Unilock Construction in Westminster, CA | San Bernardino Contractors
We install and repair Unilock paver systems across Westminster, CA at (855) 473-5620, and the job here is different from almost anywhere else in Orange County. Most of our Unilock work in Westminster starts because a driveway or patio was laid over an unpermitted garage slab or a thin existing concrete apron, and the base was never built to handle what this city’s multigenerational lots actually put on top of it. We’re an independent contractor, not an authorized Unilock dealer, so the only thing our crews get judged on is whether the base prep and finish hold up.

Why Westminster Residents Choose Us for Unilock Service
Most of the Unilock installs we take over in Westminster came from someone who had pavers go bad three, four, five years after the first crew left. The pattern is almost always the same: too-thin base, no edge restraint that actually holds, and water running off a low-pitch roof straight into the joint line. We’re the ones who pull the failed work, figure out what the original installer missed, and rebuild it so it doesn’t move again. Ruben Castillo, our owner, grew up learning construction from his uncle, who reroofed and framed garages on a shoestring budget, and that early education in not cutting corners on anything structural stuck with him. We spec Unilock’s own matching edge restraint, wall caps, and polymeric sand where the profile demands it, and we use quality aftermarket base aggregate and geotextile where it performs just as well. Same crews, same accountability, no dealer markup on the name. Serving all three Westminster ZIP codes: 92683, 92684, and 92685.

Common Unilock Construction Problems We Solve in Westminster
- Heaved and rocked Brussels Block driveways over old garage slabs. Westminster’s 1950s-1970s tract homes came with attached garages, and a lot of those garages got converted to living space over the years. When pavers go over the old slab with a two-inch base, vehicle loads transmit straight through and chip the paver edges. We pull it, rebuild the base with proper aggregate depth, and reset the original units when they’re still sound.
- Efflorescence and displaced joints on Ledgestone wall caps. The marine layer here holds moisture against north-facing walls and wall caps for months at a time. That moisture wicks down into polymeric joints, drives white mineral staining, and loosens the sand bond. We rejoint with Unilock’s polymeric sand and address the drainage path that fed the water there in the first place.
- Sunken paver corners where roof runoff scours the joints. Flat and low-pitch roofs are standard in Westminster, and when downspouts discharge straight onto front-yard hardscape, the water blasts the joint sand out and undermines edge restraint. We see sunken corners on patios and driveways all over the 92683 and 92684 ZIP codes for exactly this reason.
- Pavers cut tight against converted garages and detached ADUs. Multigenerational living in central Westminster means a lot of added square footage, and much of it was permitted after the fact. Footing depth and drainage around these structures were rarely designed for paver loads. We grade and re-drain before we re-lay.
- Patios sliding toward a thin existing slab. Some Westminster homeowners try to extend a concrete apron with pavers, and without a proper transition and restraint, the paver field creeps. This is a base-and-restraint problem, not a paver problem, and it’s the first thing we look for on a call.
Unilock Service in Westminster: What Local Conditions Mean for Your Hardscape
Central Westminster’s front-yard hardscape is shaped by multigenerational living. Converted garages and detached ADUs often got built out before permits, quietly, and the concrete slabs and footings under those additions weren’t meant to carry a paver driveway or patio. When we tear into an older Unilock install here, we frequently find pavers sitting over an unpermitted slab with no compacted base, no geotextile, and no real edge restraint. That means our job isn’t just lifting and re-laying units; it’s bringing the subgrade and drainage into compliance first, then rebuilding the Unilock system on top of it. This is a Westminster condition, not an Orange County condition at large. It’s the reason a paver job here takes a little more probing up front, and why our free estimates include checking for exactly this before we quote a number.
Unilock Models & Products We Service in Westminster
We work on the Unilock profiles most common across Westminster’s tract homes and newer front-yard remodels: Brussels Block pavers, Beacon Hill flagstone-textured pavers, Town Hall pavers, and Heritage slab and Ledgestone wall units. For a re-lay or repair, we spec Unilock’s own matching edge restraint, caps, and polymeric sand where the profile requires it; for base aggregate and geotextile, we use aftermarket products that hold up to Westminster’s marine-layer moisture and thin slabs. If the base and restraints are sound, we lift, re-screed, and re-lay the existing units. If the subgrade or old slab beneath is failing, patching the surface just delays the second call. See our Westminster service area coverage for where we work in the city.

AfterUnilock Service Pricing in Westminster
Here’s what Unilock work runs in Westminster, using our current pricing for paver and hardscape scopes:

The biggest cost driver in Westminster is what we find under the existing pavers. An install over a clean, compacted subgrade runs at the lower end; a re-lay over an old garage slab or unpermitted ADU footing with drainage problems runs higher because we’re rebuilding the base, not just swapping units. Your free estimate includes a subgrade assessment and a written line-item quote. Call (855) 473-5620 for an exact number.

FAQs – Unilock Construction in Westminster
Yes, and it’s one of the most common jobs we take on in Westminster. We remove the pavers, break out or re-grade what’s needed, build a compacted aggregate base with proper geotextile, reset Unilock edge restraint, and re-lay the original units if they’re still sound. Call (855) 473-5620 for a quote on this exact repair.
It can. Converted garages often sit on slabs and footings that weren’t engineered for paver loads, and drainage around them is usually an afterthought. We assess the existing slab and grading before any base goes in, and if the subgrade needs compliance work, we handle it as part of the scope. Call (855) 473-5620 to have us take a look.
That white staining is efflorescence, and in Westminster it comes from marine-layer moisture sitting on north-facing wall caps and joints. We rejoint with Unilock’s polymeric sand and correct the drainage path so the water stops feeding the wall base. If the caps are the problem, we reset or replace them before rejointing.
Yes. We work routinely in the 92683 ZIP and throughout Little Saigon, and we also offer Unilock in Garden Grove with the same bilingual job-site communication that is part of how we operate here. Your family members or their contractor can work with our crew directly in Vietnamese without anything getting lost between languages.
Not usually. Fresh pavers need time for the joint sand to settle and any residual moisture to release. In Westminster’s coastal air, sealing too early can trap moisture and worsen efflorescence. We typically recommend sealing after the first full season unless the install is in a high-traffic driveway. Call (855) 473-5620 and we’ll tell you what’s right for your specific layout.
