Unilock Construction in Westminster, CA | Moreno Valley Builders
We provide independent Unilock paver installation, repair, and re-sanding across Westminster, CA, including the 92683, 92684, and 92685 ZIP codes, and we also handle Unilock in Garden Grove. What makes our Unilock work different here is that we understand how Little Saigon’s dense lots, accessory dwelling conversions, and coastal marine layer affect paver performance in ways a spec sheet never will. We’re not a Unilock-authorized dealer, and we’re upfront about that. We’re a full-scope general contractor who installs and services Unilock systems because the product is good, not because a territory agreement says we have to. Call (877) 752-3154 for a free estimate on paver driveways, patios, or repair work in Westminster.
Why Westminster Residents Choose Us for Unilock Service
Noel Trevino, our owner and general contractor, grew up in Sunnymead Ranch and has spent nearly three decades tearing out and redoing the kind of work that fails on tight Southern California lots. He’s seen what happens when pavers are laid over poorly compacted base, when edge restraints aren’t pinned deep enough, and when drainage gets treated as an afterthought. If the details aren’t right on paper, they won’t be right in the wall. Or in the paver bed, for that matter. That’s the lens we bring to every Unilock job in Westminster.
We carry genuine Unilock units for color-matched repairs, and we stock polymeric joint sand, edge restraint, and compacted base material locally so we’re not waiting on a supplier run from across the county. Westminster homeowners choose us because we give straight answers: can the pavers be saved, or does the sub-base need to come out? We’ll tell you honestly, even when the cheaper answer is the better one. Our Unilock sales & service experience covers new installs and tear-out-and-rebuild scenarios in equal measure.
As a licensed general contractor, we manage the whole job under one roof. That means when your Unilock driveway ties into a converted garage entrance or a backyard patio butts against a new ADU foundation, we coordinate the concrete, drainage, and hardscape without you juggling three different subs.

Common Unilock Construction Problems We Solve in Westminster
We see the same handful of failure patterns repeated across Westminster. The good news: most are repairable without a full tear-out. The bad news: the longer they sit, the worse they get. Here’s what we typically find:
- Efflorescence and sub-base saturation. Westminster’s marine layer hangs around for parts of the year, keeping pavers damp longer than inland cities. On dense lots with sloped hardscape and minimal drainage clearance, Unilock’s dense-face blocks can wick moisture upward and bloom with white salt deposits that don’t brush off. The fix usually involves correcting drainage, not just scrubbing the surface.
- Lateral creep on narrow driveways. Tight setbacks in Westminster mean driveways double as turn-around zones. Vehicles cut hard, torque the outside edges, and before long the joint sand is gone and Brussels Block units start migrating outward. We see this constantly where edge restraints were installed too shallow or skipped entirely.
- Surface spalling after Santa Ana events. Wind-driven debris and the rapid dry-out that follows a Santa Ana can chip the tumbled edges of Unilock’s Beacon Hill and Thornbury lines. It’s cosmetic at first, but chipped corners become trip hazards in walkways and patio thresholds. One or two units we can replace. A whole field of them is a different conversation.
- Joint sand washout around accessory structures. Westminster’s winter rain, combined with runoff from added exterior staircases and converted garage units, erodes polymeric sand faster than a standard subdivision lot would ever see. The added impervious surface concentrates water flow, often aimed directly across a paver path or driveway swale.
- Weed growth and loose units on sloped areas. Once joint sand washes out, moisture follows, then roots. Westminster’s older housing stock often has backyard grade changes that weren’t addressed when the original concrete was poured, let alone when pavers went in decades later. Re-sanding without addressing the grade just sets the problem up to return.
Unilock Service in Westminster: What Local Conditions Mean for Your Hardscape
Here’s the part most people don’t realize until the city letter arrives. In Westminster’s Little Saigon corridor, many Unilock driveway and patio projects double as the front entry for a converted garage or back unit. That means the hardscape isn’t just a cosmetic surface. It’s part of an accessory structure’s stormwater footprint. Westminster’s code review for ADUs and garage conversions looks at impervious-surface limits on the lot, and a sprawling paver patio that looks great from Bolsa Avenue can push a property over the allowable coverage if nobody accounted for drainage. We’ve learned to check this before the first unit gets set. On a narrow lot off Bolsa, our crew replaced a failing Brussels Block driveway where tree roots and poor sub-base had caused widespread paver migration and joint sand washout. We excavated to a compacted Class II base, reset the Brussels Block field, anchored edge restraints, and re-sanded with polymeric joint sand. The drainage was tied into the existing swale so runoff stops pooling against the converted garage entrance. That’s the kind of project a generic hardscape crew misses because they’re not thinking about the ADU ordinance. We are. Serving Westminster is part of our broader Westminster service area footprint, and we treat every lot as its own drainage micro-case.
Unilock Models & Products We Service in Westminster
We install and repair the Unilock lines that show up most often in Westminster’s 1950s-to-1970s tract housing and Bolsa-area commercial strips. Brussels Block is the workhorse: a tumbled paver that handles driveways well when the base is correct. UniLock Brussels Dimensional gives a cleaner, more contemporary edge for patio borders and walkway bands. Beacon Hill and Thornbury are popular for backyard patios and sloped walkways, though Thornbury’s larger format needs a flatter surface to lay properly. We source genuine Unilock units when a repair demands exact color and profile matching, but we’ll recommend dimensionally compatible aftermarket pavers for hidden courses or base-layer applications where the budget matters more than the brand stamp. Our stance is repair-first whenever the base is sound and only a handful of units have chipped or drifted. Full replacement only when sub-base failure or widespread efflorescence means patching would be throwing money into a losing fight.

AfterUnilock Service Pricing in Westminster
Pricing is driven by two things: access and what’s underneath the pavers. Westminster’s narrow driveways and zero-lot-line setbacks mean material staging and excavation take longer than a wide suburban lot in Moreno Valley or a straightforward Unilock in Midway City job. And until we pull a few units, we don’t fully know if the base is salvageable. A free estimate from us includes a walk-through, drainage review, and a written line-item quote so you know exactly what’s included:
| Service | Typical Westminster Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
Every quote is fixed once we agree on scope. No change orders because we discovered something we should have caught in the estimate. Call (877) 752-3154 to schedule your free estimate, and we’ll tell you what you’re actually working with.

FAQs – Unilock Construction in Westminster
Yes, if the base is sound and the pavers haven’t cracked through. We pull the affected units, inspect the sub-base, re-compact where needed, replace any chipped or spalled pavers with genuine Unilock matches, and re-sand the entire field with polymeric sand. If the base has failed, re-sanding alone will look good for a season and then fail again. Call (877) 752-3154 and we’ll tell you which situation you’re in.
Often yes, especially if the driveway serves a converted garage or an ADU access path. Westminster reviews impervious-surface coverage on lots with accessory structures, and a new paver driveway can trigger a drainage review if it changes the lot’s stormwater footprint. We pull required permits and coordinate with the city on drainage requirements. Estimates are free at (877) 752-3154.
That’s efflorescence, and in Westminster it’s driven by the marine layer keeping pavers damp for long stretches. Moisture wicks through the paver, evaporates at the surface, and leaves salt deposits behind. The real fix is usually drainage correction beneath and around the paver field, not just surface scrubbing. We’ll assess whether it’s cosmetic or structural. Call (877) 752-3154 for a site visit.
In some cases, yes. If the concrete slab is structurally intact and the grade allows added height without creating drainage problems or tripping hazards, we can overlay Unilock pavers with the right setting bed and edge treatment. Cracked or badly settled concrete goes first. Call (877) 752-3154 and we’ll tell you which side of the line your driveway falls on.
For slopes under about a 5% grade, Brussels Block handles the subtle contour well. On steeper yards, we often combine Thornbury for the main field with a segmented edge layout to hold the pattern tight. The real answer depends on drainage direction and what’s at the bottom of the slope. Call (877) 752-3154 for a free estimate and we’ll spec it properly.
