Condensation stains on the ceiling

This is actually a very common problem, but you should not ignore it. Address it as soon as possible to prevent serious damage. You may see black spots on the ceiling if you don’t fix this issue. Condensation stains on the ceiling are mold build-up that occurs due to moisture and it can spread across the ceiling. The cold wall can result in a very similar problem. You can fix it and prevent it in the future.  

The main cause of ceiling moisture:

It usually occurs due to poorly insulated and ventilated space above the ceiling. Heat gets trapped above the ceiling and it frequently warms the ceiling. So, when you turn on the AC or natural cool air rises up and comes in contact with the heated ceiling, then this problem occurs.

This problem mainly occurs in the rainy season and the winter season. You heat the interior and that heat gets trapped. Natural cool air contacts that heat and causes condensation. You have to maintain proper ventilation in the attic to prevent it.

How to fix this problem?

You have to apply a three-step solution to prevent wet ceiling.

  • Install a rigid vent:
Sunlight increases the temperature in the attic. This increased temperature also affects the ceiling material. It can cause wet stains if humidity levels increase in the living area. So, you have to move that hot air out of the attic. Install a rigid vent on the roof. It will move hot air out and keep the attic area cool. This vent will not only reduce the ceiling temperature, but also decrease humidity levels in your house.
  • Insulate the attic:
You can easily reduce the effect of hot air on the ceiling by installing adequate insulation. It will also recue your power bills by preventing heat from escaping out through the ceiling. Install insulation blanket and seal it perfectly. This affordable solution will help you in saving a lot of money!
  • Reduce humidity levels in your home:
Install new vents, open windows more often, and keep the doors open longer to remove excess heat. Humidity levels can also increase due to poorly ventilated bathrooms. So, install new exhaust fans to remove hot and humid air out of the house. Thus, you can prevent ceiling condensation stains and mold build-up on the ceiling.
