Pool Deck Sealing in St. Thomas
Pool season in St. Thomas means months of wet feet, splash-out and direct sun on the surrounding deck, and All-Seal's pool deck sealing in St. Thomas is built around exactly that. Anti-slip additive comes standard on every pool deck we seal in St. Thomas, protecting against chlorine staining, algae growth and the freeze-thaw damage that follows once the pool closes for winter. Book a free inspection ahead of pool season in St. Thomas to get your deck ready before the first swim of the year.
Recommended finish
Matte
Matte is standard around pools because it pairs naturally with the anti-slip additive and avoids the glare a glossier finish can create in direct sun near the water.
St. Thomas's elevation and proximity to the Lake Erie shoreline mean concrete here experiences more humid, muggy stretches in July and August than towns further inland, which affects how long a sealer takes to cure properly before rain.
What's included
Pool Deck Sealing done properly in St. Thomas
A pool deck lives in water and sun for months at a time, which makes it one of the hardest surfaces on your property to protect. All-Seal seals pool decks with anti-slip sealers that guard against chlorine, water damage and algae while keeping bare feet safe.
- 1
On-site inspection
We assess the full pool surround, checking drainage, existing cracks and how the deck currently handles splash and rain water.
- 2
Pressure washing
The deck is pressure washed to remove algae, mildew, sunscreen residue and chlorine deposits before anything is sealed over top.
- 3
Crack and joint repair
Cracks near coping, steps and drains are repaired first, since these are the areas most exposed to standing water around a pool.
- 4
Full drying period
We make sure the deck is completely dry before sealing, which matters even more around a pool where humidity lingers longer.
- 5
Anti-slip sealer application
Sealer with anti-slip additive is applied evenly across the full deck for a consistent, safe texture underfoot.
- 6
Coverage and safety check
We check the finished deck for even coverage and confirm the anti-slip texture feels right before considering the job complete.

FAQ
Pool Deck Sealing in St. Thomas

Call 519-266-6796What does pool deck sealing cost in St. Thomas?
Every quote is per property, based on square footage, the type of concrete and whether it was sealed before. The inspection in St. Thomas is free and the written quote includes the recommended sheen.
Is anti-slip additive included automatically?
Yes. Anti-slip additive is standard on every pool deck we seal, since safety around wet, bare feet matters more here than on almost any other surface.
Will sealing make the deck cooler in summer?
A properly sealed, even-toned deck tends to stay more comfortable underfoot in direct sun compared to a weathered, unsealed surface, though exact temperature depends on sun exposure and concrete colour.
Can sealing stop algae from growing on my pool deck?
Sealing significantly reduces how much moisture the concrete holds in shaded, damp areas, which limits the conditions algae need to take hold, though regular cleaning is still recommended in low-sun spots.
Do you charge extra to come to St. Thomas?
No. St. Thomas is inside our regular service area and inspections there are free.
