Dampness in the home especially the basement can be a cause of unwanted and excessive moisture that will eventually lead to the formation of mold, bacteria, and fungi that can be harmful to your health. Spring rain is just around the corner, and if your basement has leaky problems that let water accumulate on the floor or the walls show dampness, you need to contact a reputable company to fix the problem right away.

Living Smart: Basement waterproofing methods
Waterfalls and water fountains soothe the soul. Water in your basement stirs up anguish.
There are several methods to keep water out of your basement or remove what gets in. The most expensive, as well as the most effective, can require extensive excavation, our researchers learned in interviewing homeowners and highly rated contractors.
Interior-based waterproofing methods, often called “negative side” projects, involve moving out water that’s inside the home. Fixing a water problem from the inside may be a cheaper option, especially in cases where exterior work isn’t practical or possible.
Drain: This system moves water out of the house through a hole or trench in the foundation, paired with a sump pump. Such a system should also include insulation of basement walls, with a vapor barrier to protect against condensation. Drainage systems start at around $2,000.
Sealants: Some highly rated waterproofing companies don’t recommend sealants because they say they fail too easily. The cost of a sealant-based waterproofing project may range from $4 to $8 a square foot.
Epoxy injection: Like sealants, this option is not always favored because it may provide only a temporary solution to fill cracks in poured-concrete walls. Epoxy injections can start at $300.
Moisture and Mold Prevention and Control Tips
- When water leaks or spills occur indoors – ACT QUICKLY. If wet or damp materials or areas are dried 24-48 hours after a leak or spill happens, in most cases mold will not grow.
- Clean and repair roof gutters regularly.
- Make sure the ground slopes away from the building foundation, so that water does not enter or collect around the foundation.
- Keep air conditioning drip pans clean and the drain lines unobstructed and flowing properly.
- Keep indoor humidity low. If possible, keep indoor humidity below 60 percent (ideally between 30 and 50 percent) relative humidity. Relative humidity can be measured with a moisture or humidity meter, a small, inexpensive ($10-$50) instrument available at many hardware stores.
- If you see condensation or moisture collecting on windows, walls or pipes ACT QUICKLY to dry the wet surface and reduce the moisture/water source. Condensation can be a sign of high humidity.
