We install and repair Unilock pavers and retaining walls across Lake Arrowhead, CA, and provide Crestline Unilock service.

Call (866) 253-5808 for a free estimate on Unilock paver driveways, patios, and walls in the 92352 area.
Why Lake Arrowhead Residents Choose Us for Unilock Service
Nelson Fung grew up watching his grandfather haggle over tile prices at the hardware stalls on Broadway in LA’s Chinatown, and that obsession with materials never wore off. At Timberline Contractors, we bring that same scrutiny to every Unilock job in Lake Arrowhead and offer Unilock repair in Running Springs. We’re a full-scope general contractor, not a paver-only shop, so when a Unilock driveway replacement reveals a rotted retaining wall or a bad drainage line, we fix the whole problem under one contract.
Our crew has installed Unilock Brussels Block, Beacon Hill, Richcliff, and U-Cara systems on dozens of Lake Arrowhead properties. We know which edge restraints hold through freeze-thaw, which polymeric sands survive ember exposure, and when a paver should be repaired versus replaced. You get direct answers, not a sales pitch. As Nelson likes to say, “Do it right the first time or explain yourself twice.”
We also carry full Unilock sales & service knowledge for every product line we install, so you’re never stuck waiting on a specialty subcontractor who doesn’t understand mountain conditions.

Common Unilock Construction Problems We Solve in Lake Arrowhead
- Freeze-thaw heaving and joint sand loss. Lake Arrowhead sits at roughly 5,000 feet, and winter cycles of freezing and thawing push pavers upward when the base wasn’t compacted properly. We see driveways and patios across the 92352 ZIP with washed-out joints and edge restraints that have let go. The fix is almost always a rebuilt base, not just new sand on top.
- Snowplow damage and salt spalling. Driveway aprons and street-facing walkways take a beating from plow blades and de-icing salt. Chipped, pitted, and spalled paver surfaces are common on older Lake Arrowhead installs. We match replacement units and re-seal so the repair doesn’t look like a patch.
- Ember-scorched polymeric sand and sealers. During wildfire season, floating embers can scorch lower-grade joint sands and some sealers, leaving the joints weak and the surface discolored. We use Unilock’s OEM joint sand and sealers that are far less prone to ember damage, and we can re-sand and re-seal existing hardscape that’s been compromised.
- Retaining wall bulging on slopes. Monsoon-season rain saturates the soil behind retaining walls on steep Lake Arrowhead lots. Walls that weren’t engineered for saturated soil loads start to bulge or lean. We rebuild with proper drainage behind the wall, not just re-stacking the same blocks.
- Base failure from poor original drainage. Many older Arrowhead cabins have hardscape laid directly on native soil with no drain pipe, no geotextile, and no aggregate base. The paver surface looks fine for a season or two, then sinks and shifts. We excavate and rebuild to spec so water moves away from the structure.
Unilock Service in Lake Arrowhead: What Local Conditions Mean for Your Equipment
Here’s what most paver installers who don’t work in Lake Arrowhead miss: your Unilock hardscape isn’t just a surface. In this town, a paver driveway or patio often has to double as a fire-safe hardscape zone within the county’s 100-foot defensible space requirement. That means the same Unilock surface has to resist ember ignition and stay stable under emergency access vehicle traffic. A flatland installer will lay pavers and call it done. We engineer the base, drainage, and jointing system so the hardscape actually functions as part of your defensible space, not against it. On steep, forested lots off roads like Kuffel Canyon Road, the county fire clearance inspection can trigger deck and stair rebuilds before a remodel permit gets signed off, and the paver surface is often the only flat, traversable area on the property. Get the base wrong, and your fire clearance inspection stalls. That dual role, ember resistance plus emergency access stability, is the single biggest difference between a Lake Arrowhead Unilock job and one in the flatlands.
Unilock Models & Products We Service in Lake Arrowhead
We install and repair the full range of Unilock products in Lake Arrowhead, including Brussels Block, Beacon Hill, Richcliff, and U-Cara wall systems. For repairs, we use Unilock’s OEM edge restraints, joint sand, and sealers so the system stays compatible and any remaining manufacturer warranty isn’t voided. For base materials and drainage components, we use quality aftermarket products that meet or exceed spec. When a paver is cracked or a wall is bulging, we assess whether a localized repair with matching OEM parts will restore performance. If the failure is widespread or base-related, we say so plainly and recommend a full rebuild rather than a patch job that will fail again. We keep common Unilock units and OEM joint materials stocked locally so Lake Arrowhead jobs don’t stall waiting on freight.

FAQs – Unilock Construction in Lake Arrowhead
Yes, but only with an engineered base. On steep Lake Arrowhead lots, we install a geotextile separator, compacted aggregate, and OEM edge restraints, and we often switch to a herringbone pattern for interlock strength. Without those steps, freeze-thaw will creep pavers downhill within a few winters. Call (866) 253-5808 for a site-specific assessment.
Unilock concrete pavers themselves are non-combustible and perform well under ember exposure. The weak points are joint sand and sealers. We use Unilock’s OEM polymeric sand and high-heat-tolerant sealers to keep joints intact and surfaces resistant to scorching. Your paver surface can also serve as part of your 100-foot defensible space if the base is stable enough for emergency access vehicles.
We typically recommend Unilock Brussels Block or Richcliff for Lake Arrowhead driveways that get plowed. Both handle surface abrasion well and allow individual unit replacement if a plow blade does chip an edge. Salt resistance comes down to sealer choice and joint maintenance more than the paver itself. Call (866) 253-5808 and we’ll show you samples and explain the trade-offs.
It depends on slope, size, and whether the work touches the county fire clearance area. Steep lots often trigger grading and drainage review, and any work within the defensible space zone may need to clear fire inspection. We handle the permit process as part of the job. Call (866) 253-5808 and we’ll tell you what applies to your specific property.
A Unilock paver driveway in Lake Arrowhead typically runs $7,000 to $18,000 depending on slope, access, base depth, and drainage work. Steep lots with poor access push toward the upper end. Our written quote is fixed, not an estimate that creeps upward. Call (866) 253-5808 for an exact number on your driveway.
