Concrete contractors typically charge anywhere from $6 to $14 per square foot. Cost factors include job size, site prep, base material, accessibility, your location, concrete finish, and concrete thickness. Removal of existing concrete, asphalt, deck, pavers, and grass will cost anywhere from $1 to $6 per square foot. Homeowners can often save money by removing and disposing of existing pavers, decks, and grass. Breaking up and hauling away concrete and asphalt is difficult and time-consuming without the proper equipment and may be worth having the pros do that work.

Concrete resurfacing is the process of applying a new, thin layer of concrete over an existing concrete slab to enhance its appearance and durability. The terms 'concrete resurfacing' and 'concrete overlay' are often used interchangeably, though the exact meaning can vary between contractors. Generally, both refer to applying a layer of pre-blended concrete, typically between 1/4-inch and 1-inch thick. Some contractors may use 'overlay' to describe a thicker application that adds structural integrity, while 'resurfacing' might refer to a thinner, more cosmetic layer. This process is a cost-effective alternative to completely replacing the concrete, as it uses significantly less material than pouring a new 4-inch slab. Resurfacing also provides an opportunity to add new colors or stamped textures. Other names for this process include concrete restoration, concrete refinishing, and concrete rejuvenation.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.
