Unilock Construction in San Carlos, CA | Framework Contractors
We provide independent Unilock installation and repair across San Carlos, from paver driveways to retaining walls and patios, and also offer Unilock service in Redwood City. The thing that sets our Unilock work apart here is simple: we engineer the base and drainage for Peninsula clay and hillside slopes before we lay a single block. A flat-lot install that works fine in a neighboring town shifts within a season in San Carlos. Call (844) 681-3590 for a free estimate on Unilock driveways, patios, and walls.
Why San Carlos Residents Choose Us for Unilock Service
Unilock pavers are only as good as what’s underneath them. We’ve installed Unilock pavers and retaining-wall systems on dozens of San Carlos remodels and our Home Remodeling in San Carlos projects, from hillside driveways off Laurel Street to tight backyard patios on post-war lots. We know how Brussels Block, Beacon Hill, Uni-Stone, and Concord Wall behave in Peninsula clay and slope conditions because we’ve watched them perform through wet winters and long dry summers here.
Noel Carbajal, our owner, spent his early years patching stucco and reroofing porches with his uncle before formal training in construction technology. That hands-on background shapes how we approach every job: understand the ground first, then build. We’re an independent Unilock service provider, not manufacturer-affiliated or authorized, which means we source Unilock product directly and pair it with the right geogrid, drainage, and edge restraint for your specific site. See our full Unilock sales & service capabilities. For homeowners throughout the San Carlos service area, that independence means recommendations based on what your lot actually needs, not what a brand rep wants to push.

Common Unilock Construction Problems We Solve in San Carlos
- Paver shifting and settlement on driveways. Expansive clay soils under San Carlos swell in winter rains and shrink in summer. If the original base was cut for flat-lot conditions, you get low spots, lippage, and pavers that rock under wheel loads. We re-excavate, re-grade, and rebuild the base to depth.
- Joint sand loss and edge-restraint failure on sloped driveways. Hillside driveways above the flats put lateral force on edge restraints. When they fail, pavers creep outward and rut. We reset edge restraint with proper spike depth and re-sand joints with the right gradation.
- Efflorescence and surface staining on lighter pavers. San Carlos’s winter rains plus poor drainage away from the house push mineral salts through paver faces. That chalky white bloom on Beacon Hill or lighter Uni-Stone colors is fixable, but drainage has to be addressed or it returns.
- Retaining-wall cracking or bulging on canyon-edge lots. Walls built without enough geogrid or drainage get pushed by uphill surcharge. We rebuild with Unilock OEM blocks and caps, plus proper drainage stone and geogrid layers.
- Failing concrete driveways that need replacing. Many San Carlos homes still have original concrete driveways heaved by clay movement. A Unilock paver driveway on a properly engineered base handles that movement better than monolithic concrete.
Unilock Service in San Carlos: What Local Conditions Mean for Your Equipment
Because San Carlos lots are narrow, built-out, and often slope up from the street, Unilock driveway and patio work here usually starts with an engineered base and drainage plan, not just a paver selection. A flat-lot install that ignores the grade will shift within a season. That’s the reality check every paver job in San Carlos needs. On a hillside lot above Laurel Street, our crew replaced a heaved concrete driveway with a Unilock Brussels Block driveway on a deepened, geogrid-reinforced base and a channel drain at the garage apron. The original flat-lot base had failed against the slope, so we re-graded to shed water and set edge restraint to hold the pavers through the winter rains.
On the flats, where post-war ranch homes sit on roughly 5,000 to 7,000 square foot lots, the challenge is different: tight access, close neighbors, and limited staging. We schedule around that, but the soil under the pavers is still San Carlos clay. Base depth and drainage matter just as much as they do on a hillside.
Unilock Models & Products We Service in San Carlos
We work with the full Unilock product lines you’re likely to have installed or want installed in San Carlos. Brussels Block is the workhorse for driveways and front entries with its tumbled, old-world profile. Beacon Hill gives you a cleaner, more architectural look for modern rebuilds. Uni-Stone remains a solid budget-conscious option for patios and walkways. Concord Wall is what we recommend for retaining walls on sloped lots and canyon edges.
For repairs, we use Unilock’s own OEM retaining-wall blocks, caps, and edge restraints to keep the system’s engineering ratings intact. For geogrid and drainage components, we spec quality aftermarket products where they outperform builder-grade. If a wall or driveway is failing because of base or drainage, not the pavers themselves, we’ll tell you to fix the substructure rather than sell you a cosmetic overlay.

AfterUnilock Service Pricing in San Carlos
Unilock paver work in San Carlos falls into predictable ranges, though your exact number depends on access, slope, drainage needs, and how much excavation the soil demands. Here’s what to expect for the three services most homeowners ask us about:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the cost in San Carlos is the engineering. A flat suburban driveway elsewhere might need six inches of base. A hillside lot above Laurel Street might need twelve inches, geogrid, and a channel drain. That’s not an upsell. That’s what keeps the pavers from shifting. Every free estimate we give includes a site walk, a look at your existing drainage, and a written breakdown of what the base actually needs. Call (844) 681-3590 for your exact number.

FAQs – Unilock Construction in San Carlos
Yes, but only with an engineered base and edge restraint designed for slope. We deepen the excavation, add geogrid where the grade demands it, and set edge restraint with proper spike depth. A flat-lot spec will fail within a season or two. Call (844) 681-3590 and we’ll walk your driveway and tell you what it actually needs.
That chalky white residue is efflorescence, mineral salts pushed to the surface by water moving through the paver. San Carlos’s wet winters plus poor drainage away from the house make it common on lighter Unilock colors. We can clean the surface, but unless we fix the drainage, it comes back next season.
Often, yes. Canyon-edge lots in San Carlos and nearby Emerald Lake Hills Unilock service areas have uphill surcharge that pushes on any patio or wall below. A Concord Wall with proper geogrid and drainage stone is usually the right call. We’ll assess the slope and tell you straight whether a wall is structural necessity or optional.
Expansive clay swells when wet and shrinks when dry, which moves whatever sits on top of it. For Unilock pavers, that means base depth and drainage matter far more than paver style. We excavate to clay-stable depth and build upward with compacted base. That’s the difference between a patio that settles and one that doesn’t.
In most cases, yes. We source Unilock product directly, including older lines like Brussels Block and Uni-Stone, and we match color blends as closely as current production allows. We’ll show you samples on-site before we commit. Call (844) 681-3590 to schedule a match and estimate.
