Unilock Construction in San Francisco, CA | Bradford Remodeling Co San Francisco
We provide independent Unilock construction and repair service across San Francisco, from paver patios and driveways to retaining walls. What makes our Unilock work different here is simple: we build for dune sand, fog, and hillside drainage, not just for the product spec sheet. If you’re dealing with sinking pavers or a leaning wall, call (831) 610-5598 for a straight assessment.
Bradford Remodeling Co San Francisco has spent years interpreting how Unilock’s paver and wall systems behave under San Francisco’s adobe clay soils, dense fog cycles, and hillside drainage demands, on top of our daily work as a General Contractor in San Francisco remodeling the Victorians and Edwardians those systems surround. We are an independent Unilock service provider. We are not manufacturer-affiliated or authorized, which means our recommendations come from the field, not a sales deck.
Why San Francisco Residents Choose Us for Unilock Service

Curtis Lane leads our Unilock work in San Francisco, and he brings two decades of hands-on construction experience to every job. He grew up around framing crews, trained in construction technology at Los Angeles Trade-Technical College, and learned how fog-driven moisture moves through older balloon-frame walls during a stretch of gut-and-rebuild projects in the Outer Sunset. That background matters when we’re setting a paver base that has to drain through marine-layer damp for years.
We keep genuine Unilock replacement units on order from our direct regional supplier, so color and dimensional tolerances match the original installation. We work across every San Francisco district, from the Richmond to Bernal Heights, and we show up with a written price before any work starts. Every project carries the 365-Day Done Right Promise: if the work fails inside a full year, we come back and correct it at no charge. That guarantee is in writing, signed, in your hand at close-out.

Common Unilock Construction Problems We Solve in San Francisco
- Lateral drift and bulging in Unilock retaining walls. On steep San Francisco slopes, backfill drains clog with adobe clay fines and water pressure pushes the wall face outward. We see this constantly on hillside lots in Noe Valley and Diamond Heights. The fix usually means rebuilding the wall with proper geotextile and drainage aggregate, not just shoving the blocks back.
- Efflorescence and lichen staining on Brussels Block patios. Persistent marine-layer moisture in the Sunset and Richmond keeps pavers damp for weeks at a time. White mineral deposits and green lichen settle into the surface. We clean and reseal, but we also correct the base drainage so moisture isn’t wicking up from below.
- Rutting and birdbath depressions in paver driveways. Where cars turn on sand-dune lots in the Richmond and Sunset districts, the base compacts unevenly and low spots hold water. We probe for hidden voids, add extra compacted base, and re-lay the pavers so the finished grade sheds water.
- Edge restraint failure on Beacon Hill flagstone patios. Seismic microshifts in San Francisco are enough to kick edge pavers loose when the plastic or aluminum edge restraint wasn’t spiked deep enough. Gaps open along the patio perimeter and the whole field starts to wander. We pull the edge course, reset the restraint, and re-lay.
- Settled Courtstone patios from broken irrigation lines. A slow leak under a paver patio washes away the bedding sand and creates a localized sinkhole. We locate the leak, repair the line, then recompact and re-lay the affected section so it matches the surrounding grade.
Unilock Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco is the only major Bay Area city where Unilock paver driveways in the Richmond and Sunset districts routinely sit on ancient sand dunes. That’s not a footnote; it’s the single biggest variable in whether your hardscape stays flat. Dune sand migrates, it compacts unevenly, and it hides voids that don’t show up until a car tire finds them. So we always probe for hidden voids before we lay a single Unilock unit. We add extra compacted base, typically 4 to 6 inches more than the standard cross-section, and we run a plate compactor in lifts. East Bay crews often skip that step because they’re working on bay mud or alluvial plain, and the same installation that works in Oakland will settle in the Sunset within two seasons. Our crew got called to a home on 23rd Avenue near Golden Gate Park because a Unilock Courtstone patio had dropped two inches in one corner and the string line showed three pavers tilted toward the house. We pulled the section, found the subsurface heavy with fine dune sand and a broken irrigation line, then dug down to install a geotextile separator, re-compacted engineered base, and re-laid the same Courtstone units after cleaning out efflorescence. The homeowner hasn’t seen a dip since, even through the winter fog.
Unilock Models & Products We Service in San Francisco
We service the full residential Unilock line, with most of our San Francisco work centered on Brussels Block, Courtstone, Beacon Hill Flagstone, and Ledgestone wall units. When a repair calls for replacement units, we default to genuine Unilock pavers from our direct regional supplier so the color, chamfer, and dimensional tolerance match the original field. We’ll spec an aftermarket polymeric sand or geotextile when it outperforms Unilock’s standard recommendation for San Francisco’s drainage profile, but we’ll tell you exactly why before we do it. For walls with failed geogrid or crushed cores, we recommend full rebuild over patching; half-measures on a 45-degree hillside don’t last. This is a core part of our broader Unilock sales & service practice.

FAQs – Unilock Construction in San Francisco
In most Richmond district cases, the problem is fine dune sand migrating under the base, often accelerated by a slow irrigation leak or poor drainage. We expose the section, probe for voids, install a geotextile separator, recompacted engineered base, and re-lay the same pavers so the finished grade matches the surrounding field. Call (831) 610-5598 and we’ll put a string line and level on it before we touch anything.
Replacing an existing driveway surface in San Francisco generally does not require a permit as long as you’re not changing the footprint, grade, or drainage pattern, but adding a new permeable paver driveway or changing the drainage path can trigger review by the Department of Building Inspection. If you’re considering our Kitchen Remodeling in San Francisco alongside your exterior work, we coordinate both trades under one schedule. We pull the permit when one is required and we pass inspection before we call the job done.
Yes, we order genuine Unilock Brussels Block replacement units from our regional supplier and work from the original color code when it’s still legible. If the lot code is gone, we match against the existing field as closely as the manufacturing process allows. New units will read slightly different until they weather, but the dimensional fit is exact. An independent supplier, serving San Francisco directly, is your best option for color and stock consistency.
Leaning almost always means water pressure behind the wall. San Francisco’s adobe clay fines clog the backfill drains, water builds up, and the wall face starts to drift. We rebuild the wall with proper geogrid, a geotextile filter, and clean drainage aggregate behind the block. We don’t patch leaning walls because a patched wall on a 45-degree slope will lean again.
Yes, with the right base and drainage. Unilock pavers perform fine in fog-wet conditions, but expect efflorescence and lichen stain over time if the base doesn’t drain. We build with extra compacted base, a geotextile separator, and a slight slope to move water off the field. That keeps the patio flat and dry through the foggiest months. Call (831) 610-5598 for an exact quote; estimates are free.
