Unilock Construction in Montclair, CA | Toolbox Contractors
We provide independent Unilock paver and wall installation, repair, and maintenance across Montclair, CA. The thing that sets our Unilock work here apart is that we’ve spent years working around zero-lot-line setbacks, shared property walls, and side yards too narrow for equipment, which means we plan base, drainage, and access differently than crews used to open suburban lots. If you’re planning a paver driveway, patio, or retaining wall in Montclair, call us at (855) 382-3257 for a free estimate.
Why Montclair Residents Choose Us for Unilock Service
Most contractors can lay pavers. Few have built Unilock projects on the post-war tract lots that define Montclair, where a 30-inch side yard is normal and a forklift often can’t reach the backyard. Our crew has installed Unilock Brussels Block, Beacon Hill, Rivercrest, and Estate Wall systems across the city’s 91763 zip code, and we read Unilock’s technical bulletins and specs before we cut a single paver. Norm Castellano, our owner, grew up in Muscoy just northwest of San Bernardino and spent two decades doing residential framing, roofing, and full gut-and-rebuilds across the Inland Empire before founding Toolbox Contractors. He’s the person who shows up on your Montclair job site, not a rotating cast of subs. Unilock sales & service is a core part of what we do, but we approach every project as a full-scope build, because a paver patio that drains into a failed stucco wall isn’t actually a solution.

Common Unilock Construction Problems We Solve in Montclair
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. After winter rain, white mineral deposits surface on pavers when base drainage is marginal. Montclair’s older homes often have walkways poured directly against slab edges, and that trapped moisture migrates up through the paver joints. We fix the drainage, not just the stain.
- Edge spalling and chipping on Rivercrest pavers. Santa Ana winds whip debris across driveways and patio edges, and narrow Montclair driveways force vehicles to track over paver corners that were never compacted properly. We rebuild the edge restraint and re-compact the base so the chipping doesn’t keep happening.
- Estate Wall settlement and face rotation. Zero-lot-line grading on Montclair’s small lots often leaves too little room for geogrid embedment behind segmental retaining walls. The wall looks fine for a season, then starts leaning. We excavate, re-set the grid at the right depth, and re-level the courses.
- Permeable paver joint sand loss and clogging. Dry Inland Empire summers bake the joint sand, then winter rain washes it out or clogs it, especially against stucco walls where runoff ponds. We re-sand and, when the base has failed, rebuild the section so water actually infiltrates instead of pooling.
- Color and dimension mismatch on repairs. When homeowners add a patio or replace a broken section, generic concrete pavers never match Unilock’s color blends. We source genuine Unilock pavers and wall units so the repair disappears into the existing installation.
Unilock Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair’s post-war tract lots are so narrow that many Unilock service in Ontario and patio installs require hand-carrying pallets through side yards under 3 feet wide. That’s not a minor inconvenience; it’s a planning constraint that changes how we phase the job, where we stage materials, and how long the work takes. Shared property walls add another layer: wall cap and edge restraint details must be coordinated with the neighbor’s grade, because water flowing from your new patio onto their foundation becomes both a legal and a structural problem. On a 1958 stucco tract home near the Pomona border, we tore out a cracked concrete walk and installed Unilock Brussels Block in a running-bond pattern, hand-carrying pallets through a 30-inch side yard because the driveway couldn’t fit a forklift. The original slab had no base course, so we excavated 6 inches, added compacted Class II base, and set the pavers with polymeric joint sand to handle the winter runoff that had been pooling against the stucco. The homeowner gained a stable, drainable path with no more efflorescence bloom after the first rainy season. That’s the kind of project you don’t get from a crew that only works big, open lots in newer subdivisions.
Unilock Models & Products We Service in Montclair
We install and repair Unilock’s Brussels Block and Beacon Hill lines for driveways and walkways, Rivercrest for patio and walk surfaces where a more textured finish works, and Estate Wall for segmental retaining walls up to the heights allowed by Unilock service in Upland plan-check requirements. For repairs and additions, we source genuine Unilock pavers and wall units so color and dimension match existing installations, and we never substitute generic concrete pavers on visible surfaces. When a base or drainage failure is the real cause, we recommend rebuilding that section rather than patching pavers that will simply shift again. We keep common Unilock accessories and edge restraints available for faster turnaround on Montclair jobs, but most project materials are ordered per job to match your existing color blend.

FAQs – Unilock Construction in Montclair
Yes, and we’ve done it many times. The constraint is access for excavation and material staging, which we solve by hand-carrying pallets where needed and phasing the work so you keep driveway use as long as possible. We also check the property line and neighbor’s grade before we set edge restraints, because zero-lot-line grading changes drainage responsibility. Call (855) 382-3257 and tell us what you’ve got, and Norm will tell you what it actually needs.
Efflorescence is mineral salts wicking up through the paver when moisture is trapped beneath the surface. On Montclair’s older slab-adjacent walkways, water often has nowhere to drain because the original concrete was poured without a base course. We fix it by improving drainage and re-setting the pavers on a proper compacted base, not by sealing over the symptom. Call (855) 382-3257 for a site evaluation and a real fix.
Patios at grade generally don’t require a permit. Retaining walls over a certain height, usually 3 to 4 feet depending on current city code, do trigger plan review in Montclair, and walls near property lines or shared walls may require additional review. We check the current City of Montclair requirements on every project and tell you before we quote what’s needed. Call (855) 382-3257 and we’ll walk you through what applies to your lot.
Permeable pavers perform well if the base is built for infiltration, but on older Montclair lots with slab foundations and limited drainage, the subgrade often needs deeper excavation and a drainage outlet to daylight or a dry well. We install permeable Unilock systems with those conditions accounted for, not by following a generic spec. Call (855) 382-3257 for a site-specific recommendation.
Yes. We source genuine Unilock Estate Wall units in the same color blend and dimension as your existing wall, and when the original is older and slightly weathered, we can often blend the new sections so the transition isn’t obvious. If the wall is failing due to settlement, we’ll rebuild the affected section with proper geogrid embedment rather than just replacing face blocks. Call (855) 382-3257 for a free matching assessment.
