Unilock Construction in Rancho Santa Margarita, CA | Ashbury Contractors
We’re an independent Unilock service provider installing and repairing paver driveways, patios, and retaining walls across Rancho Santa Margarita. Most of our work here starts the same way: a homeowner calls because pavers have shifted or a wall is bowing, and the root cause is almost always the expansive clay under the original 1990s grading. We fix the base, not just the surface. Call (833) 467-4091 to schedule a free estimate, and we’ll tell you exactly what’s happening under your pavers before we quote a single line item.
Why Rancho Santa Margarita Residents Choose Us for Unilock Service
Noel Quintero has spent over two decades diagnosing why hardscape fails in south Orange County, and he’ll tell you the paver is rarely the problem. The base is. Rancho Santa Margarita sits on graded hillsides with expansive clay that swells when wet and shrinks when dry – and that movement is what pushes pavers out of place. We also know the HOA process here cold. Nearly every subdivision in 92688 has an architectural review committee with approved paver colors and patterns, and we’ve navigated enough design-review submittals to know which Unilock lines get approved the first time.
We source genuine Unilock pavers and wall blocks so color and dimensional match are never a gamble. And because we’re a full-scope general contractor, we handle everything from the paver edge to the drainage correction behind it – one contract, one accountable party, no finger-pointing when something goes sideways. Our Unilock sales & service experience covers the product line deep enough that we specify the exact series before we quote the price.

Common Unilock Construction Problems We Solve in Rancho Santa Margarita
- Paver migration and joint sand loss on sloped driveways. The expansive clay in Rancho Santa Margarita’s hillside subdivisions moves with every wet winter and dry summer. When the subgrade shifts, pavers creep downhill and joint sand washes out, leaving gaps that catch Santa Ana wind-driven debris. We correct the base compaction and install edge restraints that actually hold.
- Efflorescence and surface staining on Brussels Block pavers. HOA-managed landscapes here tend to have aggressive irrigation schedules, and that overspray combined with our hard water leaves white mineral deposits on pavers that were never properly sealed. We remove the staining and apply the right sealer for inland foothill sun exposure.
- Retaining wall block cracking or bowing on hillside lots. The original 1990s grading in Rancho Santa Margarita didn’t fully account for slope stability on steeper lots. When we see a Unilock Estate Wall leaning, it’s almost always a drainage issue behind the wall, not a block failure. We excavate, correct the drainage, and rebuild with proper geogrid reinforcement.
- Paver heaving and settlement around pool decks and patios. Poor compaction from the original build plus clay soil movement equals sunken pavers and trip hazards. We pull the affected area, rebuild the base with proper lift compaction, and relaid the Unilock pavers so they sit flush and drain correctly.
- Discontinued paver matching after partial repairs. Homes built in the late 1980s through 2000s often have Unilock lines that are no longer manufactured. We identify the closest current series in the right color range, or source quality aftermarket alternatives with your written approval before any work begins.
Unilock Service in Rancho Santa Margarita: What Local Conditions Mean for Your Equipment
Here’s what separates Unilock work in Rancho Santa Margarita from the same job in a neighboring city: your HOA architectural review committee has a say in what goes on the ground. Almost every home in this master-planned community falls under a homeowners association with documented CC&R restrictions, and the design-review submittal process is not optional. In the Trabuco Highlands neighborhood off Antonio Parkway, we replaced a failing paver driveway where the original 1990s installation had settled unevenly due to expansive clay. Before any demolition happened, we pulled the HOA’s approved color palette, matched it to a Unilock Brussels Block series, and submitted the plans. After approval, we removed and reinstalled the base with proper compaction and drainage correction, then laid the new pavers in the HOA-approved color. The driveway passed final inspection without a single revision request. That sequence – HOA approval first, then excavation – is the difference between a project that finishes on schedule and one that stalls for months. We’ve done enough Rancho Santa Margarita jobs to know the committees, the color palettes, and the common objection points. It’s why our Rancho Santa Margarita service area work moves faster than contractors who treat this city like anywhere else.

FAQs – Unilock Construction in Rancho Santa Margarita
Most Rancho Santa Margarita HOAs approve the neutral earth-tone Unilock lines: Brussels Block, Beacon Hill, and Cambridge in their standard color ranges. Each subdivision’s architectural review committee has its own approved palette, so we pull the specific list for your address before recommending a series. Call (833) 467-4091 and we’ll confirm what your HOA will pass on the first submittal.
Expansive clay swells when wet and shrinks when dry, which creates vertical movement under the paver base. If the subgrade wasn’t over-excavated and compacted properly, you’ll see paver settlement, heaving, and joint sand loss within a few seasons. We correct this with deeper excavation, geotextile separation fabric, and proper compaction lifts before any Unilock paver goes down.
Yes, and most of the time the block itself is fine. A bowing Unilock Estate Wall usually means water is trapped behind it, or the original build didn’t include geogrid reinforcement. We excavate behind the wall, install drainage tile and clean aggregate, rebuild with proper geogrid layers, and re-lay the existing block where it’s structurally sound. The fix is permanent when the drainage is right.
A Unilock paver driveway in Rancho Santa Margarita typically runs $7,000 to $18,000 depending on square footage, slope correction, and drainage work. HOA-approved colors don’t usually add cost, but discontinued paver matching can. Call (833) 467-4091 for a written line-item quote, and we’ll walk you through exactly where the money goes.
Yes, in this inland foothill climate—like you’ll find with Unilock in Mission Viejo—we recommend sealing Unilock pavers to prevent efflorescence from hard-water irrigation overspray and to reduce fading from the intense dry-summer sun. We use a breathable, film-forming sealer rated for clay paver systems and reapply every few years. It keeps HOA landscapes looking sharp and makes Santa Ana dust blow off instead of sticking.
