Why Houston Homeowners Choose Unilock Construction
We provide Unilock repair in Houston as an independent construction service, specializing in paver driveway installation, paver patio installation, and driveway replacement. Our crews have taken apart and rebuilt enough failed Unilock paver bases across Greater Houston to know that longevity here is won below the surface. We regularly correct base erosion, edge restraints, and drainage issues that shorten the life of Unilock systems, and we’re upfront about which repairs are worth doing on an independent basis.
Bradford Remodeling Co Houston is not affiliated with or authorized by Unilock. We’re an independent General Contractor services provider for Unilock, which means we work for the homeowner, not the manufacturer. When a Unilock system fails in Houston’s gumbo clay, we diagnose what actually went wrong under the surface and fix it with OEM pavers and commercial-grade base materials. Curtis Lane runs our crews, and he’s been reading Houston scopes of work for over a decade, from gut-rehab kitchens in Montrose to full structural repairs after storm season. He keeps a worn copy of the local building code on his truck’s center console, and his philosophy is simple: straight scope, straight number, that’s the whole conversation. Call (940) 289-7658 for a free estimate on your Unilock project.
Key Takeaways:
- Unilock paver failure in Houston is almost always a base problem, not a paver problem
- We’re an independent Unilock service provider, not manufacturer-authorized
- Every project gets a written price before work starts, and every completed job carries the 365-Day Done Right Promise
- We use OEM Unilock pavers for patch work to preserve color match and texture
Why Trust Bradford Remodeling Co Houston for Your Unilock Construction?
Unilock pavers are only as good as the base under them. That’s the first thing we tell every Houston homeowner, because it’s the truth our crews see on job sites week after week. A lot of contractors can lay pavers. Fewer understand what happens when Houston’s expansive clay soils start moving underneath them. Our technicians have rebuilt Unilock systems from the base up in neighborhoods across the city, including Unilock Construction in Jersey Village, TX, and they know the specific ways these products fail here: base settlement from clay that expands and contracts with seasonal moisture, polymeric sand washout from heavy rain, edge restraints that pull loose when water erodes the perimeter. We don’t guess at these problems. We excavate, inspect, and document what we find before any repair quote is written.
Every Bradford Remodeling Co Houston crew member is background-checked and uniformed, so you know exactly who’s walking onto your property before they arrive. We work under The Garrison Standard, the operating framework that’s governed our work since 2004: written price before any work starts, no numbers that move at the door, and a signed guarantee in your hand when the job closes. The 365-Day Done Right Promise covers every Unilock project we complete. If the work fails inside that window, we come back and correct it at no charge. That’s not a marketing line. It’s written into the scope of work you sign before we touch your driveway or patio.

Common Unilock Construction Problems We Fix in Houston
- Base settlement and paver sinking on expansive clay. Houston’s gumbo clay expands when wet and shrinks when dry, and Unilock systems without a properly engineered base will move with it. We see this most often on 1970s-2000s tract home lots in the suburbs, where slab-on-grade foundations and paver surfaces share the same shifting soil. When pavers sink, the problem is rarely the paver itself; it’s the base losing its structural integrity underneath. We excavate, rebuild with compacted crushed concrete and geogrid where needed, and re-set the pavers on a stable platform.
- Polymeric sand washout in Unilock joints. Houston’s heavy rains don’t just wet the surface; they channel water through the joints and carry the polymeric sand with it. Once the sand washes out, pavers shift, weeds take root, and the interlock weakens. We see this constantly on Unilock Brussels Block and Town Hall installations where the original base lacked proper slope or drainage. Fixing it means more than sweeping in new sand. We check the drainage path first, correct the grade if needed, then re-sand with a commercial-grade polymeric product that meets or exceeds spec.
- Edge restraint failure on Unilock driveways and patios. When edge restraints fail, the perimeter pavers spread outward, and the entire surface loses its tension. In Houston, erosion from storm runoff undermines the restraints, and eventually the edges start drifting. We’ve repaired this on Unilock Copthorne driveways where the original aluminum edging had been staked too shallow for the soil conditions. The fix is new edge restraints, properly spiked and buried, then re-compaction of the perimeter base.
- Efflorescence and surface staining on darker Unilock pavers. Hard Houston water and high humidity leave mineral deposits on Unilock Richcliff and other darker paver lines. It looks like a white haze, and a lot of homeowners assume the pavers are defective. They’re not. It’s salts from water migrating through the paver and crystallizing on the surface. Some of it weathers away naturally. What doesn’t we address with proper cleaning and, in persistent cases, a breathable sealer that doesn’t trap moisture in the paver.
- Pooling water on Unilock patios from flat grades. Houston has no topographical relief, and a patio that looks flat to the eye may not be flat to water. When water pools on a Unilock patio after a normal rain, the base is absorbing moisture it shouldn’t, and freeze-thaw cycles in winter (mild as they are here) plus constant saturation accelerate failure. We correct the grade when we rebuild, directing water away from the foundation and toward the drainage path the city wants to see.
Unilock Parts & Our Repair-vs-Replace Approach
For Unilock pavers themselves, we always recommend OEM replacement units. Color match matters, especially on older runs where dye lots vary from year to year. A patch job with off-color pavers looks like a patch job forever. We can source Unilock Brussels Block, Town Hall, Copthorne, and Richcliff units through local Houston supply houses, and we’ll match your existing pavers as closely as the current dye lot allows. Some fading on older pavers is unavoidable; we’ll show you the new unit against the old before we commit to the repair, so there are no surprises.
For non-branded components, our approach is different. Base rock, geotextile fabric, and polymeric sand aren’t Unilock products, and we don’t pretend they are. We use commercial-grade materials that meet or exceed the manufacturer’s install spec: compacted crushed concrete for base, non-woven geotextile fabric for separation, and high-quality polymeric sand for joints. We repair when the paver units themselves are still sound and only replace full sections when cracking, spalling, or fading is widespread. That’s the honest math. If your Unilock pavers are structurally intact, rebuilding the base is almost always cheaper than a full replacement, and it restores the surface to serviceable condition. Call (940) 289-7658 for a straight answer on whether your Unilock system is worth repairing.
Our Unilock Service Process – Step by Step
- 1
Diagnosis and written scope. We start by walking the site with you and documenting what we see: settlement, joint washout, edge spread, drainage problems. Then we write a scope of work with a fixed price, and you sign it before any tools come out. Nothing moves at the door.
- 2
Excavation and base assessment. We remove the affected pavers and dig down to the subgrade. What we find tells us what the repair needs: more compaction, a geogrid layer, better drainage, or a full base rebuild. We document what we find and show you photos so you’re not taking our word for it.
- 3
Base rebuild or repair. We install the base to spec: compacted crushed concrete, geotextile fabric where the clay is active, proper slope away from structures, and compacted lifts. This is where Houston Unilock systems live or die. We build it to survive the clay, the rain, and the heat.
- 4
Paver reinstallation and joint work. We re-set the pavers, replace any cracked or chipped units with OEM Unilock replacements, install new edge restraints, and sweep in polymeric sand. Then we compact the surface to lock everything into place.
- 5
Test and walk-through. We run water over the finished surface to confirm drainage, check the joints, and walk the perimeter with you line by line. You leave the job with a signed 365-Day Done Right Promise in your hand, and a clean site behind us.

FAQs – Unilock Construction Service in Houston
Houston’s expansive clay soils expand when wet and shrink when dry, and any base that isn’t engineered for that movement will eventually settle under paver traffic. Drier cities have more stable subgrades. Here, the clay moves with every rain cycle and drought cycle, which is why we rebuild bases with geogrid and compacted crushed concrete on most Unilock driveways we service. The repair is a base problem, not a paver problem. Call (940) 289-7658 for an exact quote on your driveway; estimates are free.
We can match Unilock Brussels Block closely using OEM replacement units, but older dye lots will not be a perfect match. Pavers fade with sun and traffic, and a brand-new unit will sit slightly brighter against a ten-year-old surface. We show you the new paver against the old before installing it so you know what to expect. If the mismatch bothers you, we can pull and blend pavers from a less visible area and lay the new ones there instead. Call (940) 289-7658 for a free estimate on your patch job.
We don’t just resand the joints. We check the drainage path first. If the grade is flat or slopes toward the pavers, water will keep channeling through the joints and washing out the sand no matter how many times you refill them. We correct the grade where feasible, then re-sand with a commercial-grade polymeric product that meets the manufacturer’s spec. On driveways, we also verify that edge restraints are intact, because that’s what keeps the whole system under tension. Call (940) 289-7658 to schedule a drainage and joint assessment.
Efflorescence is a white mineral haze on the paver surface, and it’s common on darker Unilock lines like Richcliff in Houston’s hard water and high humidity. The condition is cosmetic, not structural. If the base is sound and the pavers are not cracked or spalled, repair is better: we clean the surface and, if needed, apply a breathable sealer that doesn’t trap moisture in the paver. Replacement only makes sense when the pavers themselves are failing. Call (940) 289-7658 and we’ll tell you which side of that line your patio sits on.
We use compacted crushed concrete and geogrid, not Unilock base panels. On Houston’s expansive clay, a mechanically compacted stone base with proper drainage performs better over the long run, and it’s what we’ve seen hold up across years of seasonal moisture cycles. That said, if a homeowner specifically wants Unilock base panels installed per the manufacturer’s guidelines, we’ll scope it and price it accordingly. Call (940) 289-7658 for a written price on either approach.
Paver driveway installation in Houston typically runs $7,000 to $18,000 depending on size and base conditions. Paver patio installation runs $3,500 to $11,000. Driveway replacement, including tearout of the old surface and new base, runs $5,000 to $14,000. These are real price ranges we honor in writing. Here’s the line-item breakdown:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
