Unilock Construction in Mission District, CA | Toolbox Contractors
We install and repair Unilock paver and wall systems across the Mission District, including Brussels Block, Beacon Hill, Richcliff, and Tribeca Cobble lines. What makes our work here different is simple: we build for zero-setback lots, shared party walls, and San Francisco Planning’s neighborhood notification rules, so hardscape gets settled before the first paver goes down. Call (855) 382-3257 for a free estimate on paver patios, driveways, or full additions in the Mission.
Toolbox Contractors is an independent Unilock service provider. We are not authorized or endorsed by Unilock, and we quote repairs honestly rather than defaulting to a full tear-out.
Why Mission District Residents Choose Us for Unilock Service
Norm Castellano runs Toolbox Contractors from the angle of a builder who’s had to untangle plenty of previous contractors’ messes before real work could start. That matters on Mission District General Contractor jobs, where a sunken patio behind an 1890s Edwardian flat usually means someone skipped base compaction the first time. We know these lots. We know how old redwood-framed rear additions settle differently than new concrete, and we build our paver bases with that in mind.
We stock genuine Unilock pavers and matching edge restraint for Mission District jobs, but we’re not brand-loyal to a fault. Where a run is being extended, we use OEM Unilock units. Where performance matters more than brand match, we use quality aftermarket polymeric joint sand and base aggregate. That’s the honest split, and it’s what keeps a small repair from becoming a five-figure replacement.
Local crews matter here more than most neighborhoods. Mission District blocks are dense. Access to a rear yard is often a 30-inch side yard corridor. We plan our staging, our base material delivery, and our paver drops around that reality, and we do it without blocking a neighbor’s only path to the street.

Common Unilock Construction Problems We Solve in Mission District
- Efflorescence and salt bloom on Brussels Block and Richcliff. Mission District wet-season moisture wicks up through the base course against zero-setback walls, pushing soluble salts to the paver surface. It looks like a white haze and it usually appears after the first heavy rains. We clean it, then fix the drainage that caused it.
- Settling and lipping where paver patios meet old redwood-framed rear additions. Uncompacted subgrade on backfilled Mission lots creates a lip at the transition. You feel it underfoot. We excavate the bad base, re-compact in lifts, and reset the pavers so the transition is flush.
- Moss and algae in shaded, fog-trapped side yards. Some Mission side yards never dry between storms. Fog settles in, the sun never reaches the pavers, and moss takes hold. We recommend larger-joint profiles or surface treatments that handle constant damp.
- Joint sand washout in narrow walkways where downspouts discharge directly onto pavers. A downspout dumping onto a paver walkway will strip the polymeric sand in one season. We redirect downspouts to proper drainage, then re-sand. Without the redirect, you’ll re-sand every year.
- Edge restraint loosening along shared walkways. On Mission lots with a shared neighbor walk, the edge restraint takes constant lateral pressure. When it fails, the outside courses drift. We reset the restraint with proper spikes and a compacted base edge.
Unilock Service in Mission District: What Local Conditions Mean for Your Equipment
Here’s what a generic Unilock page won’t tell you: on a dense Mission District block, a rear addition, a new paver patio, or even a driveway apron is visible from neighboring yards and the street. That visibility can trigger San Francisco Planning’s neighborhood notification process. A “small renovation” turns into a public design review. We’ve seen it happen on blocks near 24th Street, where a planned paver driveway became a topic for the whole street.
So before the first paver goes down on a Mission District job, we settle the hardscape layout. We check the rear yard line, the side access, the drainage path, and whether the work falls under the Planning Department’s notification rules. That’s not bureaucracy for its own sake. It’s the difference between a project that goes in clean and one that stalls for months because a neighbor filed an objection. We’ve built enough Unilock patios in the Mission to know when a design is going to draw attention and when it won’t, through our Home Remodeling in Mission District experience.
Unilock Models & Products We Service in Mission District
We service the Unilock lines most common on Mission District properties: Brussels Block, Beacon Hill, Richcliff, and Tribeca Cobble. Brussels Block and Richcliff show up on rear patios and front walkways. Beacon Hill works for driveways and tighter applications. Tribeca Cobble is the choice for older homes where a cobbled look matches the 1900s streetscape.
On OEM versus aftermarket parts, our approach is practical. Extending an existing run? We match with genuine Unilock pavers. Re-sanding joints or rebuilding a base? We use quality aftermarket polymeric sand and aggregate, chosen for the Mission District’s wet winters and drainage needs. For residents who need quick turnaround on a repair, we keep common Unilock profiles available locally. You can also read more about our broader Unilock sales & service capabilities.

AfterUnilock Service Pricing in Mission District
Here’s what Unilock construction work runs in the Mission District, based on current local project scopes:
| Service | Typical Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Home Addition | $45,000 – $130,000 |
The biggest cost drivers in the Mission District are access and drainage. A rear patio on a lot with only side-yard access costs more in labor and material handling than one with street-level rear access. A paver driveway on a lot where the ground slopes toward the house needs a more involved base and drainage plan. Free estimates include a walkthrough, a written scope, and a fixed price. Call (855) 382-3257 for an exact quote.

FAQs – Unilock Construction in Mission District
Yes. We’ve done it on plenty of Mission District lots where the side yard is barely 30 inches wide. It means hand-carrying base material and pavers through the corridor rather than running a machine, which adds labor cost, but it’s standard for this neighborhood. Call (855) 382-3257 and we’ll give you a straight answer on your specific lot.
It can, especially on dense blocks where neighbors can see the work from their yards or the street. San Francisco Planning’s neighborhood notification rules apply to certain exterior changes, and Mission District lots with zero setback are more likely to draw notice. We confirm this before we start, so there are no mid-project surprises.
Efflorescence happens when wet-season moisture wicks up through the base course against zero-setback walls, carrying soluble salts to the paver surface. It’s cosmetic, not structural, but it’s a sign the drainage needs attention. We clean the pavers and address the moisture path so it doesn’t return every winter.
Usually, yes. If a few units are cracked or settled but the base is sound, we reset and relay rather than push a full replacement. We’ll tell you honestly whether the base needs rebuilding or just localized repair. Call (855) 382-3257 for a free assessment.
For a side yard that never fully dries between fog and rain, we lean toward Unilock pavers with a tighter joint profile and surface treatment that resists moss and algae. Brussels Block works well, but joint width and drainage matter more than the paver itself. We’ll spec it based on your specific yard.
