"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!"

"Very neat with their work in a messy job. Laid down protective flooring to prevent mud from being tracked through my house. Went from a basement with ankle deep water to a waterproof basement with no water in the basement even after tropical storm rains."

"John and Steve responded to my inquiry quickly. The price was very reasonable compared to another company I received a quote from. Plus they were willing to give me more waterproofing protection than the other company. This business recognizes first responders and veterans. I was able to get the project started quickly because of that. I highly recommend them."

"We called 3 companies about our basement leak . Jeff responded immediately. He came over right away and gave a fair estimate for the job. He was back in 2 days with 3 workers. Leak was remedied . Everyone worked so hard on the inside and outside of our basement. We had a huge storm the next day. No leaks!! Jeff called on Christmas day to check on the job!! I would highly recommend this company. They are courteous, professional and know their stuff. Jeff is a pleasure to deal with."

Basement Waterproofing questions, answered by experts

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

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.
