Unilock Construction in Montara, CA | San Mateo Construction
San Mateo Construction installs, repairs, and replaces Unilock paver driveways, patios, and segmental retaining walls across Montara, CA, and nearby communities like Unilock in Half Moon Bay. We’re an independent Unilock installer – not a manufacturer operation – and what separates our Montara jobs is that we build base, drainage, and edge details for a coastal fog belt, not a catalog spec sheet. If your patio is settling or your driveway is pumping joint sand, call (855) 901-7266 for a free estimate.
Why Montara Residents Choose Us for Unilock Service
Unilock’s dimensionally consistent, high-density concrete is one of a few paver systems that actually holds up in Montara’s salt fog and wet soils. We’ve built enough paver driveways and patios along this stretch of coast — from Montara to Unilock in Pacifica — to know exactly which Unilock lines perform and which details fail first. Our crews work exclusively with Unilock because that consistency matters when you’re setting thousands of units that need to stay true through years of marine moisture.
Noel Carrington grew up in San Mateo County and spent three decades working residential and light commercial jobs across the coast. He’s known for tight base work, clean permit packages, and job-site organization that keeps a project moving without drama. When you call us about a settled Brussels Block driveway or a retaining wall that’s leaning, you’re talking to people who have pulled apart failed coastal paver jobs and rebuilt them correctly. We source genuine Unilock pavers and matching wall units so color and dimensional tolerances stay consistent, and we specify stainless or polymer edge restraint and joint sand rated for wet coastal cycles. For Montara homeowners, that’s the difference between a paver system that lasts 20 years and one that starts failing in five.

Common Unilock Construction Problems We Solve in Montara
- Efflorescence and salt-staining on Brussels Block and Beacon Hill pavers. Montara’s marine layer keeps paver surfaces damp through long stretches of the year, and the salt in the onshore wind works into the concrete pores. You’ll see a white, chalky film that never really dries. We clean it and, more importantly, adjust the drainage and joint-sand strategy so moisture stops wicking up from the base.
- Joint sand washout and paver settlement. Coastal soils in Montara stay saturated much longer than inland San Mateo County, and when base compaction or drainage was under-built, the paver field starts to shift. You’ll see sand washing out of the joints after every wet season, followed by low spots and rocking pavers. We pull the affected field, re-grade and re-compact the base with a free-draining aggregate, then re-lay the pavers with polymeric sand that locks the joints.
- Rust bleed and edge restraint failure. The galvanized hardware and aluminum edge restraints used on standard paver jobs oxidize fast in salt-laden wind. You’ll notice rust staining at paver edges and restraint fasteners that have corroded loose. We spec stainless steel edge restraint and non-corroding connectors on every Montara job because we’ve seen what a couple of wet winters do to standard hardware.
- Moss, algae, and organic staining in shaded joints. North-facing patios and walkways in Montara sit in fog-belt shade most of the year, and the constant damp means moss and algae colonize paver joints quickly. We clean and re-sand with a product that resists organic growth, then adjust grading so water doesn’t pond in shaded areas.
- Tight Mid-century footprints that make paver layout awkward. Montara’s housing stock runs heavily to mid-century and older single-family homes with smaller, angled lot lines. Laying larger-format pavers in those spaces wastes material and creates odd cuts. We’ll often recommend smaller course patterns or mixed-size layouts that suit the existing footprint without making the paver field look patchy.
Unilock Service in Montara: What Local Conditions Mean for Your Equipment
Montara’s fog belt keeps paver surfaces wet long after rain ends, so the joint sand and base drainage we build for a Unilock patio or driveway here has to manage constant moisture – not just storm runoff the way an inland San Mateo County job would. That’s the single biggest difference between paving in Montara and paving in, say, Belmont or Foster City, and it’s the reason a generic paver installation spec gets the base wrong. The persistent marine layer means your paver base never really dries out between fog cycles. If the base aggregate doesn’t drain freely, water sits against the underside of the pavers and pushes joint sand out through capillary action every time the fog rolls in. We build Montara bases with a free-draining aggregate and a slight cross-slope that sheds water continuously, not just during storms. On a hillside lot off Kanoff Street in Montara, a homeowner’s Brussels Block paver driveway had settled and was pumping joint sand after years of fog-damp base saturation. We pulled the affected field, re-graded and re-compacted the base, re-set the Brussels Block, and finished with polymeric joint sand and stainless edge restraint so the salt air couldn’t rust the fasteners loose. The driveway now sheds water and holds its joints through the wet season.
Unilock Models & Products We Service in Montara
We install, repair, and extend the Unilock product lines most common in Montara for driveways, walkways, patios, and retaining walls. Brussels Block – the tumbled, dimensional paver found on hundreds of Montara driveways and entry walks – is a staple. Beacon Hill flagstone-style pavers cover a lot of coastal patios and garden paths. For vertical work, we handle Uni-Decor wall block, Pisa2 retaining walls, and the Treo and Estate Wall segmental retaining systems. On every repair or addition, we source genuine Unilock pavers and matching caps so color and dimensional tolerances stay consistent with your existing hardscape. We know the aftermarket paver problem: off-brand “matches” that shift color within a year in Montara’s UV and salt exposure. We don’t use them. What we stock locally for fast Montara turnaround: Brussels Block in the most common Montara color blends, assorted Beacon Hill units, and edge restraint and polymeric joint sand rated for wet coastal cycles.

AfterUnilock Service Pricing in Montara
Here’s what you can expect for Unilock work in Montara. These are the price ranges we quote for the most common paver projects. The final number depends on square footage, base condition, site access, and whether we’re re-using existing pavers or installing new.
| Service | Price Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives the cost on a Montara job: base depth and drainage. If the existing base is saturated and failed, we’re removing and re-compacting – that’s labor and aggregate. If it’s a fresh install, the free-draining base and stainless edge restraint cost more upfront than a standard inland spec, but they’re the difference between a one-time build and a paver field that needs re-setting every few years. A free estimate from us includes a written, line-item quote, and we’ll tell you honestly whether a repair makes sense or a full teardown is warranted. Call (855) 901-7266 to set one up.

FAQs – Unilock Construction in Montara
Yes, but only if the base and joint details are built for it. Unilock’s high-density concrete resists salt and moisture better than most pavers on the market, but the system fails at the joints and edges when the base holds water or standard galvanized fasteners corrode through. We build Montara paver bases with free-draining aggregate and finish with stainless or polymer edge restraint and polymeric joint sand rated for wet coastal cycles. Do that, and a Unilock driveway or patio will stay true for decades. Call (855) 901-7266 for an exact quote on your project.
Because your paver base is staying wet between fog cycles, and the sand is being pushed out from underneath. Standard joint sand doesn’t bind, and when the base holds moisture – very common on Montara’s older paver jobs – every fog cycle wicks more sand to the surface. We fix it by pulling the paver field, re-grading and re-compacting the base with a free-draining aggregate, then re-setting the pavers with polymeric joint sand that locks in place and resists washout. If you’re tired of re-sanding every spring, call (855) 901-7266 for an assessment.
Yes, on every Montara job. Galvanized and standard aluminum edge restraints oxidize fast in salt-laden onshore wind, and once the restraint corrodes loose, the outer paver course starts drifting. We specify stainless steel edge restraint and non-corroding connectors as a matter of course here, not as an upgrade. It’s the detail that keeps the paver field locked in place through years of wet winters.
We can, provided the existing pavers are still available from Unilock in the same color blend. Brussels Block is one of Unilock’s longest-running lines, and we stock the most common Montara color blends locally. For older installations, there can be slight color variation from UV and salt exposure over time, but we source genuine Unilock units so the dimensional match is exact. We’ll bring samples to your property and confirm the match in daylight before we order.
A Unilock paver patio in Montara typically runs $3,500 to $11,000, and a paver driveway runs $7,000 to $18,000, depending on square footage, base condition, and site access. Driveway replacement (removing and re-laying an existing driveway) runs $5,000 to $14,000. The coastal base details – free-draining aggregate and stainless restraint – add some cost over an inland spec, but they prevent the settlement and joint-sand failures that are so common here. Call (855) 901-7266 for a free, line-item estimate. We’ll measure, assess the existing base, and give you a firm number, not a range you have to decode later.
