Unilock Construction in Houston, TX | Penhallow Remodeling Houston
We provide independent Unilock construction service across Houston: paver driveways, patios, retaining walls, and our Bathroom Remodeling in Houston and other outdoor living features. We’re not a manufacturer-authorized dealer, and we don’t pretend to be. What we are is a local Houston contractor that has torn out and rebuilt enough failed Unilock work to know exactly what this city’s clay soil and flood cycles do to pavers, and how to build them so they stay flat. Call (254) 527-5340 for a straight answer and a straight number.
Why Houston Residents Choose Us for Unilock Service
Trevor Nash started swinging a hammer on tract homes and gut-renovations back in the San Fernando Valley, where he learned early that a straight wall is harder to build than it looks. That lesson applies to pavers just as much as framing. Houston’s expansive clay soil doesn’t care what brand you bought; it heaves, it shrinks, and it will push a paver edge up into a trip hazard if the base wasn’t prepped for it. We know Unilock’s product lines well enough to spec the right unit for the right spot, and we know Houston’s soil well enough to build the base that keeps it there.
Our Unilock sales & service work covers everything from Brussels Block driveways in Meyerland to retaining wall rebuilds in Kingwood. Every job gets a written price before any work starts, a defined arrival window, and a written guarantee that follows the work. Background-checked, uniformed technicians show up when we say they will. And a live person answers the phone, any hour.

Common Unilock Construction Problems We Solve in Houston
- Clay heave lipping and trip hazards: Houston’s gumbo clay expands when wet and shrinks when dry. Without a deep, compacted gravel base, Unilock paver edges lift and lip, creating uneven driveways and walkways. We excavate the fat clay and rebuild the base properly.
- Post-flood sand joint washout: After Harvey and the heavy rain events since, we’ve seen sand joints wash out of Unilock patios and driveways across Houston, leaving pavers shifting underfoot and under vehicle loads. We rebed with polymeric joint sand that locks up better against standing water.
- Retaining wall bulges: Unilock retaining walls in Houston develop set-back bulges when hydrostatic pressure builds behind them. Undersized drainage stone and missing filter fabric are the usual culprits. We rebuild with proper drainage so the wall doesn’t lean forward after a heavy spring rain.
- Efflorescence on colored pavers: Houston’s heat and humidity accelerate efflorescence: that white, chalky deposit on Unilock concrete pavers like Copthorne and Mattoni. It’s not a structural failure, but it ruins the look, and it needs the right cleaning approach so it doesn’t come back worse.
- Uneven settlement over old trenches: In older Houston neighborhoods with pier-and-beam foundations and decades of utility work, we see paver fields settle unevenly over backfilled trenches. The fix is almost always a scrape-and-rebed, not a patch job.
Unilock Service in Houston: What Local Conditions Mean for Your Equipment
Here’s a fact that shapes Unilock work in Houston more than in any other major Texas metro: Houston has no zoning code. That zero-zoning policy means municipal utility districts, or MUDs, step in to regulate drainage and runoff in flood-prone watersheds. In practice, that means some Houston MUDs require permeable paver standards on residential lots, especially after Harvey-era flood mapping expanded. We prep Unilock bases to exceed local MUD infiltration requirements while avoiding code citations. If you live in the Meyerland area or anywhere along Brays Bayou, your lot likely sits in a floodplain overlay where this matters. Most paver contractors in Houston won’t mention MUDs until the inspector shows up. We bring it up before the first shovel goes in the ground, because it changes the base design and the drainage plan, and because a paver driveway that doesn’t drain correctly in Houston is just a future warranty claim waiting to happen.
Unilock Models & Products We Service in Houston
We work on Unilock Beacon Hill Flagstone, Brussels Block, Copthorne, and Mattoni lines regularly across the Houston service area. For full-depth color match and dimensional consistency, we spec genuine Unilock replacement units only. But for base and drainage components, we use premium local aggregates and non-OEM geotextiles, since Unilock doesn’t manufacture those site materials. Here’s our honest repair-versus-replace stance: if more than 20% of a Unilock field is cracked, spalled, or unevenly settled, we recommend a scrape-and-rebed rather than piecemeal repairs. Patching a failing base is throwing good money after bad, and we’d rather tell you that up front.

AfterUnilock Service Pricing in Houston
Unilock construction pricing in Houston depends on square footage, access, base depth, and whether we’re working with new units or rebedding existing pavers. Here are the ranges we quote most often:
| Service | Typical Houston Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
A paver driveway on expansive clay needs a deeper gravel base than the same job on sandy soil, and that’s usually the single biggest cost driver here. We give every homeowner a written price before any work starts, and that number holds. Call (254) 527-5340 for an exact quote; estimates are free.

FAQs – Unilock Construction in Houston
Yes, but it depends on how much vertical room you have at the door thresholds. In Houston’s slab-on-grade homes, the concrete slab usually sits 6 to 12 inches above grade. You can install Unilock pavers directly over the slab with a thin sand setting bed, but you’ll likely raise the finished surface 1.5 to 2 inches. If that’s too high, we can saw-cut and remove sections of slab or use a thinner profile paver. Call (254) 527-5340 and we’ll measure your thresholds and give you a written number.
That white, chalky deposit is efflorescence, and in Houston’s high heat and humidity, it forms faster than almost anywhere else in the country. Moisture moves through the paver, dissolves natural salts in the concrete, and leaves them on the surface when the water evaporates. It’s cosmetic, not structural, and it needs the right cleaning and sealing approach to keep it from recurring every summer.
They handle it only if the drainage was built right. Houston’s clay holds water against the back of a retaining wall, and without drainage stone and filter fabric, hydrostatic pressure builds until the wall bulges at the set-backs. We rebuild with a proper drainage layer and weep points so the water has somewhere to go.
They can, if the base is designed for it. Some Houston MUDs in flood-prone watersheds require permeable paving standards after Harvey-era flood mapping. We prep Unilock bases to exceed local MUD infiltration requirements, using open-graded base layers and wider joint spacing where the MUD requires it. Call (254) 527-5340 and we’ll check your MUD’s current standards before quoting.
Yes, it usually will. When a Kingwood home gets lifted for flood protection, the driveway and walkways are tied to the old grade, and the lift leaves them sloping away from the new finished floor height. We often rebuild the paver field at the same time as the lift, re-grading so the driveway drains away from the house and meets the new elevation cleanly.
