Garden Grove Contractors is not manufacturer-affiliated or authorized by Unilock. We’re an independent general contractor who specifies Unilock products because they hold up on high-end residential projects here, and we stand behind the work independently. From the countertop to the roofline, one contractor, one contract.

Why Los Altos Residents Choose Us for Unilock Service

Owners in Los Altos don’t tolerate crews that read the product manual on site. We’ve been specifying Unilock Brussels Block, Beacon Hill, Town Hall, and Thornbury on Bay Area projects for years, and we know how each line behaves under real loads and real clay. That familiarity means we don’t guess at base depth or jointing detail. We spec what the soil and the tree canopy demand.

Noel Cardenas, our owner, grew up around concrete and has spent years on structural and exterior builds across California. He’s the one who walks each Los Altos lot before we write a scope, because what’s under the pavers matters more than what’s on top, whether it’s here or for Loyola Unilock service. We’re a full-scope general contractor, which means the same crew that handles your Unilock driveway can also manage the fencing, siding, or ADU going in next to it. That’s single-source accountability, not five phone calls.

Common Unilock Construction Problems We Solve in Los Altos

• Edge restraint lift and joint sand loss on driveways. Los Altos sits on expansive clay that swells during winter rains. If the original base was shallow, the clay heaves and the edge restraints lift. We remove the affected sections, re-compact with proper aggregate, and re-set restraints before re-sanding the joints.
• Pavement settlement and lippage at garage aprons. Many 1950s and 1960s ranch homes here had minimal base depth under their original concrete, and when owners convert to Unilock pavers without addressing the base, the apron settles. We see this consistently on lots near the Los Altos Golf & Country Club. Repair means re-grading and re-compacting, not just wiggling pavers back into place.
• Efflorescence and staining on lighter-colored pavers. Repeated wet-dry cycles and irrigation overspray pull salts to the surface, especially on Beacon Hill and Town Hall in lighter tones. We clean with appropriate efflorescence removers and adjust drainage or irrigation direction so it doesn’t return in a season.
• Joint sand erosion and weed intrusion along root-protected zones. Where Los Altos requires root protection fencing, excavation is limited and drainage can be compromised. Joint sand washes out faster. We address this with polymer-modified jointing sand and permeable designs that keep water moving away from roots.
• Widespread base failure that looks like “just a few sunken pavers.” When you see lippage across a large area, the base has failed. Patching it is throwing money at the symptom. We’ll tell you when full replacement is the honest fix, and we’ll show you why before you spend a dollar.

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

Los Altos has some of the most stringent heritage-tree ordinances in the Bay Area. Removing a mature oak or redwood often requires a city permit and an arborist report, and construction crews must fence and root-protect trees before demolition even begins. That ordinance changes how a Unilock paver project gets engineered here, and it’s a distinction a generic paver contractor from outside the area will miss.

Here’s what it means on the ground. On a ranch-era lot near the Los Altos Golf & Country Club, a homeowner wanted a Unilock Brussels Block driveway, but a mature valley oak within the setback required city-approved root protection. We re-engineered the base to a shallower profile with a geogrid-reinforced section and installed a permeable joint system to keep water off the root zone. The finished drive has handled two winters without settlement. That’s not a detail you’ll find on a product page. It’s what happens when you actually build in Los Altos.

Unilock Models & Products We Service in Los Altos

We install and repair Unilock sales & service across the full residential range: Brussels Block, Beacon Hill, Town Hall, and Thornbury. For repairs, we use Unilock’s own edge restraints, joint sand, and compatible components where they matter for performance. For base materials and geotextiles, we source quality aftermarket product to manage cost without cutting corners. That’s the right split: OEM where failure is expensive, aftermarket where the spec is straightforward.

We will repair localized settlement or sand loss when the base is sound. When widespread lippage or base failure is present, we recommend full replacement. We’d rather tell you the truth and do the job once.

FAQs – Unilock Construction in Los Altos

Can we install a Unilock paver driveway if a heritage oak is close to the driveway? Yes, and we do it regularly in Los Altos. The city often requires root-protection fencing and an arborist report before any excavation. We work within those rules, sometimes redesigning the base to a shallower profile with geogrid reinforcement and permeable joints so water doesn’t pool on the root zone. Call (877) 373-9230 for a lot-specific answer.

How do Unilock pavers handle Los Altos’s expansive clay soils? The pavers themselves are fine. The base is what fails if it was built shallow or under-compacted. Los Altos clay swells in winter and shrinks in summer. We spec base depth, geotextile, and edge restraints for that movement, which is why our paver driveways don’t develop the lippage we see on underbuilt ones.

What’s the best Unilock paver for a Los Altos driveway that sees both cars and winter rain? Brussels Block handles vehicular loads well and has a classic look that suits ranch-era Los Altos homes. Beacon Hill and Town Hall are also strong options. The paver matters, but the base and edge restraint matter more. We’ll recommend the right combination for your lot, not the easiest one to lay.

Do you repair efflorescence on Unilock pavers or does the whole patio need replacing? Efflorescence is a surface condition, not a structural failure. We clean it with appropriate removers and fix the drainage or irrigation issue causing it. The patio only needs replacing if the base has failed underneath. We’ll tell you which one you’re dealing with, and we’ll show you the evidence.

How does Los Altos’s neighbor-notification rule affect a Unilock paver project? Some construction in Los Altos requires notifying neighbors before work begins, especially when it involves significant excavation or changes to drainage. For a standard paver patio or driveway, it’s usually straightforward, but we handle the paperwork so you don’t get a stop-work notice. Call (877) 373-9230 to get an exact read on your street.
