What's involved in cutting concrete at your house?

Concrete cutting in Walnut Creek means sawing, coring or breaking out part of a slab or wall to make an opening, a trench or a hole for a pipe without cracking the concrete you're keeping. The sawing is usually the quick part. The planning before it decides how clean the cut comes out.

Usually the reason isn't the concrete itself. It's a drain line that has to cross under the patio, a sunken stretch of driveway you want gone, or an opening in a garage or foundation wall. The price moves with what we're cutting, slab or wall, how thick it is, how much rebar it has, which is the steel that holds a slab together, and how far the saw has to run. The schedule moves with whatever has to happen first, like a scan or a permit. The written estimate lays out each part for your job, so you can see what you're paying for before anything gets cut.

When does a slab need cutting instead of a full tear-out?

  • One section sunk or broken

    The rest of the driveway or patio is flat and solid, but one piece has dropped or shattered, usually because the dirt under it washed out or was never packed. A clean saw line lets us take out just that piece, and if you wait, water keeps running under the edge and loosening the slab next to it.

  • A new line under the slab

    You're adding a drain, a gas line or power out to the yard, and the only path runs under concrete. A narrow saw-cut trench keeps the damage to a strip we can patch, while knocking a path through with a hammer tends to send cracks into concrete you meant to keep.

  • Water sitting against the house

    Puddles collect where the patio meets the wall after every rain, which usually means that part of the slab falls toward the house instead of away from it. Cutting out that strip to re-pour it or add a drain is a smaller job than dealing with water at your foundation winter after winter.

How we do concrete cutting

Before the saw starts, I walk the marked cut lines with you and we agree on every one, because a cut can't be put back. If the slab is post-tensioned, which means it was built with steel cables pulled tight inside it, we plan a scan first so we know where those cables run, and a big opening gets an engineer's look before we commit to it. We cut wet, with water fed to the blade so the dust stays down. We keep the gray slurry out of the gutter and away from the storm drain, and Bay Area guidance asks for sand bags in the gutter to block its path. Then we break out the cut piece, haul it off and clean up, so what's left is a straight edge ready for whatever comes next.

A cut is often the first half of a bigger job. When a sunken stretch comes out of a driveway, we pour it back as part of concrete driveway building. That's where I'll tell you to spend on the base, the dirt and rock the slab sits on, dug out and packed, before you spend on a fancier surface, because the base is usually what failed the first time. A trench across a patio, or a patio that's getting bigger, leads into concrete patio construction, with the new section sloped so water runs away from the house.

  1. Slab sawing and breaking out

    For driveways, patios, garage floors and walkways, a flat saw runs along the marked line so a section, a trench or an opening comes out with straight edges. It suits most home jobs, and it's the right cut when you're replacing part of a slab and want the new pour to meet the old one cleanly.

  2. Wall sawing and core drilling

    Wall sawing cuts openings in foundation or retaining walls, and core drilling bores round holes through a slab or wall for pipes, vents or wiring. Both take more setup than flat sawing, so they suit jobs that need an exact opening in a wall or a single clean hole.

What happens when you call about concrete cutting in Walnut Creek?

Here's how a job runs from your first call to the final walk-through, who does what along the way, and where the city's rules can move the date.

  1. Call or send a message

    Call (925) 532-0140 or use the form, and tell us where the cut is and whether it's in a slab or a wall. We'll set a time for me to come out.

  2. I look at the cut

    I look at the site, ask what the opening or trench is for, and check whether the slab looks post-tensioned. The written estimate breaks out the cutting, any scan or engineer's review, and the breaking and hauling, so you can see what each part costs before you decide.

  3. We line up permits first

    If the job needs a permit, a scan or an engineer, we get that lined up before we put you on the schedule. Walnut Creek requires an after-hours permit for construction on Saturdays and city holidays, so a weekday is usually the simpler date for a cut.

  4. We cut and walk it together

    My crew and I make the cuts on the lines you approved, break out and haul the concrete, and clean up the slurry. Then we walk the job with you so you can see the edges before we leave.

Concrete cutting, permits and the work around it in Walnut Creek

Walnut Creek requires a building permit to add a structure or physically change your property, while a private patio, driveway or path needs none, and a cut can land on either side of that line depending on what it opens up. Anything in the public right of way, like the sidewalk, the curb, the gutter or the driveway approach where your driveway meets the street, needs an encroachment permit from the city. The city's checklist for that permit asks every contractor and subcontractor on the work to hold a Walnut Creek business license. If your job needs a permit, I tell you at the estimate and we handle the application with the city or county office that covers your address.

Plenty of the driveways we cut into here meet the city sidewalk, so we set the cut line where your concrete ends and leave the city's side alone unless the permit covers it. Some newer houses sit on post-tensioned slabs, often with a warning stamped in the garage floor, and we see the same mix on jobs in Pleasant Hill and Lafayette.

Questions about concrete cutting in Walnut Creek

How much does concrete cutting cost in Walnut Creek?

Professional concrete saw cutting across the US usually costs about $4 to $25 per linear foot for the sawing itself. Wall sawing and cuts through reinforced or deeper slabs land toward the high end, and on a small job a minimum or setup charge for bringing the saw out can matter more than the per-foot rate. Your own figure comes on the written estimate after I've seen the cut.

How do I mark where I want my concrete cut?

Mark the cut lines you've approved, along with anything you know is buried near them, like a pipe or a drain, before the saw comes out. The concrete cutting trade group's specification puts that marking on the owner or the hiring contractor, so agree in writing who does it. Decide at the same time whether the saw may run past a corner, which is called an over cut.

Should my concrete slab be scanned before cutting?

Yes, if it's a post-tensioned slab, because industry repair guidance says to find the cables with ground-penetrating radar or another non-destructive test before cutting even small holes. Radar picks up metal more readily than plastic, which sends back a weaker signal, so ask the scanning crew how they handle plastic pipes or sleeves in your slab.

Do I need an engineer to cut a large opening in a post-tensioned slab?

Yes, the same guidance says to consult an engineer before a large opening, because a big cut interrupts several of the cables holding the slab together. Plan that review into your schedule and budget, since the engineer's answer decides whether the opening can go where you want it.

Who is allowed to do concrete cutting in California?

California's Contractors State License Board lists concrete sawing, breaking and coring under its D-6 Concrete-Related Services classification. Check any contractor's license with the board before they cut, and ask for proof of insurance too.

How long does concrete cutting take?

The sawing is usually the shortest part of the job, and most of the wait comes from what has to happen first. A post-tensioned slab needs a scan booked, a big opening waits on the engineer, and a cut at the sidewalk or curb waits on the city's encroachment permit. I tell you at the estimate which of those apply to your job.

  • Concrete driveway building

    When the cut takes out a sunken or broken section, the new pour needs a dug-out, packed base and joints placed where cracks should go.

  • Concrete patio construction

    If a drain trench or a bigger footprint means cutting into your patio, we pour back a surface that drains away from the house.
