"The team worked diligently and professionally to Waterproof my basement after hurricane Helene caused water to come into my basement. They had to dig down into the foundation, fix the crack and apply waterproofing underneath my patio. While we haven’t had any big time rain since then, it’s been working against any kind of rain happening so far he also guarantees his work which gives peace of mind. They also encapsulated my crawlspace. It looks very professional and well done. It helps keep the humidity down in my crawlspace, and thus and the rest of my house. I would certainly recommend them to anybody who needs waterproofing solutions."

"Regarding project #118. I'm so happy that I found them. I have struggled to find the right people to complete the necessary work to fix my water problems once and for all. After spending thousands of dollars with different places I can officially say that Asheville Waterproofing is honest, reliable, knowledgeable, and a team of highly skilled people. I had never used home advisor, but I needed to try something different, and I"m glad I did. Thank-you Will, Dave and Moses for your time and energy to get this completed as planned. For anyone who is struggling with ongoing water problems due to increased amounts of rain you should consider seeing what this company can do."

"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 questions, answered by experts

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.
