Stains on walls or floors can be caused by a variety of factors, including moisture, dirt, and spills. It is important to identify the cause of the stain in order to determine the best way to clean it. If the stain is caused by moisture, it is important to check for moisture under the house to ensure that there is no underlying problem that needs to be addressed.
There are a few different ways to check for moisture under your house. One way is to use a moisture meter. A moisture meter is a device that measures the amount of moisture in the air or in a material. Another way to check for moisture is to look for signs of water damage, such as mold, mildew, or rot. If you see any signs of water damage, it is important to contact a professional to have the problem inspected.
It is also important to check the crawl space or basement for moisture. If the crawl space or basement is damp, it can cause moisture to seep into the walls and floors of the house. If you find that the crawl space or basement is damp, you can take steps to reduce the moisture, such as installing a dehumidifier or sealing any cracks or gaps in the foundation.
