I’m trying to decide if it’s worth fixing a water problem in my basement or to just use a dehumidifier (I’m using a borrowed one, but I’m considering buying). It would help to know what the most energy-efficient dehumidifier is. That way, I can find out how much energy it uses and estimate the cost of keeping it running. Thanks for any help.

I’m glad to help. An ENERGY STAR^® qualified dehumidifier uses 10-20% less energy than a standard model. To find specific models, visit www.energystar.gov. Go to our dehumidifier section for more information on moisture, dehumidifiers, and rebates for efficient models.

I want to emphasize that it’s worth trying to fix the cause of basement water problems. If you’re able to prevent water from entering, you’ll not only lower electricity costs by eliminating the need for a dehumidifier but you’ll also protect yourself and your house from problems that moisture can cause. Those problems can include wood rot, mold, and mildew that can damage the house and items in it, and can create indoor air quality problems.

Common sources of basement moisture are outdoor air or groundwater, each with their own solutions. The latter requires a pricier fix. I suggest that you get opinions from a few contractors so that you can determine the cause of the problem and get estimates on solutions. Meanwhile, it makes sense to take some simple steps to minimize basement moisture. For example, don’t dry green firewood inside. Use an outdoor clothes line instead of air-drying laundry indoors. Keep basement windows and doors closed in the summer because warmer air from outdoors and from living spaces will condense on cooler basement surfaces.
