Unilock Construction in Gilroy, CA | Millwright Builders
We provide independent Unilock paver, wall, and step installation and repair across Gilroy, including 95020 and 95021. What separates our Unilock work here from a generic paver crew is that we plan every base, edge restraint, and drainage detail around what Gilroy actually throws at hardscape: clay-heavy valley soil, wet winters, and a lot of rural parcels where residential and agricultural code paths overlap. Call (866) 925-0334 for a free estimate on your Unilock project. We’re not owned, authorized, or endorsed by Unilock. We’re a licensed Gilroy General Contractor who has installed Unilock product lines on infill lots, ranch parcels, and foothill builds in Gilroy for years, and we service what we build.
Why Gilroy Residents Choose Us for Unilock Service
Most paver failures in Gilroy are not paver failures. They’re base failures, edge failures, or drainage failures that happen to show up at the paver. Noel Castañeda, our owner, learned early in his trades career that a good structure doesn’t happen by accident, it happens by decision. That’s why our Unilock work starts with what’s under the paver, not just the paver itself. When we set Brussels Block on a Gilroy lot with clay-heavy soil, we’re thinking about whether that clay expands after winter rains, whether the original grade actually moves water away from the house, and whether the edge restraint can hold up to the truck that’s going to roll over it next week.
We carry Unilock’s own edge restraints, joint sand, and accessory products where the spec calls for them, and we pair them with quality compatible base and geogrid materials underneath. The paver face is rarely the real problem. An honest repair, meaning re-leveling, re-sanding, and replacing a failed restraint, usually beats a full tear-out. We’re local to the South Bay and Peninsula, so we know what Gilroy’s permit office expects and how long things take out here. For a broader look at where we work, see our Gilroy service area page. And for general Unilock product knowledge, our Unilock sales & service page covers the lines we install and repair.

Common Unilock Construction Problems We Solve in Gilroy
- Joint sand washout and paver pumping. Where a Unilock field was set on Gilroy’s clay-heavy soil without a capillary break or positive drainage, the first wet winter does real damage. Pavers look fine from above, but they rock underfoot because the joint sand has washed out and water has nowhere to go. We excavate to stable soil, build a compacted aggregate base with a drainage plane, and re-set the field properly.
- Edge restraint failure on driveway aprons and patio perimeters. Gilroy’s rural roads mean field-equipment traffic and trucks cross residential hardscape more than people expect. A light plastic edge can’t take that load. The field spreads, the cuts open up, and suddenly the driveway looks older than it is. We replace restraint with Unilock’s own system or a heavier compatible alternative, then re-compact the perimeter.
- Efflorescence and surface staining on tumbled Brussels Block. Gilroy’s agricultural dust and irrigation overspray settle into the textured surface of tumbled pavers. It’s cosmetic, but it reads as product failure unless the cleaning and sealing regimen is right. We handle paver cleaning, efflorescence removal, and sealer application matched to the paver type and sun exposure.
- Settlement at patio-to-house transitions. On older single-story homes in downtown Gilroy, the original stoop or walkway was often poured on uncompacted fill. When a new Unilock base section isn’t deep enough, the transition sinks. We see this regularly on 95020 remodels. Fixing it means correcting the base, not just re-laying the top course.
- Heaving after winter rains. Clay expands when wet and contracts when dry. A Unilock patio or walkway built on a thin base over Gilroy clay will heave and shift within a season or two. We deepen the base, add proper grading, and install geogrid where the soil calls for it.
Unilock Service in Gilroy: What Local Conditions Mean for Your Hardscape
Here’s what nobody tells you about Unilock work in Gilroy that you’d never hear in San Jose or Morgan Hill. The rural parcels east and west of town routinely mix agricultural outbuildings and shops with the house, and those structures get permitted under different code thresholds than residential work. So a paver driveway or patio tie-in we build on those lots often has to be drawn to whichever code path the outbuilding is permitted under, not the house’s. That affects how we phase the project, what the permit office needs to see, and whether certain drainage or access details get reviewed twice. On an older single-story stucco home off the downtown grid in 95020, our crew pulled up a heaved original concrete walkway and found it poured straight over loose fill. We excavated down to stable soil, set a compacted aggregate base with a drainage plane, and laid a Brussels Block walk and patio with Unilock edge restraint tied to the house line. After the first winter rains, the field stayed flat and the joints held. The homeowner’s complaint about sinking pavers was a base problem, not a paver problem. That’s the pattern in Gilroy: the soil and the permit path decide whether hardscape holds up, and the paver just takes the blame.
Unilock Models & Products We Service in Gilroy
We install and repair the Unilock lines most common on Gilroy properties. Brussels Block and Brussels Dimensional Set are the workhorse pavers for driveways, walkways, and patios. Beacon Hill tumbled wall block serves low seating walls and garden borders. For retaining walls, we work with Bristol Valley and Estate Wall segmental systems, including the geogrid and drainage components those walls require to hold on sloped foothill lots. We stock Unilock’s own joint sand, edge restraints, and accessories where the spec calls for them, and we keep quality compatible base materials ready for fast turnaround across 95020 and 95021. If a paver color or profile has been discontinued, we’ll tell you straight and show you what matches closest or whether a bounded repair makes more sense than a full re-field.

AfterUnilock Service Pricing in Gilroy
Hardscape pricing in Gilroy tracks two things: the amount of site work the soil demands and the access constraints on the lot. Infill lots wedged between active fields can mean tighter equipment access and more hand work. Ranch parcels can mean longer base runs and heavier drainage corrections. Either way, our estimates are written as line items, not ballparks. Here’s what Unilock work typically runs in this market:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives cost on Unilock projects isn’t always the paver itself. It’s the excavation depth, whether we’re removing an old failing slab or walkway, how much base material the soil needs, and what kind of edge restraint the traffic pattern demands. Your free estimate includes an on-site look at the grade, the existing hardscape, and the access path. Call (866) 925-0334 and we’ll give you a number you can plan around.

FAQs – Unilock Construction in Gilroy
Yes. We do this regularly on the ranch parcels east and west of Gilroy. The key is that the outbuilding may be permitted under an agricultural code path with different setback, drainage, or access requirements, so the paver driveway or turnaround often needs to be drawn to match that outbuilding’s permit, not just the house’s. We handle that coordination with the Gilroy permit office before we cut any base, and we offer Unilock repair in San Juan Bautista as well. Call (866) 925-0334 and we’ll walk you through what applies to your parcel.
Because Gilroy sits on clay-heavy valley soil that expands when wet and contracts when dry. If the original base was too thin or there was no drainage plane, the whole field moves with the soil. The fix is re-excavating to stable ground and rebuilding the base properly, not just re-setting the top layer. We see this on older downtown homes and newer subdivision lots alike.
No. Unilock pavers are sold through dealers, and any licensed contractor can purchase and install them. We are an independent hardscape and remodel contractor, not an Unilock-authorized dealer or affiliate. What matters for the warranty and the long-term performance is whether the installer follows Unilock’s base, joint, and restraint standards. We do, and we document the base before the pavers go down.
Yes, in most cases. We match the paver line and color as closely as the current Unilock catalog allows, and we’ll show you samples before we commit. If the original line has been discontinued, we’ll tell you which current profile comes closest and whether the repair should be bounded or blended. Matching is faster and cleaner when the existing field is in good shape, so the sooner we look at it, the better your options are.
We plan access first. Some infill lots in 95020 and 95021 have tight side yards, standing water after field irrigation, or equipment traffic that crosses the job site. We bring in smaller equipment where needed, stage materials carefully, and build the base with extra attention to drainage. The estimate reflects the access, so there are no surprises once we start. Call (866) 925-0334 for a free site walk.
