Dehumidifying Basement Mildew Solutions

A number of effective dehumidifying basement mildew solutions are already available in the market; you don’t have to seek professional help to get rid of that musty odor in the basement. A damp basement can contribute to health problems among family members and increase the household’s heating or air-conditioning bills.

Stored cardboard boxes that are u moist and moldy are an indicator that the basement needs to be dehumidified; the concrete is wet when you lift the rubberized carpet, you can smell that musty odor and you see white-powdery substances everywhere. These are just some of the tell-tale signs that it’s time to clean the whole area and get rid of that “damp” atmosphere.

Causes of Damp Basements

Damp basements are usually the result of condensation, water leakage in undetected cracks and concrete seepage. Condensation is the result of humid air that drops below the dew point and produces water.

Another practice that usually results in below-dew-point temperatures is placing carpets in the basement floor. Trapped moisture can destroy padding, adhesives and flooring, leading to additional repair expenses.

Solutions to damp basement problems include air-conditioning, sealing the basement, applying waterproof compounds to the walls, and making use of dehumidifiers and air-to-air exchangers.


Air-conditioning is not the most effective method of dehumidifying a damp basement but it still works in removing around 50 percent of the humidity present.

Air-to-Air Exchanger

The air-to-air exchanger removes humid air from the basement and draws in fresh air from the outside. It works by reducing the energy loss in air-conditioned or heated air. It’s a good solution for modern “airtight” homes. However, this solution is rather costly.

Basement Sealing

Basement sealing is considered the least expensive among basement mildew solutions. You simply seal the concrete walls, gaps, cracks and openings with a deep-penetrating concrete sealer.


Dehumidifiers are regarded as the most convenient way in getting rid of mold and mildew in the basement. Purchasing one will also help you save on repair costs that usually result from damp basements.

In choosing the right dehumidifier, it is important to know the approximate or estimated size of your house. Shops that sell dehumidifiers have charts that will help you buy the right humidifier for your house in relation to house size.

Power consumption of dehumidifiers is around $30 to $50 a month. Always keep it clean to prevent moisture and mold buildup. Constantly monitor your humidifier and empty the water canisters as needed.

In using the equipment, you can place it in the basement’s central portion. Look for gaps and leaks in the basement’s foundation and apply hydraulic concrete mixture to these leaks. You can mix hydraulic concrete in a bucket and use a putty knife or trowel to apply the mixture. Hydraulic concrete is recommended since it is fast-drying.

Waterproof Compounds

To prevent moisture in the basement walls, you can apply a coat of waterproofing compound commonly used by masons. The compound prevents moisture from forming in the wall by lessening humidity and water evaporation.
