Basement Waterproofing questions, answered by experts

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.
