Unilock Construction in Hillsborough, CA | San Bruno Construction
We provide independent Unilock installation and repair across Hillsborough, from paver driveways that hold a steep grade to patios that respect the town’s tree and coverage rules. The one thing that makes our Unilock work here different is that we plan the base first: on Hillsborough’s hillside lots, the subgrade, not the paver, decides whether a job lasts. We serve every Hillsborough neighborhood in the 94010 ZIP from one local crew. Call (866) 472-1908 for a free estimate on your paver project.
Why Hillsborough Residents Choose Us for Unilock Service
We have laid Unilock pavers on dozens of Peninsula hillside lots, so we know how Brussels Block, Elegance, Beacon Hill, and Turfstone behave when they are holding a driveway apron on a 12 percent grade rather than sitting flat on a showroom display. That distinction matters more in Hillsborough than almost anywhere else on the Peninsula. The town’s estate lots roll and pitch constantly, and a paver system that fails on a slope does not just look bad; it channels winter sheet flow under the base and starts washing out in one season.
Noel Carvalho grew up off El Camino Real in San Bruno and trained at Skyline College before running residential projects across San Mateo County for over two decades. He has pulled enough permits at city offices and engineered enough hillside base courses to know when a paver job needs geogrid, not just more gravel. We bring that same eye to every Unilock installation and repair we take on, whether in Hillsborough or providing Unilock service in San Mateo. Good construction doesn’t announce itself; it just works, year after year.
We also coordinate the trades so you don’t have to. A paver driveway on an estate property often means a drainage contractor, a grading crew, and sometimes a tree arborist before the first unit goes down. We have the Unilock sales & service knowledge and the local subcontractor relationships to manage that whole sequence under one contract.

Common Unilock Construction Problems We Solve in Hillsborough
- Paver migration and joint-sand washout on steep driveway aprons. Brussels Block and Elegance units shift when winter sheet flow crosses the hardscape and the base was never built for slope drainage. We reset the units on new compacted base with geogrid and proper edge restraint tied into the slope drain.
- Efflorescence and surface staining on light-colored pavers under the oak canopy. Hillsborough’s mature oaks and redwoods drop tannin-rich drip that keeps paver surfaces damp and shaded. Elegance slabs in particular show white mineral bloom and dark organic staining. We clean and seal with breathable products, then adjust the surface pitch so water doesn’t linger.
- Edge restraint failure and settlement at the curb line. Driveways graded to shed rain toward the street put constant pressure on the apron’s outer edge. Once the restraint fails, field units spread at the curb and the whole section drifts. We rebuild that edge with proper depth and anchor it to the subgrade.
- Root heave under permeable Turfstone or grid installations. Mature redwood and oak roots push base course out of plane on Hillsborough lots. Turfstone sections lift and rock. We address the root-zone conflict first, then re-compact and re-level the grid.
- Base failure under patios on cut-and-fill lots. Hillsborough estate lots often sit on a mix of native soil and old fill. Where the two meet, paver patios settle unevenly. We dig out the transition, install a uniform engineered base, and reset the same units so the finish line stays true.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here is the thing about hardscaping in Hillsborough that no generic paver page tells you: the town’s building department reviews lot coverage and tree ordinances before demolition permits are issued. That means your paver driveway or patio plan has to fit inside coverage limits and stay out of protected oak and redwood root zones before a single unit goes down. We have seen projects where the ideal paver layout had to shrink by 400 square feet because the tree-protection radius overlapped the proposed edge line. On a steep lot, that reshapes the whole design, because you still need enough impervious or permeable surface to handle stormwater without undercutting the slope. This rule shapes Unilock work in Hillsborough more than any product catalog does. A paver patio on a flat Millbrae Unilock service lot has no such constraint. Here, every square foot of hardscape is a negotiation with the town’s arborist and planner, and we plan the base and drainage around what the permit actually allows.
Unilock Models & Products We Service in Hillsborough
We install and repair the full Unilock product range most common on Peninsula estate properties: Brussels Block for driveways and walkways, Elegance for a larger-format patio look, Beacon Hill for a tumbled, older-world finish, and Turfstone for permeable areas where the town wants water to infiltrate in place. We use genuine Unilock units and matching OEM edge restraints and joint sand. But on the base side, we use engineered aggregate and geogrid specific to each slope rather than a brand-generic spec, because on Hillsborough grades the base is what fails first. Where a section has heaved or washed out, we rebuild the base and reset the same units. Full replacement only makes sense when the restraint and subgrade are wrong top to bottom. We stock common Unilock units and OEM joint sand locally so a Hillsborough repair doesn’t have to wait on an out-of-state order.

AfterUnilock Service Pricing in Hillsborough
What a Hillsborough paver job costs depends on three things: slope, access, and tree-ordinance constraints. A flat patio on an easy lot is a different job from a driveway apron on a winding street with no staging area. Here are the ranges we quote from:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
These numbers cover typical Hillsborough estate conditions. A steep driveway with limited crane or pallet access will run toward the upper end. Call (866) 472-1908 and we’ll walk the site, check the slope and tree zones, and give you a written line-item quote; estimates are free.

FAQs – Unilock Construction in Hillsborough
Yes, when the base is built for the grade. Brussels Block and Elegance units hold a Hillsborough slope fine when they sit on compacted engineered base with geogrid and edge restraint tied into the slope’s drainage. Install them on a flat-lot spec base and they will migrate within two winters. Our base course is what makes the difference. Call (866) 472-1908 if your driveway is already moving and you want us to look at it.
It almost always does. The town reviews tree-protection and lot-coverage rules before issuing permits, so your paver footprint may have to shrink or shift to stay outside protected oak and redwood root zones. We plan the layout around those constraints from the first site visit, which saves you a redesign later. Call (866) 472-1908 before you finalize a paver plan.
Clean the surface with a paver-safe efflorescence remover, let it dry fully, then seal with a breathable paver sealer. But the real fix is adjusting surface pitch so water sheds instead of pooling under the oak drip line. We do both as part of a Hillsborough paver service call. Call (866) 472-1908 to schedule a look.
Usually we repair. If the units are intact and the failure is in the base, restraint, or drainage, we rebuild the section and reset the same pavers. Full replacement only makes sense when the subgrade is wrong from the bottom up. On a recent steep wooded driveway off a narrow winding Hillsborough street, we rebuilt a Brussels Block apron that had spread two winters running; we reset the same units on new base with geogrid and the finished apron now sheds winter rain to the street. Call (866) 472-1908 if you’re not sure which route your driveway needs.
It changes delivery planning. Many Hillsborough roads cannot take a full pallet drop, so we stage materials in smaller lifts and schedule deliveries in tight windows. That adds a little coordination time but keeps the road clear for your neighbors. We build that into the quote up front. Call (866) 472-1908 to talk through your site’s access.
