"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!"

"Right before Christmas, I had called AJT for a chimney sweep and to talk through some potential concerns i had. I had other companies coming over prior to this visit to check out my chimneys and it quickly became clear that they were trying to charge me for work that wasn't needed and were clearly overpricing the work. I had the pleasure of speaking with Mike, their foreman, about my concerns i had and he was excellent. Went above and beyond to check out my chimney, take pictures, and talk me through my original concerns around waterproofing and the cracks in my chimney crown. He talked about industry trends in the chimney business and was very knowledgeable about this line of work. I've dealt with my fair share of contractors and foreman and people like Mike are hard to come by. An honest, straight shooter who will tells you like it is."

"Cesar remodeled our basement, and we cannot be happier with his work! He worked with us the whole way to make sure we were happy with the work. He even put a custom wine rack in. The new basement is so beautiful and we get so many compliments. He has done work for us before and he does excellent work, is always available and easy to reach, and has a professional and kind team of workers. Thank you Cesar!!"

"Wilmer and his crew do a fantastic job. We had serious drainage issues in our backyard and it was leading to water in our basement. Not only did he fix the problem with perfect engineering precision, but he made the back yard look cosmetically beautiful. Youâ ll love his work."

Basement Waterproofing FAQs, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
