Shut the water off first, then call. The main shutoff is usually where the supply line enters the house or near the water heater, and closing it turns an expanding problem into a fixed one. If water is anywhere near outlets or appliances, cut power to that area at the breaker panel. Then open a faucet at the lowest point in the house to drain the lines.
That order matters more than anything else you do before a technician arrives. Water damage keeps spreading while you wait, and most of what makes a burst line expensive happens in the hour before the water stops.
When you call, you reach a live technician rather than an answering service queue, at any hour. Our emergency plumbers in Charleston run 24 hours a day, 7 days a week, and in Charleston we explain the visit cost before dispatching anyone, so the first thing you hear is a plan rather than a surprise.
Charleston housing stock fails in patterns you do not see inland. Peninsula houses sit on old cast iron and galvanized supply lines, the water table is high enough that sewer laterals take root intrusion early, and salt air corrodes outdoor condensers faster than the same equipment ages in the Midlands. Knowing which of those you are dealing with usually decides whether a repair holds.
Galvanized supply piping is the one homeowners meet first. It scales from the inside, so pressure drops room by room over years rather than all at once, and a house that has "always had low pressure upstairs" is often describing pipe that has closed to a fraction of its bore. Cast iron drain stacks fail differently: the bottom of the pipe channels out while the top looks intact, which is why a camera in the line tells you more than any amount of guessing from the fixture.
Outside, the ground works against you. Live oak and palmetto roots find sewer laterals through joints that have shifted in soft, wet soil, and the first symptom is usually a tub that gurgles when the washing machine drains. A sewer camera inspection shows whether you are looking at roots, a belly in the line, or a break, and those three have very different answers. Where a line is genuinely failed, sewer line replacement is a planned job rather than an emergency, and it should be priced that way.
The same climate that eats pipe is hard on equipment. Air conditioners here run more hours in wetter air than almost anywhere in the country, condensate drains clog because the system pulls real volume out of that air all season, and coastal condensers corrode. That is why AC repair and annual maintenance matter more on this coast than the manufacturer's schedule suggests.
In the Charleston area, one company covers both trades: plumbing, air conditioning, heating, heat pumps and ductless systems, 24 hours a day. That matters on the calls where the two overlap, like a condensate drain backing up into an air handler, or a gas line feeding both a water heater and a furnace. You are not coordinating two contractors and two schedules to fix one problem.
On the plumbing side we cover emergency plumbing, drain cleaning, water heaters including tankless repair, sewer work, gas piping, and the everyday plumbing repairs that make up most of what we do. On the HVAC side we cover AC repair, AC installation, heating installation, heat pumps and ductless mini splits, with emergency HVAC at any hour. We also work with property managers and business owners on commercial plumbing and commercial HVAC.
Our Columbia operation is different, and it is worth being straight about it. In Columbia and the Midlands we are a plumbing company only. If you need heating or cooling work there, we will tell you that plainly rather than send someone who cannot help you.
Free estimates are available on HVAC installations, financing options exist, and AC installations come with extended warranties and a 100% customer satisfaction guarantee. In most cases we can install the next day.
Blue Collars is a family-owned and operated plumbing and HVAC company working out of North Charleston, licensed in South Carolina under CLM.117414, answering both trades 24 hours a day across the Charleston area and plumbing across the Midlands. Pricing is upfront and flat-rate, quoted before any work begins, with no hidden fees.
Four things decide most of these calls, and they are worth stating plainly.
Family-owned means the person who answers cares how the job goes, because the name on the truck is the name on the business. Whether you need a quick repair or a full system installation, you can count on us to get the job done right.
Ask four questions, and you will sort a good contractor from a bad one before anyone is in your house. What is the license number? What does the visit cost, and when will I know it? Is the price flat-rate before the work starts, or hourly and open-ended? And who actually shows up, an employee or a subcontractor?
The license question is the cheapest protection you have. South Carolina publishes a contractor license lookup, so a number you can verify in thirty seconds is worth more than any badge on a website. Ours is CLM.117414.
The pricing question separates most companies. Flat-rate quoted before work begins means you approve a number, not an estimate that moves while a meter runs. Ask when you will hear the visit cost, and whether after-hours work changes anything, because the honest answer varies by company and by market. Ours is published: in Columbia there are no emergency or after-hours fees, and in Charleston we explain the visit cost before we dispatch.
Then ask what happens if the diagnosis changes. On older Charleston houses it sometimes does, because a camera finds a broken lateral behind what looked like a simple clog. What you want is a company that stops, shows you, and re-quotes, rather than one that keeps working and hands you the difference at the end.
Two operations, two service areas, and they are not the same. In the Charleston area we provide both plumbing and HVAC. In Columbia and the Midlands we provide plumbing only. Full coverage is listed on our areas we serve page, and each city has its own page for the trade we offer there.
Columbia plumbing runs out of Cayce and covers the same 24-hour schedule, with no emergency or after-hours fees. If you are in the Midlands and need heating or cooling, we will say so rather than sending a truck.
Yes. Blue Collars answers plumbing and HVAC calls 24 hours a day, 7 days a week, and you can speak with a live technician when you call. In the Charleston area that covers plumbing, heating and air conditioning. In Columbia and the Midlands, the 24-hour service is plumbing.
It depends on the job, so any figure quoted before anyone has seen the problem would be a guess. What we publish is how pricing works: upfront, flat-rate pricing before any work begins, with no hidden fees. In Charleston, we explain the visit cost before dispatching a technician, so you know where you stand before anyone arrives.
It depends on where you are. In Columbia there are no emergency or after-hours fees, so nights, weekends and after-hours plumbing cost the same as a weekday. In Charleston, the visit cost is explained before a technician is dispatched, so you hear about any charge before anyone is on the way.
Shut off the water at the main valve, usually where the supply line enters the house or near the water heater. If water is near outlets or appliances, switch off power to that area at the breaker panel. Open a faucet at the lowest point of the house to drain the lines, move valuables out of the way, then call a plumber. Water damage keeps spreading while you wait.
In the Charleston area, yes: plumbing, air conditioning, heating, heat pumps and ductless mini splits from one company. Our Columbia and Midlands operation is plumbing only, so if you need heating or cooling work there, we will tell you that plainly rather than send someone who cannot help.
Blue Collars is a licensed South Carolina contractor, license CLM.117414, shown in the footer of every page. Our technicians are background-checked and drug-screened. If you want to check any contractor's license before they work in your home, the South Carolina Department of Labor, Licensing and Regulation publishes a public license lookup.

Have them close the cold water valve on top of the heater, then switch off the breaker for an electric unit or turn the gas control to off for a gas unit. A pan or towels under the leak limits the damage. A leaking tank or relief valve will not fix itself, so book a visit by phone or online. In Charleston, the visit cost is explained before a technician is dispatched.
