Whether this is your first plumbing repair or your tenth, you deserve a plumber who shows up on time, explains what is going on, and gets the work done right. DMC Heating Cooling Plumbing is a family-run plumbing business based in Mt Holly, North Carolina, serving homeowners, landlords, and commercial clients across Gaston County. We handle everything from a dripping faucet to a full repipe, and we do it with the care and honesty you would expect from someone who lives and works in the same community you do.
We're a local crew, and we answer when you call.
Pick the date. We do the plumbing. We clean up after.
One call brings a plumber to your door.
Our plumbers know the homes and pipes in this area, and that local knowledge shapes how we work. We launched in 2024 with a straightforward goal: bring reliable, honest plumbing service to Mt Holly and the surrounding Gaston County communities. Two years in, most of our new customers come from neighbors recommending us to neighbors, and that is exactly the kind of business we set out to build.
Gaston County has a mix of older homes with aging pipe systems and newer construction that comes with its own set of demands. We work across all of it. Whether you own a home built decades ago with original plumbing or a newer property that needs updated fixtures and water heater service, we approach every job the same way. We treat your home and its pipes the way we would our own.
That same approach carries over to our commercial clients. Property managers, landlords, and small business owners call us when they need a plumbing contractor who can schedule reliably, communicate clearly, and get the job done without creating more problems than they solve.
We'll make your plumbing sound again.
What sets our plumbers apart is straightforward: we cover the full range of residential and commercial plumbing work, and we keep you informed from diagnosis to final test. You will always know what we found, what needs to be done, and what it will cost before any work begins.
Our everyday services cover the plumbing needs that come up in every home and business. Drain cleaning and clog removal, including hydro jetting for stubborn or recurring blockages, keeps your drains flowing and your main line clear. Leak detection and repair addresses hidden leaks, water line damage, and pipe failures before they turn into costly water damage. Water heater repair and replacement covers both traditional tank units and tankless water heater installation, so you are not left without hot water longer than necessary. We also handle toilet repair and replacement, faucet repair and installation, shower repair, sink installation, garbage disposal installation and replacement, and full fixture upgrades.
For larger work, we perform sewer and main line service, including sewer backup repair and sewer line cleaning. When a home's pipe system has reached the end of its useful life, we do full repiping using copper or PEX, depending on what the job calls for. All work is performed by licensed plumbers and meets the code requirements for Gaston County and the state of North Carolina.
Let us handle the plumbing and the permits.
A slow drain is easy to ignore until it becomes a full backup. Main line clogs are more serious than a simple sink blockage because they affect every drain in the building at once. We clear drain clogs at every level, from individual fixtures to the main sewer line. For heavy buildup or root intrusion, hydro jetting breaks through blockages that snaking alone cannot clear. Sewer camera inspection lets us see exactly what is going on inside the line so we address the actual problem, not just the symptoms. A sewer backup can mean sewage in the home, so fast attention matters.
A leak inside a wall or under a slab can go unnoticed for weeks and cause serious damage before it is found. We use leak detection methods that locate the source without tearing apart your home unnecessarily. From there, we repair or replace the affected pipe, whether that means a section of water line or a full burst pipe repair. Getting to the source of the leak quickly is the difference between a manageable repair and a much larger problem.
No hot water is one of the most disruptive plumbing problems a household faces. We repair water heaters when repair makes sense and replace them when it does not. That includes traditional tank water heaters and tankless units, which are increasingly common in both new and remodeled homes. If your water heater is not working, or if you want to upgrade to a more efficient system, a quick call gets you a quote and a scheduled visit.
A running toilet wastes water and money. A leaking faucet is a slow drain on both. We repair and replace toilets, fix and install kitchen and bathroom faucets, and handle full fixture upgrades for remodels and renovations. Garbage disposal installation and replacement rounds out the kitchen plumbing work we do regularly. These are the everyday jobs that keep a home running smoothly.
Your time matters, so we keep the plumbing job on schedule, and when an emergency hits, we move fast. Burst pipes, sewer backups, no hot water, and major leaks cannot wait for a regular business-hours appointment. We are available for after-hours calls, weekend service, and same-day scheduling when the situation calls for it.
We do not over-promise on response times because real emergencies vary, but we do commit to picking up the phone, giving you a straight answer about availability, and getting a plumber to your door as quickly as we can. If water is actively damaging your home or your business, call us first.
Reach out and we'll start at the source of the leak.
Residential customers come to us for everything from a single leaking faucet to a whole-home repipe. We work on bathroom remodels, kitchen plumbing updates, water pressure problems, shutoff valve repair, sump pump installation, and well pump service. If your home has older pipes or a history of plumbing issues, we can assess the full system and give you an honest picture of what needs attention now and what can wait.
On the commercial side, we work with property managers, landlords, and business owners who need a plumbing contractor they can count on for drain cleaning, water heater installation, repiping, and plumbing for rental properties. We understand that a plumbing problem in a rental or commercial space affects tenants and operations, so we schedule around your needs and communicate clearly at every step. We also handle backflow preventer installation and backflow testing for commercial clients and properties where that work is required.
For new construction and renovation projects, we provide rough-in plumbing and work alongside general contractors to keep the build on schedule.
Every service call follows the same process. We arrive, assess the problem, and explain what we found in plain terms. Before any work begins, you receive a clear quote that covers the job. If something unexpected comes up during the repair, we stop and talk to you before moving forward. There are no surprise charges added after the fact.
Questions about what a water heater replacement costs, or what repiping a house runs, are common and reasonable. Those numbers depend on the specifics of your home and the work involved, and the best way to get an accurate answer is to call for a quote. We would rather give you a number based on your actual situation than a ballpark that turns out to be wrong.
Plumbing repairs and installations are an investment in your home or property. We think you deserve to know exactly what you are paying for.
We are based in Mt Holly and serve the surrounding area throughout Gaston County. Our regular service area includes:
If you are in the area and are not sure whether we cover your location, call us and we will let you know.
We have been working in Mt Holly and across Gaston County since 2024, and that time on the ground means we know the neighborhoods, the housing stock, and the kinds of plumbing problems that come up most often here. Whether a job is in an older home near the center of town or a newer build on the outskirts, we arrive with relevant experience. That local knowledge shapes how we diagnose and approach every job.
Yes. We are a family-run plumbing business, and the people who answer the phone are connected to the same crew that does the work. You are not talking to a separate scheduling department or a remote operator. When you call, you reach someone who actually cares about how your job turns out.
We're a local crew, and we answer when you call. We are personally accountable for every job we take on, and our reputation in the community depends on doing the work right. Most of our new customers come from neighbors recommending us to neighbors, and that is the kind of business we set out to build.
Call us and we will come back to look at it. We are not satisfied with a repair that does not hold, and we stand behind the work we do. If the problem turns out to be something we missed, we address it.
We keep you informed from diagnosis to final test. That means we explain what we found before we start, let you know if anything changes during the work, and walk you through what was done when the job is complete. You should never be left wondering what happened inside your walls or under your floor.
Our plumbers look past the visible symptom to find where the problem actually starts. A water stain, a spike in your water bill, or a slow drain can each point to several different root causes. We take the time to trace the source before opening anything up, which limits unnecessary disruption and makes sure the repair actually solves the issue.
We stand behind the work we perform. If a repair we completed does not hold up, contact us and we will come back to make it right. We treat your home and its pipes the way we would our own, and that means we do not consider a job finished until it is working the way it should.
Yes. We operate 24 hours a day, seven days a week, including holidays and weekends. Burst pipes, major leaks, and no hot water do not wait for business hours, and we are reachable around the clock for exactly those situations. Call (980) 462-9795 any time.
We maintain our equipment as part of how we run the business. Showing up to a job with tools that are not ready wastes your time and ours. That same attention to preparation carries over into how we approach the work itself.

| Water Heater Repair and Replacement | tank water heater repair, tankless water heater repair, full unit replacement, commercial water heater service | Any property with no hot water, inconsistent temperatures, or a leaking unit | If your unit is more than ten years old and showing problems, replacement is often the more cost-effective answer |

| Water Pressure and Shutoff Valve Repair | pressure regulator diagnosis, shutoff valve replacement, water main shutoff repair, supply line repair | Homes with noticeably low pressure or shutoff valves that will not close fully | Corroded or stuck shutoff valves are a safety concern; replacing them before an emergency is worth the small investment |

How do I know if my water heater needs repair or full replacement?
Age and the nature of the problem are the two biggest factors. A unit under eight years old with a single issue, such as a faulty element or a thermostat problem, is usually worth repairing. A unit over ten years old that is leaking from the tank, producing rusty water, or failing repeatedly is often past the point where repair makes financial sense. When we look at the unit, we give you an honest read on which direction makes more sense for your situation.
What causes drains to clog and back up?
In kitchen drains, grease and food buildup are the most common culprits. In bathrooms, hair and soap residue accumulate over time and narrow the line. In main sewer lines, tree root intrusion, pipe scale, and debris are frequent causes. Older clay and cast-iron lines in Gaston County neighborhoods are especially prone to root problems. We identify where the blockage is before choosing the right clearing method.
What is the difference between drain snaking and hydro jetting?
A drain snake is a flexible cable that physically breaks up or pulls out a blockage near the drain opening. It is fast and effective for most common clogs. Hydro jetting uses high-pressure water to scour the inside of the pipe, removing grease, scale, and buildup along the full length of the line. For recurring clogs or lines that keep backing up, hydro jetting clears what a snake cannot reach and leaves the pipe in better condition going forward.
Upfront Quotes With No Surprise Fees
We give you a clear number before any work starts. If something changes once we are inside a wall or under the floor, we tell you before we proceed.
How are hidden leaks found without tearing up walls?
We trace the signs first: water stains, soft spots, warm floor sections, or a meter that keeps moving when no fixtures are running. From there, we narrow the location methodically before opening anything. For slab leaks, we follow the supply lines under the floor to find where pressure is dropping. This approach limits the area we need to access and keeps disruption to a minimum.
How do tree roots damage a sewer line?
Roots follow moisture and find their way into small cracks or loose joints in clay and older cast-iron pipes. Once inside, they grow and eventually block the pipe or break it apart. Established neighborhoods in Mt Holly have mature trees close to sewer lines, which makes this a common problem here. We clear the intrusion, inspect the line to assess whether the pipe itself has been damaged, and repair or replace sections where needed.
What are the signs of a sewer or main line problem?
The clearest sign is multiple drains backing up or draining slowly at the same time. A single slow drain usually points to a localized clog. When the problem affects every fixture in the building, the issue is typically in the main line. Other signs include gurgling sounds from drains, sewage odors inside the home, and wet or sunken areas in the yard above the sewer line.
Work Performed by Licensed Plumbers
Every job is handled by licensed plumbers who know North Carolina code and bring that knowledge to every visit, from a faucet swap to a full repipe.
What causes low water pressure throughout a home?
A failing pressure regulator is one of the most common causes. A partially closed shutoff valve, a corroded section of supply pipe, or a leak somewhere in the line can also reduce pressure. In older homes, scale buildup inside galvanized pipes gradually narrows the flow over years. We diagnose the cause rather than guess at it, so the repair addresses the actual problem.
How do estimates and pricing work?
We look at the job, explain what is involved, and give you a clear number before any work begins. If something unexpected comes up once we are inside a wall or under a floor, we stop and talk to you before proceeding. There are no charges added after the fact that we did not discuss with you first.
Same-Day and Emergency Availability
We take urgent calls seven days a week. For burst pipes, major leaks, or a sudden loss of hot water, we move as fast as the situation calls for.
Do I need to be home when the plumber comes?
For most jobs, yes. We walk you through what we found and what the repair involves before we start, and we need access to the affected area. If you are a landlord or property manager scheduling work at a tenant-occupied unit, we can coordinate access with whoever is on site. Just let us know the situation when you call.
When does a home actually need repiping rather than spot repairs?
Repeated leaks in different locations, consistently low pressure throughout the home, discolored water, or corroded pipe visible during other repairs are all signs that the pipe system as a whole has aged past the point of reliable spot fixes. Older Gaston County homes with original galvanized steel pipe often reach this point. We assess the condition of what is there and give you a straight answer about whether targeted repair or full repiping is the more practical path.
Is same-day service available, including on weekends?
Yes. We offer same-day appointments for urgent situations and take emergency calls seven days a week, including Saturdays and Sundays. When you call, we listen to what is happening and get a plumber to you as quickly as the situation calls for.
Call (980) 462-9795 and we will walk you through what the work involves and get a plumber scheduled for your property in Mt Holly or anywhere in the Gaston County area.
