"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

"I thought my husband and I would contribute to Alex's reviews since we spent time with Jose and his team for the 3 days at Alex's house. We were amazed at how much attention was taken to ensure all our furniture and belongings were covered to mitigate dust. We are so completely satisfied with the dedication and expertise of Jose and his team. They left the basement in the best condition it was ever in. Very neat and clean, a great looking job. Kudos multiple times over for the finest production job we've seen in a very long time. They installed the interior drains and sump pump as well as a dehumidifier. No more dark, dank basement. It was an excellent experience. Thank you, Lon, Amber and Jose and team. Also a thank you to Jack Roadcap who recommended Lon to us. Warmest regards, Mary Ann Pinamonti"

"I would recommend MD Waterproofing to everyone I know. I can't praise them enough. They were so professional and sensitive to my every need. They had a supervisor who was so knowledgeable about this labor sensitive job, and the workers were courteous and hard working. When the job was completed in two days, everything was put back in place and the basement was cleaner than when they started! I am so pleased I used this company!"

"In 2007, I had the entire basement retrofitted for drainage as I was having some seepage problems in certain areas. Another waterproofing company based in Glen Burnie worked on it, however, when it came to the basement bathroom they didn't replace approximately 11 feet of pipe near the vanity and toilet. Guess what, after 6 years, that area of the bathroom started getting flooded with water every time it rained. It got to a point where I could not tolerate the nuisance that we had to put up with and tried calling the original company but they were out of business and I was left with no option but to hire another company to do the 11' of pipeline. Ameri-Dry staff came over and discussed with me the different options and we agreed upon a price. Mike and his staff worked very well in the more efficient manner on the day of the repairs. They completed the work well and on-time. It has been over two months and we have not had the recurring problem with flooding of our basement bathroom anymore. Thanks for the good service and work you did!"

"I found Waterproofing Inc. on Angie's List. The estimate was quick and easy. The crew came over a week later. They arrived at 8:15am and finished the job at 5:00pm. They worked hard and fast. This was dirty hot work and the never slowed down, amazing!"

Basement Waterproofing FAQs, answered by experts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

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.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
