Sewage Smell in the House: What It May Mean
A sewage smell in the house is unpleasant, and it usually means something in the drainage is not working as it should. The smell alone cannot diagnose the cause, but it is worth taking seriously, especially if it appears with slow drains or water where it should not be. If there is any sign of a backup, arrange sewage cleanup and avoid contact with the water.

This guide explains what a sewage smell may point to in general terms. No diagnosis is offered from a smell alone.
What a sewage smell may point to
In general terms, a sewage smell may point to a dried-out trap in a little-used drain, a blocked or damaged vent, or a partial blockage further along the pipes. It can also be an early sign of a backup.
The smell may come and go, or it may be strongest in one room, often a basement or a bathroom. Where it is strongest can be a useful clue for the professional who investigates.
Signs that point to something more serious
A smell that appears with gurgling drains, water backing up into a bath or shower, or damp patches near a drain is more serious than a smell on its own. Those signs suggest water is not draining as it should.
If you see sewage or contaminated water, do not try to clean it up yourself. Avoid contact and call a professional.
What to do when you notice the smell
Note where the smell is strongest and whether drains are slow or gurgling, and avoid using fixtures that drain into the affected pipes until someone has looked at it. Do not pour chemicals down the drain as a first response.
A professional can check the drainage and, where a backup has happened, emergency water removal may be needed before any other work can start.
Getting the cause found
Finding the cause usually means looking at traps, vents and the state of the drains, which is work for a professional. Guessing at the cause from the smell alone is not reliable.
Homeowners in New Rochelle face the same range of possible causes as anyone else, and the same advice applies: take the smell seriously, and get it checked.
