How Much Does Interlock Cost in Ontario? Walkways, Patios & Driveways
If you are pricing out interlock for the first time, the numbers online are all over the place. Some sites quote a flat price per square foot. Others won't give a number at all. The truth is somewhere in between: interlock pricing follows a few predictable factors, and once you understand them you can budget with confidence before you call anyone.
Below is how we price interlock projects at Klutch Landscaping, with real numbers from the jobs we build across Innisfil, Barrie, Bradford, Newmarket and the surrounding area.
A real starting point: the front walkway
A typical front walkway, around 20 feet long by 5 feet wide, costs about $4,500 plus tax on average. That covers excavation, a compacted granular base, bedding, the pavers, edge restraint and polymeric sand.
That's a useful benchmark because it's the most common small project we build. Bigger or more detailed work scales up from there.
What drives the price up or down
1. Size and shape
Square feet matter, but so do curves, steps and borders. A straight rectangular walkway is faster to cut and lay than one with sweeping curves, a contrasting soldier course border and a landing. More cuts means more labour.
2. Excavation depth and base
This is the part you never see and the part that matters most. For a walkway or patio, we excavate 10 to 12 inches deep depending on soil. For driveways and driveway extensions, we go 16 to 18 inches deep, because they carry vehicle weight. Deeper excavation means more digging, more material hauled away and more gravel brought in, so a driveway costs more per square foot than a patio of the same size.
Skipping base depth is the most common way cheap interlock ends up sinking. We cover that in detail in our post on why interlock sinks.
3. Paver choice
Standard concrete pavers sit at the lower end. Large-format slabs, textured or natural-look finishes, and premium product lines cost more per square foot and are often slower to install because they are heavier and less forgiving.
4. Access
If a machine can't get to the work area, everything gets moved by hand or by smaller equipment. For backyard projects we need a minimum of 48 inches of access at the narrowest point to work efficiently. Tight side yards, fences and decks in the way all add time.
5. Steps, walls and extras
Natural stone steps, armour stone, lighting, seat walls and drainage work are priced separately and can be a big part of the total. A walkway with a stone step at the front door costs noticeably more than a flat walkway.
Patios vs walkways vs driveways
Walkways: smallest footprint, usually the best entry point. The $4,500 benchmark above is a good guide for a standard front walk.
Patios: larger and often paired with steps, walls or a fire feature. If you're planning any backyard project, a realistic minimum budget is $25,000 plus tax.
Driveways and extensions: the deepest excavation and the heaviest base. Driveway widening is one of our most common requests, and it usually needs a permit. We handle that paperwork.
Hidden costs to ask about
When you compare quotes, check whether these are included:
Utility locates (required by law, and we arrange them through Ontario One Call)
Removal and disposal of old concrete or asphalt
Edge restraint and polymeric sand
Grading and topsoil around the finished area
Permits where needed
Warranty length
At Klutch, all hardscape work comes with a three-year workmanship warranty.
How to get an accurate number
The fastest way to an accurate price is a site visit. We measure, check soil and access, talk through materials and give you a written quote. For larger projects, a design plan helps lock in the scope so the price doesn't drift once work starts.
