Why Los Altos Residents Choose Us for Unilock Service

Hardscape is only as good as what’s underneath it. That’s where most Los Altos paver jobs fall apart, and it’s where we spend the most time. Glen Mossier grew up in Foster City’s Marlin Cove neighborhood watching lagoon-side homes get rebuilt after water damage, and the lesson stuck: base prep and drainage decide everything. Build it right the first time, and you won’t be rebuilding it in ten years. We apply that same thinking to every Unilock driveway and patio we put in across the 94022, 94023, and 94024 ZIP codes, plus Loyola Unilock service nearby. Los Altos residents call us because we name the actual product, explain the soil condition beneath their lot, and give them a number before anyone picks up a shovel.

We work with Unilock’s full component system: edge restraint, polymeric sand, and wall caps. We source from regional distributors, not big-box shelves, because color and dimensional consistency depend on getting the same lot numbers. If you’re comparing quotes, ask every contractor how deep they excavate and what they compact with. The answers tell you more than the logo on their truck.

Common Unilock Construction Problems We Solve in Los Altos

Here’s what we see most often when a Unilock installation starts misbehaving in Los Altos:

• Edge settling and lippage along driveway aprons. Los Altos clay expands when wet and shrinks when dry. If the base wasn’t over-excavated and compacted in lifts, the pavers near the street edge start dropping and creating trip hazards within two or three seasons. We rebuild the base properly, not just the surface.
• Efflorescence on Brussels Block and Beacon Hill. White mineral staining blooms after wet-winter cycles when the setting bed holds moisture against a poorly drained subgrade. We diagnose the drainage issue rather than just pressure-washing the surface, because the stain comes back if water is still trapped underneath.
• Polymeric sand washout on slope transitions. Los Altos lots rarely sit flat. Where runoff concentrates, especially downhill of mature canopy that keeps the surface damp, the joint sand erodes and weeds move in. The fix is re-grading and proper drainage, then re-sanding with Unilock’s own polymeric product.
• Root heave lifting patio slabs and wall footings. Heritage oaks and redwoods send roots well past their drip lines. Pavers built too close to a critical root zone will eventually lift and crack. This is a Los Altos-specific problem that requires rethinking the hardscape footprint, not just patching the surface.
• Improper base depth under second-story addition tie-ins. When we add a home addition and the lot’s hardscape was put in by someone who treated Los Altos clay like stable soil, the new foundation work can expose the old shortcuts. We handle both scopes, so the base under your new patio matches the standard of the addition itself.

Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment

Here’s the thing most homeowners don’t know until a project stalls: Los Altos’ tree-protection ordinance can require an arborist report and a root-zone buffer before any excavation happens. That applies to paver driveways and patios, not just home additions. A heritage oak’s critical root zone may force a hardscape redesign that shifts the footprint and drainage away from the tree entirely. We’ve handled this more times than we can count. On a ranch home off University Avenue near downtown Los Altos, the owners wanted a Brussels Block driveway and a Beacon Hill patio, but the heritage oak put part of the intended footprint inside its protected root zone. We also handle similar cases with Unilock service in Stanford. We pulled the hardscape back to the buffer line, over-excavated the clay in compacted lifts, set Unilock edge restraint and polymeric sand, and pitched surface drainage away from the root zone. Those pavers stayed tight and level through the following wet season. That’s not catalog knowledge. That’s Los Altos knowledge.

Unilock Models & Products We Service in Los Altos

We install and service the full practical Unilock range for residential Los Altos work:

• Brussels Block: tumbled paver, our default recommendation for driveways because the aged surface hides tire marks and stands up to heavy point loads.
• Beacon Hill: tumbled, estate-style paver for patios and walkways where you want a wider, more formal look.
• Elegance: smooth, large-format slab paver for cleaner sight lines and a more contemporary feel.
• Brussels Dimensional: rectangular wall block for seat walls, planters, and grade transitions.

When we repair existing Unilock work, we use Unilock’s own matching components rather than substituting generic block. The color and dimensional consistency depend on it. Our honest stance: the paver is rarely the thing that fails. When a driveway or patio misbehaves in Los Altos, it’s almost always the base and drainage underneath. We rebuild that properly instead of selling you new pavers you don’t need.
