Unilock Construction in Hillsborough, CA | Gold Star Contractors
We provide independent Unilock paver, wall, and permeable system construction across Hillsborough, CA (94010) as a full-scope general contractor. What makes our Unilock work here different is simple: we read Hillsborough’s grading, drainage, and tree-protection requirements against Unilock’s own base and edge-restraint specs before any paver leaves the pallet. Call (833) 382-8544 for a free Unilock estimate in Hillsborough.
Why Hillsborough Residents Choose Us for Unilock Service
Hillsborough estate lots don’t forgive shortcuts. A paver driveway on a flat Corona lot and a paver driveway on a fog-washed Hillsborough hillside are two different jobs entirely. We’ve spent years working within Hillsborough’s planning expectations, where drainage plans and root-zone protection get the same plan-check scrutiny as the house itself. That means our Unilock installs start with the subgrade, not the surface. Noel Carranza, our owner and Hillsborough General Contractor, cut his teeth on multi-trade residential projects across California before building Gold Star Contractors, and he insists every crew read the grade and soil on the actual property before quoting a base depth. One call, done right – that’s the only way we know how to run a job. We’re an independent Unilock installer, not manufacturer-affiliated or authorized, which means we answer to you and to Hillsborough’s building standards, not to a dealer program. That independence lets us specify the right Unilock product for the actual conditions, not whatever a regional rep happens to be pushing that quarter.

Common Unilock Construction Problems We Solve in Hillsborough
- Base failure on sloped driveways and terraces. Hillsborough’s rolling estate terrain means a flat-lot base spec often fails within two wet seasons. Pavers settle and rock where the compacted aggregate wasn’t designed for grade and drainage, and that’s a call we get regularly from homeowners whose original install was spec’d as if the lot were level.
- Polymeric sand washout after heavy winter runoff. The Peninsula’s wet winters send a lot of water down Hillsborough driveways. When a driveway sheets water toward the street instead of to a designed drain, the joint sand erodes fast. We see this every March on properties that didn’t have a drainage line tied into the paver plan.
- U-Cara wall units shifting or bulging along sloped edges. Retaining walls on Hillsborough hillsides hold a lot of saturated soil during rainy months. When a U-Cara wall wasn’t engineered for hydrostatic pressure, the units shift or bulge outward. That’s a structural repair, not a cosmetic one.
- Edge restraint creep and paver spread at driveway aprons. Hillsborough’s long private driveways curve and slope, and when the edge restraint wasn’t pinned or the subgrade wasn’t stabilized, pavers spread at aprons and bends. The driveway looks fine for a year or two, then the edges wander.
- Root-zone conflict under mature oaks. Hillsborough’s oak canopy is part of the town’s character, but roots and paver bases don’t always agree. When a base is cut too close to a protected root zone without proper bridging or protection, the pavers heave within a season or two. We know how to design around those roots and keep the tree alive while the driveway stays flat.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough’s plan-check process puts tree-protection and grading plans on equal footing with the house itself. That’s not true everywhere on the Peninsula, but it is absolutely true here. On the oak-shaded sloped lots along the town’s edges, a paver terrace or driveway rebuild often needs root-zone protection and drainage detail approved before any Unilock base work can start. This changes the entire sequencing of a job. A contractor who’s only ever installed Unilock in Burlingame on flat, treeless lots will have their plans bounced back, or worse, they’ll start work and get a stop-work order mid-excavation. We bring the grading plan, the drainage design, and the tree-protection detail to the first plan-check review, because we’ve been through it enough times to know what Hillsborough’s reviewers will flag. It slows the front end of the project, but it means the Unilock work goes in once and stays put. On an oak-shaded sloped lot near the town’s western edge, we rebuilt a failing Brussels Block driveway that had been laid on a shallow base and was washing out each winter. We reset the subgrade to grade, added a pinned edge restraint and a designed drain line around the protected root zones, then re-laid the Brussels Block with fresh polymeric sand, and the driveway has handled two wet seasons without movement. That’s the kind of job Hillsborough demands, and it’s the kind we’re built for.
Unilock Models & Products We Service in Hillsborough
We install and service the Unilock lines most common on Hillsborough estates: Brussels Block for driveways and wide terraces, Beacon Hill smooth pavers for formal patios and pool surrounds, U-Cara wall systems for retaining walls and seat walls, and Eco-Priora permeable pavers where Hillsborough’s drainage requirements call for water to move through the surface rather than across it. On the parts side, we use genuine Unilock units and their matching edge restraint, polymeric sand, and U-Cara components. Substituting generic pavers or wall blocks undercuts the interlock and any warranty path. We keep the common components stocked locally and offer Unilock service in San Mateo, so Hillsborough projects don’t stall waiting on a shipment. When a terrace or driveway has good base and only cosmetic wear, we reset and re-sand rather than tear out. When the base or wall engineering is compromised, replacement is the honest call, and we’ll say so flat out.

FAQs – Unilock Construction in Hillsborough
Yes, but it takes more than a thick gravel base. We design the driveway to grade, pin the edge restraint, and tie a drainage line into the paver plan so the water that sheets down Hillsborough’s wet-weather slopes never pools against the base. Call (833) 382-8544 for a site assessment.
It can, especially on oak-shaded lots along the town’s edges. Hillsborough’s plan-check gives tree-protection and grading plans the same weight as the house, so if your patio or wall sits anywhere near a protected root zone, expect the town to require a protection plan before you break ground. We prepare that detail as part of our normal scope.
Brussels Block is a tumbled, textured paver that hides tire marks and daily wear on a working driveway. Beacon Hill is a smooth, dressier paver better suited to formal patios and pool surrounds. For Hillsborough driveways with real grade and winter runoff, we typically recommend Brussels Block for slip resistance and long-term appearance. Call (833) 382-8544 and we’ll talk through which one fits your specific driveway.
It’s almost always a drainage problem. On Hillsborough properties, patios that sheet water toward the house or the street instead of to a designed drain lose their polymeric sand within a season or two. We reset the joints and add a proper drainage path so the sand stays where it belongs. Call (833) 382-8544 for an exact diagnosis and quote.
Sometimes yes, if the wall units are intact but the base or drainage was undersized. If the wall is bulging from saturated soil and hydrostatic pressure, the engineering was likely wrong from the start, and rebuilding with proper drainage is the honest fix. We’ll tell you which situation you have, no sales pitch. Call (833) 382-8544 for a site walk.
