Avoid the Summer Stink: What That Sewer Smell Means and When to Call the Pros

June 11, 2025

It’s a beautiful June day—windows shut, the AC is cranked, and you’re ready to relax. But then you catch a whiff of something foul coming from the drain.

It’s not your imagination. Summer is prime time for sewer odor problems, and there’s a good reason why. Heat, humidity, and even your air conditioning system can all make things worse.

Whether it’s your bathroom, basement, or kitchen, any foul odor from a drain is your home’s way of saying something’s off. And if you're a business owner, even a hint of odor can send customers running.

There are several reasons sewer gas odors are more obvious when the weather gets hot:

• Heat intensifies odors: Warm temps speed up decomposition of organic materials in your pipes. That sour smell? It gets stronger—and travels faster.
• Dry drains: Drains that go unused for long periods may lose their water seal (in the trap), allowing sewer gases to rise into your home.
• Buildup and bacteria: Grease, food scraps, and soap scum cling to pipe walls. In warm conditions, bacteria multiply, and so does the smell.
• Ventilation issues: Summer air pressure and poor venting may force odors back inside instead of allowing gases to exit outdoors.

Not sure whether the smell is serious? Here are signs it’s time to contact the experts:

• Odors persist even after cleaning
• Smells come from multiple drains
• Gurgling sounds or slow drainage
• Smell worsens when the AC is running or windows are closed
