Unilock Construction in Mount Hermon, CA | Timberline Contractors
Mount Hermon General Contractor Timberline Contractors handles Unilock paver installation running $3,500 – $18,000 depending on scope — neighbors call us when pavers start heaving, moss takes over, or a driveway needs rebuilt under the redwoods. We’re Timberline Contractors, and we’ve been installing and repairing Unilock paver systems across the Santa Cruz Mountains long enough to know exactly how these products perform in this specific microclimate. For a straight answer on your project, call (866) 253-5808.
Why Mount Hermon Residents Choose Us for Unilock Service
Unilock makes a genuinely good paver. But a paver is only as stable as the base underneath it, and in Mount Hermon the base is where everything gets interesting. Shallow bedrock, aggressive tree roots, and soil that stays damp nine months out of the year all work against a standard installation. We know the product line, we know the failure points, and we know how to build a base that holds.
Nelson Fung, our owner and general contractor, spent years swinging hammers across the LA basin before Timberline Contractors took root here, and we now offer Ben Lomond Unilock service as well. He’s the guy who will tell you exactly why a geotextile separator matters more than the paver you put on top of it. We’re independent, not affiliated with Unilock, but we source their OEM polymeric sand and edge restraints so your warranty stays intact. What we won’t do is pretend Mount Hermon is like anywhere else.

Common Unilock Construction Problems We Solve in Mount Hermon
- Efflorescence on Brussels Block. Constant fog and poor drainage in shaded lots pull minerals to the surface, leaving that chalky white haze that masks the paver’s intended color. We clean it properly and address the drainage issue so it doesn’t return in six months.
- Moss and algae between pavers. North-facing slopes under redwood canopy rarely see direct sun. Polymeric sand breaks down, moisture sits, and moss moves in. We re-sand with OEM product and recommend a maintenance schedule that actually works for this climate.
- Base settling and lippage. Tree roots push up, shallow bedrock stops compaction, and suddenly your patio has trip hazards. We cut out roots, re-compact with proper aggregate, and re-lay the original pavers when they’re still sound.
- Freeze-thaw spalling on older Copthorne units. Winter moisture penetrates unsealed pavers, expands in cold snaps, and the surface starts flaking. We repair or replace affected units and seal the rest to slow further damage.
- Driveway replacement after root damage. The old mid-century redwood cabins here often have driveways that were never built on a proper base to begin with. We pull them, fix the substrate, and install Unilock units that can handle vehicle loads.
Unilock Service in Mount Hermon: What Local Conditions Mean for Your Pavers
One thing that sets Mount Hermon apart from Scotts Valley or Santa Cruz is the combination of private roads and dense canopy. Paver deliveries here usually require a smaller bobtail truck, not a full semi, because the roads are narrow and the branches hang low. Our crews stage materials carefully, often bringing them in smaller loads to get exactly where they need to go without trimming limbs or blocking conference traffic. Then there’s the fire-safe angle. Mount Hermon sits in a high fire-severity zone, and Unilock’s non-combustible pavers are a genuinely smart choice for defensible space zones around the property. We regularly recommend them for walkways and patios close to the house, where a wood deck would be a liability. Builders used to standard Santa Cruz County codes are often surprised by how much the fire district here cares about hardscaping choices.
We recently rebuilt a failing Brussels Block patio behind a 1950s redwood cabin on Conference Drive, where root intrusion had heaved the base and moss had overtaken the joints. After cutting out the roots and re-compacting with a geotextile separator, we re-laid the original pavers with new OEM polymeric sand and added a French drain to divert runoff from the slope. The homeowner now has a stable, moss-resistant surface that meets fire-safe clearance recommendations.
Unilock Models & Products We Service in Mount Hermon
We install and repair the Unilock product families that make sense for this climate: Brussels Block, Beacon Hill, Copthorne, and Thornbury. Brussels Block remains our most common service call in Mount Hermon and for Unilock service in Felton; it’s a classic paver that holds up well under foot traffic but needs proper base work and drainage to avoid the efflorescence and moss problems this area is known for. For repairs on older installations, we match existing units by color family and texture. When pavers are structurally sound and the base is intact, we repair. When the base has failed, we do a partial replacement with matching units rather than tearing out the whole job. We stock OEM polymeric sand and edge restraints locally for faster turnaround, and for older installations we use aftermarket cleaners and sealers that hold up better in damp shade than what was available a decade ago.

AfterUnilock Service Pricing in Mount Hermon
Most Unilock project costs come down to three things: access, base repair, and the footprint of the job. Here’s what we see across the Mount Hermon market:
| Service | Typical Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives cost up is access difficulty and base failure. A flat backyard patio with easy staging is quick work. A sloped lot with tree roots and a narrow private road takes longer. Our free estimates include a base assessment, so you’ll know how much work is under the pretty part before we ever break ground. For an exact number, call (866) 253-5808.

FAQs – Unilock Construction in Mount Hermon
Yes, but they require base work that most installers skip. On steep, tree-rooted lots in Mount Hermon, we cut intrusive roots, add a geotextile separator to keep new roots from pushing through, and compact the base more aggressively than standard flat-lot practice. The pavers are the easy part. Getting the base right is what keeps them flat for years.
The fix starts with drainage. Moss thrives where polymeric sand stays damp for weeks, so the first step in Mount Hermon is ensuring water flows off the paver surface and away from the low spots. We then re-sand with OEM product and schedule periodic re-sanding. Sealers help, but if the drainage is wrong, a sealer just traps moisture underneath. Start with drainage first, then talk sealer. For a quote on re-sanding or drainage fixes, call (866) 253-5808.
Unilock concrete pavers are non-combustible, which makes them a strong choice for defensible space zones around homes in Mount Hermon’s fire-severity area. Concrete won’t ignite like wood decking or siding, and a paver walkway or patio against the house gives firefighters a clean surface to operate on. It’s one of the few material upgrades that improves both curb appeal and fire safety at once.
You’re looking at $7,000 – $18,000 for a standard Mount Hermon driveway, with the upper end reflecting difficult access, steep grades, or a failed base that requires full excavation. Driveway replacement on an existing failure ranges $5,000 – $14,000. We give fixed written quotes after a base inspection. Call (866) 253-5808 for a free estimate.
Usually, yes. We match by product line, color family, and texture. Brussels Block and Beacon Hill are still in production and easy to source. Older Copthorne runs may have slight color variation, so we’ll bring samples for you to compare before any work starts. If the base under the damaged section is still sound, we repair. If the base has shifted, we fix the base too. A partial replacement with matching units usually beats a full tear-out by a wide margin.
