Why Houston Homeowners Choose Unilock Construction
Unilock paver installation and repair in Houston typically runs $3,500 – $18,000 depending on the scope, and most residential jobs take two to five days from tear-out to final sand. We provide Unilock repair in Houston as an independent construction service throughout the area, handling everything from single-section paver repairs on settled Brussels Block driveways to full Richcliff patio installations with proper base prep for our clay soils. As an independent Unilock service provider, we are not factory-affiliated, which means our recommendations come from what actually holds up in Houston’s flood-prone, expansive-clay conditions, not a manufacturer’s playbook.

Why Trust Penhallow Remodeling Houston for Your Unilock Construction?
We have pulled apart enough failed paver installations across Houston to know that the paver itself is rarely the problem. It is almost always what sits underneath. Our crew has reset Unilock Brussels Block driveways in Meyerland, Kingwood, and neighborhoods along Brays Bayou where the original installer skimped on base depth or skipped edge restraints entirely. Those are the jobs that fail within two seasons of Houston’s wet-dry clay cycle.
Trevor Nash runs our Houston operation as a General Contractor services leader, and he came up through the trades the old way. He studied construction technology at Los Angeles Trade-Technical College and spent years swinging a hammer on tract homes and full gut renovations before landing in Houston. That background means two things for your Unilock project. First, he reads the ground before he ever touches a paver. Houston’s expansive clay soils heave when wet and shrink when dry, and a paver driveway built on an undersized base will shift within the first year. Second, he gives you a written number before work starts, and he explains every line item. No vague hand-wave about base prep. You will know exactly what you are paying for and why.
Our technicians are background-checked and uniformed on every job. A live person answers the phone 24/7. And every Unilock repair or installation comes with our 365-Day Done Right Promise in writing: if the work fails inside the guarantee period, we come back and fix it at no charge. No service call fee, no re-inspection fee.

Common Unilock Construction Problems We Fix in Houston
Houston’s climate punishes paver installations harder than almost any other market in the country. The combination of expansive clay, relentless humidity, and downpour-driven drainage issues means certain failures show up here far more often than they do elsewhere. These are the most common problems we see:
- Settling and heaving on Brussels Block driveways. Houston’s clay soils expand when saturated and shrink during dry spells. A paver driveway built on a 3-inch sand bed instead of a properly compacted 6-inch limestone base will develop dips, ridges, and tripping hazards within two years. We regularly see Brussels Block driveways near Meyerland where a ten-foot section has dropped two inches because water pooled underneath during a wet spring.
- Edge restraint failure on Courtstone and Town Hall installations. When polymeric sand washes out during Houston’s heavy downpours, the outer course of pavers loses its grip. The pavers drift outward, gaps open, and the entire installation starts to spread. Cheap plastic edge restraints are the usual culprit. They flex, snap, or pull loose in our soil conditions.
- Efflorescence and color fading on older Unilock units. The white chalky residue you see on older Unilock patios is efflorescence, a mineral deposit that rises through the paver as moisture evaporates. Houston’s humidity and sun make it worse than in drier climates. It is not a manufacturing defect, and it does not mean the paver is failing, but it does signal a moisture problem somewhere in the base or the drainage plan.
- Joint sand erosion in low-lying areas. Any Unilock surface that stays wet after rain will lose the sand between the joints faster than the manufacturer’s generic guidance accounts for. Pavers start to wobble, weeds take root, and the surface loses its structural interlock. This is especially common in Houston neighborhoods that hold water after storms, like parts of Kingwood and the floodplain-adjacent streets near Brays Bayou.
- Paver wobble and weed growth from skipped base compaction. A paver that moves when you step on it means the base was never truly compacted, or the subgrade was too soft when the pavers went down. Weeds follow soon after because loose joints give seeds a foothold. It is a cheap fix if caught early. Left alone, the entire section has to come up and be reset.
Unilock Parts & Our Repair-vs-Replace Approach
Here is the straight story on parts. When we provide Katy Unilock service and repair an existing installation in Houston, we source genuine Unilock pavers from local dealers to match the existing color blend. Unilock’s production runs shift slightly over time, so an off-brand paver that looks close in a catalog will stick out badly next to a ten-year-old Brussels Block driveway. We do not take that risk. The pavers we set for repairs come from the same local supply chain the original installers used.
For base and edge materials, we upgrade. We spec crushed limestone and commercial-grade aluminum or steel edge restraints that outperform the generic bedding and plastic restraints many original installations used. In Houston’s clay, the base is everything. A paver is only as stable as what sits underneath it.
When it comes to repair versus replace, we give you an honest read. A small settled section with intact pavers gets rebuilt on a proper base. A driveway where half the pavers are cracked, faded past matching, and the base was never right in the first place is usually cheaper to replace than to keep patching. Trevor will give you the straight story on what you need and what it costs, either way.
Our Unilock Service Process – Step by Step
- 1
Diagnosis and site assessment. We start by looking at the whole installation, not just the spot you pointed at. That means checking base depth, drainage slope, edge restraints, and joint condition. On a repair job, we probe the subgrade to figure out why the pavers moved in the first place. Fixing the symptom without fixing the cause is how you end up paying for the same repair twice.
- 2
Written quote and scope. You get a written price before any work starts. The quote includes the specific Unilock product line, the base spec, the edge restraint type, the sand, and the labor. No verbal ballpark that changes at the done date. If we need to match existing Unilock pavers, we confirm availability and include the exact blend name in writing.
- 3
Repair or install with proper base prep. For repairs, we remove the affected pavers, re-grade the subgrade, compact the base in lifts, and reset the pavers on fresh bedding sand. For new installations, we build the base to spec for Houston clay, not for a dry climate somewhere else. That means deeper excavation, proper compaction, and edge restraints that hold.
- 4
Joint sand and final compaction. We sweep polymeric sand into the joints, compact the surface, and activate the sand according to the specific product’s instructions. For Houston’s rainy seasons, we use a polymeric sand rated for wet-climate performance so it does not wash out during the first overnight storm.
- 5
Walkthrough and warranty paperwork. We walk the finished job with you, show you what we did, and hand you the written guarantee. Every Unilock project carries the 365-Day Done Right Promise. If something shifts or fails inside that window, we come back and make it right at no charge.

AfterUnilock Products We Service & Install in Houston
We work with the Unilock product lines most common in Houston residential installations. Brussels Block is the workhorse we see in driveways across the city, known for its tumbled edges and broad color range. Courtstone and Richcliff show up on patios and walkways, especially in newer builds where homeowners wanted a more contemporary look. Town Hall is the choice for a formal, timeworn appearance on front walks and pool decks. We stock common base materials, edge restraints, and polymeric sand locally, and we source matching Unilock pavers through Houston-area dealers on a per-job basis to keep color blends consistent with your existing installation.
We Also Service These Brands
Our crew works across the full Remodeling brand range, not just Unilock. We service and install KraftMaid cabinetry, Cambria and Silestone countertops, and Kohler fixtures. When your project spans pavers, a kitchen, or a bathroom, one crew with one written guarantee keeps the whole thing coherent.
FAQs – Unilock Construction Service in Houston
Houston sits on expansive clay soils that shrink when dry and swell when wet. That constant movement pushes and pulls at anything sitting on top of it. A properly prepared base with a 6-inch layer of compacted crushed limestone distributes the load and minimizes movement. A thin sand bed does not. Most of the settled Unilock installations we fix in Houston were built on bases that would have been fine in a drier, sandier region, but were never going to hold under our soil conditions. Call (254) 527-5340 if your Unilock surface is showing dips or unevenness, and we will give you an exact fix plan and a written price.
You can usually repair a section if the pavers themselves are intact and the problem is local to one area. We pull up the affected section, re-grade the subgrade, rebuild the base, and reset the same pavers with new edge restraints and polymeric sand. If the base failure runs across most of the driveway, or if the pavers are cracked and faded past matching, a full replacement often costs less per square foot than piecemeal repairs. We will show you both numbers in writing and let you decide. Estimates are free.
No. That white residue is efflorescence, and it is common on Unilock pavers in Houston’s humid climate. Water moves through the paver, picks up minerals, and deposits them on the surface as the moisture evaporates. It is cosmetic, not structural. What it does tell us is that moisture is moving through the paver system, and that is worth checking. If the base is saturated or drainage is dumping water onto the surface, the efflorescence is a symptom of a larger problem. Call (254) 527-5340 and we will come take a look at the whole installation, not just the stains.
The answer is not more herbicide. Weeds grow between pavers because the joints have lost their sand and organic debris has settled into the gaps. We pull the old material out, refill the joints with a polymeric sand rated for wet climates, and activate it properly. Once the sand cures, it locks the joints so weeds cannot root and water does not wash the sand away during Houston’s heavy rains. It is a straightforward fix, and it also stabilizes the pavers against wobble. Call (254) 527-5340 for a written quote to re-sand and reset your Unilock surface.
We use genuine Unilock pavers sourced from local Houston dealers whenever we are matching an existing installation or repairing a section. Color blends shift between production runs, and off-brand pavers look wrong next to existing Unilock units. For base and edge materials, we spec commercial-grade aftermarket components like crushed limestone and heavy-duty edge restraints, because those outperform what many original installers used. You get genuine Unilock where it shows, and upgraded materials where it matters underneath.

On a home near Brays Bayou, we pulled up a settled Unilock Brussels Block driveway where the original installer had skipped a proper base, unlike our Unilock Construction in The Woodlands, TX standards. Our tech re-graded the subgrade, laid a 6-inch compacted limestone base, then reset the same pavers with new edge restraints and polymeric sand. The client had us back the next spring after a record wet winter, and there was not a single shifted paver. That is what proper base prep does in Houston. It is also why we write the base spec into every quote instead of leaving it vague.
