Unilock Construction in Los Altos Hills, CA | San Bernardino Contractors
Unilock paver driveways, patios, and retaining walls in Los Altos Hills run $3,500 to $18,000 depending on scope, slope, and site access. We’re San Bernardino Contractors, an independent Unilock service provider, not a manufacturer affiliate. What separates our Unilock work here is that we understand how Los Altos Hills’ private lanes, hillside slopes, and fire-defensible-space rules change the way pavers actually get specified and installed. If you’re planning a paver project in 94022, call (855) 473-5620 for a free estimate. You can also review our Unilock sales & service page for the full range of what we handle.
Why Los Altos Hills Residents Choose Us for Unilock Service
Ruben Castillo, owner of San Bernardino Contractors, grew up watching his uncle reroof houses and frame garages on a shoestring budget. That hands-on training taught him something that still drives how we work: if it’s not built right the first time, you’re just paying for it twice. He went through construction technology training at San Bernardino Valley College, where he learned to read plans and understand load paths before anything else. Since then, we’ve installed Unilock pavers and walls on steep, wooded Los Altos Hills lots for years as a Los Altos Hills General Contractor, learning how their systems perform under wildfire-defensible construction and clay-soil drainage demands. Our crews work with the town’s Hillside Ordinance and private-road quirks every week, so we specify Unilock products that meet both design intent and the site constraints unique to this town. We carry OEM Unilock edge restraints and polymeric sands, and we’re an independent service provider, which means we answer to you, not to Unilock’s corporate office.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Efflorescence on Brussels Block pavers. Winter rains hit clay soils hard in Los Altos Hills, and poor drainage traps moisture beneath the paver surface. Salts migrate upward and leave chalky white deposits on Brussels Block and other concrete pavers. We clean the surface, fix the drainage, and seal or maintain as needed.
- UV fading and color inconsistency. Freeze-thaw cycles are rare here, but the intense sun in Los Altos Hills and wildfire-defensible-space clearing mean pavers sit fully exposed. Unilock’s standard concrete pavers can fade unevenly when not sealed. We install with UV-stable sealants and recommend a maintenance cycle that holds color longer.
- Paver shifting and rutting on sloped driveways. Improper base compaction on steep private lanes lets water runoff concentrate and undercut the base. We see this most on driveways where the subgrade wasn’t proof-rolled before the geotextile and base layers went in. The fix is removal, recompaction, and a proper base rebuild.
- Edge failure where pavers meet drainage swales. Ember-resistant vent and roof requirements often mean paver installations must integrate with noncombustible edging and drainage swales. When these details get skipped, edges wash out and the system fails outward. We install Unilock edge restraints and tie them into the swale geometry correctly.
- Cracked or settled wall units on hillside lots. Tandem Wall and U-Cara retaining walls on steep Los Altos Hills slopes are only as good as the base course and drainage behind them. When wall units crack or settle, it’s almost always a base or backfill problem, not a product defect. We repair if the base is sound; if structural movement exists, we recommend replacement honestly.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Los Altos Hills is a town where private lanes often can’t support concrete trucks or full-size delivery vehicles. That’s true even in well-known areas like the narrow roadways off La Barranca Road. What it means for Unilock repair in Los Altos and surrounding areas is specific: paver deliveries must be staged on neighboring parcels with permission, or transferred to smaller trucks and moved by conveyor up to the project. This adds coordination time to every driveway or patio project here. It also changes how we plan base prep. On a steep lane, you can’t just dump aggregate and spread. You pump it, you move it in stages, and you compact carefully between lifts so the finished surface holds up under winter runoff on clay soil. Contractors who don’t work in Los Altos Hills don’t plan for this until it’s too late and a delivery truck is blocking someone’s private lane. We plan for it before the first pallet leaves the yard.
One job stands out. A homeowner on a narrow private lane off La Barranca Road needed a new Unilock Brussels Block driveway, but the lane couldn’t handle a full-size delivery truck. We staged pallets on a neighbor’s approved pad and used a compact conveyor to move materials up the slope, then installed the pavers over a geotextile-separated base with Unilock edge restraints to handle winter runoff. The finished drive met fire-defensible-space clearance and has stayed stable through two rainy seasons.
Unilock Models & Products We Service in Los Altos Hills
We work with Unilock’s core product lines: Brussels Block, Beacon Hill, Tandem Wall, and U-Cara. Brussels Block is the most common driveway and patio paver we install in Los Altos Hills because its tumbled edges work well with the town’s estate-lot aesthetics. Beacon Hill is a larger-format paver that reads more modern and handles heavy vehicle loads. Tandem Wall and U-Cara are for retaining walls and vertical features on sloped lots. For parts, we use Unilock’s OEM edge restraints, polymeric sands, and wall adhesives to maintain system integrity. For standard base materials and geotextiles, we source equivalent-quality aftermarket products to manage costs without cutting corners on performance. When a paver or wall unit is cracked or settled, we repair if the base is sound. If there’s widespread efflorescence or structural movement, replacement is the honest recommendation.

FAQs – Unilock Construction in Los Altos Hills
Can Unilock pavers be used on steep driveways in Los Altos Hills?
Yes. Unilock pavers work on steep driveways when the base is properly compacted and drainage is controlled. We use geotextile separation, proper aggregate depth, and Unilock edge restraints to prevent shifting on sloped lots. Call (855) 473-5620 to discuss your specific grade and get a free estimate.
How do I prevent efflorescence on my Unilock Brussels Block pavers in Los Altos Hills?
The first step is fixing the drainage that lets moisture sit beneath the pavers on clay soil. Then clean the surface properly and seal with a UV-stable sealant. On Los Altos Hills lots with poor drainage, we recommend checking the base and edge restraints before treating the surface. Call us for an evaluation.
What Unilock products meet wildfire-defensible-space requirements for Los Altos Hills?
Concrete pavers like Brussels Block and Beacon Hill are inherently noncombustible and meet many fire-defensible-surface requirements when installed over proper base material. The key is integrating them with noncombustible edging and drainage swales that support the town’s wildfire rules. We specify the full system, not just the paver on top.
How does the private road network in Los Altos Hills affect Unilock paver installation?
Private lanes often can’t support concrete or full-size delivery trucks, so we stage materials on neighboring parcels with approval or transfer to smaller vehicles and move material by conveyor. This adds coordination time but prevents road damage and project delays. We handle the logistics so you don’t have to.
What’s the typical cost to replace a paver driveway with Unilock in Los Altos Hills?
Most Unilock driveway replacements in Los Altos Hills run between $7,000 and $18,000 depending on square footage, slope, and access conditions. Paver driveway installation and full driveway replacement are priced per the site specifics. Call (855) 473-5620 for a free line-item quote on your exact property.
