Unilock Construction in Oak Hills, CA | Timberline Contractors
Unilock paver driveways and patios in Oak Hills, CA typically cost $3,500 – $18,000 depending on square footage, base prep, and paver line. We’re Timberline Contractors, an independent Unilock service provider based nearby, and the thing that sets our Oak Hills work apart is simple: we’ve dug through this town’s caliche layer enough times to know it changes the entire job. Call (866) 253-5808 for a free estimate. We’re not manufacturer-authorized, and that means we tell you straight when a cheaper paver from another brand does the job better.
Why Oak Hills Residents Choose Us for Unilock Service
Nelson Fung, our owner and general contractor, learned masonry and hardscaping the old way: on job sites across the LA basin, then years of high-desert work in San Bernardino County, including Unilock repair in Hesperia. He can look at a settled paver edge on a 1.5-acre Oak Hills parcel and tell you whether the base failed or the caliche underneath did. That’s the kind of diagnostic skill that saves you money.
We handle the full scope of Unilock work: driveway and patio installation, retaining wall construction with Unilock Estate Wall, paver repair, re-leveling, joint sand replacement, and drainage fixes. Because we’re a full-service general contractor, we can also tie your paver patio into a pergola, outdoor kitchen, or stucco repair without handing you off to three different crews.

Common Unilock Construction Problems We Solve in Oak Hills
- Caliche-related base failure. Caliche is a calcium carbonate hardpan that sits just below the surface across much of Oak Hills. When a contractor skips proper excavation and lays Unilock pavers over it, the base can’t drain, and pavers start cracking or sinking within two or three seasons. We over-excavate and bring in clean, compacted base every time.
- Freeze-thaw heaving. Winter nights in Oak Hills drop below freezing, and the freeze-thaw cycle pushes poorly compacted sand and gravel upward. Unilock pavers sitting on an unprepared base shift out of plane, leaving raised edges and trip hazards. We compact in lifts and use freeze-thaw-rated joint sand.
- High-desert wind erosion of joint sand. Spring winds out of the Cajon Pass strip polymeric sand from joints quickly on exposed Oak Hills properties. We use an industrial-grade polymeric sand and, on large driveways, recommend edge restraints that hold up to heavy wind exposure.
- Flash flooding washout. Sudden summer thunderstorms send water racing down ungraded Oak Hills driveways. If your Unilock paver base lacks proper drainage and edge restraint, you’ll see sand wash out and pavers peel away at the edges. We grade for sheet flow before a single paver goes down.
- Settling over old utility trenches or prior non-permitted work. Many Oak Hills homes had DIY or unpermitted additions, including driveways and patios. We uncover buried trenches, old septic lines, or poorly filled excavations that cause Unilock pavers to settle unevenly. We excavate, correct the subgrade, and re-lay the area.
Unilock Service in Oak Hills: What Local Conditions Mean for Your Equipment
Oak Hills is unincorporated San Bernardino County, which means one thing for Unilock paver construction: the county, not a city building department, signs off on everything. County plan checks for driveway and patio installations run on their own schedule, and projects must meet San Bernardino County setbacks, grading, and drainage rules. Most out-of-town contractors — even those offering Unilock service in Victorville — don’t factor those weeks into their timeline, and homeowners get stuck holding a torn-up driveway with no approved plan. We schedule for county timeline realities from the first bid. On top of that, the caliche varies wildly: one lot off Ranchero Road will stop a backhoe cold at 14 inches, while the next parcel digs clean to 24. We probe for caliche before bidding so the excavator, not your checkbook, takes the hit.
Unilock Models & Products We Service in Oak Hills
We install and repair a focused set of Unilock lines that perform well in Oak Hills conditions: Brussels Block for large driveways and patios, Beacon Hill for a cleaner tumbled look, Copthorne for heavier vehicle loads, and Estate Wall for retaining walls and raised planters. When pavers crack or settle, we source genuine Unilock pavers to match the existing color and texture. For edge restraints and joint sand, we select aftermarket products rated for high-desert freeze-thaw cycles and wind exposure. If less than 20% of your pavers are failing and the base is intact, we repair. Past that, we’ll tell you honestly that replacement costs less per year than chasing patches.

FAQs – Unilock Construction in Oak Hills
Caliche stops drainage and ruins base compaction, so Unilock pavers installed over unbroken caliche will crack and settle within a few seasons. We over-excavate through the caliche and bring in clean, angular base rock compacted in lifts. It’s the single most important step for paver longevity in Oak Hills. Call (866) 253-5808 if you suspect caliche on your parcel.
Yes, typically. Since Oak Hills is unincorporated, San Bernardino County handles permitting, and paver driveways affecting drainage or setbacks almost always require county plan check before work starts. We handle the permit application, drawings, and county inspections as part of the job, just as we do for Unilock in Mountain View Acres.
Unilock Brussels Block and Copthorne hold up best under Oak Hills freeze-thaw because they’re dense, with tighter joints that resist heaving when the base is properly compacted. Beacon Hill works well for patios with lower vehicle loads. We’ll recommend a line based on your specific parcel conditions.
Sometimes, but we rarely recommend it on Oak Hills lots. Existing concrete often hides drainage problems or has already cracked from caliche and freeze-thaw. If your slab is sound, a concrete overlay with Unilock pavers can work, but we’ll probe the base and tell you if full removal is the better long-term call.
Most Unilock paver patios in Oak Hills run $3,500 to $11,000, with caliche excavation and drainage grading adding to the final number. Smaller patios on clean-digging parcels land at the low end. Call (866) 253-5808 for a free estimate; we’ll give you an exact figure after probing your soil.
