"My son bought a house in Fountain City knowing that there was occasionally water in the basement that would need to be dealt with, but the torrential rains this past spring and early summer quickly moved that need from “can do later” to “must do now.” His realtor and the home inspector both recommended Thomas Waterproofing for value and quality of work. We found both to be true - while still a huge expense for a new first time homeowner, we felt the price was fair and below industry average. The job took twice as long as projected (not sure what they put in the concrete back in 1947), but was done as bid and the crew did an excellent job of cleaning up afterwards! Taylor was happy to answer any questions we had before, during, and after the job. Would definitely recommend."

"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

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Periodic inspections and addressing drainage issues prevent further damage.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.
