Unilock Construction in Upland, CA | Sycamore Contractors
We install and repair Unilock pavers and retaining walls across Upland as an independent hardscape crew. What sets our work apart here is that we plan every base, edge, and drainage detail around the city’s split geology: the expansive clay of the 91786 valley floor performs completely differently than the rocky hillside lots climbing into 91784. One contractor, every phase, from the roof down to the driveway. Call (877) 265-6284 for a free estimate.
Why Upland Residents Choose Us for Unilock Service
Nate Calloway grew up in Temecula’s Redhawk neighborhood and spent two decades running crews across Southwest Riverside County before Sycamore Contractors took shape. He picked up the fundamentals at Palomar College’s construction technology program, and the lesson that stuck is simple: do it right the first time, or you’ll do it twice in the July heat. That’s the standard we bring to every Unilock paver job in Upland.
We’re not a Unilock dealer and we’re not factory authorized. We’re an independent Unilock sales & service crew that reaches for Unilock’s own edge restraint, joint sand, and wall geogrid because we’ve seen what happens when contractors swap in generics. We bring options, you make the call. Whether you’re off Euclid Avenue in 91786 or tucked into a foothill lot in 91784, we quote the job honestly and build it to the standard the brand requires.

Common Unilock Construction Problems We Solve in Upland
- Expansive clay heave on valley-floor driveways. The 91786 side of Upland sits on alluvial fan clay that swells and shrinks with moisture. A base built too thin, or without proper aggregate depth, lifts pavers into ridges and lippage after a single hot Inland Empire summer. We pull the affected section, rebuild the base, and re-set the units flat.
- Hillside runoff undercutting paver edges. On 91784 sloped lots, saturated runoff moves downhill under the hardscape and erodes the bedding layer from below. Edge restraint fails, pavers creep outward, and wall faces start to bulge. We trench, re-establish drainage, and reset the edge with Unilock restraint.
- Polymeric sand breakdown under Santa Ana winds and UV. Upland’s seasonal winds and intense sun grind down cheap joint sand faster than most homeowners expect. Open joints then admit seed and water. We re-sand with Unilock’s specified polymeric product so the joints stay tight through wind season.
- Efflorescence and salt bloom on light-colored units. Poor drainage pitch, often on older Euclid Avenue-corridor rebuilds with mature trees nearby, leaves water pooling against the paver face. Minerals leach out as white bloom. We correct the pitch, clear the drainage path, and clean the affected surface.
- Edge failure from root pressure. Upland’s citrus-era root systems still run under many mid-century lots. Root mass pushes against edge restraint and shifts the outer course of pavers. We excavate past the root zone and re-build with a deeper aggregate base before resetting the edge.
Unilock Service in Upland: What Local Conditions Mean for Your Equipment
Here’s the thing most paver pages flatten over: Upland is two different build environments divided by ZIP code. The 91786 valley floor is flat, expansive clay that moves with every wet-dry cycle. The 91784 foothill lots are sloped, rocky, and loaded with runoff energy. A paver base spec that works on one side of Baseline will fail on the other. And the older Euclid Avenue corridor adds its own complication: those mature citrus-era trees left root systems that still reach under driveways and patios decades after the trees came down. When we pull permits or excavate for a Upland paver job on a grandfathered non-conforming lot, we confirm the legal frontage before setting base, and we bring in an arborist note when roots are involved. That step almost never comes up in the evenly platted tracts of a neighboring city like Rancho Cucamonga, where our Unilock service handles more routine installs. It comes up constantly here. We plan for it from the first estimate.
Unilock Models & Products We Service in Upland
We work with the Unilock lines most common across Upland: Brussels Block and the Brussels Dimensional Series for driveways and large patios, Uni-Stone where a textured Courtstone-style surface fits, Beacon Hill for a tumbled, flagstone look on foothill properties, and the U-Cara retaining wall system when a slope needs structural retention. On parts, we specify Unilock’s own edge restraint, joint sand, and wall geogrid rather than generic substitutes, because the base and edge are where paver jobs actually fail. We stock common joint sand and edge restraint for fast turnaround on Upland repair calls, and order profile-specific units project by project so you’re not paying for someone else’s overstock.

AfterUnilock Service Pricing in Upland
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the number is base depth and site prep, not the paver unit itself. A 91786 clay lot needs more aggregate and possibly a geotextile separator to keep the base from mixing with the clay below. A 91784 hillside job needs drainage correction and reinforced edge restraint. A free estimate from us includes a site walk, a written line-item quote, and an honest read on whether a settled section can be lifted and re-based instead of torn out. Call (877) 265-6284 to schedule yours.

FAQs – Unilock Construction in Upland
Because the soil underneath is completely different. 91786 sits on expansive clay that swells with moisture and shrinks in the dry heat, so base prep there means deeper aggregate, proper compaction lifts, and often a geotextile separator to keep clay from migrating up into the stone. 91784 hillside lots put runoff energy into the equation, so we add drainage correction and reinforced edge restraint so water doesn’t undercut the bedding layer. Same paver, different foundation. Call (877) 265-6284 and we’ll tell you which spec your lot needs.
Yes, and we’ve seen it firsthand. On a mid-century home off the Euclid Avenue corridor in 91786, our crew—like our San Antonio Heights Unilock service team—pulled up a cracked original concrete apron and found citrus-era roots had already heaved two sections of the slab. We excavated past the root zone, built a compacted aggregate base over the expansive clay, set Brussels Block in a running bond with Unilock edge restraint, and re-sanded the joints. That driveway has stayed flat through two summers. Root pressure doesn’t go away on its own. Call (877) 265-6284 for an estimate that accounts for what’s under the surface.
For wind-driven joint wear and UV exposure, we lean toward denser, tighter-fitting profiles like Brussels Block and Uni-Stone, paired with Unilock’s polymeric joint sand rather than a generic. The sand is the first thing the Santa Anas degrade, and once the joints open, every problem follows. Beacon Hill works well for patios where you want a tumbled look, but the joints need the same quality sand. We stock Unilock joint sand locally for Upland repair calls.
In many cases, yes. If the base is otherwise sound and the issue is a settled section or joint sand that’s blown out, we lift the affected paver area, re-compact or add base as needed, re-set the units, and re-sand the joints. We won’t sell a full tear-out when a repair would restore the surface honestly. That said, if the base itself has mixed with clay or washed out on a hillside, a rebuild is the honest call. The estimate tells you which one you’re looking at. Call (877) 265-6284.
No. We’re an independent hardscape contractor, not a Unilock dealer or factory representative. What that buys you is straight talk: if a repair is smarter than a replacement, we’ll say so, because we’re not under any factory program pushing new units. We still specify Unilock’s own edge restraint, joint sand, and geogrid, because those are the parts of the system that actually keep pavers flat. Call (877) 265-6284 for a free estimate.
