Driveway Sealing in St. Thomas
Homeowners in St. Thomas deal with the same combination of road salt, freeze-thaw cycles and clay-heavy subsoil that makes driveway sealing worthwhile anywhere in Southwestern Ontario. All-Seal's driveway sealing in St. Thomas starts with a free on-site inspection so we can see exactly how your slab is holding up before recommending a plan. Whether your driveway in St. Thomas is a few years old or has an existing sealer that needs attention, we will walk you through the right approach and a straightforward quote.
Recommended finish
Semi-Gloss
Semi-Gloss gives a driveway a clean, satin finish that resists salt and UV fading without an overly glossy look across such a large surface.
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
Driveway Sealing done properly in St. Thomas
Your driveway takes the brunt of every freeze-thaw cycle, every bag of road salt, and every oil drip from the car. All-Seal applies premium sealers built to stop that damage before it starts, so your driveway keeps its strength and its curb appeal.
- 1
On-site inspection
We walk the full driveway, check existing cracks and joints, and note any prior sealer so we can plan the right approach before we quote.
- 2
Pressure washing
The entire surface is pressure washed to lift ground-in salt residue, oil film, tire rubber and loose debris that would otherwise trap moisture under the new sealer.
- 3
Crack and joint repair
Cracks and control joints are cleaned out and filled so water cannot keep working its way underneath the slab through the winter.
- 4
Full drying period
We let the surface dry completely before applying anything. Sealer applied over damp concrete traps moisture instead of keeping it out.
- 5
Sealer application
Your chosen sealer is applied in even, controlled coats across the full driveway, edges and apron included, so there are no thin spots or lap marks.
- 6
Sheen and finish check
We walk the finished surface with you to confirm even coverage and the sheen level you selected before we consider the job complete.

FAQ
Driveway Sealing in St. Thomas

Call 519-266-6796What does driveway 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.
How often does a driveway need to be resealed?
Most driveways hold their protection for 2 to 5 years, depending on traffic volume, how much sun exposure the surface gets and how much road salt is tracked onto it each winter. We will give you a realistic estimate for your driveway during the inspection.
Can you seal a driveway that already has cracks?
Yes. Cracks and joints are cleaned out and repaired as part of the process before sealing, so the new coating goes over a stable, filled surface rather than sitting over an open crack.
Will sealing change the colour of my driveway?
A quality sealer typically deepens and enriches the existing concrete colour slightly rather than changing it. If your driveway is plain grey concrete, it will still look grey, just with a cleaner, more uniform finish.
Do you charge extra to come to St. Thomas?
No. St. Thomas is inside our regular service area and inspections there are free.
