"A home inspector recommended Taylor Waterproofing, saying it was a quality company that had reasonable pricing. When I called, the owner said he was booked beyond when I needed the work done, but after considering a moment, he said he would get the work done even if it meant working late or over the weekend. He kept in touch, so i never worried that the work wouldn't happen. When I met his team, I was very impressed with their professionalism and their kindness. The work was done well within my time constraints! My crawl space was left perfectly clean; he did way more than I expected. Working with them was a great experience!"

"I had Ameri-Dry Waterproofing come to my house to inspect a water problem we

were having in our basement.  We found the inspector, Barry, to be very

knowledgeable and very thorough in his inspection.  He explained everything

to us and answered all of our question, which we had many.  At the end of

the inspection we all sat down and went over our goals and expectations.  We settled on the

Ameri-Dry drain system and found the price to be fair.  The full warranty

was the clincher for us.  They installed the system in less than a week and

I must say the men were very courteous.  They worked very hard and finished

the job in under four days.  The foreman, Barry, ran his crew very efficiently.

Everyone had their job and they performed them to my full satisfaction.

Even though we had dust they cleaned up nicely. I highly recommend Ameri-Dry

and would hire them again if I ever had the need.

"Maybe I should wait until it rains to make sure everything works (LOL) but I'm so excited about the work Zelica just did in my basement that I felt compelled to review them right away. Every step of the process, from their initial free estimate, to the work itself, to the communication throughout was excellent. We have not always had the best experiences with companies doing work on our house here in Western North Carolina, but Zelica has been amazing. They were always quick to respond to my inquiries, super informative, and fairly priced. They worked their butts off to get our basement waterproofed in less than three days and it looks fantastic (as fantastic as a waterproofed basement can look). Highly, HIGHLY recommend Zelica."

Basement Waterproofing FAQs, answered by experts

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
