RJM Plumbing: What to Know Before You Call

RJM Plumbing is a licensed plumbing contractor serving the Midlands region of South Carolina

RJM Plumbing operates as a full-service plumbing company based in the Columbia area, handling residential and commercial work. The company holds the licenses required to operate in South Carolina and handles jobs ranging from routine repairs to new installations. Before calling any plumber, knowing what services they offer, how they price work, and what to expect during the visit helps you decide whether they're the right fit for your situation.

Like most plumbing contractors in South Carolina, RJM Plumbing charges for service calls, estimates, and labor. The cost of any job depends on what's wrong, how long it takes to fix, and whether parts need to be ordered or replaced. Understanding how plumbers in your area typically structure their pricing—and what questions to ask before work begins—protects you from surprises on the invoice.

What to ask before you schedule a visit

When you call RJM Plumbing or any contractor, have specific information ready: what's happening (water leak, no hot water, slow drain), where it's happening, and when it started. This helps the dispatcher give you an accurate timeframe and lets the plumber come prepared with the right tools and parts.

Ask whether the service call itself costs money, and if so, how much. Many plumbers charge a flat fee for the visit—typically $75 to $150 in the Columbia area, though this varies—and some credit that fee toward the bill if you hire them. Ask also whether they provide a written estimate before starting any work beyond the initial diagnosis. South Carolina law does not require plumbers to provide written estimates, but reputable contractors do, especially for jobs over a certain amount.

Confirm their service hours and whether they charge extra for evenings, weekends, or emergency calls. If your problem is urgent (a burst pipe, sewage backup), knowing the after-hours rate upfront prevents sticker shock later.

How plumbing costs are structured

Most plumbers charge one of three ways: a flat rate for common jobs (like unclogging a drain), an hourly rate for diagnosis and labor, or a combination of both. A flat-rate job might cost $200 to $400 to clear a clogged drain, while hourly work might run $75 to $150 per hour depending on the contractor and the complexity of the job. Parts—pipe, fittings, fixtures, water heaters—are billed separately on top of labor.

When you get an estimate, make sure it specifies what's included: labor hours, the parts needed, any disposal fees, and whether the price covers cleanup. If the plumber discovers additional problems once they start (for example, corroded pipe behind a wall), they should stop and get your approval before proceeding with extra work.

Verifying a plumber's license and insurance

South Carolina requires plumbers to hold a license issued by the Department of Labor, Licensing and Regulation (DHEC). You can verify a plumber's license status on the DHEC website by searching the contractor's name or license number. A valid license means the plumber has passed an exam and meets the state's standards for the trade.

Ask also whether RJM Plumbing carries liability insurance and workers' compensation insurance. Liability insurance protects you if the plumber damages your property during the job; workers' compensation covers the plumber if they're injured on your property. A contractor without these policies leaves you exposed to legal and financial risk if something goes wrong.

Common plumbing problems and typical costs

Drain cleaning—the most common call—usually runs $150 to $300 for a single drain, depending on how far down the clog is and whether the plumber needs to remove the trap or snake the line. A water heater replacement typically costs $800 to $1,500 for labor and the unit itself, though prices vary by the type and size of heater. Leak repairs range from $150 to $500 if it's a simple fix (tightening a fitting, replacing a washer) to $1,000 or more if the leak is in a wall or under the foundation and requires cutting into drywall or concrete.

Toilet repairs are often inexpensive—$100 to $250 to replace a fill valve or flapper—but a full toilet replacement runs $300 to $800 depending on the fixture. If you're facing a major repair, getting estimates from two or three contractors in your area gives you a sense of the market rate and helps you spot outliers.

What to expect during the visit

When the plumber arrives, they'll typically start by asking you to show them the problem and explain what you've noticed. They'll inspect the area, run water, listen for sounds, and may use tools like a camera to look inside pipes. This diagnosis phase is when they determine what's wrong and what it will cost to fix.

For simple jobs, they may fix it on the spot. For larger work, they'll provide an estimate and ask for your approval before proceeding. If they need to order parts or schedule a return visit, they'll give you a timeline. Keep records of any work done, parts replaced, and the invoice—these are useful if problems arise later or if you need to file an insurance claim.

When to call a plumber versus handling it yourself

Minor issues like a running toilet, a slow drain, or a leaky faucet can sometimes be fixed with basic tools and parts from a hardware store. However, if you're not comfortable working with water lines, if the problem is in a wall or underground, or if it involves the main water line or sewer connection, call a licensed plumber. Mistakes in these areas can lead to water damage, contamination, or code violations that are expensive to fix.

South Carolina's plumbing code requires certain work to be done by a licensed contractor and inspected by the local building department. If you're unsure whether your project requires a permit or a licensed plumber, contact your city or county building department before you start.

Frequently Asked Questions

How do I know if RJM Plumbing is licensed?

Visit the South Carolina Department of Labor, Licensing and Regulation website and search for the company name or the plumber's individual license number. A valid license confirms they've met the state's training and testing requirements. You can also ask the company directly for their license number when you call.

What should I do if I'm not satisfied with the work?

Contact the company within a reasonable time and describe the problem. Reputable contractors will return to fix defective work at no charge if the issue is their fault. If you can't resolve it directly, you can file a complaint with the South Carolina Department of Labor, Licensing and Regulation, which investigates violations of the plumbing code and contractor licensing rules.

Can I negotiate the price of a plumbing job?

You can ask, but most licensed plumbers price work based on materials, labor time, and overhead. What you can do is get multiple estimates and compare them. If one estimate is significantly higher or lower than others, ask why—it may reveal a difference in scope, quality of parts, or warranty.

Do I need a permit for plumbing work in my home?

It depends on the scope of work and your city or county's rules. Simple repairs like replacing a faucet usually don't require a permit. New installations, water heater replacements, and major repairs often do. Contact your local building department or ask the plumber—they know the local code and can tell you whether a permit is needed.

What's the difference between a plumber and a handyman?

A licensed plumber has passed a state exam and can handle any plumbing work, including work that requires permits and inspections. A handyman may handle minor repairs but is not licensed to do plumbing work that affects the water or sewer system. For anything beyond a simple fix, hire a licensed plumber to ensure the work meets code.
