Unilock Construction in Placentia, CA | Ashbury Contractors
Unilock construction service in Placentia typically costs $3,500 – $18,000 depending on whether we’re installing a new paver patio, rebuilding a driveway, or repairing settled pavers. We’re an independent contractor serving all of Placentia’s 92870 and 92871 ZIP codes, and the one thing that makes our Unilock work here different is simple: almost every job is a tear-out of a 1950s – 70s concrete slab on a narrow tract lot, not a fresh install on open ground. Noel Quintero and our crew know exactly how Placentia’s clay-heavy basin soils and tight side-yard setbacks affect a Unilock base, and we build accordingly. Call (833) 467-4091 for a free estimate on any Unilock driveway, patio, or walkway project.
Why Placentia Residents Choose Us for Unilock Service
Placentia homeowners call us because we treat a Unilock installation as a structural job, not a landscaping job. That distinction matters more in this city than almost anywhere else in north Orange County, which is why our Fullerton Unilock service follows the same structural approach. The tract homes here, mostly built between the 1940s and 1970s, sit on expansive clay and silty soils that move with every wet winter and dry summer. A paver base built to a generic spec will settle, lip, and spread within a few years. We build to Unilock’s published base, bedding, and joint-sand specs, but we also build for Placentia specifically, meaning deeper aggregate where the soil drains poorly and pinned edge restraints where the old concrete curb would otherwise let pavers wander. Noel picked up his foundational construction skills through the construction technology program at Santiago Canyon College in Orange, and he’s spent more than two decades since diagnosing exactly these kinds of failures across Tustin and the surrounding cities. When a previous contractor’s Unilock work starts showing cracks, he’s the one neighbors call.
We’re a full-scope general contractor, which means your Unilock paver project doesn’t exist in a vacuum. If we’re replacing a driveway that butts against a garage slab that needs re-grading, we handle it. If a patio ties into a fence line or a retaining wall, we handle that too. One contractor, every trade. The same crew that specs your Brussels Block also knows how the roof drains onto it and whether the side-yard gate will still swing after the grade changes. That’s the Ashbury Contractors difference, and it’s why our Unilock sales & service work in Placentia tends to come from referrals, not search ads.

Common Unilock Construction Problems We Solve in Placentia
- Polymeric joint sand washing out of Brussels Block joints. Placentia’s hard water and years of hose-down cleaning dissolve cheap joint sand faster than most homeowners expect. Once the sand goes, weeds root in the gaps and paver edges start chipping under foot traffic. We pull the old sand, re-clean the joints, and re-sand with a polymer that holds up to Placentia’s water chemistry.
- Paver settlement and lippage at the garage apron. The classic Placentia failure. A 1960s ranch home on clay soil gets a paver driveway built over a 2-inch base instead of a proper 6-plus-inch compacted aggregate base. Within two wet winters, the apron sinks and the pavers trip everyone walking to the front door. We tear out the failed base and rebuild it so the grade matches the existing garage slab without a lip.
- Efflorescence and salt bloom on Brussels Dimensional Stone. That chalky white haze on a Placentia paver patio usually means water is wicking up through the pavers because the installer skipped a free-draining bedding layer. In Placentia’s semi-arid basin climate, the mineral salts in the soil concentrate and bloom on the surface every summer. We strip the affected pavers, correct the base, and re-lay them so the salts stay in the ground where they belong.
- Edge restraint failure on narrow side-yard walks. Many Placentia homes have side yards barely 5 feet wide, and contractors often reuse the existing concrete curb as an edge restraint to save time. It never holds. The pavers spread, the walk shifts, and the gate stops latching. We pin a proper edge restraint and re-lay the field so it stays put.
- Driveway aprons that puddle at the garage door. In Placentia’s older core near the downtown rail corridor, the original concrete driveways were poured before modern drainage standards. When we replace them with Unilock pavers, we re-grade so water drains away from the garage instead of pooling at the door. It’s a small change that saves a lot of drywall and flooring damage down the line.
Unilock Service in Placentia: What Local Conditions Mean for Your Equipment
Placentia is essentially built out. Nearly every Unilock driveway or patio we install here is a tear-out of an original 1950s – 70s concrete apron or a rear-yard slab on a narrow tract lot. That’s the defining constraint, and it changes how the work gets done. When we pull a cracked 1960s concrete driveway in the older core near the 57 and 91 freeways, we’re not starting from a clean slate. We’re matching grades to an existing garage slab that may have settled a half-inch over six decades. We’re working inside side-yard setbacks that Placentia’s plan-check process scrutinizes hard on nonconforming lots. And we’re dealing with expansive clay that requires a deeper, properly compacted aggregate base than a greenfield job in a newer city ever would. A paver contractor who doesn’t know Placentia will lay a thin base, reuse the old curb, and be gone before the first winter rain exposes the mistake. We build for this city’s soil, its lot sizes, and its plan-check realities, because that’s what actually determines whether the pavers are still flat in ten years.
Unilock Models & Products We Service in Placentia
We install and repair the full range of Unilock segmental paving systems across Placentia, including Brussels Block, Brussels Dimensional Stone, Beacon Hill Flagstone, and the permeable Town Hall paver. Brussels Block remains the most common paver we see on Placentia driveways and patios, and its tumbled, dimensionally varied edges mean color matching requires sourcing through an authorized Unilock dealer. That’s exactly what we do. We buy Unilock pavers and matching edge restraints through the dealer network so the color and dimensional tolerance line up with the existing field, not just close enough to pass from the curb. OEM-grade matching matters when you’re repairing one settled section of a larger driveway and don’t want a visible patch. We specify ASTM-graded base aggregate and a quality polymeric sand rather than cheapest-available substitutes, because the joint sand is what fails first in Placentia’s climate.

AfterUnilock Service Pricing in Placentia
What you’ll pay for Unilock work in Placentia depends mostly on what’s underneath the pavers you already have, or what we need to build under the ones you want. Here are the line-item ranges we quote from:
| Service | Placentia Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
The biggest cost driver is the base. On a Placentia tear-out where the original concrete and sub-base are both shot, excavating and rebuilding a proper compacted aggregate base takes more labor and material than laying pavers on a fresh compacted pad. If the base is sound and we’re just re-sanding joints or resetting a settled edge, the job lands on the lower end. Every free estimate includes a written line-item quote, and we tell you before we start whether the base is salvageable or needs a full rebuild. Call (833) 467-4091 to schedule yours.

FAQs – Unilock Construction in Placentia
Yes, in most cases we can source matching Brussels Block through Unilock’s dealer network and repair only the settled section, provided the base underneath is still sound. Color variation between production runs exists, so we blend new pavers with the existing field rather than patching in a visibly different section. If the base has failed, a full tear-out and rebuild of that section is the honest answer. Call (833) 467-4091 and we’ll assess your driveway and tell you which path applies.
In Placentia, replacing an existing driveway with Unilock pavers at the same grade and footprint typically does not require a building permit, but any change to grade, drainage, or the driveway’s footprint can trigger plan-check review. Placentia is a built-out city where many lots are nonconforming under current zoning, so the city looks closely at anything that affects setbacks or drainage. We’ll tell you during the estimate whether your specific project needs a permit, and we pull it if it does.
Weeds in Unilock joints in Placentia almost always mean the polymeric sand has washed out or degraded, which happens faster here because of hard water from hose-downs and the city’s hot, dry summers baking the sand until it cracks. The fix is removing the old sand, cleaning the joints thoroughly, and re-sanding with a polymer formulated to hold up to Placentia’s water chemistry. If the base is also failing, re-sanding alone won’t solve it.
For the narrow rear yards common on Placentia’s 1950s – 70s tract lots, Unilock pavers usually win because they handle the expansive clay soil better than a monolithic slab, and we bring the same expertise to Unilock repair in Yorba Linda. A concrete slab will crack as the soil swells and contracts with winter rain and summer heat. Pavers flex at the joints, which means they move with the soil instead of fighting it. They also drain better, which matters on flat Placentia lots with nowhere for stormwater to go. Expect to pay $3,500 – $11,000 for a paver patio depending on size and base conditions.
Garage-to-ADU conversions are one of the most common projects in Placentia right now, and they create a specific sequencing problem for paver work. The driveway often needs to serve as a construction access path while the ADU is being built, then get re-graded and surfaced before final inspection. We coordinate the paver schedule around the ADU construction so we’re not laying a finished driveway that then gets driven over by a concrete truck. Expect to plan for a Placentia service area project like this as a phased job, and call (833) 467-4091 so we can sequence it properly with your ADU contractor.
