Q: The paint in our hall bath always peels. Was the ceiling not properly primed? Now we are getting mildew in the bathroom on the ceiling and walls. What should we do?
A: This is a pet home repair project of mine. Paint peels for only a couple of reasons.The primary reason is moisture. The steam from the shower rises and stays on the ceiling. It is critical that the exhaust fan be in use with every shower.
I recommend connecting the fan to the light.That way the fan goes on every time the light goes on. Also check the fan that it is clean and effective in removing the steam.The mildew is created by moisture in a dark environment. Use bleach to remove the mildew from tile. You may have to replace the sheet rock in the ceiling and walls.

    Great tips, and people should check if their bathroom fans vent outside the house or just into their crawlspace / attic. A lot of people I know discovered that the fan put moisture into the attic and onto nearby insulation.

    Great tip Ethan. Moisture on the insulation could create more mold and mildew, the exact thing we want to prevent. It can also cause wood rot. If the fan DOES NOT vent out side the house, what would be some of the solutions? Attic/gable fan? De-humidifier?

    My daughter lives on the bottom floor of a 2-story condo--apts. turned into condos. Her bathroom doesn't have a vent fan and where would it be vented to? She's got a mildew problem. Any suggestions?

    When we were hit with the tornado that landed less than three miles from my house, I noticed the high windes was causing a little water to come in via the vent. Now, I have notices a slight water stairn on my bedroom ceiling as an after affect. I have never gone into the attic to investigate, but after reading this, I most certainly will. Pray I don't find mold, b/c then it really may be time to hire a bull dozer.

  • Lisa, if she does not have a fan, she has a window. That should be opened just a crack on the top to allow the moisture to escape. When sidewall venting fans it is not suggested as we used to do to vent out from the soffit area. This creates a pressure in the duct preventing it from properly working on a breezy day. Ethan is correct also. Be sure to vent system out of attic. Insulate pipe with at least R-6 and pitch it one way or the other. Ideally outwards, but in most cases it ends up being pitched in towards the fan. Regardless of what way its pitched. Just do not allow it to go up and down where moisture can collect in the pipe should it condense in colder weather.
