Unilock Construction in Redwood City, CA | San Bruno Construction
We’re a Redwood City General Contractor that installs and services Unilock paver systems throughout Redwood City, CA – and the one thing that separates our work here is knowing how Chapter 7A wildfire code in the 94062 hills and engineered fill in Redwood Shores change which Unilock products actually hold up. That split between flatland tracts and hillside WUI zones means the same paver spec that’s perfect in downtown won’t pass inspection three miles west, and most contractors don’t catch that until the plans get kicked back. If you’re considering a Unilock driveway, patio, or retaining wall anywhere in Redwood City, call (866) 472-1908 for a free estimate from a crew that’s already done this work across every ZIP in town.
Why Redwood City Residents Choose Us for Unilock Service
We’ve installed Unilock pavers and walls across San Mateo County, including Woodside Unilock service, long enough to treat their product lines like a familiar toolset. Brussels Block for a courtyard patio, Beacon Hill for something with cleaner geometry, Richcliff when the homeowner wants a more contemporary face, the U-Cara wall system for seat walls and freestanding features. The products are solid – but Redwood City’s specific soil, grades, and marine-layer moisture patterns are what determine whether that product survives eight wet winters or starts heaving by year three. Noel Carvalho, who owns San Bruno Construction, grew up just over the hill and spent two-plus decades running residential jobs across San Mateo County, so he reads Redwood City plans the way a local should – checking drainage first, subgrade second, and paver selection third. Good construction doesn’t announce itself – it just works, year after year.
We’re not an authorized Unilock dealer and we’re not affiliated with the manufacturer. What we bring is field experience with their product lines in this exact climate, plus access to a full range of complementary materials through our broader general contracting work – roof drainage, exterior cladding, and the structural pieces that determine whether a paver installation stays flat. When you source Unilock materials for sales & service, you want a contractor who’s seen how those pavers behave on a fog-dampened Redwood City patio in February. That’s us.

Common Unilock Construction Problems We Solve in Redwood City
Here’s what we see most often when we’re called out for Unilock repairs in Redwood City – and most of these trace back to one of two things: this city’s moisture cycle or its dramatic grade changes between flatland and hillside.
- Efflorescence bloom on north-facing patios. The marine layer that rolls through the flatlands around 94061 and 94063 pushes moisture through the paver body in cycles, and on patios that never get direct sun, you’ll see white chalky deposits rise to the surface. It’s cosmetic but persistent. We address it with proper capillary breaks and paver sealing targeted to the specific exposure.
- Polymeric sand loss on steep Emerald Hills driveways. Atmospheric-river storms hit the 94062 grades hard, and standard polymeric sand washes out of joints on anything steeper than about 5%. We re-sand with a formulation that’s rated for sloped applications and, where Chapter 7A applies, switch to an ember-resistant sand that satisfies the fire code.
- Base settlement in Redwood Shores. The engineered fill under 94065 needs deeper excavation and mechanical compaction before you lay a single Unilock unit. When the subgrade’s shorted, you get paver lippage and water ponding within the first rainy season. We over-excavate to spec and test compaction before the base goes in.
- Frost heave at unrestrained edges. On hillside decks and walkways in the 94062 hills, pavers without proper edge restraint drift outward over winter, leaving gaps and spalling edges. Unilock’s own edge restraints solve this, but the detail has to be specified from the start – particularly where WUI-compliant assemblies are required.
- Drainage failures that undermine pavers over time. Redwood City’s flat/low-slope lots see water ponding during heavy storms, and if the pitch isn’t regraded before the paver base goes in, you’ll chase the same puddles forever. We fix the grade first, then the surface.
Unilock Service in Redwood City: What Local Conditions Mean for Your Equipment
Here’s the reality most homeowners don’t hear until their plans get rejected: Redwood City’s building department serves two completely different construction worlds. Downtown high-rises built on podium decks file permit sets alongside hillside rebuilds in the Wildland-Urban Interface, and the reviewer doesn’t care that your paver patio seems simple. In the 94062 hills around Emerald Hills and Edgewood Park, any Unilock installation tied to a deck, walkway, or setback must be detailed with noncombustible edge restraints and ember-resistant joint sand to pass Chapter 7A review. That exact same spec in the flatland tracts of 94061 – where the housing stock is mostly 1950s and 60s ranchers and Eichler-style homes on slab foundations – would be overkill and, in some cases, rejected outright for reasons unrelated to fire risk. This one code boundary is what separates a clean permit from a two-month stall, and it’s a distinction most paver installers who quote Redwood City jobs from a generic San Mateo County playbook never anticipate. We detail around it from the first site visit.
Unilock Models & Products We Service in Redwood City
We work with all of Unilock’s core residential lines: Brussels Block for traditional driveways and patios, Beacon Hill for larger-format modern layouts, Richcliff for a more architectural face, and the U-Cara Wall System when a project calls for a seat wall, a retaining wall, or a built-in planter. Our stance on parts is specific – we use Unilock’s own edge restraints, polymeric sands, and wall components on Unilock jobs because those systems are designed to work together and stand up to the Peninsula’s wet-dry cycling. For base materials, we source quality aggregate to local spec from suppliers who service Redwood City contractors. And we’ll tell you honestly when a repair – re-sanding and re-setting a handful of units – will outperform a full replacement, and when the base has degraded enough that patching is just throwing money at a losing cause.

AfterUnilock Service Pricing in Redwood City
Paver work in Redwood City is priced by square footage, site access, and how much subgrade correction the site demands. A flat 94061 backyard patio runs on the lower end because the soil’s predictable; a steep 94062 driveway where trucks have to stage carefully and drainage has to be regraded lands on the higher end. Here’s what we’re seeing for Unilock work across Redwood City right now:
| Service | Typical Redwood City Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
Every estimate includes a site walk, subgrade evaluation where it matters, and a written line-item breakdown. No percentage games, no vague “materials and labor” bottom line. Call (866) 472-1908 to schedule your free estimate, and we’ll give you a number that holds unless the ground itself surprises us.

FAQs – Unilock Construction in Redwood City
If the patio is within the defensible-space zone of a hillside home, yes. The 94062 hills fall under Wildland-Urban Interface fire code, and the building department will require noncombustible edge restraints and ember-resistant joint sand – a detail that never comes up on flatland jobs in 94061 or 94063. Call (866) 472-1908 and we can confirm whether your specific lot falls inside or outside the Chapter 7A boundary before you spend anything.
Engineered fill means the ground under your home was placed and compacted as part of development, but the upper layers often aren’t compacted to a spec that’ll support pavers long-term. We over-excavate, add a proper aggregate base, and compact in lifts – something that’s absolutely necessary in 94065 but often skipped by installers who price it like a flatland job. For an exact assessment, call (866) 472-1908 – the estimate’s free.
Yes, but installation details decide whether they’ll show efflorescence or hold their color. North-facing patios in the flatlands cycle through dampness almost daily, and without proper base drainage and a capillary break, minerals migrate upward through the paver body. We design bases with that moisture cycle in mind, and we’ll tell you what to expect for your specific exposure.
For most flatland driveways, you’re looking at two to four weeks from submittal to approval, assuming the drainage plan is clean. Hillside jobs in 94062 add time when Chapter 7A review is triggered – sometimes as much as a month – because the fire-code details have to be verified by the reviewer. We handle the permit set and any resubmittal so you’re not the one at the counter. Call (866) 472-1908 for a timeline specific to your address.
We do. The U-Cara Wall System works well as a low retaining wall or seat wall alongside a steep driveway, but the foundation below it matters more than the block above it. On steep Emerald Hills lots, that means proper setback, drainage, and sometimes re-grading the slope so storm runoff sheds away from the house – exactly the kind of detail we’ve already handled up there.
