What San Leandro concrete jobs usually involve

The calls we get from San Leandro sound like the ones from across the East Bay: a driveway that's cracked and dropped, front steps that have started to tip, a patio that's seen better days, and now and then a foundation question. Property owners call too about bigger flatwork, the flat pours like parking areas and long walks. It's the same work we do next door in Oakland and farther north in Kensington.

Older houses usually come with older concrete, so a job here often starts with breaking out a slab that's done its time and finding out what it was sitting on. That answer shapes the rest of the job.

Concrete services we offer in San Leandro

We bring every service we offer to San Leandro, from a single set of front steps to a parking lot for a property owner. I start each job by looking at the ground, the slope and where water goes now, and by asking how you'll use the slab, because those answers decide the base, the thickness and where the joints go. Each service below has its own page with more on how we do it.

  • Concrete driveway building

    Cracked, sunken driveways usually have a problem under the slab, not in it. We take out the old one, rebuild the subgrade, the ground the slab sits on, and pour thick enough for cars.

  • Concrete patio construction

    Patios get the most use of any slab in the yard, so size and placement matter more than people expect. We plan both with you, then cut control joints so cracks follow straight lines.

  • Stamped concrete services

    Stamped concrete suits a patio or walk that should match an older home's brick or stone. We press the pattern while the top is still soft and seal it so the color holds up.

  • Concrete sidewalk building

    Front walks take foot traffic every day, so a cracked or tipped section is a tripping problem. We pour new sections on a packed base with a broom finish, a scratched texture for grip when wet.

  • Garage floor concrete

    Older garage floors are often thin, cracked and soaked with oil. We break out the old floor, pack the base and pour a new slab with rebar, steel that keeps cracks from opening wide.

  • Decorative concrete

    Some owners want a patio or entry with color or exposed stone instead of plain gray. We talk through the look first, because a decorative finish can't be changed once the concrete sets.

  • Concrete retaining walls

    Sloped yards need a wall to hold the dirt, and a leaning old one usually has no drain behind it. We build on footings with drainage so water doesn't push the wall over.

  • Concrete floor installation

    Workshops, additions and converted garages need an inside floor flat enough for what goes on it. We set the height carefully and finish it smooth for tile, flooring or plain use.

  • Concrete pool decks

    A pool deck takes splashing water and bare feet, so a slick or cracked one is a hazard. We slope it to shed water and give it a textured finish for grip.

    Explore service

  • Concrete steps construction

    Front steps on older houses often pull away from the porch or settle unevenly. We set new steps on solid footings and make each rise the same height, so they're easier to climb.

    Explore service

  • Slab foundation building

    Additions, garages and backyard cottages often sit on a slab foundation poured right on the ground. We dig out, compact the base and place the steel the plans call for before the truck arrives.

    Explore service

  • Foundation installation

    Older houses sometimes need a new foundation where the original has cracked or crumbled. We form and pour footings and walls to the engineer's plans, with me running the job.

  • Concrete parking lot building

    Small commercial and apartment lots wear out where delivery trucks turn and water sits. We build them thicker where the heavy traffic goes and slope them so rain drains off instead of pooling.

    Explore service

  • Concrete footings

    Decks, fences, posts and small additions all rest on footings, the buried concrete that spreads the load into firm ground. We dig until we hit firm soil and check the hole before we pour.

    Explore service

  • Foundation raising

    When one corner of a house has settled, doors stick and cracks run up the walls. We find out why it dropped, then raise and support that section.

    Explore service

  • Concrete cutting

    Adding a drain, a doorway or a utility line often means cutting through a slab that's already there. We saw clean lines so only the section that has to go comes out.

Working in San Leandro: permits, prices and planning

Before we pour anything in San Leandro, a few things get settled. Here's who issues the permit, what you can check about any contractor, and what moves your price and your dates.

Permits and licenses for concrete work here

In San Leandro, the permit is the city's call. The City of San Leandro's Building Official issues it for building, altering, repairing or demolishing a structure, and applications and code questions go through the city's Permit Center. When a permit applies, the city's review and its inspections set the pace, so I can't give you a pour date until we know what the city needs.

Two things are worth checking on any contractor you hire here. The city only issues building permits to a California-licensed contractor or the property owner, and it requires anyone doing business inside city limits to hold a city business license before starting. We're licensed and fully insured, and you're welcome to ask us about both before you sign.

  • I look up which office covers your address before I price the job.
  • When a permit applies, we handle the application and set inspections with you.
  • Code questions about your address can go straight to the Permit Center.

What moves the price and the schedule

The price of a concrete job here mostly turns on what we find under the old slab and how much has to come out. Breaking out and hauling old concrete, digging out soft ground, the size and thickness of the new slab, the steel inside it and a stamped or colored finish all add to it.

If the budget's tight, cut the fancy finish before the base, because the base is what keeps a slab from sinking and nobody sees it after the first day. The schedule turns on the permit, the weather and curing, the wait while new concrete hardens before you can walk or drive on it. Your own figure comes in the written estimate after I've seen the site.

  • Midday heat can leave a weak, dusty top, so we pour earlier.
  • Rain on pour day pushes the pour back to protect the fresh surface.
  • Stamped or colored finishes take extra steps, so they add time.

What we find on San Leandro houses and lots

Every lot is different, but older East Bay houses tend to show the same handful of problems. These are the ones I look for first when I walk a San Leandro property.

  • Older raised-floor homes

    The city offers homeowners a course on strengthening older raised-floor homes that weren't built to modern earthquake standards. For us that matters at the steps, footings and any slab that meets the house, so I look at how the house is supported before I plan anything that ties into it.

  • Old slabs on unpacked dirt

    Across the East Bay, a lot of the old driveways and patios we break out sat on dirt that was raked level and never packed, so the slab sank with the ground under it. That's why we dig below the soft layer and pack the base before any concrete goes in.

  • Slabs that tip toward the house

    Old slabs that settled often tip back toward the house, so rain runs to the foundation instead of the yard. Before we set forms, I walk the lot to see where water already goes, then set the new slab to carry it away from your walls.

  • Tight side yards and back lots

    Plenty of lots have a narrow side yard and a backyard the truck can't reach. When that's the case, we plan how the concrete gets back there, by pump or by wheelbarrow, and you'll see that extra labor in the estimate before anything is booked.

  • Mature trees near the slab

    Big trees near a driveway or walk lift and crack slabs as their roots grow. I look at where the roots run before we plan, and sometimes the right answer is moving the slab edge or adding steel there rather than pouring the same shape again.

How we plan and run a concrete job

Concrete jobs go right or wrong on decisions made before the pour. Here's how we make those decisions with you, and who you'll be dealing with from the first visit to the cleanup.

We talk the job through before we pour

Concrete is hard to undo, so I'd rather spend more time talking it over at your driveway than have you guess. I'll sketch where the joints go, show you which way the water will run and explain what the slab sits on. You should know what you're paying for before the truck shows up.

I'll also tell you plainly what concrete can't do. No slab is crack free, because concrete shrinks as it dries and the ground moves. What we control is where the cracks go and how far they open, with a packed base, steel where it belongs and joints cut on time. A hairline crack along a joint is the slab doing what we planned.

  • The owner gives every estimate

    I come out myself to look at every job and give the estimate, so the person who prices your job is the one who'll run it. Our crew does the forming, pouring and finishing with me running the job, so the plan doesn't change hands between the estimate and the pour.

  • Estimates in writing, easy to compare

    We put every estimate in writing, so you can line it up against other bids. If another number is lower, the written breakdown helps you see whether the difference is in the base, the thickness or the finish.

  • Running our own crew since 2017

    I spent years at a desk before I went to work on an East Bay concrete crew and learned the trade from the ground up. I started this business in Berkeley in 2017, and the lesson that stuck is that the base and the drainage decide how a slab ages.

  • Tell us about your project

    We stand behind the work with one promise, "Your satisfaction, guaranteed." To start, call (510) 345-1330 or send the form with a few lines about your driveway, patio or steps, and we'll set up a time for me to come out and look.

San Leandro concrete questions, answered plainly

These are questions we hear from San Leandro homeowners about permits, codes and cost. If yours isn't here, ask me when I'm out at your property and I'll walk you through it.

How much does a new concrete driveway cost in San Leandro?

Your price comes mostly from work you can't see, breaking out the old slab and rebuilding the base, so I give it in a written estimate after I've looked at the driveway. A plain broom finish on a simple shape costs the least, and any permit the city requires for your address adds to both the cost and the schedule.

How do I know if my driveway replacement needs a permit in San Leandro?

Ask the city's Permit Center, because the city's permit guidance doesn't spell out driveway work either way, and we sort that out for your address before we price it. Any part of the work in the street needs a separate permit from the city's Public Works Department, and a job that moves 50 cubic yards of soil or more, about six dump truck loads, needs a grading permit.

Do I need a permit for a concrete retaining wall in San Leandro?

Not for a small one, according to the city's permit FAQ, which lists retaining walls no more than 4 feet tall, measured from the bottom of the footing to the top of the wall, among work that needs no building permit. That only holds when there's no extra load on the wall, like a driveway or slope above it, and no stored liquids behind it. The FAQ isn't dated, so I confirm the current rule with the city before we price a wall.

Does a backyard shed on a concrete slab need a permit in San Leandro?

The city's FAQ lists a one-story detached shed or playhouse of 120 square feet or less as not needing a building permit. That rule is about the shed, so when you want a slab under it, I check with the Permit Center whether the slab or the digging needs its own approval before I price it.

Which building codes apply to concrete work in San Leandro right now?

The city's current building codes took effect on January 1, 2026, built on the state's building code with local changes. Those changes add requirements for local conditions, including structural rules for earthquake design, so footings, foundations and walls get built to them.

How do I check if my address is inside San Leandro city limits?

Use the address check on the city's building and safety page, since San Leandro's permit and business license rules apply only to work inside the city. If you'd rather skip it, give me your address when you call and I'll look it up.
