Unilock Construction in North Tustin, CA | Timberline Contractors
We’re an independent paver and hardscape contractor who installs and repairs Unilock systems across North Tustin’s hillside estates and ranch properties. The thing that shapes Unilock work here more than anything: North Tustin is unincorporated, so driveway and patio projects run through OC Public Works in Santa Ana, not a city counter, and the clay soils on these half-acre lots demand base preparation most flat-lot city jobs never see. Call (866) 253-5808 for a straight answer on your paver project.
Why North Tustin Residents Choose Us for Unilock Service
We’ve been installing and repairing Unilock pavers across North Tustin long enough to know the Brussels Block on one street may sit on completely different soil than the same product three blocks over. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and has spent years watching what happens when a paver base gets shortchanged on expansive clay. That’s why we over-excavate as a rule here. We’re an independent contractor, not a Unilock dealer or authorized installer, and we’ll tell you plainly when a repair makes sense versus when the base is too far gone. Our familiarity with the product line means we source genuine Unilock units and matching edge restraints for repairs so your color blend stays consistent across a partial fix.

Common Unilock Construction Problems We Solve in North Tustin
- Paver “walking” on sloped driveways. North Tustin’s hillside lots put real lateral pressure on pavers, and when the original base wasn’t over-excavated for our expansive clay, edge restraints fail and courses start drifting. We see this constantly on older 1980s and 90s installs where crews used the depth spec for flat ground.
- Polymeric sand loss after Santa Ana winds and rain. Wind-driven debris scours joints, then winter rains wash out whatever sand remains. Once the sand goes, pavers shift and weeds take root. We re-sand with quality aftermarket polymeric blends that hold up to our specific wind and moisture cycles.
- Efflorescence and surface staining on light pavers. When drainage pitches toward the house instead of away, water wicks up through Unilock’s lighter colors and leaves a white chalky bloom. We correct the pitch, not just the surface.
- Settlement and lippage at concrete transitions. Older 1950s through 1970s ranch homes in North Tustin often have original concrete aprons that have already moved. Where a paver driveway meets that apron, we get trip-hazard lippage that needs a proper transition detail, not a bag of sand thrown at it.
- Holding water against the garage slab. If a paver driveway loses its slope over time, runoff pools against the structure. On clay, the base holds that moisture and makes things worse. We re-grade and re-lay the field so water runs to the street.
Unilock Service in North Tustin: What Local Conditions Mean for Your Equipment
Here’s the thing most paver pages never mention: North Tustin has no city hall. When you pull a permit for a new paver driveway or substantial patio here, the file goes through OC Public Works / OC Development Services in Santa Ana, not a municipal building department. For hillside lots off streets like Newport Avenue or La Colina Drive, that often means geotechnical review and a drainage study before the first paver is laid. We’ve sat through those plan checks. The practical result: your base design and grading have to be documented, not eyeballed. You can’t just scrape off six inches and call it good. That’s exactly why we handle the paperwork and the dig, and why we build bases that survive both the inspector and the next twenty Santa Ana wind seasons.
Unilock Models & Products We Service in North Tustin
We install and repair the line consistently across North Tustin’s 92711 ZIP code. Brussels Block and its tumbled, small-format look remains the dominant choice for ranch-style driveways and walkways. Uni-Stone and Holland Stone series show up on older installations and partial repairs where matching matters. Homeowners after a flagstone texture tend toward Beacon Hill. And for drainage-problem lots, the Eco-Priora permeable system is what we recommend when stormwater is pooling where it shouldn’t. We stock common replacement units locally for faster turnarounds on repairs, and we source genuine Unilock product when a color or style has long lead times. Aftermarket polymeric sand and base aggregate we choose for performance, not brand loyalty.

AfterUnilock Service Pricing in North Tustin
Paver work in North Tustin runs a bit higher than Unilock service in Orange and other flat-lot Orange County cities because the clay soil and hillside drainage reviews add excavation and base prep time. Here are the ranges we quote for this market:
| Service | North Tustin Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
The biggest cost driver is always what’s under the pavers. Over-excavating clay, re-compacting in lifts, and correcting drainage costs real money, and skipping it is why so many North Tustin driveways fail within a decade. Our free estimate includes a base assessment and a written line-item quote. Call (866) 253-5808 and we’ll walk the site with you.

FAQs – Unilock Construction in North Tustin
No, because North Tustin isn’t a city. It’s unincorporated Orange County, so permits for a new paver driveway or substantial patio go through OC Public Works / OC Development Services in Santa Ana. Hillside lots often trigger geotechnical and drainage review as part of that process. We handle the permit package and inspections as part of our scope, so you’re not chasing a county counter. Call (866) 253-5808 and we’ll tell you what your specific lot will need.
In North Tustin, the usual culprit is expansive clay under a base that wasn’t over-excavated and compacted to the depth our soil demands. Add Santa Ana wind stripping the joints and rain washing what’s left, and pavers start moving. We see the same pattern on Unilock in Villa Park. The fix is usually re-laying over a corrected base, not just re-sanding. We can assess whether your base is salvageable for a fraction of what a full tear-out costs.
Yes. We source genuine Unilock units that match your existing product and color blend, including Brussels Block, Holland Stone, Uni-Stone, and Beacon Hill. For older installs where the original line has changed slightly, we’ll show you the closest current match before we order anything. Edge restraints and joint sand are matched to what works, not just what’s cheapest.
On North Tustin’s clay-heavy slopes, permeable pavers like Eco-Priora can make a real difference where water currently pools against foundations or runs toward the house. But they only perform if the sub-base is built for infiltration. We’ll give you an honest take: on some of these hillside lots, a properly graded conventional paver system with good drainage is the smarter spend. Call (866) 253-5808 for a drainage walkthrough before you decide.
Light foot traffic is fine the same day. For vehicles, we typically say 48 to 72 hours after the final compaction and joint sand, depending on weather. Santa Ana wind can dry the polymeric sand faster, but we don’t rush it. We’ll give you a clear timeline for your specific project at the estimate.
