Unilock Construction in Hillsborough, CA | Workshop Contractors
As a Hillsborough General Contractor, we install, repair, and rebuild Unilock paver driveways, patios, and walkways across the area, and we do it with the town’s design-review and tree-protection rules baked into every base we dig. Unilock makes a tough paver, but on Hillsborough’s sloped, wooded lots, the difference between a driveway that holds for twenty years and one that shifts in three comes down to what’s underneath it. We’re independent Unilock installers, not a manufacturer affiliate, and we handle everything from new Brussels Block driveways to surgical repairs on settled Umbriano patios. Call (844) 384-3361 to schedule a free estimate.
Why Hillsborough Residents Choose Us for Unilock Service
Noel Figueroa, our owner, learned early that a paver is only as good as the base it sits on. He grew up around tradesmen who framed houses by hand, studied construction at Chaffey College, and has spent the years since learning what happens when water, roots, and slope meet a hardscape installation that wasn’t engineered for all three. In Hillsborough, that lesson shows up on nearly every job.
We lay Unilock pavers with the local rules in mind. We know what Hillsborough’s design review board asks for, we know how a heritage oak changes a driveway alignment, and we know that a base compacted in lifts with proper drainage costs less over time than a patio that gets pulled out and rebuilt. We use OEM Unilock pavers and matching restraint systems on repairs so color and profile stay consistent, and we’re honest when a failing base means the section needs to be rebuilt rather than patched. One contractor, every trade. From the paver surface down to the compacted sub-base, we handle it.

Common Unilock Construction Problems We Solve in Hillsborough
Hillsborough’s lots create a specific set of failures. Here’s what we see most often:
- Efflorescence on Brussels Block after wet winters. The Peninsula’s winter rains pull salts up through concrete pavers, leaving white mineral blooms on the surface. It’s cosmetic, not structural, but it looks wrong. We clean it correctly and, more importantly, fix the drainage that feeds it.
- Base settlement on sloped driveways. When a sub-base isn’t compacted in six-inch lifts with proper slope, winter runoff from Hillsborough’s wooded hillsides finds its way under the pavers. The base erodes, the pavers sink, and you get a rippled driveway. We rebuild the section with positive drainage away from the house.
- Edge restraint failure from roots and mud. Umbriano and Beacon Hill installations on tree-heavy lots take pressure at the perimeter from oak roots and saturated winter soil. Loose edges let sand escape and pavers drift. We reset restraint systems properly and re-sand joints with polymeric sand that holds.
- Joint sand washout and organic staining. Shaded patios under oaks and redwoods never dry out. Leaves and needles stain the surface, and winter rain flushes joint sand downhill. It’s a Hillsborough signature problem, and it needs a maintenance plan tied to the lot’s shade and drainage, not a generic sealer.
- Tree-root conflict with paver layouts. A protected oak doesn’t get cut for a driveway. The hardscape gets rerouted or raised. We build root-safe bases with geotextile separation and deeper aggregate where needed, which keeps roots alive and pavers stable.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here’s the thing about Hillsborough that no generic paver page tells you: the town’s design-review process often requires exterior hardscape finishes, including paver color and pattern, to be approved before demolition starts. That means your paver selection isn’t the first decision. It’s the fourth or fifth, after the arborist report, the site plan, and the design-review submittal. A single protected heritage oak can force a driveway or patio to be re-routed or built on a raised, root-safe base, and those decisions change the layout and base engineering before any Unilock product gets ordered. Up on Black Mountain Road, we worked on a Brussels Block driveway where winter runoff from the hillside had settled the field. We pulled the affected pavers, re-compacted the base in lifts with positive slope away from the garage, reset everything on a fresh bedding course, and re-sanded the joints. We coordinated the whole thing around a protected oak so no root zone was disturbed. That’s not a spec-sheet installation. That’s Hillsborough.
Unilock Models & Products We Service in Hillsborough
We install and repair the full Unilock residential line, including Brussels Block, Umbriano, Beacon Hill, and the Elegance series. Brussels Block and Umbriano are the two we see most on Hillsborough driveways and patios; Beacon Hill shows up on walkways and accents, and Elegance on higher-end custom projects. On repairs, we use Unilock’s own matching pavers so replacement stones don’t stand out against the original field. We also stock matching restraint systems and polymeric joint sand locally for faster turnaround on Hillsborough jobs. When a paver is discontinued or a color lot has shifted over years, we blend from multiple pallets and work with what the original installation gave us.

AfterUnilock Service Pricing in Hillsborough
What you’ll pay depends on the size of the project, the paver line, and whether we’re repairing or rebuilding a base. Here’s what Hillsborough homeowners can expect:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Those numbers shift with site conditions. A flat lot with clean access costs less than a hillside patio that needs a raised base and root-barrier work. What doesn’t change is the way we quote: a free estimate with written line items, so you see exactly what the base, bedding, pavers, and labor cost. Call (844) 384-3361 for an exact quote on your Hillsborough project.

FAQs – Unilock Construction in Hillsborough
Yes, when the base is built for it. Settlement happens when a sub-base isn’t compacted in lifts or drainage isn’t pitched away from the house. On Hillsborough’s hillside lots, we compact in six-inch layers, add positive slope, and use geotextile separation where roots are present. Build it right the first time. The second time costs twice as much and nobody’s happy about it. Call (844) 384-3361 to have us look at your site.
Often yes. Hillsborough’s design-review process can require exterior finish approvals, including paver color and pattern, before demolition begins. That approval sequence affects ordering and site prep, so we plan the submittal early. We’ve done enough Hillsborough work to know what the board tends to flag and what sails through.
Efflorescence is mineral salts migrating through concrete pavers during wet winters. It’s common on Brussels Block and other Unilock concrete lines after a rainy Peninsula winter, and we handle Unilock in Burlingame too. It’s not a product defect. We clean it with the right process and, just as importantly, check that your base drainage isn’t making it worse. For a cost estimate, call (844) 384-3361.
You can, if the base under the settled section is still sound. We pull the affected field, re-compact the base, reset the pavers, and re-sand the joints. If the base has failed over a larger area, patching becomes a temporary fix and we’ll tell you that. We’d rather rebuild a section once than redo it twice.
A protected oak or redwood can dictate the patio’s footprint, and that’s before any Unilock product is ordered. The layout may need to be re-routed around a root zone or built on a raised, root-safe base with deeper aggregate. We plan the hardscape around the tree, not the other way around. Call (844) 384-3361 and we’ll walk the site with you.
