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.

              Wanted to thank Megan & Jayne for the professional way in which both of you and Mauricio Carvalho worked with me. I also wanted to mention the foreman, Mr. Rodriguez, who explained things to me during the work, answered my questions and offered suggestions and alternatives. He also went out of his way to purchase material and cover the hole in case of inclement weather. I was very impressed with his knowledge and professionalism, and with everyone who worked on my project, and would be glad to recommend NV Waterproofing to friends. I can see why NV Waterproofing has received such high marks from "Consumer Checkbook!" Thank you, Noah

    Customer Testimonial

              These guys were amazing. The initial visit was smooth, not pushy at all and he was even able to accommodate the relocation of a small drainage pipe. The demo to install the system was done beautifully, yes it was really good, you can tell they were precise and careful when doing so. Everything was clean, no stains on my carpet and they protected everything. No leak so far and I love it. Did I mention the price was excellent? I had 3 other companies to estimate thousands and even tried to sell extra unnecessary equipment. Thank you NV Waterproofing I have and will continue to recommend you.

    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.

Project Location: Potomac, MD 20854

Comment: Had a basement flood due to an egress window being forced open. Did the mold remediation work of removing carpeting and luxury vinyl plank floors, cutting drywall and insulation 2 feet above water mark, and now need to consider refinishing. We are interested in the flooring systems because we do not want to install flooring that will need to be ripped out if this happens again. Would consider other waterproofing ideas but this is less of a groundwater, moist area issue than it is exposure to large storms. We have a sump pump installed. Nevertheless, would want to mitigate damage if it did happen again to the extent possible.
