Unilock Construction in Montclair, CA | Workshop Contractors
We provide independent Unilock paver and retaining wall installation across Montclair, and the single biggest factor shaping our work here is that the city is fully built out. Nearly every hardscape job we take on in Montclair replaces existing concrete or old pavers rather than breaking new ground, which means demolition access and staging on small 91763 lots drive the schedule more than anything else. We specify Unilock by product line – Brussels Block, Beacon Hill, U-Cara – not by vague “paver” language, because the difference matters on a 5,000-square-foot lot. Call (844) 384-3361 and Noel Figueroa’s team will give you a straight read on your site.
Why Montclair Residents Choose Us for Unilock Service
We’ve been installing Unilock segmental pavers and retaining walls across the Pomona Valley for years, including Unilock service in Ontario, and we approach every Montclair job with an eye toward what the existing conditions will actually allow. Noel Figueroa grew up in the Vineyard neighborhood of Ontario and cut his teeth at Chaffey College’s construction technology program, where job-site work started before he could legally rent a truck. That background translates to a crew that knows how 1950s-1970s tract housing behaves when you add a paver driveway or a low retaining wall to it.
We are an independent installer, which means our base-prep and drainage recommendations are made for your soil and your lot, not for a manufacturer’s sales program. When a Brussels Block driveway in Montclair needs joint re-sanding after winter storms, we don’t upsell you a full replacement unless the subgrade actually failed. And if the subgrade has failed, we’ll show you what’s going on underneath before we recommend anything.
We also carry the broader general contracting scope that matters on these older Montclair properties. A paver patio that butts up against a failing stucco wall, a garage conversion that needs hardscape finish work, a kitchen remodel that extends into a backyard entertaining space – one contract covers it. You’re not coordinating a paver crew with a framing crew and hoping they talk to each other.

Common Unilock Construction Problems We Solve in Montclair
- Edge raveling at driveway aprons. Montclair’s small lots concentrate water runoff at a handful of exit points, and the joint between a Unilock paver driveway and the concrete gutter takes the brunt of it. Winter rains scour the sand from those joints and the edge pavers start to loosen. We rebuild the apron transition with proper edge restraint and compacted base so the water moves past the pavers instead of through them.
- Efflorescence on Brussels Block. The Pomona Valley’s hot, dry summers alternating with wet winters create the exact conditions for salt bloom on tumbled pavers, especially where they sit against north-facing stucco walls that hold moisture. It’s cosmetic, not structural, but we treat it properly – cleaning, drying, and sealing where appropriate – rather than telling you it’ll just go away.
- Polymeric sand failure on legacy installs. A lot of the older Unilock driveways in Montclair were built over 2-3 inches of decomposed granite because that’s what budget crews used in the 1980s and 1990s. That base can’t handle the thermal expansion and contraction of Pomona Valley summers, and the joints rut and sink. We pull the pavers, rebuild the base with compacted Class II aggregate, and re-lay with proper joint sand.
- U-Cara wall settlement and tilt. Low planter walls and seat walls built without geogrid or drainage gravel behind them fail visibly after a few Santa Ana wind seasons. The soil behind dries out, the wall shifts, and the facing blocks tilt forward. We rebuild those walls with proper drainage and reinforcement so they hold square through decades of Montclair weather.
- Lipped and heaving pavers from tree roots and clay soil. The flat lots in the 91763 core often have mature trees too close to hardscape, and the clay-heavy soil expands and contracts with moisture. Pavers lip over an inch, trip hazards appear, and the surface looks wavy. We re-level where the base is sound and replace where it isn’t, and we’ll tell you honestly which one you need.
Build it right the first time. The second time costs twice as much and nobody’s happy about it.
Unilock Service in Montclair: What Local Conditions Mean for Your Pavers
Montclair is fully built out, so virtually every hardscape we touch replaces existing concrete or pavers rather than breaking new ground – and demolition of old slabs on narrow 91763 lots means hauling and staging access, not excavation, drives the schedule. If you’ve got a 1960s concrete driveway that needs to come out before Brussels Block goes in, the crew needs a path for the jackhammer spoils, the old rebar, and the new base material. On a 50-foot lot with a detached garage set inches from the rear property line, that path is your front driveway, and it changes the sequencing of the entire job. Add in the original detached garages common on Montclair’s postwar blocks – many sitting within inches of the rear property line – and you’ve got a setback-and-survey problem as much as a construction one. We survey first, stage smart, and keep the street clear. That’s not brand talk; that’s how we handle every job, from Montclair to Unilock repair in La Verne. how you actually get a Unilock installation done in this city without turning your front yard into a debris field for three weeks.
Unilock Models & Products We Service in Montclair
We install and service the full Unilock residential hardscape line, including Unilock sales & service across Montclair and the surrounding Pomona Valley. The model lines we work with most often here are Brussels Block for driveways and patios, Beacon Hill for flagstone-look walkways, U-Cara for segmented retaining walls and planters, and Town Hall and Copthorne for permeable and standard interlocking applications. When a job calls for matching existing pavers or wall units, we source genuine Unilock product so the color and dimensional tolerances match the field. The hidden layer is where we use regional materials instead: compacted Class II aggregate for the base and quality polymeric sand for the joints, because that’s what actually holds up under Montclair’s thermal cycling and winter storm runoff.

FAQs – Unilock Construction in Montclair
Not reliably, and we don’t recommend it. An overlay traps water between the old slab and the pavers, and Montclair’s winter rains plus the clay-heavy soils under 1950s-1970s slabs will eventually heave and crack the overlay. We’re happy to evaluate your slab, but in most 91763 cases the right move is demolition and a proper compacted base. Call (844) 384-3361 and we’ll give you an honest assessment.
Usually the underlying base wasn’t compacted properly, or the edge restraint failed and water is scouring the joints from the sides. On Montclair’s small lots, runoff concentrates at the driveway apron and the low edge along the house, and those are the first places sand washes out. We fix it by re-compacting the base, repairing edge restraint, and re-sanding with quality polymeric sand. For an exact diagnosis, call (844) 384-3361 – estimates are free.
Yes, in most cases. We source genuine Unilock Brussels Block in the same color family, and because Unilock maintains consistent tolerances across production runs, the new pavers sit flush with the old field. We’ll blend the new product with salvaged pavers from the edge of the existing patio so the transition isn’t obvious.
Montclair’s building department generally requires permits for retaining walls over a certain height, and even low walls can trigger review if they’re near a property line or affect drainage. We handle the permit process as part of the project, and we’ll tell you upfront whether your wall falls under the threshold. It’s one less thing to guess about on a small lot.
Once the polymeric sand is activated and cured, which is typically 48 to 72 hours depending on weather. That timeline matters in Montclair because the hot summers can cure the sand faster, but our crew will give you a specific walk-through when we finish. Call (844) 384-3361 to schedule your project and we’ll map out the full timeline.
