The short answer
What Causes Sewer Gas Symptoms
Sewer gas forms when organic waste breaks down. The main culprits are hydrogen sulfide, methane, ammonia, and carbon dioxide. Hydrogen sulfide is the one that smells like rotten eggs, and it can irritate your eyes, nose, and throat. Breathing it in can also trigger headaches, dizziness, and nausea.
The severity of symptoms depends on how much gas you breathe and for how long. Short exposure to a small leak might cause mild discomfort. A bigger leak or a confined space can lead to stronger reactions. If you notice the smell, treat it as a warning to act quickly and ventilate the area.
How Sewer Gas Affects Your Body
Hydrogen sulfide interferes with how your cells use oxygen. That can make you feel lightheaded or dizzy, similar to the feeling of not getting enough air. Nausea often follows because the gas irritates your stomach and digestive tract. These symptoms are your body's way of telling you to get away from the source.
Long-term exposure, even at low levels, can be worse. It may cause fatigue, loss of appetite, or trouble concentrating. If you or anyone in your home feels dizzy, nauseous, or has trouble breathing, leave the area immediately. Open windows and doors to let fresh air in, and see a doctor if you do not feel better quickly.

Common Sources of Sewer Gas in Homes
A sewer smell in your home usually means a leak or a vent problem. A cracked pipe, a loose toilet base, or a dried-out floor drain can let gas escape. Blocked or improperly installed vent stacks can also trap gas and push it back into your living spaces. Even a small gap can let enough gas in to cause symptoms.
Check for the smell near toilets, sinks, and floor drains. Look for water stains or damp spots that might point to a hidden leak. If you use a septic system, a full or failing tank can also cause sewer gas to back up. If you cannot find the source, a local water damage pro can help locate it.
How to Stop Sewer Gas from Entering Your Home
Act quickly when you notice a sewer smell. Open windows and doors to air out the space. Do not use fans that blow air toward other rooms, as that can spread the gas. Check that all drains have water in them, since a dry drain can let gas through. Pour a cup of water down each drain regularly to keep the trap sealed.
For a persistent smell, call a plumber to inspect your pipes and vents. They can find and fix cracks, blockages, or venting issues. If the problem involves water damage from a leak, the pros can handle drying and cleanup. If you live in Layton, keep a list of trusted local pros handy for quick action.
When to Bring in Water Damage Pros
Sewer gas often comes with hidden water damage. A leak that lets gas escape may also be soaking your walls, floors, or ceiling. If you see stains, warped wood, or damp drywall, you need to deal with both the leak and the moisture. Ignoring the water can lead to mold and more damage.
Local water damage pros can inspect your home for leaks and moisture. They use tools to find hidden water and assess the extent of the damage. They can also dry out affected areas and repair materials like drywall or flooring. If you suspect a leak, do not wait, because the longer water sits, the worse the damage gets.
- Look for water stains on ceilings or walls
- Check for musty or sewage-like odors
- Feel for damp spots on floors or carpet
- Inspect pipes under sinks for drips
- Watch for warping or bubbling in drywall
