Services in Richmond, CA

Concrete driveway building

Older Richmond driveways often sank where the base was never packed. We dig out, pack a firm base and pour a new one sloped toward the street.

Concrete retaining walls

Hillside lots here often need soil held back for a flat yard. We build concrete retaining walls with drainage behind them so water can't push them over.

Concrete steps construction

Older front steps on sloped lots crack and settle over the years. We tear them out and pour new ones with even risers and a gritty finish.

Concrete sidewalk building

Tree roots and age lift the walks along older Richmond streets, leaving edges to trip on. We cut out the lifted panels and pour new ones flush.

Concrete patio construction

Flat backyards near the bay can hold water against the house after a rain. We pour patios that fall gently away from your walls.

Garage floor concrete

Older detached garages here often have cracked, sunken floors that collect oil and water. We break out the old slab and pour a new one over packed base.

Richmond, CA properties and local conditions

A lot of the driveways and walks we look at in Richmond are as old as the houses, with cracks, a sunken panel by the garage and a puddle that sits after it rains. Most of the time the base was just raked level instead of dug out and packed, so the slab settled right along with the dirt under it. We dig down to a firm subgrade, which is the ground the slab sits on, pack the base in layers and set the slope so water runs away from the house. That base is invisible on pour day and it's the first thing folks want to trim from a budget, but if something has to give, I'd rather you pick a plain finish over a good base than a fancy one over a bad base. On the farm we'd say you can't fix a leaning fence post by painting it.

Up in the hills, the questions are about steps, walls and where the water coming down the slope ends up. On the flat lots toward the bay, water has less reason to leave on its own, so we check which way it runs before we set a single form.

Permits, paperwork and getting a truck in around Richmond

Richmond's Building Division issues the building permits here, and when your job needs one, nothing gets poured until it's issued. The city asks contractors to show a state contractor's license card, a workers' comp insurance certificate and a current Richmond business license when they register for a permit, so those are fair things to ask anyone you're thinking of hiring. We're licensed and fully insured, we can pull the permit as your contractor and handle the paperwork and inspection calls for our part, and we check your job with the city before we start instead of guessing. The price moves with how much old concrete comes out, how much base work the ground needs and the finish you pick, and the schedule mostly turns on the permit and the weather. Your written estimate spells out what's included, like whether hauling the old concrete away is part of it.

We're based in Orinda and come over the hills to Richmond the same way we head out to jobs in Oakland or back toward Moraga. The ready-mix trucks come in off I-80 or the Richmond Parkway, and on the tighter streets in the older neighborhoods I plan ahead where the truck can park and whether a backyard patio needs a pump or a line of wheelbarrows, because getting concrete to the forms is part of what you pay for.

What happens after you call us about a Richmond job

  1. Call and set a walk-through

    You call (925) 257-6590 or send the form, and I set a time to come out to Richmond myself. It helps if you're home so we can talk through what you want while we're standing on it.

  2. Walk the job together

    I look at the ground, where the water runs and anything in the way, and ask what the concrete has to carry or hold back. You get a written estimate that lists what's included, so you know what you're paying for before anything starts.

  3. Line up permits and marking

    Once you're ready, we line up any permit and get the utilities marked before we dig. The city says most single-trade permits and residential remodels with no drawings are issued once it receives and checks the application documents, while bigger jobs take longer.

  4. Prep, pour and walk it

    Our crew lead and finishers dig out and pack the base, set the forms, pour and finish, and I'm usually there on pour day. Before we pack up, I walk the finished work with you.

Frequently asked questions

Do I need a permit to replace a concrete driveway in Richmond, CA?

Plan on checking, because the city says a permit is likely required for any project that isn't on its list of work exempt from permits. That list also notes that exempt items can still need separate plumbing, electrical or mechanical permits. We check your job with the city before any concrete comes out.

Who can pull a building permit in Richmond?

The city issues permits only to property owners or their authorized agents and to licensed contractors. Contractors also show the license, insurance and business license papers mentioned above when they register. Applications go in online, or in person by appointment if you can't submit electronically.

Do I need a permit for a fence on top of a retaining wall in Richmond?

Yes for the fence, since the city requires a Planning Division permit for any fence, even though fences no taller than 7 feet are on its list of work exempt from a building permit. The wall under it is its own question, so we check that with the city before we pour the footing.

How much does a new concrete driveway cost in Richmond?

Most of a driveway's price comes from tearing out and hauling the old one, the base work under the new one, its size and thickness, and the finish. A plain broom finish, the light texture that gives tires and shoes some grip, costs less than stamped or colored concrete, and adding rebar, the steel that holds the slab together if it cracks, adds some. A steep approach or a tight spot for the truck adds forming and labor, and your written estimate shows each of these so you can compare bids line by line.

How long does it take before I can drive on a new concrete driveway?

You'll be walking on it well before you can park on it, because concrete keeps gaining strength for days while it cures, which means we keep it damp and leave it alone to harden. I give you the walking day and the driving day for your mix and that week's weather, and we sort out where you'll park in the meantime, which matters on a Richmond street with tight parking.

What causes new concrete to crack, and will mine crack in Richmond?

Most concrete cracks a little as it dries and shrinks, so the goal is to choose where it cracks and keep those cracks tight. We cut control joints, the straight grooves that give the slab a place to crack neatly, early enough that they work, and we pack the base so the slab doesn't settle. We also pour early in the day, because a slab finished in the midday heat can end up with a weak, dusty top.

About Richmond, CA

Richmond runs from the hills down to a long stretch of bayfront, and most folks here know the waterfront, the Bay Trail along the national historical park and the Rosie the Riveter Memorial at Marina Park. That memorial's walkway is the length of a ship's keel and slopes toward the bay, and I like it, because a walk built to fall toward the water is how we think about every slab. Our Richmond calls feel a lot like the ones we get over in Berkeley, with older houses, older concrete and homeowners who want it done right this time.

Plenty of the houses here have been added onto and patched over the years, so the old concrete can hide a buried footing, an old pipe or a second layer poured on top of the first. We plan for that, and some of it we only learn once the old slab is out and we can see what we're building on.
