"Installation was completed ahead of time despite a heavy rain shower. They arrived on time but forgot to bring floor covering. They called and had the covers within an hour. That did not delay the install."

"We had a great experience hiring '58 Foundations to waterproof our basement! Lon was our salesperson, and he came and explained the work that would be necessary to ensure that water would never flood our basement again. We appreciated him taking the time to explain how the whole process worked, and providing us with the option to finance the project to make it affordable for us. We had Brett Boyles and his crew, John and Clarence, come to do the work, and they did a fantastic job! Brett even came to show us the progress in the middle of the project and explained every detail of the work that was being done. He was very professional and we appreciated how he gave us peace of mind about everything once the project was completed. I would highly recommend '58 Foundations for anything basement-related. We appreciate your business - thank you!"

"The required fix required that outside trenching be done and B-Dry does not do this type of work. The representative was very knowledgeable about the problem and apologized for not being able to solve the issue. Very much appreciated his honesty."

Basement Waterproofing FAQs, answered by experts

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
