Service Details

If your home smells like sewer gas, there is usually a plumbing problem behind it. That odor is not just unpleasant. It can point to a dry drain trap, a broken vent, a loose toilet seal, a clogged drain line, or even a damaged sewer pipe. At Plunger Pros, we help homeowners in New Braunfels, San Antonio, and surrounding areas find the real cause and fix it the right way. That is what we mean by Plumbing Done The Proper Way.

We are a licensed and insured plumbing company, and we bring a personal, professional approach to every call. When you call us for a sewer smell in the house, we do not guess. We inspect the plumbing system carefully, explain what we find in plain language, and recommend the best repair based on the condition of your drains, fixtures, venting, and sewer line.

What Causes a Sewer Smell in a House?

Sewer odors can come from several places. In many homes, the smell starts when sewer gas escapes through a part of the plumbing system that is not sealed the way it should be. Common causes include:

  • Dry P-traps: Floor drains, guest bathroom sinks, showers, tubs, or laundry drains that do not get used often can dry out. When the water in the trap evaporates, sewer gas can come back into the home.
  • Broken or blocked plumbing vents: Your plumbing vent system helps sewer gases move safely out through the roof. If a vent pipe is clogged, cracked, or installed wrong, odors can build up indoors.
  • Worn toilet wax rings: A toilet should seal tightly to the drain. If the wax ring fails, sewer gases and even small leaks can escape around the base.
  • Drain line clogs: A partial blockage in a sink drain, shower drain, or main sewer line can trap waste and create strong odors.
  • Sewer line damage: Cracks, separations, root intrusion, or pipe corrosion in the sewer line can allow smells to enter the home or yard.
  • Loose fittings or damaged pipes: In some cases, a bad connection under a sink, behind a wall, or in a crawl space can release foul odors.
  • Bacteria buildup: Biofilm, waste buildup, and organic matter in drains can create a smell that seems like sewer gas, especially in kitchen and bathroom drains.

Because there are several possible causes, a proper diagnosis matters. Treating the smell without finding the source often leads to the odor coming right back.

Our Sewer Odor Inspection Process

When we inspect a sewer smell issue, we start by listening. We ask where the odor is strongest, when you notice it most, and whether you have seen slow drains, gurgling sounds, bubbling toilets, or water leaks. Those signs help us narrow down the source faster.

From there, our service may include:

  • Checking sinks, tubs, showers, toilets, floor drains, and laundry drains
  • Inspecting traps, seals, drain connections, and exposed piping
  • Testing for signs of venting issues
  • Looking for drain blockages and poor flow
  • Inspecting the toilet base for a failed wax ring
  • Evaluating the condition of the main sewer line if needed
  • Recommending camera inspection when we suspect hidden sewer line trouble

Our goal is to find the source of the smell, not just mask it. Once we know what is wrong, we explain the repair options clearly so you can make the best decision for your home.

Repairs We May Recommend

The right fix depends on what is causing the odor. We provide targeted plumbing repairs to stop sewer smells and restore safe, clean function. That may include:

  • Refilling and maintaining dry traps
  • Cleaning and clearing clogged drains
  • Replacing a failed toilet wax ring
  • Repairing or replacing damaged drain piping
  • Addressing vent pipe problems
  • Helping diagnose sewer line cracks, offsets, or root intrusion
  • Repairing fixture connections and drain seals

Some sewer smell problems are simple. Others are signs of a deeper drain or sewer issue. Either way, we take the time to do the work carefully and professionally. At Plunger Pros, we believe in lasting repairs, honest communication, and Plumbing Done The Proper Way.

Signs You Should Call a Plumber

If you notice any of the following, it is a good idea to have your plumbing checked:

  • A rotten egg or sewage smell in bathrooms, kitchens, laundry rooms, or near drains
  • Odors that get worse after using water
  • Gurgling sounds from drains or toilets
  • Frequent drain clogs or slow drainage
  • Water around the base of a toilet
  • Bad smells coming from a shower, tub, sink, or floor drain
  • Sewer odor inside the house or outside near the foundation

Sewer gas odors should not be ignored. Besides the smell, they can signal plumbing leaks or hidden pipe problems that may get more expensive over time.

FAQs

Sewer Smell in House FAQs

If there’s a bad sewer odor in your home, it’s not something to ignore. At Plunger Pros, we help homeowners in New Braunfels, San Antonio, and surrounding areas find the source fast and fix it the right way. Here are the questions we hear most often.

  • Why does my house smell like sewer gas?

    A sewer smell in your house usually means sewer gas is escaping somewhere it should not. Common causes include a dry P-trap, a broken toilet wax ring, a clogged or damaged vent pipe, a drain issue, or even a cracked sewer line. We track down the real source instead of guessing, then make the needed repair. That’s how we deliver Plumbing Done The Proper Way.

  • Is sewer gas in the house dangerous?

    It can be. Even when the smell seems mild, sewer gas is a sign that something is wrong with your plumbing system. The odor can cause headaches, nausea, or discomfort, and it may point to a bigger drain or sewer problem. If you notice a strong or ongoing smell, give us a call so we can inspect it and make sure your home is safe.

  • Can a sewer smell go away on its own?

    Sometimes a simple issue like a dry drain trap can improve after water is run, but many sewer odor problems come back because the root cause was never fixed. If the smell keeps returning, it is time for a professional inspection. We can identify whether it is a fixture issue, venting problem, drain blockage, or sewer line concern and take care of it before it gets worse.

  • Do I need a plumber if I only smell sewer odor in one room?

    Yes, it is a good idea. A sewer smell in one bathroom, laundry room, kitchen, or utility area often points to a local plumbing issue such as a floor drain, sink drain, toilet seal, or vent connection. The good news is that isolating the smell to one area can help us diagnose it faster. We’ll inspect the affected fixtures and explain your options clearly before any work begins.

  • How do you find the source of a sewer smell?

    We start with a hands-on plumbing inspection and check the most likely problem areas, including drains, toilets, vent stacks, cleanouts, and exposed plumbing connections. In some cases, we may recommend drain or sewer line testing if the source is hidden. Our goal is to find the actual cause, not just cover up the odor. As a licensed and insured plumbing company, Plunger Pros focuses on lasting repairs you can trust.

  • Why should I call Plunger Pros for sewer smell problems?

    We’re a local plumbing company serving New Braunfels, San Antonio, and surrounding areas with professional service and a personal touch. We are licensed (M45279) and insured, and we take the time to explain the problem in plain language so you can make the right decision for your home.
