Interlock in Selkirk.

Selkirk is approximately 25 min from the Hagersville base. Travel for interlock depends on scope and scheduling. Interlock fails when the base does. Most contractors skimp on the granular — we don't. Pavers also need re-laying every 15–20 years; we do that too.

FAQ

Interlock in Selkirk — common questions

  • Yes. Lake-effect snow and clay soil. Snow contracts are a big part of our Selkirk work — we know which laneways drift. Driveways, walks, patios — plus re-laying stones that have settled.

  • Interlock jobs typically start at $22/sq ft. Final price depends on access, prep, size, and finish. We quote a fixed price after seeing the site — no hourly creep.

  • About 25 min (22 km). It's a normal part of our week.

  • Two reasons: regular sand was used instead of polymeric, or the polymeric has aged out (5–10 years). Solution: blow joints clean, re-poly, water in, done.

  • Base failure. Either it was undersized, or water got under it and froze. Re-lay = lift the stones, re-base properly, re-set. Most stones are reusable.

  • Interlock costs more upfront but lets you fix one stone if you stain it. Concrete is faster and cheaper but cracks travel. Both last decades installed correctly.
