How to deal with damp and moldy walls

The damp and moldy walls can be treated through ventilation and dehumidification, cleaning and sterilization, repairing leaks, using anti mold coatings, professional mold removal services, and other methods. Damp and moldy conditions are usually caused by high environmental humidity, water seepage from walls, poor ventilation, insufficient insulation, and mold growth.

1. Ventilation and dehumidification

Maintaining indoor air circulation is a fundamental measure to prevent and improve wall moisture and mold. Open windows daily for ventilation, especially on sunny days to increase air convection. Use dehumidifiers or air conditioners to reduce indoor humidity and control it within an appropriate range. Avoid drying clothes indoors or using humidifiers extensively to reduce water accumulation.

2. Cleaning and Sterilization

Thoroughly clean moldy walls and use diluted bleach or specialized mold removers to wipe away mold spots and kill surface mold. Wear gloves and a mask during operation to avoid direct contact with fungal spores. After cleaning, keep the wall dry to prevent mold from breeding again. Stubborn mold spots can be treated repeatedly, but excessive friction should be avoided to damage the wall surface.

3. Repair Leakage

Check and repair wall cracks, pipe leaks, or roof leaks that may cause moisture. The aging of the exterior waterproof layer requires reapplication of waterproof materials, while the interior wall can be repaired with waterproof putty. Wet areas such as bathrooms should be waterproofed to prevent moisture from seeping into other rooms. 4. After being treated with anti mold coating, the wall surface can be repainted with a coating with anti mold function to form a long-lasting protective layer. Anti mold coatings contain antibacterial ingredients that can effectively inhibit the growth of mold. Before construction, ensure that the wall is completely dry, apply layer by layer according to the product instructions, and focus on areas such as corners and window frames that are prone to mold.

5. Professional Services

For cases of severe mold growth or repeated outbreaks in large areas, it is recommended to contact a professional mold removal company for handling. Professional personnel will use industrial grade mold removal equipment and agents to thoroughly remove deep-seated mold, and provide wall drying and mold prevention solutions. At the same time, it can detect structural problems in the house and solve moisture hazards from the root. Long term maintenance of indoor dryness is the key to preventing wall mold. In addition to the above measures, moisture absorbing boxes or activated carbon packs can be placed during humid seasons to assist in dehumidification. Furniture placement should be kept at a certain distance from the wall to facilitate ventilation. If mold spots are found, they should be dealt with in a timely manner to avoid the spread of mold and its impact on health. If residents experience respiratory discomfort and other symptoms, they should consider the possibility of fungal allergies and seek medical examination.
