Basement Waterproofing questions, answered by experts

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.
