Unilock Driveway & Pavers: The San Antonio Owner’s Guide
Replacing or repairing Unilock driveway pavers in San Antonio typically runs $7,000 to $18,000 installed, depending on the square footage, the paver line you own, and what’s happening beneath the surface. We stock a range of Unilock-compatible pavers and can usually match your existing pattern within a few days of the first site visit. Most owners discover the problem the same way: a paver that has settled into a low spot, a crack running through a few units where a tree root pushed up, or a patch of color that no longer matches after a repair done with the wrong product line.
We’re Elmstead Remodeling San Antonio, a Cedarwell company. We are an independent service provider and not affiliated with Unilock, but we work with their paver systems regularly and we know how San Antonio’s clay soil and summer heat treat them. The written price you sign before the work starts is the price you pay, and the 365-Day Done Right Promise means if the repair is not done right, we make it right.

Which Unilock Models This Applies To
Unilock makes dozens of paver lines, and they are not interchangeable. The Brussels Block, Thornbury, Courtstone, Richcliff, and Beacon Hill Flagstone lines all have different surface textures, edge profiles, and paver thicknesses. A Brussels Block paver is 60mm thick with a tumbled, rounded edge. A Richcliff paver is thinner at 38mm and has a flatter, more architectural face. If you try to patch a Thornbury driveway with a Brussels Block, the height difference alone will leave a lip you can catch a shoe on.
The surest way to identify your line is to look at the back side of a paver you already have. Most Unilock pavers have the product name molded into the underside, though on older installs that stamp may be worn. If it is not visible, measure the thickness with a tape measure and take a close photo of the surface texture and edge shape. Send it to us or have us out for a site visit, and we can usually name the line from the walkway. For San Antonio driveways, we recommend staying with OEM Unilock units when the existing install is under 10 years old, because the color blend will still be in production and a close match matters. On older installs where the line is discontinued, a quality aftermarket equivalent in the same size and color family is often the better call than trying to force a mismatched OEM unit.
We also work with KraftMaid cabinetry, Cambria and Silestone countertops on the remodeling side of our business, but pavers are a different animal entirely, and Unilock is the brand we see most in San Antonio driveways and patios.
Signs Your Unilock Driveway & Pavers Are Failing
- A low spot or birdbath that holds water after rain. This almost always means the bedding sand or base underneath has washed out or settled. The pavers themselves are fine; the base is the problem. San Antonio’s heavy spring rains move a lot of water, and if the base was never compacted properly, it shows up within a few years.
- Cracked or spalled pavers in a single area. Spalling, where the surface flakes away, usually traces back to a point load, like a car parked in the same spot every day, or to pavers that were cut too tight against a rigid edge. Heat does not help. Our summers bake the surface, and a tight install without room to expand will fail at the edge first.
- A paver that rocks when you step on it. This means the bedding sand has migrated out from under that unit. It is a small problem today and a bigger one after the next rain, because water will follow the gap and wash out more sand.
- Color that does not match after a previous patch. If someone filled a hole with the wrong paver line or an older dye lot, the patch sticks out like a sore thumb.
- Sand washing out between the joints and collecting on the sidewalk. The polymeric sand in the joints has failed, or it was never installed. Every rain pulls a little more out, and now you see weeds taking root between pavers.

AfterReplacement Cost & What’s Included
In San Antonio, paver driveway installation runs $7,000 to $18,000, and most full replacements land between $10,000 and $14,000 for a two-car driveway. A repair that only addresses one settled area, a few cracked pavers, and re-sanding the joints usually falls on the lower end of that range. What drives the cost is square footage, the depth of the base you need, access for equipment, and whether we are matching an existing pattern or tearing out and starting fresh.
The price we write down before the work starts includes the pavers, the base material, labor, delivery, and the clean-up. Not the clean-up as a courtesy. The clean-up as a written line in the scope of work, with a photo of the finished job before the crew leaves. The 365-Day Done Right Promise covers the completed project. If something is not right after the job is done, we make it right. No one in San Antonio wants a second crew following the first one to fix a low spot.
DIY or Call Us?
If you have a single paver that rocks, you can safely lift it with a flat pry bar, check whether the sand underneath is still there, and set it back in. That is a 20-minute job and worth doing before it becomes a bigger one. What you should not do is start pulling pavers out of the middle of a driveway to fix a base problem. Once you open a section, the paver pattern locks the rest in place, and putting it back without the right sand and compaction tools means the repair will settle again within a season.
Tree roots and base washout are the two jobs we see homeowners start and regret. A root that lifted a paver usually needs more than a saw cut, and a base that washed out means the water problem is still there. We walk every job before we quote it, write everything down, and give you the number before any work begins. Call (432) 233-0976 and ask for the paver driveway team. A live person picks up.
FAQs
Unilock pavers themselves typically carry a transferable lifetime warranty against manufacturing defects, and with a properly compacted base they can outlast the house. The base is the part that fails first in San Antonio, usually within 5 to 15 years if it was cut thin or never compacted correctly. Call (432) 233-0976 and we will tell you honestly whether your pavers or your base is the problem.
Yes, if the failure is limited to a settled area, a few cracked pavers, or failed joint sand, a repair is usually the right call and costs less than a full replacement. If the base has failed across more than half the driveway, replacement often costs less per square foot than a patchwork of repairs. The free estimate and a look at the site will tell us which one applies to you.
A small repair with base work and re-sanding is usually done in one to two days, while a full driveway replacement typically takes three to five days depending on access and weather. We schedule around your family’s routine, not the other way around, and quiet tools during nap and school hours are part of how we work. Call (432) 233-0976 for a written timeline with your estimate.
We source Unilock pavers directly through their distribution network, and for current product lines we can usually have materials on site within a few days. Discontinued lines take longer to track down, and sometimes a color-matched aftermarket paver is the better option. We will show you samples and tell you what we found before you agree to anything.
If your Unilock driveway has a low spot, a cracked paver, or joints that keep washing out, call (432) 233-0976 and ask for a free estimate. We will come out, look at the site, write down the price before any work starts, and leave your driveway in better shape than we found it. Write it down, price it once, do it right.
