Serving Santa Rosa, CA and surrounding areas. (707) 867-4232
Adding a drain line, converting a garage, or removing a heaved driveway section all start with getting through the concrete cleanly. We scan for hidden utilities first, cut with diamond blades, control the dust, and handle permits so your next trade can get in on schedule.
Concrete cutting in Santa Rosa uses diamond-tipped saws and core drills to open precise lines through existing slabs, foundations, and walls for drain lines, utility access, ADU conversions, and damaged section removal. Most residential jobs take a few hours to a full day, with debris removed the same day the cuts are made.
The most common reason Santa Rosa homeowners call for concrete cutting right now is a garage conversion. California's push to allow accessory dwelling units has been enthusiastically adopted in Santa Rosa, and converting a garage almost always requires opening the slab to add bathroom plumbing. Older homes also generate steady demand for cutting because original cast-iron pipes under 1960s and 1970s slabs are reaching the end of their service life and need to be accessed and replaced.
Concrete cutting is rarely a standalone project. It is usually the first step before a plumber, electrician, or framing crew comes in. That means the quality of the cut directly affects how smoothly the next phase goes. For projects where the slab being opened is part of a larger concrete floor installation, coordinating the cut scope and finish before any work begins prevents having to do the same section twice.
Any time a plumber tells you they need to run a new pipe under your concrete slab, concrete cutting is part of the job. You will see this most often when adding a bathroom to a garage conversion, installing a floor drain in a laundry room, or connecting a new ADU to the city sewer. The concrete has to be opened cleanly so the pipe can be laid at the correct depth and slope.
In Santa Rosa, the clay soils under many older driveways expand and contract with the seasons, pushing sections up or letting them drop. When a section has moved enough to be a tripping hazard or to direct water toward your foundation, cutting out that specific section and replacing it is often cleaner and more lasting than patching. Stand at the end of your driveway and look along the surface; any section clearly higher or lower than its neighbors is a candidate.
Santa Rosa has seen a surge in homeowners converting garages into ADUs or in-law suites, and nearly every one of those projects requires cutting the garage slab to add plumbing drains. If you have started planning a conversion and your contractor has not mentioned concrete cutting yet, ask them directly. It is a step that gets missed in early estimates and then surprises homeowners later when the schedule slips.
When a plumber tells you there is a broken pipe under your slab, often discovered after a spike in your water bill or a wet spot on the floor that will not dry, the concrete above it has to be cut and removed to reach the pipe. This is one of the most common reasons homeowners in established Santa Rosa neighborhoods call a concrete cutting contractor, especially in homes built in the 1960s through 1980s where original cast-iron pipes are reaching the end of their service life.
We provide flat sawing for trench cuts across slab surfaces, core drilling for circular openings for pipes and conduit, and wall sawing for door and window openings in concrete walls. Every job begins with a utility scan to check for rebar and hidden lines before any blade starts. Debris removal is included in every quote; you will not find it showing up as a surprise line item on the invoice.
For ADU and garage conversion projects, we coordinate directly with your plumber before the cut so the trench depth, width, and slope are correct the first time. If the project involves replacing a section of concrete floor after the plumbing work is done, we can handle that through our concrete floor installation service so you are working with one crew from cut through patch and finish. For driveways where a section needs to come out and be replaced, that work flows naturally into our concrete driveway building service.
The Concrete Sawing and Drilling Association sets the industry training and safety standards our crews follow. For ADU work, we stay current with the City of Santa Rosa ADU permitting requirements so your project does not stall waiting on a permit correction.

Ideal for cutting door openings, window openings, or utility penetrations through concrete foundation walls or block.
Two forces are driving concrete cutting demand in Santa Rosa above what you would see in most comparable cities. The first is the ADU conversion boom. California's accessory dwelling unit laws have opened the door for Santa Rosa homeowners to convert garages and basements into rentable units, and the city has a dedicated permitting path to support it. Almost every one of those conversions requires opening the slab for plumbing. The second force is aging infrastructure. A large share of Santa Rosa's homes were built between 1950 and 1980, and the original cast-iron drain pipes under those slabs are now 40 to 70 years old. When one fails, the slab has to be cut.
The 2017 Tubbs Fire added a third layer. Homes rebuilt in Coffey Park, Fountaingrove, and other affected neighborhoods were poured to current California code, which means thicker slabs and more rebar than the older stock elsewhere in the city. Contractors who have only worked on pre-1980 slabs are sometimes caught off guard by the blade time and cost those newer pours require. We have worked in both the rebuilt neighborhoods and the older parts of Santa Rosa and adjust our approach and estimates accordingly.
We serve concrete cutting customers throughout Santa Rosa and nearby communities including Petaluma, Rohnert Park, and Novato. Clay soil conditions and post-fire rebuilding activity affect all of these communities in ways that shape how concrete cutting projects are scoped and priced.
We reply within 1 business day. Tell us where the cut needs to happen, roughly how long or wide, and why you need it. Most concrete cutting contractors need to see the job in person before committing to a firm price, because slab thickness and what is inside it change the cost significantly.
The estimator measures the area, assesses the concrete, and checks for steel reinforcing bars or utilities with a handheld scanner. You get a written estimate covering all work, debris removal, and any permit fees. A good contractor explains what could change the price if anything unexpected is found mid-cut.
If your project involves cutting into a structural element or adding plumbing, we handle the permit application with the City of Santa Rosa before work starts. This step usually takes a few business days to a couple of weeks. The permit fee appears as a line item on your invoice.
The crew sets up dust control, marks the cut lines, and makes the cuts with diamond-blade saws. Debris is removed and the area is cleaned. If a permit inspection is required, we coordinate that appointment before any patching or backfilling so the next trade can get in without delay.
We scan before we cut, handle the permits, and coordinate with your plumber so the job moves forward on schedule. Free written estimate, no pressure.
(707) 867-4232We check for hidden pipes and rebar with a handheld scanner before any blade touches your slab. In Santa Rosa's older neighborhoods, utility layouts often do not match original blueprints, and a cut that hits a hidden line creates a far bigger problem than the one you called about.
Our C-8 Concrete Contractor license is searchable on the CSLB website before you sign anything. Every job carries liability insurance and workers' compensation, and we pull the permits the city requires rather than skipping steps to save time.
We have cut slabs for garage conversions and in-law suites throughout Santa Rosa and are familiar with the city's ADU permitting process. We coordinate directly with your plumber so cut locations, depths, and slopes are right the first time.
We use water-fed blades and vacuum systems on every project to keep fine concrete dust from spreading through your home or property. In a city where many homeowners have already dealt with fire-related cleanup, the last thing you need is a new layer of dust settling into your living space.
Concrete cutting in Santa Rosa is not complicated when it is done by a crew that knows the local permit requirements, understands what is likely inside the slab based on the age and location of the home, and coordinates with the next trade before the first cut is made. That preparation is what keeps your project on schedule and on budget.
Once the cutting and plumbing work is done, a fresh concrete floor installation closes the trench and brings the surface back to a finished, level state.
