The cost of a concrete slab generally falls between $3 and $10 per square foot, depending on factors like the thickness of the slab and whether frost walls are included or the slab is floating. For a 500- to 1,000-square-foot house, you can expect to pay around $5,318 for your slab.
When making pricing decisions — such as choosing between a 4-inch, 5-inch or 6-inch slab — factor in what type of furnishings and interior structures you will put in the house.

Cleaning your concrete slab properly involves having the right chemicals for the job, such as concrete cleaner, degreaser and micro-degreasers, among others. You may also need a wax stripper and special equipment. For these reasons, it’s a job best left to the pros.
Because unsealed concrete is porous, it readily absorbs liquids, leading to unsightly stains and freeze-and-thaw cycle damage. For this reason, it’s important to seal concrete that will see spills or outdoor weather.
The best option for garage floors and other high-traffic areas is epoxy, which forms a hard and extremely durable surface on top of concrete. Epoxy, acrylic, and polishes are often used on indoor floors, while acrylic-resin sealers and reactive penetrating sealers are used on outdoor surfaces to repel water and salt. Locate a concrete contractor in your area to help find the best solution.
Here are some examples of average costs:
- The national average cost to hire a concrete specialist is $2,750, but that price can vary greatly depending on the work needed to repair and resurface your concrete driveway, the square footage of the project, current costs of concrete, and regional labor rates.
- Driveway contractors average $2-$3 per square foot to smooth and resurface your asphalt driveway.
- Resurfacing concrete driveways averages $3-$10 per square foot. Pricing can depend on repairs needed, project size and geographic location.
- Nationally, the average cost for resurfacing a 500-square-foot driveway ranges from $2,000 to $5,000.
- Sealant for a concrete drive can cost $20-$80 per gallon.
- Sealant for an asphalt drive averages 25 cents per square foot.
The best finish for concrete floors depends on your personal taste. An acid stain is a bold, varied look with lots of texture and the potential for earthy tones and a natural stone appearance. A water-based stain might not last as long as an acid stain, but it gives you the choice of many different colors. Epoxy is great for high-traffic areas, kitchens, bathrooms, basements and garages. It provides a glossy, damage-resistant, non-slip coating on your concrete floors. To find out which finish is the best for your concrete floors, contact a concrete contractor near you.
A concrete paint cover is typically opaque and covers up the color of the concrete. This means it provides significant protection to the concrete below. However, if it is improperly applied or subjected to heavy traffic, a painted concrete floor is likely to chip and peel.
Epoxy and staining are two types of concrete floor sealer. Epoxy is a more durable but often more expensive option than a concrete stain. Epoxy forms a protective layer, while concrete stain is more decorative and requires more maintenance. Because epoxy can be more expensive than concrete stain, it is best used in high-traffic areas or in applications where low maintenance is desired.
A concrete stain, on the other hand, is quick to apply and can show off the textures of the concrete, but it does not provide a high degree of protection for the concrete against spills, salt, water and other contaminants. Staining concrete generally requires a dust mop, a pH-neutral cleaner and water to clean, while epoxy can cause resin buildup that necessitates the use of special detergents.

Concrete contractors can build foundations, structures, driveways, concrete storm drains, raise or level concrete patios and much more. They can handle every step of the process, starting with framing the mold that the concrete is poured into. They then cut, assemble and tie together the rebar, giving the concrete its tensile strength. Finally, they pour the concrete in, mixing and conditioning it to ensure it cures properly. They will also take steps to ensure that no air pockets are trapped within it.
