When you leave wet, smelly clothes in the hamper for too long, they can start to decompose and emit an unpleasant odor. To avoid this, ensure you sort through and wash your laundry regularly so it doesn’t pile up and create an unpleasant smell in your house.

When clothes are not dried properly before storage, moisture can accumulate and create an ideal environment for mold and mildew to grow. This will result in a musty smell that can be difficult to remove without proper cleaning.

Pet urine and feces contain bacteria and other substances that are difficult to remove, so if these aren’t thoroughly cleaned up, they will cause an unpleasant odor. If you have pets it’s important to clean up any accidents quickly and thoroughly to prevent odors from lingering in your home.

The refrigerator might be the problem

When dust, debris, and other contaminants accumulate within the system, they can create an unpleasant smell that fills your home. To help prevent this issue, regularly clean or replace the air filters in your HVAC system and any other components that may have become clogged with debris. Additionally, having your ducts professionally cleaned every few years can also help reduce musty odors in your home.

Leaky pipes

A leak can occur for many reasons, from an old pipe that needs to be replaced to a crack in a pipe that’s caused by environmental factors like freezing temperatures or an earthquake. It’s important to identify the source of the leak and repair it as soon as possible to prevent further damage and odors from developing.

Water coming in through the roof

This can happen for various reasons, from small holes or cracks in the roofing material to missing shingles or tiles that allow water to enter and spread throughout the attic space. Moisture trapped inside your attic can lead to mold growth and dampness, both of which are major contributors to unpleasant odors.

Moisture in the basement

If you notice an unpleasant musty odor coming from your basement, it could result from too much moisture. To reduce moisture levels, ensure your home has adequate air circulation and inspect any pipes or fixtures in the area for leaks. You may also want to install a dehumidifier or add a small fan to help keep moisture levels down.
