Unilock Construction in Mount Hermon, CA | Gold Star Contractors
If you’re planning a Unilock paver driveway, patio, or retaining wall in Mount Hermon, the real question isn’t whether the pavers will look good. It’s whether the base under them will survive redwood roots, winter runoff, and a fog line that keeps everything damp for months. We’re Gold Star Contractors, and we install Unilock pavers and walls across Mount Hermon with base designs that respect both the tree preservation rules and the fire-clearance codes that govern this community. Call (833) 382-8544 for a free estimate, and we’ll walk your lot before we quote anything.
We’re an independent Unilock service provider. That means we’re not manufacturer-affiliated or authorized by Unilock, but we work with their products daily and know which profiles hold up under redwood shade versus which ones turn slick with moss by February.
Why Mount Hermon Residents Choose Us for Unilock Service
Most paving crews in the Santa Cruz Mountains treat a redwood lot like any other job site. We don’t, because Mount Hermon won’t let you. The critical root zones around protected old-growth redwoods dictate how deep you can excavate, where your edge restraints can sit, and whether a standard paver base will even work. Noel Carranza, our owner and Mount Hermon General Contractor, studied construction technology at Fullerton College and spent years on Orange County jobs before building his own operation. He’s the kind of contractor who reads the tree report before he orders the base rock.
We carry Unilock’s own wall components and jointing materials because mixing brands at a wall or step joint is where failures start. When an existing concrete base is sound, we repair and re-lay rather than tear out. And when a re-lay won’t fix a failed sub-base, we tell you that upfront instead of selling you a patch job that heaves again next winter. One call, done right. That’s the only way we know how to run a job.

Common Unilock Construction Problems We Solve in Mount Hermon
Mount Hermon’s damp, shaded lots create a specific set of failures in Unilock installations. Here’s what we see most:
- Moss and algae on tight-joint pavers. Brussels Block and other close-set profiles trap moisture in the redwood shade. We see entire patios turn green-slick by late winter, and the fix is usually a re-graded base plus a jointing material that drains instead of holding water.
- Sub-base washout on steep lots. Heavy winter rain and uphill drainage push bedding sand right out from under pavers on Mount Hermon’s hillside parcels. The pavers look fine until they start sinking, and by then the base is gone.
- Efflorescence and staining from slow-drying shade. Pavers that never fully dry develop that white chalky bloom. It’s cosmetic until it isn’t, and in Mount Hermon it’s almost guaranteed without proper base drainage.
- Edge and joint displacement near root zones. When a wall or walk abuts a protected redwood root zone, you can’t dig full depth for the edge restraint. Roots lift, joints open, and the whole edge walks downhill over a season or two.
- Heaving at transitions. On lots where a paver walk meets a deck or cottage foundation, differential settling from saturated ground shows up as a lip or gap within the first wet season.
Unilock Service in Mount Hermon: What Local Conditions Mean for Your Equipment
Mount Hermon’s conference grounds sit under protected old-growth redwoods. That means a paver driveway or patio here often can’t be excavated to full depth inside the critical root zone, and the base has to be designed around arborist-set limits that would never apply on a normal suburban lot. We’ve handled this on lots along Conference Drive and elsewhere in the community. What changes is the base section itself: thinner excavation, permeable open-graded stone instead of compacted sand, and edge restraints set shallow enough to avoid cutting roots that the county and Cal Fire both care about. You can’t just dig deeper to fix a drainage problem here, because the tree report won’t let you. So the base has to work harder with less depth, and that’s a design problem most crews never learn to solve.
On a steep retreat-cottage lot off Conference Drive, our crew rebuilt a Brussels Block walk that had heaved where winter runoff and redwood roots met the old edge restraint. We re-graded the base, switched to a permeable open-graded profile and reset the Unilock edge, and the walk now drains instead of holding water against the root zone.
Unilock Models & Products We Service in Mount Hermon
We work with the full Unilock hardscape catalog, including the lines that actually hold up in Mount Hermon’s conditions. Brussels Block is a common choice for driveways and walks, though its tighter joints need real drainage design here. Beacon Hill and Senecal give you more texture and wider joints that shed water better. Town Hall is a favorite for retaining walls and steps where the visual weight matters. Our parts approach is simple: Unilock wall components and Unilock jointing materials, no brand mixing at structural joints. We keep common profiles and edge units in local inventory so a Mount Hermon repair doesn’t wait on a freight shipment from the Midwest.

FAQs – Unilock Construction in Mount Hermon
Yes, in most cases. We design the base around the critical root zone rather than excavating through it, using a shallower profile with open-graded stone and edge restraints set above the roots. An arborist report defines the limits, and we build inside them. Call (833) 382-8544 if you’ve been told your lot can’t take a paver driveway. It often can, just not the way a standard crew would build it.
Some will, especially tighter-joint profiles like Brussels Block in full shade. We specify jointing materials and base drainage that keep water moving out from under the pavers, which is the single biggest factor in whether moss takes hold. A properly graded base makes a bigger difference than the paver surface itself.
Yes, and that conflict is real in Mount Hermon. Cal Fire wants defensible space cleared, while county tree ordinances protect the redwood root zones. We site paver areas and walls so they satisfy the fire-clearance requirements without excavating into protected roots, and we coordinate with the arborist so one report covers both sets of rules.
First we find out why it shifted, which on these lots is usually water moving through the base or root pressure under the edge. We rebuild the base with proper drainage, reset the Unilock edge with the right restraint, and re-lay the wall or step. If the base under it has fully failed, we’ll tell you that a patch won’t hold and quote the rebuild honestly. Call (833) 382-8544 for a repair assessment.
A paver driveway runs $7,000 to $18,000, a paver patio $3,500 to $11,000, and a concrete driveway $4,500 to $12,000, with driveway sealing between $250 and $700. Your actual number depends on slope, root-zone constraints, and drainage work. Estimates are free. Call (833) 382-8544 and we’ll give you a written quote specific to your lot.
