If you're wondering, "Why does my house smell like sewer?", here's what every homeowner should know.

A sewer smell usually means sewer gases are escaping somewhere inside your home. Besides being unpleasant, persistent sewer odors often indicate a plumbing problem that should be inspected by a licensed plumber.

Ignoring sewer smells could eventually lead to:

The sooner the issue is diagnosed, the easier and less expensive it often is to fix.

Several plumbing issues can allow sewer gases to enter your home. Here are the most common culprits our Athens plumbers find.

Every sink, shower, bathtub, and floor drain has a P-trap that holds water to prevent sewer gases from entering your home.

Solution: Run water for about 30 seconds to refill the trap.

A cracked or collapsed sewer pipe is one of the most serious causes of sewer odors. Common warning signs include:

A damaged wax ring beneath your toilet can allow sewer gases to leak around the base. Signs include:

Replacing the seal early prevents additional damage.

Grease, wipes, roots, and years of buildup can partially block your sewer line. As pressure builds inside the pipe, sewer gases may escape into your home.

Professional drain cleaning or hydro jetting often restores proper flow.

If the odor is strongest outside your home, possible causes include:
