Interlock paving is one of the most popular exterior upgrades in Montreal — and one of the most misquoted. Prices online range wildly, and most guides are written for warmer climates that don't deal with our freeze-thaw cycles. Here's what you should actually expect to pay in 2026, and why the cheapest quote is almost never the right choice in Quebec.
Average interlock paving costs in Montreal (2026)
- Basic concrete pavers, standard pattern: $18–$25/sq ft installed
- Premium natural stone or clay brick: $28–$45/sq ft installed
- Driveway (standard two-car, ~50 sq m): $12,000–$22,000
- Patio or backyard terrace (~30 sq m): $7,000–$15,000
- Walkway or path (~10 sq m): $2,500–$5,000
What drives the price
The biggest variable is the base. In Montreal, a proper interlock installation requires removing the existing surface, excavating 40–50 cm, laying a compacted gravel base, then a sand setting bed, then the pavers. Skip any of those steps and your pavers will shift and heave after the first winter. Contractors who quote significantly lower are almost always cutting corners on the base.
Other cost factors
- Paver type and thickness (residential vs. commercial grade)
- Pattern complexity — herringbone and fan patterns cost more labour
- Slope and drainage requirements
- Demolition and removal of existing driveway or patio
- Edging, borders, and stairs
Will interlock add value to my property?
Yes, consistently. A well-installed paver driveway typically returns 70–80% of its cost in property value in the Montreal market, and it dramatically improves curb appeal. When you factor in that asphalt requires re-sealing every 2–3 years and repaving every 15–20 years, quality interlock that lasts 30+ years often costs less over time.
