Unilock Construction in San Francisco, CA | Elmstead Remodeling San Francisco
We provide independent Unilock construction and repair across San Francisco, from paver patios in the Sunset to driveway replacements in Noe Valley, as your trusted General Contractor in San Francisco. What makes our Unilock work here different is straightforward: we plan every paver, walkway, and retaining wall around the city’s mandatory soft-story retrofit requirements, which most contractors do not think about until a building inspector brings it up. If you need Unilock work that will not have to be torn out and redone when your seismic retrofit comes due, call us at (831) 480-4497 for a free estimate.
Why San Francisco Residents Choose Us for Unilock Service
We have spent years laying Unilock pavers and building Unilock retaining walls on San Francisco hillsides, in fog-shaded backyards, and over soft-story garages where the ground does not behave the way it does in a flat suburban lot. Graham Stein, our owner, learned the trade at Los Angeles Trade-Technical College and has managed construction crews across California for nearly three decades. His team has completed kitchen and bathroom renovations in homes from the Sunset District to within walking distance of Dolores Park, but our Unilock hardscape work is where that structural experience matters most. We buy Unilock sales & service products through Bay Area distributors, so color blends and unit dimensions match what is already on the ground. When we re-lay a driveway or replace a cracked paver, we are matching the original layout, not guessing at it.
Every job starts with a written price before any work begins. We bring drop cloths and shoe covers on every visit. We set quiet hours so a family is not chased out of their own home while pavers are being cut. And we are independently owned, not manufacturer-affiliated, which means our advice about when to repair versus replace is not tied to moving product.

Common Unilock Construction Problems We Solve in San Francisco
- Efflorescence on fog-shaded pavers. Marina and Sunset District yards that sit in persistent fog see white mineral deposits wick up through Unilock concrete pavers. We remove the buildup and reapply a breathable sealer suited to damp microclimates, rather than sealing moisture in and making the problem worse.
- Settlement at curb cuts over soft-story garages. San Francisco’s pre-1940 housing stock often sits above ground-floor garages with substrate that was never compacted to modern seismic code. We see Unilock paver driveways settle and create trip hazards at the curb line. We remove, recompact, and reset pavers with steel edge restraint.
- Salt-air pitting within three blocks of Ocean Beach. The outer Richmond and Sunset districts get marine air that corrodes concrete pavers. We replace spalled units one-for-one, matching the original color, instead of pushing a full resurfacing quote.
- Root heave from mature street trees. In Noe Valley and Glen Park, shallow utility trenches and big canopy trees push Unilock walkways out of plane. We lift the affected run, repair the base, and reset the same pavers where they are still sound.
- Paver creep next to shear-wall retrofits. When a soft-story retrofit is already in place, poorly edged pavers shift against the new steel work. We install steel or aluminum edge restraint so the hardscape does not interfere with the structural system.
Unilock Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s mandatory Soft Story Program imposes a constraint that no other major U.S. city applies to nearly the same degree: any new hardscape adjacent to a soft-story building must not obstruct the eventual installation of steel moment frames or shear walls. For a Unilock patio or walkway, that means designers have to think in terms of removable sections and engineered clearances. If the pavers are laid tight to the foundation line with no plan for pulling a section back out, the retrofit contractor may have to cut through the hardscape, and the homeowner pays for that twice. We lay Unilock paver patios and driveways with clean edges and designated removable runs where a future moment frame is likely to land. On a Marina District mid-block project, our tech re-laid a 400-square-foot Unilock Brussels Block driveway that had settled over a soft-story garage and created a three-inch trip hazard at the curb cut. We removed the pavers, recompacted the base with recycled concrete to 95% density, and set a steel restraint edge exactly where the future moment frame would go. The driveway was level, code-compliant, and did not interfere with the owner’s scheduled seismic retrofit. That is the kind of sequencing that matters when you live in a city that retrofits by mandate.
Unilock Models & Products We Service in San Francisco
We work regularly with Unilock Eco-Promenade, Town Hall, Brussels Block, and Lineo Dimensional Stone. Eco-Promenade’s permeable joint design works well on San Francisco lots where stormwater runoff is a planning-department concern, though we adjust the base profile for the city’s clay-heavy hillsides. Town Hall and Lineo Dimensional Stone are common on walkways and retaining walls in denser neighborhoods. For jointing we use spec-grade polymeric sand and jointing compounds that meet or exceed Unilock’s installation guidelines. We keep commonly matched color blends sourced through local distributors so a partial repair in the Marina does not sit for three weeks waiting on a pallet from the Midwest.

FAQs – Unilock Construction in San Francisco
Yes, when the installation is designed with removable sections and clearances that do not obstruct future steel moment frames or shear walls. We set edges so the retrofit contractor can access the foundation line without cutting through your paver work. Call (831) 480-4497 if you want us to look at your specific lot.
They hold up structurally, but the persistent moisture and shade lead to efflorescence and, within a few blocks of the beach, salt-air pitting. The right sealant and a properly drained base make the difference. We spec both for the specific block you live on.
Salt air accelerates surface spalling and pitting on concrete pavers within roughly three blocks of the ocean. The fix is targeted unit replacement with matched color blends, not a full re-surface, which keeps the cost to about half what a new install would run.
Yes. We source through Bay Area distributors that carry the long-running Unilock lines, and we test-match both color and texture. Where a discontinued blend is not available, we will tell you that before you pay for anything, and we will show you the closest current alternative in person.
They can be, but only with proper drainage and a reinforced base. Hillside lots add lateral earth pressure that a flat yard never sees. We size the wall, the drain, and the setback for the slope you actually have, and the written quote reflects that engineering. San Francisco service area work like this is exactly what we price and build.
