Unilock Construction in Mission District, CA | Timberline Contractors
We’re an independent contractor providing Unilock paver installation, repair, and replacement across Mission District, CA. The one thing that makes our Unilock work here different is that we’ve spent years adapting their paver systems to lot-line Victorian and Edwardian lots where drainage has nowhere to go but under a neighbor’s foundation. If you’re planning a patio, driveway, or walkway with Unilock pavers in the 94110, call (866) 253-5808 for a free estimate.
Why Mission District Residents Choose Us for Unilock Service
Most Mission District blocks are packed tight. Houses from the 1880s to 1920s sit shoulder to shoulder, and your paver patio is often six inches from somebody else’s foundation. That’s not a job for a contractor who learned hardscaping on suburban cul-de-sacs. We’ve installed Unilock Brussels Block, Beacon Hill, Town Hall, and Richcliff across dozens of Mission District rear yards, front walks, and driveway aprons, and we know how their base, edge restraint, and jointing details behave in this soil and climate. Nelson Fung, our owner and general contractor, grew up in Chinatown watching his grandfather debate tile prices at hardware stalls on Broadway. That early obsession with materials turned into formal training at Los Angeles Trade-Technical College, and today he runs Timberline Contractors with the same eye for substrate details that separates a patio that lasts from one that settles in three years. We’re a Unilock sales & service contractor who specifies genuine Unilock pavers, edge restraint, and polymeric sand for color and dimensional consistency, and we’ll tell you plainly where a quality aftermarket aggregate makes more sense than paying for brand markup.

Common Unilock Construction Problems We Solve in Mission District
- Efflorescence on Brussels Block and Beacon Hill pavers. Mission District backyards are sheltered from the fog that blankets the rest of San Francisco. Irrigation overspray hits the paver surface and never fully evaporates in those tight, shaded yards. Repeated wetting and drying cycles pull minerals to the surface as white streaking. If the efflorescence has penetrated more than a few millimeters across the field, we recommend replacement rather than repeated sealing that won’t hold.
- Edge restraint failure where pavers meet original wood-frame foundations. Many Mission District homes have soft mortar joints at the foundation line that crumble under lateral load. When a Unilock edge restraint is pinned against that crumbling mortar, the whole paver field can creep outward within two seasons. We install restraint into sound concrete or compacted base, never into old mortar.
- Settlement and rutting in driveway aprons off the street. Mission District lots sit on sandy fill and historic rubble from the neighborhood’s original construction. If a Town Hall driveway apron is laid over a base that wasn’t excavated deep enough, the first rainy season shows exactly where the shortcut was. We excavate to depth, geotextile, and compact in lifts.
- Polymeric joint sand washout on sloped entry walks. Soft-story garages at street level mean entry walks slope toward the street. Runoff from the Mission’s paved surfaces concentrates on those slopes and erodes joint sand before it can lock up. We compact and activate the joint sand properly and, where needed, adjust the slope to slow the water.
- Base failure under lot-line patios. When a paver patio abuts a neighbor’s wall with zero drainage setback, water that pools against the base will undermine it. We direct water to the street or a dry well, not under the adjacent foundation. This is the most common failure we correct from previous installs.
Unilock Service in Mission District: What Local Conditions Mean for Your Equipment
Because most Mission District lots are built lot-line to lot-line with shared party walls, a Unilock paver patio or driveway often abuts a neighbor’s wall with zero drainage setback. Meaning: any water that runs off your pavers is running straight at somebody else’s foundation. We build base and edge details that direct water to the street or a dry well without sending it under the adjacent foundation. On a rear-yard patio off Treat Avenue, we pulled up an old Brussels Block field that had settled at the house wall because the original base was only two inches of sand over rubble. We re-excavated to eight inches, installed a geotextile separator, compacted Class II base in lifts, and re-laid the Brussels Block with Unilock edge restraint pinned into the existing concrete curb, tying the new patio into the soft-story garage apron without disturbing the neighbor’s shared wall. That’s the difference between a patio that lasts in the Mission and one that firms up for the photo and settles by spring. Do it right the first time or explain yourself twice.
Unilock Models & Products We Service in Mission District
We work with the full Unilock hardscape catalog, with the most frequent Mission District installs and repairs involving Brussels Block, Beacon Hill, Town Hall, and Richcliff. We specify genuine Unilock pavers and their matching edge restraint and polymeric sand for color and dimensional consistency. When the original base aggregate or geotextile spec is unavailable, we substitute a quality aftermarket product that meets or exceeds the load rating. For Mission District turnaround, we keep the most common edge restraint profiles and polymeric sand on hand, and we can pull Unilock pavers from local suppliers quickly. If a paver is cracked or the base has failed, we repair that panel. If efflorescence has taken over the field, we don’t seal over it, we replace it.

FAQs – Unilock Construction in Mission District
Yes, in some cases they can, but we won’t do it blindly. If the existing slab is structurally sound with no active cracking or drainage failure, we can lay Unilock pavers over it with a setting bed and proper edge restraint. If that slab is cracked or pitched toward your foundation or a neighbor’s wall, we’ll recommend removal and a proper base. Call (866) 253-5808 and we’ll tell you what your slab can handle before you spend a dollar.
We never pin edge restraint into old mortar or crumbling foundation material. Where your lot line is flush against a neighbor’s wall, we install edge restraint into sound concrete curb or compacted base on our side of the line, with a drainage gap or channel that directs water away from their foundation. On Mission District lot-line lots, this detail is the difference between a five-year patio and a twenty-five-year one.
That white streaking is mineral deposits pulled to the surface by repeated wetting and drying. Mission District yards are sheltered from summer fog, so irrigation overspray sits on the paver surface longer and evaporates slower. If the efflorescence is surface-level, we can clean and reseal. If it has penetrated deep into the paver, sealing becomes a recurring expense and we recommend replacement. Call (866) 253-5808 and we’ll assess whether your field is cleanable or done.
For a rear-yard patio or walkway that doesn’t alter the street-facing facade, usually not. For a driveway apron that touches the public right-of-way or changes the curb cut, yes, it likely requires a permit from SF Public Works and possibly Department of Building Inspection review, whether you’re in the Mission or seeking Unilock in San Francisco more broadly. In the Calle 24 and Mission historic districts, any exterior work facing the street can trigger additional review, even pavers. We’ll tell you what applies to your specific lot before we cut anything.
We excavate to a minimum of eight inches for pedestrian applications and deeper for driveway aprons, removing Mission District rubble fill until we hit stable soil. Then we lay a geotextile separator, compact Class II base in lifts, and set the pavers on a screeded bedding layer. That depth is non-negotiable on lot-line lots where a settling patio will pull water toward a soft-story garage foundation. Call (866) 253-5808 for a base-depth assessment at your property.
