AfterUnilock Construction in Los Altos, CA | Rowan Construction Group Palo Alto
Unilock paver installation and repair in Los Altos typically runs $3,500-$18,000 depending on scope, with most driveway and patio projects requiring geotechnical review due to the city’s expansive clay soils and Protected Tree Ordinance. We’re Rowan Construction Group Palo Alto, an independent Unilock service provider - not authorized or endorsed by Unilock - and we’ve installed and repaired Brussels Block, Beacon Hill, Umbriano, and Town Hall systems across Los Altos since 2007. Call (650) 446-9092 to schedule your free written estimate.
Why Los Altos Residents Choose Us for Unilock Service
We’ve worked on enough Los Altos lots to know the difference between a Foothill Expressway-area ranch with post-and-pier foundation issues and a teardown-rebuild near the Country Club where the new owner wants a paver driveway engineered for a Tesla and a weekend SUV - often after completing Los Altos Kitchen Remodeling on the same property. Grant Rowan, our owner, grew up tagging along on residential jobs in the hills above Sunset and later trained in structural framing and concrete forming at Los Angeles Trade-Technical College. That background shows up in how we quote Unilock work: we measure the substrate, name the geotextile spec, and put the number in writing before anyone picks up a spade.
Our crews carry Unilock sales & service expertise across the Peninsula, and we stock OEM Brussels Block, Beacon Hill, Umbriano, and Town Hall units with matching Edge Restraints and polymeric sands for Los Altos repairs. Aftermarket lookalikes rarely match Unilock’s tumbled or shot-blast textures, and they fail at different rates - we don’t use them. Every project starts with a flat written price and written scope under Clause 1 of The Haven Standard. No work proceeds on a change until the change order is signed. That’s the discipline that’s kept our projects within a few percent of the agreed cost across 4,000-plus jobs.
Common Unilock Construction Problems We Solve in Los Altos
- Efflorescence bloom on Brussels Block and Beacon Hill - Los Altos’s wet winters and heavy irrigation overspray near planting beds leave a white salt haze on paver surfaces. We clean with a proprietary efflorescence remover, then reseal with a breathable silane-siloxane treatment that won’t trap moisture.
- Edge spalling and joint raveling on Town Hall and Umbriano - Common in older driveways near Foothill Expressway where the base was compacted over expansive clay without geotextile separation. The clay swells and contracts, the base migrates, and the paver edges chip out. We excavate to spec, add separation fabric, and rebuild.
- Polymeric sand washout after late-season El Niño events - Sloped Los Altos driveways and patios lose joint sand to concentrated runoff, leaving gaps that collect dirt and sprout weeds. We re-sweep with high-performance polymeric sand rated for joint widths and reactivate with a controlled mist.
- Paver settlement and lippage at garage aprons - Original 1950s-70s ranch-era concrete subbases weren’t engineered for modern vehicle loads. We break out the old slab, re-engineer the base with crushed aggregate and proper compaction, then reset matching Unilock units flush.
- Base failure on teardown-rebuild lots - New two-story custom builds press against Los Altos’s strict FAR limits and 28-foot height cap, concentrating loads on tighter driveways. We design the paver base for the actual vehicle weight, not the original 1962 sedan.

AfterUnilock Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos enforces its own municipal building department and a Protected Tree Ordinance that neighboring Sunnyvale and Mountain View don’t match. Before we excavate a single paver base, grading and demo permits can require certified arborist reports and protective fencing plans - especially on heavily landscaped lots where heritage oaks sit within construction envelopes. That routinely adds 6-10 weeks to project timelines, and our staging plans have to keep excavators and plate compactors outside protected drip lines.
For Unilock owners, this means your paver driveway or patio schedule isn’t just about our crew availability. It’s about arborist coordination, permit sequencing, and hand-tool work near root zones. We’ve learned to build that timeline into our written quotes so you’re not surprised when the start date pushes for tree protection rather than weather. The clay-heavy, foothill-edge soils near Foothill Expressway make the geotechnical report non-negotiable anyway - the arborist review just adds another layer of documentation that out-of-area contractors often miss.
Unilock Models & Products We Service in Los Altos
We work with four core Unilock lines in Los Altos. Brussels Block - the tumbled classic - handles residential driveways well when the base is engineered for clay. Beacon Hill offers a smoother, more contemporary face that pairs with modern teardown-rebuild architecture. Umbriano uses a shot-blast finish with color-matched aggregates; it shows efflorescence less but demands precise joint spacing. Town Hall mimics quarried stone and carries heavier per-unit weight, so the edge restraint system has to be spec’d accordingly.
We stock OEM units and matching accessories locally for fast turnaround on Los Altos repairs. Color batches vary year to year, so we verify current production codes before quoting a patch. For full installations, we source through our regular Los Altos service area suppliers with lead times built into the written schedule.

FAQs - Unilock Construction in Los Altos
Los Altos sits on transitional alluvial and expansive clay soils, particularly near Foothill Expressway, that swell when wet and shrink when dry. A geotechnical report tells us the soil classification, drainage characteristics, and whether we need an engineered base or soil amendment. Without it, standard base depths can fail within two seasons. Call (650) 446-9092 and we’ll coordinate the report as part of our pre-construction scope.
Yes, but the Protected Tree Ordinance requires certified arborist reports and protective fencing plans before grading permits issue. We design staging to keep heavy equipment outside the drip line and use hand tools near critical root zones. The arborist coordination adds 6-10 weeks to pre-construction, which we build into your written timeline. We’ve done this successfully on multiple Los Altos teardown-rebuild lots.
Brussels Block tolerates wet-dry cycling well if the base is engineered properly; its tumbled edges hide minor wear. Umbriano’s shot-blast surface resists efflorescence visually but needs tighter joint maintenance. For driveways with heavy irrigation overspray, we specify a breathable sealer and proper drainage slope away from planting beds. The right choice depends on your specific site conditions, which we assess during the free estimate.
Isolated settled areas or a single spalled run can often be reset with matching OEM units and proper base correction. Once more than roughly a third of the field is failing, full replacement with a geotextile-separated, compacted base saves money over repeated patch cycles. We give an honest repair-vs-replace call based on what we find, not what we’d prefer to sell. Call (650) 446-9092 for a free assessment and written recommendation.
