Unilock Construction in Lake Arrowhead, CA | Polaris Contractors
We provide independent Unilock construction service across Lake Arrowhead, from driveway rebuilds to retaining wall repair, and the thing that sets our Crestline Unilock service apart here is simple: we engineer for snow load, steep grades, and freeze-thaw cycles that most paver installers never plan for. If your Unilock driveway is rocking, washed out, or your wall is leaning after one too many mountain winters, call us at (855) 473-6535 for a free estimate. We’re not a dealer program contractor. We answer to the slope in front of us.
Why Lake Arrowhead Residents Choose Us for Unilock Service
Most paver contractors in Southern California build for flat lots and mild winters. Lake Arrowhead is neither of those things. At roughly 5,000 feet, your pavers and walls take real snow, ice damming, and runoff that moves meltwater fast down steep grades. That changes how a base gets compacted, how edge restraints get anchored, and how drainage gets routed. We’ve been doing full-scope general contracting long enough to know that the prep work under the pavers matters more than the pavers themselves, which is why clients looking for a Lake Arrowhead General Contractor trust us with their mountain properties. Rick Sondermann, our owner, learned the fundamentals of building technology and estimating at Saddleback College and has spent the better part of three decades building and renovating homes up and down the Southern California coast and mountains. That experience shows in how we sequence work and choose materials, especially on second-home properties where the owner may be two hours away. We’re also one team handling everything: hardscaping, roofing, windows, decks, additions, all under one contract. That means your Unilock patio and the drainage around it get coordinated, not cobbled together by three different crews.

Common Unilock Construction Problems We Solve in Lake Arrowhead
- Base and joint-sand washout on sloped driveways. Spring meltwater from snowpack channels down the grade and pumps fines out of the open-graded base, leaving pavers rocking and rutted. We rebuild the base with proper compaction and drainage so it survives more than one melt season.
- Lateral creep and edge failure on driveway aprons. A plastic edge restraint alone can’t hold a slope load once freeze-thaw cycles start heaving the ground. We install anchored restraints sized for the actual grade, not what’s cheapest at the supply yard.
- Efflorescence and salt bloom on darker Unilock pavers. Road salts and de-icers work into the joint sand over winter, then moisture migrating through the units leaves white chalky deposits. We remove the bloom and re-sand with a polymer that stands up better to the next freeze-thaw season.
- Retaining wall settlement and batter loss. Saturated hillside soils and tree-root heave lean walls that were built without proper geogrid and drain rock. We rebuild with the right reinforcement and drainage so the wall actually holds the slope.
- Rutted or sunken paver patios. In Lake Arrowhead, many patios sit on fill that was never compacted for mountain weather. Snow load compresses it, and by spring the patio has dips and low spots. We pull the units, re-grade, and compact properly before re-laying.
Unilock Service in Lake Arrowhead: What Local Conditions Mean for Your Equipment
Here’s something you won’t hear from a general paver installer working in San Bernardino or Riverside: a large share of Lake Arrowhead properties are second homes. That means your Unilock driveway or patio often gets scheduled and inspected remotely. The owner isn’t standing on site watching base prep. We send photo documentation of base compaction, geogrid placement, and drain rock installation before the units ever go down, because you may not see your property again until the snow melts. It’s not a favor, it’s how we protect the work. And the terrain doesn’t make it optional. Many homes sit on steep slopes along narrow, winding private roads, and staging materials or getting equipment to the site, especially in winter, is often as big a challenge as the build itself. On a steep private drive off a winding road near the lake, we rebuilt a Unilock Brussels Block driveway with our Highland Unilock service where meltwater had washed the base out and the pavers were rocking on the slope. We pulled the units, re-cut the grade to drain away from the garage, installed a deeper compacted base with a proper edge restraint and drain rock, and re-set the Brussels Block with fresh polymeric joint sand. Then we sent the owners base-prep photos, because they only visit in summer. That’s what this market demands, and we’d rather over-document than under-build.
Unilock Models & Products We Service in Lake Arrowhead
We work on the full range of Unilock systems you’ll find on Lake Arrowhead properties. Brussels Block, the tumbled dimensional paver, is common on driveways and walkways and shows freeze-thaw damage faster than most. Beacon Hill, with its flagstone-style profile, turns up on patios and pool decks. Onyx and other Elegance-series large-format pavers are frequent on newer builds. And U-Cara and other Unilock retaining-wall block systems need proper geogrid and drain rock, which we specify for the actual slope. For repairs, we buy genuine Unilock units and matching OEM edge restraints and polymeric joint sand when the system is still current. If Unilock has discontinued a color or profile, we’ll match a quality aftermarket paver that blends with the existing field. Our honest stance: cracked or heaved pavers on a bad base get a full base rebuild, not a cosmetic swap. Re-laying pavers over failed subgrade just buys you one more winter.

AfterUnilock Service Pricing in Lake Arrowhead
What drives the cost on a Lake Arrowhead Unilock job is access, base work, and drainage. A steep drive off a narrow private road takes longer to stage and requires more material handling than a flat suburban lot. A patio over uncompacted fill needs a deeper rebuild. A retaining wall that failed needs geogrid and drain rock, not just new blocks. That said, here are the ranges you’re likely looking at:
| Project | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
A free estimate includes a site walk, a look at the existing grade and drainage, and a straight answer on whether the base can be salvaged or needs a full rebuild. Call (855) 473-6535 and we’ll come out, look at what’s actually going on, and give you a written number.

FAQs – Unilock Construction in Lake Arrowhead
Only if it was built for it from the base up. Pavers on a compacted base with proper drainage and anchored edge restraints handle mountain winters fine. Pavers on a thin base with sand joints and plastic edging will shift, rut, and wash out within a few seasons. We design for snow load and meltwater from the start. Call (855) 473-6535 if you want us to look at what you’ve got before the next freeze.
That’s efflorescence, a salt bloom from moisture migrating through the paver units, plus road salts and de-icers that get tracked onto the surface and worked into the joints. On darker Unilock pavers, it’s especially visible. We clean the bloom and re-sand with a polymer that resists the next winter’s salt load better than standard joint sand.
Yes, but it changes how we stage the job. We plan deliveries for the widest vehicle that can safely turn around at your property, and on the tightest lots we’ll stage materials in smaller lifts rather than drop a full truckload at the curb. It adds time and some cost, and we’ll tell you upfront what the access looks like for your specific road.
Most of the time, yes. A leaning wall usually means the batter was lost, the geogrid was undersized or missing, or the drain rock behind the wall is clogged and saturated soil is pushing the blocks out. You can’t straighten blocks that are already moving. We’ll rebuild the wall with the right reinforcement and drainage, offering Unilock repair in Muscoy and surrounding areas, so it holds the slope for decades instead of seasons.
We do, when a visual match is what the project needs. If Unilock has dropped the color or profile, we’ll source a quality aftermarket paver that blends with the existing field. But if the surrounding pavers are heaved or the base is failing, a cosmetic patch isn’t worth your money. We’ll tell you honestly which one you have. Call (855) 473-6535 for a free on-site look.
