Unilock Construction in Oak Hills, CA | Milpitas Construction
We provide independent Unilock paver and retaining wall service across Oak Hills, Unilock in Phelan, and the surrounding high desert. We’re not a manufacturer-authorized dealer, and we won’t pretend to be. What we are is a full-scope general contractor that sources Unilock units through the brand’s own dealer network and installs them to Unilock’s published base-prep and compaction specs, which matters more out here than most people realize. If you’re planning a paver driveway, patio, or a retaining wall on a multi-acre Oak Hills lot, call (877) 752-4194 for a free estimate.
Why Oak Hills Residents Choose Us for Unilock Service
Ken Stafford, our owner, has spent more than two decades on job sites across the high desert and the Bay Area, and one thing he’ll tell you straight: a paver job is only as good as the base under it. That’s the whole conversation in Oak Hills. We spec Unilock’s own matching units, edge restraints, and polymeric joint sand on every repair, tie-in, and rebuild, so what we add matches what you already have. No color-matching guesswork from a big-box aisle. No patching with a unit that’s close enough.
We’re also one of the few general contractors around with active access to 50-plus brand-name product lines, which means your Unilock hardscape doesn’t live in a vacuum. If your paver driveway job turns into a conversation about the retaining wall behind it, or the roof runoff that’s been undercutting the edge, we’re already the contractor holding the whole project. One point of contact, one contract, and we spec materials by name so you know exactly what’s going into your property.

Common Unilock Construction Problems We Solve in Oak Hills
- Efflorescence and sun-chalking on Brussels Block and Cambridge Cobble. The high-desert UV in Oak Hills is brutal on paver faces, especially when a previous sealer was laid down too thick. You get a white, chalky film that won’t rinse off. We correct it properly rather than coating over it again.
- Joint sand washout and paver shifting. Winter nights out here can drop below freezing, and expansive soils heave with the cold. If the original base compaction was undersized, you’ll see paver courses drift apart and joints hollow out. We recompact and re-sand with Unilock’s polymeric product so the field locks back together.
- Edge restraint blowouts. Oak Hills gets real wind. On exposed multi-acre lots with no windbreak, a paver field without a proper concrete edge collar will creep outward until the perimeter units pop loose. We pin a new collar and reset the edge to hold.
- Hairline cracking and capstone separation on Ledgestone walls. When footings aren’t cut below the local frost depth, the wall moves just enough to crack the face and walk the caps. We rebuild the footing first, then the wall skin.
- Base failure under driveways. We replace heaved paver driveways where the original installer laid units directly over expansive soil with no separation fabric. The pavers themselves are often still good; the ground under them isn’t.
Unilock Service in Oak Hills: What Local Conditions Mean for Your Equipment
Here’s what’s specific to Oak Hills: every paver job here sits in a San Bernardino County high fire hazard severity zone. There’s no city hall, so plan checks and permits run through the County, and that review process looks at defensible-space clearances and noncombustible edge conditions. In practical terms, your paver driveway or patio layout has to respect fire-safe setbacks, and your retaining wall can’t butt right up against a structure in a way that traps embers or blocks a fire crew’s access. A tract-lot paver installer in Victorville or Hesperia will never think about this; we plan around it on every Oak Hills job from the first site visit.
We also deal with the soil itself. Oak Hills is built on expansive high-desert ground that swells with winter moisture and shrinks in summer heat. That’s why we won’t lay a Unilock field over a thin base of sand and hope for the best. We excavate to depth, compact in lifts over a stabilizing fabric, and set the edge restraint in concrete. On one multi-acre lot off a rural Oak Hills road, we replaced a heaved Brussels Block driveway where the original base had been laid directly over expansive soil with no geotextile separation. We excavated to depth, re-compacted in lifts with a stabilizing fabric, reset the existing units on a fresh base, and pinned a concrete edge collar so the field holds against wind and winter heave. The homeowner kept the mature pavers and only paid for the rebuild underneath.
Build it right the first time. The high desert doesn’t give you a free pass on shortcuts.
Unilock Models & Products We Service in Oak Hills
We install and repair the full Unilock residential lineup you’ll see across Oak Hills properties: Brussels Block, Beacon Hill, Cambridge Cobble, and Ledgestone walls and cap units. For repairs and tie-ins, we stay with Unilock’s own matching units rather than swapping in a lookalike from another manufacturer. Color and dimension drift is real, and it shows up in high-desert sunlight. We keep common matching units and edge restraints coming through Unilock’s Unilock sales & service dealer network, so turnaround for a standard repair in Oak Hills is measured in days, not weeks.

FAQs – Unilock Construction in Oak Hills
No. Milpitas Construction is an independent contractor serving Oak Hills. We source Unilock products through the manufacturer’s own dealer network, but we are not manufacturer-affiliated or authorized. What you get is a licensed general contractor who installs to Unilock’s published specifications, and who will repair or rebuild your hardscape properly rather than point you back to the dealer.
Yes, in Oak Hills they often will. Because this is an unincorporated San Bernardino County area in a high fire hazard severity zone, hardscape plans may need to maintain defensible-space clearances and noncombustible edge conditions. A paver patio up against a wood-framed wall with no clearance can flag a plan-check issue. We can walk your property and tell you what’s workable before you spend money on a drawing. Call (877) 752-4194 and we’ll take a look.
We stay with Unilock’s own matching units, edge restraints, and polymeric joint sand. Aftermarket or lookalike units drift in color and dimension, and that mismatch reads instantly in bright high-desert light. We’d rather source the right unit than save you forty dollars on something you’ll squint at for ten years.
Most paver patio installations in Oak Hills run three to five working days from excavation to final compaction and joint sand. A standard repair, like resetting a heaved section or replacing a cracked unit, is usually a single day. County plan checks, when required, add review time before we start. We’ll give you a straight timeline at the estimate.
A Unilock paver driveway in Oak Hills typically runs $7,000 to $18,000, while a concrete driveway replacement is usually in the $4,500 to $12,000 range. Pavers cost more up front, but they also don’t crack across the whole slab when the ground heaves; you reset the affected section instead of tearing out the pour. For an exact number on your lot, call (877) 752-4194. Estimates are free.
