How Much Does a New Patio Cost? (Paver, Stamped and Poured Concrete)

The number every homeowner wants before anything else gets discussed: a rough range. A new patio in Calgary runs $1,440 to $30,000 depending almost entirely on material and size, and that spread is wider than most cost guides admit. Plain poured concrete sits at the bottom. Natural stone and flagstone sit at the top. Everything else, pavers, stamped concrete, permeable pavers, lands somewhere in between, and the square footage does the rest of the multiplying.

What follows is the breakdown our estimators actually use, sized for the dimensions people search most: 12×12, 20×20, and 24×30. Same per-square-foot bands published on our patio installation page, run through the math so the number matches whatever size is actually on the table.

The Short Answer on Patio Cost

Concrete pavers run $25 to $50 per square foot installed. Natural stone and flagstone climb to $35 to $75. Plain poured concrete sits at $10 to $20, and stamping it for colour and pattern pushes that to $20 to $35. Permeable pavers land at $30 to $55, slightly above standard concrete pavers, since the base runs deeper and the open-joint stone costs more to source. A straightforward 300 square foot residential patio, the size that comes up most on site visits, prices out between $3,000 plain concrete and $22,500 in full natural stone. Site conditions, drainage, and access shift every one of those numbers, and rarely in the direction a homeowner hopes.

Patio Cost Per Square Foot in Calgary, by Material

Material moves the price more than anything else on the quote, ahead of size, ahead of site access. Five options cover almost every patio we build.

Concrete Pavers

$25 to $50 per square foot installed. The default choice on most Sungreen jobs, and for good reason: individual stones flex with frost rather than cracking, and a shifted paver is a ten-minute reset instead of a slab replacement. Joints between stones move water down through the base instead of letting it pond and freeze on top, which is the exact failure that ends poured concrete early in this climate.

Natural Stone and Flagstone

$35 to $75 per square foot. Flagstone tops the request list, usually 1.5 to 2 inch thicknesses for patio use. The premium is mostly labour. Irregular stone shapes need individual fitting and a craftier hand on the cuts, and that time shows up on the invoice whether the homeowner asks about it or not.

Plain Poured Concrete

$10 to $20 per square foot for the slab. Cheapest way onto a patio, and the trade-off is real: poured concrete cracks predictably in Calgary frost cycles, often within five winters of pour day. Control joints delay it, they do not prevent it.

Stamped Concrete

$20 to $35 per square foot. Looks terrific the first summer. The crack risk is the same as plain concrete underneath the pattern, and once a stamped slab does crack, the repair shows more than it would on a plain grey pour, since matching the stamp pattern and colour on a patch is close to impossible.

Permeable Pavers

$30 to $55 per square foot, above standard pavers since the open-joint design needs a deeper, more porous base underneath. Worth asking about on properties with drainage trouble already, since the surface itself does part of the drainage work instead of shedding every drop toward the yard.

Patio Cost by Size: 12×12, 20×20, and 24×30

National calculators average across a country’s worth of labour rates and material costs, which is why the number they produce rarely lines up with a Calgary quote. Running the per-square-foot bands above against the sizes homeowners actually search gets closer.

12×12 (144 square feet): $1,440 to $2,880 plain concrete, $2,880 to $5,040 stamped, $3,600 to $7,200 pavers, $5,040 to $10,800 natural stone.

20×20 (400 square feet): $4,000 to $8,000 plain concrete, $8,000 to $14,000 stamped, $10,000 to $20,000 pavers, $14,000 to $30,000 natural stone.

24×30 (720 square feet, closer to a large patio or covered concrete slab): $7,200 to $14,400 plain concrete, $14,400 to $25,200 stamped, $18,000 to $36,000 pavers.

A 20×20 concrete slab at standard 4 inch thickness needs roughly 5 cubic yards of concrete once waste and subgrade variation get factored in, a number that comes up almost every time someone is pricing the pour separately from the finish work. Those ranges assume a normal lot with reasonable access. Grade changes, curved edges, and integrated features push every figure toward its high end, sometimes past it.

What Drives Patio Cost Up or Down

Two patios at the same square footage can land thousands apart, and material only explains part of the gap.

Design complexity adds up fast. A straight rectangular patio is the most efficient shape to build. Curved edges, borders in a contrasting stone, and integrated features like steps or a fire pit ledge all add cutting time and material waste on top of the base price.

Site access changes the labour bill before a single stone gets placed. A backyard reachable straight off the alley moves fast. One that needs materials carried through a narrow side gate turns a two-day job into three, and that difference lands in the quote whether the homeowner asks about it or not.

Removal of an existing patio or slab is the line item most people forget to budget for. Tearing out old concrete and hauling it off runs a few hundred dollars on a small job, more once disposal fees and a rented bin get added, and it sits on top of whatever the new build costs.

Drainage and grading correction can add real money if the yard already sheds water toward the house instead of away from it. French drains, catch basins, or a full regrade before the patio even starts are not rare asks on Calgary’s older infill lots.

Lot type shapes the quote before material even enters the conversation. Bearspaw and Springbank acreage jobs usually mean longer material hauls and more grading, since the ground rarely arrives level. Killarney and Altadore infill lots run the opposite problem, tight side-gate access and mature trees close to the build zone, which slows the crew down even on a small footprint.

The Base Is Where a Calgary Patio Gets Won or Lost

Clay soil sits under most of Calgary, and clay holds water, which freezes and heaves. That single fact decides more patio failures than material choice ever does. Every Sungreen patio callback traces back to base depth, not the stones sitting on top of it.

A patio built to hold up here needs 100 to 150 millimetres of compacted gravel base, non-woven geotextile fabric underneath to stop silt from working its way up and softening the structure, and a setting bed graded to slope 6 to 12 millimetres per metre run, away from the house. Flat patios pond water. Ponded water freezes, and frozen water lifts whatever sits on top of it. Two quotes for the same patio can differ by thousands for one reason alone: one specifies real base depth and the other specifies whatever gets the number down. Ask every contractor what their base spec actually is. If the answer is vague, that vagueness is the answer.

Do You Need a Permit for a Patio in Calgary?

Usually not. A ground-level patio, no roof, no structural walls, generally sits outside the building permit process the way a deck over 0.6 metres does not. Grading and drainage are the exception. If the patio changes how water moves across the lot line or toward a neighbour’s property, the City wants to see that plan before the crew breaks ground. Sungreen checks this at the free site visit rather than leaving it for someone to discover later.

DIY vs Hiring a Calgary Patio Contractor

Materials alone, DIY is the cheaper path, and it is not close. A homeowner buying gravel, sand, and pavers directly saves the labour line entirely, which typically runs 40 to 50 percent of a professional quote.

What that math skips is the base. We get called out to fix heaved pavers, sunken corners, and pooling low spots from DIY builds every spring, and the repair bill on a failed base usually erases whatever the labour would have cost in the first place. A small, flat patio with easy access and no drainage complications is a fair weekend project for someone willing to rent a plate compactor and follow the base spec properly. Anything with a slope, a retaining element, or more than a couple hundred square feet is where hiring starts paying for itself.

Pavers vs Poured Concrete: Which Costs Less Over Time

Concrete wins on day one. Pavers cost more upfront but rarely need full replacement, since a shifted or stained stone gets lifted and swapped instead of the whole surface getting torn out. Poured concrete looks clean for a few seasons, then the freeze-thaw cracking starts, and once a slab cracks the repair options are limited to patching, an unattractive fix on a visible surface, or a full re-pour.

Over a fifteen-year horizon the two materials trade places on total cost more often than the upfront numbers suggest. It comes down to how much a homeowner minds the maintenance and how the yard actually gets used. A patio that sees a fire pit and furniture year-round earns back the paver premium faster than one that mostly sits empty.

Frequently Asked Questions

How much should a 20×20 patio cost?

$4,000 to $30,000 depending entirely on material, plain poured concrete at the bottom and natural stone at the top. Most 20×20 quotes we write land in the paver range, $10,000 to $20,000.

How much should a 12×12 patio cost installed?

$1,440 to $10,800 across the material range. A plain concrete slab that size runs closer to $1,440 to $2,880, while pavers sit at $3,600 to $7,200.

Is a new patio a good investment?

It holds value better than most backyard projects, especially built on a proper base that will not need redoing in five years. The return depends more on install quality than on which material gets chosen.

Is it cheaper to build your own patio?

On materials alone, yes, since labour is roughly 40 to 50 percent of a professional quote. Once base depth and drainage enter the picture, the savings shrink fast for anyone without plate compactor experience.

Is it cheaper to pour a concrete patio or use pavers?

Concrete costs less upfront, $10 to $20 per square foot against $25 to $50 for pavers. Pavers usually cost less over a fifteen-year span once cracking, patching, and eventual replacement on the concrete side get factored in.

How many yards of concrete would I need for a 20×20 slab?

Roughly 5 cubic yards at standard 4 inch thickness, once waste and subgrade variation get built into the order. Thicker pours or reinforced slabs need more.

How much does it cost to pour a 20×20 concrete patio?

$4,000 to $8,000 plain, $8,000 to $14,000 stamped. The gap between the two is almost entirely labour and the finishing work that goes into the pattern.

How much to pour a 12×12 concrete patio?

$1,440 to $2,880 plain, $2,880 to $5,040 stamped. Small footprint, so the per-square-foot rate carries almost the entire number, with little room for economy of scale.

What is the average cost of a new patio?

Across every project Sungreen quotes, the middle of the range sits closer to $8,000 to $12,000, a mid-size paver patio in the 250 to 350 square foot range. Plain concrete pulls the low end down, natural stone pulls the high end up, and most homeowners land somewhere between the two.

How much does a 24×30 concrete slab cost in Canada?

$7,200 to $14,400 plain, $14,400 to $25,200 stamped, using the same per-square-foot bands that apply to any Calgary pour. Provinces with cheaper labour markets shave a bit off the low end, but the material cost itself does not vary much coast to coast.
