How much does a 12x16 shed slab cost in Winston-Salem?

(336) 608-5157Get Free Estimate

A 12x16 shed slab is 192 square feet, and in Winston-Salem, NC it prices like other small pours: the concrete is cheap, the crew visit is the cost, so the per-foot rate runs higher than big-slab rates and the swing items are grading and access. The first honest question is whether your shed needs concrete at all. A small resin or kit shed lives happily on a gravel pad. Concrete earns its cost when the shed is heavy, when a mower or equipment rolls in and out, when you want a floor that stays dry and level for decades, or when the manufacturer requires a slab for the warranty. If that is your shed, the pad is a one-day pour with a written price before anything is ordered.

Concrete Slabs

Does a shed need a concrete slab?

Three cases where concrete is the right base and worth the money: heavy sheds and prefab garages, anything with wheeled equipment rolling over the threshold regularly, and sheds you intend to power, insulate or work inside. A poured slab keeps the frame off wet ground, stays level instead of settling post by post, gives mice and moisture no crawl space, and outlasts the shed itself.

The honest other side: a light garden shed on well-drained gravel is a perfectly good setup at a fraction of the cost. We will tell you which one your shed is rather than pour concrete you did not need.

What a proper 12x16 shed pad includes

The pour is small but the standards do not shrink with it.

What moves the price

On a pour this size, the yard matters more than the concrete. Backyard access for the crew and barrow route, how much grading the spot needs, and tear-out of an old pad or deck are the items that separate quotes. Winston-Salem's sloped lots put many shed sites on a grade change, and building the low corner up properly in compacted lifts is the difference between a pad that stays level and one that follows the fill down.

Common questions

Is a gravel pad cheaper than concrete for a shed?⌄
Considerably, and for light sheds it is genuinely fine. Concrete wins on permanence, dryness and load. If the shed is heavy, powered or houses equipment, the slab pays for itself in the life of the floor.
Do I need a permit for a shed slab in Winston-Salem?⌄
The slab on your own property generally does not need a building permit under North Carolina's residential threshold. The shed itself can have its own rules depending on size and placement, and setbacks from property lines apply, so check the shed, not the slab.
How long before I can put my shed on a new slab?⌄
About a week for a light shed, and closer to the full cure for anchoring a heavy prefab building. The written estimate includes the wait time so the shed delivery can be scheduled against it.
