Concrete Cutting in Wilmington NC

Concrete cutting in Wilmington NC for slabs, driveways, floors and walkways, with straight, clean cuts that protect the concrete you keep. Free written estimates.

  • Locally owned
  • Free estimates
  • Open daily 5 AM to 10 PM

Some jobs begin with a saw. A plumber needs a trench through a garage floor. A walkway has one bad panel that has to come out. A new door opening needs a clean edge. Smashing concrete with a hammer cracks the part you want to save, and a straight cut does not.

Coastal Concrete Wilmington does concrete cutting in Wilmington NC for homes and small businesses. We are locally owned, we explain each cut before we make it and we give a free written estimate.

Jobs that start with concrete cutting

Homeowners ask us to cut slabs for new drain lines, water lines and electrical conduit. They ask us to cut out a damaged driveway panel, a cracked corner or an old step. Builders ask for openings in floors and for control joints in new slabs.

A clean cut also gives new concrete a straight edge to meet, so the patch looks neat.

How a clean cut is made

We mark the line with chalk and walk it with you. A diamond blade and a stream of water make a narrow cut at the depth we need, and the water keeps dust down. Thick slabs may take more than one pass. Then we lift out the piece, clean the edge and protect the concrete around it.

Before any cut, we look for rebar, wire mesh, pipes and conduit, because a blade should never find them by surprise.

Safety, utilities and wet ground

Outside, we call NC811, which marks public utility lines for free, and we ask you about private lines for sprinklers, gas and lights. On a coastal lot, the water table can sit high, so a trench may fill with water. We plan for pumps and for the right moment to cut.

See concrete demolition, driveway repair and concrete repair for the work that often follows a cut.

Concrete cutting cost, timing and next steps

Price depends on how long and how deep the cuts are, how thick the slab is and how easy the area is to reach. Short cuts take an hour or two. A larger job can take a day. You get a written price after we see the job.

Concrete Cutting questions answered

Why use a saw instead of breaking the concrete out?

A saw makes a straight line and keeps the shock away from the concrete you plan to keep. When concrete is broken with a hammer, cracks can run well past the spot you meant to hit. That can turn a small fix into a big one. A cut edge also lets new concrete meet old concrete in a tidy joint.

Sawing costs a little more at the start, but it often saves money in the end. The patch looks better, it bonds better and it is less likely to crack. We use a saw along the edge of nearly every section we plan to remove, and we show you the marked line before we cut.

A short call about the job helps us tell you what concrete cutting in Wilmington NC will take before we come out to look at it. Ask us to show the planned line on the slab before we cut.

How deep can you cut a concrete slab?

Most home slabs are four to six inches thick, and our saws can go through them in one or two passes. Thicker floors take more time. Steel inside the slab slows the blade, but it does not stop it. We check the slab thickness first by looking at an edge, an old hole or a drawing.

We also look for steel and pipes before cutting. If we are not sure what is inside, we scan or start with a small test cut. Then we tell you how deep we plan to go and why. A plan on paper keeps the day calm and the cuts exactly where you and your plumber want them.

We mark every line with you first, so concrete cutting goes exactly where you and your plumber want it, and nothing is a guess. Tell us about any pipes or lines you know of, since a map or a photo from a past repair helps us plan a safe cut.

Is concrete cutting messy or loud?

It can be loud, because a saw blade spins fast. We wear hearing protection and try to work at hours that suit your neighbors. For dust, we use water on the blade, which turns dust into a slurry we clean up as we go.

Indoors, in a garage or a shop, we use a vacuum, cover doors and vents and move things aside. We keep doors open for fresh air. If someone in your home is sensitive to dust or noise, tell us when you call. We plan the work to keep dust low and to leave the space clean, so you can use it again the same day.

Dust control and noise planning are part of every concrete cutting job, and we are happy to talk through your needs before we start. Ask us how deep the cut will go and how we will clean the slurry, so you know the plan before the blade touches the concrete.

Can you cut a trench in my garage floor for new plumbing?

Yes, and it is one of the most common reasons to call. We mark the path with your plumber, cut both sides of the trench and remove the concrete between them. After the pipes go in, we fill the trench with the right base, add steel and pour new concrete that matches the floor.

A sloppy patch can leave a hump or a crack in your floor, so we tie the new concrete to the old with dowels or a bonding method and finish it to blend in. Your plumber and our crew can plan the schedule together, so the trench stays open for as short a time as possible. See concrete repair for how patches work.

A clean patch after concrete cutting depends on good steel, a firm base and a careful finish, and we handle all three on every job. Ask us to mark the cut for a second time with your plumber, because a clean cut in the right place saves hours of rework later.

How do you avoid hitting rebar or pipes inside the slab?

We start by asking you and by looking. Plans, edges, old holes and earlier repairs all give clues. Many slabs have wire mesh or rebar, and some hide conduit or pipes. When we are not sure, we use a scanner or make a small test cut first.

We also call NC811 for public lines outside and talk with you about private lines, like sprinklers and gas. If a cut must go through steel, we plan for it. Cutting rebar can be fine when it is done on purpose. We just do not want surprises. A careful look before the blade touches the slab protects your home and our crew.

Scanning and test cuts are small steps that make concrete cutting safer, and they can save you from costly repairs to pipes and wires. Tell us if the slab is inside a garage or a shop, and we will plan covers, a vacuum and fresh air so the space stays clean while we work on your cutting job.

Can you cut out one panel of a driveway or walkway?

Yes, and it is a smart way to save money. If only one panel has failed, we saw cut along the joints, break out that section and pour a new one. We tie the new panel to its neighbors with dowels, so it stays level and strong.

This works best when the panels beside it are still sound. If many panels are cracked or sunken, a full replacement may make more sense. See driveway repair and concrete driveway replacement. We look at the whole driveway, show you the options and give you a written price for each.

A single panel swap is often the smartest use of concrete cutting, and we will tell you plainly when that makes sense for you. Ask for a patch plan with the cut, since a good concrete cutting job ends with a neat patch that matches the slab and hides the trench.
