Concrete
Search for concrete work in Los Angeles and the first page is mostly national lead brokers. They have never seen a hillside cut-and-fill lot above Echo Park or a Torrance driveway that has been baking through sixty summers. They sell your phone number to whoever bought that ZIP code this month, and the crew that calls you back is a coin flip.
This page does something different, and it starts by telling you what it is. We run a concrete service in Greater Los Angeles. That means we cannot honestly hand you a ranked top five of our own competitors, and we are not going to invent one. So you get two things instead: our own pick, labelled as ours, and the actual checks a Los Angeles homeowner can run on any bid - including ours - before a single form goes in the ground. The second half is the part worth your time.
Concrete behaves according to what is under it, and what is under most of this basin is expansive clay. It swells when the winter rain arrives and shrinks back through the long dry summer, so the ground beneath a slab is in slow motion every single year. That yearly movement is what lifts driveway panels, opens joints into gaps you can catch a shoe on, and cracks flatwork that was poured on a thin, uncompacted base. The California Geological Survey is the public body that maps the region's geology and seismic hazards, and those maps are the reason a competent foundation detail in the Hollywood Hills looks nothing like one on the flats.
Then the local variations stack on top. Hillside lots in Silver Lake, Echo Park and the Hollywood Hills are frequently cut-and-fill, meaning half the pad is undisturbed ground and half is engineered fill - and a slab that bridges the two without the right steel will crack exactly along that seam. Near the coast in Santa Monica, Torrance and Long Beach the soil turns sandier and the marine air is corrosive, which punishes under-reinforced concrete where the steel sits too close to the surface. Everywhere in the basin, seismic code drives the reinforcement and the tie details on anything structural. And everywhere in the basin, the sun pulls water out of fresh concrete faster than a contractor from a wetter state expects.
That last point is the one homeowners never hear about and it matters enormously. Concrete does not dry, it cures - a chemical reaction that needs water to keep running for days. Concrete that is allowed to dry out in the LA sun instead of being kept damp ends up with a weak, dusty, easily-scaled surface, no matter how good the mix was on the truck.
Almost none of the cost difference between bids is in the concrete itself. It is in the work you cannot see once the pour is finished:
This is the single highest-value ten minutes in the whole process, it is free, and most people skip it. The Contractors State License Board publishes a public lookup: Check a Contractor License or Home Improvement Salesperson (HIS) Registration. You can search by licence number, by business name, or by the contractor's own name, and CSLB states that the search verifies information including complaint disclosure.
A licence number on a truck door, a flyer or a business card is not evidence of anything until you have typed it into that system and seen its current status yourself. Do it for every bidder, and do it before price enters the conversation - once you are attached to a number, you will find reasons to skip the check.
Not every concrete job is permitted, and the honest answer depends entirely on what you are building. Structural work - foundations, structural slabs, retaining walls - is permitted and inspected inside the City of Los Angeles through the Department of Building and Safety. A new or widened driveway apron is a different animal again, because it lands in the public right-of-way rather than on your lot. Outside the city proper, Pasadena, Glendale, Burbank, Santa Monica, Torrance and Long Beach each run their own building departments with their own counters and their own timelines.
You do not need to become an expert in this. You need one question answered in writing: which permits does my scope require, and who is pulling them? A contractor who answers "none" before asking what you want built has not looked at your job. A contractor who wants you to pull an owner-builder permit for structural work is asking you to carry the liability for their pour.
You do not need to understand every answer in technical depth. You are listening for whether the answers are specific to your lot. A contractor who has walked the site and read the ground gives different answers than one quoting a catalog average.
Disclosure first, because it is the whole context for what follows: the service below is part of Trusted Local Network. We have a direct commercial interest in it. That is exactly why it is the only one listed - we are not going to referee a field we are competing in.
LA Concrete Contractors Co is the crew we point Los Angeles homeowners to for driveways, patios, foundations, stamped and decorative work, sidewalks, retaining walls, slabs, resurfacing and repair. Their published bar is the one this page has been describing: base and steel sized for the basin's expansive clay, hillside cut-and-fill and seismic code rather than a national one-size spec; a firm written bid before forming, with change orders only when the scope changes; and a tear-out-and-re-pour workmanship warranty. They cover the City of Los Angeles plus Pasadena, Santa Monica, Long Beach, Glendale, Burbank and Torrance, and they handle the permitting on work that needs it.
Three of their own guides answer the questions we get asked most, and they are worth reading before you take any bid - ours included: what a driveway pour actually costs in LA, when a concrete permit is required here, and why LA concrete cracks in the first place.
Outside Greater Los Angeles, this page is not useful to you and we are not going to pretend it is. We do not have a concrete recommendation for the Inland Empire, Orange County, Ventura, San Diego or the Central Valley, and rather than pad this page with companies whose work we have no basis to speak about, we have left the gap visible. If you are outside our coverage, the licence lookup and the question list above still work perfectly well on whoever you find locally - honestly, they are the more valuable half of this page anyway.
No, and it is deliberately not one. We run a concrete service across Greater Los Angeles, which means every other concrete contractor in this metro is a direct competitor of ours. A ranked top five written by a company that put itself on it is not a ranking, it is an advertisement. So this page lists one recommendation, says openly that it is ours, and spends the rest of its length on checks you can run yourself - on us or on anybody else.
Use the Contractors State License Board's own lookup, Check a Contractor License or Home Improvement Salesperson (HIS) Registration. You can search by licence number, by business name, or by the contractor's personal name, and CSLB states the search will verify information including complaint disclosure. Do this before you discuss price. A licence number printed on a truck or a flyer means nothing until you have seen its current status on the state's own system.
It depends on what is being poured. Flatwork replaced in kind on private property is treated differently than structural work. Foundations, structural slabs and retaining walls inside the City of Los Angeles are permitted and inspected through the Department of Building and Safety, and a new or widened driveway apron sits in the public right-of-way rather than on your lot, which is its own approval. Ask any bidder which permits your specific scope needs and who is pulling them. A contractor who says none are needed without asking what you want built has not looked.
Two reasons stack here. Much of the basin sits on expansive clay soils that swell with winter rain and shrink through the long dry summer, so the ground under a slab moves every year. On top of that, the sun pulls water out of fresh concrete fast, and concrete that dries rather than cures is weaker at the surface. Neither is avoidable, which is why base preparation, reinforcement, control joints on a real grid, and a proper cure are the whole job here rather than optional extras.
No. Nobody pays for placement anywhere on Trusted Local Network. The single service recommended below is part of our own network, we have a commercial interest in it, and we have said so in the body of the page as well as here. The other links on this page go to the state licensing board, the city building department, the California Geological Survey and the American Concrete Institute - none of which have any relationship with us.
