Unilock Construction in Claremont, CA | Milpitas Construction
We install, repair, and rebuild Unilock paver systems across Claremont, CA, with a focus on what actually holds up under this city’s inland sun, clay soil, and hillside drainage patterns, and we also provide Unilock repair in Upland. The thing that separates our Unilock work in Claremont from every other installer’s: we scope pavers and retaining walls to pass the Village and Claremont Colleges historic-design review before ordering a single pallet of material. Ken Stafford and the Milpitas Construction crew have been laying Unilock units around the San Gabriel foothills long enough to know when a paver job needs a rebuilt base rather than a cosmetic reset. If you’re planning a paver driveway, front walk, patio, or retaining wall in Claremont, call (877) 752-4194 for a free, written estimate.
Why Claremont Residents Choose Us for Unilock Service
We’re an independent Unilock sales & service contractor, and that independence matters more in Claremont than most people realize. Here’s why: we’re not tied to manufacturer upsells or a sales quota. When we walk a Claremont property and see a paver driveway that’s already failed at the base, we say so plainly. Re-laying those same units over bad sub-grade buys a season or two at best. Rebuilding the base is almost always the cheaper long-run call, and we’d rather tell you that before you spend than after the first Santa Ana rain exposes the shortcut.
Ken got his construction technology training at Evergreen Valley College, then spent the next two-plus decades learning what works and what doesn’t in Southern California soil. He’s seen enough failed hardscape in the foothills to know that cheap base prep is the most expensive mistake a homeowner can make. His approach: “Build it right the first time, the Bay Area doesn’t give you a free pass on shortcuts.” He brought that same thinking down to Claremont, where older Craftsman lots near the Colleges have a way of punishing slapdash grading.

Common Unilock Construction Problems We Solve in Claremont
Claremont’s climate and housing stock create a specific set of Unilock failure patterns. These are the ones we see most often:
- Sun-chalking on lighter pavers in sunny front yards: Claremont’s intense inland UV exposure fades lighter Unilock lines like Brussels Block and Beacon Hill faster than you’d see in coastal cities. We handle re-sealing, selective unit replacement, and in some cases a full re-lay with a color family better suited to the property’s sun load.
- Joint-sand washout on sloped foothill lots: When rainy-season runoff moves across a paver patio or driveway on a hillside parcel, polymer sand gets flushed out and joints open up. We see this constantly in the slopes above Claremont. If grading wasn’t corrected before base compaction, it’s not a reseal, it’s a rebuild.
- Edge heaving and paver movement on expansive clay: Older lots around the Colleges sit on clay-heavy soil that swells when wet and shrinks when dry. That cycle slowly pushes paver edges outward. We correct it with a compacted aggregate sub-base and proper edge restraint, not just a cosmetic re-set.
- Retaining wall block movement on hillside properties: A Unilock U-Cara wall without properly engineered drainage will eventually shift when Santa Ana wind-driven rain saturates the slope behind it. We see this on hillside lots throughout the northern and eastern edges of Claremont. The fix is drainage, not bigger blocks.
- Rutting and base failure on driveways over old fill: Post-war tract homes on Claremont’s north and east sides often have pavers laid over decades-old fill that was never properly compacted. The result is rutting where car tires track. We excavate, re-compact, and reinstall with a sub-base that holds.
Unilock Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s the thing a generic Unilock page won’t tell you about Claremont: much of the Village and the streets ringing the Claremont Colleges sit under historic-preservation review, so a paver driveway or front-walk replacement that’s visible from the street can require sign-off on unit color, pattern, and edge restraint. It’s not just a building permit. It’s a design-review process, and the city’s reviewers look hard at whether new hardscape matches the Craftman and Period Revival character of the surrounding blocks. For a homeowner, that means you can’t just pick a paver because you like the color. You need to pick a unit and pattern that will pass review, and you need to know that before you order thousands of dollars of material. We scope Unilock selections specifically to what Claremont’s design-review board will approve, which saves our clients weeks of revisions and more than one costly reorder. On a Craftsman-era lot near the colleges, our crew pulled up a settled Brussels Block walk where the original installer had laid pavers directly over graded soil with no compacted aggregate base. We excavated and re-compacted the sub-base, reset the existing units to match the home’s period character, and added edge restraint and drainage fall away from the foundation. The result held through the next rainy season without the ponding the old walk had trapped against the porch.
Unilock Models & Products We Service in Claremont
We work with the full Unilock paver line most common in Claremont service area applications, including Brussels Block, Beacon Hill, Town Hall, and the U-Cara retaining wall system. When a repair calls for matching existing pavers, we source genuine Unilock units that blend with the original color family. For base, edging, and joint sand, we spec materials that meet or exceed Unilock’s installation guidance. What we keep on hand for Claremont jobs: aggregate base material, edge restraint, and polymer joint sand in the colors most commonly used on local residential installs. Special-order Unilock units typically arrive within a few business days, which keeps most repair projects on a short timeline.

FAQs – Unilock Construction in Claremont
Yes, in most cases. Paver driveways and front walks visible from the street in the Village and around the Claremont Colleges fall under historic-preservation review, which means the city looks at unit color, pattern, and edge restraint before issuing a permit. Plan on the review step taking a few extra weeks. It’s not optional, and it’s not skippable. We scope paver selections specifically to pass review, which saves you from ordering material twice. Call (877) 752-4194 for a free site assessment.
That’s a drainage and slope issue, not a paver defect. When runoff moves across a sloped lot without proper grading or drainage paths, it lifts poly sand right out of the joints. The fix is correcting the fall and compaction, then reinstalling the pavers with proper edge restraint and joint stabilization. Patching the sand alone won’t hold through the next storm. We’ll tell you exactly what your slope needs, and the estimate is free.
Yes. We source genuine Unilock Brussels Block units to blend with your existing color family, and we pay close attention to surface wear so the new units don’t look like a patch. On older installations, slight color difference from UV exposure is expected, but we minimize it by selecting units from the same production batch where possible. Smaller repairs can often be done in a day once materials are on site. Call (877) 752-4194 and we’ll take a look.
Completely different. A hillside wall behind a foothill property carries lateral load from saturated soil during storm events, and Santa Ana wind-driven rain only pounds the slope harder. Flat-lot walls mostly hold back level grade. Hillside Unilock walls need engineered drainage behind the face, geo-grid or reinforcement on taller runs, and a base that can handle wet-season slope pressure, just as we apply for Unilock service in San Antonio Heights. Skimp on any of those and the wall will move. We’ve rebuilt enough failed hillside walls to know where the corners get cut, and we don’t cut them.
No. Milpitas Construction is an independent general contractor that installs and repairs Unilock products. We’re not affiliated with, authorized by, or sponsored by Unilock. That’s actually an advantage for you, because we’re free to recommend exactly what the site needs, including Unilock when it’s the right product and something else when it isn’t.
