Unilock Construction in Daly City, CA | San Mateo Construction
We provide independent Unilock paver installation, repair, and replacement across Daly City and nearby communities, including Unilock in Colma, and the thing that sets our work apart here is simple: we plan every job for fog, slope, and drainage before we lay a single paver. Unilock makes a solid product, but a paver system is only as good as the base under it, and Daly City’s hillsides punish a rushed base faster than almost anywhere else in the Bay Area. Call (855) 901-7266 to talk through your project, whether it’s a new patio, a driveway replacement, or resetting pavers that have started to drift.
Why Daly City Residents Choose Us for Unilock Service
We’ve worked with Unilock’s Brussels Block, Beacon Hill, Umbriano, and Copthorne lines long enough to know how each one behaves under load, on grade, and in moisture. That familiarity matters in Daly City, where a paver patio off Westmoor Avenue faces a different set of stresses than the same patio in San Mateo, Burlingame, or Brisbane Unilock service areas. The fog here doesn’t just wet the surface; it works into the joints and the base, and it never really leaves. We spec materials accordingly.
Noel Carrington, our owner, grew up a few miles south in the Baywood neighborhood of San Mateo, so he’s spent his whole life watching how coastal moisture and hillside soil interact. He studied construction at Skyline College and has been running residential jobs across San Mateo County for decades. When a Daly City homeowner asks whether their failing paver patio needs a full re-base or just a reset, he walks the site and gives them a straight answer. Our crew handles Unilock as an independent contractor, not a manufacturer affiliate, which means we’re free to tell you what your project actually needs, including when a repair makes more sense than a full replacement.

Common Unilock Construction Problems We Solve in Daly City
- White, chalky efflorescence on paver surfaces. The persistent fog on Daly City’s west-side slopes keeps pavers damp for weeks at a time. Without a properly draining base and the right sealant approach, mineral salts migrate to the surface and form that white bloom. We correct the drainage first, then address the surface.
- Settling and shifting on steep driveways. A lot of Daly City homes sit on serious grade, and an original paver driveway often went in over an under-compacted or too-shallow base. The pavers stay fine while the base fails underneath. We excavate to proper depth, compact in lifts, and re-lay the existing pavers when they’re still sound.
- Root intrusion lifting pavers in older tract-home yards. Daly City’s 1950s and 60s neighborhoods are full of mature trees planted close to patios and walkways. Roots push up through the base, break the interlock, and create trip hazards. We address the root zone and rebuild the affected sections.
- Paver spread at the borders. Original installations often used plain steel edge restraints, and Daly City’s coastal air rusts them out within a few seasons. Once the edge fails, pavers drift outward. We switch to stainless or non-corrosive restraints and re-tension the border.
- Weeds and ant intrusion through failing joint sand. When polymeric sand washes out or was never properly installed, Daly City’s damp climate invites weeds and insects into the joints. We re-sand with an appropriate polymeric product after correcting any underlying drainage issue.
Unilock Service in Daly City: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on a generic Unilock page: Daly City’s west-side slopes sit directly in the path of near-constant coastal fog, so pavers there cycle through wetting and drying almost every day for most of the year. That repeated moisture loading does two things. First, it keeps the base material from ever fully drying, which means a marginal base stays saturated and soft, accelerating settlement. Second, it keeps the paver surface damp, which is exactly what efflorescence and surface spalling feed on. Contractors who installed pavers in Daly City using inland Bay Area assumptions rarely accounted for either. We do. Every Unilock job we design for the hillsides here starts with a base section that assumes saturated subgrade conditions from day one, because that’s what the west side actually delivers. If you live along a slope facing the ocean between Westmoor and Serramonte, this is your reality even when the sun is out everywhere else in the county.
Unilock Models & Products We Service in Daly City
We regularly install and repair Unilock Brussels Block, Beacon Hill, Umbriano, and Copthorne pavers across Daly City’s residential neighborhoods. When the existing pavers are sound, we reset and re-sand them rather than pushing a full replacement; when replacement is warranted, we source genuine Unilock pavers to match the existing footprint and color family. We carry OEM Unilock edge restraints and polymeric jointing sands on our trucks for Daly City jobs, and we source base aggregates locally that meet or exceed Unilock’s spec for drainage under saturated soil conditions. For aftermarket materials, we use the same quality gates we’d use for any engineered paver system: correct gradation, proper compaction response, and a clear drainage path.

AfterUnilock Service Pricing in Daly City
What you’ll pay depends on access, slope, and what we find under the existing surface. Here are the ranges most Daly City Unilock projects fall into:

Slope and excavation depth are the two biggest cost drivers in Daly City. A flat patio in Serramonte needs less base work than a steep driveway off Westmoor Avenue. Our written estimate breaks out excavation, base, geotextile, pavers, restraints, and jointing sand as separate line items, so you know exactly what you’re paying for. Call (855) 901-7266 to schedule a free estimate, and we’ll walk the site and give you a number that holds.

FAQs – Unilock Construction in Daly City
The white chalky film is efflorescence, which happens when persistent fog keeps your pavers damp and mineral salts migrate to the surface. It’s usually a drainage problem as much as a surface problem. We fix it by correcting the base and drainage, then treating the surface and recommending a sealer that suits Daly City’s moisture levels. Call (855) 901-7266 for a site visit and a specific answer for your patio.
Yes, if the base is engineered for the slope. We excavate to proper depth, install a geotextile separator, compact aggregate in lifts, and use stainless edge restraints. We’ve done this on a steep driveway off Westmoor Avenue where a failing Brussels Block installation had heaved from poor original compaction; the rebuilt surface has held through two foggy winters.
Loose pavers with weed growth almost always point to failed joint sand and likely a compromised edge restraint. Once the border lets go, the whole field loses tension and pavers start to wander. We re-establish the edge, re-compact the affected area, and re-sand with polymeric material. If the base is still sound, this is a repair, not a replacement. Call (855) 901-7266 to have us take a look.
They need a sealer specified for constant dampness and frequent wet-dry cycling. The wrong sealer traps moisture under the paver surface and can cause spalling. We recommend products based on the specific Unilock line you have and the exposure of your site. Estimates are free; call (855) 901-7266 and we’ll point you in the right direction.
If the pavers are intact but the surface has settled, you likely need a re-base and re-sand. If the pavers themselves are cracked, spalled, or broken, replacement makes more sense. We evaluate the base, the edge restraints, and the pavers as separate components before recommending anything. Call (855) 901-7266 to schedule a free assessment.
