Unilock Construction in Mission District, CA | San Bernardino Contractors
We install and repair Unilock segmental paver systems across Mission District, from Brussels Block driveways to U-Cara retaining walls. For homeowners exploring our Home Remodeling in Mission District, paver hardscape is often the first outdoor upgrade. What makes our work here different is simple: we build Unilock hardscape around the soft-story retrofit reality every Mission District garage faces. If you’re planning a paver driveway, patio, or walkway in the 94110, call (855) 473-5620 for a free estimate.
Why Mission District Residents Choose Us for Unilock Service
Most crews in San Francisco know concrete. Fewer actually understand how a Unilock system behaves when it’s laid over ground that’s been dug up, retrofitted, and re-compacted in patches. Our lead, Ruben Castillo, grew up watching his uncle reroof houses and frame garages on a shoestring budget in San Bernardino’s Westside. That early training taught him to read the ground before laying anything on top of it. When we set Unilock pavers in the Mission, we’re looking at what’s underneath first: old brick footings, new grade beams, century-old fill, drainage paths. As your Mission District General Contractor, we coordinate with retrofit crews so nothing gets laid twice. We’re an independent crew, not tied to Unilock corporate. That means we recommend what works on your lot, not what moves inventory.

Common Unilock Construction Problems We Solve in Mission District
- Joint-sand pumping and unit rocking on rear-addition patios. Mission rear additions often keep their original flat-roof flashings, and when winter rain gets under those under-detailed edges, it sheets straight onto the paver perimeter. We rebuild the edge, repair the drainage pitch, and re-set the field so the pavers stop swimming.
- Border and soldier-course migration on driveways. Many Mission garages sit on the original 1906-era brick footing, never stripped and compacted before pavers went down. The border course walks outward within a season or two. We cut back to stable subgrade and build the base properly.
- Heaving and lippage where hardscape meets a soft-story retrofit grade beam. New concrete on one edge, unreinforced fill on the other. Pavers bridge the seam and move differently on each side. We re-set those sections with uniform compacted aggregate so the transition stops telegraphing through.
- Efflorescence and moss staining on shaded north-facing walks. Even in the Mission’s sunny microclimate, Victorian overhangs keep side-yard pavers damp. Efflorescence works up through the joints, moss finds the organic matter. We clean, repair the base drainage, and re-sand with the right joint material.
- Whole-field settlement from inadequate base prep. The classic Mission problem, especially after a retrofit. A driveway that gets re-laid without addressing the mixed subgrade under it will settle again inside two winters. We rebuild the base once and the pavers stay put.
Unilock Service in Mission District: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on a generic Unilock page. The Mission District’s 1906-era Victorians and Edwardians were built with unreinforced soft-story ground floors, and when the mandated seismic retrofit goes in, the original brick footings under those garage-level floors get exposed and replaced with new concrete grade beams. That means the paver driveway or patio tied to your garage is now being re-laid across a perimeter that is brand-new concrete on one edge and century-old fill on the other. If your contractor treats that seam as a normal base transition, the pavers will heave within a season or two. We saw this on Liberty Street when an Edwardian’s soft-story retrofit left the driveway apron looking like a wave pool. The owner’s Unilock sales & service question wasn’t which paver to buy. It was why his year-old Brussels Block field had already moved. The answer was under the pavers.
Unilock Models & Products We Service in Mission District
We work with the Unilock platform directly: Brussels Block in both standard and Fullnose profiles for driveways and step caps, Brussels Dimensional for clean-edged walkways, Onyx for contemporary flat surfaces, U-Cara for retaining walls that actually hold the Mission’s sloping lots, and Town Hall and Beacon Hill where permeable-compatible profiles make sense on tight drainage-challenged yards. When we repair a field, we source genuine Unilock units and matching edge restraint so color and profile continue to line up with the rest of your hardscape. Aftermarket pavers that are “close enough” in color never match after a Mission summer sun hits them. If the base section is sound, we re-set and re-sand the affected area. Once the subgrade is moving, we rebuild rather than chase settlement one unit at a time. As Ruben puts it, “If it’s not built right the first time, you’re just paying for it twice.”

AfterUnilock Service Pricing in Mission District
Here’s what Unilock construction typically runs in the Mission District. These are real market ranges for paver work on our local lots, and they account for the base rebuilds and drainage corrections this neighborhood often needs.
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
| Driveway Sealing | $250 – $700 |
What drives the final number is base condition. A patio over stable ground is straightforward. A driveway apron over mixed retrofit subgrade takes more aggregate, more compaction, more edge restraint. That’s not a markup. That’s what it costs to build it once.

FAQs – Unilock Construction in Mission District
Yes, you should wait. If the retrofit crew is still working on the grade beam or the ground floor framing, the subgrade around the garage is in flux. Laying pavers now means they’ll be torn up or undermined before the project is finished. Let the retrofit complete, then let us inspect the transition zone before we build. Call (855) 473-5620 and we’ll schedule a look.
In most cases, no, because the rear of a Mission lot is not the street-facing facade. Historic review in this district is triggered by visible street-side changes, not backyard hardscape. If your rear patio is on a corner lot or extends to a side street, there can be edge cases. We’ll flag it before you commit.
Because the subgrade under them is likely the original uncompacted fill from 1906, and the winter rains are getting under the edge and destabilizing it. The side yard of a Liberty Street Victorian often sits on fill that was never engineered for load. We strip the affected section, find the drainage problem, and rebuild the base before resetting the pavers. Call (855) 473-5620 for an exact assessment.
They can, if the soil below them percolates. Some Mission lots have dense clay under the topsoil, and permeable pavers won’t fix a drainage problem if the water has nowhere to go. We test the subgrade first. Town Hall and Beacon Hill profiles are permeable-compatible, and we’ll tell you honestly whether they’re right for your yard or whether a different drainage fix comes first.
Usually, we repair the affected section. Genuine Unilock pavers are designed to be individually replaceable, and matching units are available. We only recommend whole-field replacement when the base itself has failed and is moving underneath the pavers. Estimate is free: (855) 473-5620.
