Unilock Driveway & Pavers: The Houston Owner’s Guide
Unilock driveway and paver replacement in Houston typically runs $12 – $38 per square foot installed, with most partial rebuilds landing between $3,500 and $11,000 depending on the failure. We stock Unilock-compatible units, joint sand, edge restraint, and geotextile on our trucks, so most paver repairs in the Houston metro go from first call to finished job inside of three to five days. The way most homeowners discover they need this page: a paver cracked down the middle after a heavy truck rolled onto the driveway, a low spot that holds water after every rain, or edging that let go and sent the border row wandering into the lawn.
Which Unilock Models This Applies To
Unilock makes paver units in three general thicknesses: 60mm for pedestrian areas, 80mm for driveways and light vehicle traffic, and 100mm+ for commercial or heavy-load applications. The 80mm units are what we install on Houston driveways, period. If someone quotes you 60mm pavers for a driveway that sees a pickup truck or an SUV, walk away. That’s a spec mistake that shows up as cracked units within two or three years.
Series compatibility matters. Unilock’s Brussels Block, Courtstone, Estate Wall, Richcliff, Umbriano, and Il Campo lines each have distinct dimensions and interlock patterns. A Richcliff unit does not interlock with a Brussels Block from the same era. To identify what you have, flip a loose paver and look at the underside: Unilock stamps the series name and manufacturing code into the mold. If the stamp is worn past reading, take a photo of the top surface pattern and we’ll match it from our sample library.
On the OEM-versus-aftermarket question: Unilock runs tight mold tolerances, and we’ve seen aftermarket “compatible” units vary by a sixteenth of an inch on the interlock lip, which is enough to throw a running bond pattern off-line within four courses. We default to OEM Unilock units for patches and repairs. For full tear-out and rebuilds, we’ll present both options in the written scope, with the cost delta spelled out so you decide with your eyes open.

Signs Your Unilock Driveway & Pavers Are Failing
- Border units separating from the field. Edge restraint wasn’t installed or failed, and the border row is now drifting outward. In Houston’s gumbo clay, this is the number one failure we see: the soil expands with our wet seasons and pushes the edge course free.
- A low spot that ponds water after rain. The sand base settled unevenly, usually because the original install skimped on compaction or used improper base material. Standing water on pavers accelerates joint sand loss and invites erosion under the units.
- Hairline cracks across multiple pavers in a line. This is a pattern crack, not a single bad unit. It means the concrete pad underneath shifted, or a heavy vehicle overloaded a thin base. Patching is temporary; the fix is a local base repair.
- Joint sand washing out after every storm. If you see sand accumulating at the low end of your driveway after rain, the polymeric sand failed or was never used. Unsealed joints let pavers shift, chip, and eventually crack.
- Wobbling or rocking pavers. A unit that rocks underfoot has lost base support underneath one edge. It’s not a cosmetic problem. Left alone, rocking pavers chip at the corners and the damage spreads to neighbors.

AfterReplacement Cost & What’s Included
For Houston homeowners, paver driveway replacement runs $7,000 to $18,000 for a full teardown and rebuild. A partial repair, typically 80 to 300 square feet, lands between $3,500 and $11,000. Paver patios fall on the lower end at $3,500 to $11,000 installed.
What drives that spread: square footage, access, whether the existing base is salvageable or needs removal, and the specific Unilock unit you have. A Richcliff or Umbriano unit runs a higher material cost than a standard Brussels Block. Every Bradford Remodeling Co Houston quote includes a written, line-item scope: excavation and base prep, geotextile, base material and compaction, bedding sand, Unilock units, edge restraint, polymeric sand, and haul-off. No numbers move at the door. The 365-Day Done Right Promise covers every drive and paver job we complete: if the work fails inside a year, we come back and correct it at no charge.
DIY or Call Us?
Here’s the honest split. You can safely check a couple of things before you call. Confirm your paver thickness with a quick visual: a driveway should have 80mm units, not 60mm sidewalk units. Take a photo of the failed area. Clear leaves and debris away so you can see the full damage. That’s useful.
What you shouldn’t do is pull cracked pavers and try to reset them. A failing edge means the restraint system underneath is gone, and a paver you reset without fixing the base will fail again inside a year, usually worse. The danger here isn’t Springs-level: it’s a risk of spending a weekend and a few hundred dollars to build the same failure back into your driveway. Straight scope, straight number: that’s the whole conversation. Call us at (940) 289-7658 and we’ll send a tech who can identify your unit, measure the base, and hand you a written quote before anything gets touched.
FAQs
Unilock pavers installed on a proper compacted base in Houston typically last 25 to 40 years before a full replacement, with joint sand needing refresh every 5 to 8 years. That lifespan depends heavily on the base: a properly compacted 6 to 8 inch crushed stone base with geotextile is the difference between a 10-year driveway and a 30-year driveway. Call (940) 289-7658 and we’ll tell you which one you’re standing on.
Yes, in most cases a localized repair is smarter and cheaper than a full replacement. The repair involves removing the failed units, correcting the base underneath, resetting the pavers, and re-applying joint sand. $3,500 to $11,000 covers most Houston partial-driveway and patio repairs. If the base is sound, you’ll save real money over a teardown; call (940) 289-7658 and we’ll scope it honestly.
Most partial repairs in Houston take two to three working days from start to finish, including base correction and joint sand. A full driveway replacement typically runs five to seven days. Weather and the exact Unilock unit needed can add a day or two. Call (940) 289-7658 for a schedule estimate on your specific job.
