Unilock Construction in Pacifica, CA | San Bernardino Contractors
We’re an independent general contractor installing and servicing Unilock pavers, walls, and hardscape systems across Pacifica. What makes our Unilock work different here is simple: we build for fog, salt air, and coastal-bluff slopes, not for a generic California backyard. Most paver failures in Pacifica start underground, in the base and drainage, and that’s where we focus first. If you’re planning a Unilock paver driveway, patio, or retaining wall in the 94044, call us at (855) 473-5620 for a free estimate.
Why Pacifica Residents Choose Us for Unilock Service
We know Unilock product lines the way a roofer knows GAF shingle specs. Brussels Block, Beacon Hill, Town Hall, and the Techo-Bloc lines all behave differently under Pacifica’s marine layer, and we’ve installed enough of each to know which ones hold their color, resist moss, and stay put on a sloped lot. Ruben Castillo, our owner, came up doing framing and concrete work across the Inland Empire, and he’ll tell you the same thing about pavers that he’ll tell you about a roof: if the base isn’t right, nothing on top of it matters.
We’re Unilock sales & service specialists in the sense that we work with this product daily, but we’re clear about one thing up front: we are not manufacturer-affiliated or authorized. That independence means we recommend what actually works on your property, not what a rep wants moved this quarter.

Common Unilock Construction Problems We Solve in Pacifica
- Corroded edge restraints causing paver migration. Salt-laden onshore air eats standard aluminum and steel edge restraints within a few years. We’ve pulled restraints in Linda Mar that crumbled in our hands. The pavers looked fine from above. Below the surface, the whole border was failing. We replace with corrosion-resistant options and re-anchor the edge properly.
- Efflorescence and moss on paver surfaces. Persistent summer fog means paver surfaces in Pacifica rarely fully dry. North-facing slopes in Park Pacifica and Westview are the worst. White mineral deposits and green moss growth aren’t just cosmetic; they indicate moisture is trapped in the joint sand and working into the paver face.
- Base failure on marine-terrace slopes. Much of Pacifica sits on old coastal terraces with a thin soil layer over weathered rock. Excavating the standard 6-8 inches for a paver base often hits hardpan or sloping bedrock. Contractors who don’t account for this get settling and heaving within two winters.
- Joint sand washout from wind-driven rain. Pacifica’s rain comes sideways. Standard joint sand washes out after one or two big storms, leaving pavers loose and rattling. We use polymeric sand blends specifically rated for coastal exposure, and we check joint depth as part of every service call.
- Deck and balcony pavement failures around older homes. Many 1940s-1970s Pacifica homes have patios and walkways that were built on top of older deck framing. That framing rots from the bottom up because the fog never dries the underside. When a paver patio sits on that, you get a double failure: the framing rots and the pavers drop.
Unilock Service in Pacifica: What Local Conditions Mean for Your Equipment
Here’s the thing most contractors from over the hill don’t understand about Pacifica: we don’t fight temperature swings, we fight water that never leaves. This town gets steady moisture from the marine layer, wind-driven rain off the ocean, and salt spray that travels surprisingly far inland. That combination means every piece of metal in your hardscape, from edge restraints to fasteners to rebar in a retaining wall, needs to be selected for corrosion resistance first. It also means drainage isn’t a nice-to-have; it’s the whole game. On a sloped Linda Mar lot, water will find the path of least resistance through your paver base and take the joint sand with it. We’ve rebuilt installations in this specific neighborhood where the original contractor used inland construction standards and the whole surface started moving within eighteen months.
Unilock Models & Products We Service in Pacifica
We install and service the full Unilock residential paver and wall lines, with the most common Pacifica projects involving Brussels Block, Beacon Hill, and Town Hall pavers. We also work with Techo-Bloc lines when a homeowner wants a different color or texture profile. For repairs, we always evaluate Unilock’s own edge restraints and recommended polymeric sands first, but we’re not afraid to spec a high-quality aftermarket corrosion-resistant fastener or drainage component when it outperforms the standard offering for coastal exposure. Our approach on repairs is consistent: fix the base and drainage before replacing a single paver. In Pacifica, the subsurface conditions dictate everything about long-term performance.

AfterUnilock Service Pricing in Pacifica
What drives cost on a Unilock project in Pacifica is what’s happening below the pavers. A flat, well-drained lot is straightforward. A bluff-adjacent property that needs geotechnical review, deeper excavation, additional drainage, and corrosion-resistant detailing will cost more and take longer. Here’s where typical Pacifica projects land:
| Service | Typical Range in Pacifica |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
Every free estimate includes a site walk, base and drainage assessment, and a written line-item quote. No change orders because we didn’t look at the slope. Call (855) 473-5620 to schedule yours.

FAQs – Unilock Construction in Pacifica
The marine layer keeps paver surfaces damp for months at a time, which accelerates efflorescence and moss growth, while salt air corrodes metal edge restraints and fasteners within a few seasons. That means your installation needs corrosion-resistant edge details and a polymer-modified joint sand specified for coastal conditions. We spec both as standard in Pacifica. Call (855) 473-5620 and we’ll walk your property and tell you exactly what’s corroding and what’s cosmetic.
Yes, in most cases. Pacifica’s coastal bluffs and marine-terrace slopes fall under San Mateo County’s Local Coastal Program, which requires geotechnical review and bluff-setback analysis for any hardscape that adds impervious surface or alters drainage near the edge. This is a layer of review that inland Peninsula cities never impose on a paver patio or driveway. We handle that process as part of the project, working with the geotech and the county so you don’t have to chase paperwork.
For Pacifica specifically, we recommend Brussels Block and Beacon Hill for their surface texture and color stability, paired with a polymeric sand rated for heavy moisture exposure. Town Hall works well for larger format looks, but it needs a properly drained base or it’ll show efflorescence faster. The right answer depends on your lot’s orientation and drainage, which is exactly the kind of question we answer during the free estimate.
In most cases, yes. We always prioritize repairing the base and drainage over simply replacing pavers, because in Pacifica the subsurface conditions dictate long-term performance. If your pavers are still intact and the problem is settling, edge restraint failure, or joint sand washout, we can often rebuild the base, re-anchor the edges, and re-sand the joints without tearing everything out. Call us at (855) 473-5620 and we’ll tell you honestly whether repair or replacement makes more sense.
We grade the base to shed water away from structures, install permeable or slotted drainage where slope concentrates runoff, and use a deeper crushed-rock base than inland installs require. On marine-terrace slopes, we’re also looking at where water enters the soil and how it moves underground through the terrace material. If we’re not moving water away from the base, we’re not done.
