Hardscaping in Ottawa is priced per square foot, and the per-foot number is the first thing everyone asks for. Here are the published figures for each kind of work, what that number covers and what it leaves out, and how to turn them into a budget for a whole yard.
These are third-party figures, not our quotes. They are the ballpark most Ottawa homeowners start from.
| Work | Published installed price | Source |
|---|---|---|
| Interlock patio or walkway | $18 – $45 / sq ft (most quality work mid-to-high $30s) | Allen Landscaping |
| Interlock driveway | Patio rates plus about $2 / sq ft for 80 mm pavers, and a deeper base | Maverick Landscaping |
| Poured concrete | $15 – $25 / sq ft | Allen Landscaping |
| Stamped concrete | $22 – $35 / sq ft | Allen Landscaping |
| Concrete-block retaining wall | $35 – $65 / sq ft of wall face | RenoQuotes |
| Natural stone retaining wall | $60 – $110 / sq ft of wall face | RenoQuotes |
Patios: the core of most budgets
Allen Landscaping splits installed interlock into three tiers: economy at $18 to $22 a square foot, mid-range at $25 to $35, and premium at $45 and up. It recommends budgeting $30 to $40 a square foot for a mid-range professional install.
Applied to a typical backyard patio:
- 250 sq ft at $30–$40: about $7,500 – $10,000
- 400 sq ft at $30–$40: about $12,000 – $16,000
- 600 sq ft at $30–$40: about $18,000 – $24,000
All before HST. Bigger and simpler comes in lower per foot, because setup and finishing time spread over more square feet. Small and detailed comes in higher. Material is the main lever within the band. Standard concrete pavers sit at the bottom, and large-format slabs and natural stone at the top. Allen puts locally made concrete pavers at $5 to $9 a square foot for material alone, and imported or natural stone at up to $20 before installation.
Our interlocking patio cost guide goes deeper on the four things that move a patio price, and patio construction in Ottawa covers materials, permits and the timeline.
Walkways and steps
Walkways are priced like patios, per square foot. Steps are priced as their own item, per step or per flight, because each one is built and levelled individually and often sits on its own footing.
A narrow walk costs more per foot than a patio. It has more edge per square foot, more cuts and more edge restraint, and it often runs along the house where the grade has to slope away from the foundation. Front steps also have to meet the Ontario Building Code’s rise, run and handrail rules. Our guide to stone walkways and front steps covers those rules and how a walk is built so it does not heave.
Driveways
A driveway costs more per square foot than a patio for two structural reasons. Driveway pavers are 80 mm thick instead of the 50 mm used for patios, which adds about $2 a square foot in material. And the base has to carry vehicles and a plow through freeze-thaw, so it is dug deeper and compacted in more lifts. Allen notes driveways need 18 inches or more of excavation, against 10 to 14 for a patio.
Driveways are also big. Even a modest double driveway is often larger than most patios, so the total climbs quickly. A permeable system costs 10% to 20% more than a standard one, according to Maverick, and is worth pricing where drainage is a problem. Our interlock driveway cost guide has the full breakdown, including the City’s rules on widening.
Retaining walls
Walls are priced per square foot of wall face, height times length, not per square foot of yard. RenoQuotes gives a typical $35 to $90 a square foot for a standard 3 to 4 ft residential wall, or about $150 to $400 a linear foot, with concrete block at $35 to $65 and natural quarry stone at $60 to $110. Its worked example is a 3 ft by 30 ft block wall, 90 sq ft of face, at $3,150 to $5,850.
What moves a wall price is mostly below grade: the excavation, the compacted base and buried first course, the drainage stone and pipe behind the wall, and the geogrid that ties a taller wall back into the slope. RenoQuotes estimates that excavation, soil preparation and drainage make up about 30% of a typical wall budget. Taller walls, walls with a driveway or pool above them, and tiered walls may need an engineer. RenoQuotes puts sealed engineered plans at $1,500 to $3,500.
Our guide to what makes a retaining wall last in Ottawa explains when a wall needs engineering, and retaining walls in Stittsville covers the larger, sloped lots out there.
Pool surrounds and outdoor living
Pool decks are priced like patios, plus coping around the pool edge, which is priced per linear foot and cut piece by piece. Larger pool and multi-level projects take two to four weeks rather than days. Fire-pit pads, outdoor-kitchen platforms and pergola footings are each priced as items on top of the surface around them. Our pool deck design guide and outdoor living in Stittsville cover those pieces.
What the per-foot price leaves out
The per-square-foot figure covers the surface. A real quote adds lines that are easy to miss when you compare. Allen lists several:
- Removal and disposal. Tearing out an old patio, deck or concrete pad. Landfill tipping fees run about $160 to $170 a tonne, and Allen estimates a 500 sq ft patio can produce around 30 tonnes of waste, or $4,000 to $5,000 to dispose of.
- Access. A yard that a mini-excavator cannot reach means digging and moving base by hand or with smaller machines, which raises labour.
- Locates. Ontario One Call locates for public utilities are free. Private lines such as pool, lighting or gas lines to a barbecue need a private locator, which Allen puts at $200 to $500.
- Restoration. Repairing the lawn, fences and anything else the equipment crossed, at $1,000 to $2,500.
- Sealing. Optional, at $2 to $5 a square foot, applied 60 to 90 days after installation.
- Steps, walls, lighting and edging details, each priced as its own item.
Why the base is most of the price
Allen estimates the stone itself is only 20% to 30% of the total bill. Most of the rest is the work below the surface, and on Ottawa’s clay that work decides whether a patio is still flat in ten years.
We install a minimum of 8 inches of compacted Granular A under pedestrian patios and 10 to 12 inches under driveways, with geotextile fabric below and an edge restraint at the sides. That is deeper than the ICPI’s minimum for well-drained soil, because most Ottawa lots are not well-drained. Our guide to patio base depth and Ottawa freeze-thaw explains why.
When one quote is much lower than the others, the base is usually where the difference is. Ask every contractor to write the excavation depth and base depth in inches.
Budgeting a whole yard
Most hardscape projects are more than one item. A realistic backyard budget is the sum of the pieces, not one per-foot rate:
- The main surface, in square feet times your tier.
- Steps and walls, priced separately.
- Removal of what is there now.
- Features: a fire pit pad, lighting, an outdoor-kitchen platform.
- Softscape around the edges: sod repair, beds and planting. Our guide to hardscape versus softscape covers how a budget divides between them.
- 13% HST on the total.
If the budget does not stretch to everything, build the structural pieces now (the grade, the walls, the main surface) and add features later. A fire pit or lighting can go in next year. A patio built on a shortcut base cannot be fixed without lifting it.
Quotes, licences and your protections
Since March 1, 2026 the City of Ottawa has required hardscaping contractors to hold a municipal Hardscaping Contractor licence. Ask to see it.
Ontario’s consumer guidance on renovations recommends at least three written estimates and a deposit of no more than 10%. The final price cannot exceed the estimate by more than 10% unless you agree to new work or a new price. Our guide to hiring a hardscaping contractor in Ottawa covers what a proper quote must spell out.
Timing helps too. Allen notes that booking in the off-season can save 5% to 10%, and a winter booking gets you a spring start rather than a slot in August.
Getting a real number for your yard
No per-foot figure replaces a site visit. We quote hardscaping at a fixed price after measuring the yard and digging a test hole, with the excavation depth, the base, the material line, the drainage and every extra written out. That way you can compare our quote line by line with anyone else’s.
The full scope is on our hardscaping page. We build across Stittsville, Kanata, Nepean and Barrhaven, and our local guides cover hardscaping in Stittsville, Kanata and Nepean.
Book a free on-site estimate. We will measure the yard, check what is under it, and send a written, fixed-price scope for your project.
