Unilock Construction in Portola Valley, CA | San Bernardino Contractors

We provide independent Unilock paver and retaining wall construction across Portola Valley, from full driveway replacements to patio repairs. The one thing that makes our Unilock work different here: we understand that Portola Valley’s town building department enforces a WUI ignition-resistant detailing review on hardscape that abuts your house, which means your paver edge restraints and joint sand have to be chosen for fire code, not just looks. Call (855) 473-5620 for a free estimate on any Unilock project.

Our crews have installed Unilock pavers and walls across the Santa Cruz Mountains for years, learning how their blends age under Portola Valley’s dry summers and winter runoff. We’re independent Unilock specialists, not manufacturer-authorized, so we recommend the right product for your site without a sales quota pushing a specific line. One contractor, every phase: from the roof down to the pavers, San Bernardino Contractors handles the whole home, and our Unilock sales & service work is backed by that full-scope capability.

Why Portola Valley Residents Choose Us for Unilock Service

Ruben Castillo, Owner at San Bernardino Contractors, grew up watching his uncle reroof houses and frame garages, and that hands-on education stuck with him. He completed his construction technology training at San Bernardino Valley College, where he got serious about load paths, drainage, and not cutting corners on anything structural. When it comes to Unilock pavers, that means we don’t just lay blocks on native soil and hope for the best. We excavate, compact, and build the base your site actually needs, especially on the steep, wooded lots that define Portola Valley.

Most of our clients come from referrals. A neighbor watches our crew clean up after themselves, sees the finished patio or driveway, and calls us next. That’s how we like it. We use Unilock OEM pavers and matching edge restraints for repairs, and we’ll substitute compatible polymeric sand or base aggregate from quality suppliers when the original components aren’t suited to Portola Valley’s drainage conditions. You pick the brand, we handle the build.

Common Unilock Construction Problems We Solve in Portola Valley

• Efflorescence bloom on Brussels Block pavers. After winter rains, white mineral deposits wick up through the joints when base drainage is poor. On Portola Valley lots with seasonal runoff from uphill open space, this shows up fast. We correct the drainage path and re-sand with a compatible polymeric product so the bloom stops returning.
• Edge restraint failure on steep driveways. Original spikes are often too short for Portola Valley’s sloped lots, and pavers start creeping and spreading within a few seasons. We pull the edge course, install deeper noncombustible restraints, and re-set the field so the driveway holds its lines.
• Joint sand erosion from diablo winds and runoff. Fall wind events strip loose sand from open joints, then weeds move in and the field destabilizes. We re-sand with an ember-resistant, stabilized product that handles the wind and the WUI review.
• Color fade and lippage on older Beacon Hill patios. When a patio was set directly on native soil without a compacted aggregate base, differential settling shows up as uneven edges and worn color. We rebuild the section with proper base so the repaired area matches the surrounding pavers and stays level.
• Base failure on paver driveways undercut by runoff. Steep, wooded lots in Portola Valley send stormwater and hillside seepage under the edge of a driveway, washing out fines and collapsing sections. We over-excavate, install a geotextile separator and compacted aggregate, then re-lay the pavers for a stable, long-term fix.

Unilock Service in Portola Valley: What Local Conditions Mean for Your Equipment

Here’s the Portola Valley-specific fact that changes how we build with Unilock: the town requires a separate WUI ignition-resistant detailing review for hardscape attached to the house. A paver patio or walkway that abuts siding or decking must be detailed with noncombustible edge restraints and ember-resistant joint sand before plan check clears. Neighboring Woodside or Menlo Park usually doesn’t enforce this on the same hardscape scope, and a generic paver contractor who works the whole Peninsula may not know to flag it. On a wooded lot off Portola Road, our crew rebuilt a failing Unilock Brussels Block driveway that had been undercut by seasonal runoff from an uphill open-space parcel. We over-excavated the saturated native soil, installed a geotextile separator and compacted aggregate base, then re-laid the pavers with new polymeric joint sand and deeper edge restraints. The finished drive now handles the fall diablo winds without sand loss and directs water away from the garage slab. That’s the difference between building to the plan check and building to Portola Valley’s actual conditions.

Unilock Models & Products We Service in Portola Valley

We work with the Unilock lines most common in Portola Valley and the wider Portola Valley service area, including Brussels Block, Beacon Hill, Town Hall, and Eco-Priora. Our approach is simple: we use Unilock OEM pavers and matching edge restraints for repairs so the color, texture, and dimensions stay consistent. For replacement aggregate and joint sand, we’ll go with quality compatible products when the OEM option isn’t the right fit for a particular site’s drainage or fire-code requirements. We stock common edge restraint profiles and stabilized joint sands locally so the turnaround on a Portola Valley repair doesn’t drag out.

FAQs – Unilock Construction in Portola Valley

Does Portola Valley require a separate permit for a Unilock paver driveway or patio?

Yes, Portola Valley’s town building department treats hardscape attached to the house as part of the ignition-resistant detailing review, so a paver driveway or patio that abuts siding or decking typically needs its own permit review. Most Peninsula towns fold hardscape into a general remodel permit, but Portola Valley does not. Call (855) 473-5620 and we’ll walk you through what applies to your scope.

How does Portola Valley’s WUI code affect the choice of Unilock pavers and edge details?

It requires noncombustible edge restraints and ember-resistant joint sand wherever hardscape meets the house, plus careful detailing at the transition to siding or decking. Unilock pavers themselves are concrete, so the product choice is less affected than the edge and sand details. We specify those details to clear plan check the first time. Call (855) 473-5620 for an exact scope review.

My Unilock Brussels Block driveway has white stains – what causes that and can it be fixed?

That’s efflorescence, a mineral salt bloom that wicks up through cementitious pavers when moisture moves through the base and evaporates at the surface. Here in Portola Valley, poor base drainage or runoff from an uphill parcel makes it worse. We fix it by correcting the drainage and re-sanding the joints, and the stains can be cleaned with a compatible efflorescence remover. If the base is failing, we’ll tell you honestly whether a rebuild makes more sense than repeated cleaning.

Can you match existing Unilock pavers if only part of my patio or walkway needs replacement?

Yes, we match the exact Unilock product line, color, and finish from the same OEM supply chain, and we blend the repair into the surrounding field so the transition isn’t obvious. Expect slight color difference if the original pavers have years of sun fade, which is normal for any product. Call (855) 473-5620 for a free on-site match.

We are on a steep, wooded lot with expansive soils – what base prep does a Unilock paver driveway need here?

It needs over-excavation to remove the saturated or expansive native soil, a geotextile separator, a compacted aggregate base built in lifts, and deeper edge restraints than a flat-lot install. On steep Portola Valley lots, we also route drainage away from the base so seasonal runoff doesn’t undercut it. Call (855) 473-5620 and we’ll assess your specific slope and soil before quoting.
