Interlock Driveway in Canada: what's involved, what it costs, and how to hire
CentFix
Updated regularly · Canada-wide
Before booking interlock driveway, it helps to know what the visit actually involves, what can change the price on the day, and which questions separate a company that has thought it through from one guessing on the phone.
CentFix is a matching service. You describe the job once and we connect you with independent landscaping contractors who serve your address. Licensing, insurance, warranties and reviews belong to the individual businesses that earned them.
Everything below is written for interlock driveway specifically: scope, what pushes a price up or down, realistic timelines, the rules that apply in Canada, and the questions worth asking before anyone starts.
What interlock driveway involves
Interlock Driveway sits within landscaping work, so the same fundamentals apply: proper assessment first, then the work itself, then a check that the result holds up. A landscaper who quotes without looking is quoting the job they hope it is.
Hardscape is the built portion: patios, walkways, retaining walls, steps, driveways and edging. The visible material is a small part of the work. Excavation depth, base material, compaction and drainage decide whether it stays flat after five winters.
Softscape is the planted portion: lawns, garden beds, trees, shrubs, soil improvement and mulch. Success here depends on matching plants to hardiness zone, sun exposure and soil, and on preparing the soil rather than dropping plants into whatever is already there.
- Patios, walkways and interlocking stone installation
- Retaining walls, steps and grade changes
- Grading and drainage corrections, including French drains and swales
- Sod, seeding, lawn renovation and soil improvement
- Garden design, planting, mulching and bed edging
- Seasonal maintenance, cleanups and spring or autumn preparation
What to expect when the landscaper arrives
The first visit for interlock driveway is mostly about scope. Expect questions about how long the issue has been there, what's been done before, and how the space is used, because all three change the recommendation.
- A walkthrough or a few questions before anything is quoted, so the price reflects your property rather than an average
- A clear description of what's included in interlock driveway and what would be treated as extra
- Protection of the surrounding area, and cleanup when the work is finished
- Written pricing, with a note of anything that could change once work is underway
- A plain answer on the warranty: how long it runs and what it actually covers

What affects the price of interlock driveway
Excavation and base work drive hardscape pricing more than the surface material. Deeper base in poor soil, removing existing concrete, and getting spoil off the property all add cost before a single paver is laid.
Access decides how the work happens. A back yard reachable by machine is far cheaper to build in than one where everything is wheelbarrowed through a narrow side gate, sometimes by a factor that surprises homeowners.
Material choice, wall height, plant size and irrigation all add. Retaining walls above a certain height require engineering in most municipalities, which is both a cost and a good idea.
- Square footage and excavation depth required
- Site access for machinery and material delivery
- Base preparation, drainage layers and compaction
- Material selection, from basic concrete pavers to natural stone
- Retaining wall height and whether engineering is required
- Plant sizes, soil amendment and irrigation
How long the work takes and how soon someone can come
A modest patio or walkway typically takes three to five days. Larger hardscape projects with walls and steps run one to three weeks. Planting and lawn work is faster, often one to two days once the beds are prepared.
Season constrains everything. Most landscaping happens between the last frost and freeze-up, and good crews book their season early. If you want work done in June, the conversation usually needs to start in the previous autumn or in late winter.
How to choose the right landscaper for this job
Ask what goes under the surface. A contractor who tells you excavation depth, base material and compaction method has built patios that stayed flat. One who quotes only on square footage of stone has not been asked before.
Look at work they built several years ago rather than last month. Anything looks good the week it is finished. The test in this country is what it looks like after three winters.
- Insurance and workers' compensation coverage
- A written scope stating excavation depth, base material and compaction
- Whether drainage has been considered and how water will move
- Plant warranty terms, if any, and what they require of you
- Photos of projects completed at least three years ago
Questions to ask before you book interlock driveway
You don't need to know the trade to ask good questions. These are the ones that tell you whether a company has actually thought about your job.
- Have you done interlock driveway on a property like mine recently?
- How deep are you excavating, and what base material are you using?
- Where will water go once this surface is in place?
- Does this retaining wall need engineering at that height?
- Are plants selected for my exposure and hardiness zone?
- How will materials reach the back yard, and what happens to the spoil?
- What does your warranty cover on hardscape settling?

Permits, rules and who is allowed to do the work
Retaining walls above a defined height need a permit and often an engineered design in most municipalities. Structures near property lines, and anything altering drainage onto a neighbouring property, can also be regulated.
Utility locates are required before excavation, including for fence posts and deeper planting. It is free and it prevents the very expensive kind of accident.
Municipal rules can also govern tree removal, lot coverage by hard surfaces and how much of a front yard can be paved. Contractors who work locally will know these, but it is worth asking directly.
Seasonal timing and Canadian conditions
Spring is the busiest period and books out fast. Planting is best done in spring or early autumn when temperatures are moderate and roots can establish before extremes.
Autumn is an underrated window. Hardscape crews have more availability, soil is still workable, and work completed before freeze-up settles naturally over winter. Sod also establishes well in cooler weather with less watering.
Common mistakes that cost homeowners money
The recurring landscaping mistake is buying a surface rather than a structure. Money spent on base preparation and drainage is invisible and it is exactly what determines whether the project survives.
- Skimping on excavation and base depth under patios and walkways
- Building surfaces that direct water toward the foundation
- Planting large trees close to the house or the sewer lateral
- Building a retaining wall above the permit threshold without engineering
- Installing sod without preparing the soil underneath
Keeping the work in good shape afterwards
Established landscaping needs seasonal attention rather than constant work. The two things that matter most are keeping water moving away from the building and keeping plants suited to their spot.
- Clear leaves from drains, swales and low points each autumn
- Top up joint sand on interlocking surfaces as it washes out
- Refresh mulch annually to hold moisture and suppress weeds
- Prune shrubs away from siding and foundations
- Watch for settling near the house and correct grading before it becomes a basement problem
Where CentFix fits in
