Professional Sewage & Drain Odor Removal Services

From a lingering sewer gas smell to odors left behind after a backup or flood, our sewage and drain odor removal services eliminate odors at the source, not just mask them. We treat walls, floors, carpets, and HVAC systems to restore fresh, healthy air to your home or business once the plumbing issue is fixed.

Sewage Odor Removal

After a backup or leak, sewage odor soaks into flooring, drywall, and porous materials. Our sewage odor removal service deodorizes the affected space and surrounding air so the smell is gone, not covered up.
Drain odors rise from sinks, tubs, and floor drains and spread into nearby rooms and ductwork. We deodorize the surrounding air and surfaces so the smell stops circulating through your home.

Drain Odor Removal

Sewer gas smells like rotten eggs and can linger in walls, carpet, and HVAC systems long after the source is repaired. We neutralize the lingering odor throughout the space. Plumbing repair should be handled by a licensed plumber.

Sewer Gas Odor Removal

Septic Odor Removal

Septic odors can drift indoors and cling to fabrics, flooring, and air ducts. Our certified technicians use professional deodorization and ozone treatment to remove the smell from the affected areas once the septic issue has been addressed.

Wastewater Odor Removal

Wastewater from leaks, overflows, and failed lines leaves a heavy, stale smell in floors and walls. We treat affected materials and air to eliminate wastewater odor so the space is comfortable to live and work in again.

Flood-Related Odor Removal

Floodwater leaves a damp, sour smell that sinks into carpet, drywall, and insulation. Once the water damage has been properly cleaned up and dried, we remove the lingering flood odor from the structure and air.

Why Sewage Smell Keeps Coming Back in Dallas Homes

Sewage odor doesn’t just float in the air. Moisture and organic residue settle into drywall, flooring, subfloors, insulation and ductwork, then slowly release odor for months or even years.

Sound familiar?


It’s worse on hot, humid days. Texas heat and humidity pull trapped odor out of floors and walls.

  • It returns when the AC turns on. Your HVAC system pushes sewage odor from the ducts into every room.

  • The plumbing repair didn’t fix it. Fixing the line stops the source, but the odor already absorbed into materials stays behind until it’s treated.

  • Air fresheners only cover it. Sprays, candles and plug-ins mask the smell for a few hours, but the source is still there.


Real sewage odor removal means treating the odor left in your home, not covering it up. That’s exactly what we do. If the plumbing source is still active, fix it first.

How It Works

01 - INSPECTION & ASSESSMENT

On-site sewage odor inspection with a detailed report and an itemized removal estimate for complete pricing transparency

03 - THERMAL FOGGING

Thermal fogging vaporizes deodorizers to travel like smoke, eliminating stubborn odors trapped deep in walls and floors.

02 - OZONE TREATMENT

Industrial-grade ozone generators break down sewage odor molecules in air, walls, carpets and HVAC, often in one session.

04 - ULV FOGGING

ULV fogging disperses a fine deodorizing mist that reaches corners, crevices and hard-to-reach areas other methods miss

What DFW People

Say About Us

We had a really bad cigarette smell in the house and nothing we tried worked. We cleaned, opened windows, used sprays, but the smell was still there. MyPureZone came out to our home in Plano, TX and did the treatment. After that the house smelled much better and the cigarette odor was basically gone. Very happy with the result. I would use them again.
    Alex Y - Plano, TX

    Danny Estes - DFW Area
and easy to work with from start to finish. Most importantly, they removed a cannabis odor from my rental property that I honestly thought would never go away. They came back for a second treatment to make sure it was completely gone, and it is. If you have an odor problem you think is hopeless, these are the people to call.

FAQs

Is sewer smell in the house dangerous?

Sewer gas contains hydrogen sulfide and methane. At low levels it usually causes headaches, nausea or irritation, but high concentrations are dangerous and methane is flammable. Do not ignore a strong or growing sewer smell. Ventilate the area, leave if it is strong, and have a licensed plumber find the source right away.

What causes sewer smell in the house?

The most common causes are a dried-out drain trap in a rarely used sink, tub or floor drain, a failed wax ring under a toilet, a blocked plumbing vent on the roof, or a cracked drain pipe. A licensed plumber should fix the source. After the repair, odor that has soaked into flooring, walls or HVAC can be neutralized.

Why does the sewer smell in my house come and go?

An on-and-off sewer smell is often tied to wind, rain or air pressure changes that push sewer gas back through roof vents, or to a drain trap that gets siphoned dry when the washer or toilet drains. Because it is not constant, it is easy to miss. Note when it happens and tell your plumber, since that helps pinpoint the cause.

Will sewage smell go away after a backup?

Helvetica Light is an easy-to-read font, with tall and narrow letters, that works well on almost every site.

What causes sewer smell in a house with a septic tank?

With a septic system, indoor sewer smell usually comes from a full tank that needs pumping, a blocked vent pipe, a dry drain trap or a problem with the drain field. A brief smell right after pumping can be normal. If it lasts, have a septic professional inspect the system first, then the indoor odor can be treated.
