Unilock Construction in Mission District, CA | Workshop Contractors
We provide independent Unilock service across the Mission District, from small paver patios behind Edwardian flats to driveway replacements over buried creek fill. The thing that separates our Unilock work here from what you’d get in Noe Valley or Potrero Hill is simple: we excavate and detail drainage for the Mission’s seasonally moving, moisture-holding filled bayland soils before a single paver goes down. Noel Figueroa and our crew handle the whole scope, so the base, the units, the edge restraint, and the drainage are one contractor’s responsibility. Call (844) 384-3361 to schedule a free estimate.
Why Mission District Residents Choose Us for Unilock Service
We work on Unilock sales & service assemblies every week in the Mission District, and that repetition means we know the brand’s dimensional tolerances and base-prep requirements well enough to call out a bad installation before it becomes a winter drainage problem. Our background is general contracting, not just hardscaping, so when a paver patio meets a soft-story foundation or a roof deck ties into a Victorian’s parapet, we see the whole intersection instead of just the paver layer. Noel grew up around tradesmen who handed him his first framing hammer, and he still approaches every Unilock project the way a carpenter would: square lines, honest base work, and trim that actually meets the corner. That means we’re not the crew that slaps pavers on thin gravel and disappears before the first rain.

Common Unilock Construction Problems We Solve in Mission District
- Efflorescence and persistent damp staining on Brussels Block pavers. Mission District soil moisture wicks up through an underbuilt base, especially on graded flats where water has nowhere to go. We correct the drainage plane and re-sand with Unilock joint sand so the white bloom stops returning every winter.
- Joint sand washout and paver settlement over clay-heavy, wet soil. Much of the Mission sits on filled bayland that holds water. Bases spec’d for aesthetics instead of winter rain load fail fast. We re-excavate and compact a proper aggregate base that carries the load, then relaid the units on top.
- Edge restraint failure on patio borders against 1880 – 1906 wood-frame foundations. The house moves one way, the hardscape moves another, and the perimeter joints open up. We install Unilock edge restraint with a clean separation detail so differential movement doesn’t tear the border apart.
- Clogged permeable joints from deferred cleaning. Freeze-thaw isn’t the risk here. Damp Mission District yards grow weeds and silt that clog a permeable paver system designed to drain. We clean and re-sand the joints so the water actually moves through the way Unilock intended.
- Heaved patios over buried creek fill. A surprising number of Mission District patios sit over the old Mission Creek alignment. The fill holds moisture and moves seasonally. Without proper excavation and compaction, pavers heave. We fix the base, not just the surface.
Unilock Service in Mission District: What Local Conditions Mean for Your Equipment
Here’s the thing most paver contractors don’t tell you about the Mission District: a large part of the neighborhood sits over the buried Mission Creek culvert and filled bayland, so soils under a paver patio stay wet and move seasonally in a way a Noe Valley or Potrero Hill hillside lot generally doesn’t have to account for. That changes how deep we excavate and how we detail drainage before a single Unilock unit goes down. Permit reviewers at SF DBI flag Mission addresses fast too. Much of the neighborhood is in a Historic Resource survey where anything pre-1945 needs a preservation review, and a chunk sits over that buried creek, so contractors see foundation and drainage surprises the rest of the city doesn’t. On a flat off Valencia near the old Mission Creek alignment, our crew tore out a heaved patio of mismatched pavers behind a pre-1906 Edwardian and found the original base was thin gravel over wet clay fill. We re-excavated, set a proper compacted aggregate base with drainage away from the wood foundation, and relaid Brussels Block with Unilock edge restraint and fresh joint sand. The patio now sheds winter rain instead of pooling against the building.
Unilock Models & Products We Service in Mission District
We service the Unilock lines built for dense urban lots and moderate coastal climates: Brussels Block, Brussels Dimensional, Beacon Hill, and Town Hall. When repairs call for matching units, we source from current production runs, not mismatched remnant pallets, so color and dimension stay consistent. We specify Unilock’s own edge restraint and joint sand on every job, because generic substitutes undercut the very tolerances the brand is engineered around. Whether it’s a new paver driveway on a Mission District flat or a repair on a Victorian-era patio, the parts come from the same manufacturer the original design called for, and the labor comes from us.

FAQs – Unilock Construction in Mission District
Because much of the Mission District sits over buried Mission Creek fill or clay-heavy bayland, the subgrade holds moisture and expands seasonally, so a base that was compacted dry in summer can move once winter rains arrive. The fix is deeper excavation, proper aggregate compaction, and drainage detailed to shed water away from the paver bed, not just cosmetic re-leveling. For our Home Remodeling in Mission District projects, we always start with the base. Call (844) 384-3361 and we’ll tell you if your base is the problem or the symptoms.
Often, yes. The Mission District has one of the city’s densest concentrations of pre-1906 wood-frame housing, and SF DBI’s Historic Resource survey flags most pre-1945 addresses for preservation review. A patio that changes drainage or grading at the rear of a protected building can trigger review. We coordinate that paperwork, because it’s part of the job, not a surprise.
Yes, but the structural question comes first. Many Mission District buildings have unreinforced soft-story ground floors, and a paver driveway adds load and changes drainage against that vulnerable level. We evaluate the foundation condition and the drainage plane before we spec the paver system. A driveway over a compromised soft story needs more than pavers; it needs the base and the building working together.
For tight backyards behind Edwardian flats, Brussels Block and Brussels Dimensional give a dense urban look with manageable joint spacing. Town Hall works where you want a clean architectural line, and Beacon Hill suits moderately loaded driveways. Roof decks are a different animal, they need weight checks and waterproofing coordination, and we’ll tell you if pavers are even the right call for your structure.
Clean the joints before they clog, not after. Damp Mission District yards grow moss and silt faster than dry hillside lots, and once the permeable joints clog, water pools on top instead of draining through. We recommend an annual joint cleaning and re-sanding with Unilock joint sand, and a drainage check before the first winter rain. Need Chinatown Unilock service? We cover that too.
