Unilock Construction in San Jose, CA | Viceroy Construction
We install and service Unilock paver systems across San Jose for patios, driveways, and full landscape hardscaping projects. The difference in our work here comes down to this: San Jose’s heritage-tree ordinance, orchard-era clay soil, and ranch-slab tear-outs demand a different base-prep strategy than what a generic paver crew will do. We’re an independent Unilock service provider, not a manufacturer-authorized dealer, which means we quote the product line that fits your soil, drainage, and tree-root conditions instead of what a distributor is pushing that month. Call (877) 358-6557 for a free estimate. You can also see our Unilock sales & service overview for the full scope of what we handle.
Why San Jose Residents Choose Us for Unilock Service
Unilock pavers live or die by what’s underneath them. That’s where we spend our time, and it’s where most San Jose paver failures start. Neil Drummond grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where he learned to read soil before touching a paver. Three decades of South Bay construction work taught him what ranch-lot clay and mature valley oaks do to a paver base. We work from Unilock’s published base-prep and jointing specs, not site-by-site guesswork. When we level a settled Brussels Block field in Willow Glen, we’re checking the base depth, the edge restraint, and the drainage path before we quote anything. Our San Jose service area covers the neighborhoods where this work gets complicated, from the Rose Garden to the old orchard lots west of downtown. The details you don’t see are the ones that matter most.

Common Unilock Construction Problems We Solve in San Jose
- White, chalky haze on gray-toned pavers: Efflorescence blooms after San Jose’s dry-season irrigation cycles and winter rains. It’s almost always a capillary moisture issue in the base, not a paver defect. We diagnose the base and drainage before recommending anything, because sealing over a moisture problem just traps salt under the surface.
- Settling edges and soldier courses on clay lots: Adobe clay on the orchard-lot side of San Jose swells and shrinks seasonally. Pavers laid over an undersized sub-base heave at the edges first. We re-excavate to proper depth and re-compact with open-graded aggregate that gives that expansive soil room to move without moving your patio.
- Rutting and joint-sand loss on driveways over old ranch slabs: In ZIPs 95110 through 95113, a lot of paver driveways went in over the original postwar concrete. The slab cracks, and the crack telegraphs through the paver bed as rutting. We pull the pavers, address the slab, and rebuild the base so the two systems stop fighting.
- Staining and salt migration around pool decks: San Jose’s hard water plus heavy summer hose-downs leaves mineral staining on pavers near pools and patios. Joint sand pulls salt upward through capillary action. We re-grade, re-joint, and in some cases switch to a permeable system that drains through instead of wicking up.
- Root-driven heave under mature oaks: Heritage oaks and redwoods push shallow roots into anything rigid underneath them. Concrete slabs crack; pavers lift. We work with root zones rather than cutting through them, which keeps the tree healthy and your paver field flat.
Unilock Service in San Jose: Why Heritage Trees Change How We Build
Here’s something most San Jose homeowners learn the hard way: San Jose’s heritage-tree ordinance means a mature valley oak or redwood shading a backyard often can’t be removed to make room for a patio or ADU base excavation. The city requires a permit and arborist review, and in the older orchard-lot neighborhoods west of downtown, that review can stop a project cold. We design around it. A Unilock permeable or open-graded system lets us build up a compacted aggregate base that works around root zones and passes arborist review without cutting through the flare. On a Willow Glen ranch lot off a tree-lined street, a homeowner wanted a Unilock Brussels Block patio where a 60-year-old oak’s roots had already heaved the old concrete—exactly the kind of Unilock repair in Buena Vista and nearby neighborhoods we handle regularly. We hand-excavated around the critical root zone, built an open-graded base with a permeable joint system so runoff stays on site, and set the field with edge restraint clear of the root flare. The patio drains clean through the October-to-April rains and the tree never got flagged by the arborist. A generic crew would’ve cut the roots, poured a slab, and left the homeowner holding a dead tree and a city fine. That’s the difference.
Unilock Models & Products We Service in San Jose
We work across Unilock’s core product lines: Brussels Block for traditional looks, Beacon Hill Flagstone for a more natural broken-edge surface, Town Hall for larger-format applications, and the Elegance line when the project calls for a permeable or structural system with Transfer or Senna wall units. For repairs, we source genuine Unilock units and matching OEM joint sand and edge restraint so the system stays compatible. For San Jose turnaround, we stock common replacement units locally. That means a settled field in Cambrian, a popped edge in the Rose Garden, or Unilock repair in Seven Trees doesn’t sit for two weeks waiting on a special order from the Midwest. If a field just needs re-leveling and re-sanding, we’ll say so and do that, not sell you a teardown. But when the base itself has failed, only a rebuild lasts, and we’ll tell you that straight too.

AfterUnilock Service Pricing in San Jose
San Jose paver pricing tracks the scope of the base work. A simple patio over an existing compacted area costs less than a driveway over a failing ranch slab, because the latter means slab handling, deeper excavation, and more aggregate. Here’s where our San Jose General Contractor pricing generally lands:
| Service | Price Range |
|---|---|
| Paver Patio Installation | $4,130 – $12,980 |
| Paver Driveway Installation | $8,260 – $21,240 |
| Driveway Replacement | $5,900 – $16,520 |
What drives cost: tree-root work, slab tear-out, drainage corrections, and the permeable vs. standard system decision. Your free estimate includes a site walk, base assessment, and a written line-item quote with the product line named. Call (877) 358-6557 to schedule one.

FAQs – Unilock Construction in San Jose
Yes, and that’s exactly how we design these projects. San Jose’s heritage-tree ordinance requires a permit and arborist review if you’re planning to remove a protected valley oak or redwood. We avoid that entirely by building a permeable or open-graded Unilock base around the critical root zone, not through it. The system passes arborist review and the tree stays. Call (877) 358-6557 if you’ve got a big oak in the way, we’ll assess it at no cost.
That’s efflorescence, and in San Jose it’s usually capillary moisture wicking through the base during dry-season irrigation cycles and winter rains. It’s not a paver defect. The fix is usually drainage and base work, not sealing the surface, which traps salt underneath and guarantees the problem comes back worse. Call (877) 358-6557 for a diagnosis.
No, but only if the base is done right over the slab that’s under it. Many 95112 homes have the original postwar concrete underneath newer surface work. Concrete cracks and the crack moves upward through whatever’s on top. We address the slab, then build an open-graded Unilock base with proper jointing so the two layers stop working against each other. That’s the long-term fix. Call (877) 358-6557 for a site assessment.
Yes. Because Viceroy Construction is a full-scope general contractor, a Unilock patio can be scoped as part of the same project as an ADU build or home addition. One contractor, every trade, one point of contact. That means the paver base goes in with the ADU’s drainage plan, not around it after the fact. We’ll coordinate the entire scope so the hardscape and the structure work as one system. Call (877) 358-6557 to discuss tying both together.
Brussels Block is a traditional rectangular paver with a tumbled edge, tighter joints, and a more formal look. Beacon Hill Flagstone has a broken, irregular edge and wider joints that handle a bit more movement, which can help on clay-lot San Jose backyards where the soil expands in winter. Either one works; the right choice depends on your soil, drainage, and how much tree-root activity is in the yard. Call (877) 358-6557 and we’ll walk your lot with you.
