Unilock Construction in Westminster, CA | Sycamore Contractors
We’re Sycamore Contractors, a Westminster General Contractor and independent Unilock installer serving the surrounding 1950s – 70s tract neighborhoods.

What makes our work here different is simple: we know the subsurface obstacles hiding under Little Saigon’s older commercial strips and mid-century residential lots before we ever break ground. Call (877) 265-6284 for a free estimate on any Unilock project in Westminster.
Why Westminster Residents Choose Us for Unilock Service
Westminster isn’t a generic suburban grid. It’s a city built in waves, from 1950s ranch houses to the post-1975 Vietnamese refugee resettlement that turned Bolsa Avenue into one of the most concentrated commercial corridors in Southern California. That history shapes every hardscape project. Older strip centers have plumbing and grease lines running where you’d least expect them. Residential lots have expansive clay soil that shifts with winter moisture. Our crews have worked these conditions long enough to know what holds up and what doesn’t. Nate Calloway, our owner, grew up in Temecula and built his trade on the principle that subsurface prep matters more than the paver you put on top. We bring the same Unilock product knowledge and OEM parts discipline to every Westminster job, whether it’s a residential patio in the 92683 ZIP or a storefront entry along Westminster Boulevard. As an independent installer, we’re not tied to a manufacturer’s sales agenda. We recommend what works for your specific site, not what’s easiest for us to sell. You can explore our full Unilock sales & service background to understand the depth of product knowledge behind our recommendations.

Common Unilock Construction Problems We Solve in Westminster
- Edge restraint failure on driveways with tight turning radii. We see this constantly on older Bolsa Avenue commercial strips where delivery trucks make sharp turns into narrow aprons. The lateral force pushes pavers outward, the edge restraint fails, and the driveway starts to spread at the edges. We re-set the perimeter with OEM Unilock edge restraints and add a deeper compacted base where truck traffic is a daily reality.
- Efflorescence on Brussels Block pavers. Westminster’s winter rains combined with irrigation overspray wick salts through the paver surface, leaving a chalky white film. North-facing walkways on residential properties in the 92684 ZIP are especially prone because they dry slower. We clean and seal affected pavers, then adjust drainage so water doesn’t sit against the surface.
- Settlement and ponding on patios over expansive clay soil. Westminster’s older neighborhoods were built when subgrade compaction standards were looser. Winter moisture causes clay to expand, summer drought causes contraction, and pavers shift. We fix this by removing the affected area, re-compacting with proper base material, and re-installing with Unilock joint sand that meets the system’s spec.
- Color fading and surface wear on Onyx pavers in commercial entries. Restaurant grease, cleaning chemicals, and heavy foot traffic along Westminster Boulevard accelerate degradation on darker paver lines. We assess whether localized paver replacement or a full re-sand and seal is the right call, always pricing the repair option first.
- Driveway replacement over aging utility lines. Many Westminster homes from the 1960s and 70s have original galvanized plumbing and shallow utility runs. A paver driveway replacement over those lines requires care: we verify what’s underneath before excavating, coordinate with plumbers when needed, and build the base to protect what’s below.
Unilock Service in Westminster: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a generic Unilock page: Westminster’s Little Saigon commercial corridors were built before today’s restaurant codes. Many older strip centers along Bolsa Avenue lack adequate grease interceptor capacity and venting, so tenant improvements frequently require underground grease-line and hood upgrades. Those lines run exactly where a paver driveway or patio often needs to go. On one Bolsa Avenue strip center, we replaced a cracked concrete driveway with Unilock Brussels Block pavers, but discovered an undersized grease interceptor line running directly under the proposed driveway apron. We coordinated with the tenant’s plumber to reroute the line, then installed a heavier compacted base and OEM edge restraints to handle delivery truck traffic. The result: no future settlement and the restaurant’s grease line stayed accessible. An out-of-town hardscape crew would have paved right over it. That’s the difference local knowledge makes in Westminster. For homeowners across the city, we’ve compiled everything you need to know about our Westminster service area coverage and what to expect when we work in your neighborhood.
Unilock Models & Products We Service in Westminster
We install and service the Unilock lines that perform best in Westminster’s coastal Southern California climate: Brussels Block for classic residential driveways and patios, Onyx for modern commercial entries and contemporary home designs, Beacon Hill for a tumbled, old-world look that suits mid-century ranch houses, and Elegance for a smooth, refined surface on high-end patios. We also offer Unilock service in Huntington Beach and nearby coastal communities. Our parts approach is straightforward: we use OEM Unilock edge restraints and joint sand because those components are engineered to work together as a system. For base materials, we source compatible aftermarket products that meet or exceed ASTM standards, which keeps your project cost reasonable without compromising performance. We stock common paver styles and edge restraints locally so Westminster projects don’t stall waiting on a shipment from the Midwest.

Your actual cost depends on square footage, access, existing subsurface conditions, and whether we’re removing old concrete or starting fresh. A standard residential paver driveway in Westminster’s 92683 ZIP typically falls in the $9,000 to $14,000 range once you account for the old surface removal and base prep. Commercial work along Bolsa Avenue runs higher because of delivery truck loading requirements and the subsurface coordination we discussed above. Every project starts with a free, written line-item estimate so you know exactly what you’re paying for before we start. Call (877) 265-6284 to schedule yours.

FAQs – Unilock Construction in Westminster
Technically yes, but we rarely recommend it. Westminster’s expansive clay soil moves, and a paver overlay on concrete will telegraph every crack and settlement line through the new surface within a few seasons. The right approach is removing the old concrete, compacting a proper base, and installing the Unilock system as designed. It costs more upfront but lasts decades longer. Call (877) 265-6284 and we’ll assess your specific driveway and give you an honest recommendation.
Winter rains in Westminster are mild compared to most of the country, but they expose two problems: poor drainage on flat residential lots and salt-wicking on north-facing surfaces. We address both during installation by setting proper base slopes, using geotextile fabric where needed, and recommending sealers on pavers prone to efflorescence. A correctly installed Unilock system handles Westminster’s rainy season without issue. For an exact quote on your property, call (877) 265-6284.
Onyx pavers are our most common recommendation for commercial entries along Bolsa Avenue and Westminster Boulevard, and we also install Unilock in Midway City. The smooth, modern surface handles heavy foot traffic well, and the color range complements both renovated and original storefronts. The key is what goes underneath: commercial entries need a deeper compacted base and OEM edge restraints rated for delivery truck loads. We spec these details on every commercial estimate. Call (877) 265-6284 to discuss your storefront.
Paver patios and walkways typically don’t require a permit in Westminster, but driveway replacements often do, especially if you’re changing the apron where it meets the street or altering drainage patterns. Our team checks Westminster’s current requirements for every project and handles the permit paperwork when needed. We’ve done this enough times in the 92683, 92684, and 92685 ZIP codes to know what triggers a review and what doesn’t. Call (877) 265-6284 and we’ll verify your specific scope.
A residential paver patio in Westminster typically takes 3 to 5 working days from excavation to final joint sand. A full paver driveway replacement runs 5 to 8 working days, longer if we’re coordinating with plumbers on subsurface utility reroutes like we’ve done on Bolsa Avenue commercial projects. We schedule all Westminster work with a written timeline and keep you updated as the job progresses. Call (877) 265-6284 for a project-specific timeline and free estimate.
