Unilock Construction in Los Altos Hills, CA | Seaside Contractors
We provide independent Unilock service across Los Altos Hills, from paver driveway installation to patio construction and retaining walls. What makes our Unilock work different here is simple: we’ve set these units on the steep, engineered lots of the Santa Cruz Mountains foothills long enough to know that a paver job in Los Altos Hills lives or dies by its base, its drainage, and its design review submittal. Call (833) 589-8103 for a free estimate on your Unilock project.
Why Los Altos Hills Residents Choose Us for Unilock Service
We’re a general contractor, not a paver subcontractor, and that changes how we approach a Unilock driveway or patio. Glen Sorrento grew up in Foster City watching lagoon-side homes get built and rebuilt, then spent two-plus decades working through nearly every project type the Peninsula throws at a contractor. That breadth matters when your Unilock patio has to tie into a retaining wall, a drainage swale, and a home addition all on the same hillside lot. We’re also clear about what we are and aren’t: we’re an independent contractor, not authorized or sponsored by Unilock. Our expertise comes from installs, not a manufacturer badge. For Unilock repair in Los Altos Hills homeowners, that means straight answers on which Unilock units will actually perform on a given slope, and which ones are a design-review headache waiting to happen.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Base failure and paver settlement on hillside driveways. The subgrade under many Los Altos Hills driveways wasn’t engineered for slope movement and seasonal saturation. Unilock units stay intact while the base beneath them shifts, creating dips and ridges that pool water and eventually crack units.
- Joint sand washout and edge-restraint creep on steep grades. During atmospheric-river events, runoff moves fast down Los Altos Hills driveways. Joint sand washes out of Unilock pavers, and edge restraints creep outward when drainage was designed for a flat lot. The pavers themselves shift, and the whole surface starts to spread.
- Efflorescence and surface staining on shaded patios. Brussels Block and Beacon Hill units in poorly drained or shaded Los Altos Hills placements never fully dry out through the wet season. White mineral deposits and organic staining set in, and they don’t rinse off with a garden hose.
- Retaining-wall batter and drainage failure on U-Cara walls. Expansive clay hillsides in Los Altos Hills push against walls that were installed without proper geogrid or backfill drainage. U-Cara walls lean, bow, or trap water behind them, which eventually causes face units to pop.
- Design review rejections on hardscape plans. Los Altos Hills’ design review board scrutinizes exterior hardscape details, from paver color to edge treatment. We’ve seen well-engineered Unilock plans get kicked back because the submittal didn’t address sight lines or material compatibility with the existing home.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Here’s what people outside Los Altos Hills don’t always grasp: the town’s design review board scrutinizes every exterior detail, including hardscape materials, roof pitch, and sight lines. A Unilock driveway or patio plan often has to clear design review before we can even schedule base excavation. That step doesn’t exist in neighboring cities. In Palo Alto or Mountain View, you pull a permit, schedule the excavator, and start digging. In Los Altos Hills, the town wants to see paver color, edge restraint type, and how the finished surface reads from the street. We’ve learned to build that review timeline into every Unilock job we quote here. It’s not a nuisance; it’s the reason so many Los Altos Hills properties keep their character. But it means a “two-week paver patio” in Los Altos Hills is realistically a four-to-six-week project, and we’d rather tell you that up front than have you watching a stalled excavator in your driveway. On a steep drive off a winding private lane above ZIP 94022, an older concrete apron had cracked and heaved where runoff from an unpaved shoulder poured across it every wet season. We tore it out, brought in engineered base to bed a Unilock Brussels Block driveway on proper slope to a new drainage swale, and set restrained edges that could take the grade without creeping. The driveway sheds atmospheric-river runoff instead of trapping it, and it cleared the town’s exterior review on the first submittal. That’s what Los Altos Hills Unilock work looks like when it’s done right.
Unilock Models & Products We Service in Los Altos Hills
We work with the full Unilock hardscape line, and we source genuine Unilock units plus matching edge restraints and polymeric joint sand rather than mismatched aftermarket pavers. Color and dimensional consistency only hold within the same production line, so when a patio needs repair, we match the lot number, not just the color name. The product families we service most often in Los Altos Hills include Unilock Brussels Block, a tumbled concrete paver that handles the town’s Mediterranean ranch and contemporary homes well; Beacon Hill Flagstone, which suits larger estate lots with its irregular flagstone look; Copthorne, a clay-look concrete paver that reads as traditional brick without the brick maintenance; and U-Cara, the retaining wall system we see most often on sloped lots where grade changes need terracing. When a patio or walk is settling, we diagnose the base first. If the Unilock units are sound, we re-base and re-lay rather than replace. Full replacement only makes sense when units are spalled, cracked, or a discontinued color can’t be matched.

FAQs – Unilock Construction in Los Altos Hills
Yes, and you should plan for it. Los Altos Hills requires exterior design review for hardscape work, and the review timeline runs weeks, not days. We build that timeline into every project schedule and prepare the submittal package ourselves: paver color samples, edge restraint details, drainage plan, and sight-line photos. Call (833) 589-8103 and we’ll walk you through what your specific project will need.
Unilock concrete pavers are non-combustible and generally qualify as fire-resistant hardscape under WUI defensible-space guidelines, though your specific plan should be confirmed with the Los Altos Hills fire marshal or your landscape architect. What matters for defensible space is the full zone design: a paver patio close to the house can actually help, but the surrounding plantings and mulch choices are what determine compliance. We’ll coordinate with your defensible-space plan so the hardscape and the landscaping work together.
Unilock units themselves handle the climate well; they’re dense, freeze-thaw rated, and don’t fade significantly in summer sun. What fails in Los Altos Hills is the base and drainage beneath them. Atmospheric-river winters saturate hillside subgrades, and that’s where settlement, joint sand washout, and edge creep originate. We spec deeper engineered base and drainage swales here than we would for Unilock in Stanford or a flat Santa Clara Valley lot, because the failure mode in Los Altos Hills is always water moving downhill fast.
For Mediterranean and Spanish-influenced homes, Unilock Copthorne in warm, earth-toned blends reads as traditional clay without the porous, spall-prone behavior of real brick. For ranch-style homes, Brussels Block in a charcoal or smoke color keeps the palette understated. Beacon Hill Flagstone suits the larger estate lots where an irregular, natural-stone look fits the setting. We’ll bring full-size samples to your site so you can see the color on your actual soil, in your actual light.
Re-leveling a settled Unilock patio or walkway typically runs in the paver patio installation range of $3,500 – $11,000 depending on square footage and how much base reconstruction is needed. Driveway re-basing on a hillside starts around $7,000 and goes up from there if we’re adding drainage or edge restraint retrofits. The best way to get an exact number is a site visit. Call (833) 589-8103 for a free estimate; Glen Sorrento will look at your base, your grade, and your drainage, and tell you straight whether it’s a re-level or a re-do.
