Unilock Construction in Daly City, CA | Seaside Contractors
Unilock paver work in Daly City comes down to one thing: the base. A paver driveway or patio here sits on windblown dune sand, not stable soil, so the excavation and compaction decide whether the surface stays flat or heaves within two winters. We’re Seaside Contractors, and we provide independent Unilock installation and repair across Daly City’s 94014, 94015, 94016, and 94017 ZIP codes. Call (833) 589-8103 for a free estimate on paver driveways, patios, and retaining walls built for this specific ground. One contractor. Every trade.
Why Daly City Residents Choose Us for Unilock Service
Most hardscape crews treat Unilock like any other paver. We don’t, because Daly City doesn’t let you get away with that. Glen Sorrento, our owner, grew up in Foster City’s Shell Cove neighborhood and studied building construction technology at College of San Mateo before spending more than two decades working projects across the Peninsula. He’ll tell you the same thing on every dune-side job: the paver is the easy part. The base is what you’re really paying for. We lay Brussels Block, Uni-Stone II, and Beacon Hill units the way they need to be laid here: over-excavated, compacted in lifts, and restrained at the edges so wind and shifting sand can’t undo the work. We’re an independent Unilock installer, not authorized by the manufacturer, and we think that’s worth saying plainly. Our warranty is on the hardscape we build, not on Unilock’s paperwork. For a deeper look at our approach, see Unilock sales & service.

Common Unilock Construction Problems We Solve in Daly City
These are the failures we see repeatedly on Daly City properties. Each one ties back to the sand, the wind, or the fog:
- Heaving and sinking driveways over uncompacted dune sand. West of Junipero Serra, we regularly pull up Brussels Block driveways that were laid on shallow, uncompacted sand. The apron sinks, the field rocks, and the owner is left wondering why a “premium” paver failed. The paver didn’t fail. The base was never built. We rebuild it properly.
- Rocking units from wind-eroded joints. Afternoon westerlies drive sand and silt into open paver joints, which erodes the joint material and leaves units loose. On exposed patios, this happens within a couple of seasons. We re-sand with polymeric material and, where necessary, re-set the field.
- Corroded edge restraints from salt-laden fog. Galvanized or low-grade edge spikes corrode quickly in Daly City’s damp, salty air. Once restraints loosen, the entire paver field can spread. We replace them with anchored, corrosion-resistant restraints that hold in wind-driven rain.
- Polymeric sand washing out under wind and rain. Wind-driven rain hits Daly City patios at an angle that flushes out poorly applied joint sand. Once the joints are open, units shift. We apply polymeric sand correctly and, where exposure is severe, recommend sealing.
- Retaining wall blocks on unstable sand. SienaStone and similar block walls need a compacted, level base. On dune-side lots where the sand hasn’t been tied down, walls lean or separate. We rebuild the base and re-set the course.
Unilock Service in Daly City: What Local Conditions Mean for Your Equipment
Here’s the detail that separates Daly City from every neighboring town: the dune-side streets west of Junipero Serra sit on loose, shifting sand that was never properly compacted before the post-WWII tract homes went up. Add the persistent coastal fog and strong afternoon westerlies, and you get a combination that punishes shortcuts mercilessly. A Unilock driveway or patio on this ground lives or dies on how deeply we excavate and compact the dune sand, not on the paver choice. We over-excavate by several inches beyond what a flatland crew would do, compact the subgrade in lifts, and set an open-graded base with anchored edge restraints before the first unit goes down. On a dune-side street west of Junipero Serra, our crew tore out a rocking Brussels Block driveway that had been laid on shallow, uncompacted sand and was heaving at the apron. We rebuilt it from the subgrade up, and it has stayed flat through the wind and fog cycles since. That’s the work that matters here. If you’re outside the immediate area, check our Daly City service area to confirm coverage.
Unilock Models & Products We Service in Daly City
We work with the Unilock lines most common on Daly City homes: Brussels Block for driveways, Uni-Stone II for cobble-style driveways and aprons, Beacon Hill for patios with a flagstone look, and SienaStone block for retaining walls. When an existing paver field is structurally sound, we reset and re-sand rather than tear everything out. We use manufacturer-correct Unilock-compatible units and quality base and edge materials, because on dune sand the base and restraints do the real work. If the base or restraints have failed, repair-in-place just delays the rebuild, and we’ll say so directly. Let’s figure out what the job actually needs, then we’ll talk materials.

FAQs – Unilock Construction in Daly City
A Unilock paver driveway in Daly City typically runs $7,000 to $18,000, depending on square footage, base depth, and how much dune sand compaction the site needs. Driveways west of Junipero Serra often land on the higher end because the sand requires deeper excavation and more structural base work. Call (833) 589-8103 for an exact quote, estimates are free.
No. We’re an independent Unilock installer. We don’t rely on manufacturer authorization for credibility; we rely on years of laying Unilock units on Daly City’s windblown dune sand. Our warranty covers the hardscape we build, not Unilock’s manufacturing warranty. We tell every client that before we start.
Yes. We use Unilock-compatible units and manufacturer-correct base and edge materials. On dune sand, the base and restraints are what keep a paver field stable, so we don’t substitute cheap materials there. If an existing paver field is sound, we reset and re-sand rather than replace.
A typical paver repair, like resetting a rocking section or replacing edge restraints, takes one to two days. A full driveway rebuild with deep compaction and new base material typically runs three to five days. Weather in Daly City, especially fog and afternoon wind, can add a day if we need to wait for joint sand to cure properly. Call (833) 589-8103 and we’ll give you a straight timeline for your specific job.
We work with Brussels Block, Uni-Stone II, Beacon Hill, and SienaStone retaining wall block. If you have a different Unilock line, we’ll assess it on site. The model matters less than the base in Daly City, and we’ll tell you honestly whether repair or rebuild makes sense.
