FAQs
What usually causes foul sewer odors to come from my drains or yard in Lookout Mountain?
In most cases the smell indicates a blockage, break, or improper venting in your home’s main sewer line. Older clay or cast-iron pipes common on the mountain can develop cracks that let sewer gases escape. Tree-root intrusion, heavy rain runoff washing debris into the line, or a dry P-trap can also push odors back into the house.
How can I tell whether the problem is in my plumbing vents or the main sewer line?
If only one fixture smells, the issue is often a dry or faulty P-trap or vent for that fixture. When multiple drains smell or you notice sewage odor outside near your clean-out, the main line is the likely culprit. A camera inspection lets us see inside the pipe and confirm whether the line is blocked, broken, or improperly sloped.
Is sewer gas dangerous to my family or pets?
Yes. Hydrogen sulfide, methane, and ammonia in sewer gas can cause headaches, dizziness, nausea, and eye or throat irritation. In high concentrations they are flammable and displace oxygen. While most household odors are not life-threatening, it’s important to locate and correct the source quickly to protect indoor air quality.
What does a main line odor inspection cost in Lookout Mountain?
Our standard diagnostic package—which includes smoke testing, video camera inspection up to 100 ft, and a written repair estimate—starts at $189 for homes on the mountain. Pricing may vary if your line requires excavation permits or if additional footage or locator tracing is needed. We always provide upfront quotes before beginning repairs.
How long will it take to eliminate the smell once repairs start?
Minor blockages cleared with hydro-jetting or snaking can remove odors the same day. If we must repair or replace damaged pipe segments, work typically takes one to two days, followed by a short testing period to ensure the line is gas-tight. Most customers notice the odor gone as soon as airflow is restored and the line is sealed.
Can I prevent foul odors from returning after the main line is fixed?
Absolutely. Schedule a professional main-line cleaning every 18–24 months, avoid flushing wipes or grease, and keep landscaping roots away from the pipe corridor. Pour a cup of water into rarely used drains monthly to keep traps from drying out, and have us check vent stacks after major storms or roof work to ensure they stay open.
