Unilock Construction in Boulder Creek, CA | Seaside Contractors
We install, repair, and re-lay Unilock paver systems throughout Boulder Creek as an independent hardscape crew, not a manufacturer-authorized dealer. The short answer: if your Unilock patio, walkway, or driveway is shifting, holding water, or losing joint sand on a steep canyon lot, call (833) 589-8103 for a free site evaluation. What makes our Unilock work different here is that we build for redwood shade, winter rain, and defensible-space rules most flat-lot contractors never have to think about.
Why Boulder Creek Residents Choose Us for Unilock Service
Glen Sorrento started Seaside Contractors after two-plus decades of watching Peninsula and mountain homes get built, remodeled, and rebuilt, and he’s the first to tell you that a paver patio on a Boulder Creek slope is a different animal than one on a Foster City lagoon lot. We know Unilock’s line well enough to specify it honestly: Brussels Block where you want a tumbled, old-world look, Eco-Priora where the county wants permeable coverage, Thornbury where a cottage feel fits the cabin. We’re not sponsored by Unilock and we don’t get kickbacks to push one product line over another, whether it’s Unilock repair in Brookdale or a new install elsewhere. That independence means we’ll tell you when Unilock is the right call, and when a different base detail or edge restraint will do more for the job than the paver brand itself.
We handle full Unilock sales & service across the Santa Cruz Mountains, from new patio installs to tear-out-and-rebase repair work on older installs. We use Unilock’s own units, edge restraints, and joint materials where the system demands it, and quality aftermarket aggregate and polymeric sand where our wet microclimate calls for it. For Boulder Creek homeowners, that means one crew, one phone number, and a crew chief who’s actually been up Highway 236 more than once.

Common Unilock Construction Problems We Solve in Boulder Creek
These are the failure patterns we see again and again on Boulder Creek properties:
- Base failure and downhill migration on steep lots. Pavers don’t fail on their own; the base under them gives way. On a Boulder Creek slope that wasn’t terraced and properly edged, the open-graded base shifts, and the entire field walks downhill over two or three wet winters. We rebuild the base with compaction and a trenched concrete edge on the slope side, then re-lay the original units where they’re still sound.
- Joint sand washout from heavy winter rain and fog drip. Redwood-shaded uphill lots don’t just get rain; they get sheeting runoff and constant moisture that flushes joint sand out of paver gaps. The fix is often a better surface slope to direct water around the patio, plus a polymeric joint sand that actually sets in our damp microclimate instead of washing out in the first storm.
- Efflorescence and moss staining under the redwood canopy. White mineral streaks and green algae growth on shaded pavers look like product failure, but they’re drainage and exposure issues. We don’t just power-wash the surface; we correct the slope and drainage so the problem doesn’t crawl back before summer.
- Edge restraint creep on soft canyon fill. Many pier-and-post-era Boulder Creek properties have uncompacted ground near the foundation. When a plastic paver edge gets spiked into that soft fill, the whole edge spreads outward over time and the field loses its tension. We trench for a concrete curb or use a deeper structural restraint where the ground calls for it.
- Frost heave in thin-sand-bed installs. Boulder Creek gets occasional freeze events that are rare but real. A paver field set on a thin sand bed over native soil will heave under those conditions; a properly built open-graded base with good drainage won’t hold the water that causes it.
Unilock Service in Boulder Creek: What Local Conditions Mean for Your Pavers
Boulder Creek construction happens in a wildland-urban interface canyon, and the county’s fire-safe and defensible-space rules are enforced more strictly on the narrow Highway 236 corridors than in Unilock service in Ben Lomond or other neighboring mountain towns. What that means for Unilock work: a paver patio or driveway layout often has to be set around footprint and clearance questions that surface mid-project. Glen has walked more than one Boulder Creek property where an older cabin hides an unpermitted redwood addition, and where the county’s fire marshal wants defensible space kept clear before any hardscape crew starts laying units. That’s not a complication to work around; it’s the site-specific engineering problem every honest contractor here has to solve. We don’t pad estimates for surprises we already know to look for. We ask about the addition, check the clearance, and set the patio or driveway where it actually works, not where the original plan neatly fit.
Off Highway 236 in Boulder Creek we re-laid a Unilock Brussels Block patio behind a 1970s redwood cabin where the original install had been set on a thin sand bed over native soil. After two wet winters the units had heaved and walked downhill, and the joint sand was gone. We pulled the units, dug out to a compacted open-graded base, cut a trenched concrete edge restraint into the slope side, and re-set the Brussels Block on the original pallet stock we saved, with polymeric joint sand. The patio now sheds water away from the pier-and-post footings instead of into them. That’s the kind of repair that makes more sense than a tear-out on a lot like this one.
Unilock Models & Products We Service in Boulder Creek
We work with the full Unilock lineup as it applies to mountain residential work: Brussels Block for a tumbled, warm look that suits 1960s and 70s cabins; Beacon Hill Flagstone for an irregular, natural stone feel; Thornbury for a cottage-style paver that reads well on single-wall redwood homes; and Eco-Priora permeable systems like Treo and Courtstone where the county wants stormwater handled on-site. Our approach to parts is simple: we use Unilock’s own units and matching restraints and joint materials where the system depends on them, and quality aftermarket base aggregate and polymeric sand where they perform better in our wet, shaded microclimate. We stock common Unilock unit profiles locally for fast Boulder Creek turnaround, and we’ll tell you honestly if a unit you think is discontinued is still available or worth sourcing.

What drives the cost on a Boulder Creek lot is rarely the paver unit itself; it’s the base work, the access, and the drainage corrections. A steep lot that needs terracing, a trenched concrete edge, and an open-graded base built to handle our winter rain will cost more than a flat suburban patio, and we’ll show you exactly where the money goes on a written line-item quote. We don’t bid low and change-order later. Call (833) 589-8103 for a free estimate; we’ll come out, walk the slope, check the drainage and the clearance, and give you a number that actually holds.

FAQs – Unilock Construction in Boulder Creek
Yes, and it gets built differently than a flat-lot patio. The base has to be open-graded and compacted in lifts, the slope side needs a trenched concrete curb or structural edge restraint, and the field needs enough surface slope to shed water away from the cabin’s pier-and-post footings. We also account for redwood shade when choosing joint sand, because some polymeric sands never fully cure in constant dampness. Call (833) 589-8103 for a site-specific answer; we’ll walk your lot and tell you honestly what it needs.
They absolutely do, and they’re enforced more strictly along the Highway 236 canyon corridors than in some neighboring towns. A hardscape project often has to work around required defensible space, fire access, and clearance lines that aren’t obvious on a quick look at the property. We check for these before we ever specify a layout, which saves you from tearing out a patio the county made you move. Call (833) 589-8103 if you’re unsure whether your project site clears.
We’ve seen this more than once, and the honest answer is that it changes the project. If the addition is inside the county’s clearance or defensible-space zone, the patio or driveway may need to shift, or the footprint question may need to be resolved before any hardscape work starts. We won’t bury the issue and we won’t lay pavers over a problem; we’ll tell you what we’re seeing and work the layout around what’s actually permitted. Call (833) 589-8103 for a straight read on your property.
They’ll fail if the base and drainage under them were never built for Boulder Creek conditions. Unilock units themselves hold up fine; what fails is a thin sand bed over native soil, a plastic edge spiked into soft fill, or a flat surface that holds water against the pavers all winter. We fix that by building for the microclimate: open-graded base, positive slope, trenched edge restraint, and joint sand that actually sets in shade. Call (833) 589-8103 if your patio’s already showing the signs.
Usually yes, but it depends on the road. Some Boulder Creek properties sit up long, winding, single-lane drives where a full semi can’t turn around, and we plan for a smaller delivery or a staged run. We’ve done enough Highway 236 work to know which roads are tight before the truck gets there. Call (833) 589-8103 with your address and we’ll tell you how we’d get material in.
