Many homeowners spend a considerable amount of money on property maintenance and repairs every year. At a glance, it may not seem like much, but in the long run, a small 6-figure mortgage may require thousands for repairs in a year.

Due to changing temperature and humidity, weather-related repairs are one of the more common home maintenance concerns among homeowners. You need to ensure that your house can withstand heavy rains, extremely hot temperatures in the summer, and even potential flooding, among others.

We know these conditions can greatly affect our houses, but we often forget another factor that can slowly damage our homes permanently — unregulated humidity.

Troubles of high humidity in your homes

Humidity is all about air and air is everywhere. When unregulated, it can be an uncomfortable and unavoidable part of life depending on where you live. Many people view humidity as a minor discomfort, and only few are aware of the long-term problems it can cause for homeowners and families. High humidity areas can give rise to mold growth. Molds thrive in moist and warm environments and homes with a high humidity makes it the ideal environment for most kinds of mold. These  molds thrive with moisture, exposure to light, and close environment to reproduce in. Having mold in your house reduces indoor air quality and may cause potential health issues, especially for people with allergies and asthma. Some molds can be even dangerous even for those without existing respiratory problems, and in rare cases could even be toxic. High humidity can also cause water damage. Wood, ceramic tiles, and other home materials can become warped and damaged in some severe cases.

Signs of high humidity

To avoid these potential problems, you would need proper ventilation in areas where moisture would build up. Having a reliable indoor humidity monitor (indoor hygrometer thermometer humidity monitor) can help you regulate moisture. Here are some of the major signs of high humidity.

  • Check to see if you have condensation forming on your windows throughout the day. Constant condensation is highly unusual and it is even more alarming if the condensation happens so often.
  • Stale or musty smell on your furniture and clothing can be a sign that home humidity is too high and it could also mean that ample mold spores are growing in your house.
  • Check out your warping wood or floors, since it could be mistaken as a byproduct of water or flood damage and not gradual degradation because of humidity exposure.
