Unilock Construction in Los Altos, CA | Gold Star Contractors
We provide independent Unilock installation and repair across Los Altos, including the 94022, 94023, and 94024 ZIP codes, as well as Loyola Unilock service. What sets our work apart here is that we build every paver driveway, patio, and U-Cara wall around Los Altos’ own plan-check process and foothill-edge fire requirements, not a generic spec sheet. You can reach us at (833) 382-8544 for a free estimate on any Unilock project.
Why Los Altos Residents Choose Us for Unilock Service
We’ve laid Unilock pavers through enough Los Altos rebuilds to know how their systems actually behave on this town’s clay soils, mature tree root zones, and steep driveway aprons rather than just what the catalog promises. Our crews work with genuine Unilock units, matching edge restraints, and wall connectors for anything visible or structural, and quality base aggregate, geotextile, and polymeric sand underneath. The paver is the finish. The base is the job. Noel Carranza, our General Contractor in Los Altos, grew up watching older tract homes get renovated block by block in Anaheim, and he brings that same eye for how buildings actually go together to every Los Altos project we take on. One call, done right, that’s the only way he knows how to run a job.

Common Unilock Construction Problems We Solve in Los Altos
- Brussels Block driveway rutting on sloped lots. Los Altos has plenty of post-war ranchers on lots that drain toward the street cut. When a Brussels Block driveway is installed on a base compacted to flat-lot specs, the first wet winter pushes pavers downhill into ruts and shifts. We cut, re-grade, and re-compact the subgrade before relaying anything.
- Efflorescence and polymeric sand washout on Beacon Hill patios. Ranch lots in Los Altos often have sprawling turf, and lawn irrigation set too close to a Beacon Hill patio leaches water through the joints. The result is white mineral staining and sand that washes out after the first season. We correct the drainage slope and re-sand with a properly compacted joint filler.
- U-Cara wall settlement and fascia separation. Retaining walls on Los Altos slopes need a geogrid tie-back sized for the retained soil and a footing keyed below the clay line. We regularly see U-Cara walls where that step was skipped, and the fascia courses begin to separate from the block. Repair means re-excavating the tie-back zone, not just pushing the face back in place.
- Edge restraint pull-out at steep driveway aprons. Los Altos approaches are steeper than most flat-lot cities, and old concrete aprons overlaid with pavers rather than cut out create exactly the condition where edge restraints fail and pavers creep. We remove the old apron, install a proper restraint, and relay the paver edge cleanly.
- Base failure from clay expansion. The clay soil under much of Los Altos expands and contracts with winter moisture, and a thin or poorly compacted base underneath any Unilock product will telegraph that movement. We build base depths and geotextile separation specific to the soil conditions we find on each lot, not a one-size number from a catalog.
Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos permits are plan-checked per trade through the city’s own building division, which is slower than the county service that neighboring cities use. Projects near the foothill edges can trigger Chapter 7A ignition-resistant exterior requirements under California’s wildland-urban-interface building code, so a paver patio or U-Cara wall tied to a new hardscape permit can sit in plan check while the crew waits. Hardscape plans here increasingly have to address defensible-space detailing and noncombustible-deck-edge specifications that flat-lot installs in, say, Unilock service in Mountain View or Sunnyvale never touch. For Unilock owners, that means a paver driveway or retaining wall project in the 94022 foothill-side streets often takes longer to permit than the physical install itself. We factor plan-check lead time into every schedule we write and coordinate the permit submission so the crew isn’t standing idle on your lot. If you’re in Los Altos Hills or along the edges of 94024, the Chapter 7A conversation should happen before a single paver is ordered.

AfterUnilock Models & Products We Service in Los Altos
We install and repair Brussels Block pavers, the U-Cara modular retaining wall system, Beacon Hill paver slabs, and Town Hall and Courtstone driveway pavers. For anything visible or structural we use genuine Unilock units and their matching edge restraints and wall connectors. Where a section has failed only at the base or sand, we lift, re-base, and relay the existing pavers rather than sell a full replacement. Full replacement only makes sense when the Unilock units themselves are spalled, cracked, or discontinued in a shade that can’t be matched. For faster Los Altos turnaround, we keep common edge restraints, polymeric sand, and base aggregate stock locally, and we order Unilock units directly so you’re not waiting on a distributor’s regional schedule. For more on our broader brand work, see our Unilock sales & service page.
Unilock Service Pricing in Los Altos

What drives the cost in Los Altos is base work. On a steep lot or clay-heavy soil, the excavation, geotextile, and compaction take more labor than the paver laying itself, and that’s where the difference between a $9,000 driveway and a $15,000 one lives. Every free estimate includes a site walk, base assessment, drainage check, and a written line-item quote before any work begins. Call (833) 382-8544 to schedule yours.

FAQs – Unilock Construction in Los Altos
Yes. Los Altos plan-checks hardscape permits through its own building division, not a county service, so a new paver driveway, patio, or retaining wall over a certain height needs city review. Projects near the foothill edges can also trigger Chapter 7A exterior requirements. We handle the permit application and coordinate with the city so the schedule reflects plan-check reality, not wishful thinking. Call (833) 382-8544 and we’ll tell you exactly what applies to your lot.
We re-grade and re-compact the subgrade to match the actual drainage path of the lot, then install geotextile and a proper aggregate base with an edge restraint at the apron. The original failure is almost always a base built to flat-lot spec on a slope that drains toward the street cut. Fixing the base is what keeps the pavers from moving, not switching paver brands. Call (833) 382-8544 for a site assessment and a quote that’s free.
In most cases, yes. If the Unilock units themselves are intact, we lift them, rebuild the base and drainage layer, and relay the same pavers. You pay for base work and labor, not new material. We only recommend full replacement when the pavers are spalled, cracked, or a discontinued shade that can’t be matched. Call (833) 382-8544 and we’ll tell you which applies after a site walk.
Efflorescence usually clears up on its own once the moisture source is corrected. The real issue on Los Altos ranch lots is lawn irrigation too close to the patio edge, which keeps feeding the mineral stain and washing out the polymeric sand. We adjust the irrigation or drainage slope, then re-sand the joints. New pavers are rarely needed. Call (833) 382-8544 for an exact diagnosis.
We remove the old joint sand, correct the drainage slope or irrigation overspray that caused the washout, and re-sand with a properly compacted polymeric joint filler. Winter rains in Los Altos are concentrated enough that any drainage flaw shows up quickly, so we fix the cause, not just the symptom. Call (833) 382-8544 and we’ll schedule a free estimate before the next storm season.
