Summer Isn’t the Only Thing Heating Up

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.

Why Do Drains Smell Worse in Summer?

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.
