Patios near you

No single surface wins in every yard: each one looks, feels underfoot, handles frost and ages differently.

Every hard patio rests on the same idea: dig out the topsoil and anything soft or organic, then build a bed of crushed stone compacted in layers so it stays firm and lets water through. Pavers, flagstone and slabs sit on a thin levelling layer over that base, while concrete is poured directly on it. The right depth depends on the soil, how wet the site stays and what the patio will carry. Because the base is buried within a day or two, ask to see it before the surface goes down, or ask the crew for photos.

The finished surface needs a gentle fall away from the foundation, toward lawn, a garden bed, a swale or a drain, so rain and meltwater never pool against the wall or spill into a window well. A patio that meets the house should sit far enough below the door sill that water and drifting snow stay outside. Redirect any downspout that would empty onto the patio before construction starts, or it will lay down a sheet of ice every winter. If the lot already drains toward the house, the grading gets corrected first.

Frost is the main reason patios fail in Canadian yards. Wet, fine-grained soils such as clay and silt swell as the water in them freezes, pushing up whatever sits above, then settle unevenly as they thaw. A rigid slab can crack when that happens, while pavers and stones rise and fall one by one and end up out of line. The defence is mostly about water: a free-draining base, a surface that sheds rain, and no low spot or downspout feeding water underneath.

A patio feels right when it's sized for what actually happens on it. Place the table with the chairs pushed back, the barbecue with clearance from siding and railings, and the lounge chairs where the evening sun reaches them, then outline the area with stakes and string and try the furniture in place. Consider the route from the kitchen door, the direction of the wind, and whether neighbouring windows look straight down on the space.

A patio laid at ground level rarely needs a building permit, but that's a municipal decision and the details matter. Toronto's permit guidance, for example, requires a permit for a deck more than 60 cm above the ground, while an uncovered platform below that height that isn't part of a required exit needs none, provided it complies with zoning. The same guidance requires a permit to enclose an existing deck, porch or patio of any size, so adding walls, a roof or screens can change the answer.

Zoning applies even when no permit does. Municipalities commonly limit how much of a lot, and especially a front yard, may be hard-surfaced, set distances from lot lines and expect runoff to stay on your property. Where bylaws are set by boroughs, as in Montreal, ask the borough's permit office before the design is final.
