Mold spores as most people are aware can be very harmful to health so, before you start the cleanup, make sure you are wearing a respirator mask and proper protective clothing.
Its important to realize that mold does not grow without moisture. This means that something is causing the mold to grow in your home. It could be an undetected water leak or some other water related issue. Whatever the problem is, however, you need to have it fixed, otherwise mold will just keep recurring.
Do not use caulk on areas where mold is still present. If you are going to repaint a wall with mold, make sure you have thoroughly scrubbed the area using water and detergent and leave it to completely dry. If not, the paint may start to peel.
There are some areas where mold can be found that will be difficult to remove, carpeting is one such area and it may be better to replace it. Although you can clean soft furnishing that have had mold on them, be aware that mold or mildew will generally leave staining on fabrics. Ask for advice from a furniture restoration company if you desire to keep these items.
In summary, in small areas mold can usually be cleaned up by the homeowner but seek some advice first because, as we mentioned, there are a number of factors involved.
