"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

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

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.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.
