Unilock Construction in Los Altos Hills, CA | Daly City Construction
We provide independent Unilock paver, wall, and step installation and repair across Los Altos Hills. We’re not a Unilock dealer or authorized repair center. We’re a Los Altos Hills General Contractor that has installed and rebuilt Unilock hardscapes on hillside estates here for years, and the one thing that separates our work is knowing the town’s design review and drainage requirements cold before the first paver gets laid. Call us at (866) 505-5254 to talk through your project.
Why Los Altos Hills Residents Choose Us for Unilock Service
Most contractors in Los Altos Hills can lay pavers. Fewer can tell you why a Brussels Block driveway heaved after two winters, or whether a Pisa2 wall needs a geogrid rebuild or just better drainage. That’s the difference Noel Cabrera brings to every Unilock job. Noel grew up in the Westlake district of Daly City, spent years swinging a hammer across San Mateo and San Francisco counties, and came up doing hillside work where retaining walls and runoff control aren’t optional features. We know the Unilock sales & service landscape better than most, and we bring that product knowledge directly into Los Altos Hills service area projects.
We run this work as a our Home Remodeling in Los Altos Hills team, not a hardscape-only crew. That means when your Unilock driveway replacement uncovers a failing storm drain or a rotted fence line at the property edge, we handle it under one contract instead of sending you back out to hire someone else. One point of contact, from demolition through final town sign-off.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Efflorescence and salt bloom on Brussels Block and Beacon Hill surfaces. The wet winters here push moisture up through steep clay soils, and Los Altos Hills lots with poor sub-base drainage develop white mineral deposits faster than flat-lot properties. We clean the bloom, then fix the drainage that’s causing it so it doesn’t come back in March.
- Paver heaving and joint sand loss on driveway grades over 12%. Los Altos Hills private roads and driveways run steep, and winter runoff destabilizes bedding layers quickly. We rebuild these with geogrid-reinforced base and polymeric sand that holds the joints on grades most installers won’t touch.
- Pisa2 retaining wall creep and face cracking. Multi-acre slopes with seasonal springs generate hydrostatic pressure that undersized drainage can’t handle. Wall blocks tilt, crack, or creep forward. The fix is almost never just stacking new block; it’s rebuilding the drainage and reinforced base behind it.
- Eco-Priora permeable paver clogging from clay fines. Clay particles wash downslope and pack into the paver joints, cutting infiltration and creating ponding at driveway toes. We clean and restore the permeable layer, then add a sediment control detail upstream where the clay’s coming from.
- Lot-coverage and ridgeline compliance issues on new hardscape plans. The town’s design review catches hardscape that pushes lot coverage over the limit or breaks ridgeline sightlines. We draw Unilock driveway and patio plans to scale with pervious surfaces accounted for, so the permit doesn’t stall.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Los Altos Hills’ design review and hillside development permit process is the thing that changes everything about Unilock work here. This isn’t a flat-lot city where you submit a simple site plan and start digging. The town requires nearly all substantial work to pass design review, and that means your Unilock paver driveway or patio gets drawn to scale with lot coverage, ridgeline limits, and pervious surface calculations shown. On a steep private road off La Paloma Road, we rebuilt a Unilock Brussels Block driveway that had heaved and lost joint sand after two winters of runoff. We pulled the failed base, installed a geogrid-reinforced aggregate section with a properly sized drainage swale, and re-laid the pavers with polymeric sand. The client passed town review for the revised hardscape plan, and the driveway has held through two more rainy seasons. That’s what Unilock work in Los Altos Hills actually looks like. If your contractor doesn’t understand the hillside permit and drainage requirements before quoting, you’ll pay for it later in plan revisions or re-inspection fees.
Unilock Models & Products We Service in Los Altos Hills
We install and repair the full Unilock line we regularly see on Los Altos Hills estates: Brussels Block for driveways and heavy-traffic surfaces, Beacon Hill Flagstone for patios and pool decks, Eco-Priora permeable pavers where town drainage rules require pervious hardscape, and Pisa2 wall units for segmental retaining walls on tiered lots. For repairs and additions, we use genuine Unilock pavers, wall units, and caps to match color and dimension. For the hidden layers, geogrid, filter fabric, and polymeric joint sand, we source quality aftermarket materials where the proprietary version adds no value on a hillside. Small paver pop-ups are worth repairing. A failing wall on a steep lot usually means rebuilding the drainage and base, not just swapping block.

What drives cost here more than anything is hillside access and base preparation. Steep private roads make material delivery and concrete staging slower. The drainage corrections and geogrid reinforcement that Los Altos Hills slopes demand add labor and material the flatlands rarely need. A free estimate includes a walk of the site, a check on whether the town’s design review applies to your scope, and a line-item quote so you see exactly where the money goes.

FAQs – Unilock Construction in Los Altos Hills
Yes, for nearly every substantial hardscape project. Los Altos Hills requires a hillside development permit and design review for most new hardscape work, and that includes Unilock paver driveways and patios when they affect lot coverage or drainage. We prepare the scaled plans and drainage calculations the town wants to see, and we pull the permits and stand with you through inspection. Call (866) 505-5254 and we’ll tell you whether your specific project triggers review.
Because steep grades and winter runoff wash the sand out faster than on flat lots. Shrink-swell clay under the bedding layer also destabilizes the base, which lets pavers shift and joints widen. We rebuild these driveways with a geogrid-reinforced base and polymeric sand, which locks the joints and holds on grades over 12%. If your driveway needs that fix, call (866) 505-5254 for a site assessment.
Pisa2 can handle significant slopes when the base and drainage are engineered correctly. The failures we see in Los Altos Hills aren’t the block giving out; they’re undersized drainage behind the wall letting hydrostatic pressure build until the wall creeps or cracks. We rebuild Pisa2 walls with proper geogrid, drainage stone, and outlet pipes. The block is the visible part. The drainage is what holds it.
Permeable pavers clog when clay fines from upslope wash into the joints, and on Los Altos Hills properties with steep terrain that happens every rainy season. We clean the paver layer, restore joint aggregate, and install a sediment control detail upslope to catch fines before they reach the pavers. It’s a repeat maintenance item on clay slopes. We can set you up on an annual cleaning schedule.
Small settled sections are usually worth Unilock repair in Loyola and Los Altos Hills—we pull the affected pavers, fix the localized base issue, and re-lay them with matching Unilock units. But if the settlement runs across a long stretch of driveway on a steep grade, you’re likely looking at a base failure that will keep spreading. We’ll tell you honestly which one you have. Call (866) 505-5254 and we’ll take a look.
