How do I dry out my damp house?

Get a dehumidifier one big enough for the square footage of your house

Where do you believe the dampness coming from? Is it from bathing or drying clothes inside? Perhaps you have a clogged AC line or leaky pipe.

Exhaust fans and a dehumidifier (you might need more than one) will give you the quickest relief, but you'll really want to address the source. See if you don't find this informative: https://www.energywise.govt.nz/at-home/dampness/

You'll want to treat the mildew with a bleach solution.

You need to purchase a dehumidifier. Look for one on craigslisist before buying new. This will take care of your problem.

Ok. Thanks.

Look for a sufficiently large dehumidifier with good reviews (consumer reports or similar) because these should be set to no higher than 40 % humidity and if your house is very damp, it may need to run 12-16 hours a day.

Have you checked your yard for drainage sloping toward your house? If so, re-route it. Downspouts should discharge water at least 10' away from your foundation.

You may need a French drain system involved, or at least modification of soil around your house's foundation if you have heavy clay.

I wonder if your house has a moisture barrier atop your concrete?

Lots of questions first. Where do you live climate wise? Down South, out East? Near the water? It will make a difference. Sounds like you are on slab? Water lines could be run in the floor possibly. You could have ground water seepage also. Concrete and block are very pourous and will transfer water to the block interior. They wick it in. I would Drylock all the interior block walls. I would follow the advice of the above poster. You need to make sure that soil is sloped away from the home. Make sure you have gutters on your roof line. If you have clay soil it will not drain maybe that is contributing to your problem if you have clay soil. Good Luck.

Vinegar will clean the mildew on the walls, but you really need a home inspection and a whole house dehumidifier. If you are in a humid location, seaside, deep South, etc. You can't live without dehumidifier. My girlfriend has a separate one just for her closet and even in winter, the amount of water that comes out of there is astounding.

I have two dehumidifiers. One in the basement and one in the living space. (Ranch) I had mold issues the first year but not now.
