Why San Francisco Homeowners Choose Unilock Construction
We provide Unilock in San Francisco construction, repair, and installation service, from paver driveways and patios to retaining walls and hardscape features. Bradford Remodeling Co San Francisco works on Unilock paver driveways, patios, and retaining walls across the city’s microclimates, so we diagnose fog-belt efflorescence, clay-soil settlement, and salt-air joint washout from daily field reps, not from a brochure. We are an independent Unilock service provider, not an authorized Unilock dealer or affiliate, which means we answer to you, not to a manufacturer’s sales quota. Curtis Lane owns Bradford Remodeling Co San Francisco, and his crew has been pulling apart failed paver bases and rebuilding them properly throughout the Richmond, Sunset, and West Portal neighborhoods for over two decades. If you have a Unilock surface that isn’t holding up the way it should, call (831) 610-5598 and we’ll give you a straight read on what it needs.
Why Trust Bradford Remodeling Co San Francisco for Your Unilock Construction?
Unilock pavers are manufactured in batches, and color, surface texture, and dimensional tolerance shift slightly from run to run. You can’t just grab any gray paver off a shelf and expect it to match a Beacon Hill Flagstone patio laid six years ago. Curtis learned how to read material specs as a construction technology student at Los Angeles Trade-Technical College, where proper material takeoffs were drilled into him before he ever stepped onto a paying job site. That training shows in the way we handle Unilock work: we check paver dimensions against the existing installation, identify the original product line, and source replacement units by batch when possible. For Unilock Brussels Block driveways, Courtstone patios, and Richcliff walls, we know which structural failures indicate subgrade problems rather than bad pavers. And every Unilock job we complete falls under the same written guarantee as everything else we do: the 365-Day Done Right Promise. If our work fails inside a year, we come back and correct it at no charge. That’s The Garrison Standard, and it’s in writing before the first paver comes up.

Common Unilock Construction Problems We Fix in San Francisco
San Francisco’s climate punishes hardscape in ways that surprise contractors who learned their trade in inland cities. Here’s what we actually see on Unilock installations throughout the city:
- Fog-belt efflorescence on Unilock Beacon Hill Flagstone and Brussels Block. Moisture from San Francisco’s marine layer wicks through the concrete paver and evaporates from the surface, leaving behind white mineral deposits that streak and haze dark paver faces. It’s not a manufacturing defect; it’s moisture chemistry. We remove efflorescence and apply a breathable sealer that slows re-absorption without trapping water in the paver.
- Edge restraint failure from clay-soil heave. Many San Francisco hillside homes sit on adobe clay that expands when wet and shrinks when dry. That seasonal movement pushes against paver edges until the plastic or aluminum edging bows outward and soldier courses tilt. We see this constantly on Unilock Courtstone patios in West Portal and Forest Hill. The fix is deeper than resetting the edge; the subgrade needs drainage correction so the clay stops moving the way it has been.
- Polymeric sand joint washout on hillside patios. Heavy rain on a steep San Francisco lot sends sheet water across paver surfaces fast enough to scour joint sand out from between pavers. Once the joints go, pavers rock underfoot and begin chipping at the corners. Unilock Richcliff patios with their tighter joints resist washout better than wider-joint lines, but no polymeric sand survives standing water. We regrade for positive drainage, then re-sand and compact the joints.
- Color fade on north-facing installations. Pavers on the shadowed north side of a San Francisco home never fully dry between fog cycles. Dark Unilock colors like the charcoal and slate tones in the Beacon Hill line lose their richness faster in these conditions than on sunlit south-facing slopes. We don’t refinish faded pavers with paint or stains; we replace affected units with batch-matched new stock when surface degradation reaches a point where the original color cannot be restored.
- Settlement in sand-dune neighborhoods. Homes in the Outer Richmond and Outer Sunset sit on sand, not clay. Unilock paver driveways out there settle unevenly as wind-blown sand shifts beneath the base. We’ve pulled up Courtstone driveways that had dipped three inches at the garage apron because the original installer skipped the geotextile separation layer. We lift, regrade, add geotextile, and reset the same pavers whenever they’re still structurally sound.
Unilock Parts & Our Repair-vs-Replace Approach
We source genuine Unilock pavers, color-matched by batch, for patch repairs whenever the original product line is still in production. For older Unilock retaining wall systems where the cap unit has been discontinued, we cut and fit locally sourced concrete cap units that match the existing profile and color as closely as the material allows. Here’s how we decide what to fix and what to replace: a single cracked paver in a walkway that isn’t load-bearing usually gets a patch repair. A cracked paver in a driveway path that carries vehicle weight tells us the subgrade moved, and spot-filling is a temporary fix at best. We recommend replacing cracked structural sections when the failure pattern suggests base movement rather than impact damage. And when we write the repair quote, you get a fixed number before any work starts. No shift at the door. Call (831) 610-5598 for an exact quote on your Unilock repair.
Our Unilock Service Process – Step by Step
Unilock work isn’t a mystery. Here’s the process, in order, the way we run it in San Francisco:
- 1
Diagnosis. We come out, look at the failed area, and identify the specific Unilock product line and the underlying cause: drainage, subgrade movement, edge restraint, or paver fatigue. You get a written diagnosis with the repair scope.
- 2
Repair or installation. For patch work, we lift the affected area, correct the base, reset batch-matched Unilock units, and re-sand the joints. For full installations, we excavate to the proper depth for San Francisco’s soil conditions, install the geotextile and crushed rock base, compact in lifts, and lay the pavers to Unilock’s specified joint widths.
- 3
Testing. We run water across the finished surface to confirm drainage direction. We check edge restraint by hand. We look at every joint line. If the water pools, we fix it before we put our name on it.
- 4
Warranty. Every completed job gets the 365-Day Done Right Promise in writing. Clean site, documented scope, signed guarantee in your hand. That’s what squared away looks like at close-out in San Francisco.

AfterUnilock Products We Service & Install in San Francisco
We work across the Unilock product range most common in San Francisco’s residential hardscaping: Unilock Beacon Hill Flagstone for irregular-flagstone patios and walkways, Unilock Brussels Block for classic tumbled driveways and front entrances, Unilock Courtstone for formal paver patios and pool decks, and Unilock Richcliff for contemporary architectural surfaces with tight joints. We keep a rolling inventory of joint sand, edge restraint, and geotextile in our service vehicles for fast turnaround on repairs. For pavers themselves, we order by batch from Unilock suppliers and confirm delivery before we schedule the tear-out so your yard isn’t left open while we wait on material.
Unilock work sits inside our broader General Contractor services and remodeling capability. The same crew that resets a sunken Courtstone patio in West Portal also installs paver driveways, paver patios, and full bathroom remodels under one written scope and one written price.
We Also Service These Brands
Unilock is one brand we know well, but it’s not the only one. We install and service KraftMaid cabinetry, Cambria and Silestone surfaces, and Kohler fixtures as part of our full remodeling scope. Documented brands, documented specs, same written guarantee across every job.
FAQs – Unilock Construction Service in San Francisco
That white haze is efflorescence, not paint failure or paver breakdown. San Francisco’s fog delivers persistent moisture that wicks through the concrete paver and carries dissolved minerals to the surface, where they crystallize as the water evaporates. Beacon Hill Flagstone’s darker colorways make the bloom more visible than on lighter surfaces. We remove it with proper efflorescence cleaners and, where the microclimate calls for it, seal with a breathable product that slows moisture absorption without trapping water. Call (831) 610-5598 for a free estimate on efflorescence treatment.
Sometimes, and we’ll tell you straight when we can’t. Unilock Brussels Block comes out of production runs that vary slightly in tone, and a driveway laid eight years ago will also have weathered. We source batch-matched units from current production and compare them on-site against your existing surface before committing to a patch. When a color match isn’t achievable, we’ll say so and discuss replacement options rather than laying mismatched pavers and hoping you don’t notice.
Leaning in a retaining wall almost always means water is pushing from behind. San Francisco’s clay soils hold water, and when the hillside behind a Unilock wall saturates, hydrostatic pressure builds against the back face. If the original drainage stone and weep holes weren’t installed properly, the wall starts to lean or bulge. We excavate the back side, install proper drainage, rebuild the affected section, and reset the cap. If the wall is old enough that Unilock’s cap unit has been discontinued, we cut and fit locally sourced concrete caps to match.
Plan on inspecting joints every fall and re-sanding as needed, which on steep San Francisco lots usually means every two to three years. Unilock Richcliff’s tight joint profile holds sand well, but hillside sheet flow during heavy rain will still scour joints over time. If you’re re-sanding yearly or seeing sand wash out after a single storm, the problem is drainage, not the sand. We’ll grade the surface so water moves off the paver face instead of across it. Call (831) 610-5598 and we’ll assess your patio’s drainage.
We use genuine Unilock pavers for patch repairs whenever the original product line is still in production and we can source batch-matched units. For discontinued retaining wall caps and specialty pieces, we cut and fit locally sourced concrete units as a practical substitute, and we tell you that’s what we’re doing before we write the quote. No part of our Unilock repair work hides what materials go into the ground.
