What Does Concrete Cutting Involve?
Concrete cutting is the process of making controlled cuts through concrete using diamond-blade saws, core drills, and wall saws. Unlike breaking concrete with a jackhammer — which creates uncontrolled fractures and damages surrounding material — saw cutting produces clean, straight edges exactly where they are needed.
The most common reasons for concrete cutting in Portland are plumbing and sewer line access through basement floors, creating openings in foundation walls for egress windows or doors, removing damaged sections of sidewalks or driveways for replacement, and cutting control joints in freshly poured slabs.
Diamond-blade saws use water to cool the blade and control dust. The result is a precise cut with minimal vibration that does not disturb the surrounding concrete. After the cut section is removed, the opening is ready for whatever comes next — pipe installation, new concrete, window framing, or structural modification.
When Do You Need Concrete Cutting?
Concrete cutting is a service that supports other construction and repair work. Here are the most common situations in Portland.
Plumbing Access Through Basement Floors
Sewer line repairs, bathroom additions, and drain relocations in Portland basements frequently require cutting through the concrete floor to access the pipes below. Saw cutting creates a clean trench that can be patched neatly after the plumbing work is complete.
Egress Window Openings
Portland building code requires egress windows in basement bedrooms. Creating the window opening requires cutting through the concrete foundation wall — a precision operation that needs to be sized correctly and leave clean edges for the window frame installation.
Partial Slab Removal and Replacement
When a section of a driveway, parking lot, or sidewalk needs replacement, saw cutting defines a clean boundary so the new concrete meets the existing concrete at a straight, controlled joint rather than a jagged break.
Door Openings in Foundation Walls
Adding a walkout door to a basement, creating access to a crawl space, or widening an existing opening all require cutting through a concrete foundation wall. This work needs to account for the structural load above the opening.
Concrete Cutting Services We Provide
Concrete Cutting in Portland — Common Applications
Portland's housing stock creates steady demand for concrete cutting services. The city's older neighborhoods — Richmond, Buckman, Sunnyside, and Brooklyn — have homes with concrete basement floors and foundation walls that frequently need modifications for plumbing repairs, basement conversions, and seismic upgrades.
Basement bedroom conversions are one of the most common triggers for concrete cutting in Portland. Oregon building code requires egress windows in sleeping rooms, and most existing basement walls do not have openings large enough to meet the requirement. Cutting a window opening through an eight-inch concrete wall is precise, specialized work.
Commercial concrete cutting is also common in Portland's industrial areas. The Central Eastside, Northwest Industrial, and Columbia Corridor have warehouses and commercial buildings where concrete floors and walls need modifications for utility upgrades, equipment installation, and tenant improvements. The industrial-grade concrete in these buildings is often thicker and may contain rebar, requiring diamond-blade equipment with the capacity to handle reinforced material.
What Happens During a Concrete Cutting Project?
Site Assessment and Marking
We assess the concrete thickness, check for reinforcement and embedded utilities, and mark the cut lines. For wall cutting and core drilling, we identify structural reinforcement that must be avoided or accounted for.
Setup and Protection
The work area is prepared — surfaces are protected, water containment is set up for wet cutting, and access is arranged for the equipment. For interior work, we manage dust and slurry to keep the surrounding space clean.
Cut and Removal
The concrete is cut along the marked lines using diamond-blade equipment. For slab cuts, the cut sections are broken out and removed. For wall openings, the cut section is supported during cutting and removed as a unit when possible.
Cleanup and Handoff
Cut material is removed from the site. The opening or trench is cleaned and ready for the next trade — plumber, electrician, window installer, or our own crew for new concrete placement.

Why Portland Contractors and Homeowners Choose Us
Clean, Precise Cuts
Diamond-blade equipment produces straight, controlled cuts without the vibration and collateral damage of impact methods. The result is a clean edge that is ready for the next step — whether that is a patch, a window frame, or a pipe fitting.
Utility Awareness
Before cutting any slab or wall, we assess what is embedded or behind the concrete — rebar, post-tension cables, plumbing, electrical conduit, and gas lines. This prevents costly damage and safety hazards.
Dust and Slurry Management
Concrete cutting generates dust (dry cutting) or slurry (wet cutting). We manage both — containing slurry for interior work and using dust suppression methods where needed — to protect the surrounding space.
Coordinates With Other Trades
Concrete cutting is often the first step before a plumber, electrician, or window installer can begin. We schedule our work to fit the overall project timeline so the opening is ready when the next trade arrives.
Frequently Asked Questions
Costs depend on the cutting method, concrete thickness, total linear or square footage, and access conditions. Flat sawing is typically priced per linear foot. Core drilling is priced per hole based on diameter and depth. Wall sawing is priced by the square foot of opening. We provide exact pricing after assessing the job.
Yes. Diamond-blade saws cut through both concrete and reinforcing steel. Cutting through rebar increases blade wear and slows the process slightly, but it does not prevent a clean cut. We assess the reinforcement layout before cutting so there are no surprises.
Wet cutting — the standard method — uses water to cool the blade and suppress dust. The water creates a slurry that we contain and clean up. For situations where water is not practical, dry cutting with vacuum dust collection is used. Either way, we manage the byproducts to protect the surrounding space.
Any opening in a foundation wall needs to be structurally evaluated. Typically, a steel or concrete lintel is installed above the opening to carry the load that the removed wall section was supporting. This structural header design is specified by a structural engineer before the cutting begins.
