Unilock Construction in Millbrae, CA | Ashford Contractors
We install and repair Unilock segmental pavers, driveways, patios, and retaining walls across Millbrae as an independent Millbrae General Contractor, not a manufacturer-authorized dealer. The single biggest factor shaping Unilock work in Millbrae is that the city is nearly built-out: most jobs happen on narrow postwar lots where a side-yard setback of three or four feet dictates the entire design. Call (877) 752-3868 to talk through your project. We install Brussels Block, Beacon Hill, and Uni-Decor systems on Millbrae’s flatlands and hillside edges, and we read grade, drainage, and lot-coverage limits before any paver is set.
Why Millbrae Residents Choose Us for Unilock Service
Most Millbrae homes are 1940s to 1960s ranch and stucco builds on small, narrow parcels. The original driveways and side paths on those lots were rarely built with the base depth or edge restraint a modern paver system needs. Glen Mossier, our owner, grew up in Foster City and trained in construction technology at Skyline College, where he learned base compaction, drainage mechanics, and materials science that shows up on the job site. That background matters here: we see how a Millbrae paver job fails before we start, because we have pulled apart enough heaved aprons and sand-starved joints along these exact streets to know what the fog and wet winters do to them. We’re an independent crew doing Unilock sales & service work, which means we recommend the right system for your lot, not the one a manufacturer rep wants moved this quarter.

Common Unilock Construction Problems We Solve in Millbrae
- Efflorescence bloom and salt haze. Millbrae’s marine fog and wet-dry cycling pull minerals through smooth-faced Unilock pavers, leaving a white, chalky crust. We clean the surface and adjust joint sand and drainage so the problem does not come back every winter.
- Paver shifting and sand-joint loss on driveways. Shallow, poorly drained flatland soils under old Millbrae driveways get over-saturated, and thin base rock lets pavers drift. We remove, re-compact the base with proper aggregate depth, and reset the surface to grade.
- Moss and algae in shaded side yards. North-facing patios and narrow side yards in Millbrae never fully dry under the coastal fog. We re-grade for fall, use joint sand that sheds water, and position drainage so moss does not take over the joints.
- Edge restraint failure on narrow paths. A four-foot side yard leaves almost no room for proper edge restraint. We see pavers migrate outward all the time. We install Unilock OEM-compatible edge restraints tight to the foundation and fence line, where they actually hold.
- Standing water and heaved aprons. When a Millbrae driveway apron was laid without fall toward the street, winter rain pools and pushes pavers. We re-grade the surface with the correct pitch and re-lay the apron so water sheds instead of lifting the stones.
Unilock Service in Millbrae: What Local Conditions Mean for Your Equipment
Millbrae is nearly built-out, which means almost every hardscape project here is shoehorned between an existing foundation and a side-yard setback that is often only a few feet. That fact changes how Unilock in Burlingame and nearby areas gets designed. The side-yard setback, typically three to five feet on the old postwar lots, is what kills most planned patios, paths, or ADU-adjacent hardscape before they start. Access width controls what equipment fits, drainage fall has to be threaded between the house and the property line, and lot-coverage limits can restrict how much of the yard you are allowed to pave. On one narrow lot off the flatlands near downtown Millbrae, our crew pulled out a heaved, sand-starved driveway apron and re-based it with a compacted aggregate section before laying Unilock Brussels Block with OEM edge restraint and polymeric joint sand. The original install had no drainage fall toward the street, so winter rain pooled and pushed the pavers; we re-graded it and the owners got a surface that finally sheds water instead of heaving. Paver selection comes last. Grade, setbacks, and drainage come first. That’s the order that works in Millbrae.
Unilock Models & Products We Service in Millbrae
We install and repair the full range of Unilock paver and wall systems homeowners in Millbrae actually specify. That includes Brussels Block, the tumbled dimensional concrete paver that handles Millbrae’s wet winters well when the base and joints are done right; Beacon Hill, a traditional-style tumbled paver that suits the 1950s ranch aesthetic common across the 94030 ZIP; Uni-Decor, the textured and etched series used on patios and walkways; and Brussels Dimensional plus Estate Wall retaining systems for grade changes on hillside lots near the bay side of Millbrae. We use Unilock OEM-compatible edge restraints, wall caps, and joint sands where the system calls for them, and we stock quality polymeric and aggregate joint sands locally so turnaround does not hinge on a supply shipment. When the pavers are sound but the joints or base are failing, we reset and re-sand honestly rather than push a full replacement. A complete re-lay only makes sense when the base itself has failed, which we determine by pulling a few pavers and checking the section beneath.

AfterUnilock Service Pricing in Millbrae

Base repair is the most common hidden cost on Millbrae jobs. An old flatland driveway with three inches of loose sand under the pavers will shift every winter until we dig it out and re-compact it properly. That costs more up front but stops the cycle of re-sanding every spring. Every estimate includes a written breakdown of base depth, drainage fall, joint sand spec, and edge restraint, so you see exactly what you are paying for. Call (877) 752-3868 to schedule a free estimate.

FAQs – Unilock Construction in Millbrae
Yes, if the base is compacted to the right depth and the surface has proper drainage fall toward the street or a French drain. The heaved driveways we see in Millbrae are usually not paver failures, they are base failures: too little aggregate, no geotextile separation, and water trapped under the pavers. We rebuild the section correctly and the pavers stay put. Call (877) 752-3868 for an exact assessment of your driveway, or ask about our Unilock service in South San Francisco.
Usually, yes, but the width dictates the design. A four-foot side yard leaves no room for wide edge restraints, so we use slim OEM-compatible restraints, a modest fall toward a discrete drain or the property line, and a joint sand spec that holds up under continuous shade. It will be a path or a narrow seating strip, not a full patio, but it can be done cleanly and it can last. Call (877) 752-3868 and we will measure your exact setback.
That is efflorescence, the mineral bloom that Millbrae’s marine fog and wet-dry cycling pull through concrete pavers. It is common on smooth-faced Unilock lines like Uni-Decor. We clean the surface with the right process and then address the moisture source: joint sand, drainage, and sometimes a breathable sealer, so the bloom does not return every season. Call (877) 752-3868 for a free quote on the clean-up and re-sand.
Patio and driveway work typically triggers Millbrae’s zoning rules on lot coverage and impervious surface, and some projects do require permits, especially when drainage is rerouted or the paved area expands past the original footprint. On a nearly built-out lot, adding hardscape can push you against the lot-coverage limit faster than you would expect. We check those numbers before any paver is ordered. Call (877) 752-3868 to talk through your specific lot.
It depends on the paver line and the exposure. Sealing can slow efflorescence and moss on shaded Millbrae patios, but the wrong sealer traps moisture under the surface and makes the problem worse. For tumbled lines like Brussels Block, a breathable sealer helps; for smooth-faced lines, we often recommend waiting a full season to let the pavers cure before sealing. Call (877) 752-3868 and we will tell you what your specific paver surface needs.
