How to remove mold from walls

By | June 16, 2016

Mold is a form of fungus that grows in the damp areas of wall, that remain untreated for a long period of time.

The damp can come in from various places like the ceiling, or a leaking water pipeline adjacent to the wall, or the edges of the window frame or even the basement. Mold (also called Mould) starts growing in these areas with excess moisture and then slowly spreads out. It appears black in color and looks very ugly.

Most of the time such molds appear in houses that are old an not maintained properly. Mold can even appear on the outside of the house if there is a lot of wet soil touching the exterior walls. The damp can move up from such soils in rainy season providing a favorable environment for mold to grow.

1. Treat any leaking water lines

The first thing to do is to make sure that there is no leaking water touching or reaching the walls anywhere. All water must flow only through the pipes.

Call a professional for doing an inspection of your bathrooms and kitchens and where ever there is damp or mold visible.

This involves spending quite a lot of money but is essential if you wish to fix the problem permanently.

2. Fix leaking roof tops

Apart from leaking water lines, another major cause of wall mold is the leakage from roof top. If the insulation is not properly done, water from the roof top can seep into the ceiling and other walls making them damp slowly. The problem will be more evident during rainy season.

Check your ceiling for weak insulation and get it fixed.

2. Get ventilation and sun-light

Closed places have moisture trapped which eventually lead to the growth of molds. The effect is pronounced during rainy seasons when the weather is more humid. Humid environment provides a more conducive environment for molds.

Best practice is to ensure ventilation all across the place. Open up the windows, and turn on the fan. Get more air in and out. Also get some sun shine when ever possible. Open up the windows during morning and afternoon when there is plenty of it. Heat from the sun prevents the growth of these germs inside the house.

3. Removing mold from the wall

Once you have managed to fix all other problems like damp, leaking water and lack of ventilation, its time to clear off remaining mold.

Take chlorine bleach and mix it with water. Mix about 1 part bleach with 3 parts of water. Alternatively you can use a detergent with bleach as an active ingredient.

Take a brush and scrub the blackened area of the wall using the mixture made about. That should remove the mold completely.

Once done, let the walls dry. Turn on the fans if any.

This formula should work well with painted walls.

4. Use commercial mold removal liquids.

You can use some anti microbial or anti mildew solution to wipe on the walls to prevent molds from growing again. They can be found on amazon.
