Unilock Construction in Wilmington, CA | Rowan Construction Group Long Beach
Independent Unilock installation and repair in Wilmington runs $7,000-$18,000 for a paver driveway and $3,500-$11,000 for a patio, with most projects quoted in writing before work starts. If you’re also considering Wilmington Kitchen Remodeling, we can coordinate timelines. What separates our Unilock work here from jobs in Long Beach or Cerritos is the ground itself: Wilmington sits atop the Wilmington Oil Field, and that means methane mitigation, subsidence-prone slabs, and salt-laden port air shape every specification we write.

Why Wilmington Residents Choose Us for Unilock Service
We’ve been putting in Unilock systems across the Harbor area since 2007, and we’ve learned that Unilock sales & service in this market means knowing how Brussels Block behaves when the slab underneath it has settled two inches, or how Umbriano’s face holds up against refinery fallout. Grant Rowan, our owner, came up through Los Angeles Trade-Technical College’s framing, concrete, and finish carpentry programs before he ever ran his own job. That sequencing matters when your driveway needs both a paver field and a base rebuild that accounts for methane zone detailing.
We carry current Unilock OEM units and matching manufacturer-recommended polymeric sand in our local inventory. Colors and thicknesses tie into existing fields. For base, edge restraint, and geotextile, we spec quality aftermarket components because the difference is in gradation and compaction, not branding. Our crews are background-checked and uniformed; a live person answers calls 24/7; and every visit produces a documented photo record as standard, not an upgrade.
Under Clause 1 of The Haven Standard, the price is written before anyone starts. Under the 365-Day Done Right Promise, if it is not done right, we make it right. We’ve delivered 4,000-plus projects on that discipline.
Common Unilock Construction Problems We Solve in Wilmington

- Efflorescence and salt bloom on Umbriano and Beacon Hill surfaces. The Port of LA marine air keeps pavers damp and drives salts to the face. We see this worst where the original installer skipped sealing or used a generic sealer. Our fix: proper cleaning, OEM-compatible color-enhancing sealer, and a maintenance schedule that matches actual exposure.
- Polymeric sand joint failure after wet season. Standing water over a compromised base washes out joint sand, then pavers walk and shift. In Wilmington’s older slab-on-grade neighborhoods, the base is often the real culprit, not the sand. We diagnose whether re-sanding will hold or the base needs rebuilding.
- Edge restraint and base failure on settled slabs. Post-WWII bungalows off Avalon Boulevard and surrounding streets were poured before oil-field subsidence was fully understood. The pavers crack and course lines open because the sub-base moved, not because the Unilock failed. We rebuild with properly compacted aggregate base and steel or concrete edging that can handle the movement.
- Spalling and color loss on Richcliff and Brussels Dimensional near refineries. Diesel particulate and refinery fallout settle into textured faces. Aggressive pressure-washing abrades the surface further. We use low-pressure cleaning with appropriate detergents, then seal with a product rated for industrial-air exposure.
- Methane barrier damage during hardscape excavation. Any ground-disturbing work in most of Wilmington triggers LADBS methane zone requirements. A torn barrier or missing passive venting riser fails inspection and creates a safety issue. We coordinate soil-gas testing and barrier repair as part of the paver base scope, not as an afterthought.

AfterUnilock Service in Wilmington: What Local Conditions Mean for Your Equipment
Because most of Wilmington sits inside LADBS methane zone designations tied to the Wilmington Oil Field, hardscape work that disturbs the ground - a driveway tear-out, a new paver patio base, a walk expansion - can trigger methane barrier and passive sub-slab venting requirements that make the excavation portion look nothing like the same job in neighboring Carson or San Pedro. On a 1952 stucco bungalow off Avalon Boulevard near the harbor, we tore out a cracked, walking Unilock Brussels Block driveway that had been laid over an old slab; once we exposed the base we found the settlement and the methane detailing the LADBS zone map requires, so we rebuilt with properly compacted base, new edge restraint, methane-compliant venting, and a fresh Unilock field in a matched color. The homeowner’s complaint was “the pavers are failing” - the truth was the ground underneath them was, and the new field has stayed flat through two wet seasons.
That sequence is why we spec Unilock for Wilmington’s actual ground conditions, not a catalog photo. Salt-laden marine air from the port accelerates corrosion on steel edge restraints, so we use aluminum or thermoplastic where codes allow. Heavy diesel particulate means exterior paver sealers degrade faster than in cleaner coastal communities, so we specify products with higher solids content and shorter reapplication intervals. And the endemic slab settlement means we routinely find that a “paver repair” is really a base-and-drainage repair with pavers on top.
Unilock Models & Products We Service in Wilmington

We install and repair the full Unilock residential line, with current OEM stock for fast Wilmington turnaround:
- Brussels Block - tumbled paver, plus Brussels Dimensional and Dimensional Stone wall and coping systems
- Beacon Hill Flagstone and Beacon Hill Smooth - the textured and smooth-faced versions, with different sealing protocols for each
- Umbriano and Umbriano Smooth - slab pavers with exposed aggregate faces; the smooth variant needs different efflorescence management
- Town Hall and Richcliff - including current performance-version formulations with updated colorfastness specs
We buy current Unilock OEM units and matching OEM or manufacturer-recommended polymeric joint sand. For base, edge restraint, and geotextile, we spec quality aftermarket components. On a settled Wilmington driveway or patio we tell homeowners honestly when re-leveling and re-sanding the existing Unilock field will beat a full tear-out, and when the base is too far gone to save. No work proceeds on a change until the change order is signed - that’s the discipline that has kept our projects within a few percent of the agreed price since 2007.

FAQs - Unilock Construction in Wilmington
No. We are an independent installer and service provider, not a manufacturer-authorized dealer or representative. We source current Unilock OEM products and install them to manufacturer specifications, but we do not sell through Unilock’s dealer network or warranty their products on their behalf. Our workmanship warranty covers installation quality; material defects are handled per Unilock’s standard product warranty. Call (424) 567-7009 to discuss how this works for your project.
We use Unilock OEM pavers and manufacturer-recommended polymeric joint sand so colors and thicknesses match existing fields. For base aggregate, edge restraint, and geotextile, we spec quality aftermarket components because performance depends on gradation and compaction, not branding. We document every spec in the written quote so you know what you’re getting. Call (424) 567-7009 for the exact materials list on your job.
Most paver repairs run one to three days; full driveway or patio installations take five to ten days depending on base condition and whether methane zone work is required. Permitting through LADBS adds time if the project disturbs soil in a methane zone, which covers most of Wilmington. We build that timeline into the written schedule, not as a surprise. Call (424) 567-7009 for a specific timeline on your property.
We carry current stock for Brussels Block, Beacon Hill Flagstone and Smooth, Umbriano and Umbriano Smooth, Town Hall, and Richcliff including performance versions. For discontinued colors, we source from Unilock’s remaining inventory or recommend the closest current match with a transition detail. Can you match a Unilock color that was discontinued before you re-do my patio? Sometimes yes, sometimes no - we check Unilock’s remaining stock first, then propose a current color with a soldier course or inlay transition that makes the change look intentional rather than patched. Call (424) 567-7009 and we’ll check availability against your existing field.
Unilock paver driveway installation in Wilmington runs $7,000-$18,000 depending on size, base condition, and whether methane zone detailing is required. A simple overlay on stable base sits at the lower end; a full tear-out with base rebuild, drainage correction, and methane barrier coordination sits at the higher end. Every quote is flat and written before work starts. Call (424) 567-7009 for an exact quote - estimates are free.
