Concrete Sealing in Hamilton

Re-seal stamped patios, exposed aggregate driveways, and plain concrete walks across Hamilton. We power-wash, repair, and apply the right sealer for the surface and the season.

Why Hamilton projects need a tailored approach

Hamilton sits on Queenston shale on the Mountain, Iroquois sand and lacustrine clay below the escarpment, and the homes we work on are spread across neighbourhoods like Stoney Creek, Ancaster, Dundas, Westdale, Kirkendall, Stipley, Crown Point, Eastmount, Hamilton Mountain and Waterdown. Mountain lots above the escarpment frequently hit shale within 900 mm, requiring rock-saw work or rebar dowels. Lower city lots in Westdale and Crown Point have variable fill from older infrastructure. Combined with Snow-belt above the escarpment, lake-effect lower city, 20-plus freeze-thaw cycles, escarpment groundwater seeps, this changes how we design the slab and the base.

We pull permits where needed through City of Hamilton Building Services (71 Main Street West), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area L8E through L9C, we serve every City of Hamilton address with the same crew, the same supervisor, and the same written quote.

What a Hamilton sealing job actually involves


Our sealing process

  1. Step 1. Inspection. We walk the slab, photograph cracks and spalls, and check for moisture or efflorescence that needs to be cleared first.
  2. Step 2. Pressure wash. 3000-4000 PSI clean, with degreaser on oily zones and a soft chemistry on coloured stamped surfaces.
  3. Step 3. Repair. Hairline cracks chased and filled, spalls patched with bonded mortar, and joints re-tooled where needed.
  4. Step 4. Dry time. Concrete must read below 4 percent moisture before sealing. In Hamilton that is roughly 24-48 hours of dry weather after the wash.
  5. Step 5. Sealer application. Two thin coats sprayed and back-rolled, with the second coat cross-applied for even coverage.
  6. Step 6. Final inspection. We walk the slab with the homeowner, point out the joint locations, and explain the re-seal interval.
