Unilock Construction in Mission District, CA

Unilock Construction in Mission District, CA | Milpitas Construction

We provide independent Unilock paver and retaining wall installation across Mission District, from driveway pulls to patio builds. The thing that separates our Unilock work here from anywhere else is what sits under the pavers: pre-1906 brick foundations, soft-story garages, and a sunny microclimate east of Twin Peaks that beats on south-facing hardscape year-round. We’re not authorized by Unilock, and we don’t pretend to be. We’re a full-scope general contractor led by Ken Stafford who specs materials by name and builds the base right the first time.

Why Mission District Residents Choose Us for Unilock Service

Milpitas Construction has been laying Unilock product in San Francisco long enough to know which paver models hold up on a Mission District lot and which ones fight you the whole way. We carry direct familiarity with Brussels Block, Brussels Dimensional, Beacon Hill, and Town Hall lines, and we know how each one behaves under Mission conditions: hot sun, flat-roof runoff, clay-heavy soil, and the brick foundations that quietly undermine a base if you ignore them. Ken Stafford grew up building in the Bay Area and learned early that you don’t lay a paver over whatever’s underneath and hope. That’s not how it works here. When we quote a Mission District driveway or patio, we’re quoting for what we’ll find when we pull the old surface, because we’ve found it before. We’re the same crew that manages roofing, windows, and interior remodels, so your hardscape doesn’t get orphaned from the rest of the property.

Common Unilock Construction Problems We Solve in Mission District

Mission District lots are old, narrow, and dense. That shows up in the hardscape in predictable ways. Here’s what we see:

• Settled or heaved pavers over original brick foundations. Pre-1906 Mission lots often have brick foundation remnants under what looks like a simple dirt base. When that brick shifts with each wet season, the Unilock course above it moves. We pull the settled course, rebuild the base over the brick with compacted aggregate, and re-lay the pavers in the original pattern.
• UV-faded and chalky surfaces on south- and west-facing patios. The Mission gets more sun than most of San Francisco because Twin Peaks blocks the fog. After a decade, a Brussels Block patio facing west can look chalky and worn. We replace the affected units with matching Unilock stone rather than trying to reseal UV damage that won’t come back.
• Efflorescence blooming on Brussels Block. That white powdery film shows up when water pools under the pavers instead of draining. It’s usually a base compaction problem, not a paver problem. We fix it by correcting drainage and re-compacting, then cleaning the surface. If the base wasn’t compacted to spec, no amount of surface sealer will keep the bloom from returning.
• Joint sand washout and edge restraint failure on narrow driveways. Mission District driveways are often graded into tight lots, and the flat roofs and parapets above them dump runoff directly onto the paving. That water pressure strips joint sand and pushes edge restraints out of place. We re-set edges, restore the restraint, and use a polymeric joint sand that stands up to Mission runoff.
• Mixed-use corner pull-ups with hidden soil surprises. The old mixed-use buildings along the corridors have had a century of utility lines, old fill, and buried brick shifting around under their driveways. We plan for surprises and don’t quote a surface job when the base is the real problem.

Unilock Service in Mission District: What Local Conditions Mean for Your Equipment

Here’s the fact that shapes every Unilock job in this neighborhood: the 1906 earthquake and fire spared the Mission’s building stock, so a paver driveway or patio pull here routinely lands over original brick foundations and pre-1906 redwood framing rather than the clean slab you’d find in a newer Bay Area suburb. That means the base has to be built around what’s actually underneath. On a Brussels Block driveway pull off a mixed-use corner near 24th Street, our crew found the base sitting on an original brick foundation with no proper sub-base, and one corner had settled where runoff from a flat roof pooled against the parapet. We pulled the settled course, rebuilt the base over the brick with compacted aggregate, re-laid the Brussels Block in the original running-bond pattern, and restored edge restraint so the water leaves the lot. That’s not a one-off. That’s the job in the Mission District. If a crew quotes you a paver job here without asking what’s under the surface, they haven’t done this work in this neighborhood.

Unilock Models & Products We Service in Mission District

We service the Unilock lines most common on Mission District properties: Brussels Block, Brussels Dimensional, Beacon Hill, and Town Hall. When it comes to replacement materials, we use Unilock’s own paving stones and edge restraints wherever they’re the right fit, and we switch to a quality aftermarket base aggregate and polymeric joint sand where OEM isn’t available or doesn’t suit a Mission base condition. We stock the common running-bond and herringbone pattern sizes for faster turnaround, so a partial re-lay on a Mission District driveway doesn’t stall waiting on material. If you need a full drive or patio replacement, we’ll walk the site, check what’s underneath, and quote the job with line items so you see exactly where the money goes.

FAQs – Unilock Construction in Mission District

Can Unilock pavers go over the original brick foundation on a pre-1906 Mission lot?

Yes, but not the way a standard base goes in. You need a compacted aggregate sub-base engineered to bridge the uneven brick and prevent differential settlement. We re-lay over original brick foundations regularly in the Mission District and rebuild the base to handle the load without tearing out the old brick unless it’s already failed. Call (877) 752-4194 and we’ll take a look at what you have.

Does the sunny Mission microclimate affect how my Unilock patio holds up?

It does. The Mission sits east of Twin Peaks and gets significantly more sun and less fog than the rest of San Francisco, which accelerates UV fading on south- and west-facing pavers and dries out joint sand faster. We account for that with material choices and proper drainage, and we’ll tell you if a patio that’s chalked out needs replacement units or just a re-sand and edge reset.

Will a paver driveway pull trigger SF Building Inspection Department review on a soft-story building?

If your Mission District building falls under the Soft-Story Retrofit Ordinance and the driveway work touches the garage or ground-floor structure, yes, it can trigger review. We handle the permitting side and coordinate with the Building Inspection Department so the paver work doesn’t stall your retrofit timeline. Call (877) 752-4194 if you’re not sure where your building stands.

Can you match the existing Unilock pattern on a partial Mission driveway re-lay?

Yes. If one or two courses have settled, we re-lay those courses in the original pattern rather than quoting a full replacement. We’ll pull the settled section, rebuild the base, and match the running bond or herringbone you already have so the repair disappears into the rest of the driveway.

What causes efflorescence on Unilock pavers, and is it a repair or replace?

Efflorescence is the white mineral bloom that appears when water moves through the paver and evaporates on the surface. It’s almost always a base and drainage issue, not a paver defect. We treat it by correcting the drainage, re-compacting the base, and cleaning the surface, if the paver itself is sound, you don’t replace it. Call (877) 752-4194 for a free inspection and we’ll tell you which it is.
