Basement Waterproofing questions, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

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.

Finding water under your sink can throw a wrench in your day, but acting quickly can prevent water damage. Soak up water with a towel, then put a fan or dehumidifier near the open cabinet to dry it as fast as possible. If any mold or mildew has formed, you may need to replace the bottom of the cabinet.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.
