Basement Waterproofing FAQs, answered by experts

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
