measure, not a flat rate. These are the things that move the number:
- How many square feet we’re spraying
- How thick the foam needs to be, and closed cell or open cell
- Access: open studs in a reno are faster than a finished crawl space
- Prep: old insulation that has to come out first
- Location in or around Calgary
Your estimate is free and written down, so you know the price before we start.

- Basement: rim joists and wall voids
Aztec did a great job of our basement. We had them spray our rim joists and wall/ceiling voids. They gave great guidance, were professional, on time, very clean, and a pleasure to work with.

Two brothers, one crew, your house
Aztec Spray Systems is run by two brothers. They came to Alberta, spent years spraying foam on job sites across the province, and started Aztec to do the work their own way.
You may not see our insulation, but you will feel the difference it makes.
Common questions
How much does spray foam insulation cost in Calgary?
It depends on the area, the thickness, the foam type, access and prep. We measure and give you a written estimate for free, so you get your real price instead of a guess.
Closed cell or open cell: which do I need?
Basements, rim joists, crawl spaces and anything exposed to moisture or deep cold usually get closed cell. Interior walls and sound control can use open cell. We’ll tell you which suits each area when we see it.
How long does the job take?
We give you the schedule with your estimate.
Do I need to leave the house?
You stay out of the sprayed area while the foam cures. We tell you how long before we start.
