Hardscaping & Interlocking in Ontario
Hardscaping covers the non-plant, built parts of a property: interlocking paver driveways and walkways, patios, retaining walls, steps, pool decks, and the odd outdoor kitchen or fire pit surround. In Ontario, that work has to hold up through freeze-thaw cycles every winter, which makes base preparation the whole ballgame. A patio that looks identical to a competitor's job on install day can heave, settle, or sink at the joints within two or three seasons if the base wasn't built right. We list 74 businesses doing this work across the province, ranging from small crews that focus on driveways and walkways to larger operations that also handle retaining walls, drainage, and pool surrounds.
What to look for before you sign a contract
Ask about base depth and material for your specific soil and use case (a driveway needs more compacted granular base than a garden path), whether they install polymeric sand and edge restraints, and how they handle drainage and grading away from the house or slope. Get a written scope that specifies square footage, paver product and thickness, base spec, and warranty terms for both labour and settling. Photos of past jobs after a full winter or two tell you more than photos taken the day of completion.
How we score contractors
Our ranking weighs review consistency over time, evidence of proper base work and drainage handling, response to warranty or settling issues, and licensing/insurance where it's disclosed. See the full ranked guide to hardscaping and interlocking contractors for the current list, and read our methodology for how we weigh and verify each factor.

Common questions about hardscaping & interlocking
- How much does interlocking cost in Ontario?
- Most residential interlocking work runs somewhere between $18 and $35 per square foot installed, depending on paver product, base depth required, access to the site, and whether old concrete or asphalt needs to be removed first. Retaining walls and steps cost more per square foot than flat walkways or patios because of the extra labour and materials involved. Get at least two or three quotes with the same scope written out so you're comparing like for like, not just a bottom-line number.
- How often does interlocking need to be redone or maintained?
- A properly installed interlock job with a solid compacted base should last 20 to 30 years structurally, but it needs upkeep along the way: resanding joints every few years, resealing every 3 to 5 years if you want to keep the colour and reduce weed growth, and occasional releveling of a few stones if a spot settles. Poor base prep is the main reason people end up redoing work after only 5 to 10 years.
- What should I expect during the installation process?
- Expect excavation to remove existing material and reach proper depth, then a compacted granular base (often in layers, compacted between each), a bedding layer of sand, the pavers themselves, edge restraints to stop lateral shift, and polymeric sand swept into the joints and set with water. A driveway or larger patio typically takes several days to a couple of weeks depending on size, weather, and crew size.
- How can I judge the quality of a finished hardscaping job?
- Check that the surface has a consistent, gentle slope away from the house or toward a drain (no puddling after rain), joints are tight and even, edge restraints are hidden and not shifting, and cut pieces around curves or borders are clean rather than jagged. Ask what base depth was used and whether they compacted in lifts, since that's the part you can't see once it's finished but it's the part that determines whether the job lasts.
