"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!"

"Quality craftmanship, true to commitment, utmost professionalism, reasonable cost, and more... Century Masonry and Waterproofing are outstanding professionals, providing quality service and product at a reasonable cost. Besides their exemplary work ethic, they are kind, thoughtful, caring and respectful people, going above and beyond to help us. They treated my family with kindness and concern, helping out with things not required of them as my husband's recent illness prevented him from doing some of the work he committed to doing previously. I was in awe of the humanity they showed my family. In fact, my young granddaughter keeps asking if they could visit again! My family and I would HIGHLY recommend this company. Sincerely, Dawn"

"Joseph and Sons had done our waterproofing in our finish basement. What I liked about this company was, they were the only company to do waterproofing and finish our basement with Sheetrock, trim, trim and floors. A one stop company that does all. Always delt with Angelo and he was very knowledgeable. Will be using them for future jobs."

Basement Waterproofing FAQs, answered by experts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

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.
