What does it take to cut concrete at your house?
Concrete cutting in Hayward is the sawing, breaking and coring work that takes out a section of slab, opens a trench for a new line or puts a clean hole through, so the rest of your driveway, patio or floor stays in one piece.
Most people who call about a cut already have a spot in mind. It might be a broken panel in the driveway, a sewer or electrical line that has to get under the patio, or a sidewalk square that lifted. The price moves with how long and how deep the cut runs, how much steel is in the slab, whether a scan comes first and how much broken concrete has to go. The schedule mostly turns on whether the cut touches the public sidewalk or street, because that brings in a city permit. If new concrete goes back in, that part runs like any other flatwork, the flat slabs on the ground we pour for walks and patios, and a sidewalk square out front is the same work as concrete sidewalk building. I'll look at your slab and write up an estimate for your exact cut.
How do you know a section of concrete needs to be cut out?
A broken or lifted panel
One square of the driveway or walk has cracked through or tipped up at an edge, usually from roots, settled ground or water underneath. Cutting it out on clean lines lets you replace that panel alone, and if it waits, the trip edge grows and the cracks can spread into the squares beside it.
A new line under the slab
You need a sewer, water or electrical line run across a patio or garage floor, and the concrete is in the way. A straight cut opens just the strip the line needs, so the rest of the slab stays whole and the patch at the end stays small.
Water sitting against the house
Water that pools by the wall after every rain usually means a section tips toward the house or has nowhere to drain. Cutting out that section and pouring it back with the right fall fixes the slope, and the longer water sits there, the more it works under the slab and toward the foundation.
How we do concrete cutting, start to finish
Before we cut, I want to know what's inside the slab, so we ask for any drawings and set up a scan when cables or lines could be in there, because a saw can't tell steel from a power line. Then we mark the cut, often along an existing control joint, a line cut into the slab on purpose so it cracks there and not somewhere random, because a patch that meets an old joint holds better and looks cleaner. We keep water on the blade the whole time to hold down the dust, then break out the section, load it and haul it off.
Most cuts are the first half of a job. When part of a driveway comes out, the new piece goes in the same way it would with concrete driveway building, and an opening out back for a drain or a bigger slab ties into concrete patio construction. Either way, the part I won't rush is the subgrade, the dirt and gravel the patch sits on, because a nice finish over loose ground settles below its neighbors, and I'd rather your money go into the base than the surface.
Cutting out a section
Fits a cracked, lifted or badly sloped panel when the rest of the slab is sound, because you replace the bad piece instead of the whole driveway or patio.
Trenching for a line
Fits a new sewer, water or electrical run that has to cross concrete, because a narrow cut keeps the opening and the patch small.
Coring a hole
Fits a pipe, vent or post that has to pass through a slab or wall, because a round, clean hole leaves the concrete around it whole.

(510) 333-4444What changes concrete cutting in Hayward
If the cut reaches the public sidewalk or street, Hayward requires an encroachment permit, and the city's development services engineer decides what the job needs before we start. When your job needs one, we handle the paperwork and inspections with you and work with the city on its requirements.
Around Hayward we see a lot of older driveways and walks lifted by roots or cracked from settling, and plenty of cuts for new utility lines on houses being updated. The water we keep on the blade turns into a gray slurry, and state stormwater guidance says to keep it out of storm drains and creeks, so we contain it at the cut and clean it up before it can run down the driveway to the gutter. We handle the same kind of cuts on jobs in San Leandro and Castro Valley.
What happens after you call us about a cut in Hayward?
Send us the cut details
Call (510) 333-4444 or send the form with where the cut goes and about how long it runs, and we get back to you to set up a visit. If you have any building drawings, have them ready, because they tell us early whether a scan is needed.
I come out and look
I look at the slab, listen to what you want and write up an estimate that spells out the cut, any scan, the haul-off and any pour-back. You see what you're paying for and why before you decide anything.
We line up permits and scanning
If the cut is in the public sidewalk or street, the city typically takes five to ten business days to process the permit, or fifteen business days for the first review when traffic control is needed. We book the scan inside that same window so the cut can follow.
We cut, clean up, walk it
Our crew works inside Hayward's construction hours, 7 a.m. to 7 p.m. Monday through Saturday and 10 a.m. to 6 p.m. on Sundays and holidays. When the cut and cleanup are done, I walk the finished job with you.
Frequently asked questions
How much does concrete cutting cost in Hayward?
Professional concrete cutting usually costs about $3 to $10 per linear foot across the US. That's a national figure for the cutting, priced by the length of the cut, not a Hayward quote. Slab thickness, the steel inside, how deep the cut goes and how easy the spot is to reach move it, and a scan, a permit, hauling or new concrete add to the job.
Do I need a permit to cut a sidewalk or street in Hayward?
Yes, Hayward requires an encroachment permit for work in the public right-of-way, which includes public streets and sidewalks. The permit is Minor or Major depending on the area, how long the work runs and its scope, and Major applies to work zones over 500 linear feet or lasting more than two weeks.
How do I know what's inside my concrete slab before it's cut?
A ground penetrating radar scan shows what's inside before anyone cuts, picking up rebar, the steel bars that strengthen a slab, plus post-tension cables, conduits and empty pockets. One trade field guide advises treating any slab that might hold post-tension cables, steel cables pulled tight inside the concrete, as if it does until the drawings and a scan say otherwise. Pull out any building drawings you have and hand them to whoever does the cut.
What is the best way to keep dust down when cutting concrete?
Water on the blade is the usual answer, and a saw with a built-in system that feeds water to the blade limits how much silica dust gets into the air. It matters because dust from cutting, grinding or drilling concrete is fine enough to reach deep into the lungs, and worker safety guidance ties it to silicosis, a lung disease with no cure. It's fair to ask any crew how they'll keep it out of the air before you book.
What happens if a saw cuts a hidden cable or pipe in a slab?
Cutting a hidden cable or line can weaken the structure, hurt the person running the saw or flood the floor. A severed post-tension cable can cut into what the slab can carry and create serious safety hazards, a cut electrical conduit can electrocute the operator and a damaged water line can flood the space. That's why the drawings and the scan come before the blade.
What license does a concrete cutting contractor need in California?
California's contractor licensing board puts concrete sawing, breaking and coring under its concrete-related services class. So that's the license class that lines up with a cutting job when you're comparing contractors.
