My parent’s basement bathroom is being taken over by mold. The vent isn’t working and I’m not sure how to clean it without spreading the mold. Is this a scenario where I should call for professional help? Also, if that’s the case, who do I call?

    White cleaning vinegar will kill the spores. Once that's done, you can work on getting rid of the stains left behind. Consider adding a small ceiling fan to circulate the air.

  • Hi, Faith!

    For a long term solution, the fan definitely needs to be replaced! Buy a fan that pulls greater CFMs (cubic feet per minute) than the existing fan. It's an easy DIY project - just make sure the power supply is turned off first! Here is a how-to video from Home Depot... I hope this helps!

    Call a BUilder if the vent is in the brickwork. If it is an electric vent - Call in an electrician to fit a new one. If you own the property maybe you would like to consider a better form of consendsation extraction? For the mold there are ssprays for black mold at the supermarket in the cleaning Isle.

    Without proper ventilation, moisture just sits there, which creates a perfect environment for mold to thrive. The first thing you want to do is try to remove as much moisture as possible. Using a dehumidifier can help with that. Cleaning the mold with a mixture of water and vinegar or a mold remover works, but make sure to wear protective gear like gloves and a mask. If the mold keeps coming back or it's spread to a large area, you might want to consider calling in professionals. They can not only handle the mold but might also suggest fixing the ventilation issue. You could even look into companies that specialize in related services like indianapolis junk removal; they often handle situations involving mold removal and cleanup too.

    Who owns the property? Sspeak to them about the damp! If your parents are the owners, call in a Building Surveyor to do a Survey and give their proffesional opinion at what is causing it and what to do about it!

    Hi Faith, hope this helps you. Most of the fans in bathrooms are "plug and play" meaning you can remove the 1 screws that hold it in and take it to your nearest home store and get a new one. Once you install it, you can work on cleaning up the mold. Here is a great recipe

    Combine two tablespoons of borax with 1/4 cup white vinegar and 2 cups of hot water in a plastic bucket or bowl. Fill a spray bottle with it. Spray the solution on your painted walls. Remove the residue by scrubbing it repeatedly and wiping it clean with a damp cloth.

    Hi Faith: Yes, I'd definitely call in a professional for the cleanig. Better safe than sorry. You need air circulation in order to keep mold at bay. The vent fans aren't that expensive, maybe $20 or $30, which is cheap, considering the consequences of not having a working one and the mold building up. If you are just replacing the one you have, that should be pretty easy as the wiring is already there.
