Unilock Construction in Redwood Shores, CA | Millwright Builders
We provide independent Unilock paver and wall installation and repair across Redwood Shores, CA. The thing that makes our Unilock work different here is simple: we build for bay mud. Nearly every paver driveway, patio, or retaining wall in this community sits on engineered fill and dredged sediment, and if the base isn’t designed for that reality, the prettiest Unilock product will heave, rock, and open joints within a few seasons. Call (866) 925-0334 for a free estimate on any Unilock construction project in Redwood Shores.
We’re a Redwood Shores General Contractor, not a paver-only shop, which means we understand how your Unilock hardscape ties into the rest of the property: the drainage, the foundation, the roofline. Noel Castañeda, who leads Millwright Builders, spent two decades doing residential and light commercial work across the Peninsula before we ever laid our first Unilock unit here, and that structural background shapes how we approach every base, every joint, every fall line.
Why Redwood Shores Residents Choose Us for Unilock Service
We’ve installed and repaired Unilock in San Mateo and across the Peninsula for years, so we know how their profile geometry, jointing, and base requirements behave under real bay-front conditions, not just in a showroom. As an independent installer, we specify and build to the site, not to a dealer’s sales sheet. That distinction matters in Redwood Shores, where the ground itself pushes back.
We’re also licensed as a general contractor, which means one contract covers the hardscape, the drainage corrections, and any adjacent structural work. You don’t get handed off to a sub who’s never seen the soil report. You get one accountable builder. We use genuine Unilock units and matching accessories for repairs so color, texture, and profile stay consistent with your existing field. And when a base has failed, we tell you honestly whether resetting is the durable fix or whether spot patching will buy you a few seasons.

Common Unilock Construction Problems We Solve in Redwood Shores
- Heaving and rocking pavers from bay mud settlement. Redwood Shores sits on engineered fill and dredged bay mud, and we regularly see paver fields that have heaved into ridges or dropped into low spots within a decade of installation. The cause is almost always an under-engineered sub-base.
- Polymeric sand washout at lagoon-front and slough-front properties. When drainage falls toward the Redwood Shores Lagoon or the slough rather than away from the house, joint sand erodes fast. We rebuild with proper fall and a base that holds its grade, then re-sand with quality polymeric joint material.
- Efflorescence and salt-air staining on lighter Unilock pavers. The morning fog and damp air off the bay accelerate white mineral deposits on Brussels Block and Beacon Hill units. We clean and restore, but more importantly, we address the moisture path that causes it to return.
- Cracked driveway and apron units where the slab underneath has settled. This is especially common on 1980s and 1990s tract homes in Redwood Shores where the original concrete aprons have shifted. We remove the affected field, correct the base, and reset the Unilock units to match.
- Wall connector corrosion and staining at hidden fasteners. Unilock wall systems with concealed connectors take a beating in this damp microclimate. We replace corroded hardware and rebuild failing sections before the wall moves out of plumb.
Build it right the first time, the Peninsula weather will find out if you didn’t. That’s not a slogan; it’s what the fog and the bay mud do to shortcuts.
Unilock Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Redwood Shores is a master-planned community built on engineered fill and dredged bay mud, so nearly every construction project, from room additions to full rebuilds, must account for bay mud settlement and high water tables. Often that means deep piles or moisture barriers that contractors in neighboring cities like Unilock in Belmont or San Carlos rarely encounter. What that means for Unilock owners specifically: a paver patio or driveway here lives or dies on the sub-base and drainage design. The local building department already requires soil reports and engineered foundations for any new structure because of the bay mud, and that same expectation carries over to how we build hardscape bases. A patio that would hold fine on the stable soils of San Carlos will sink, crack, and open its joints within five to seven years on Redwood Shores fill if the base is just compacted road base over loose sediment. We excavate deeper, install geotextile where the soil is soft, and compact engineered aggregate in lifts so the Unilock surface stays level for decades, not seasons. The lagoon and slough drainage also plays in: fall lines that push water toward the house or toward the water will erode joints and saturate the sub-base, so we design drainage before we lay the first paver.
Unilock Models & Products We Service in Redwood Shores
We work with the full Unilock residential range: Brussels Block for tumbled, dimensional paver driveways and paths; Beacon Hill for flagstone-style patios; the Brussels Dimensional System and Uni-Decor for walls and steps; and Stoneyhurst and Richcliff for wall and patio lines that need a more formal profile. We use genuine Unilock units and matching accessories for repairs so color, texture, and profile stay consistent with the existing field, and we source quality base aggregate, geotextile, and polymeric joint sand rather than cheap substitutes. When settlement has compromised the sub-base, we tell owners honestly that resetting on a proper engineered base is the durable fix and spot patching is only a stopgap.

We recently worked on a lagoon-side lot off Unilock in Foster City near Redwood Shores Parkway where a Brussels Block driveway had heaved into a ridge and the polymeric joints had washed out toward the water. Our crew excavated the failed base, recompacted engineered aggregate with proper fall away from the garage, then reset and re-sanded the original units to match the house’s 1990s Mediterranean stucco and tile roof. The homeowner got a level, draining apron back without replacing the whole field. That’s the repair-before-replace approach that saves real money here.

FAQs – Unilock Construction in Redwood Shores
No. We’re an independent installer and general contractor. We’re not manufacturer-affiliated or dealer-bound, which means we specify and build to the site conditions in Redwood Shores rather than to a manufacturer’s sales sheet. If a different paver or base system would perform better on your lot, we’ll tell you.
Yes. We source genuine Unilock units and matching accessories so repairs blend with the existing field in color, texture, and profile. We also use quality engineered base aggregate, geotextile, and polymeric joint sand rather than cheap substitutes that erode quickly in this damp climate. Call (866) 925-0334 to discuss your repair.
The real fix is drainage, not more sand. If your fall line pushes water toward the lagoon or slough, the joints will keep eroding no matter what product you use. We correct the grade, rebuild the base, and re-sand with quality polymeric sand so the water moves away from the structure and the joints stay put. We’ll assess yours for free, call (866) 925-0334.
Most paver driveway replacements take three to five working days once we have the materials staged. Patios and smaller repairs are typically faster. The excavation and base work on Redwood Shores fill can add time because we compact in lifts and sometimes need geotextile, but cutting corners on that part is exactly what causes early failure.
Paver driveway installation here typically runs $7,000 to $18,000, and paver patios run $3,500 to $11,000. The Redwood Shores premium comes from deeper excavation, more aggregate, and more drainage work than you’d need on stable soil in San Carlos or South San Francisco. For an exact number, call (866) 925-0334 and we’ll come out for a free estimate.
