Unilock Construction in Hillsborough, CA | Millwright Builders
We provide independent Unilock construction service across Hillsborough, from paver driveway installations to patio builds and full driveway replacements. We also offer Unilock in Burlingame and nearby Peninsula communities. What makes our Unilock work different here is simple: we’ve spent years watching how these pavers behave against Hillsborough’s expansive clay soils, hillside grades, and winter runoff, and we build accordingly. If you’re planning Unilock hardscape on a Hillsborough estate, call (866) 925-0334 for a free estimate.
Millwright Builders is an independent contractor. We are not manufacturer-affiliated or authorized by Unilock. We specify their pavers because we know how they perform, not because anyone certified us.
Why Hillsborough Residents Choose Us for Unilock Service
Most contractors can lay pavers. Few can tell you why a Brussels Block driveway heaved at the third joint from the curb, or whether your Richcliff patio needs re-sanding or a corrected base. That distinction matters in Hillsborough, where a failed paver field isn’t a cosmetic issue, it’s a drainage problem waiting to reach your foundation.
Noel Castañeda, our owner, spent the better part of two decades doing residential and light commercial work across the Peninsula, including Millbrae Unilock service, before founding Millwright Builders. He grew up watching the industrial corridor along the bay, where good structures don’t happen by accident. That’s the lens we bring to every Unilock job in Hillsborough: read the site, understand the water, then build.
We also offer true general contractor scope. Your Unilock driveway doesn’t exist in isolation, it meets your foundation, your drainage, your fencing, and your roofline. We can address all of it under one accountable contract. From the roofline to the back patio, one contractor, one conversation.

Common Unilock Construction Problems We Solve in Hillsborough
- Efflorescence on Brussels Block and smooth-faced pavers. Hillsborough’s clay holds moisture against the paver base through winter. When that moisture wicks up through the pavers and evaporates, it leaves white mineral deposits on the face. We address it by correcting base drainage, not just pressure washing the surface and hoping it doesn’t return.
- Joint sand washout on steep driveway aprons. Hillsborough driveways frequently climb from narrow roads up to hillside homes. Runoff concentrates instead of sheet-flowing, and generic joint sand disappears in one wet season. We use stabilized polymeric sand rated for slope applications.
- Edge restraint failure and paver migration. Tree roots along Hillsborough’s canopied roads lift base material and displace edge restraints. The result is lip, step-off, and a paver field that creeps toward the street. We reset restraints on compacted base and re-establish positive fall.
- Surface spalling on older Umbriano and Richcliff installs. Hillsborough’s shaded lots keep pavers saturated longer, and when freeze-thaw cycles hit, the face of older pavers can spall. We assess whether the pavers are salvageable or need sectional replacement.
- Heaved sections from expansive clay movement. Hillsborough’s clay soils expand and contract with seasonal moisture. A paver field laid on an uncompacted or poorly drained base will heave within a few seasons. We correct the subgrade, not just the surface.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
On Hillsborough’s narrow, tree-canopied roads, a paver driveway delivery fills the street edge, so we phase pallet drops and truck staging around the town’s traffic-control requirements rather than dumping the whole job’s material at once. That’s not how we’d handle a job in a wide suburban cul-de-sac. It’s a Hillsborough-specific reality that affects scheduling, delivery costs, and how long your driveway project takes from start to finish.
The same narrow roads that complicate staging also tell us something about your drainage. Hillsborough’s lots are large, but the paved area between house and street is often constrained by mature trees and steep grades. Water has fewer places to go. That’s why we treat every Unilock paver field as part of a drainage system, not a decorative surface. Build it right the first time, the Peninsula weather will find out if you didn’t.
Unilock Models & Products We Service in Hillsborough
We work with the Unilock lines most common on Hillsborough estates: Brussels Block for driveways and approach aprons, Beacon Hill for a more formal flagstone look, Richcliff for patios where a larger-format paver reads better against a large home, and Umbriano for a smooth, contemporary finish.
We match Unilock pavers and their proprietary edge restraints by line and color so repairs and additions blend with existing field. We stock common Brussels Block and Richcliff colors locally for faster Hillsborough turnaround on repair jobs. Special-order colors and larger-format lines take longer, and we’ll tell you that up front. We use stabilized polymeric joint sand and geotextile or grid base on clay rather than generic sand alone.

What drives the cost on a Hillsborough paver job is base work. If the subgrade is sound and we’re installing new pavers, the job is straightforward. If we’re replacing a failed driveway on expansive clay, expect geogrid, additional excavation, and drainage correction. Those line items don’t exist on a flat-lot quote.
Our free estimates are written and line-itemed. You’ll see exactly what the base, drainage, pavers, and labor cost. No change orders when the site surprises us, because we read the site before we quote. Call (866) 925-0334 for your estimate.

FAQs – Unilock Construction in Hillsborough
Joints fail first because they’re the drainage system’s weak point. Hillsborough’s expansive clay moves with moisture, and when the base shifts even slightly, the pavers hold while the joint sand migrates or washes out. We stabilize joints with polymeric sand and address base drainage so the movement stops at the source. Call (866) 925-0334 for a joint-failure assessment on your paver driveway.
Yes. We match by line, color, and wear so the addition blends with the existing field. Matching is one reason homeowners call us for additions rather than starting over. Pavers that have been down for a decade have a different face than new stock, and we’ll tell you honestly whether a seamless match is achievable or whether a deliberate transition line will look better. Call (866) 925-0334 to discuss your project.
They affect staging, delivery, and sequencing. We phase material drops so pallets don’t sit in the street edge and block neighbors or fire access. Hillsborough’s traffic-control requirements mean we coordinate deliveries in advance and schedule work in phases. It adds some scheduling time but keeps the job legal and the road passable. Call (866) 925-0334 and we’ll walk through how it applies to your specific street.
Hillsborough’s Planning Department applies design review to most exterior work, and a paver driveway replacement is no exception, especially on a large-lot estate with existing hardscape. We’ll help you understand what the town will want to see and prepare the submittal package as part of our scope. We’ve worked through the process on multiple Hillsborough properties and can tell you what tends to draw comments and what passes cleanly. Call (866) 925-0334 to discuss your driveway’s review path.
It depends on what failed. If the pavers are structurally sound but the joints washed out and a section heaved, repair and re-sanding is cheaper than full replacement, we’ve done it on tight Hillsborough driveways where the pavers were reused, not replaced. If the subgrade is heaved across a large field, re-laying on a corrected base is cheaper than chasing joint failures season after season. Call (866) 925-0334 and we’ll give you an honest read on which path makes sense for your driveway.
