One Call Plumbing: What to Know Before You Call

One Call Plumbing is a local South Carolina service that handles residential and commercial plumbing work

One Call Plumbing operates across South Carolina, responding to everything from burst pipes and water heater failures to routine maintenance and new installations. The company dispatches licensed plumbers to homes and businesses, typically arriving the same day or next day depending on demand and your location within their service area.

Like most plumbing contractors, One Call Plumbing charges for the service call itself, plus labor and materials. The initial visit fee covers the plumber's time to diagnose the problem; if you decide to move forward with repairs, that fee often applies toward the total cost. Rates vary by the complexity of the job, the time of day you call, and whether the work is emergency or scheduled.

Key Takeaways

• One Call Plumbing serves residential and commercial customers across South Carolina with same-day or next-day response times.
• You will pay a service call fee to have a plumber diagnose the problem, which typically credits toward repair costs if you hire them.
• Emergency calls outside normal business hours usually cost more than daytime appointments.
• Getting a written estimate before work begins protects you and clarifies what the final bill will cover.

How to reach One Call Plumbing and what information to have ready

Call their main line to schedule service or report an emergency. Have your address, phone number, and a description of the problem ready when you call—whether it's a leak, no hot water, a clogged drain, or something else. The dispatcher will ask how long the issue has been happening and whether water is actively leaking or backing up, since that affects how quickly they can send someone.

If you are calling during business hours, you can often schedule an appointment for a specific time window. After-hours emergencies (nights, weekends, holidays) go through their emergency line and typically carry a higher fee. Ask the dispatcher what that surcharge is before you confirm, so there are no surprises on the invoice.

Service call fees and what they cover

One Call Plumbing charges a service call fee to send a licensed plumber to your home or business to inspect the problem and give you an estimate. This fee is separate from the cost of repairs. In most cases, if you decide to hire One Call Plumbing to do the work, that call fee is deducted from your final invoice—so you are not paying it twice.

If you decide not to proceed with repairs, you still owe the service call fee. This is standard across the plumbing industry and covers the plumber's time, vehicle, and expertise to diagnose the issue. Ask the dispatcher for the exact amount when you schedule so you know what to expect.

Emergency versus scheduled appointments and pricing differences

Daytime appointments during regular business hours (typically Monday through Friday, 8 a.m. to 5 p.m.) are the least expensive option. Scheduled appointments give One Call Plumbing time to plan their route and staff accordingly, which keeps costs down.

Emergency calls outside those hours—evenings, weekends, and holidays—carry an additional surcharge. The exact amount depends on when you call and how far the plumber has to travel. A burst pipe at 2 a.m. on a Sunday will cost more than the same pipe bursting on a Tuesday afternoon. If your situation can wait until morning or the next business day, scheduling ahead will save you money.

Getting a written estimate before work begins

After the plumber inspects your problem, ask for a written estimate that breaks down labor, materials, and any other charges. This estimate should be specific—not just "fix leak, $500," but rather "replace 15 feet of copper pipe, $300; labor 4 hours at $60/hour, $240; solder and fittings, $50; total $590."

A detailed estimate protects you by making clear what the final bill will be before work starts. If the plumber discovers additional problems once they begin (a corroded fitting, mold behind a wall), they should stop and get your approval before proceeding. Never agree to work without knowing the cost first.

Common plumbing problems One Call Plumbing handles

One Call Plumbing responds to leaks under sinks, in walls, and at water heater connections; clogs in drains, toilets, and sewer lines; water heater failures and replacements; burst or frozen pipes; low water pressure; and running toilets. They also handle new installations for renovations and routine maintenance like drain cleaning and water heater flushing.

If your problem is outside their scope—such as septic system repair or well work—they can usually refer you to a contractor who specializes in that area. Do not hesitate to ask whether they handle your specific issue before scheduling, so you do not waste a service call fee on something they cannot fix.

How to prepare for the plumber's arrival

Clear the area around the problem so the plumber can access it easily. If the issue is under a sink, remove items from the cabinet. If it is a water heater in a closet or basement, make sure the path is clear and the space is well-lit. Have your water shut-off valve location identified—most plumbers will ask where it is, and knowing saves time if they need to stop the water flow quickly.

If you have pets, consider confining them to another room so they do not interfere with the work or escape when the door opens. Have your address clearly visible from the street so the plumber can find you without delay, especially important for emergency calls.

Frequently Asked Questions

Do I have to pay the service call fee if I don't hire One Call Plumbing to fix the problem?

Yes. The service call fee covers the plumber's time to diagnose the issue and provide an estimate. If you choose to hire a different contractor, you still owe that fee. However, if you do hire One Call Plumbing, the fee is usually credited toward your final bill.

How much more does an emergency call cost than a regular appointment?

The surcharge varies depending on the time of day and day of week. Call their emergency line and ask for the exact amount before you confirm service. This prevents surprises when the invoice arrives.

What if the plumber finds a bigger problem than what I called about?

They should stop work and explain the additional issue to you with a revised estimate. You are not obligated to approve extra work. Get it in writing before they proceed so you know the total cost.

Can I schedule an appointment online, or do I have to call?

Most plumbing companies require a phone call to schedule because the dispatcher needs to ask questions about your problem to determine urgency and send the right plumber. Check One Call Plumbing's website to see if they offer online scheduling or if a phone call is necessary.

What should I do if there is active water damage while I wait for the plumber?

Turn off the water at the main shut-off valve if you can locate it safely. Place towels or buckets under the leak to contain water and protect your floors and belongings. Take photos for your insurance company. Call One Call Plumbing back and let them know the situation has worsened—they may prioritize your call.
