AfterUnilock Construction in Lancaster, CA | Penhallow Remodeling
Unilock construction service in Lancaster, CA means building paver driveways, patios, and segmental retaining walls that survive Antelope Valley clay, wind, and solar-mandate trenching. We’re Penhallow Remodeling, an independent Lancaster construction firm led by Trevor Nash. We install and repair Unilock hardscapes across Lancaster and the surrounding desert communities. If your paver driveway is heaving or your retaining wall is cracking, call us at (936) 259-2607 for a written quote.
Why Lancaster Residents Choose Us for Unilock Service
We’ve installed Unilock segmental retaining walls, pavers, and permeable systems across Lancaster for years, and we also offer Unilock service in Santa Clarita. Not as an authorized Unilock dealer. As a crew that knows how these specific units behave in high-desert soil conditions. Trevor Nash spent the better part of two decades working residential construction across Southern California before starting Penhallow Remodeling, and he approaches every job the same way: give me the whole picture first, then we pick up the tools. That means we look at your soil, your drainage, your solar conduit runs, and your wind exposure before we ever quote a paver installation. We’re also the company that puts the price and the guarantee in writing before work starts. The 365-Day Done Right Promise comes with every project. If the hardscape fails inside a year, we come back and make it right at no charge. That’s the Kingswell standard we’ve operated under since 2004.
We handle Unilock sales & service with a repair-before-replace mindset. When matching an existing wall or paver field, we use genuine Unilock OEM units, caps, and joint sand. When the OEM accessory won’t solve a Lancaster-specific problem, we specify aftermarket geogrid, drainage aggregate, and polymeric sand built for expansive clay and high wind. You get a written price before we start, a defined arrival window, and background-checked uniformed technicians on site. A live person answers our phone 24/7.
Common Unilock Construction Problems We Solve in Lancaster
- Efflorescence and salt staining on Brussels Block and Beacon Hill pavers. After winter rain, Antelope Valley clay soils hold moisture against the paver base. During freeze-thaw cycles, that moisture wicks dissolved salts up through the pavers, leaving white chalky deposits on the surface. We remove the staining at the source and re-slope the base drainage so moisture doesn’t linger against the block.
- Edge spalling and joint sand loss on Treo permeable pavers. Lancaster’s high-velocity winds scour loose joint sand fast, and our UV index degrades polymeric sand faster than what coastal installers see. We re-spec joint sand for desert conditions and install wind-resistant edge restraints so the outside courses don’t start flaking and rotating.
- Differential settlement and lippage in paver driveways. When a paver driveway was laid over a base that wasn’t engineered for Lancaster’s shrink-heave clay, individual pavers start sitting proud or sinking. We pull the failed section, re-compact the base with thickened-edge detail, and relay the same units so the surface reads level again.
- Retaining wall block cracking and rotation. Unilock segmental walls installed without proper geogrid reinforcement on expansive soils will crack and lean as the ground heaves each season. We rebuild with the geogrid and aggregate drainage layers the original install skipped.
- Driveway edge collapse along paver borders. Where wind and clay cycles erode the base at the outer edges, the entire edge course starts dipping toward the street or the neighbor’s fence. We repair the base, recompact it properly, and lock the edge back in so it doesn’t repeat.
Unilock Service in Lancaster: What Local Conditions Mean for Your Equipment
Lancaster became the first city in the United States to mandate solar panel installation on all new residential construction in 2013. That’s years ahead of California’s statewide rule and it changes how every Unilock hardscape project on a ground-up build has to be sequenced. On any new home in Lancaster, roof-mounted solar conduit runs and inverter locations get laid out during the permit stage. That conduit often crosses the driveway or patio footprint. We engineer the sub-base and conduit sleeves together rather than treating the hardscape as a standalone pour. On a 1990s stucco tract home in the Quartz Hill area of Lancaster, our crew-working alongside our sister General Contractor in Lancaster operations-tore out a heaved Unilock Brussels Block driveway that had settled unevenly after years of clay shrink-heave and wind-driven joint sand loss. We re-compacted the base to expansive-soil spec, installed geogrid, re-laid matching Brussels Block units with fresh polymeric sand, and tied the new paver field into the home’s solar conduit sleeve so the roof array stayed undisturbed. The driveway has stayed level and locked through two full freeze-thaw seasons. A contractor from Santa Clarita or Palmdale who doesn’t do Lancaster permits every week won’t have that sequencing wired into their process. We do.
Unilock Models & Products We Service in Lancaster
We work on Brussels Block, Beacon Hill, Treo, and Umbriano. Brussels Block and Beacon Hill are the workhorse tumbled pavers we see most often on Lancaster driveways and walkways. Treo is the permeable line, and it needs a different base spec here because Lancaster wind and UV eat standard joint sand. Umbriano is the flagstone-texture paver we specify when homeowners want a more dressed look for a patio or pool surround. For matching repairs, we keep a local stock of OEM Brussels Block and Beacon Hill units in the common Lancaster color blends so turnaround doesn’t sit on a manufacturer lead time. For new installs, we order Unilock directly and coordinate delivery around your paver base prep, which usually takes two to three days depending on access and compaction testing.
Unilock Service Pricing in Lancaster
Paver work in Lancaster costs more than it does in coastal cities because the base engineering is heavier. Expansive clay means thickened edges, geogrid, and compaction testing that a beach city contractor skips. Here are the line-item ranges we quote from:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives the number up or down: square footage, base condition, whether we’re matching existing Unilock units or starting fresh, and whether your project needs solar conduit coordination with the city of Lancaster. Every estimate is written, line-itemed, and fixed. The number on day one is the number on the invoice. Call (936) 259-2607 to schedule a free estimate.

FAQs – Unilock Construction in Lancaster
Yes, when the base is engineered for shrink-heave clay. The failure we see most often is a paver driveway laid on a standard 4-inch base with no thickened edge and no geogrid over expansive soil. Lancaster’s clay expands in wet winters and contracts in dry summers, cycling every year. That movement is what heaves pavers. We build bases with thickened-edge detail, compaction testing, and geogrid where the soil report calls for it. If your existing pavers are already heaving, the fix is re-engineering the base under the affected area, not just re-laying the surface. Call (936) 259-2607 for an exact assessment and written quote. Estimates are free.
Yes. Since Lancaster’s 2013 solar mandate, every new residential build here requires solar from the permit stage. That means conduit runs and inverter placement are part of the site plan before we ever cut into the grade. We sequence the paver base and sub-base around the conduit sleeves so the roof array stays connected and the driveway stays level. Contractors from outside Lancaster don’t carry that permit-stage habit, and it shows in the punch list. When we install Unilock on a new Lancaster build, the solar coordination is baked into the plan from the first site visit, just as we do with our Bathroom Remodeling in Lancaster projects.
That’s efflorescence. Lancaster’s clay soils hold moisture against the paver base after winter rain, and during freeze-thaw cycles that moisture wicks dissolved salts through the paver surface. The salt dries as a white chalky deposit. Cleaning it off only works if the moisture path gets fixed. We re-slope the base drainage and install a proper drainage layer so water doesn’t sit against the bottom of the pavers. Then the surface gets cleaned to remove the mineral residue. If the staining returns after one Lancaster winter, we come back under the 365-Day Done Right Promise and fix it at no charge. Call (936) 259-2607 to schedule a look.
Yes. We keep OEM Beacon Hill units in the common Lancaster color blends on hand for matching repairs. The failed units get pulled, the base behind them gets re-compacted and re-graded, and the replacement blocks go in with matching joint sand. Full replacement only makes sense when the base course has failed across the installation, not when a handful of units cracked at the corner. We’ll tell you which situation you have, and we’ll give you a written price for the repair before we touch a block.
Lancaster’s persistent high-velocity winds scour loose joint sand and accelerate UV degradation of polymeric sand. The outside rows of a paver field lose their joint material first, then the pavers start shifting and spalling at the edges. We install wind-resistant edge restraints on every paver field in Lancaster, and we spec polymeric sand rated for high-UV desert exposure rather than the standard coastal product. If your edges are already starting to move, call (936) 259-2607 before the movement reaches the middle of the driveway. The repair gets more expensive as the field destabilizes.
