A 10x20 patio is 200 square feet in a long, narrow footprint, usually run along the back wall of the house, and in Winston-Salem, NC it prices better per square foot than a small square pad because the same crew visit covers more area. The shape has its own economics: forming a long rectangle is simple, concrete reaches it easily when it hugs the house, and it pairs naturally with a door landing. What moves your number is the slope of the yard along that 20-foot run, the finish, tear-out of anything already there, and drainage, because a pad against the house must shed water away from the foundation, not toward it. Written price before any concrete is ordered.

The 10x20 footprint usually sits against the house, which is the cheapest place to pour: short wheelbarrow runs, simple forming, no long haul across a yard. Cost per square foot lands meaningfully below a 12x12 because 200 feet absorbs the fixed crew costs better.
The shape stops saving money when the ground disagrees with it. A 20-foot run along a Piedmont backyard often crosses a grade change, and the low end has to be built up and compacted properly or the pad will hold water against the slab edge. That grading work, not the concrete, is the swing item on most 10x20 quotes.
Any patio touching the house has one non-negotiable: it must fall away from the foundation, about a quarter inch per foot. On a 10-foot depth that is a two and a half inch drop, built into the forms before the pour. Done right, rain sheets off the outside edge. Done wrong, water sits against brick and slab edge through every storm, and Winston-Salem averages measurable rain about one day in three. This is the first thing we check at the estimate and the first thing worth asking any bidder to show you in writing.
The pour itself is straightforward. These four items create the spread between bids.
