How do you cut concrete without hurting the rest of the slab?
Concrete cutting means sawing, coring or breaking out concrete that's already in place. In Piedmont we use it to open a slab or a wall cleanly, so the concrete around the cut stays sound and ready for whatever comes next.
Most people call because something has to go through concrete that's already there. It might be a new drain line under a garage floor, a doorway in a basement wall, or a cracked piece of driveway that has to come out before a new pour. The price moves with how long and how deep the cut runs, how thick the concrete is and what's inside it, whether we're working indoors, and how easily we can get a saw to it. The schedule mostly turns on whether a scan or a city permit has to come first. I'll give you your own figure in a written estimate once I've seen the site.
How we handle concrete cutting, start to finish
Before anything is marked, I ask where the cut sits, whether it's indoors and whether you have any drawings of the slab, because those answers decide the saw and the prep. If cables could be inside, we want the slab scanned first. Then we set up for water, dust and slurry so the mess stays out of your house and away from the storm drain. After that we mark the line, make the cut, break out and haul away what comes loose, and clean up. It works like prep in a kitchen, where the setup before the knife comes out decides how the plate turns out, and a cut in concrete can't be taken back once it's made.
Cutting is often the start of a bigger job rather than the whole of it. When a damaged section of driveway comes out, the new piece goes in as part of our concrete driveway building work, and when a patio needs a clean edge to grow from, we carry on with concrete patio construction.
Trenches for drains and lines
This suits a homeowner adding plumbing, a drain or a conduit under an existing slab. We keep the trench narrow and straight so the patch afterward is small and the rest of the floor stays put.
Removing a damaged section
If one part of a driveway, walk or patio has cracked or sunk, cutting it out lets you replace that piece instead of the whole slab. A straight saw line gives the new concrete a clean edge to meet.
Doorways and wall openings
This is for a new door, window or passage through a concrete or basement wall. These cuts take the most planning, because what's inside the wall and what the wall holds up both matter.
What concrete cutting in Piedmont involves
The City of Piedmont issues building permits and says most construction projects and repairs need one, with the application made online. The city keeps separate contacts for building permits and encroachment permits, and if you're not sure which one applies, it asks you to call its permit line at (510) 420-3050. Its guidance doesn't settle every cutting job on its own, so we don't assume either way. When a job needs a permit or a city review, we handle the application and the paperwork and tell you up front which office it goes through, and if it isn't clear, we check with the city before we start.
Water is the other thing we plan for here. Bay Area stormwater agencies warn that cutting slurry can run through storm drains to local creeks, where it can harm wildlife, clog drains and cause flooding. Their guidance is to block the path to the nearest drain with sandbags or something like them before the saw starts. The state's construction silica rule also calls for walk-behind saws to have a built-in system that keeps water feeding the blade. That's why water and drain protection are part of how we plan cuts here, and on jobs in Oakland, Berkeley, Alameda and the other East Bay cities we work in.
Why Piedmont homeowners call Piedmont Advanced Concrete for concrete cutting
The owner measures every cut
I come out to look at every job and give the estimate myself, then work on site with our crew. The person who planned your cut is there when it's made.
Licensed and insured in California
We're licensed and insured. The state licensing board lists concrete sawing, breaking and coring under its concrete-related license, so it's a fair question to put to anyone who offers to cut your slab.
Trained on an East Bay crew
We've been in business since 2020, and I learned the trade on a finishing crew here in the East Bay after years in restaurant kitchens. The kitchen habit of setting up before you start is how we treat a cut that can't be undone.
Thank you for considering us. When you're ready, tell us about your cut and I'll set up a time to come and look.

Frequently asked questions
How much does concrete cutting cost in Piedmont?
Professional concrete cutting across the US usually costs about $3 to $10 per linear foot. That's a national figure for the market, not our price. Your own number comes in the written estimate I send after measuring the cut and looking at access.
Do I need a permit to cut concrete in Piedmont?
Many cutting jobs do, and we confirm yours with the city before any work starts, as the Piedmont section above explains. If you'd like to check yourself, the city's permit line can tell you whether you need a building permit or an encroachment permit.
How do I know which saw my concrete cut needs?
Start with where the cut sits. One contractor's rule of thumb puts a slab saw on flat surfaces like floors and driveways and a wall saw on vertical openings, with a wire saw for concrete that's thick, reinforced or hard to reach. That's why the location of your cut is the first thing I ask about.
What is the best way to cut concrete inside a house?
One contractor's guide says electric slab and wall saws are best indoors or where people are home, because they give off no exhaust. If your family stays home during an indoor cut, an electric saw is the stronger choice. We also plan where the water and dust go so they stay out of the rest of the house.
Is it safe to cut a concrete slab that has cables inside?
Not without finding the cables first. Post-tension cables carry stored force, and cutting one can damage the structure or release that tension near the people working, so one scanning firm advises reviewing any post-tensioning records and having the slab professionally scanned before cutting. The same firm says drawings and visual clues help but can't establish clearance by themselves, and a scan can also help find rebar, the steel bars that reinforce concrete, and buried conduit.
Is the dust from cutting concrete dangerous?
It can be. The state's workplace safety agency calls respirable crystalline silica, a fine dust you can breathe in, a known carcinogen that can cause silicosis, an incurable and frequently fatal lung disease. That's why water and dust control are planned before the saw starts, as covered above.
Work that often comes after a cut
Concrete driveway building
When cutting takes out a cracked or sunken driveway section, the replacement needs a packed base and a proper pour so the new piece sits level with what stays.
Concrete patio construction
If you're widening a patio or replacing a worn corner, a clean saw line gives the new slab a straight edge to meet, and we can plan the pour from there.
