"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

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
