"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."

"We've partnered with Jimmy and the Orr Constructions & Basement Systems team on several projects, and they consistently deliver great work. They've repaired our front steps, relocated a shed in our backyard, and most recently completed a deck extension for us — which turned out beautifully. Highly recommend them for any home improvement project, inside or outside the house!"

"Nixon was amazing. I never have good experiences with handymen but he was able to fix my front door, weatherproof my doors, and fix my dehumidifier basement issue that have been huge issues before now. He’s reliable and does a great job. Highly recommend!"

"Dean did 2 jobs for me. He waterproofed my basement and rebuilt a sewage trap door in my garage. What a professional! He showed up on time, finished the job within budget and within the timeframe promised and did a fantastic job! He was easy to communicate with during the process and kept me updated. I strongly recommend Dean and his team!"

"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

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Periodic inspections and addressing drainage issues prevent further damage.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation.
