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.

    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, Jeff recommended encapsulation of the crawl space, providing multiple views via supporting photographs to further explain their services and the process.I then contacted Amanda, 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.Bernie, the foreman, called me April 8 to provide his estimated time of arrival. I met him at my house along with Fernando and Edgar 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. Bernie 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, Bernie 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.Karrie, Amanda, Ashley, Tina, Jeff, Bernie, Edgar, and Fernando 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.

His competence was evident and his modesty sublime.Under Estebans guidance, his crew helped to make a "dreadful project" (my words), a truly positive experience.

    Rob, We just wanted to let you know what a terrific people you have working for you. We have had such a wonderful experience with your DryZone crew. Johnny is a superb salesman. By the time he was finished showing and explaining your products to us, we wanted it all. Obviously due to financial reasons, that was not possible, so he designed a system that fit within our budget to solve our biggest issue which was a wet basement. Todd did a wonderful job installing our new windows and they look great. He also gave us, and Josh a head up that the WaterGuard system would not fit our basement as Johnny had thought. I have to admit that I was disappointed when I had heard that. Josh, Mario, Carlos, Taladro, and Sergio said the they have never had concrete that was so hard to remove! However, they kept at it an the installation of the FlowGuard system, TripleSafe sump pump, and SaniDry looks great. I was wondering if you offer a maintenance program for the systems? So far, with the very wet spring that we have had the basement has stayed perfectly dry! Exactly the results we had hoped for. Please feel free to add us to your references if you would like. Thank you, Julie & Susan B.

    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!
