Concrete Sealing Calgary
We seal patios, pool decks, sidewalks, exposed aggregate, and stamped concrete across Calgary. Right sealer, right prep, done properly.
Concrete sealing in Calgary typically costs $150–$700 for residential surfaces. Most jobs take half a day. Calgary's freeze-thaw cycles and de-icing salt degrade unsealed concrete within 5–8 years — sealing every 2–3 years is the cheapest way to protect what you already have.

Concrete Surfaces We Seal in Calgary
Patios
Exposed aggregate and stamped concrete patios take a beating from Calgary's UV and freeze-thaw cycles. Sealing every 2–3 years maintains colour and prevents surface failure.
$200–$600
Pool Decks
Non-slip, UV-stable sealers for wet environments. Water intrusion + freeze-thaw on an unsealed pool deck causes serious cracking fast.
$250–$700
Sidewalks & Walkways
Concrete walks sit right in the salt spray zone. Penetrating sealer blocks salt penetration and prevents the surface scaling that makes walks crumble within 5–8 years.
$150–$400
Exposed Aggregate
Silane-siloxane penetrating sealer locks aggregate in place and protects against weathering. Can be topped with a wet-look acrylic if colour enhancement is desired.
$200–$500
Stamped Concrete
Film-forming acrylic or polyurethane protects colour and pattern detail. Can refresh significantly faded stamped concrete — gloss or satin finish.
$250–$600
Garage Aprons & Steps
The most salt-exposed concrete on your property. Often overlooked. Sealing the apron protects the transition between driveway and garage.
$100–$300
Is Concrete Sealing Worth It in Calgary?
Short answer: yes — by a wide margin.
The math on sealing vs. replacement:
- Sealing every 2–3 years: $200–$600
- Replacing a concrete patio: $5,000–$15,000+
- Properly sealed concrete lasts 30–50 years vs. 10–15 unsealed in Calgary's climate
Sealing makes the most sense for:
- →Decorative stamped or coloured concrete (colour fades fast without it)
- →Exposed aggregate (aggregate loosens within a few years unsealed)
- →Pool decks and surfaces that see constant moisture
- →Any concrete in direct contact with de-icing salt or meltwater
Penetrating vs. Film-Forming Sealers — Which Is Right for Your Surface?
Penetrating Sealers (Silane-Siloxane)
Chemically bond below the surface. Don't change appearance much. Best for: natural-look concrete, high-traffic areas, surfaces where slip resistance matters.
Lasts: 5–8 years
Film-Forming Sealers (Acrylic / Polyurethane)
Sit on top of the concrete. Enhance colour, add sheen. Best for: stamped concrete, coloured concrete, exposed aggregate where you want a wet look.
Lasts: 2–3 years before reapplication
What Can Go Wrong With Concrete Sealing
Most sealer failures are preventable with proper prep and product selection.
Applying sealer over failing old sealer
New sealer over peeling old sealer just fails at the same rate. We assess existing sealer condition and strip it if needed before reapplying.
Wrong sealer for the surface
Film-forming sealers on high-traffic areas can peel. Penetrating sealers on decorative surfaces won't enhance colour like the homeowner expects. The product choice matters.
Sealing in cold or wet conditions
Sealer applied below 10°C or with rain in the 24-hour forecast fails adhesion. We check conditions before every job.
Ignoring active damage first
Sealing over cracks or spalling doesn't fix the underlying issue. Surface prep and crack repair happen before any sealer goes down.
