Unilock Construction in Los Altos Hills, CA | Silver Line Contractors
We provide independent Unilock paver and retaining wall construction across Los Altos Hills, and the one thing that separates our work here is slope. A Unilock driveway or patio in Los Altos Hills is rarely a flat-lot job. It’s a grading, drainage, and retaining wall project that happens to have beautiful pavers on top. That’s the work we do every week. If you’re planning or repairing a Unilock installation in the 94022 hills, call (833) 400-1314 for a free estimate.
We are an independent contractor, not a Unilock authorized dealer or manufacturer affiliate. We install and repair Unilock products because they hold up on hillside sites when the base is done right. We’ve worked with Brussels Block, Beacon Hill, Umbriano, and Olde Quarry on Unilock sales & service projects across the South Bay, and we know which of those lines belong where the grade gets steep.
Why Los Altos Hills Residents Choose Us for Unilock Service
Noel Carvalho, our owner and general contractor, grew up in Gilroy watching his father patch and improve their family home near Christmas Hill Park. That’s where he learned good work either holds or it doesn’t. He studied construction technology at Gavilan College, then spent his twenties and thirties working residential and commercial builds across Santa Clara County before starting Silver Line Contractors. Good construction doesn’t need a sales pitch, the work explains itself.
Los Altos Hills homeowners call us because we price the whole site, not just the paver square footage. A driveway cut into a hillside needs base compaction, drainage, possibly a segmental wall, and driveway access planning before the first Brussels Block goes down. We handle that under one contract. No juggling a paver crew, a grading contractor, and a wall installer. You get one point of contact from the initial site walk to the final joint sanding.
We cover Los Altos Hills service area thoroughly, including every hillside lot in the 94022 ZIP. When you call, we show up knowing the terrain, the town’s hillside review requirements, and what the winter runoff season does to a poorly built base.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Edge spalling and paver shifting on steep driveway aprons. Winter runoff channeling down a slope undermines the bedding sand along the edges, and the dry summer soil movement finishes the job. Pavers start to wander. We reset them over a compacted aggregate base and lock the edges with a proper restraint.
- Efflorescence blooming on Brussels Block after the first wet season. Los Altos Hills gets real winter rain, and when hillside drainage is inadequate, water moves through the paver bed and pulls minerals to the surface. The white haze isn’t a product defect, it’s a drainage symptom. We fix the water path, then clean and re-sand the joints.
- Segmental retaining wall batter and settlement above three feet. Unilock wall systems need geogrid reinforcement and engineered drainage once wall height climbs. We see walls on Los Altos Hills slopes that were stacked without either, and they lean or settle within two or three winters. We rebuild them properly.
- Color fading and joint sand loss on south-facing patios. The dry foothill summer bakes southern exposures. Joint sand fines blow out, and lower-grade sealers break down fast. We re-sand with a polymer-stabilized joint material and recommend pavers like Umbriano for sun-heavy Los Altos Hills patios.
- Washout at the base of long private driveways. Los Altos Hills driveways can run hundreds of feet and cut into slopes. Where the driveway meets the lane or the road, concentrated runoff scours the base. We add drainage swales and erosion control at the transition so the pavers stay put.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Los Altos Hills is a rural-residential town of one-acre-plus lots where nearly every project is a custom hillside build or major remodel requiring grading, retaining walls, and private road work. The town’s own hillside and slope-density review often requires retaining-wall and drainage engineering for driveway cuts before a single paver is laid. What that means for a Unilock paver driveway here is that the job is reviewed as a grading and wall project first. A flat-lot contractor who quotes paver square footage without accounting for cut-and-fill, geogrid reinforcement, and drainage swales will under-price the job and under-build the site. We’ve sat in enough pre-application meetings with Los Altos Hills planning staff to know what gets flagged. Our quotes include the engineering work the hillside review will require, so you don’t get a change order halfway through because the planning department wants a retaining wall detail or a drainage study.
Unilock Models & Products We Service in Los Altos Hills
We install and repair the Unilock lines that perform on hillside sites. Brussels Block for classic driveway and patio surfaces where a tumbled, old-world finish fits the home. Beacon Hill for a more structured, flagstone look on terraced patios. Umbriano for a smooth, contemporary surface that resists fading on sun-exposed Los Altos Hills patios. Olde Quarry for a rugged, quarried texture that handles driveway traffic well. On repairable driveways and walls, we reset pavers and re-sand joints where the base is sound using Unilock’s specified materials or verified equivalents. When the failure is structural rather than cosmetic, we say so plainly and recommend replacement. No overselling scope, no patch jobs on a failed base.

What drives cost in Los Altos Hills more than anywhere flat is site preparation. A hillside driveway with a 20% grade needs more aggregate base, more compaction, more drainage, and often a segmental wall where the cut meets the slope. That’s line-item real cost, not markup. Your free estimate includes a site walk, measurements, and a written scope with line items. No vague allowances that turn into surprises later. Call (833) 400-1314 to schedule yours.

FAQs – Unilock Construction in Los Altos Hills
Yes, when the base and drainage are engineered for the grade. We’ve installed Unilock paver driveways on slopes where a standard flat-lot base would wash out in one wet season. On a long private lane off a slope in the 94022 hills, our crew rebuilt a driveway apron undermined by winter runoff: we reset the Brussels Block over a new compacted aggregate base, added a segmental retaining wall with geogrid and a drainage swale, and re-sanded the joints. The homeowner now has a stable entry that handles the wet season without washout. Call (833) 400-1314 for a free site assessment.
Any Unilock segmental retaining wall can work if it’s built with geogrid reinforcement and engineered drainage once the wall exceeds about three feet. On one-acre-plus Los Altos Hills lots where driveway cuts expose six to eight feet of slope, we engineer the wall as a structural element, not a landscaping feature. The paver or block face is the finish; the geogrid and drain tile behind it are what keep Los Altos Hills from sliding into the driveway. Call (833) 400-1314 with your wall height and we’ll tell you what the engineering looks like.
Efflorescence is mineral deposits pulled to the surface when water moves through the bedding layer. In Los Altos Hills, winter rain on a hillside patio with poor drainage pushes water up through the pavers and leaves the white bloom behind. It’s not a manufacturing defect. The fix is drainage correction, then cleaning and re-sanding. We offer free estimates to diagnose whether your efflorescence is cosmetic or a drainage failure in the making. Call (833) 400-1314.
It can. Los Altos Hills applies slope-density and hillside review standards to driveway cuts and grading on larger lots, and the planning department may require retaining-wall details, drainage studies, or erosion control plans before you’re approved to pull a permit. We prepare those documents as part of the estimate so review doesn’t stall the job later. The timeline extension is real, but it’s manageable when the paperwork is right the first time. Call (833) 400-1314 and we’ll walk you through what your specific project triggers.
On shared private lanes in Los Altos Hills, neighbors often split driveway apron and access road costs by frontage or usage agreement. We’ve coordinated those arrangements before. The key is a written scope that separates shared-lane work from your individual driveway so each party knows their share. We’ll prepare that breakdown as part of the free estimate. Call (833) 400-1314 to schedule a site walk.
