Unilock Construction in Upland, CA | Timberline Contractors
We’re an independent Unilock installation and service provider working across Upland’s foothill, flats, and downtown districts. We place and repair genuine Unilock paver and wall systems, and our crews handle what makes Upland genuinely different: historic-preservation submittals near Euclid Avenue and expansive-soil base preparation on the 91784 hillside lots. If you’re pricing a Brussels Block driveway, a Beacon Hill patio, or an Estate Wall terrace in Upland, call (866) 253-5808 for a free estimate from a contractor who reads plan-check overlays before the first base course goes down.
Why Upland Residents Choose Us for Unilock Service
Plenty of hardscape crews can drop pavers on sand. That’s not the hard part here. The hard part in Upland is what’s underneath: older citrus-grove-era lots in the central flats with decades of compacted, sometimes unpredictable fill, and foothill parcels where expansive soil moves with every wet winter and dry Santa Ana season. Our crew over-excavates, reinforces with geogrid where the soil report demands it, and details drainage before a single Unilock unit is placed. It’s the difference between a patio that stays flat and one that heaves in three years.
Nelson Fung, our owner and general contractor, learned materials the old way: watching his grandfather haggle over tile at the Broadway hardware stalls in Chinatown, then getting formal training at Los Angeles Trade-Technical College before spending years on everything from Eastside bungalow remodels to mid-size commercial work. That background is why we specify genuine Unilock units and their proprietary joint sand instead of color-match aftermarket pavers. Dimensional tolerance is what holds a pattern together, and shortcuts show up as lippage within a season. We’ve also got Unilock sales & service knowledge that covers the full model range, not just one or two lines.
If you live in Upland and want a hardscape contractor who will actually explain why your base matters more than the finish on top of it, we’re the crew.

Common Unilock Construction Problems We Solve in Upland
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. Upland’s hot, dry summers pull moisture up through the units, and winter rains drive it back down. The proprietary surface densifiers on these lines can trap salts near the face unless a breathable sealer is specified. We see the chalky white bloom most often on unshaded west-facing driveways and patios that got sealed with a film-forming product. The fix is re-cleaning, a breathable sealer, and joint sand that lets the assembly dry properly.
- Edge spalling and joint sand loss on hillside lots in 91784. Expansive and creeping soil along the foothill edge moves enough to work paver edges loose when the base wasn’t over-excavated. This shows up as chipped edges, wandering joint lines, and sand that keeps washing out after every rain. We rebuild these with deeper base, geogrid reinforcement, and proper edge restraint, because piecing in new pavers over a moving foundation just repeats the failure.
- Estate Wall segmental retaining wall bulging or toe kick-out on north-side slopes. When drainage aggregate and underdrain pipe get omitted to save depth against a property line, water builds up behind the wall and pushes it outward. We’ve repaired several of these on hillside terraces where the original installer treated a retaining wall like a decorative garden border. It’s not decorative when it’s holding back a slope.
- Fading and surface chalking on Seneca Valley wall caps and pavers. Unshaded Santa Ana wind exposure and UV near the foothills are brutal on all paving, but we see accelerated chalking on west-facing driveway aprons and wall caps that weren’t sealed or were sealed with the wrong product. The units themselves are still sound; the surface just needs the right treatment.
- Historic-district driveway failures near downtown. On parcels near Euclid, some older concrete driveways were poured over minimal base during mid-century construction. When they fail and the city review process kicks in, homeowners sometimes rush a replacement with whatever’s cheapest and fastest. That’s how you end up with a paver driveway that looks fine for one season and then settles at the edges. We handle the submittal paperwork and the base work together.
Unilock Service in Upland: What Local Conditions Mean for Your Equipment
Here’s the thing about Upland that doesn’t show up in generic hardscape marketing: two lots a mile apart can face completely different plan-check paths. A hillside parcel off Mountain Avenue in 91784 gets scrutinized under wildland-urban-interface fire-code requirements, meaning your hardscape choices interact with defensible-space rules, ember-resistant detailing, and sometimes fire-department access requirements. A downtown parcel near Euclid, especially on a Craftsman or Spanish Colonial Revival street, may trigger historic-preservation review, which means a materials-and-color submittal before you can order a single Unilock paver. Flatter neighboring cities to the south don’t carry that downtown overlay. That’s not a small detail: it changes what you can build, what it costs, and how long it takes. We read both sets of requirements before we spec a paver or a wall, because ordering the wrong color or missing a submittal deadline costs weeks.
On a 1950s ranch in the 91786 flats, we tore out a cracked concrete driveway and installed a Brussels Block paver driveway on an over-excavated, geogrid-reinforced base after finding the original slab had heaved from expansive soil. We detailed a hidden drainage swale and re-sanded with Unilock’s proprietary joint sand, and the driveway has stayed flat through two Santa Ana seasons.
Unilock Models & Products We Service in Upland
We install and repair every major residential Unilock line: Brussels Block for driveways and walkways, Beacon Hill for patios where the tumbled edge suits older Upland homes, Estate Wall for segmental retaining walls on the north-side slopes, and Seneca Valley for caps, steps, and aprons that need a cleaner profile. We also handle Unilock repair in Montclair when homeowners there need the same level of base-work expertise. We keep common Unilock units and their proprietary joint sand on hand for fast turnaround on repair jobs in Upland, and we specify genuine Unilock product rather than aftermarket look-alikes because the unit tolerances are what hold a pattern. If a wall or driveway is failing from base or drainage issues, we rebuild that section correctly rather than piecing in new units over a bad foundation.
If you’re planning a larger project like an addition or ADU that includes hardscape, we handle the full scope as your general contractor: the paver work ties into our Upland service area coverage for interior and exterior building under one contract.

AfterUnilock Service Pricing in Upland
Unilock work in Upland is priced by the square foot, the site conditions, and the base work required. A flat-lot patio on stable soil is a different job from a hillside driveway that needs over-excavation and geogrid. Here are the ranges we quote most often:
| Project | Typical Upland Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition (with hardscape) | $45,000 – $130,000 |
What changes the number? Soil condition, existing base quality, drainage needs, access for equipment, and whether your parcel triggers historic or WUI review. Our free estimate includes a written line-item quote and a walkthrough of what your specific Upland lot actually needs. Call (866) 253-5808 to schedule yours, and we’ll give you the real number, not a ballpark.

FAQs – Unilock Construction in Upland
It can. If your home sits in a designated historic district or is a contributing structure near Euclid, the city may require a materials-and-color submittal before you order pavers. This means choosing a Unilock line and color that the review board accepts. We prepare that paperwork as part of the job, so you don’t lose two weeks discovering you picked the wrong paver after delivery. Call (866) 253-5808 and we’ll check your parcel first.
Expansive and creeping soil moves under shallow base. If the installer didn’t over-excavate and reinforce with geogrid, the pavers move with the soil, and you get edge spalling, joint sand loss, and wandering lines. The fix is rebuilding the base, not replacing individual pavers. On Upland’s foothill side, we treat any paver project as a soil job first and a paver job second.
In Upland, it’s almost always a maintenance issue, not a product defect. The hot, dry summers pull moisture upward, winter rains push it back down, and the salts bloom on the surface. A breathable sealer and re-sanding with Unilock’s proprietary joint sand solve it permanently. If someone sealed the pavers with a film-forming product, that’s usually the root cause. We’ll strip it, clean the units, and apply the right sealer. For an exact cost, call (866) 253-5808.
Yes, with two added layers: the wall needs proper drainage aggregate and underdrain pipe so it doesn’t bulge or kick out, and the surrounding area has to respect defensible-space rules and fire-department access. We’ve built Estate Wall terraces on foothill parcels where both requirements applied. The wall holds, the drainage works, and the fire marshal signs off. It costs more than a decorative wall because it’s doing real structural work.
Yes. Many of the ranch homes in Upland’s central and southern flats are getting additions or ADUs, and the hardscape has to be planned with the building work, not after it. We bring the same approach to our Rancho Cucamonga Unilock service for clients expanding their properties there. We handle both scopes as a general contractor so the paver driveway, patio, and the new structure are built on the same understanding of the lot’s soil and drainage. Give us a call at (866) 253-5808 and we’ll walk the property together.
