The homeowner’s guide

Why interlock fails (it's never the stone)

Pavers don't wear out; bases do. Under every wavy, sunken GTA driveway is a base that was too shallow, poorly compacted, or built on unprepared clay. Do it right and you excavate 8–12 inches, lay geotextile so the granular doesn't sink into the clay, then compact granular in 4-inch lifts before a paver ever shows up. That's most of the labour and most of the cost, and it's buried where you can't see it. Which is exactly why cheap quotes skip it.

Frost heave, the Toronto special

Water gets under pavers, freezes, expands about 9%, and lifts whatever sits above it. Come thaw, things settle unevenly. Repeat forty times a winter. A proper base drains so there's less water to freeze, and polymeric sand in the joints hardens to keep new water from getting in. That's why re-sanding joints every 2–3 years is the one maintenance job interlock actually asks of you.

Natural stone vs interlock, honestly

Flagstone looks incredible and no two patios are alike, but it costs more, and dry-laid flagstone wants a fussier base and periodic re-levelling. Concrete pavers are engineered to be uniform, stronger than poured concrete per square foot, and any single damaged unit lifts out and swaps. Driveways: pavers, almost always. Garden paths and showpiece patios: stone earns its price. We install both and we'll tell you where each belongs.

Lift-and-relevel: the repair nobody tells you about

If your interlock is wavy but the pavers themselves are sound, you don't need a new patio. We lift the affected field, rebuild and compact the base under it, and relay the same stones with fresh joint sand. It runs a fraction of full replacement, usually $2,000–$6,000, and the result is dead flat. Contractors who only sell full teardowns don't love this option. It's still the right call for a lot of homes.

Your once-a-season walk-around

No paver rocks or clicks when you step on it Joints are full of sand, not weeds or ants Border/edge stones stand vertical, not leaning outward No pooling on the surface an hour after rain Steps and edges are still level with each other No white haze (efflorescence) spreading from the joints Downspouts don't discharge directly onto the pavers

Tick what checks out. Anything you can’t tick is worth a closer look.

Things people get toldthat aren’t quite true

“Weeds grow up from under pavers”

They grow down, from seeds landing in joints with old, tired sand. The fix is joint maintenance, not nuking the patio. Fresh polymeric sand starves them out.

“Sealing is mandatory”

Sealing deepens colour and makes stains easier to lift. It doesn't hold a patio together. Skip it entirely if you like the natural look; the base doesn't care.

“Poured concrete lasts longer than pavers”

Poured slabs crack, and the crack is forever. Pavers move as units and can be relaid. In freeze-thaw country, a repairable surface beats a monolithic one over 20 years.
