"We just had American Dry Basement install a waterproofing system in our basement. We've had issues with water in our basement and needed a total solution so we can sleep at night and go away without worrying about flooding. Steve T from American Dry came to our house and presented us with what the solution will look like and thoroughly explained the entire process. He also answered all our questions and was always available to talk to. He is extremely knowledgeable and an excellent professional to work with. Then Wilson and his two-man crew came to do the work and they were all professional, extremely hard working and respectful of our home. They always started early and worked all day long to get the job completed. They wrapped up all items that were still exposed after we cleaned out most of our basement, used vacuums and filters to minimize all the dust and left our basement cleaner than it was before. We highly recommend American Dry Basement Systems and we're so happy we chose them over the others we received estimates from. And their price was more than competitive for what we believe is a much better solution."

"Nixon and his crew did an outstanding job gutting and rebuilding a very challenging bathroom in our house, which was built in the 1930s. We are very happy with the craftsmanship and the price, and it was a pleasure to work with them on this project from start to finish. I highly recommend this excellent contractor."

"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."

"Called Dean with an emergency on a raining Sunday after turning to Angieâ s List to get my sump pumps working. Had never used him before. He came immediately. He got 2 of 3 working and replaced the third. Got everything set back up and running. Charged me only $150 ona Sunday plus the cost of the new sump pump, which was about the same as the last time I got a new pump from a plumber. Knows his stuff, friendly and reasonable. Would definitely recommend."

"Flooding in our basement has been a recurring problem over the years. We’ve had various companies do work for us but they failed to keep our basement dry for longer than a few months at a time and only did a semi okay job. That all changed when we hired Empire Construction Waterproofing. Chris gave me a very reasonable price for the size of our project. They had a team down there starting to work almost right away! They were incredibly professional and worked very efficiently. Once they were done they left the space in great condition. My husband and I were very satisfied with the project. The results went above and beyond our expectations, the quality was unlike anything we’ve ever seen before. It was such a pleasure working with Chris and Empire Construction Waterproofing. I have recommended them to all of my friends and family. If you’re having basement issues definitely give them a call."

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.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.
