Unilock Construction in Montclair, CA | Square Deal Contractors
We provide independent Unilock sales & service across Montclair, including paver driveway and patio installation, repairs, and full rebuilds. The thing that separates our Unilock work here from anywhere else: nearly every project in Montclair butts up against an existing block wall on a narrow lot, and that wall dictates how we set drainage and grade. If you’re planning a paver driveway, patio, or hardscape project in Montclair, call (866) 623-7205 for a free estimate. We’re Square Deal Contractors, and we’ve been working these tight Pomona Valley lots long enough to know where the water goes before the first paver drops.
Why Montclair Residents Choose Us for Unilock Service
We install Unilock pavers on Montclair’s post-war ranch lots every week, so we understand how Brussels Block, Pasadena, and Beacon Hill units behave against block walls, mature street trees, and the inland heat that bakes the Pomona Valley from June through October. If you need Unilock in Claremont, we know those same conditions apply just east of here. Nolan Breckett, our owner, grew up in Lake Forest and learned construction through Saddleback College’s construction technology program, where the hands-on coursework taught him to think about base prep and drainage before aesthetics. That’s the lens we bring to every Unilock job in Montclair. As an independent installer, we’re not authorized by Unilock, which means our loyalty sits with the base, the edge restraint, and the drainage plane under your pavers, not with a dealer program pushing specific product lines. We’ll tell you exactly what you’re getting and why.

Common Unilock Construction Problems We Solve in Montclair
- Sand-joint washout and paver settlement on old driveway aprons. Montclair’s 1950s and 1960s ranch homes often still have their original garage slab aprons, and the base under those aprons was rarely compacted in lifts. When we pull up a failing apron, we find loose base material that’s been shifting for decades. Re-laying pavers over that without rebuilding the base is a waste of your money, and we’ll say so plainly.
- Efflorescence on grey-toned pavers along north-side patios. Montclair homes with patios tucked tight to a north-side block wall get consistent shade, which means pavers stay damp longer after rain. That’s exactly where salt bloom shows up on Brussels Block and Catalina Grana. It’s cosmetic and cleanable, but it catches homeowners off guard after the first wet season.
- Edge-creep and spalling at the driveway apron where pavers meet the street cut. The Pomona Valley’s summer heat cycles expand and contract pavers daily, and any driveway that’s seen heavier traffic, especially during an ADU build when contractors run loads up the drive, is going to show movement at the street edge and where you should have used a proper edge restraint system.
- Drainage ponding on narrow side yards. In Montclair, your side yard is likely tight to a property-line block wall, and if the original grading wasn’t set with positive fall toward the street, water ponds against the wall and the paver base. We see this on older homes where the lot was graded level to squeeze every usable inch.
- Paver heave from tree roots on mature street trees. Montclair’s established canopy means many driveways and patios share space with mature tree roots. Roots lift pavers slowly and unevenly, creating trip hazards and drainage flat spots that get worse every year.
Unilock Service in Montclair: What Local Conditions Mean for Your Equipment
If you live in Montclair, you already know the city’s built out. ZIP 91763 is essentially full, which means new construction is infill: ADUs, lot splits, second-story additions, and tear-down rebuilds on narrow post-war SFR lots. That changes how we set Unilock pavers. On a typical Montclair job, the paver driveway or patio abuts an existing block wall on at least one side, and that wall, not the pavers, is the real design constraint. We set sub-base drainage and positive fall so water moves toward the street or an approved drainage swale, never pooling against your neighbor’s wall or your own foundation. Homes along the Holt corridor and the numbered streets south of Arrow have some of the tightest side-yard setbacks we work with, and we’ve learned to treat the wall as the datum line for the entire installation. If the wall’s footing is higher than your garage slab, the pavers have to step or grade accordingly. That’s the detail most drive-by quotes miss, and it’s the reason your project needs a contractor who actually walks the lot first.
Unilock Models & Products We Service in Montclair
We work with the full range of Unilock paver lines you’re likely considering for a Montclair driveway or patio. Brussels Block is our most-requested paver down here for its tumbled, dimensional look that suits the ranch-era homes. Pasadena gives you that cobble-style texture without the cobble price. Beacon Hill reads like flagstone and works well for more organic patio layouts. Catalina Grana offers a clean, textured slab look for contemporary rear-yard designs. For repairs, we source Unilock’s own matching units and color runs so patches blend with existing installations, and we pair those with quality aftermarket polymeric joint sand and edge restraint. We also handle Unilock repair in La Verne with the same sourcing discipline. We don’t skimp on base aggregate, ever. If a 1950s-era driveway apron has failed base, we’ll tell you honestly that re-laying pavers over it will fail again, and a full rebuild is the right call.

FAQs – Unilock Construction in Montclair
In most Montclair cases, no. Overlaying pavers on an existing 1960s concrete driveway traps moisture and salts, and if the slab has cracks or settlement, the pavers telegraph those flaws within a season. We’ll evaluate your slab, but our honest recommendation on old aprons is almost always full replacement with proper base. Call (866) 623-7205 for a site assessment.
Yes, if the base is graded with positive fall away from the wall and toward the street or a drainage swale. On Montclair’s tight side yards, that often means cutting a subtle slope across the entire paver width, which most installers miss. We set the wall as the high point and grade from it.
Unilock pavers are fired concrete units and they handle heat far better than poured concrete slabs, which crack. Santa Ana winds are more of a concern for joint sand displacement if you’re still using standard sand. We use polymeric sand, which hardens and resists wind scour. After the late-summer heat breaks, we set the joints so they cure properly.
Efflorescence is a natural salt migration, common on Montclair’s shaded north-side patios. It’s cosmetic. We use a paver-specific efflorescence cleaner and then let the pavers cycle through a season. Don’t power-wash it alone, it’ll just push salts deeper and they’ll return. For a proper cleaning recommendation, call (866) 623-7205.
For a like-for-like driveway or patio replacement on your own lot in Montclair, typically no. But any expansion of hardscape, changes to drainage patterns, or work that affects the street right-of-way will likely require a permit. We’ll tell you what needs a permit before you sign anything, which is exactly how we operate on every job.
