Get matched with top concrete resurfacing pros in Sheldon, MO

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

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.

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.

Whether resurfacing concrete is worth the cost depends on the condition of the underlying slab. Resurfacing can be a good option if the concrete is in decent condition with only minor issues like standard wear and tear, small cracks, chips, or discoloration. In these cases, resurfacing adds a protective layer that can extend the concrete's lifespan without the high cost of a full replacement.

However, if the concrete has significant damage—such as deep cracks, peeling, sinking, or is broken up—resurfacing may not be worth it. The new overlay is only as good as the concrete beneath it, and existing problems like peeling and cracks are likely to show through the new surface. In situations with severe damage, replacing the entire slab is often more cost-effective in the long run and will yield a better result.

To make the best decision, it's recommended to have a licensed concrete specialist inspect the damage and determine if resurfacing is the right choice for your situation.
