Sewage Smell in the House? Here's What It Means

That unmistakable rotten-egg, sewage odor inside your home isn't just unpleasant — it can signal a real problem with your drains or sewer line, and sewer gas isn't something to ignore.

Common Causes

• A dried-out drain trap (common in guest baths and floor drains) letting gas up
• A cracked or loose toilet wax ring
• A broken or blocked plumbing vent
• A cracked drain or sewer line under the home
• A failing sewage ejector seal in the basement

The Easy Fix First

If the smell is near a rarely used sink, tub, or floor drain, the trap may have simply dried out. Run water for a minute to refill it. If the odor persists or comes from multiple spots, the cause is deeper.

When to Call Us

Persistent sewer gas, especially with slow drains or gurgling, points to a vent or line problem. We'll locate the source — and if it's a cracked line, a camera inspection shows exactly where.
