Unilock Construction in Los Serranos, CA | Stallion Contractors
We’re Stallion Contractors, and we install, repair, and rebuild Unilock paver systems across Los Serranos. We are an independent Unilock service provider, not a factory-authorized dealer. The single thing that makes our Unilock work different in Los Serranos is that we plan every paver project around the County’s hillside and fire-zone requirements before we ever touch a shovel. Call (855) 600-3192 for a free estimate on paver driveways, patios, and retaining walls.
Why Los Serranos Residents Choose Us for Unilock Service
Most contractors in this area can lay pavers. Few can tell you why a Cambridge Cobble driveway failed on a graded equestrian lot, or what to do when your U-Cara wall starts leaning after two fire seasons. Ruben Montoya, who leads our team, grew up in Colton and studied construction at San Bernardino Valley College, where he was on job sites before he ever handed out a business card. Over two-plus decades in the Inland Empire, he’s built a reputation for structural honesty, including Unilock service in Chino and surrounding communities. We read Unilock’s own technical literature, base prep specs, edge restraint details, and polymeric joint sand requirements, not a dealer binder. That means our recommendations in Los Serranos come from tear-outs and rebuilds on actual Unilock pavers, not from a showroom display.

Common Unilock Construction Problems We Solve in Los Serranos
- Joint sand washing out on Brussels Block driveways. Santa Ana wind events and flash storms hit Los Serranos hard. When sanded joints get scoured, Brussels Block units shift and open gaps at the driveway apron. We re-sweep with Unilock’s specified polymeric sand after repairing the edge restraint, because new sand alone won’t hold if the border is gone.
- Efflorescence blooming on Cambridge Cobble. This chalky white haze means moisture is wicking up through the concrete sand bedding. In Los Serranos, we see it most on patio installations where the base wasn’t drained properly. The fix is correcting the drainage path, not scrubbing the surface.
- Edge restraint failure on sloped driveways. Los Serranos hillside driveways, especially those on graded parcels, put real pressure on edge restraints. When the base was compacted in lifts too thick for the equipment, the pavers toe-out at the grade break. We cut back, re-compact in proper lifts, and reinstall with Unilock edge restraint that actually anchors the border.
- U-Cara retaining wall lean and step-out. Built without geogrid and drainage aggregate, U-Cara walls in Los Serranos shift with heat and frost cycling. We see top-course step-out on canyon-edge properties within two or three seasons. Repair means partial disassembly, installing the missing drainage and geogrid, and rebuilding the face to spec.
- Base failure under older paver installations. A lot of Los Serranos homes date to the mid-century ranch era, and some patios were laid directly on native soil. The pavers look fine until they don’t. We pull the units, re-grade, and install a proper compacted aggregate base. New sand over a failed foundation just buys a season.
Unilock Service in Los Serranos: What Local Conditions Mean for Your Equipment
Los Serranos is unincorporated San Bernardino County, which changes the math on any hardscape project. Parcels that touch a hillside or fire hazard zone routinely need grading and fire-clearance plans at the first County counter visit. So paver work here is often scoped alongside slope stabilization and defensible-space clearing, not as a standalone flatwork swap. On a graded equestrian-lot parcel off the hillside stretches, we rebuilt a failing Cambridge Cobble driveway that had been laid directly on native soil. The Santa Ana winds had scoured the joints and the apron had toe-out at the grade break. We pulled the units, re-graded to the County-approved slope, reinstalled on a compacted aggregate base with proper edge restraint and Unilock polymeric sand, and the driveway now drains away from the garage instead of into it. A standard over-the-counter permit can stall when the parcel touches a hillside or fire hazard zone. The workaround is bringing grading and fire-clearance plans to the first counter visit. We do that.
Unilock Models & Products We Service in Los Serranos
We work with the full Unilock lineup that makes sense for Southern California hillside properties. That includes Brussels Block, the tumbled dimensional paver you see on a lot of Los Serranos driveways and walkways. We also handle Cambridge Cobble and Cambridge Pavingstones with ArmorTec, Beacon Hill smooth and non-tumbled pavers, and the U-Cara multi-face retaining wall system. When we repair, we use Unilock’s own matching units, edge restraint, and specified polymeric sand so the joint profile and color hold. We’ll patch a sound bed with matching pavers before we’ll recommend a full rebuild, whether it’s here or for Unilock repair in Montclair. But when the base or drainage is the real failure, the honest answer is tear-out and re-base. Good work doesn’t need a sales pitch, it needs the right materials and someone who knows what they’re doing.

FAQs – Unilock Construction in Los Serranos
Often, yes. Because Los Serranos is unincorporated San Bernardino County, any paver work on a parcel that touches a hillside or fire hazard zone can trigger grading and fire-clearance reviews. A flat patio replacement on a level lot may go through over-the-counter, but a driveway or retaining wall on a sloped parcel usually needs plans first. We handle that coordination. Call (855) 600-3192 and we’ll tell you what your specific parcel needs before you spend a dollar on materials.
Santa Ana winds and flash storms in Los Serranos scour sanded joints, and once the sand goes, the Brussels Block units start shifting and opening gaps. The annual cycle usually means the edge restraint has failed or the sand was never compacted properly. We re-sweep with Unilock’s specified polymeric sand only after repairing the border and confirming the base is sound. Call (855) 600-3192 for an inspection and an exact repair quote.
Yes. We stock and order from Unilock’s current product line, including Brussels Block, Cambridge Cobble, and Beacon Hill pavers. We match the unit profile first, then the color family, using Unilock’s own matching units so the repaired area doesn’t look like a patch. If your existing install is an older or discontinued color, we’ll tell you that honestly before we start.
It typically will. Concrete and asphalt crack under the repeated heat cycling we get here, and asphalt can soften in extreme heat. Unilock pavers are individual units with sanded joints, so they flex with soil movement instead of cracking. They also have no combustible surface for embers to ignite. The key is a properly compacted base and edge restraint, because those are what actually hold up on hillside parcels. Call (855) 600-3192 to talk through your specific driveway.
Sometimes. If your parcel doesn’t trigger a fire-zone or hillside review, a patio addition may not require a re-grade. Retaining walls are different, because any wall over a certain height or on a slope needs County review and likely a grading plan. We evaluate the site, tell you what’s actually required, and then scope the project so it passes the first time. Call (855) 600-3192 for a site assessment and a straight answer.
