Need a drain channel, utility opening, or damaged slab section removed? We cut concrete precisely in San Luis Obispo - straight edges, proper cleanup, and no damage to the surrounding slab.
Concrete cutting in San Luis Obispo uses diamond-blade saws to slice through hardened slabs with precision - most residential jobs take two to six hours from setup to cleanup, and the cut is complete the moment the saw stops.
Homeowners contact us for a range of reasons: an ADU project that needs new plumbing through the garage slab, a patio that has cracked and needs a damaged section removed, or a driveway that needs a drainage channel cut before the next rainy season. Concrete cutting is also how you create a clean opening in a foundation wall when connecting two spaces. Unlike breaking concrete with a jackhammer, cutting leaves a straight, controlled edge that closes back up neatly.
If you need the existing slab replaced after the cut, our concrete driveway building and concrete retaining walls services can handle the rebuild from the ground up.
If you are upgrading a patio, adding an outdoor shower, or running a new water or electrical line under your yard, the concrete in the way has to be opened up cleanly. Jackhammering creates a rough, unpredictable opening - cutting gives you a straight, controlled slot that closes back up neatly once the work is done.
A crack that was hairline last year and is now wide enough to catch a coin on edge is telling you the slab is moving. In San Luis Obispo's clay-heavy soils, this kind of movement is common as the ground swells in the wet season and shrinks in the dry season. Cutting out and replacing the damaged section is often more durable than patching a crack that will just reopen.
Converting a garage to living space or adding an accessory dwelling unit almost always requires new plumbing and electrical connections through the existing slab. Concrete cutting is how those openings get made cleanly and safely. Given how many San Luis Obispo homeowners are pursuing ADU projects right now, this is one of the most common reasons local contractors get called.
San Luis Obispo's winter rains can reveal drainage problems that dry summers hide. If water sits on your concrete slab for hours after a storm, or pools against your foundation, cutting a drainage channel or relief opening redirects that water away from your home before it causes a more expensive problem.
We handle all types of residential and light commercial concrete cutting in San Luis Obispo. That includes flat slab cutting for drains, utility channels, and damaged section removal, as well as wall cutting to create clean openings in foundation walls or garage walls for new doorways and connections. Every job uses wet cutting - a steady stream of water cools the diamond blade and keeps silica dust from spreading through your yard or home. We manage the resulting slurry and clean the work area completely before leaving.
For ADU projects and permitted renovations, we coordinate directly with your general contractor or plumber to make sure the cuts are placed correctly the first time. The Concrete Sawing and Drilling Association publishes industry standards for safe cutting practices, and our crew works to those standards on every job.
Best for homeowners adding drains, utility lines, or removing a cracked section of a driveway, patio, or garage floor.
Suits any project that needs a clean opening in a concrete wall or foundation - garage conversions, new doorways, or utility access.
Ideal for homeowners adding an accessory dwelling unit or completing a permitted remodel that requires new utility connections through an existing slab.
Two trends drive a lot of the concrete cutting work we do in San Luis Obispo. First, the city's older housing stock - much of it built in the 1950s through 1970s in neighborhoods like the Anholm District and Old Town - has slabs that were poured without the steel reinforcement common in newer construction. That actually makes cutting easier and less expensive on older homes, but those same slabs may have settled unevenly over the decades, so a contractor should assess the slab in person before quoting. Second, San Luis Obispo has seen a significant increase in ADU construction driven by state housing laws and demand near Cal Poly, and nearly every ADU project requires concrete cutting to run new utility connections.
San Luis Obispo's clay-heavy soils also mean slabs in parts of the city have shifted or cracked more than in other California cities without hard freeze-thaw cycles. When cutting into a stressed slab, the right approach is slower and more deliberate to avoid widening existing damage. We serve homeowners throughout the city and in surrounding communities including Pismo Beach and Grover Beach, where similar soil and drainage conditions apply.
We respond within 1 business day to schedule a free on-site visit. Describe what you are trying to accomplish - a drain opening, a utility line, an ADU connection - and we will ask the right questions to show up prepared.
We look at the slab thickness, check for existing cracking or settling, and assess how easily our equipment can reach the work area. You get a written quote that spells out exactly what we'll cut, how long it will take, and what is included - including cleanup.
If your project is part of a permitted renovation - an ADU, a foundation modification, or a utility connection - we handle the permit application with the City of San Luis Obispo. We factor the permit review timeline into your schedule so there are no surprises.
The crew marks the cut lines, sets up water flow for dust control, and begins cutting. Before leaving, we clean up all slurry, rinse the work area, and walk the finished cut with you so you can confirm the edges are straight and clean.
We respond within 1 business day - no obligation. After you submit, someone from our office will call to schedule your free on-site visit and written quote.
(805) 269-8770San Luis Obispo has become one of the most active ADU markets on the Central Coast, and we have worked on concrete cutting for a significant number of those projects. We know what the city's building department expects, how to coordinate with other trades, and how to get the cuts right the first time so your project stays on schedule.
We work across 12 communities from San Luis Obispo down through Santa Barbara County. That range gives us hands-on experience with the soil conditions, slab types, and permit processes across the Central Coast - including the differences between how things get done in SLO versus Pismo Beach or Grover Beach.
The saws we use are purpose-built for concrete cutting with industrial diamond blades sized to your slab thickness. Using the wrong equipment is how surrounding concrete gets cracked during a cut. You can learn more about industry equipment standards through the{' '} Concrete Sawing and Drilling Association at csda.org.
Wet cutting produces a gray, watery slurry that can stain light-colored surfaces if it dries. We manage that slurry throughout the job and rinse the work area completely before leaving. If you have decorative pavers, a garden bed, or a drain nearby, tell us before we start and we will take precautions to protect them.
Every concrete cutting job we take on starts with an honest look at your slab. If there is a complication - an older slab with unexpected thickness, reinforcement we did not anticipate, or a drainage issue worth flagging - we tell you before the saw starts, not after.
