Unilock Construction in San Mateo, CA | Bradford Remodeling Co San Francisco
We provide independent Unilock paver installation and repair across San Mateo, from flat Eichler tracts to steep hillside streets off Alameda de las Pulgas. The thing that separates our Unilock work here from any other contractor’s is simple: we’ve spent years watching how serpentine soils move under these pavers, and we build bases and edge restraints accordingly. Call (831) 610-5598 for a free estimate on any Unilock project.
Why San Mateo Residents Choose Us for Unilock Service
Unilock pavers are not a one-size-fits-all product. They perform differently on a fog-soaked Aragon courtyard than they do in a sunny Baywood backyard, and they sure don’t behave the same on a hillside off Alameda de las Pulgas as they do on flat ground. Our crews have been diagnosing and rebuilding Unilock paver systems across San Mateo’s hillside and Eichler developments for years, from failing edge restraints to frost-heaved walkways. We know how Courtstone settles, how Brussels Block wears, and when Richcliff has been chewed up by coastal wind and UV. Curtis Lane, our owner, keeps a worn copy of the California Building Code on his desk and reads more of it than most people would believe. His construction background from Los Angeles Trade-Technical College means the scope documents are tight and the numbers are real. Our Unilock sales & service experience runs deep, and so does our knowledge of the soil under it.
We’re an independent General Contractor in San Mateo, not a manufacturer affiliate. That independence matters because it means our only obligation is to the homeowner in San Mateo, not to a sales quota. Every job gets a written price before work starts. Every completed project carries our 365-Day Done Right Promise in writing. Straight number, real scope, no surprises at close-out.

Common Unilock Construction Problems We Solve in San Mateo
- Edge restraint failure on hillside driveways. Soil creep from the Franciscan Complex’s serpentine rock pushes paver borders outward, especially on steep streets. We pull the border course, reset it on a densified aggregate shoulder, and install rigid PVC edge restraint so the line holds through winter rains.
- Surface erosion and joint sand washout. Fog-drip in summer and heavy winter rain scour the joints in older Brussels Block installations across San Mateo. We re-sand with polymeric compound, which sets firm and resists the wash cycles that keep these patios looking bare.
- Alkali-silica reaction (ASR) microcracking. On 15-plus-year-old Unilock Treo units exposed to saline air rolling in from the Bay, we occasionally find fine cracks across paver faces. It’s uncommon, but when it shows up, we identify it early and replace affected units before they spall.
- Fading and lost surface texture on Richcliff pavers. Baywood and Aragon yards get full sun plus abrasive coastal wind, and Richcliff’s surface finish takes the hit. We replace the worst units and can blend reclaimed matches for discontinued color lines.
- Settling and base failure under driveways. Older San Mateo homes with 1920s-1940s foundations often have paver driveways laid on thin aggregate bases that never accounted for the soil’s moisture-driven expansion and contraction. We correct the base depth and compaction before anything gets relaid.
Unilock Service in San Mateo: What Local Conditions Mean for Your Equipment
Unlike the flatlands of Foster City or the bay-fill neighborhoods of Redwood Shores, San Mateo’s hillside districts overlay the Franciscan Complex’s serpentine rock, which expands and contracts with moisture, creating lateral soil movement that demands deeper compacted base and flexible edge restraints for Unilock pavers. We see this failure most often on steep streets like those off Alameda de las Pulgas. On a 1920s bungalow off El Camino Real in the Aragon neighborhood, our tech found a Unilock Courtstone walkway with edge pavers kicked outward nearly two inches by winter soil expansion in the serpentine-rich clay. We pulled the border course, reset it on a densified aggregate shoulder with a rigid PVC edge restraint, releveled the field, and re-sanded with polymeric joint compound. No full replacement needed, and the line held through the next rainy season. That’s the kind of fix a contractor earns after watching enough San Mateo soil do what it does.
Unilock Models & Products We Service in San Mateo
We install and repair the full Unilock residential lineup: Brussels Block, Courtstone, Treo, and Richcliff. For repairs, we default to genuine Unilock pavers and matching joint sand, because aftermarket color-match and dimensional tolerances often create visible patches that look worse than the damage. When a color blend has been discontinued, we source reclaimed units from Bay Area salvage yards to keep the repair seamless. For fast San Mateo turnaround, we keep the most common paver profiles and joint sands stocked locally, so a border reset or unit swap doesn’t wait on a freight shipment. If base failure is confirmed, we recommend relaying; if the problem is isolated to edges or individual units, we fix what’s broken.

FAQs – Unilock Construction in San Mateo
Serpentine soils expand and contract with moisture, creating lateral movement that pushes pavers outward and opens joints. On flat bay-fill, a standard compacted base usually holds. In San Mateo’s hillside districts, we go deeper on the aggregate base and use rigid edge restraints so the system flexes without failing. If you’re planning a paver driveway or patio on a slope, call (831) 610-5598 and we’ll assess the soil before quoting.
Yes. We source reclaimed units from Bay Area salvage yards for discontinued Unilock color blends, including old Brussels Block and Courtstone lines. The match isn’t perfect out of the box, but we blend reclaimed units into the field so the repair reads as aging, not as patch. Call (831) 610-5598 and we’ll take a look at what you’ve got.
Fog-drip plus UV breaks down the surface pigment and joint sand in Unilock pavers, especially Richcliff units with a textured face. The fog keeps the surface damp while sun bakes it, and the cycle accelerates fading. A proper re-sand with polymeric compound and selective unit replacement restores the look. Call (831) 610-5598 for an exact quote on your patio.
It depends on what’s failing. If edge restraints are shot and joints are open but the base is intact, a border reset and re-sand usually buys you years. If the base has washed out or slab settlement is visible, full replacement with a proper compacted base is the honest answer. We repair individual units and edges before recommending a full relaying. Call (831) 610-5598 and we’ll tell you which lane your driveway is in.
We do. Eichler-era concrete patios in San Mateo were often overlaid with Unilock pavers years ago, and those overlays fail when the original slab shifts or the sand bed erodes under fog cycles. For homeowners considering an upgrade, explore our Kitchen Remodeling in San Mateo. We assess the underlying concrete first, then decide whether the pavers can be reset or whether the slab needs addressing. Call (831) 610-5598 for a free inspection.
