Serving Mountain View, CA and surrounding areas. (650) 582-0077
Drain install, ADU rough-in, or damaged slab removal - we use diamond-blade saws, call 811 before touching the ground, and haul every piece of debris when we leave.
Concrete cutting in Mountain View uses diamond-tipped saws to slice through hardened slabs cleanly and precisely - creating openings for drains, pipes, and utility lines, or removing damaged sections without cracking the concrete around them - and most residential cuts take one to three hours of active work once the crew is set up, with a half-day visit being the norm when setup and cleanup are included.
Most homeowners call us because another trade - a plumber, an electrician, or a general contractor building an ADU - has told them the slab needs to be opened before the next phase of work can begin. In Mountain View, where the ADU construction surge has made concrete cutting a common early-project step, that coordination matters. Getting the cut wrong delays every trade that follows. If you are replacing a section of an older driveway or patio that has heaved or cracked from Bay Area clay soil movement, our concrete driveway building team can handle the replacement pour once the damaged section is removed.
We visit the site before quoting, assess the slab condition, confirm the utility situation, and give you a written estimate that covers everything - the cut, the debris removal, and the slurry cleanup. Call or message us and we will get back to you within one business day.
If water pools in your garage, laundry room, or patio and your plumber says there is no accessible cleanout, concrete cutting is likely the next step. The plumber needs an opening in the slab to reach the drain line, and that opening has to be cut - not jackhammered - to keep the surrounding concrete intact and usable.
Mountain View has seen a strong surge in ADU construction, and most of those projects require new drain lines, water supply lines, or electrical conduit to be run beneath an existing slab. If your contractor or architect has told you that new utility rough-ins are needed under the floor, concrete cutting is how that work begins.
Mountain View clay soils shift with California wet-dry cycles. When a section of concrete heaves or drops relative to the sections around it, the cleanest repair is often to cut out just that section and replace it - rather than patching over the surface, which rarely holds long-term. If you feel a lip between two driveway sections when you walk across, the slab has moved.
Many Mountain View homeowners are upgrading older garages for EV charging, workshops, or home gyms. Adding a floor drain where there is none requires cutting through the existing slab to install the drain body and connect it to the sewer line. There is no other way to do it cleanly.
We use diamond-blade saws for every residential cut - both walk-behind flat saws for larger slab areas and hand-held cut-off saws for tighter or more precise work. All cuts are done wet, with water flowing over the blade to cool it and capture silica dust, which protects both your home and our crew. Before any cut that involves breaking into the ground beneath the slab, we call 811 to have utilities marked - required by California law, and a step we take on every single job without exception. If your project involves a larger parking area or commercial surface, our concrete parking lot building team can assess the full scope when cutting is just one part of the work needed.
We assess the slab in person before quoting - checking thickness, looking for signs of rebar or post-tension cables, and confirming the cut location relative to utilities. Our quotes are written and cover the cut, debris removal, and slurry cleanup. Concrete chunks cannot go in a standard trash bin, and wet slurry cannot run into storm drains under local stormwater rules, so we haul everything away and dispose of it properly. The opening we leave is clean and ready for the next trade.
For plumbers, electricians, and general contractors who need a clean slab opening to install or repair drain lines, sleeves, or conduit runs beneath an existing floor.
Suited to Mountain View homeowners adding accessory dwelling units or converting garages where new utility rough-ins must be run under the existing concrete slab before framing begins.
For driveways, patios, or garage floors where a section has heaved or cracked beyond patching - we cut the boundary cleanly so the replacement pour integrates without visible seams.
For inside-the-home work where dust containment and slurry management matter - we lay protective sheeting, use wet-cutting throughout, and leave the surrounding area clean.
A large share of Mountain View's residential neighborhoods - particularly in the Cuesta Park, Rex Manor, and Old Mountain View areas - were built between the 1940s and 1970s. Slabs from that era were often poured thicker than today's standard, and some contain older reinforcing methods that require different blades and more cutting time. A contractor who quotes flat prices over the phone without asking about the home's age or slab condition is guessing - and a wrong guess affects the surrounding concrete and your project timeline. We assess the slab in person on every job before giving you a number. Homeowners in Palo Alto and Los Altos have the same mid-century housing stock and we bring the same on-site approach to every job across the South Bay.
Silicon Valley's decades of development also mean that underground utilities - gas lines, fiber conduit, water mains, and electrical runs - are layered beneath many properties in ways that are not always accurately mapped. Cutting through one of those lines without proper locating is expensive, dangerous, and avoidable. We call USA North 811 before every ground-involved cut, which is required by California law and takes a few minutes to arrange. Beyond utilities, local stormwater rules prohibit running concrete slurry into storm drains - we use wet-vacuum systems and haul slurry away rather than washing it off the driveway. For more on water use practices that apply to local cutting work, the Valley Water district publishes current guidelines for Santa Clara County.
We ask a few quick questions: what is the cut for, how large does the opening need to be, and do you know if the slab has steel reinforcing inside it. You do not need to know all the answers - a good portion of what we need, we determine during the site visit. We respond within one business day.
We come to the property, measure the cut location, check the slab thickness, and look for signs of rebar or post-tension cables. We also confirm whether a permit is needed for your specific project. After the visit, we give you a written quote that covers the cut, debris removal, and slurry cleanup - no line items left out.
If a permit is required, we coordinate with the City of Mountain View building department. In parallel, we call 811 to have underground utilities marked before any ground-involved work begins. Simple utility permits can sometimes be issued quickly; we give you a realistic timeline at the quote stage.
The crew marks the line, sets up the saw, and cuts with water flowing over the blade. Most residential cuts finish within one to three hours. We remove the concrete section, clean up slurry and debris, and leave the opening clean and ready for the next trade - plumber, electrician, or whoever is working the next phase.
We visit your property, assess the slab in person, and give you a written quote that covers everything - cut, cleanup, and debris removal - with no obligation to book.
(650) 582-0077We use diamond-tipped saw blades for all residential cuts - not older abrasive tools. Diamond blades cut cleaner, produce less vibration, and reduce the risk of cracking the concrete you want to keep. In Mountain View's older neighborhoods where slabs may already have hairline cracks, that precision is not optional.
We call for utility marking before any cut that involves breaking into the ground beneath the slab - every single time, without exception. Silicon Valley's layered underground infrastructure makes skipping this step genuinely dangerous. California law requires it, and we would do it regardless. The{" "}<a href="https://www.osha.gov/silica-crystalline" target="_blank" rel="noopener noreferrer" className="text-primary underline underline-offset-4 hover:text-primary/80">OSHA silica rules</a>{" "}that govern dust control on cutting jobs are another standard we follow by default.
Concrete cutting produces heavy chunks and wet slurry - neither can go in a standard trash bin, and slurry cannot run into storm drains under local environmental rules. We contain, collect, and haul away all of it. When we leave, the cut area is clean and the opening is ready for the next trade.
We do not quote concrete cutting over the phone without seeing the slab. Mountain View's older housing stock includes slabs that are thicker than standard and some that were reinforced differently than newer construction - a flat phone quote on a job like that is a guess. We assess in person so the price you agree to is accurate.
The combination of accurate in-person quotes, proper utility locating, dust and slurry management, and clean debris removal means the project that depends on our cut - the ADU, the drain install, the garage conversion - stays on schedule and on budget. That is what the trades working after us count on, and it is what you should count on too.
Once a damaged driveway section is cut out and removed, our driveway team pours the replacement panel to match the surrounding concrete.
