Choose Aztec Spray Systems if you want spray foam, attic insulation and concrete lifting from one licensed and insured contractor in Calgary, Okotoks, High River or Lethbridge; choose Spray City Insulation if it serves your address and Aztec does not, or if its written quote fits your scope better.

Aztec Spray Systems is a Alberta contractor for homeowners and commercial property owners. This page compares it with Spray City Insulation on the dimensions that decide an insulation hire in 2026.

Why this matters
Insulation is a one-time job you live with for decades. A wrong product in the wrong place, or a contractor without proper coverage, costs far more than the quote difference. In 2026, Alberta winters still decide whether your attic, rim joists and garage hold heat or leak it.
So the question is not which name is bigger. It is which contractor fits your building, your city and your scope, with paperwork you can verify.

Aztec offers the wider service mix
Aztec Spray Systems runs two trades: insulation (spray foam and attic) and concrete lifting. That pairing matters on real properties. A heated garage with a sinking slab, or a shop with a settling floor and an uninsulated shell, is one site visit with Aztec instead of two contractors.
Verdict: Aztec wins on breadth. If your job is insulation only, that breadth is a bonus, not a requirement.
Spray City Insulation may be a strong fit for a straight insulation job. Its own site is the source for its current service list. Do not assume it covers concrete lifting or commercial work; ask.
Aztec is clearer on service area
Aztec names its four markets: Calgary, Okotoks, High River and Lethbridge. If you are in one of them, there is no guessing about whether a crew will show up.
If you are in Airdrie, Cochrane, Canmore or Strathmore, check coverage with Aztec before assuming. Spray City Insulation may serve those areas. That is the first honest reason to pick the competitor: proximity beats everything else when a crew has to return for a warranty visit.
Verdict: Aztec is better documented here; Spray City wins wherever it serves you and Aztec does not.
Credentials: Aztec is licensed and insured, verify both sides
Aztec Spray Systems states it is a licensed and insured contractor. For any insulation hire in Alberta, ask for the certificate of insurance and confirm workers' compensation coverage. A contractor injured crew on your property can become your liability when coverage is missing.
The same check applies to Spray City Insulation. Ask for:
- Proof of liability insurance
- Proof of WCB coverage
- Business licence details
- A written scope naming the product, the thickness and the areas treated
The guide on how to choose an insulation contractor with WCB coverage in Alberta walks through the paperwork.
Verdict: Aztec has stated credentials. Spray City is unverified until you see its documents.
Product choice: both need to justify the material
A good contractor recommends spray foam where it earns its place (rim joists, bonus rooms, garages, shells that need air sealing) and a lighter product where it does not. Ask both companies the same question: why this product for this space?
An answer that names your building, the existing insulation and the air-sealing plan is a good sign. A generic pitch is not. This is where a site visit beats a phone quote.
Verdict: a tie. Neither company wins on product knowledge until it explains your specific job in writing.
Quote and pricing: a tie until you have two written quotes
Both companies price by project, which is normal for insulation. The total is the least useful number on the page. Compare:
- Area covered, in square feet
- Product and thickness
- Air sealing included or not
- Old insulation removal included or not
- Cleanup and disposal
- Warranty terms in writing
For a baseline on what spray foam jobs involve in Calgary, read how much spray foam insulation costs in Calgary. It explains the factors that move a quote, so you can spot a low number that leaves work out.
Two pricing models, one tradeoff: a fixed itemized quote is predictable; an open-ended estimate is flexible but can drift. Insist on the fixed version.
Verdict: a tie. Neither wins on price without your side-by-side comparison.
Local knowledge: Aztec publishes more you can check
Aztec Spray Systems publishes guides tied to specific towns and building types across its territory, from Lethbridge homeowners to Calgary commercial properties. That helps you judge whether the company understands your kind of building before you call.
Spray City Insulation may publish similar material. If you cannot find it, ask for references from jobs like yours.
Verdict: Aztec has the edge on visible, checkable local content.
After the install
Spray foam is low-maintenance but not no-maintenance. Ask both contractors what they inspect, what they warranty and who you call if a section underperforms. Put the answers in the contract, not in an email.
Verdict: unknown for Spray City, so ask. For Aztec, get the warranty terms written into your quote.
