Unilock Construction in Lexington Hills, CA | San Mateo Construction
We provide independent Unilock installation and repair across Lexington Hills, from Brussels Block driveways to Olde Quarry retaining walls. The one thing that makes our work here different: every paver and wall plan has to clear Santa Clara County’s wildfire defensible-space and septic-expansion review, not just look right. If you’re planning a Unilock driveway, patio, or wall in Lexington Hills, call (855) 901-7266 for a free estimate. Noel Carrington and our crew at San Mateo Construction can walk your lot before you commit to anything.
Why Lexington Hills Residents Choose Us for Unilock Service
We’re independent Unilock installers, not a manufacturer sales arm. That means when we look at a paver driveway or retaining wall in Lexington Hills, we’re looking at how it holds up to the actual grade, the actual runoff, and the actual county requirements, not trying to move a product line. We’ve been installing and repairing Unilock hardscape systems across the Santa Cruz Mountains, from Los Gatos Unilock service calls to Lexington Hills jobs, long enough to know which failure patterns repeat on steep, wooded lots and which details actually prevent them. Noel grew up pouring concrete footings with his father near Coyote Point, studied construction technology at Skyline College, and has spent the better part of three decades running residential and light commercial jobs across San Mateo County. That background matters when a Lexington Hills site plan gets kicked back over the 100-foot defensible-space zone or a retaining wall needs geogrid spec’d for saturated soil. If you’re comparing contractors, ask each one how they’d handle a paver driveway that has to stay clear of both a septic expansion area and a fire-clearance review. See who gives you a straight answer.

Common Unilock Construction Problems We Solve in Lexington Hills
Here’s what we see most often on Unilock projects in Lexington Hills, and what actually causes it:
- Paver migration and heave on steep driveways. When a hillside runoff channel or the weight of a delivery truck pushes Unilock pavers downhill, it’s almost always because the base wasn’t pinned to grade. We re-set the base, install edge restraint anchored into the slope, and re-lay the pavers so they stay put through the next wet season.
- Polymeric sand washout after severe winter storms. Lexington Hills storms drop heavy rain on slopes that need a swale or surface drain above the patio or driveway. Without one, water sheets across the surface and carries the joint sand out. We fix the drainage first, then re-sand the joints so the repair actually lasts.
- Retaining wall face rotation and bulging. Where drainage aggregate or geogrid was omitted or undersized, saturated soil pushes the wall face out. Patching the face won’t hold. We rebuild the wall section with proper drainage stone and geogrid, then re-set the Unilock wall blocks.
- Flagstone and paver joint spalling and faded color. Hot, dry summers plus debris and ash from wildfire-season exposure take a toll on Unilock surfaces in Lexington Hills. We color-match replacement pavers and re-sand joints, and we can advise on sealers that hold up better to ash exposure than what most homeowners pick off the shelf.
- Base washout under existing paver surfaces. On steep Lexington Hills lots, a saturated slope above a patio or driveway can undermine the base even if the surface looks fine. We find the water path, install drainage at the top of the slope, and re-compact the base before re-laying the Unilock pavers.
Unilock Service in Lexington Hills: What Local Conditions Mean for Your Equipment
Lexington Hills sits in an unincorporated high-fire-severity zone, and that one fact shapes a Unilock project here more than any design preference. A hardscape plan has to leave a documented 100-foot defensible-space clearance and keep pavers clear of the septic system’s approved expansion area, or county plan review simply stalls. That fire and septic bookkeeping is as much a part of a Unilock driveway or patio build here as the base prep. On a steep, wooded lot off Old Santa Cruz Highway, our crew rebuilt a failing Brussels Block paver driveway whose base had washed out from hillside runoff after a winter storm, similar to Unilock service in Monte Sereno we handle on comparable terrain. Because the narrow private road couldn’t take a full concrete truck, we used pump-truck and smaller-mix deliveries, re-graded the slope with a drainage swale and geogrid, and re-laid the Unilock pavers with edge restraint pinned into the slope so the surface stays put through the next wet season. A flat-lot contractor who’s never worked Lexington Hills terrain won’t anticipate those constraints until they’re mid-project. We plan for them from the first site visit because we’ve seen what happens when you don’t.
If you’re considering Unilock work on a steep Lexington Hills lot, our Unilock sales & service page covers our approach to paver systems, retaining walls, and OEM part sourcing in more detail. For a broader look at where we work across the region, see our Lexington Hills service area page.
Unilock Models & Products We Service in Lexington Hills
We install and repair the Unilock product lines that hold up best on Santa Cruz Mountains terrain: Brussels Block for driveways and walkways, Cambridge Pavingstones in both round and square formats, Beacon Hill Flagstone for natural-stone-look patios, and Olde Quarry retaining wall blocks for sloped lots that need real structural support. For repairs, we source genuine Unilock pavers and wall blocks so the color match holds, then pair them with quality aftermarket base aggregate, geogrid, and polymeric sand where those materials perform as well or better on steep terrain, whether it’s Unilock repair in Cambrian Park or right here in Lexington Hills. Honest stance: we’ll swap isolated cracked or settled pavers and re-set the base every time. If a wall is bulging or a driveway base is failing across the width, patching isn’t the responsible call, and we’ll tell you that plainly.

FAQs – Unilock Construction in Lexington Hills
No. San Mateo Construction is an independent Unilock service provider. We install and repair genuine Unilock pavers and wall blocks, but we’re not manufacturer-affiliated or authorized. That independence is useful: we recommend the Unilock product that actually fits your terrain and budget, not the one a distributor wants to move.
In Lexington Hills, it’s almost always drainage. Steep slopes above a patio or driveway send water across the surface faster than the sand can hold, especially when there’s no swale or surface drain above the hardscape. We fix the drainage path first, then re-sand the joints. Call (855) 901-7266 for an exact quote, estimates are free.
It depends on whether we’re repairing a section or rebuilding a base. An isolated paver swap on a patio can take a single day. A driveway base rebuild on a steep slope with drainage work runs longer, especially if county plan review adds fire-clearance or septic-clearance documentation time.
We service Brussels Block, Cambridge Pavingstones (round and square), Beacon Hill Flagstone, and Olde Quarry retaining wall blocks. For every line, we source genuine Unilock product for color-matched repairs and pair it with quality aftermarket base, geogrid, and polymeric sand where those outperform on steep terrain.
If the site reveals something we couldn’t see before excavation, like a hidden septic line or a saturated base layer, we’ll flag it, show you what’s there, and price the change before any additional work starts. Call (855) 901-7266 for a free estimate, and we’ll walk the lot together first so there are fewer surprises.
