Unilock Construction in San Francisco, CA | Elmstead Remodeling
Unilock paver driveways, patios, and retaining walls in San Francisco typically cost between $4,130 and $21,240 depending on scope, and most installations take 3 to 7 working days once we’re on site. What makes our Unilock work different across San Francisco is that we design every base and edge detail around the city’s actual ground conditions: bay-fill soils, persistent fog-belt moisture, and the mandatory soft-story retrofit cycle that keeps pulling driveways back up. We’re Elmstead Remodeling, a Cedarwell company, and we’ve been installing Unilock hardscape here long enough to know what holds up on a Marina District lot versus a Twin Peaks slope.

Why San Francisco Residents Choose Us for Unilock Service
We’re an independent General Contractor in San Francisco, not a Unilock dealer and not manufacturer-affiliated. That independence matters because our recommendations come from watching Unilock products perform on San Francisco soil for years, not from a sales quota. Graham Stein, our owner, learned framing and finish work at Los Angeles Trade-Technical College before spending two decades on residential projects, and he carries that same read-the-plans-first discipline into every paver base we compact. When you call about a Unilock driveway in the Outer Sunset or a patio in Noe Valley, you get a straight answer about what’s under the pavers, what’s causing the problem, and what it’ll cost to fix it properly. We source genuine Unilock paver units and edging profiles when matching existing courses, and we use aftermarket polymeric joint sand and base aggregate that meet or exceed Unilock’s spec for this market. Our crews are background-checked, uniformed, and they show up with drop cloths and shoe covers as a matter of course, not as an add-on.
Every project is governed by the Cedarwell Care Promise: a written price before any work starts, a photo of the clean-up before the crew leaves, quiet tools during family rest hours where possible, and pet-safe product choices where there is one. The written scope is the promise – if it is not on the paper, we have not agreed to it yet. And every completed project carries the 365-Day Done Right Promise. If it’s not done right, we make it right. That commitment has outlasted more than a few San Francisco winters.

Common Unilock Construction Problems We Solve in San Francisco
- Efflorescence bloom on Brussels Block and Beacon Hill pavers. The salt-laden fog that rolls through the Outer Sunset and Richmond districts pulls calcium hydroxide to the paver surface, leaving white chalky stains that recur seasonally unless the pavers are sealed correctly. We clean and seal with a breathable silane-based sealer that lets the paver shed moisture without trapping it.
- Base settlement and paver shifting on bay-fill lots. In the Marina and Mission Bay, the sandy substrate and high water table undermine the open-graded aggregate base that Unilock permeable systems rely on. The pavers themselves hold up fine; the sub-base doesn’t. We excavate deeper, install geotextile fabric, and compact in lifts that account for the liquefaction-prone ground.
- Joint sand loss and edge restraint failure on sloped installations. San Francisco’s winter storm surges and hillside runoff channel water across paver surfaces faster than joint sand can drain. When the edge restraint fails on a slope, the whole field starts to creep. We re-set edges with reinforced restraint and re-sand with a polymeric product that actually holds under flow.
- Frost heave cracking along Pisa2 and Umbriano retaining wall caps. Exposed yards near Twin Peaks get saturated from fog drip, then hit with occasional hard freezes. The freeze-thaw cycle works wall caps loose. We replace caps and re-level the wall course, then improve drainage behind the wall so the next freeze has less water to work with.
- Driveway aprons broken by soft-story retrofit work. When a 1930s fourplex gets its mandatory moment-frame retrofit at the garage level, the concrete apron and any hardscape in front gets demolished to reach the structure. We routinely install Unilock pavers on a removable sand-set base so the driveway can be lifted out and reinstalled when the next phase of inspection passes.
Unilock Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s mandatory Soft-Story Retrofit Ordinance, enacted in 2013 with phased compliance deadlines, requires thousands of older wood-frame multi-unit buildings to add moment frames and shear walls at the ground-floor garage level. That means the driveway apron and any Unilock hardscape in front of that garage is frequently demolished and rebuilt after the structural work, and we now routinely install Unilock pavers on a removable-sand-set base so the driveway can be pulled up again when the next phase of retrofit inspection passes. This is not how we’d build a driveway in Oakland or Daly City. It’s a San Francisco reality, and it changes the base design, the edge restraint, and the paver pattern we recommend. In the Outer Sunset, we rebuilt a 22-foot Unilock Brussels Block driveway for a 1930s soft-story fourplex whose garage-level moment-frame retrofit had cracked the existing concrete apron and undermined the base. We excavated to compacted Class II aggregate, set a permeable open-graded base with edge restraint, laid Brussels Block in a herringbone pattern, and finished with polymeric joint sand. The owner now has a driveway that drains the fog-belt runoff and can be lifted out if the city requires a second retrofit inspection.
This is the page where that connection gets made clearly: San Francisco’s retrofit cycle and bay-fill liquefaction risk change how a Unilock driveway is engineered, which is why a Sunset driveway is built differently from one in a neighboring city. If you own a multi-unit building in a soft-story zone, the paver base under your car deserves as much thought as the shear wall behind the garage door. Our Unilock sales & service experience across retrofit projects means we plan for the next permit, not just the next rain.
Unilock Models & Products We Service in San Francisco
We work with the Unilock product lines that perform best in San Francisco’s conditions. Brussels Block is our go-to for driveway and patio work in the fog belt: its tumbled edges hide wear and its color range suits the city’s older housing stock. Beacon Hill flagstone works well for larger patio surfaces where a more formal look fits a Marina or Pacific Heights property. Pisa2 and Umbriano are the retaining wall systems we see most often on sloped lots, and both see frost heave issues in the hillier neighborhoods. When an existing installation needs matching units, we source genuine Unilock pavers and edging profiles so the repair blends with the original course. On a 15-year-old Brussels Block driveway with intact units, we re-level and re-sand rather than tear out. On a wall with cracked Pisa2 caps and a failed base, honest replacement is cheaper than chasing recurring repairs. We carry the joint sand, base aggregate, and edge restraint profiles locally so San Francisco turnaround doesn’t wait on a distributor across the Bay.

FAQs – Unilock Construction in San Francisco
A Unilock paver driveway in San Francisco typically runs $8,260 to $21,240, while a concrete driveway runs $5,310 to $14,160. The paver premium buys you a removable surface that can be lifted for soft-story retrofit work, better drainage on fog-soaked lots, and individual unit replacement rather than full slab patching. For an exact quote, call (949) 850-9896 – estimates are free.
Yes, but the base has to be engineered for it. Marina District lots sit on sandy substrate and high water tables that liquefied during Loma Prieta, so we excavate deeper, lay geotextile fabric, and compact a reinforced open-graded base before the pavers go down. Skip those steps and the pavers will shift within a couple of wet winters. Call (949) 850-9896 to have us check your specific lot.
Brussels Block is our pick for the fog belt. Its tumbled finish doesn’t show the wear that a crisp-edged paver does, and it sheds the near-daily Outer Sunset moisture well when sealed with a breathable silane sealer. Beacon Hill also performs well, but it benefits from the same sealing treatment. The key is the sealer, not just the stone.
That’s efflorescence. San Francisco’s salt-laden fog pulls calcium hydroxide from the concrete paver to the surface, where it dries as a white bloom. In the Outer Sunset and Richmond, it recurs seasonally unless the pavers are cleaned and sealed with the right breathable sealer. We handle the cleaning, the sealing, and the prep so the bloom doesn’t come back next summer. Call (949) 850-9896 for a quote on sealing your existing driveway.
Not permanently, but often temporarily. The structural work at the garage level typically requires demolishing the apron in front of it. If your Unilock pavers were installed on a removable sand-set base as we recommend for soft-story buildings, they can be lifted, stored, and reinstalled after the inspection passes. If they were mortared to a concrete slab, you’re looking at more extensive replacement. We plan for this from the start on retrofit-prone properties.
