Calgary paver cleaning and sealing with full joint sand and a salt-shedding sealer
Surface cleaner pass on the pavers, polymeric joint sand replaced where it has washed out, penetrating or film-forming sealer applied once the pavers are fully dry. Locks the colour in, sheds road salt, extends paver life by five-plus years before the next freeze-thaw cycle starts working on the unsealed surface. Most Calgary jobs land between $400 and $1,200 depending on square footage and sealer type.
Sealing without cleaning traps the staining — sealing without sand fails in one freeze-thaw cycle
Calgary paver work falls apart when the steps get skipped. Seal without cleaning first and the algae, leaf tannin and salt staining gets locked under the sealer for years. Seal without replacing the polymeric joint sand and the first spring snowmelt washes the sealer down between the pavers along with whatever sand is left, leaving an uneven finish. The right sequence is clean, dry, sand, seal — each step depends on the one before.
The sealer choice matters too. Penetrating sealer (silane or siloxane) soaks into the paver body, repels water and salt without changing the surface texture. Film-forming sealer (acrylic) sits on top and adds gloss or a wet-look finish, looks great on a covered patio, dangerous on a winter walkway. For most Calgary driveway and walkway projects we use penetrating, film-forming stays on covered back patios. Pair with concrete cleaning when the property has mixed surfaces or with sealing services for the full sealing menu.
Recent work
How a Calgary paver job runs
Four visits sometimes, four steps every time
Inspect and surface clean
Walk the project, identify failed joint sand, note any settled or cracked pavers that need replacement first, run the surface cleaner pass to clear staining, algae and the loose grit between the pavers.
Joint sand replacement
Pavers fully dry (24-48 hours after the clean depending on weather), polymeric sand swept into joints to grade, air-blown to settle and clear excess off the paver face, watered down to activate the polymer bond.
Drying period
Sand cures for another 24-48 hours before sealer goes on. We confirm the joints are bonded and dry before booking the sealer visit. Rain shifts the schedule, we will tell you the new window.
Sealer application and cure
Penetrating or film-forming sealer applied at the right ambient temperature (above 10°C, no rain forecast for 24 hours). Walkaround with you once the sealer cures. Invoice covers all visits in the project.
Calgary paver realities
Road salt, freeze-thaw and the polymeric sand five-year clock
Calgary pavers face two specific problems most cities do not. Road salt that comes off the boots and the tires soaks into unsealed paver bodies and starts the freeze-thaw spalling cycle — the surface flakes off in five to seven years, half the lifespan of properly sealed pavers. Polymeric sand that was installed by the original hardscaper rarely makes it past year seven because the chinook expansion and contraction cycles break down the polymer binder. By year ten on most Calgary driveways and walkways, the sand is washing out and the pavers are starting to shift.
The annual or biennial paver service catches all of this. Clean, replace sand where it has gone, re-seal every three to five years. Pair the paver work with driveway cleaning when the front driveway is concrete and the walkway is pavers, with patio cleaning when the back patio is mixed flatwork, or with pool deck cleaning when the pavers wrap around a pool. Talk to us about a multi-year maintenance plan if the property has a lot of paver surface.

Flatwork and sealing services on the same visit
Paver work often pairs with concrete and sealing across the property. When the surface cleaner and sealer are already on the truck, the per-square-foot price drops on the bundled scope.
Five questions that come up on most paver cleaning and sealing quotes.
Paver cleaning is the surface restore — surface cleaner pass plus targeted chemistry on the stains. Paver sealing adds two more steps: replace the joint sand (the polymeric sand between the pavers that washes out with rain and snowmelt) and apply a penetrating or film-forming sealer that locks the colour and sheds road salt. Sealing without cleaning first traps the staining underneath, so the two services are bundled.
Polymeric sand has a five-to-seven-year life in Calgary's freeze-thaw climate, sometimes less if it was installed in cold or wet conditions. The polymer binder breaks down under repeated chinook expansion and contraction, the sand loses its grip on the paver edges and washes out with the spring snowmelt. Replacement sand goes in dry, gets watered down to activate the polymer, then dries to a solid bond again.
Film-forming sealers (the gloss or wet-look finish) do increase slip risk in winter — film on the paver plus a thin layer of ice equals trouble. Penetrating sealers (the natural-look finish that soaks in) do not, the paver surface stays as textured as it was before. We default to penetrating for driveways and walkways in Calgary, film-forming only for back patios under cover where ice is not a factor.
Penetrating sealers last three to five years on Calgary driveways and walkways, longer on patios under cover. Film-forming sealers last two to three years on patios, less on flatwork that gets foot traffic. Both extend the paver life by five-plus years compared to unsealed because the road salt cannot soak into the paver body and start the freeze-thaw spalling cycle.
Yes, but as a separate priced add-on. We carry common interlock styles (Roman, Holland, paver tile) in basic colours so individual unit replacement is straightforward, but we are not a paver installer. If a section has settled because the base failed, the right fix is a paver re-lay from a hardscaping contractor. We will name one from our trades list if needed.

Interlock walkway around the pool. Polymeric sand had been washing out for three years. Hartford did the clean, sand replacement, then the penetrating sealer two days later. The walkway looks like the install date and the sand finally stays put.

Paver driveway plus a back patio at the same visit. They explained penetrating vs film-forming for each and recommended different sealers for the two surfaces. The driveway stays slip-safe in winter, the patio has that wet-look pop in summer.

10-year-old paver driveway had four cracked units and one sunken section. The crew told me upfront the settlement needed a hardscaper, not them, and named a contractor. Replaced the cracked ones from stock, sealed the rest. Honest call.

Back patio with a fire pit. Pavers had years of soot staining around the pit. They pre-treated, ran the surface cleaner, sand and sealed in three visits over a week. Worth the schedule for the result.
