Unilock Construction in Los Altos Hills, CA | Toolbox Contractors
We install and repair Unilock paver driveways, patios, and retaining walls across Los Altos Hills, including Brussels Block, Beacon Hill Flagstone, and U-Cara systems. What makes our Unilock work different here is simple: hillside drainage, county permitting, and private-lane access shape every project, and we plan for all three before the first paver goes down. If you’re dealing with a failing Unilock driveway or planning new hardscape, call (855) 382-3257 for a free estimate.
Toolbox Contractors is an independent contractor. We are not authorized, sponsored, or endorsed by Unilock. We specify, install, and repair their products because they hold up on sloped, clay-heavy lots when the base and drainage are done right, and we stand behind our own workmanship on every job.
Why Los Altos Hills Residents Choose Us for Unilock Service
Norm Castellano grew up around half-finished houses and learned early that the difference between a paver job that lasts fifteen years and one that fails in three comes down to what’s underneath. His crew at Toolbox Contractors brings that same instinct to every Unilock project in Los Altos Hills. We’ve torn out enough failed paver fields on these hillsides to know exactly where water travels, how clay expands when saturated, and what a private lane does to a driveway base over five winters.
We’re general contractors first, which means when your Unilock driveway needs a drainage plan, a retaining wall rebuilt, or new noncombustible edging tied into a defensible-space design, we handle it as one scope. No coordinating three specialists. One contractor, every phase. Call our Los Altos Hills service area team at (855) 382-3257 to talk through what you’ve got.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Efflorescence and salt bloom on Brussels Block and Beacon Hill pavers. Winter runoff from uphill lots keeps the sub-base saturated for weeks at a time, and those minerals wick up through the paver surface as white bloom. We clean it, diagnose whether the base drains properly, and fix the drainage so it doesn’t return every rainy season.
- Base failure and rutting on private-lane driveways. Many Unilock driveways in Los Altos Hills were laid over a base that was never built for the grade change from a winding road onto the property. We see this all the time – pavers sinking into ruts within a few seasons. The fix is pulling the field, re-grading, and rebuilding the base with proper drainage aggregate.
- Retaining-wall batter and joint separation on Estate Wall and U-Cara systems. Saturated clay pushes hard against walls that were built without drainage aggregate and weep paths. Walls start leaning, joints open up, and caps pop off. We rebuild with the drainage the wall should have had from day one.
- Paver heave and lippage from seasonal creek and canyon drainage. Los Altos Hills has seasonal creeks and canyon drainage paths that re-route water under paver fields during heavy rain years. Pavers lift, shift, and create trip hazards. We correct the drainage path and re-lay the field so water stops moving through it.
- Noncombustible edging and wall material requirements. Much of Los Altos Hills sits in a very high fire hazard severity zone, which means hardscape edging, wall caps, and adjacent materials need to meet fire-resistant standards. We specify accordingly on every project.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Los Altos Hills is unincorporated, and permits run through Santa Clara County rather than a city building department. That fact alone changes how Unilock construction works here. On a flat suburban lot in a neighboring city, a paver driveway is mostly about excavation, base, and pavers. In Los Altos Hills, a driveway or patio on a private lane routinely requires a grading permit and a drainage plan before hardscape can begin. The county wants to see where water goes, how the grade changes, and how the work affects the lane’s drainage path. We’ve done enough of these to know the sequence: engineer the drainage, pull the permit, coordinate construction traffic with neighbors on the narrow lane, then build. The town’s one-acre-plus lots and hillside-ridgeline limits also mean your Unilock patio or driveway is usually part of a larger site plan, not a standalone project. We treat it that way. Tell me what you’ve got and I’ll tell you what it actually needs.
Unilock Models & Products We Service in Los Altos Hills
We work with the full range of Unilock hardscape products common on Peninsula hillside estates. Brussels Block pavers show up on driveways and walkways throughout the town. Beacon Hill Flagstone is a frequent choice for pool decks and patios. Estate Wall and Pisa2 handle retaining walls on sloped lots, and U-Cara is what we see on pillars and seat walls where owners want a more finished face. When repairs call for matching units, we source genuine Unilock pavers, edge restraints, anchoring adhesives, and cap units so the repair blends with the existing field. We don’t cut corners with off-brand substitutes that look close but weather differently. Check our Unilock sales & service page for the full scope of what we handle.

What moves the number on a Los Altos Hills job is site access, grade change, drainage scope, and whether the county requires a grading permit. A flat driveway replacement on a level lane stays toward the lower end. A hillside driveway with an underdrain, retaining edge, and construction-traffic coordination lands higher. Our estimates are free, written, and line-itemed. Call (855) 382-3257 to get an exact number for your property.

FAQs – Unilock Construction in Los Altos Hills
Most Unilock driveway replacements in Los Altos Hills take five to ten working days from demolition to final compaction, depending on the size of the field and whether drainage work runs underneath it. If the county requires a grading permit, add one to three weeks for the permit review before we start. Call (855) 382-3257 for a timeline based on your specific lot.
