Unilock Construction in Redwood City, CA | Elmstead Remodeling San Francisco
If you’re searching for Unilock construction service in Redwood City, here’s the short answer: we install and repair Unilock pavers, driveways, patios, and retaining walls throughout Redwood City, and we do it as an independent contractor, not a manufacturer-authorized dealer. What makes our work here different is that we plan every Unilock project around Redwood City’s expansive adobe clay soil, which moves more than most people realize. That’s the difference between a paver job that looks great for two years and one that holds for twenty. Call (831) 480-4497 to schedule your free estimate.
Why Redwood City Residents Choose Us for Unilock Service
We’ve installed and repaired Unilock pavers and walls across hundreds of Bay Area properties, and that experience means we know how Unilock’s concrete products actually behave when they meet Redwood City’s soil and fog. Our full Unilock expertise is available to any homeowner, from single paver replacement to complete driveway rebuilds. Graham Stein, our owner, trained at Los Angeles Trade-Technical College and has spent nearly three decades managing crews across California, so he’s seen what works and what doesn’t when clay soil starts moving under a paver base. We’re not a franchise service line. We’re a local crew that shows up, writes the price before any work starts, and leaves your home cleaner than we found it.
We also carry OEM-compatible Unilock pavers and edge restraints locally, so a repair doesn’t stall while parts ship from the Midwest. For Redwood City homeowners, that means less waiting and a job that gets finished before the next rain.

Common Unilock Construction Problems We Solve in Redwood City
Unilock makes quality concrete products, but Redwood City’s particular conditions stress pavers and walls in ways other climates don’t. Here’s what we regularly diagnose and fix:
- Efflorescence on Brussels Block Sierra and other dark pavers. Redwood City’s wet winters push moisture up through the concrete, and when that water carries minerals from the local adobe clay, it leaves a chalky white film on the surface. We treat the cause, not just the symptom, by improving drainage and sealing with a breathable sealer rated for coastal fog.
- Settling and lippage along paver driveways and patios. Adobe clay shrinks hard during Redwood City’s dry summers and swells in winter, causing paver edges to heave against curbs and foundations. We lift, re-grade, and re-compact the base rather than just tapping pavers back into place.
- Weed and moss intrusion in unsealed joints. Mature street trees and persistent coastal fog keep joints damp in many Redwood City neighborhoods, which invites organic growth between pavers. We excavate the joints, install polymeric sand, and seal where the shade is constant.
- Leaning or bulging Estate Wall installations. On 1950s-era ranch homes with sloped yards, the original base was often under-compacted over expansive soil. We rebuild these walls with proper drainage gravel and geogrid reinforcement.
- Older Hollandstone driveways failing under heavier modern vehicles. Many Redwood City homes were built when one car was the norm. Modern trucks and SUVs place heavier loads on bases that were never designed for them.
Unilock Service in Redwood City: What Local Conditions Mean for Your Equipment
Redwood City’s R-1 zoning allows significant second-story additions, which most homeowners don’t think about until a dumpster and a loaded concrete truck need to cross their existing Unilock driveway. We regularly see clients in the Woodside Plaza area who plan a remodel with a General Contractor in Redwood City, then discover their patio or driveway was never built to carry construction traffic. The pavers themselves are fine. The base underneath wasn’t. So we tear out, excavate deeper, install geogrid, and relay the same pavers, often in a stronger pattern. You don’t see this demand in neighboring Menlo Park or San Carlos, where lot coverage and setback rules differ. In Redwood City, your Unilock surface may need to carry thirty tons before it ever carries your family’s car. We build for that reality.
One job that illustrates the point: our crew replaced a failing paver driveway on a Woodside Plaza ranch home. The original Unilock Hollandstone pavers had settled more than two inches in the adobe clay, cracking the edge restraint. We excavated to twelve inches, installed a geogrid base with proper drainage, and relayed the Hollandstone in a 90-degree herringbone pattern. That driveway now handles the homeowner’s full-size pickup without movement.
Unilock Models & Products We Service in Redwood City
We work with the Unilock lines most common in Redwood City landscapes: Brussels Block for patios and walkways, Hollandstone for driveways, Estate Wall for retaining walls and garden terraces, and Olde Quarry for a more rugged, natural stone look. For replacements, we use genuine Unilock pavers and wall units whenever available, and we match discontinued colors through Unilock’s regional distributor network. For structural repairs, we typically recommend replacing the compromised base and bedding sand rather than surface patching. Redwood City’s expansive clay demands proper drainage and compaction more than new pavers alone. We’re also a resource for broader Unilock sales & service questions, from selecting the right product to planning a full install.

FAQs – Unilock Construction in Redwood City
Can Unilock pavers be installed over Redwood City’s expansive adobe clay without future settling? Yes, but only with a deeper base and proper drainage. We excavate to at least eight to twelve inches depending on the site, install geogrid where the soil movement is significant, and compact in layers. Surface-level paver replacement without addressing the base will settle again in Redwood City’s adobe clay. Call (831) 480-4497 and we’ll walk you through what your specific site needs.
My Unilock Brussels Block patio has a chalky white film. Is that a defect? No. That’s efflorescence, which happens when winter moisture wicks through the concrete and carries minerals from Redwood City’s adobe clay to the surface. We can clean it and apply a breathable sealer so it doesn’t return with every wet winter.
Are Unilock pavers from 20 years ago still available for repair in Redwood City? Often yes. We match discontinued Unilock colors and styles through the regional distributor network. When a true match isn’t available, we’ll source the closest compatible paver and lay out the repair so the transition reads as intentional rather than patched. Call (831) 480-4497 for a free match assessment.
How do we handle a Unilock retaining wall that is leaning on a Redwood City hillside property? We rebuild it. A leaning Estate Wall almost always means the original base was under-compacted over expansive soil, and surface repairs won’t hold on a slope. We excavate behind the wall, install drainage gravel and geogrid, and rebuild with proper batter. The old units can often be reused.
Can Unilock pavers be used for a driveway on a steep Redwood City lot without sliding? Yes, with the right base and pattern. Steeper lots need deeper excavation, a geogrid-stabilized base, and a locking pattern like herringbone. We also add a reinforced edge restraint so the whole system holds as one unit. Call (831) 480-4497 to discuss your slope and get a written price.
