Unilock Construction in Los Serranos, CA | Daly City Construction
We handle Unilock paver and wall installation, repair, and replacement across Los Serranos, CA, from Brussels Block driveways to engineered Beacon Hill retaining walls. What sets our work apart here is direct experience with the Chino Hills foothills – the expansive clay, the graded pads, and the drainage demands that flat-lot contractors never see. If you’re planning a paver driveway, patio, or retaining wall in Los Serranos, call (866) 505-5254 for a free estimate from a team that knows this ground.

Why Los Serranos Residents Choose Us for Unilock Service
Noel Cabrera grew up in the Westlake district of Daly City, where he spent summers watching his uncle re-frame a garage and decided that was the kind of work he wanted to do with his hands. He trained in construction technology at City College of San Francisco before putting in years swinging a hammer on residential and light commercial jobs across San Mateo and San Francisco counties. That background shapes how we approach every Los Serranos General Contractor project – we look at what the house and the grade actually need, not what a catalog says should work.
We’ve installed Unilock pavers and walls on dozens of hillside properties across Los Serranos, and that repetition matters. We know how Brussels Block handles a two-story stucco home’s drainage patterns, how Beacon Hill walls perform when the Santa Anas hit, and where joint sand goes missing after a wet winter. As an independent contractor, we’re not bound to any manufacturer’s playbook – we recommend the Unilock product that fits the site, use genuine Unilock pavers and wall units for color and dimensional match, and tell you honestly when repair beats replacement. Our Unilock sales & service work covers everything from new installation to base correction and wall rebuilds.

Common Unilock Construction Problems We Solve in Los Serranos
- Paver settlement and heaving along driveway edges. Graded lots in Los Serranos often have fill sections that weren’t compacted to the standard a paver base demands. We see this constantly – driveway edges drop an inch or two after the first rainy season. We excavate, re-compact the base, and reset the pavers with stabilized joint sand.
- Uneven surfaces and joint sand loss after winter rains. Los Serranos’ expansive clay soils swell when wet and shrink when dry. That movement pushes pavers out of plane and forces joint sand to migrate. The fix is a properly prepared base with appropriate drainage, not just sweeping more sand into the joints.
- Scratched and chipped wall caps after Santa Ana wind events. Exposed hillside installations in Los Serranos take the full force of Santa Ana-driven debris. Wall caps on Beacon Hill and Lineo walls catch the worst of it. We replace damaged caps with matching Unilock units and can recommend edge details that reduce future impact.
- Leaning or cracking retaining walls. Walls built without adequate drainage behind them fail as the clay expands and contracts. We see this pattern after every heavy rain season in Los Serranos – walls start to lean, cracks open at the block joints, and the owner is left with a structural problem, not a cosmetic one. We rebuild with proper drainage and engineered backfill.
- Base movement under Unilock pavers on newly cut pads. When hillside homes in Los Serranos get new hardscape, the subgrade is often a mix of cut and fill. Unilock pavers installed over that without soil correction shift within a year or two. We correct the subgrade before the first paver goes down.
Unilock Service in Los Serranos: What Local Conditions Mean for Your Equipment
Los Serranos sits in the rolling foothills of the Unilock service in Chino area, and the city’s hillside grading ordinances require engineered drainage and slope stabilization for hardscape projects. That’s not a suggestion – it’s a permitting reality. So Unilock installations here often need permitted retaining walls and subsurface drainage that flat-lot cities don’t mandate. A paver driveway in Los Serranos isn’t just pavers on a bed of gravel. It’s a system that has to manage water moving downhill, clay that swells, and a grade that wants to settle. The 91709 zip covers homes built from the 1980s through the 2000s on graded pads, plus older ranch-style properties along the valley floor. After heavy winter rains, hillside homeowners in Los Serranos often find new cracks in driveway slabs and separating retaining walls – a pattern tied to the area’s expansive clay and graded lots that local contractors know to check first. When we quote a Unilock job here, we look at where the water goes, what the subgrade actually is, and whether the existing drainage can handle the next wet season. Tell me what the house needs, not what you think it needs – then we’ll figure out the right fix.
Unilock Models & Products We Service in Los Serranos
We work with the Pomona Unilock service lines that make sense for Los Serranos’ housing stock and grade conditions. Brussels Block handles driveway and patio applications where the classic two-piece look fits the 1980s-2000s tract aesthetic. Brussels Dimensional gives a cleaner face for more contemporary custom homes. Beacon Hill is our go-to for retaining walls – the block’s size and structural capacity suit the hillside loads we see on Los Serranos lots. Lineo works well for modern paver patios and walkways. We source genuine Unilock pavers and wall units for repairs so color and dimensional match hold. For common repairs, we keep a working stock of Brussels Block and Beacon Hill units locally, which means faster turnaround for Los Serranos jobs without waiting on a freight order.

FAQs – Unilock Construction in Los Serranos
Expansive clay soils swell when saturated, pushing pavers out of plane and forcing joint sand out of the joints. On graded lots, water also moves downhill under the paver base, washing out fines and causing settlement. The fix is a properly prepared base with drainage, not just re-sanding. Call (866) 505-5254 for an exact assessment – estimates are free.
In most cases, yes. Los Serranos’ hillside grading ordinances require engineered drainage and slope stabilization for hardscape projects, and retaining walls over a certain height trigger plan review. We’ll confirm the permit path for your specific lot and handle the drawings and submittal. Call (866) 505-5254 and we’ll walk you through what applies to your property.
Sometimes, but we usually don’t recommend it on Los Serranos’ clay soils and graded pads. If the concrete slab is cracked from soil movement, the pavers will mirror those cracks. We assess the existing slab, the drainage, and the grade before advising overlay versus full removal. Call (866) 505-5254 for a free estimate either way.
Brussels Block handles steep Los Serranos driveways well when paired with a properly compacted base and edge restraint. For heavier slopes, we may recommend a more aggressive surface texture and additional drainage. We scope the product to the grade, not the other way around. Call (866) 505-5254 and we’ll evaluate your driveway in person.
We remove the affected section, excavate behind it, install proper drainage and engineered backfill, then rebuild with the same Unilock block line or a compatible unit. After a series of winter storms, a homeowner on a graded lot in the Los Serranos foothills called us about a separating retaining wall and cracked driveway. We rebuilt the wall with Unilock’s Beacon Hill blocks, added a French drain and compacted base, and replaced the driveway with Brussels Block pavers on a stabilized base – no more movement through the next rainy season. Call (866) 505-5254 for an exact quote – estimates are free.
