Unilock Construction in San Antonio Heights, CA | Hampton Contractors
Our General Contractor in San Antonio Heights provides independent Unilock paver installation, repair, and replacement across the community. The one thing that makes our Unilock work here different is simple: we build for foothill terrain, not flat valley lots. Sloped pads, switchback driveways, and county-level permitting shape every base we compact and every edge we restrain. Call (833) 467-4075 for a free estimate on any Unilock project in the 91784 ZIP.
We’re Hampton Contractors, led by Brent Calloway, and we’ve been laying Unilock pavers and retaining walls on San Antonio Heights’ sloped, alluvial-fan lots for years. We’re an independent Unilock service provider, not authorized by Unilock, but our crew has handled everything from driveway aprons to WUI-compliant patio edges in this foothill community. For broader Unilock sales & service across the region, we cover the full brand line with OEM-level materials and a repair-first assessment approach.
Why San Antonio Heights Residents Choose Us for Unilock Service
Unilock pavers behave differently at 1,800 feet of elevation than they do down in the valley, which is why our Ontario Unilock service crew takes a different approach up here. The freeze-thaw cycles are milder, but the runoff is faster, the Santa Ana winds hit harder on ridge-top lots, and the mineral content in hillside water leaves its mark on paver surfaces. Our crew has worked this terrain long enough to know what holds and what doesn’t.
Brent Calloway grew up just off Ranchero Road in Hesperia and has been working construction in the High Desert since he was eighteen. He picked up his foundational trade skills at Victor Valley College, where the construction technology program gave him a working vocabulary for everything from framing loads to finish carpentry. That background matters when we’re engineering a paver base that has to hold on a 12-percent grade through a wet winter. Good work doesn’t need a disclaimer.
We stock Unilock-specific base materials, geotextile, and polymeric sand locally, so we’re not waiting on a supplier run from down the hill when your driveway apron fails. For homeowners across the San Antonio Heights service area, that means faster turnaround on paver repairs and replacements without a week of prep work.

Common Unilock Construction Problems We Solve in San Antonio Heights
- Base settlement on sloped lots. Unilock pavers on graded pads often shift when runoff channels under the base, especially after winter storms. We see this most often on properties where the original builder poured a minimal base and relied on sand-set leveling, which the county wouldn’t approve today on a steep lot.
- Edge restraint failure. Santa Ana winds and rapid runoff can displace plastic edge restraints on driveways and patio perimeters, causing pavers to spread outward. We replace plastic with concrete edge restraint on any San Antonio Heights project where the grade exceeds 5 percent.
- Efflorescence and staining. Mineral-rich water from hillside runoff can leave white deposits on Unilock pavers, particularly on north-facing slopes that dry slowly. We clean and reseal affected areas after correcting the drainage that caused the mineral buildup in the first place.
- Surface abrasion from wind-blown sand. Exposed patios and driveways on ridge-top properties see finish wear faster than valley installations. Brussels Block and Beacon Hill pavers can develop a dull, sand-scoured appearance within a few years on the windiest lots.
- Root intrusion from hillside oak and chaparral. Native roots seeking moisture under paver bases can lift sections of a patio or walkway. We install root barriers where the native planting comes close to hardscape edges, which most valley contractors never think to do.
Unilock Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is unincorporated, so paver driveway and retaining wall permits go through San Bernardino County, not a city building department. That sounds like a small administrative difference, but it changes the whole project timeline and design approach. County plan check moves at its own pace, and because the community sits in a Cal Fire very-high fire severity zone, county reviewers often require noncombustible hardscape borders and defensible-space clearance before they’ll sign off on a new paver driveway or patio.
What that means for Unilock owners is that a paver patio isn’t just a paver patio here. The county may ask for a five-foot noncombustible border around the hardscape edge, which usually means concrete or decomposed granite rather than wood mulch or shrub planting right up against the pavers. We design Unilock installations with that requirement already in mind, so you’re not revising drawings mid-permit or paying for change orders because the plan checker flagged your landscape edge.
Hillside drainage is the other piece. Properties off Mountain View Avenue and the switchback roads above 24th Street carry storm water down from the San Gabriel foothills at a rate the flat valley grid never handles. Our Unilock base specs account for that: over-excavated subgrade, geotextile separation, compacted aggregate, and drainage swales where the lot’s natural contour wants to send water. Skip any of that on a San Antonio Heights sloped lot and the pavers will tell you within two winters.
Unilock Models & Products We Service in San Antonio Heights
We work across the Unilock lines most specified in foothill residential work: Brussels Block, Elegance, Beacon Hill, and Sierra. Brussels Block is the one we see most often on existing driveways and patio retrofits, while Elegance and Beacon Hill show up on newer builds and whole-yard renovations. Sierra is common for steps and accent bands on hillside terraces.
Our parts stance is straightforward: we use Unilock’s OEM-level base materials, compacted aggregate, geotextile, and polymeric sand, matched to the specific paver line. We never substitute sand-set over native soil on a San Antonio Heights slope. When a paver field fails, we first assess whether the base and edge restraint can be salvaged. If not, we recommend full replacement with a properly engineered base rather than patching, because re-laying over failed subgrade just delays the next failure by a season or two.

Here’s what Unilock work typically runs in the San Antonio Heights market. The slope of your lot, the size of the field, and the condition of the existing base are the three biggest cost drivers. A failed base that needs full over-excavation costs more than a paver field that can be salvaged and re-laid.

|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |

FAQs – Unilock Construction in San Antonio Heights
Yes, in most cases. Since San Antonio Heights is unincorporated, permits go through San Bernardino County, and the county treats paver driveways as a grading and drainage matter, not just a cosmetic surface. You’ll likely need a site plan showing drainage patterns, base depth, and hardscape borders. We handle the permit package as part of the project. Call (833) 467-4075 and we’ll tell you what your specific lot will require.
A sloped lot means water moves faster across and under your pavers, so the base has to be deeper, the geotextile has to be right, and the edge restraint has to be concrete, not plastic. On grades over 5 percent we also add drainage swales where the lot’s natural contour directs runoff. Flat valley contractors often skip these steps because they don’t need them down the hill. On a San Antonio Heights hillside, skipping them means pavers that shift within two winters.
The pavers themselves are noncombustible, so they’re a solid choice for the WUI zone. The bigger issue is what’s around them: the county may require a noncombustible border around your hardscape, and you’ll need to keep brush clearance up against the paver edge. Santa Ana winds also sand-blast paver surfaces on exposed ridge-top lots, so we recommend a quality sealer on the most exposed elevations. Call (833) 467-4075 and we’ll assess your specific exposure.
Driveway replacement on a San Antonio Heights lot typically runs $5,000 to $14,000, depending on square footage, slope, and how much of the old base has to be over-excavated and hauled out. A steeper lot with a failed subgrade will land toward the higher end. Estimates are free. Call (833) 467-4075 for a line-item quote on your driveway.
We can match the paver line, yes. Brussels Block, Elegance, Beacon Hill, and Sierra are all available in current Unilock inventory. The challenge is that sun-bleached and sand-scoured pavers next to fresh ones will show a color difference, so we’ll talk you through whether spot-repair or full-field replacement makes more sense for your property. We won’t sell you a patch that looks like a patch. Call (833) 467-4075 and we’ll walk the site with you.
