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.

    Jeanne J. of Randallstown, MD

    Customer Testimonial

              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.

    Can't say enough on how professional this crew was both Jose and Eduardo Chavez. I was worried because I recently had my basement remodeled but they very neatly covered everything up. They tested the installed system. They explained how the system functions before they left.

    Good ratings, fair pricing and good engagement and responsiveness from Jaime. In addition Sean was very informative and completed set up. My only reservation was the number of different individuals I had to interact with in order to get my project done. Admin/foreman/salesman and follow up install was a lot of confusion and conversations about not knowing what the other person said.
