Unilock Construction in Los Altos Hills, CA
Unilock repair in Los Altos and construction in Los Altos Hills is not a flat-lot paver job. We install and repair Unilock segmental pavers, retaining walls and permeable hardscape on graded hillside estates where the town’s site-development review, private wells, septic systems and slope-ordinance rules dictate the base, drainage and edge-restraint spec long before the first paver goes down. Call (877) 373-9230 for a free estimate on Unilock work that actually holds on a Los Altos Hills slope.

Garden Grove Contractors is an independent Unilock service provider. We are not manufacturer-affiliated or authorized by Unilock, and we say that plainly because it matters: we spec what your hillside lot needs, not what a single supplier’s program pushes. Our crews work with Brussels Block, Beacon Hill, Yorkville and U-Cara systems every season, and we build them to Los Altos Hills grading and drainage standards, not to a valley-floor standard that fails the first winter.
Why Los Altos Hills Residents Choose Us for Unilock Service
Most paver contractors learn Unilock on flat suburban lots. Los Altos Hills is a different animal: one-acre-plus estates, steep grades, private lanes the town controls, and a geotechnical review on nearly every exterior project. We’ve spent enough seasons on these hillside sites to know which Unilock profiles hold their joints under concentrated runoff from a narrow private lane, and which wall systems need stepped geogrid rather than a straight run of block.
Noel Cardenas, our owner, came up through a vocational trades program and has spent years on structural remodels and exterior builds that have to hold up against real weather cycles. He treats a retaining wall on a graded Los Altos Hills General Contractor lot as a structural element, not a landscaping accent. That’s the standard we bring to every Unilock installation and repair in the 94022 zip code.
We use genuine Unilock units, edge restraints and compatible joint sand for anything visible or structural. For base aggregate and geogrid where the spec allows, we source quality aftermarket materials matched to the slope and surcharge. The result: a paver field or wall that’s designed for Los Altos Hills, not for a showroom.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Paver creep on sloped driveways. When a base isn’t stepped and keyed for the grade, pavers slide downhill and joints open up. On Los Altos Hills driveways that drop six feet or more across a short run, this shows up within two wet winters. We pull the field, rebuild the base in stepped lifts, and add toe restraint so the pavers stay put.
- Joint-sand washout after heavy rain. The foothills above the valley floor catch serious winter rain. Where a paver field sits above a retaining wall without a proper drainage path, water flushes the joint sand out and leaves the surface loose. We intercept that water before it crosses the pavers and replace the sand with a compatible Unilock joint product.
- Retaining-wall settlement or bulging. When the geogrid and drain rock weren’t engineered for the retained height and the surcharge behind it, a wall starts to lean. On a Los Altos Hills hillside that surcharge is often a driveway, a pool deck, or a guest structure. We rebuild with the right grid depth and drain rock, and we don’t patch a structural problem with a cosmetic fix.
- Staining and rutting where a paver apron meets a private lane. Los Altos Hills private lanes are narrow and town-maintained, which means runoff concentrates where the lane meets your paver apron. Without a catch drain or a swale to intercept it, that water carves ruts and leaves staining across the Unilock surface. We tie a drainage outlet into the lot’s existing path and repair the apron.
- Efflorescence on under-drained slopes. Mineral deposits bloom across pavers when water moves through the base and evaporates at the surface. On Los Altos Hills lots with poor subgrade drainage, this is a recurring nuisance. We remove the efflorescence and fix the drainage path, because cleaning alone doesn’t stop it from returning.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Project
Here’s the thing about Los Altos Hills that doesn’t show up in a Unilock catalog: because the town, not the county, controls the site-development permit and private lanes, a paver driveway or patio has to be designed around the property’s drainage outlet and retaining-wall loads before the first course goes down. That grading-and-drainage review is usually the long pole in the schedule, not the pavers themselves. A homeowner can pick out Brussels Block in an afternoon, but the permit path runs through geotechnical review, slope analysis, and a drainage plan that ties into the lot’s well-and-septic layout.
On a steep drive off a town-maintained private lane in the Los Altos Hills foothills, an owner’s Brussels Block apron had crept downhill and washed out joints after two wet winters. We pulled the field, rebuilt the base in stepped lifts keyed to the grade, added toe restraint and a catch drain tied to the lot’s drainage outlet, and relaid the Brussels Block. That drive has held its lines through the following rainy season because the drainage got fixed, not just the surface.
This is what separates a Unilock job that looks good in June from one that still holds in February: the base, the restraint and the drainage path. On a graded, well-and-septic lot in Los Altos Hills, those three things matter more than the paver color.
Unilock Models & Products We Service in Los Altos Hills
We install and repair the full range of Unilock systems homeowners in Loyola and Los Altos Hills actually use. Brussels Block remains the most common paver for driveways and aprons because it reads as classic stone without the premium tag. Beacon Hill shows up on pool decks and patios where a softer, more textured surface fits the setting. Yorkville handles larger-format paver projects where the scale matches a big estate. And U-Cara is our go-to retaining wall recommendation on hillside lots because it takes the lateral pressure of a graded slope when the wall is engineered right.
For parts, we use genuine Unilock units and edge restraints on anything visible or structural. For base aggregate and geogrid where spec allows, we use quality aftermarket materials matched to the slope and surcharge. We keep common Unilock profiles and joint sands available for Los Altos Hills turnarounds, so a repair doesn’t stall waiting on a pallet from out of state.

FAQs – Unilock Construction in Los Altos Hills
Are Unilock retaining-wall systems suitable for the retaining walls on my hillside lot? Yes, U-Cara and other Unilock wall systems work on Los Altos Hills hillside lots when they’re engineered for the retained height, surcharge and drainage conditions on your specific grade. A wall that’s just stacked and backfilled will bulge or settle; a wall built with the right geogrid depth, drain rock and toe detail will hold. Call (877) 373-9230 for a site evaluation.
Are you an authorized Unilock dealer or installer? No, and we’re direct about that. Garden Grove Contractors is an independent Unilock service provider, which means we spec the units, base and restraint your hillside lot needs, not whatever a manufacturer program requires. We source genuine Unilock units and compatible joint materials for every visible and structural component.
How long does an Unilock paver driveway repair take in Los Altos Hills? A relay-and-rebase on a standard driveway typically takes three to five working days once we’re on site. A full replacement with drainage work and geotechnical review runs longer, and the town’s site-development permit is often the schedule driver. We’ll give you a written timeline with the estimate.
Do you use OEM or aftermarket parts for Unilock repairs? We use genuine Unilock units, edge restraints and compatible joint sand for anything visible or structural. For base aggregate and geogrid where the spec allows, we use quality aftermarket materials. On a settled wall or a rocker paver field, we repair by relay-and-rebase when the units and base are sound, and recommend full replacement when grading or drainage is the root cause.
How much does Unilock paver installation cost in Los Altos Hills? Paver driveway installation in Los Altos Hills runs $7,000 to $18,000; paver patios land between $3,500 and $11,000. Your hillside’s grade, drainage path and access from the private lane move the number. Call (877) 373-9230 for an exact line-item quote, free.
