Why Los Altos Residents Choose Us for Unilock Service

We know the difference between a paver job that looks good for one season and one that stays flat for two decades. Ruben Castillo, our owner, learned construction the hard way: weekends as a kid watching his uncle reroof houses and frame garages on minimal budgets, then formal construction technology training at San Bernardino Valley College. That background means we read load paths, understand base compaction, and don’t cut corners on anything structural. For Unilock work specifically, we excavate deeper than the minimum, compact in lifts, and set edge restraint that actually holds. Los Altos homeowners call us because we talk materials fluently, name the exact Unilock line we’d spec, and explain why a correction is needed before we ever start swinging shovels.

Common Unilock Construction Problems We Solve in Los Altos

• Base settlement over expansive clay. Los Altos sits on clay soils that swell with winter rain and shrink through dry summers. Pavers laid on under-compacted base go out of plane within a season or two. We over-excavate, re-compact in lifts, and install a proper aggregate base before any Unilock unit touches the ground.
• Joint sand washout on sloped driveways. Many 1940s and 1960s ranch lots in 94022 and 94024 have driveway aprons that shed water straight toward the garage. Sheet flow scours polymeric sand and lets Brussels Block units creep. We address drainage slope first, then lock joints with fresh sand.
• Efflorescence blooms after the wet season. October through April rains leave a white mineral haze on Copthorne and Brussels Block surfaces, especially where pavers were sealed before the base fully dried or the base drains poorly. We correct the drainage, clean the surface, and reseal only when conditions allow.
• Chipped corners on Town Hall units. Root-lifted sections and rocking pavers take impact from tires and mower decks, spalling faces and corners. We lift the affected area, correct the base, and reset with matching Unilock units so the repair disappears into the field.
• Edge creep on driveway borders. Without solid edge restraint, the outer rows of a paver driveway migrate outward under vehicle loads. We reset boundaries with proper restraint and re-compact the perimeter so the pattern stays tight.

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

Los Altos runs a discretionary design-review system where neighbors and the Planning Commission weigh in on front-yard changes. A paver driveway or entry patio here isn’t just a construction project; it’s a public approval process. On a Brussels Block driveway replacement off a 94024 ranch lot, our crew found the original apron laid directly on native clay with no over-excavation. The pavers had heaved, joints drained toward the garage, and the surface looked rough. We lifted the field, dug out the clay, re-compacted a proper base, reset the units on fresh edge restraint, and re-sanded. The driveway now sheds water away from the door instead of into it. That’s the kind of fix Los Altos demands: invisible craftsmanship that matches the ranch-house streetscape while actually functioning for decades. Our Unilock selections and shop drawings are prepared to survive design review, not just the building department. Color, unit scale, and edge detail must read as compatible with surrounding homes, and we spec accordingly.

Unilock Models & Products We Service in Los Altos

We install and repair the Unilock lines most common across Los Altos driveways and patios: Brussels Block, Beacon Hill Flagstone, Copthorne, and Town Hall. When repairs are needed, we source genuine Unilock units and matching edge restraints so the replacement blends with the existing field. We don’t substitute off-brand pavers or use cheap joint sand. Because clay movement is the underlying issue in most Los Altos paver failures, we’ll tell you plainly if a spot repair makes sense or if a lift-and-rebase is the smarter spend. Chasing joints every spring costs more over five years than fixing the base once. We stock compactable base material and polymeric sand locally for fast turnaround across Los Altos, and we also provide Unilock service in Mountain View.
