Basement Waterproofing questions, answered by experts

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. 

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

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.

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.
