"Dalton drove out to the ranch outside Rapid City, SD several times to take care of the shower and the kitchen sink. My mom is 90 years old. Dalton not only fixed everything, he also was so kind and courteous to my mom. When mom mentioned the roof had a hole in it. He climbed up and took pictures. He then recommended another employee to come out and fix the roof. I could not have asked for a nicer, professional and kind person to come all the way out to the ranch to take care of my MOM. I highly recommend Loyal Plumbing Heating and Cooling for all your household needs and fixing. Thank you."

Basement Waterproofing FAQs, answered by experts

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
