Concrete patio cost, and what size really changes

How concrete patio cost works

1. Set the size against the furniture, not the yard. The commonest regret is a patio that looked generous on paper and cannot hold a table with chairs pulled out. Lay the actual furniture on the grass and mark around it before anyone quotes. Square footage is the main price driver, so this is the cheapest moment to get the number right.
2. Decide the finish before you collect bids. Broom finish, exposed aggregate, colored, stamped and polished are different prices and different crews. Ask each bidder to quote the same finish so the numbers mean something, and get a sample or an address you can go and look at rather than a photograph.
3. Check the fall and where the water goes. A patio against a house has to shed water away from the wall, and a flat patio that ponds against a foundation is a damp problem waiting. Confirm the slope and where it discharges. This matters more on a patio than on a drive because the patio is usually the piece touching the building.
4. Ask about the transition at the house. Where the slab meets the wall there should be a separation so the two can move independently, and the finished level has to sit below any siding, threshold or weep detail. Getting this wrong is expensive later and costs nothing to get right on the day.
5. Confirm reinforcement and joint layout. Patios crack like everything else, and the joints are where the design hides them. Ask for the joint spacing and how it relates to the shape, especially at inside corners, which is where uncontrolled cracks start. On a stamped or colored slab the joint layout is part of the look, not an afterthought.

Concrete patios, other structures and water against the house

A patio is usually covered as an other structure, on the same sudden accidental test as a driveway. The more common claim is the indirect one: a slab that slopes towards the house and sends water into a basement or crawl space. Carriers treat long term seepage as maintenance rather than as a loss, so the drainage detail is worth getting right at the pour, and worth photographing if a contractor has just built it wrong and the water arrived immediately.

Common questions

How does concrete compare with paver patio cost?

Poured concrete is usually cheaper to install for the same area and pavers are easier to lift and relay if the ground moves. The honest comparison is over time and over how likely your soil is to settle, not over the first invoice, and a contractor who quotes both will tell you which they would put on your ground.

Does a covered patio cost much more?

Yes, because the cover is a structure with footings, posts, a roof and usually a permit, and that work is priced separately from the slab beneath it. Ask for the slab and the cover as two lines so you can see what each is doing and decide them independently.

Can patio finishes for existing concrete be applied later?

Often, through a resurfacing overlay, provided the existing slab is sound and not moving. It is a real option with a real lifespan and it is not the same as a new slab. Ask what the contractor will do if the old surface fails under the new one, and get the answer written down.

How thick should a patio slab be?

Patios carry people and furniture rather than vehicles, so they are normally poured thinner than a driveway, with the base still doing most of the work. If a hot tub or an outdoor kitchen is coming later, say so now: that part of the slab needs designing for the load before it is poured, not afterwards.

How much does a concrete patio cost?

It is priced per square foot like other flatwork, but with no vehicle loading the slab and base can be lighter, while the visible edge and finish make the labour share higher. That is why doubling the size of a patio does not double the price, and why changing the finish can move it more than changing the area.

What does concrete patio installation involve?

Setting the size against the furniture you will use, choosing the finish before collecting bids, building in a fall that sheds water away from the house, a separation where the slab meets the wall with the level kept below thresholds, and reinforcement with a joint layout that hides the cracks.
