Sewer Odor Removal
Find the Source, End the Smell
Persistent sewer smell in a bathroom, basement or whole building? Our plumbers track down where sewer gas is escaping, from dry traps to cracked vents, and fix the actual source.
Sewer Odor Removal Starts With Finding Where Gas Gets In
Your plumbing is designed to keep sewer gas out. Every fixture has a trap, a curved section of pipe that holds water and blocks gas from rising out of the drain. Vent pipes carry gases up through the roof, where they disperse harmlessly. When either part of that system fails, sewer gas can enter living spaces. Air fresheners and drain cleaners only mask the problem, because the gas keeps coming until the opening is sealed.
Common sources are often simple. Traps in guest bathrooms, basement floor drains and unused showers dry out through evaporation. Toilet wax rings fail, letting gas escape at the base. Other causes take more investigation: a vent pipe cracked or disconnected inside a wall or attic, a failed air admittance valve, a missing cleanout cap or a broken drain beneath the slab. Our plumbers check each possibility systematically until the source is confirmed.

How Smoke Testing Reveals Hidden Sewer Gas Leaks
When the source isn’t obvious, smoke testing is one of the most effective tools available. A machine blows harmless, non-toxic smoke into the drain system, usually through a cleanout or roof vent, while vents are temporarily sealed. The smoke follows the same paths as sewer gas. Wherever it escapes, through a cracked pipe, a loose joint, a dry trap or an unsealed opening, it becomes visible, revealing the exact location of the leak.
Smoke testing is particularly useful in larger homes and commercial buildings with long vent runs, after remodels where pipes may have been disturbed, and when odors come and go with wind or weather. It can also show whether odors are entering from outside, such as through a broken lateral near the foundation. Before testing, we let occupants and neighbors know, so visible smoke at the roof vent doesn’t cause concern.

Benefits of Professional Sewer Odor Removal
Fixing the source ends sewer odors permanently instead of masking them. It protects indoor air quality, since sewer gas can contain hydrogen sulfide, ammonia and methane that cause headaches and irritation. Repairing vents restores proper drainage and stops gurgling. Sealing cracked drains keeps wastewater out of walls and soil. And for businesses, eliminating odors protects the customer experience, keeps employees comfortable and supports a clean result during routine health inspections.

Our plumbers eliminate sewer odors in homes, vacation rentals, restaurants and commercial buildings across California, Texas and Florida, where heat and humidity often make even small sewer gas leaks more noticeable.
Is It Sewer Gas or Something Else?
Not every bad smell is sewer gas. Identifying the odor helps you respond correctly, and one possibility requires immediate action for safety.
Natural gas companies add a sulfur or rotten egg odor to gas so leaks can be detected. If you smell that odor near gas appliances or lines, get everyone out of the building right away, avoid using switches or flames and phone the gas company or 911 once you are safely outside.
A rotten egg smell only from hot water taps often comes from a reaction in the water heater, not the sewer. Musty odors usually point to mold or moisture. Sewer gas typically smells like sewage near drains, toilets or floor drains, and our plumbers can help confirm which situation you’re facing.
How Our Sewer Odor Removal Works
Tell us where and when the smell appears, such as after showers, during windy weather or only in certain rooms.
Your plumber checks all fixtures for dry or damaged traps, inspects toilet seals, cleanout caps and air admittance valves and looks for visible drain or vent damage. If the source remains unclear, we perform a smoke test or camera inspection to locate hidden leaks in drains and vent pipes.
Once the source is confirmed, we explain the fix and the cost, then complete the repair, whether that’s resealing a toilet, replacing a valve or repairing a cracked vent or drain. We verify the odor is resolved and share tips, like running water in unused drains regularly to keep traps full.

Sewer Odor Removal Questions Answered
Why does my bathroom smell like sewage?
Common causes include a dry trap, a failed toilet wax ring, a cracked vent pipe or a loose drain connection behind the wall.
Is sewer gas dangerous to breathe?
At low levels it causes headaches and irritation. Higher concentrations can be harmful, so persistent sewer odors should be investigated promptly.
Why does an unused drain smell?
The water in its trap has evaporated. Running water for a minute refills the trap and blocks sewer gas from escaping.
Is smoke testing safe for my home?
Yes. The smoke used is non-toxic and leaves no residue. It simply makes hidden leaks visible so they can be located and repaired.
Why does the smell get worse in wind?
Wind can create pressure changes in vent pipes, pulling water from traps or pushing gas through cracks. A vent inspection usually finds the cause.
