3 Unpleasant Things You May Find if your Home is Too Humid

Here in Houston, we’re no strangers to heat and humidity. And while you may feel the humidity more easily outside, do you know how to tell if you have excess humidity inside your home? Keep the telltale signs below on your radar.

What Can I Find in My Home if it's Humid?


Mold thrives in a damp, humid environment. Any increase in humidity in your home’s environment and it becomes a breeding ground for mold to form.

If you notice mold growth, look in areas that collect moisture — like leaks under your sinks, leftover water in pots and pans, or moisture pooling in your grout.

Ceiling or Wall Stains

After a hot shower or bath, do you ever see your ceiling sweating? This is because the hot air creates condensation, leaving moisture on your ceiling. You can also find stains due to leaks from your roof or water lines and drain wastes that have become separated or cracked.


Do you notice any odd smells? With the growth of mold and mildew, comes some musty, funky odors. If you don’t notice it right away, spend some time outside in fresh air. When you come back into your home, you’ll be more likely to detect odd odors better.

Why is my House so Humid?

You can't just pinpoint one thing that makes your house humid. In fact, there are many culprits that affect the humidity levels within your residence. Some of these factors include:

  • Insulation

  • Construction

  • Climate

While located in Texas, your home can be humid just due to the outdoor temperature — and while outside the humidity can be as high as 90%, inside the humidity levels are supposed to be between 30-50%. Here are some other factors that contribute to increased humidity in your home:

Oversized Air Conditioner

Regardless of if it's your central air conditioning unit or one for your window, if your unit is oversized, you're going to run into humidity issues. Your AC unit acts as a dehumidifier as the evaporator coils grab moisture from the air. But, if your unit is too large, then it's going to run shorter cycles, not allowing the evaporator coils to do their job.

Basically, if you notice that your house is too humid, pay attention to how often your air conditioner is turning on and off. If it's too frequent, call a professional to access your AC.

Daily Activities

This may sound silly, but some of your daily activities make a contribution to the humidity levels in your house. Cooking, taking a hot shower, and using appliances like your dishwasher and washing machine, all play a part.

In order to reduce humidity, you must make sure there is proper ventilation within your bathroom, kitchen, and laundry room. Keep exhaust fans on when cooking or open big windows when possible. Another tip is to make sure your appliances are working efficiently — clean out the dryers vent and make sure there is no backed up grease in your oven or stove.
