Drain Repair

Sometimes a slow drain isn't about buildup — it's about the pipe itself. Cast iron drain lines in older Charleston homes corrode from the inside out. Tree roots find their way into interior drain pipes through small cracks and eventually break through. Ground movement over time can crack or collapse a pipe running under a slab. When that happens, cleaning won't solve it — you need drain repair.

At Yeehaw Plumbing, we handle drain repair across Summerville, Charleston, and the surrounding Lowcountry. We start with a camera inspection to see what's actually going on inside the pipe, then walk you through your options — spot repair, section replacement, or full re-line — based on what the pipe actually needs.

Call (843) 509-6943 and we can usually get someone out same-day.

‍

Common Causes of Drain Pipe Damage

‍

Interior drain lines take a lot of wear over the years. Some of the most common causes we see in Lowcountry homes:

‍

• Corrosion in aging cast iron drain lines (very common in older Charleston-area homes)
• Root intrusion from nearby trees pushing into pipe joints
• Cracks or breaks from ground movement in sandy Lowcountry soil
• Collapsed pipe sections in old lines that have deteriorated
• Damage from foundation settlement or slab shifts
• Broken pipe joints or fittings after decades of pressure cycles
• Improperly installed pipe from a past renovation
• Damage from a nearby construction or landscaping project

If your home is more than 30 years old and the drain lines have never been evaluated, it's worth a camera inspection before problems get worse.

‍

Signs You May Need Drain Repair

‍

Drain problems that keep coming back — even after cleaning — usually point to something more than a clog. Warning signs to watch for:

‍

• Recurring clogs at the same drain or the same spot in the line
• Multiple drains slow or backing up at the same time
• Sewage smell coming from a drain or from under the house
• Wet or damp spots on floors, walls, or ceiling near plumbing runs
• Ceiling stain that grows or comes back after being painted over
• Gurgling sounds from drains that don't clear with a plunger
• Rodent or insect activity near drain pipes
• A drain that just won't clean out no matter what's done to it

If any of this sounds familiar, cleaning likely isn't going to solve it. A camera inspection will tell you what you're actually dealing with.

‍

Our Drain Repair Process

‍

Every drain repair call starts with figuring out what's actually broken and where. We use a camera to see inside the pipe rather than guessing.

‍

Our process:

‍

• Camera inspection to locate the damage and see its extent
• Explain what we found — cracks, collapses, root intrusion, corrosion
• Discuss options: spot repair, section replacement, or full re-line
• Give you upfront pricing before any work starts
• Access the pipe with the smallest opening we can (through drywall, ceiling, crawl space, or slab)
• Make the repair using pipe that matches your existing system (typically PVC for modern drain lines, ABS or cast iron for older systems)
• Test the repair before closing anything up
• Show you what we did and what we found along the way

‍

If the damage is widespread and repair costs are stacking up, we'll show you the numbers on repair versus full replacement of the line so you can decide what makes sense.

‍

Drain Repair vs. Drain Cleaning — What's the Difference?

‍

Drain cleaning clears buildup — grease, hair, food, mineral deposits, and other stuff that accumulates inside a pipe over time. It's the right call when the pipe is fine but water isn't flowing through it. Most household clogs are cleaning problems.

Drain repair fixes the pipe itself — cracks, collapses, root intrusion, corrosion, or damaged sections. It's the right call when cleaning doesn't hold, when the problem keeps coming back to the same spot, or when a camera inspection shows physical damage.

We start every diagnosis with a look inside the pipe so you're not paying for a repair when a cleaning would do — or getting a temporary fix when the pipe actually needs work.

Not sure which you need? Give us a call, or see our drain cleaning services page for the cleaning side.

‍

Drain Repair vs. Sewer Line Repair — Which One Applies?

‍

Drain repair covers the pipes inside your home and the short runs under the foundation before they connect to the main sewer line. Kitchen drains, bathroom drains, laundry lines, floor drains, and the branch lines that connect them all — that's drain repair territory.

Sewer line repair covers the main line running from your house out to the city sewer connection or your septic tank. It's underground, exterior, and involves different tools and access methods.

If the problem is affecting one or two fixtures inside the house, that's usually drain repair. If multiple drains are backing up at once, or if you're seeing yard issues over the sewer line, it's more likely a sewer line problem.

‍

What to Do While You Wait for a Plumber

‍

If you suspect drain damage rather than just a clog, a few things can help before we arrive:

‍

• Stop using the affected fixtures if possible to keep water out of the damaged line
• Avoid using chemical drain cleaners — they can damage cast iron pipes further and won't solve a physical break
• Clear the area around any suspected leak or wet spot
• If you see water damage on the ceiling or walls, snap photos for insurance
• Note the exact symptoms (which drains, how often, any smells or sounds) — helps us diagnose faster
• If sewage is backing up into the house, turn off water at the main and call us right away
• ‍

Frequently Asked Questions

‍

Q: How do I know if I need drain repair or just drain cleaning?

‍

‍A: If a drain clears with cleaning and stays clear, it was probably just a clog. If it keeps clogging in the same spot, if cleaning only helps for a few days, or if you're seeing sewage smells or wet spots near the pipe, you're likely dealing with a damaged pipe. A camera inspection tells you for sure.

‍

Q: What causes drain pipes to break or crack?

‍

‍A: The most common causes in Lowcountry homes are age (cast iron drain lines corrode over decades), tree roots (they find their way in through small cracks), ground movement (sandy soil shifts), foundation settlement, and physical damage from renovation or landscaping projects.

‍

Q: How much does drain repair cost in Summerville, SC?

‍

‍A: It depends heavily on where the damage is and how much of the line needs to be repaired. A spot repair to a section under a sink is much less than a repair under a slab. A full drain line replacement is a bigger job. We give upfront pricing after the camera inspection so you know what you're looking at.

‍

Q: Do you have to break up my slab to fix a drain under it?

‍

‍A: Sometimes yes, sometimes no. In some cases we can access the damaged pipe from a wall or crawl space instead. If we do have to open the slab, we cut only what we need and try to minimize the mess. We'll show you the options and pricing before starting.

‍

Q: What is a drain pipe camera inspection?

‍

‍A: A small waterproof camera fed through the drain line lets us see exactly what's happening inside the pipe — cracks, roots, collapses, buildup, or displaced joints. It removes the guesswork and lets us give you accurate information about what needs to be done.

‍

Q: Can you fix root intrusion in a drain line?

‍

‍A: Yes. Depending on the extent, we can either clear the roots and repair the damaged pipe section, or replace the affected section entirely. If the same area keeps getting new root intrusion, replacement is usually the smarter call because roots will keep coming back.

‍

Q: Are cast iron drain lines still worth repairing?

‍

‍A: It depends on how bad the corrosion is. If it's isolated to one section, spot repair or replacement of that section makes sense. If the whole run is corroded and multiple areas are failing, replacing the whole line with PVC is usually the more cost-effective long-term move.

‍

Q: What's the difference between drain repair and pipe repair?

‍

‍A: Drain repair specifically covers waste-side plumbing — the pipes that carry water away from fixtures. Plumbing pipe repair covers the supply-side pipes — the ones that bring fresh water to your fixtures. Different systems, different pipes, different repairs.

‍

Q: How long does drain repair take?

‍

‍A: A spot repair in an accessible area (under a sink, in a crawl space) can be done in a few hours. Repairs behind walls, in ceilings, or under a slab take longer because of the access work. Full drain line replacements can take a day or more depending on the length and complexity.

‍

Q: Can I prevent drain damage?

‍

‍A: Some causes (age, ground movement, root intrusion) aren't fully preventable. But regular drain cleaning helps by reducing internal buildup that stresses the pipe. And avoiding chemical drain cleaners, especially in cast iron systems, extends pipe life. A camera inspection every few years catches problems before they become emergencies.
