Basement Waterproofing questions, answered by experts

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

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.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.
