Unilock Construction in Lake Arrowhead, CA | Milpitas Construction
Unilock paver and wall work in Lake Arrowhead runs $3,500 – $18,000 depending on scope, and the real challenge isn’t the stone, it’s the mountain. We’re Milpitas Construction, an independent Unilock installer serving Lake Arrowhead, Crestline, and the 92352 ZIP. Ken Stafford runs our crew, and what separates our Unilock work here is simple: we plan every base, drain, and paver choice around Arrowhead Lake Association design review and San Bernardino County slope rules before we excavate anything. Call (877) 752-4194 for a free estimate on paver driveways, patios, and retaining walls.
Why Lake Arrowhead Residents Choose Us for Unilock Service
Most Unilock failures we see in Lake Arrowhead aren’t paver failures. They’re base failures. The pavers do their job; the ground underneath didn’t. Ken learned that lesson early on hillside jobs around the Bay Area, where soil shifts punish shortcuts. He brought the same “no callbacks” standard here from Unilock repair in Running Springs work, and it holds up at 5,000 feet just as well.
We install Unilock Brussels Block, Cambridge Pavingstones, Pisa2, and Estate Wall systems on slopes, driveways, and lake-view patios across Lake Arrowhead. We use genuine Unilock pavers and wall blocks for repairs so color and dimension match the original install. That matters when the ALA has already approved a specific palette and you can’t just swap in whatever’s on the shelf at the nearest big-box store.
If you search for Unilock sales & service, you’ll find plenty of companies that sell pavers. We’re one of the few that also knows what Lake Arrowhead’s terrain does to them after three winters.

Common Unilock Construction Problems We Solve in Lake Arrowhead
- Freeze-thaw heaving on Brussels Block pavers. Lake Arrowhead’s winter cycles freeze water under the pavers, expand it, melt it, and repeat. If the base is just a few inches of sand over native soil, the pavers lift, crack, and spall. We excavate deep enough for a compacted aggregate base and geotextile separation, then re-lay the pavers so they stay flat through the next thaw.
- Efflorescence and joint sand loss on Cambridge Pavingstones. Snowmelt pulls minerals to the paver surface, leaving that white chalky film. Deicing salt makes it worse and breaks down polymeric sand. We address drainage so water doesn’t pool under the surface, then re-sand and seal the joints.
- Settlement and rotation of Estate Wall blocks on slopes. Lake Arrowhead has dozens of hillside lots with 30 – 40% grades. Without geogrid reinforcement and proper drainage behind the wall, blocks rotate outward within a season or two. We rebuild with the right grid depth and a clear path for water to get out.
- Paver migration over old redwood deck footings. A lot of 1950s – 70s Lake Arrowhead cabins had redwood decks that rotted or settled. When pavers go over those old pier locations, they drift. We pull the rotted footings, compact the fill, and install a proper edge restraint so Pisa2 pavers don’t wander toward the slope.
- Driveway edge failure on snow-plowed surfaces. Plow blades catch paver edges and pop them loose. A reinforced concrete or aluminum edge restraint, set slightly below grade, fixes it. We see this on driveways all over Lake Arrowhead after the first heavy winter.
Unilock Service in Lake Arrowhead: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on a generic Unilock page: the Arrowhead Lake Association requires design review for any hardscape that’s visible from the lake or from neighboring properties. That means your paver color, pattern, and even edge treatment may need to match an approved palette before we can dig the first base course. On a steep lot off Kuffel Canyon Road we replaced a failing 1970s redwood deck with a Unilock Brussels Block patio and Estate Wall retaining system. The original pier foundations had settled, so we re-leveled with helical piles, added geogrid, and cut a drainage swale to move snowmelt away from the slope. ALA approved the charcoal-and-sandstone blend after we supplied mock-up photos. That pre-approval step doesn’t exist in most mountain towns, but in Lake Arrowhead it’s part of the job. We handle it so homeowners don’t get stuck mid-project with a palette they can’t change.
Unilock Models & Products We Service in Lake Arrowhead
Our Unilock work in Lake Arrowhead covers the product families most common on mountain properties: Brussels Block, Cambridge Pavingstones, Pisa2, and Estate Wall. For repairs, we insist on Unilock OEM pavers and wall blocks. The color blends are factory-controlled, and aftermarket copies fade differently within a season. Base materials, geogrid, and polymeric sand are quality aftermarket products chosen for freeze-thaw performance at this elevation. We recommend full replacement only when more than 20% of the surface shows structural failure or the base has lost integrity. Otherwise we repair in place, which keeps ALA-approved colors intact and saves you a full design review cycle.

FAQs – Unilock Construction in Lake Arrowhead
No. San Bernardino County and the Arrowhead Lake Association both require geotechnical and drainage review for hillside work on significant slopes, especially where hardscape replaces an existing deck or sits on 30 – 40% grade. We won’t move forward on that kind of project without the report. It protects the slope and your investment. Call (877) 752-4194 and we’ll help you understand what’s required.
Brussels Block pavers hold up well in cold climates, but only with a deep, well-drained base. Lake Arrowhead’s freeze-thaw cycle heaves pavers that sit on shallow or poorly compacted base material. The paver itself doesn’t fail; the base does. We build bases to a depth that handles this elevation’s winter. Call (877) 752-4194 for an evaluation of your current base.
Yes, if your driveway is visible from the lake or neighboring properties. ALA requires color and material submittals before approval. We prepare those submittals as part of the job, which keeps your project moving without a stall at the permitting desk. Call (877) 752-4194 and we’ll tell you whether your site triggers review.
Brussels Block and Cambridge Pavingstones are excellent choices for fire-defensible patios because they’re non-combustible and create a break between your home and surrounding vegetation. Pair them with a clean gravel or concrete edge on the fire side. We spec materials around defensible-space requirements in Lake Arrowhead. Call (877) 752-4194 to talk through your patio layout.
Yes. We lift the settled pavers, re-compact the base, correct the drainage issue that caused the settlement, and re-lay the original pavers. Unless more than 20% of the surface shows structural failure, we repair rather than replace. That keeps most of your ALA-approved palette intact. Call (877) 752-4194 to book a Unilock repair in Muscoy inspection.
