Unilock Construction in Las Lomas, CA | Timberline Contractors
We provide independent Unilock paver and retaining wall construction across Las Lomas, from paver patios and driveways to wall systems and step units. What makes our Unilock work different here is simple: we build on clay, not paper. Las Lomas sits in unincorporated Monterey County on rural parcels where well-and-septic review, fog-driven moisture, and salt-laden air off Monterey Bay all shape how a paver system performs ten years after installation. Call (866) 253-5808 for a free estimate, and we’ll tell you honestly whether your project needs a full tear-out or a reset and re-sand.

Timberline Contractors brings the showroom to the job site, and that includes a working knowledge of Unilock sales & service that most general contractors in this ZIP code simply don’t carry. Nelson Fung grew up learning materials from the hardware stalls on Broadway in Los Angeles, and he still treats every paver selection the way his grandfather treated tile: know the substrate before you pick the finish.
Why Las Lomas Residents Choose Us for Unilock Service
We’re not a Unilock dealer trying to move inventory. We’re a licensed general contractor who specifies Unilock because their systems hold up to Pajaro Valley conditions when installed correctly. That distinction matters more in Las Lomas than it does ten miles north. Fog sits on the valley floor for weeks at a time. Winter rain pushes clay soil to swell and settle. Salt air from Monterey Bay works its way into mortar joints and paver surfaces. The contractor who installs a paver patio and skips Unilock repair in Watsonville drainage planning might get away with it. The contractor who does that off a Las Lomas side road doesn’t.
Nelson Fung spent years on jobs across the LA basin before settling into the kind of contractor work he does now: the guy neighbors call when they want someone who will actually explain why one substrate choice matters more than the finish on top of it. That’s the person you’ll talk to when you call about Unilock work in Las Lomas. He’ll tell you where a cheaper base aggregate makes sense and where it will cost you twice as much in three years. Do it right the first time or explain yourself twice.

Common Unilock Construction Problems We Solve in Las Lomas
- Efflorescence bloom and salt staining on Brussels Block pavers. Monterey Bay salt-laden air and the fog-to-sun wet-dry cycle pull minerals through the paver face. We see it most on gray Brussels Block, which shows bloom more than tumbled or colored units. A proper joint sand and drainage plan reduces how often you’ll fight this, but when it appears, we clean and recondition rather than replace.
- Base failure from fines pumping under clay. Las Lomas soil is not forgiving. Winter rain saturates the upper clay layer, and a thin aggregate base lets fines migrate upward, so pavers heave and settle unevenly. We rebuild the base with proper compaction and depth for the soil we actually find, not the soil a spec sheet assumes.
- Edge restraint failure on soggy infill lots. When a paver patio or walk was laid tight to a pre-code ranch home’s foundation, runoff holds water against the wall and the edge restraint pops. We reset the field with Unilock’s own edge restraints and re-grade so water sheets away from the structure.
- Wall block movement on Beacon Hill-style systems without full geogrid tie-back. We see retaining walls on ranch parcels where the geogrid wasn’t tied far enough back into unengineered soil. The wall starts to lean and the caps open up. We reset and rebuild with proper tie-back depth for the slope and soil.
- Mortared joint cracking on SienaStone and Onyx wall systems. Damp winters and salt air accelerate joint failure in mortared applications. We repoint and, where the wall allows, convert to dry-stack with drainage behind the face to stop the same failure from returning.
Unilock Service in Las Lomas: What Local Conditions Mean for Your Equipment
Here’s the thing nobody tells you about building with Unilock pavers in Las Lomas until you’re standing in the permit office. Because this is unincorporated Monterey County and many lots are rural parcels with well-and-septic review, a paver driveway or patio on a ranch outbuilding frequently needs county approvals for grading and drainage before a single course can be set. Pajaro Unilock service areas like Watsonville’s city permit process don’t impose the same burden. A paver driveway on a Las Lomas ranch parcel can trigger a drainage review that asks where stormwater goes when you replace six inches of percolating soil with an impervious paver surface. We handle that paperwork with you, pull the permits, and schedule the work so the county’s review cycle doesn’t stall your project for months. The paperwork, not the rain, is what can delay a Las Lomas job.
On a fog-belt ranch lot needing Unilock repair in Corralitos conditions, we once reset a heaved Brussels Block walk off a Las Lomas side road where the original base had been laid too thin over clay and the pavers were holding water against the house. We pulled the field, re-graded with proper compacted aggregate and Unilock edge restraint, reinstalled the sound pavers, and re-sanded the joints so runoff now sheets away from the older single-story ranch wall instead of pooling at the flashing. The pavers were fine. The base was the problem. That’s the kind of thing that makes a ten-year paver patio out of a three-year one.
What to Look For When Choosing a Unilock Contractor in Las Lomas
Ask whether the contractor has done paver work on a county-permitted rural lot in this ZIP code, not just a tract home in a city. Ask whether they know the difference between Unilock’s OEM edge restraints and whatever the local supply yard has on the shelf. Ask whether they’ll rebuild a failed base or just sell you a full replacement. We answer all of that before we quote, because a Las Lomas paver job is a different animal than a Monterey subdivision job.
Unilock Models & Products We Service in Las Lomas
We build and service the full range of Unilock hardscape systems, including Amesti Unilock service, commonly specified in the Pajaro Valley. Brussels Block and Brussels Dimensional pavers for patios and walkways. Beacon Hill and Onyx wall systems for retaining and garden walls. SienaStone step units for grade changes and entry landings. U-Cara modular retaining wall systems where the wall needs to hold a real load without looking like a highway project. For parts and matching, we use Unilock’s own edge restraints, joint sand, and wall caps, because the system depends on matched profiles and drainage. Base aggregate, geogrid, and drainage fittings come from quality regional suppliers, not from a box store. When a paver field is sound and only the base or edge restraint failed, we reset and rebuild rather than tear out and replace the whole patio.

AfterUnilock Service Pricing in Las Lomas
Here’s what Unilock paver work costs in the Las Lomas area, and what drives the number.
| Service | Typical Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives the cost on a Las Lomas job is almost always the base. Clay soil means deeper excavation and more compacted aggregate than a sandy-lot job in town. County grading and drainage review adds time and sometimes engineering. Salt-air exposure means we spec joint sand and sealer to reduce efflorescence. Your free estimate includes a walk of the site, a compactor test of the soil if we can, and a written line-item quote. No change orders because we missed something in the bid. Call (866) 253-5808 to schedule yours.

FAQs – Unilock Construction in Las Lomas
No. We’re an independent general contractor who builds with Unilock systems regularly, and we specify their products where they fit the site and the client’s budget. We’re not manufacturer-affiliated, which means we recommend the right Unilock series for your specific Las Lomas lot rather than steering you toward whatever’s sitting on the rack.
Yes, and this is exactly the situation where Las Lomas’s county review process matters most. A retaining wall or paver field near a septic leach line or well head can trigger Monterey County review that a city project never sees. We schedule the percolation test and septic/well approvals first, then design the wall and drainage around what the county will actually sign off on. Call (866) 253-5808 if you have a wall or paver project on a ranch parcel, and we’ll walk the specifics with you.
Edge restraints, joint sand, and wall caps come from Unilock directly, because the profiles and drainage properties are matched to the system. Base aggregate, geogrid, and drainage fittings come from regional suppliers we trust. We don’t cut corners on parts that hold the system together.
A standard paver patio on a prepared base typically runs three to five working days on site. A paver driveway or retaining wall runs longer, and a ranch parcel with county drainage review adds time before we even start. We’ll give you a schedule as part of your written estimate, and we stick to it.
A paver patio typically runs $3,500 to $11,000, and a paver driveway runs $7,000 to $18,000. Those ranges reflect the difference between a simple flat-lot patio and a driveway on clay soil that needs a deeper base and county drainage review. Your exact number depends on what we find on the walk. Call (866) 253-5808 for a free estimate with a line-item breakdown.
