Unilock Construction in Claremont, CA | Alder Contractors
We install and repair Unilock paver patios, driveways, and retaining walls across Claremont as an independent contractor, not a Unilock-authorized dealer. What sets our work apart here is simple: we know how Unilock profiles behave under San Gabriel foothill sun and Santa Ana winds, and we know Claremont’s design-review and oak-tree ordinances well enough to keep your project moving through approvals. Call (833) 467-7020 for a free estimate on any Unilock paver or wall job in the 91711 zip code.
Why Claremont Residents Choose Us for Unilock Service
Nelson Ibarra learned construction the hard way: weekends on his father’s drywall jobs as a kid in Rialto, then building technology courses at Chaffey College in Rancho Cucamonga. Three decades later, our crew has set Unilock pavers on everything from Village-core Craftsman bungalows to foothill lots north of Foothill Blvd. We’re not authorized by Unilock, and we won’t pretend otherwise. What we offer is practical familiarity with their catalog – Brussels Block, Beacon Hill, Pisa2 estate walls – plus the local permit experience that keeps Claremont projects from stalling at the design-review desk. One contractor, every phase, from the roofline to the backyard.

Common Unilock Construction Problems We Solve in Claremont
- Polymeric joint sand washing out. Santa Ana winds scour exposed foothill driveways fast, and when the joint sand goes, pavers shift and weeds take root. We see this on slopes above Foothill Blvd more than anywhere else in Claremont. We lift, re-set, and re-sand with a joint system that holds.
- Efflorescence on gray-toned Brussels Block. High-sun exposure on south-facing patios pulls salt bloom to the surface, especially where drainage runs across the field and joints were never sealed. It looks like the paver is failing; most of the time it’s a cleaning and sealing fix, not a replacement.
- Tumbled-edge spalling and corner chipping. Older Claremont installations often sat on thin bases over the area’s clay soils. Years of heave and settle chip the edges of Brussels Block and Beacon Hill units. We repair localized damage by lifting and re-laying on a proper compacted base.
- Retaining wall creep on sloped lots. Pisa2 and Estate Wall units lean when they were built without geogrid or with blocked weep points. On Claremont foothill properties, that combination is common. We rebuild with drainage and reinforcement so the wall doesn’t move again.
- Driveway base failure under vehicle loads. A paver driveway on an inadequate subbase will rut and sink within a few years, especially where stormwater pools against the garage. We replace the subbase and re-lay the field rather than patching the same spots repeatedly.
Unilock Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s the thing about building with Unilock pavers in Claremont that a generic contractor won’t tell you: above Foothill Blvd and around the Claremont Colleges, hillside, oak-preservation, and design-review approvals often have to clear before we can excavate or set a paver field. That means your Unilock driveway or patio schedule depends on permit timing in a way a neighboring Pomona or Unilock service in La Verne usually doesn’t. We’ve done enough work in the foothill neighborhoods north of Foothill Blvd to know which projects trigger oak-tree review and which slide through over-the-counter. A paver patio in the flats near the Village might get approved in days; a hillside driveway with a retaining wall can take weeks. We plan the excavation and base work around that reality so you’re not paying a crew to stand around waiting on City Hall.
Unilock Models & Products We Service in Claremont
We work with the Unilock lines most common in Claremont: Brussels Block for classic driveways and patios, Beacon Hill flagstone-textured pavers for courtyards and walkways, Town Hall and Copthorne for permeable-compatible applications, and the Pisa2 and Estate Wall retaining systems. We set field units on genuine manufacturer profiles with matching edge restraint and joint systems. For base aggregate, geotextile, and sealers, we use quality aftermarket materials that hold up to Claremont’s clay soils and hot summers – not cheap filler that fails in three years. If a patio or wall has localized shifting, we lift and re-lay. If the subbase is gone under a heaved driveway, honest replacement is usually cheaper than repeated patch jobs.

FAQs – Unilock Construction in Claremont
Yes. Projects above Foothill Blvd and near the Claremont Colleges frequently trigger hillside, oak-preservation, or design-review requirements before excavation can start. We factor permit timing into the schedule so you know what to expect. Call (833) 467-7020 and we’ll tell you which approvals your specific property likely needs.
They can, mostly by eroding polymeric joint sand and pulling efflorescence to the surface on unsealed gray-toned pavers. Proper jointing and sealing prevents most of it. We re-sand and seal existing fields regularly for Claremont homeowners.
Usually, yes. We keep stock of common Unilock profiles and color blends locally, and we match field units so the repair reads as original rather than patched. If your blend was discontinued, we’ll tell you honestly before we start.
We rebuild it. A leaning Pisa2 or Estate Wall on a sloped lot usually means missing geogrid or blocked weep points, and resetting the face without fixing the drainage just buys you a few years. We add drainage, reinforce, and re-set the units to match the existing wall.
A new Unilock paver driveway in Claremont typically runs $7,000 to $18,000 depending on size, slope, base condition, and permitting. Driveway replacement falls between $5,000 and $14,000. Call (833) 467-7020 for a free, line-item quote.
