We’re Interlock Experts, a family-owned Ottawa interlock installation company that was established in 2009. For over 17 years, we’ve been providing outstanding service to Ottawa homeowners. By the time we’re done working together, you’ll feel like family.
Ottawa's frost line is 4 feet deep. A 4-inch base lifts the second winter. A 10-12 inch base stays put for 25+ years. That is the only reason our driveways still look straight a decade later.
Same family-owned crew runs every project from first site visit to final walkthrough. Headcount stays at 11 on purpose so the lead installer is on-site at least 80% of every install.
Our crew installs every paver, every joint, every base course. We hold the standard because we hold the equipment. Subcontracting interlock is how most jobs go wrong.
514 of our last 528 projects had the written quote in your inbox under 24 hours of the site visit. The other 14 took 48. Same-day reply on phone and email every business day.
Takes 30 seconds. Then a 20-minute visit, no obligation.
Itemized. No surprises. No pressure, no follow-up calls.
Permits, demolition, drainage and cleanup. We work around your schedule.
Plywood paths, drop cloths, careful crew. Full sweep, every day.
Every Ottawa interlock driveway we build starts on a 10-12 inch frost-proof base, so it stays dead straight through decades of freeze-thaw. The tiers below are real Ottawa numbers – your exact figure comes after a free on-site measure.
