Why Do Maryland Basements & Crawl Spaces Get Wet?

Flooded basement: Maryland has an annual precipitation that averages about 40 inches statewide, plenty to cause flooding and water damage. When flooding hits your area, your basement is most likely to be the prime target for water damage.

Other wet basement signs: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

    Customer Testimonial

    Amy G.
    Milton, DE
    Amy G. lives in Milton, DE with her her family. Her young daughter was experiencing asthma issues. Her asthma was being negatively impacted by the air in the home. The wet, unconditioned crawl space was not a good environment for the health of family. Phil came in and helped walk the family through all of their questions and concerns. He even "showed up a little bit early" which impressed the family from the start. Phil accommodated the family's schedules and did what it took to get the family feeling better again. When Bill, the owner of DryZone reached out and asked the Amy and her family, "Where do you want to be? What do you want to see happen?", the family knew that there was only one answer which would guarantee good health for their family. They chose DryZone and are thrilled that they made that choice.

    Customer Testimonial

    Norbert K.
    Millsboro, DE
    When Norbert K bought his house in Millsboro, DE, it already came with crawl space that was encapsulated by DryZone Llc., and was therefore covered under our Transferable Lifetime Warranty -- even though the previous homeowner had failed to keep up with the annual maintenance schedule. Encouraged by the home inspector and by the brochures that accompanied the Warranty, Norbert concluded that it was a good idea to not only keep the current system installed, but get it back on track with a maintenance schedule. Sp he gave DryZone Llc. a call and one of the owners, Heather Anderson, personally answered to the questions he had about the system and the products. During that conversation he decided to add a battery-operated backup sump pump to his system for an extra layer of protection. He was quite impressed with the service person who came to his house as well. "Very intelligent because he answered to all the questions I had To me this is brand new! I had a lot of questions for him and he was very courteous and answered to them." Norbert is very happy with his encapsulated crawl space, and so are his grandchildren: "It just stays nice and clean. As a matter of fact my grandchildren even say that it is like a house under our house. They would like to put sleeping bags under there." -- he says. How much does he like his crawl space encapsulation system? "If I had another house I would put it in! I would recommend it to everybody. It is the best thing that ever happened to the bottom of the house!"

    Sally H.
    Ocean Pines, MD
    Sally H moved from Vermont to Ocean Pines, MD, and quickly noticed a problem with standing water in her yard. Concerned about the potential for water to seep into her crawlspace and lead to issues with mold and the structural integrity of her home, she decided to take action. After initially reaching out to another crawlspace repair company without any response, Sally turned to the trusted experts at DryZone. Like many homeowners, Sally approached her repairs in phases. In 2017, DryZone installed the Hydrolink Drainage System, a Triple Safe System, and an EverLast Crawlspace door for her. Fast forward to 2025, Sally recognized it was time to fully encapsulate her crawlspace and once again contacted DryZone to get the job done right.

    The install was very smooth I remember it was snowing, we started this process in March. The guys took a great amount of care to make sure they didn't trash the house. They kept everything neat and clean jackhammering concrete is a little bit loud but it didn't take very long. From seeing the bright white basement you had no evidence workers were there. Hurricane Irene was perfect for us, we were able to spend most of our time helping out others because our basement was nice and clean and dry. The only time I got soggy was helping out friends who hadn't had basement work done yet.

    Stonewater Creek, in Millsboro, De, had a party for their community planned to celebrate Memorial Day, but they found a problem surrounding the community pool. Underneath the concrete, they found that the soil under it had started to settle, creating a void, with nothing supporting the concrete. After doing research they learned that removing and replacing the concrete would be a very timely and costly job, pushing back their celebration WEEKS. In their research, they found DryZone and our PolyLevel concrete lifting service. We were able to get the job done, and the concrete supported, just in time for their Memorial Day celebration to go on as scheduled! Listen to what Rich has to say about his experiance with DryZone.

    Jordan and Donny were great to work with. I had a sump pump replaced and floor drain installed along with a fabric to protect from water intrusion through a small crack in the foundation. Jordan called me with an ETA, which was very helpful for planning, and they arrived right on time. They put down covers on my stairs and flooring to protect my home and cleaned up after themselves. Jordan explained every step of the process and further explained how to re-install the insulation once the concrete was dry. The work was completed in a little over 2 hours and the pump is working well. Jordan also explained the warranty on the work. I would recommend this company and this crew.

    From start to finish, I received stellar customer service from everyone I encountered when inquiring information about my crawl space...from every person who answered the telephones and my accompanying questions, to the person assessing the situation to the actual team completing the job. This company employs PROFESSIONALS!!!!Thankfully, they were able to schedule an appointment quickly. After assessing the situation, he recommended encapsulation of the crawl space, providing multiple views via supporting photographs to further explain their services and the process.I then contacted her, who performed a miracle and scheduled the encapsulation quickly in less than 2 weeks, April 8, 2022 to be exact.Throughout the process, they kept me informed via telephone calls, emails, and text messages. Due to their sustained excellence and quality customer service, I was fully prepared and had no doubt the tasks would be completed efficiently.The foreman, called me April 8 to provide his estimated time of arrival. I met him at my house along with them around 9:15 a.m. All three men were pleasant and I felt comfortable with the information and explanations they provided.I left my house while they performed the tasks at hand. Since the house is vacant and the chemicals, etc. they were using can be harsh, I left them to their own devices. He telephoned me around 1:40 p.m. to say they were finished, cleaning up, which was much sooner than their earlier estimated completion time of 6 p.m.When I returned, he provided explanations of the work provided as well as photos of their work and a tour of the exterior work completed. I am beyond pleased with the service I received and HIGHLY RECOMMEND them to my friends, family, and enemies too. Everyone should support this company, as they are credits to their profession.They did phenomenal work and I'm glad they were assigned to handling this job! Thank you for every kindness you extended and all our professional encounters.

    Mauricio explained 3 options that would fix the water problem we were having in our basement. He gave me details about the materials and process NV watering proofing would be using in my home. He never tried to sale me something I didn’t really need. Rich arrived on time. He walked me through what he was doing. He put everything back so well, you can’t tell any work was done on that wall. I would definitely recommend this company and their crews!
