Unilock Construction in Palo Alto, CA | San Bernardino Contractors
We install and repair Unilock hardscape systems across Palo Alto as an independent contractor, working from the manufacturer’s published base-prep, bedding, and jointing specs rather than a dealer agreement. What makes our Unilock work different here is simple: we build paver fields for a city where design review, stormwater documentation, and tight infill lots aren’t optional add-ons, they’re the starting point. Call (855) 473-5620 to walk your project with us, and we’ll tell you straight what it needs.
Why Palo Alto Residents Choose Us for Unilock Service
We’ve installed and repaired enough Unilock product across the Midpeninsula to know each line’s quirks, from how Brussels Block settles on a clay-heavy base to where Beacon Hill Flagstone tends to chip if edge restraint is cut short. Ruben Castillo, our owner, grew up watching his uncle frame garages and reroof houses on a shoestring budget in San Bernardino, and that hands-on education stuck with him: if the base is wrong, no paver on top of it will hold. That’s why our crews in Palo Alto spend more time on excavation, compaction, and drainage than on the pretty layer. We’re authorized to work with Unilock as an independent contractor, not a manufacturer dealer, which means we spec the right Unilock unit for your exposure and load without pushing a catalog line that doesn’t fit your lot. For the full picture of what we do with this brand, see our Unilock sales & service page.

Common Unilock Construction Problems We Solve in Palo Alto
- Efflorescence bloom on Brussels Block and Beacon Hill units. Flat Palo Alto lots with no positive slope to the street hold winter rain in the joint sand, and when that moisture wicks up through the paver face and evaporates, you get that white, chalky film. We fix the drainage path first, then treat the surface. Re-sealing over a wet base just makes it bloom again next season.
- Joint sand washout and paver migration on driveways. Clay-heavy infill soil under Palo Alto driveways doesn’t drain on its own, and if polymeric sand was skimped during install, the first wet winter flushes it out. You see pavers start to drift and rattle under car tires. We lift the affected field, re-grade the base, and re-sand with Unilock’s specified polymeric product.
- Edge restraint failure and spalling at the curb cut. Freeze-free doesn’t mean load-free. Every car that turns into your driveway off a Palo Alto street puts concentrated stress on the apron edge where pavers meet the gutter. Without proper edge restraint, that edge crumbles. We fix the restraint, then replace the broken units.
- Retaining wall blockface settlement on Seneca Valley walls. Lots in the hills and near the creeks that cut through Palo Alto often have grade change toward the rear property line, and a Seneca Valley wall without geogrid and drainage aggregate behind it will eventually bulge or settle. We rebuild the wall from the base course up, adding the drainage layer the original install skipped.
- Pooling water at the garage door on mid-century driveways. The 1950s and 60s ranch tract homes south of Oregon Expressway were built with concrete drives pitched flat or slightly toward the garage, which was fine until the state started cycling wetter winters. Unilock pavers over a properly pitched base are one of the cleanest fixes we do for this, and we do it often in 94303 and 94306.
Unilock Service in Palo Alto: What Local Conditions Mean for Your Equipment
Here’s something you won’t hear from a generic Unilock page. Palo Alto’s design-review and green-building expectations push a lot of homeowners toward permeable paver systems and documented stormwater handling on even modest front-yard and driveway projects. We’re not talking about a checklist item; we’re talking about the city’s long-standing emphasis on getting water back into the ground rather than shunting it all to the storm drains that feed the Bay. So when we spec a Unilock permeable profile here, we’re in front of a plans examiner who’s actually looked at the base section. That means open-graded base detail, clean crushed rock, and no cutting corners on the storage layer. In a city like Palo Alto, a “standard” paver driveway is often anything but standard by the time it gets the city stamp. That’s the reality we build around, and it changes how we approach every Unilock job from Old Palo Alto down to Charleston Meadows. Serving this city well means understanding that, which is why we stay current on local requirements across our Palo Alto service area.
Unilock Models & Products We Service in Palo Alto
We work with the full Unilock residential lineup that makes sense for Los Altos Hills and Midpeninsula lots. Brussels Block, with its tumbled dimensional face, is our most-installed paver for driveway aprons and front walks, while Beacon Hill Flagstone handles patios and courtyard slabs with a more natural face. For permeable driveway fields, we spec Town Hall or Holland Stone depending on the city-mandated infiltration rate. Retaining grade changes, we build with the Seneca Valley wall system. On repairs and replacements, we use Unilock’s own units, edge restraints, and manufacturer-specified polymeric joint sand so the color, texture, and field pattern blend with what’s already there. Base and drainage materials are sourced to spec rather than brand, because a paver is only as good as what it sits on.

What drives cost here more than anything is the soil and the city. Tight infill lots mean more hand work and less machine access. Clay soil means deeper excavation and more imported aggregate. And if your project triggers design review, that’s a process cost you won’t see in a neighboring city’s quote. Our free estimates line-item the base, the units, the edge restraint, and the drainage so you know exactly what you’re paying for. Call (855) 473-5620 to have us walk the lot and put numbers on it.

FAQs – Unilock Construction in Palo Alto
Not always, but the city’s stormwater and green-building standards push hard in that direction, especially for front-yard hardscape that exceeds a threshold of impervious surface, and some areas in the flood-prone flatlands have additional requirements. The honest answer is that many Palo Alto driveway projects we bid end up spec’d permeable because the alternative requires so much stormwater mitigation work that the permeable base becomes the simpler, cheaper path. Call (855) 473-5620 and we’ll tell you what’s likely for your specific lot before you commit anything.
That’s efflorescence, and in Palo Alto it almost always means water sitting in the joint sand with nothing pulling it away from the surface. Flat lots and clay soil in Emerald Lake Hills create the exact conditions. The fix starts with correcting drainage under the field, then cleaning the pavers with an efflorescence cleaner and re-sanding the joints properly. Sealing over an undrained base traps the moisture and the bloom comes back, so we solve the water path first.
Yes, but it depends on the product line and whether Unilock still runs that color. Brussels Block and Beacon Hill are current lines with good color continuity, so we can blend new units in for localized repairs. If you have an older or discontinued color run, we’ll tell you up front what’s matchable and what isn’t before you spend a dime. Full replacement is only the honest recommendation when the base is structurally shot or the color is gone.
We start with drainage and grade. On a slope, that means stepping a retaining wall system like Seneca Valley with proper geogrid and a drainage aggregate core behind the wall, and on tight lots with narrow side-yard access, we hand-carry or use small equipment rather than tearing a fence line apart. Every West Menlo Park Unilock and Palo Alto lot we work has its own water path, and we build the paver system around that rather than fighting it.
Driveways typically run $7,000 to $18,000 and patios $3,500 to $11,000, depending on square footage, access, soil correction, and whether the city requires a permeable section. Lot conditions here can shift the number faster than anywhere else we work, so the only real way to price it is on-site. Call (855) 473-5620 for a free estimate with line items you can actually read.
