San Leandro: older homes, tired concrete
San Leandro is right next door to us in Castro Valley, and the work here looks a lot like what we see in San Lorenzo to the south. Most calls come from established neighborhoods of older single-family homes. Many of them are raised-floor houses with a driveway, a front walk and a set of steps that have been there nearly as long as the house. There are shops and businesses along the main roads too, but here we mostly hear from homeowners and small property owners whose concrete has done its time.
Older houses shape the job. The original slabs were often poured on a thin base, and new work has to meet foundations and steps that have shifted over the years, so I check the grade and where the water runs before I write anything down.

Concrete work we do in San Leandro
Concrete driveway building
Many San Leandro driveways are the original pour, cracked and sinking where the base settled. We tear out, dig down to firm ground, pack new base and pour.
Concrete patio construction
Older backyards here often have a patio that tips toward the house and holds water after rain. We set the new slab to fall away from the walls.
Stamped concrete services
Stamped concrete gives a patio or front walk a stone or brick look that suits older San Leandro houses. We build its base like any plain slab.
Concrete sidewalk building
Front walks on older lots lift where roots or settling push panels out of line. We replace the broken panels on a packed base so they sit level.
Concrete steps construction
Raised-floor houses here mean front steps, and old steps chip and pull away from the porch. We form new ones with rebar, steel bars that hold them together.
Foundation installation
Additions and garages on older lots need foundations that match the plans and pass inspection. We dig, set the steel and pour to the approved plans.
What we know from working in San Leandro
In San Leandro, the city's Building Official issues building permits, and applications go through the city's Permit Center, where you can also ask about the current building codes. The city only issues building permits to a California-licensed contractor or the property owner, and anyone doing business inside the city needs a San Leandro business license before starting, so it's fair to ask any contractor about both. We're licensed and insured. I check with the city early, and when a job needs a permit we handle the application and set up the inspections, because a permit job can't start until the permit is issued and that sets the first date on the schedule. If you're not sure your address is inside the city limits, the city's building page lets you check, since city rules only apply inside the city.
Most of what we pour here is replacement work on older lots, and access is usually the first thing I look at. A narrow driveway beside the house or a backyard with a tight gate changes how we get concrete in, and lining up the truck, the pump and the crew is what I did for years before I learned the trade from the finishers I scheduled. What you pay mostly follows the tear-out, the base work, the size and finish of the slab and that access, and the estimate I write after walking the job says what's included. The schedule turns on the permit, if there is one, and on curing, the time new concrete needs to harden before it carries weight. We work the same way over in Oakland and across the cities around it.

San Leandro concrete questions
How much does it cost to replace a concrete driveway in San Leandro?
The cost comes down to how much old concrete has to come out, how much base work the ground needs, and the size, thickness and finish of the new slab. On older lots, tight access can mean pumping the concrete instead of pouring straight from the truck, and a stamped or colored finish costs more than a broom finish, the light texture that keeps tires and shoes from slipping. If the budget's tight, cut the finish and not the base, because nobody can fix a base once the slab is sitting on it.
How do I know if a retaining wall needs a permit in San Leandro?
The city's permit FAQ says a retaining wall 4 feet tall or less, measured from the bottom of the footing to the top of the wall, doesn't need a building permit, as long as nothing like a driveway or a slope is loading the soil behind it. A bigger dig can also need a grading permit, which the city ties to moving 50 cubic yards of soil or more, about six dump truck loads, or a hole or trench 5 feet deep or more. We confirm with the Permit Center before we dig either way.
Do I need a city permit for concrete work at the street in San Leandro?
Yes, any work on any street or roadway in San Leandro needs an encroachment permit from the city's Public Works Department. That can come up where a new driveway has to meet the street, so I look at where yours ends during the estimate, and when the job needs that permit we handle the application.
Which building codes apply to foundation work in San Leandro now?
San Leandro builds to the current California Building Standards Code with the city's own amendments, and those codes took effect at the start of 2026. The state and the city added requirements for local conditions, including changes to the structural rules for earthquake design, which matters most for foundations, footings and anything that carries the house. If you own an older raised-floor home, the city also describes a course for homeowners on simple steps to strengthen it against earthquakes.
What causes concrete driveways to crack and sink in San Leandro?
Most cracking and sinking starts under the slab, with a base that was raked flat instead of dug out and packed, so it settles along with the dirt. Water running toward the house or under the edges makes it worse, and so do joints cut late or skipped. We pack the subgrade, the ground the slab sits on, check where the water will run, and cut control joints, shallow grooves that give the slab a straight place to crack as it shrinks.
How long does it take before I can drive on a new driveway in San Leandro?
You can walk on a new driveway well before you can drive on it, and the driving wait is the one to plan around, because car weight on half-cured concrete is how a new slab gets cracked. We also time the pour to stay out of the hottest part of the day, so the top doesn't dry weak and dusty. I'll lay out the order of work and the dates at the estimate, so you know when to park on the street.
