Homes and storefronts across San Leandro
San Leandro is a short drive up the freeway from our base in Union City. Much of the city is established neighborhoods of older single-family houses, with shops and small businesses along the main streets and flatter blocks out toward the bay shoreline. We see a lot of the same kinds of houses next door in San Lorenzo and up the hill in Castro Valley.
On these older lots, the concrete we replace has usually had decades to settle, crack and get pushed around by roots, and the ground under it was rarely prepared the way we'd do it today. That's why a job here usually starts with digging out the old base, not pouring over it.
What to know about permits and pricing in San Leandro
Building permits here are issued by the city's Building Official through the San Leandro Permit Center, which is where residents file applications and ask about current codes, so whether your slab, wall or footing needs one is the city's call, not ours. When a job does need one, the city's review becomes part of the schedule, and we handle the application and inspections and keep you informed. Two checks are worth making on anyone you hire, because the city issues building permits only to a California-licensed contractor or the property owner, and anyone doing business inside city limits needs a San Leandro business license before starting. We're licensed and fully insured. The same city page lets you check whether your address is inside San Leandro at all, which is worth doing near the edges, since city rules apply only within them.
What moves the price is mostly what you can't see on day one: how much old concrete comes out, how much digging and packing the ground needs, the size of the area, the finish you pick and how close a truck can get on a narrow street or tight side yard. Some slabs also need rebar, the steel inside that holds the concrete together if it cracks. The schedule turns on permit review when there is one, on the weather and on curing, the wait while fresh concrete gains strength before it can take feet or tires. My written estimate lists what's included and what isn't, so you see your own number and where it comes from. We do the same work in Hayward and back home in Union City.
Services in San Leandro, CA
Concrete driveway building
Older driveways here often crack and sink because they were poured on raked dirt. We dig out, pack a proper base and pour new.
Garage floor concrete
Many older San Leandro garages have floors cracked from decades of cars. Our garage floor concrete work replaces the worn slab over a packed base.
Concrete patio construction
A patio on a tight backyard lot has to send rain away from the house. We set the slope before the pour and check where the water goes.
Concrete sidewalk building
Front walks on older blocks get lifted by roots until they trip people. We break out the bad sections and pour new walk that sits flush.
Concrete retaining walls
Sloped yards here need a wall that holds the soil and drains water behind it. We plan the footing and drainage before building, so the wall holds.
Concrete footings
Additions, porches and steps on older houses here need footings that meet current code. We dig to the depth the plans call for and pour before framing starts.
What San Leandro's older houses ask of concrete
The city runs a course for owners of older raised-floor homes that weren't built to modern seismic standards, teaching simple steps to strengthen them, and plenty of neighborhoods here are full of those houses. When one of them needs new footings or foundation work, I look closely at what's already there before quoting, because the old concrete under a raised floor is often thinner or patchier than you'd guess. Then we pour the new work to the plans the permit approves.
Out in the yard, the trouble usually starts underneath. Many old slabs here sit on dirt that was only raked level, so they sink, crack and sometimes tip water back toward the house. We dig out and pack the subgrade, the ground the slab sits on, slope it so water runs away from your house, and plan control joints, shallow cuts that give the concrete a straight line to crack along instead of a random one.

How a San Leandro job goes
Call or send the form
Call (510) 319-6825 or send the form, and we'll set a time for me to come out and hear what you have in mind. It helps if you're home for that visit, so you can show me where water sits and what bothers you about the old concrete.
Go over the site together
I look at the ground, the drainage and how a truck will reach the site, then write an estimate that spells out what's included and what isn't. We talk through the choices before you decide anything, so you know exactly what you'd be paying for.
Handle permits, prep and pour
If the job needs a permit, we take care of the application and inspections with the city and keep you posted along the way. Our crew of finishers and laborers then digs out, packs the base, pours and finishes, with me checking in on site.
Walk the finished job together
When the work is done, I walk it with you and explain how long to keep feet and cars off while it cures. I also go over how to care for the surface so it stays in good shape.
Concrete questions from San Leandro homeowners
How much does a new concrete driveway cost in San Leandro?
The cost depends on your driveway's size, how much old concrete has to come out and how much base work the ground needs, so the honest answer is a written estimate after I've seen it. A plain broom finish, the light brushed texture that gives tires and shoes grip, costs less than stamped or colored concrete. If the budget is tight, I'd keep the base work and simplify the finish, because the base is what keeps a slab from sinking and it can't be added later.
How do I find out if my concrete patio or driveway needs a permit in San Leandro?
Ask the city, and we do that for you before we price the job, because the city requires a permit to build or alter a building or structure and its examples don't settle every slab. Separately, the city's Do I Need a Permit page says moving 50 cubic yards or more of soil, about six dump truck loads, or digging a hole or trench 5 feet deep or more calls for a grading permit. A big tear-out or a regraded yard is where we check that first.
How do I replace the end of my driveway where it meets the street in San Leandro?
If the work touches the street, you need an encroachment permit from the city's Public Works engineering office, because any work on a street or roadway in San Leandro requires one. We sort out at the estimate where your property ends and the street begins, then line up that permit before the crew breaks out the old apron, the sloped piece that meets the curb.
Do I need a permit for a shed slab in San Leandro?
The city's permit FAQ lists one-story detached sheds and playhouses with no more than 120 square feet of floor as needing no building permit, but that speaks to the shed itself, so we confirm the slab with the Permit Center before we pour. Either way, a shed slab still needs a packed base and a little slope so rain runs off instead of pooling under the door.
Does a concrete retaining wall need a permit in San Leandro?
A short one may not, because the same city FAQ lists retaining walls no more than 4 feet from the bottom of the footing to the top of the wall as needing no building permit, as long as there's no surcharge, extra weight like a slope or driveway above it pushing on the wall, and no stored liquids of the kinds the code lists held behind it. Taller walls, or ones carrying that extra load, fall outside the exemption. That FAQ isn't dated and the city's codes were recently updated, so we confirm before we build.
Which building codes apply in San Leandro right now?
San Leandro's current codes took effect on January 1, 2026, built on the state's building code with local changes the city added. The structural rules were modified for earthquake design, which matters for footings, foundations and walls, so we build to the plans the permit approves. You can read the city's summary on its building codes page, and the Permit Center answers code questions about a specific project.
