Unilock Construction in Hillsborough, CA | Daly City Construction
We install and repair Unilock paver driveways, patios, retaining walls, and steps throughout Hillsborough as an independent contractor, and we also provide Unilock in Burlingame. We’re not affiliated with Unilock, but we’ve spent years working with their Brussels Block, Beacon Hill Flagstone, Permeable, and Estate Wall systems on the exact type of sloped, design-reviewed properties this town is known for. The work here is different from flat-lot paving jobs – you’re dealing with tree protection, drainage plans, and grade changes that demand more than a catalog order and a compactor. Call (866) 505-5254 for a free estimate on your Hillsborough Unilock project.
Why Hillsborough Residents Choose Us for Unilock Service
Hillsborough isn’t a place where you can drop a pallet of pavers on the lawn and figure it out as you go. Nearly every lot is an acre or more, most are sloped, and the town’s Planning Commission reviews virtually every hardscape change as part of a larger remodel or addition. We know how to read those conditions before we quote, because the wrong base prep on a hillside driveway becomes a callback – and a puddle – within one wet season.
Noel Cabrera, our owner, grew up in the Westlake district of Daly City, where he learned early that fog-weathered homes and moisture management go hand in hand. That instinct carries straight into Unilock work: on shaded Hillsborough properties, moss and efflorescence on north-facing walls and walkways are predictable problems, not surprises. We plan for them. We also stock genuine Unilock units and compatible edge restraints, geogrid, and drainage components so we’re not substituting cheap lookalikes that compromise dimensional consistency. Unilock segmental systems only perform when the pieces match.

Common Unilock Construction Problems We Solve in Hillsborough
- Racking and bulging retaining walls on sloped parcels. When a segmental wall on a Hillsborough hillside wasn’t built with adequate drainage aggregate and geogrid, winter runoff saturates the backfill and pushes the wall out. We see this constantly on estate lots where the original install prioritized aesthetics over drainage engineering.
- Paver joints washing out on driveways that shed water toward the street. Hillsborough’s winter rain comes in sustained stretches, and driveways cut into hillsides channel serious sheet flow. Without proper slope and channel drains, the joint sand disappears within a season or two, leaving pavers loose and shifting.
- Efflorescence and moss staining on shaded patios. Fog-belt properties with north-facing patios keep joints damp through much of the year. Unilock’s textured finishes are beautiful, but they hold moisture on shaded surfaces, and that means white mineral deposits and green staining need regular attention.
- Base failure under paver aprons and driveway transitions. When a driveway is cut into a hillside and the subgrade wasn’t over-excavated and compacted properly, the apron settles and pavers crack or sink. This is a structural repair, not a cosmetic re-sand.
- Matching existing Unilock pavers for partial repairs. Older Hillsborough patios often need a section rebuilt after tree roots, drainage shifts, or simple age. We match the original Unilock line – Brussels Block and Beacon Hill Flagstone are common in estates built from the 1990s onward – so the repair blends instead of looking patched.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
Here’s what separates Unilock work in Hillsborough from any neighboring town: nearly every lot is an acre-plus estate parcel where paving and retaining walls are part of a design-reviewed remodel, not a standalone weekend project. On sloped properties, the town’s arborist and geotechnical input routinely precedes any excavation. That means Unilock wall and driveway work here is scoped against tree-protection zones and drainage plans, not just laid on a flat pad. We’ve worked on parcels where a mature oak’s root zone dictates where a retaining wall can sit, and where the geotech report changes the wall height or the required drainage layer depth. If your contractor skips that coordination, you’re not just violating a condition of approval – you’re building a wall that will move. We don’t skip it. We read the reports, talk to the town, and build the wall that actually holds.
Unilock Models & Products We Service in Hillsborough
We work with the Unilock lines most common on Hillsborough estates: Brussels Block, including the tumbled Brussels Dimensional, which shows up on driveways and garden paths; Beacon Hill Flagstone for patios and walkways; Permeable pavers for properties where runoff control is part of the project scope; and Estate Wall and other segmental retaining wall blocks for hillside terracing and driveway edges. On the parts side, we use genuine Unilock units and compatible accessories, because aftermarket substitutes may look close on a pallet but fail on tolerances. We keep a working inventory of edge restraints, geogrid, and drainage components here at our yard, which keeps Hillsborough turnaround faster than waiting on a distributor order.

FAQs – Unilock Construction in Hillsborough
Almost always, the original build skimped on drainage aggregate behind the wall or didn’t install geogrid to tie the block courses into the hillside. Hillsborough’s winter rains saturate the backfill, water pressure builds, and the wall starts to lean. We rebuild these properly: full excavation, drainage layer, geogrid, and matching Unilock units, just as we do for Unilock repair in Highlands-Baywood Park. Call (866) 505-5254 if you’re seeing movement.
They will if the base and drainage are engineered for the slope and the water volume. Joint sand alone won’t survive the wet season on a hillside driveway that channels runoff. We install proper slope, channel drains where needed, and compact the base in lifts. When the drainage is right, Unilock driveways hold up for decades.
Yes. On most Hillsborough parcels, hardscaping is bundled into the town’s design-review process, especially on sloped lots where drainage and tree protection are scrutinized. We coordinate with the arborist and geotechnical engineer when the project requires it, and we build to the approved plan. It adds time, but it prevents the expensive re-do.
Yes. We match by model line, size, and color, then order genuine Unilock units for the repair. Brussels Block and Beacon Hill Flagstone are the lines we see most often on Hillsborough estates, and we keep ordering channels open with Unilock distributors so the match is as close as the weathering on your existing pavers allows.
A paver driveway typically runs $7,000 to $18,000 here, and a paver patio $3,500 to $11,000, depending on slope, drainage, and access. Hillsborough hillside lots usually land toward the higher end because of excavation and retaining considerations. Call (866) 505-5254 and we’ll give you a written number after walking the site.
