Unilock Construction in Los Serranos, CA | Sycamore Contractors
We install and repair Unilock paver driveways, patios, and retaining walls throughout Los Serranos, including parcels backing onto Chino Hills State Park, and we also provide Unilock service in Chino. What sets our Unilock work here apart is that we read slope, drainage, and wildland-urban-interface defensible-space plans before we ever quote a paver layout. We’re an independent hardscape contractor, not a Unilock-authorized dealer, and we’ll tell you plainly what that means for material sourcing. Call (877) 265-6284 to schedule a free estimate on Unilock construction in Los Serranos.
Why Los Serranos Residents Choose Us for Unilock Service
Unilock is a brand we’ve installed across enough hillside lots to know its quirks: how Brussels Block handles full sun, how Beacon Hill Smooth wears under hard water overspray, and what U-Cara walls need when the terrain behind them isn’t flat. Nate Calloway, our owner, grew up in Temecula and spent two decades running crews across Southern California before building Sycamore Contractors. His view on hardscape is simple: do it right the first time, or you’ll do it twice in the July heat. That’s not a slogan. It’s what happens to paver work that ignores drainage on a Los Serranos hillside. We service the full 91709 ZIP, from Carbon Canyon Road parcels to the equestrian properties near the state park edge, and we also offer Pomona Unilock service with the same genuine units and compatible edge restraint on hand so repairs don’t stall waiting on a distributor.

Common Unilock Construction Problems We Solve in Los Serranos
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. Hillside irrigation overspray hits the paver surface, then Santa Ana wind cycles pull the moisture back out fast. The mineral salts left behind look like a white haze that won’t rinse off. We remove the bloom and adjust the irrigation throw so it stops feeding the problem.
- Edge creep and joint sand washout on steep driveways. Los Serranos driveways that pitch toward the street lose polymeric sand every rainy season, then the border units start to wander. We re-level, re-sand, and pin the edge restraint with adhesive so the apron stays put.
- Bulging or leaning U-Cara and Town Hall retaining walls. Wall face settlement on a graded slope usually means the original install skipped geogrid tie-backs. Slope load here is not a flat-lot garden wall problem. We rebuild with engineered reinforcement and proper drainage behind the wall.
- Ember staining and paver spalling near the state park boundary. Patios or driveway edges set inside the brush-clearance buffer take radiant heat and ash from nearby burn scars. Pavers spall, discolor, and crack. We replace the affected units and rework the layout so hardscape sits clear of the defensible-space zone.
- Joint sand failure after rain pooling. When a patio drains toward the house instead of away, the sand washes out in sheets. We correct the slope, re-sand, and add a drainage swale where the lot grade demands it.
Unilock Service in Los Serranos: What Local Conditions Mean for Your Equipment
Los Serranos parcels backing onto Chino Hills State Park sit inside a wildland-urban interface where the brush-clearance buffer and slope drainage plan govern where hardscape can go. A paver patio or wall here is often designed around a defensible-space footprint that no flatland Chino or Ontario lot has to satisfy. The practical result: your Unilock patio can’t simply hug the back fence line if that fence is 30 feet from the park boundary. We pull the WUI requirements, check the slope-stability report, and then lay out where the Brussels Block or Beacon Hill actually belongs. It changes paver dimensions, edge restraint choices, and sometimes the whole footprint. Skip that step and you get a beautiful patio that the fire authority makes you tear out in June.
Unilock Models & Products We Service in Los Serranos
We install and repair the Unilock product families most common on Los Serranos hillside lots: Brussels Dimensional Series (Brussels Block), Beacon Hill Smooth, U-Cara Multi-Face Wall System, and Town Hall. We spec genuine Unilock units and Unilock-compatible edge restraint and polymeric joint sand, not off-brand lookalikes, because color-match and dimensional consistency decide whether a repaired run blends into existing hardscape or looks like a patch job. That approach matters most on partial repairs: a driveway apron fix with the wrong paver tone is visible from the street. We also stock a working set of the common profile repair units locally for the 91709 area so turnaround doesn’t drag. When a wall or driveway is still structurally sound, we re-level, re-sand, and re-pin before recommending tear-out. Replacement is a slope-and-drainage decision, not a cosmetic one. If we’re bidding a paver driveway or patio as part of a larger Unilock sales & service scope, you’ll see those same principles carried through.

AfterUnilock Service Pricing in Los Serranos
Unilock work in Los Serranos generally runs on the following ranges. These are project-level numbers, and hillside access, retaining wall scope, or WUI-driven layout changes can shift the final figure. A free estimate gets you a written, line-item quote so you can see exactly what’s driving the cost.
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
What drives the cost here more than anything is slope preparation and drainage work. A flat-lot paver patio in Chino can go straight onto a compacted base. A Los Serranos lot pitched toward the street often needs retaining walls, swales, and engineered fill before the first paver goes down. Call (877) 265-6284 for an exact quote, estimates are free.

FAQs – Unilock Construction in Los Serranos
No, not typically. Parcels backed against the park fall under wildland-urban interface rules that require a brush-clearance buffer, and hardscape placement has to work around that defensible-space footprint. We review the WUI plan and set the patio edge back accordingly. Call (877) 265-6284 and we’ll walk your specific lot.
Driveways in Los Serranos that pitch toward the street take concentrated runoff during winter rains, and polymeric sand washes out of the joints. Once the sand goes, the border units lose lateral support and start to creep. The fix is re-leveling, re-sanding, and gluing plus pinning the edge restraint. Call (877) 265-6284 for an inspection and written quote.
Almost always, yes. Retaining walls on graded slopes in Los Serranos carry lateral earth loads that a flat-lot garden wall never sees. Without geogrid tie-backs and a proper drainage column, a U-Cara wall will bulge or lean within a few seasons. We won’t build one without an engineer’s stamp.
Concrete segmental pavers themselves are noncombustible, but your hardscape layout still has to respect the brush-clearance buffer and fire-access requirements for Los Serranos parcels. A paver patio doesn’t exempt you from WUI rules. We coordinate hardscape placement with the defensible-space plan before install.
If the wall is bulging but the units are intact, repair usually means rebuilding the wall with geogrid reinforcement and proper drainage behind it, not full replacement. If the bulge indicates slope movement, we’ll recommend a geotechnical look first. Call (877) 265-6284 and we’ll make an honest call on it.
