Unilock Construction in Montara, CA | Milpitas Construction
We provide independent Unilock paver installation, repair, and re-basing across Montara and the 94037 ZIP. We’re a full-scope general contractor, not a Unilock dealer or authorized affiliate, and the one thing that sets our Unilock work apart here is that we build every base, edge, and drainage detail around what Montara’s coastal terraces and county permitting actually demand. That means compacted subbase, pinned edge restraint, and drainage that holds through wet winters and salt wind. Call (877) 752-4194 for a free estimate.
Why Montara Residents Choose Us for Unilock Service
Unilock pavers earn their reputation when the base is right, and the base is where most coastal installations fail. We’ve laid Brussels Block, Beacon Hill, Elegance, and Town Hall lines on Montara driveways, patios, and hillside walkways long enough to know exactly how Pacific exposure punishes shortcut prep. Fog and salt air seep into every joint. Winter rain saturates thin base layers. When the subbase hasn’t been compacted to proper depth, the whole surface starts walking within two seasons.
Ken Stafford, who owns Milpitas Construction, spent two decades building and remodeling across the Bay Area before taking on coastal hardscape work in Montara. He grew up near the old Milpitas corridor when it was mostly warehouses and family shops, learned construction technology at Evergreen Valley College in San Jose, and picked up his finish standard from a carpenter father who wouldn’t stand behind anything he hadn’t done right. Build it right the first time – the Bay Area doesn’t give you a free pass on shortcuts. That’s how we approach every Unilock in Half Moon Bay and Montara install.

Common Unilock Construction Problems We Solve in Montara
- Joint sand washout and paver shifting on hillside terraces. Uphill runoff from neighboring lots concentrates during winter storms, scouring the bedding layer and leaving pavers loose. We re-excavate, add drainage, and re-set with Unilock polymeric sand so the joints survive the wet season.
- Efflorescence bloom and surface spalling from salt-laden fog. Onshore wind pushes salt moisture into lighter-colored pavers, especially when a sealer was skipped or applied over damp stone. We address the surface and recommend the right Unilock-compatible sealer applied at the correct moisture window.
- Edge restraint failure along driveway aprons and retaining walls. Rain-heavy winters push water under pavers even without freezing, and loose edges let the whole field migrate. We install pinned edge restraint that holds the perimeter where it belongs.
- Settling and lippage over old cottage fill. Many Montara homes sit on pier-and-post foundations or previously disturbed fill from decades of piecemeal additions. The original subbase was often never compacted to depth, so pavers tilting and heaving become visible fast. The fix is a real re-base, not a patch.
- Thin base over steep grade, with poor drainage. On hillside streets above Highway 1, a paver surface laid without proper drainage channels becomes a conduit for water heading downhill. We tie drainage to a county-compliant discharge point so the neighbor below stays dry.
Unilock Service in Montara: What Local Conditions Mean for Your Equipment
Montara is unincorporated San Mateo County, and that one fact changes everything about how a Unilock project gets built and permitted. There’s no city building department to fast-track a permit. Every driveway or patio on a bluff or terraced lot runs through county permitting and, on many parcels, coastal-zoning review under the Coastal Commission’s jurisdiction. The grading plan, drainage detail, and retaining-wall design get examined as closely as a house addition would. We’ve had Montara projects where the paver layout was approved only after we documented how the base would handle water from the uphill lot behind the property. On the hillside streets above Highway 1, neighbors’ downward-sloping runoff is a recurring point of friction – so county reviewers look hard at where the water goes. That’s why we install drainage channels, compact class-II base to depth, and set edge restraint as standard practice on Montara jobs, not as an upsell.
Unilock Models & Products We Service in Montara
We work with Unilock’s core paver lines most common on coastal Peninsula homes: Brussels Block for driveways and walkways where a classic cobble texture fits older cottage lots, Beacon Hill for larger flagstone-style patios, Elegance for a smoother, more contemporary finish, and Town Hall for a tumbled, timeworn look that suits mid-century ranch homes near the flats. When we repair or rebuild, we use Unilock’s own matching edge restraints, polymeric joint sand, and compatible sealer rather than generic substitutes – coastal wet-dry cycling punishes mismatched chemistry. We keep common polymeric sand and edge restraint on order for Unilock in Pacifica and Montara jobs so turnaround doesn’t drag when weather delays the next work window. We also stock compatible sealer options for salt-air exposure.

AfterUnilock Service Pricing in Montara
What you’ll pay depends on access, slope, drainage work, and whether we’re repairing a section or rebuilding the full base. Steep hillside lots in Montara typically add excavation and drainage scope that flat inland lots don’t carry. Here’s what we quote across the 94037 area:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Every estimate is free and written line-item, so you see the excavation, base, drainage, paver, and edge restraint costs separately. We don’t hand you a lump sum and hope you won’t ask what’s in it. Call (877) 752-4194 to schedule yours.

FAQs – Unilock Construction in Montara
Yes, in most Montara cases a paver driveway or patio triggers San Mateo County permitting, and on bluff or terraced lots coastal-zoning review may also apply. We prepare the grading, drainage, and base documentation the county wants to see, so the permit doesn’t stall mid-project. Call (877) 752-4194 and we’ll tell you what applies to your specific parcel.
Usually because the bedding layer wasn’t compacted to depth or the edge restraint gave way, letting surface runoff pipe through the joints. On Montara hillsides, uphill water concentrates and scours the sand out within a season or two. The fix is proper re-excavation, drainage, and fresh Unilock polymeric sand – not just sweeping more sand into the gaps.
Salt-laden fog and wind accelerate surface spalling and efflorescence on lighter pavers, especially if they were never sealed or were sealed while damp. We use Unilock-compatible sealers applied at the correct moisture level, which makes a real difference on coastal lots. Call (877) 752-4194 for an exact condition assessment and quote.
Yes, and we do it regularly. The difference is we engineer the drainage first. On one terraced lot above Highway 1, we tore out a heaved Brussels Block driveway where the old base had been laid thin over disturbed fill and uphill runoff was piping under the edge. We re-excavated to depth, added a drainage channel and compacted class-II base, re-set the Brussels Block with Unilock polymeric sand and pinned edge restraint, and tied the outlet to a county-compliant discharge point so the neighbor below stopped getting the water — the same standard we bring to Unilock in El Granada.
Rarely. Most older Montara cottage driveways sit on uncompacted fill or decomposed base material, and laying pavers over that just transfers the problem upward. We’ll tell you if the existing base can stay, but in our experience a proper re-base is the honest fix. Call (877) 752-4194 and we’ll inspect it for free before you spend anything.
