Unilock Construction in Mission District, CA | Ashford Contractors
We provide independent Unilock construction service across Mission District, CA for paver driveways, patios, and replacement work, and we’re also your Mission District General Contractor for related projects. What makes our Unilock work different here is simple: we know this neighborhood’s historic Victorians, soft-brick foundations, and Planning Department review process, and we build paver systems that hold up to all three. Call (877) 752-3868 for a free estimate.
Ashford Contractors has installed Unilock pavers on narrow lots from Valencia to Guerrero, and we understand how these pre-1906 wood-frame rowhouses demand more than a stock paver job. Glen Mossier, our owner, grew up watching Bay Area homes get rebuilt after water damage and learned early that the base under the paver matters as much as the paver itself. Our Unilock sales & service work across Mission District reflects that: we plan for drainage, settlement, and the review process before the first paver goes down.
Why Mission District Residents Choose Us for Unilock Service
Most Mission District lots are tight, and many sit on unreinforced soft-brick foundations that shift more than homeowners expect. We’ve worked around those conditions long enough to know where paver systems fail here and how to prevent it. Our approach to Unilock in Mission District starts with the base: we re-level where original brick foundations have settled, compact properly, and use Unilock’s proprietary polymeric sands so joints stay locked through the damp winters.
We’re independent Unilock specialists, not manufacturer-affiliated. That means our recommendations are based on what actually works in Mission District, not what a brand rep wants sold. We source Unilock OEM components and compatible aftermarket base materials where they make sense. For Mission District homeowners with historic facades, we also handle the paperwork side: we know when a paver driveway replacement on a Valencia or Guerrero Street Victorian may need Planning Department sign-off, and we design around it where possible.

Common Unilock Construction Problems We Solve in Mission District
- Efflorescence on Brussels Block pavers. Mission District’s damp winters leave surface moisture on concrete pavers, and when polymeric sand isn’t compacted correctly, white mineral deposits bloom across the surface. We remove it and re-sand with a proper moisture-stable joint compound.
- Joint sand erosion and paver shifting on sloped driveways. Winter rains run hard down Mission slopes, and when the original soft-brick foundation settles underneath, pavers start to drift. We re-level the base and add edge restraint before re-sanding, so the system stays put.
- Color fading from intense Mission sun. The Mission District is fog-free and gets more direct sun than most of San Francisco. Standard Unilock concrete pavers fade over years of that exposure. We advise on sealed finishes and paver lines with better UV resistance when replacement makes sense.
- Edge restraint failure at Victorian facades. On narrow lots, pavers meet historic facades inches from the property line. Poor base prep here causes lippage and spreading. We install proper edge restraints and compact in tight quarters without disturbing the adjacent structure.
- Settling over original brick foundations. Many Mission homes still sit on pre-1906 soft-brick footings that settle unevenly. A paver patio or driveway laid without addressing that shows dips within two winters. We re-grade, add structural base layers, and only then lay the Unilock product.
Unilock Service in Mission District: What Local Conditions Mean for Your Equipment
Here’s something specific to Mission District that doesn’t apply in Unilock repair in Noe Valley or Bernal Heights: any project touching a facade within a historic district can trigger Planning Department review. A paver driveway replacement that’s visible from the street may need design approval if it alters the front setback’s character. We’ve handled exactly this. On a Valencia Street Victorian, we replaced a crumbling concrete driveway with Unilock Brussels Block pavers in a herringbone pattern to match the home’s historic character. The original soft-brick foundation had settled, so we re-leveled the base and added a hidden drainage channel to handle winter runoff. The homeowner was thrilled that the new driveway passed planning review without triggering a full historic review because we matched the original setback and used permeable joint sand. That’s not a detail a contractor learns on their first Mission District job; it’s knowledge built from working this neighborhood’s rules.
Unilock Models & Products We Service in Mission District
We install and service the full Unilock product range most relevant to Mission District homes: Brussels Block for driveways and patios where a historic look matters, Beacon Hill for a more formal flagstone appearance, Town Hall for larger paved areas, and Pisa for walkways and small patio spaces. For repairs, we use Unilock OEM components and proprietary polymeric sands to maintain system integrity. For older installations, we’ll assess honestly: localized repair with compatible aftermarket base materials often makes more sense than full replacement when the base is sound. We stock common Unilock paver types and sands locally for faster turnaround on Mission District jobs.

FAQs – Unilock Construction in Mission District
It depends on whether your property falls within a historic district and whether the driveway is visible from the street. In many Mission District cases, a paver driveway replacement that matches the original setback and uses permeable materials can proceed without full historic review, but Planning Department sign-off may still be required for facade-adjacent work. We handle this assessment for you. Call (877) 752-3868 and we’ll tell you what applies to your address.
Mission District gets more direct sun than nearly any other San Francisco neighborhood, so standard Unilock concrete pavers fade noticeably faster here than they would with Unilock in Visitacion Valley or the foggy Sunset. We recommend sealed finishes and UV-resistant paver lines for Mission District installs. Call (877) 752-3868 to talk about which paver holds its color best on your lot.
Not directly. The original soft-brick foundations under many Mission District homes settle unevenly, and installing pavers over that without a proper structural base leads to dips and shifting within a couple of winters. We excavate, re-level, and build a compacted base first. That’s the only way Unilock pavers stay flat on these older lots. Call (877) 752-3868 for a free assessment of your base conditions.
For patios behind the front setback, Chinatown Unilock service-style historic review rarely applies regardless of paver choice. When visibility is a factor, Brussels Block in a herringbone pattern closely matches the look of older Mission District hardscape and reads as period-appropriate to reviewers. We’ve used that exact approach successfully. Call (877) 752-3868 to talk through your specific Guerrero Street situation.
On narrow Mission District lots where homes share party walls, water has nowhere to go except into the neighbor’s foundation. We install hidden drainage channels and grade the paver surface away from structures, often using permeable joint sand so water infiltrates rather than pooling. This is standard on our Mission District jobs. Call (877) 752-3868 to have us look at your lot’s drainage pattern.
