Unilock Construction in Los Altos, CA | Seaside Contractors
We’re Seaside Contractors, and we build Unilock paver driveways, patios, and retaining walls across Los Altos as our General Contractor in Los Altos. What makes our Unilock work different here is simple: we design the base for Los Altos’s expansive clay and heritage-oak root zones before we lay a single paver. If you’re pricing a Unilock project in the 94022, 94023, or 94024 ZIP, call (833) 589-8103 for a free estimate. We’re an independent contractor, not a manufacturer affiliate.
Why Los Altos Residents Choose Us for Unilock Service
Glen Sorrento grew up watching Peninsula homes get built and rebuilt, and he’s spent the two-plus decades since learning what holds up and what doesn’t. That’s the lens we bring to Unilock work in Los Altos. We don’t just install Brussels Block or Beacon Hill because the catalog looks good. We spec the paver thickness, the edge restraint, and the open-graded base depth for the soil report and the lot conditions in front of us.
We use genuine Unilock units and the manufacturer’s specified base, edge-restraint, and polymeric sand on every job. Mixing in generic pavers undercuts the whole system. For hardscape that’s already failing, we’ll reset sound pavers after we rebuild the base. Full replacement only happens when the aggregate itself has broken down or the layout no longer makes sense for the lot. That’s the kind of straight answer Los Altos homeowners expect. It’s also why our Unilock sales & service work starts with what’s under the paver, not what’s on top of it.

Common Unilock Construction Problems We Solve in Los Altos
Unilock makes good product. But Los Altos has a way of exposing every shortcut in the base and drainage layers. Here’s what we see most often:
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. White mineral staining that shows up on shaded pavers under heavy oak canopy. The pavers aren’t failing; trapped moisture from the wet season is wicking through and leaving salts behind. We address the drainage and the subbase, not just the surface stain.
- Edge spalling at the driveway apron. Los Altos’s expansive clay shrinks in the dry summer months. The soil pulls away from the concrete collar, and the paver edges lose support. Chipped corners follow. We rebuild the edge restraint with a deeper, properly compacted base so the paver line stays locked.
- Rutting in paver driveways. When the open-graded base isn’t deep enough for Los Altos’s soil movement, driveways start to rut and pavers lip under load. Fixing it means pulling the section, re-excavating, and compacting lifts the right way.
- Joint sand washout on U-Cara walls. Runoff from a neighboring slope that wasn’t intercepted before the wall face erodes the joint sand and pushes the wall out of batter. We re-grade the drainage path, then reset the course.
- Root-driven base heave near heritage oaks. A mature coast live oak’s roots don’t stop at the trunk. When a base is poured or compacted too close to a root zone, the pavers move. Los Altos oak lots make this a routine design constraint, not an exception.
Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment
Here’s the thing about Los Altos that most paver contractors from outside the area don’t plan for: the heritage coast live oak. On many lots, a protected oak within the drip line triggers a city tree-protection review. That review can force a Unilock driveway or patio base to stop several feet short of the root zone. We design around it. That means a paver layout that transitions to mulch or a low deck at the oak edge instead of paving lot-line to lot-line. It’s not a compromise; it’s the difference between a paver system that performs for decades and one that heaves in three years. On a 1950s ranch tear-down lot off Springer Road in the 94024 ZIP, the homeowner wanted a Brussels Block driveway and a Beacon Hill patio, but a heritage coast live oak’s drip line crossed the proposed apron. We also provide Loyola Unilock service for similar projects. We fenced the root zone, pulled the paver base back by the required setback, and used a permeable U-Cara border wall at the grade change. The pavers sit on compacted aggregate, not the tree’s roots, and the oak stayed protected through inspection. That’s the local knowledge you pay for with Unilock construction in Los Altos.
Unilock Models & Products We Service in Los Altos
We install and service the full structural lineup: Brussels Block, Beacon Hill Flagstone, Town Hall, and the U-Cara Modular Wall System. Most of our Los Altos clients land on Brussels Block for driveways that see daily vehicle traffic and Beacon Hill for patios where a more irregular, flagstone look fits the older ranch-home character. For retaining walls and grade changes, U-Cara gives us a modular block that works as a permeable border, not just a wall. We keep common Unilock units and edge-restraint components in local stock so a Los Altos project doesn’t stall waiting on a truck from the distributor. When a repair calls for a specific color blend or a discontinued run, we pull from Unilock’s current lines and blend where the lot allows.

FAQs – Unilock Construction in Los Altos
It usually won’t stop the project, but it will shape the layout. Los Altos requires tree-protection review when construction falls within a protected oak’s drip line. We design the paver base to stop short of the root zone with a compliant transition, so the driveway often gets built around the tree rather than through it. Call (833) 589-8103 and we’ll tell you what’s possible on your lot.
Expansive clay shrinks and swells with the seasons. That movement means the open-graded base under Los Altos pavers must be deeper and better compacted than a spec written for stable sandy soil. We over-excavate and compact in lifts so the pavers don’t rut or lip when the ground dries out in summer. The base depth is a soils decision, not a one-size-fits-all. For an exact number on your lot, call (833) 589-8103.
Yes, with scheduling and sequencing that respects the wet window. We avoid compacting saturated base material and we time paver placement between storm cycles. Some weeks the weather simply wins. But a well-managed rain-season install is common in Los Altos, especially when the alternative means waiting until June. Call (833) 589-8103 to talk through the timeline on your project.
Brussels Block is a tumbled, rectangular paver with a more finished, consistent edge, and it’s our standard recommendation for Los Altos driveways because it handles vehicle loads well. Beacon Hill is an irregular flagstone profile that reads more natural and works beautifully on patios and walkways, but its varied joints mean more care under tire traffic. We’ll spec the right one for the use. Estimates are free, so call (833) 589-8103.
Most paver patios don’t need one, but retaining walls over a certain height and any work near a protected oak often do. Los Altos reviews tree-protection and grading carefully, and we handle the permits and inspections as part of the job. If a wall is part of your plan, call (833) 589-8103 and we’ll flag what Los Altos will ask for before you commit to a design.
