Unilock Construction in Mission District, CA | Daly City Construction
Unilock construction in the Mission District means pavers, retaining walls, and driveway systems installed the way this neighborhood actually requires: engineered bases over buried creek silt, drainage daylighted at the sidewalk, and details sized for tight Victorian side yards. Daly City Construction is an independent contractor working with Unilock product lines across zip code 94110, not a manufacturer dealer, so our specs come from excavation findings, not a catalog. If you’re pricing a paver patio, driveway, or retaining wall in the Mission District, call (866) 505-5254 for a free estimate. Tell me what the house needs, not what you think it needs, then we’ll figure out the right fix.
Why Mission District Residents Choose Us for Unilock Service
We’re the crew that pulls up failed patios and shows the homeowner why it failed. On Mission District lots, the answer is usually underground. Noel Cabrera, our owner, grew up in Daly City’s Westlake district and trained in construction technology at City College of San Francisco before years of residential work across San Mateo and San Francisco counties. He’s spent enough time swinging a hammer to know the difference between a paver problem and a base problem, and on the old Mission Creek marshland, that distinction matters more than anywhere else in the city.
Our Unilock sales & service work stays product-accurate: we use Unilock OEM units, caps, and their matching polymeric sand for every repair and rebuild, and we source compatible geogrid and drainage aggregate from quality suppliers. Color stays consistent. Dimensions stay consistent. Warranty-eligible components stay consistent. When we recommend a full rebuild instead of a patch, it’s because the excavation showed base failure that a localized repair would just repeat. That’s the kind of call you can only make from experience, and it’s why Mission District homeowners call us instead of a crew that’s never dug through 19th-century silt.

Common Unilock Construction Problems We Solve in Mission District
- Brussels Block and Beacon Hill pavers settling into bowls. Prior contractors laid these directly on compacted native soil over the former Mission Creek channel. No geotextile, no engineered aggregate base, no drainage. Within two or three wet seasons the patio rocks and dips. We tear it out, rebuild the base to stable ground, and relay with OEM polymeric sand.
- Unilock retaining wall blocks with face spalling and joint creep. On sloped or narrow Mission District lots, fog-driven damp meets unvented crawlspace air and attacks walls built without drainage gravel or geogrid behind them. Blocks shift, caps loosen, faces chip. We rebuild with proper drainage and reinforcement, not just cosmetic re-stacking.
- Pisa2 driveway aprons cracking and heaving. Tree roots and undocumented 19th-century footings sit just below grade on many Mission District drive entries. If the base was cut too thin, the crossing cracks under vehicle load. We excavate deep enough to deal with what’s actually down there, then compact properly.
- Rivercrest caps with efflorescence blooms and chip-out. Shaded north-facing side yards and overhangs in the Mission’s warm, damp microclimate trap moisture. When polymeric sand is underfilled, water sits in the joints and the caps stain and flake. We pull the caps, clean the joint lines, and refill to full depth.
- Driveway sealing on aging Unilock surfaces. Mission District sun is real, even in a foggy city. UV and moisture degrade joint sand over time. We seal and re-sand before the surface starts shifting, extending the life of a sound base.
Unilock Service in Mission District: What Local Conditions Mean for Your Pavement
Mission District blocks sit on the filled channel of former Mission Creek. That’s not a historical footnote. It’s what our crews encounter every time we excavate for a paver installation here. We routinely cut into buried tidal silt, old timber pilings, and undocumented 19th-century foundations that force us to redesign base depth and drainage mid-project. Flat, fill-free neighboring districts simply don’t share this condition. You can lay a Unilock patio on six inches of compacted aggregate in Noe Valley and it’ll hold for decades. Try the same spec on a lot crossing the old creek channel, and you’ll get a patio that sinks into a bowl within three years. That’s not a paver problem. That’s a ground problem, and it’s the single most important factor in how we spec Unilock work in the Mission District. We don’t guess at it. We excavate, read the soil, and build the base to match what’s there. On a Liberty Street Victorian side yard, our crew pulled up a Brussels Block patio that had settled into a bowl where the old creek channel crosses under the lot, with silt visible in the excavation. We removed the failed native-soil base down to stable ground, installed geotextile, compacted aggregate, and a drainage channel to daylight at the sidewalk, then relaid the pavers with OEM polymeric sand. The patio has stayed true through two wet seasons.
Unilock Models & Products We Service in Mission District
We install and service the full Unilock lineup you’re likely to see on Mission District properties: Brussels Block and Beacon Hill for patios and walkways, Pisa2 for driveways and crossings, and Rivercrest Wall for retaining walls and raised planters. On repair work, we use Unilock OEM units, caps, and their matching polymeric sand so color and dimension line up with the existing installation. We also source compatible geogrid and drainage aggregate that meet Unilock’s installation specifications. We repair when the base is sound and the issue is localized: a cracked paver, a loose cap, a joint that’s blown out. We recommend full rebuild when settlement traces back to base failure rather than surface wear. The difference shows up in the excavation.

AfterUnilock Service Pricing in Mission District

What drives the number in the Mission District specifically? Base depth and drainage. If we’re building over the old creek channel, we’re excavating deeper, hauling more spoil, and installing geotextile and drainage that a flat-lot job doesn’t need. That’s not a markup. That’s the difference between a patio that lasts and one that doesn’t. Every estimate includes the excavation findings, the base spec, and the Unilock product line itemized. Call (866) 505-5254 and we’ll walk the site with you.

FAQs – Unilock Construction in Mission District
Because your lot likely sits over the filled channel of former Mission Creek, where buried tidal silt and old timber pilings sit just below the surface. Your neighbor’s lot with Unilock repair in Noe Valley is on stable native soil. A paver patio is only as good as its base. If the base was built on uncompacted creek silt without geotextile or drainage, it’ll settle no matter which Unilock paver is on top. We find this on Mission District jobs constantly. The fix is a full rebuild to stable ground with proper base and drainage. Call (866) 505-5254 for an excavation-based assessment.
Sometimes, but on Mission District lots we usually say no. If the concrete is sound and level, an overlay can work with the right setting bed and edge restraint. But if the concrete has already cracked from underlying soil movement over the old creek channel, laying pavers over it just hides the problem until the pavers mirror the same cracks. We’ll check the slab first. If it’s compromised, remove it and build a proper base. Free estimate: (866) 505-5254.
Generally, replacing a driveway surface with pavers on the same footprint doesn’t require a building permit, but the Mission District’s Department of Building Inspection does require permits when you’re changing the driveway width, altering the curb cut, or disturbing right-of-way at the sidewalk. We coordinate with SFDBI on Mission District driveway replacements and flag any permit requirements before work starts. Call (866) 505-5254 and we’ll check your specific address.
If the wall is structurally sound and the staining is efflorescence from water wicking through underfilled joints, we can fix it: pull the caps, clean the joint lines, refill with OEM polymeric sand, and reset everything. If we also find joint creep or blocks shifting out of plane, that points to missing drainage gravel or geogrid behind the wall, and a surface fix won’t hold. On Mission District lots with fog-driven damp and unvented crawlspace air, underbuilt walls fail slowly but steadily. We’ll dig a test hole behind the wall and show you what’s there before recommending repair or rebuild. Call (866) 505-5254.
A paver patio typically runs $3,500 to $11,000, and a paver driveway $7,000 to $18,000, depending on size, access, product line, and how much base work the old creek channel conditions require. Driveway replacement runs $5,000 to $14,000. You’ll get a line-item estimate that separates materials, excavation, base, drainage, and installation. Call (866) 505-5254 for an exact quote.
