Unilock Construction in Mount Hermon, CA | Milpitas Construction
We install and repair Unilock paver patios, driveways, and retaining walls across Mount Hermon as your trusted Mount Hermon General Contractor, and the thing that separates our work here from anywhere else is simple: we build around redwood roots, not through them. Most Unilock contractors in the Bay Area never deal with protected root-zone ordinances or the kind of canopy moisture Mount Hermon gets every single winter. If you’re planning a paver project and want a crew that’s already navigated arborist sign-offs and hand-dug excavations in this exact community, call (877) 752-4194 for a free estimate.
Why Mount Hermon Residents Choose Us for Unilock Service
We’re an independent Unilock hardscape installer, not a dealer and not a manufacturer-authorized shop. That distinction matters. It means we’re free to tell you what actually holds up under Mount Hermon’s redwood canopy instead of what a brochure says should work. We’ve laid Brussels Block, Brussel Dimensionals, Beacon Hill, and Bristol Valley units across the Santa Cruz Mountains for years, and we have a running mental file of what fails and what doesn’t in this specific microclimate.
Ken Stafford, our owner, grew up around Milpitas and came up through construction technology at Evergreen Valley College before spending two-plus decades managing ground-up builds and remodels across the Bay Area. He’s the one who insists we spec materials by name so you know exactly what’s going into your home. His dad was a finish carpenter who kept a tidy garage and an even tidier conscience, and that’s where our thing about doing work you’re not embarrassed to stand behind comes from. Build it right the first time – the Bay Area doesn’t give you a free pass on shortcuts.

Common Unilock Construction Problems We Solve in Mount Hermon
- Redwood needle tannin staining on light-colored pavers. Mount Hermon’s constant needle drop discolors pale Unilock units faster than almost any other local factor. We clean, re-seal, and when the stain is too deep, we’ll re-lay just the affected field rather than rip out the whole patio.
- Moss and mildew in open paver joints. Fog drip and shade create persistent dampness that feeds organic growth in joint sand. We re-sand with polymeric sand sized for wet canopy and, where it helps, slightly tighten the joint layout so debris has fewer places to collect.
- Redwood root heave racking paver fields out of plane. Shallow-rooted redwoods push upward under steep lots, opening joints and loosening edge restraints. We see this constantly on hillside patios here, and the fix starts with careful hand-digging, not a machine that chews through roots.
- Subsurface drainage failures on slope-post patios. When drainage isn’t addressed before the base goes in, water moves through the aggregate and settles the bedding course into ruts. Mount Hermon’s wet winters make this a six-month-a-year problem if the base was ever cut short.
- Wildfire-defensible conflicts with older hardscape edges. Wood-edged beds and combustible landscape walls against Unilock patios violate modern WUI ember-resistant standards. Many older installs in Mount Hermon lack the detailing, and we retrofit the edge so the hardscape doesn’t become a fire path.
Unilock Service in Mount Hermon: What Local Conditions Mean for Your Equipment
Here’s the thing most hardscape crews don’t understand until they’ve worked here: Mount Hermon’s steep, redwood-shaded lots mean Unilock paver work is governed less by the paver than by root-zone ordinances and arborist oversight. Excavation for base and edge restraint often has to be hand-dug around protected redwood roots, which simply isn’t the case on the open lots down in Felton or Scotts Valley. On a steep wooded lot off Conference Drive, we rebuilt a settled Brussels Block patio where root heave and trapped needle litter had racked the field out of plane and left moss-filled joints. We hand-dug around the protected roots with arborist sign-off, re-based and re-compacted the bedding course, reset the edge restraint, and re-sanded with polymeric joint sand sized for the damp canopy. The patio now drains and sits flat through the wet season. That’s the kind of project you can’t bid from a satellite photo – you have to know what you’re walking into under the canopy.
Unilock Models & Products We Service in Mount Hermon
We work on the full range of Unilock systems people actually use in Mount Hermon: Brussels Block for tumbled patios, Brussel Dimensionals for interlocking and permeable applications, Beacon Hill for retaining walls, and Bristol Valley for plank-style permeable walks. We source genuine Unilock units and manufacturer-matched edge restraint, geogrid, and polymeric joint sand so the system stays compatible. Where a wall or patio is only locally settled, we lift, re-base, and re-lay rather than tear out the whole field – and we’ll tell you honestly when the base failure is too deep to patch.

FAQs – Unilock Construction in Mount Hermon
Yes, and faster than on any open-sun lot. The combination of fog drip, heavy shade, and constant needle litter makes organic growth in paver joints a near certainty within a season or two. The fix is re-sanding with a polymeric joint sand rated for wet conditions and, where the layout allows, slightly tightening the joints so debris has fewer places to collect. Call (877) 752-4194 if your patio’s gone green – we can re-sand and re-seal it.
Yes, and it’s a specialty of ours. The trick is hand-digging around the protected root zone with arborist oversight, then over-excavating less and compensating with a properly compacted crushed rock base that still allows for drainage. It’s slower and more expensive than a standard install, but it’s the only way to avoid killing trees or settling the patio out of plane. Call (877) 752-4194 and we’ll walk your slope with you before you commit to anything.
They need a deeper, better-draining base and much more attention to root barriers. Ben Lomond and Scotts Valley get sun and have open, gently sloped lots; Mount Hermon brings canopy moisture, steep terrain, and redwood roots that will heave a driveway in a few wet seasons if the base isn’t designed for it. We build the base for the conditions we actually see here, not the conditions a generic manual assumes. Call (877) 752-4194 for specifics on your driveway.
Under current WUI rules, any combustible edge or landscape wall adjacent to a hardscape needs ember-resistant detailing. Older installs in Mount Hermon often have wood edges or landscape walls that don’t meet the standard. We retrofit the edge with non-combustible materials where needed and make sure the hardscape itself doesn’t become a fire path. Call (877) 752-4194 if you’re not sure whether your existing patio or walkway is compliant.
Usually yes. If the settling is local – a few pavers, one corner, a section along the edge – we lift, re-base, and re-lay just that field. If the base failure runs deep across the whole patio or the slope has shifted the subgrade, replacement starts to make more sense. We’ll tell you honestly which side of that line your project sits on. Call (877) 752-4194 for a no-pressure assessment.
