"I had a great experience with American Dry Basements. From start to finish, their team was professional, knowledgeable, and easy to work with. They took the time to explain everything clearly and made sure the job was done right the first time. What really stood out to me was their fair and affordable pricing—no surprises, just honest work at a reasonable cost. It’s not always easy to find a company that combines quality service with good value, but they definitely delivered on both. If you’re looking for reliable basement waterproofing with a team you can trust, I highly recommend giving them a call."

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

Basement Waterproofing questions, 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.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

Periodic inspections and addressing drainage issues prevent further damage.
