"We recently had our basement waterproofed by the American A-1 Waterproofing Company, and I couldn't be happier with the job they did. From start to finish, the team at American A-1 Waterproofing was professional, knowledgeable, and dedicated to ensuring that my basement would be completely waterproof. First, the team came out to assess my basement and provide me with a detailed estimate of the work that needed to be done. They took the time to explain the process to me, answer my questions, and address any concerns I had. I felt like they really listened to my needs and customized their approach to fit my specific situation. Once the work began, the team was punctual, respectful, and efficient. They took great care to protect our home and belongings, and they kept us updated throughout the process. They worked quickly but thoroughly, and we were impressed by their attention to detail. The waterproofing work itself was top-notch. The team used high-quality materials and techniques to ensure that every nook and cranny of my basement was completely sealed and protected from water damage. They also installed 3 sump pump and created a French drain to further safeguard our home. A-1 did a great job waterproofing our flooded and leaking basement. They kept coming back as bigger rainstorms showed smaller leaks and waterproofed the inside and outside until stayed dry. Overall, I highly recommend American A-1 Waterproofing for anyone in need of basement waterproofing services. They are professional, knowledgeable, and dedicated to ensuring customer satisfaction. Thanks to their hard work, I now have a safe and dry basement that I can enjoy for years to come!"

"Weather-Tite was recommended to me by a contractor who I trust to evaluate and repair water and moisture issues that I was having in my garage. Bob and his crew did a phenomenal job!! My husband and I are beyond thrilled with the results! They are professional, courteous, and fastidious. Half of my garage is underground, as there is a hill in my front yard leading up to the house. The repair involved excavating dirt along the front of my house next to the garage foundation wall down to the drain pipe, repairing cracks and holes, applying waterproofing and more. The interior wall was cleaned and drylock masonry paint was applied. My landscaping on the outside had to be removed and then put back. They did such a good job that you couldn't even tell it had been moved at all. We also had Bob and his crew complete a second job for us. This involved excavating another trench but in the back of the house along 16 feet of the foundation, replacing a drain pipe and waterproofing. They were at our house for three days. During that time and after we had torrential rain and everything stayed dry!!! I highly recommend Weather-Tite Waterproofing, Inc.!"

"National Pro Waterproofing did an amazing job in our basement. Mike got us scheduled quickly, was professional and addressed any concerns I had. He showed up on time with his very experienced crew and they got the job done in one day. They worked quickly, neatly and even put up a plastic barrier to keep the dust from spreading out of the work area. They left the work area immaculate. I highly recommend National Pro Waterproofing!"

Basement Waterproofing FAQs, answered by experts

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.
