    This company did an excellent job.


    They were prompt, courteous, reasonably priced, and solved our leak issue in the basement. Great job!

    5.0 Evelyne H. North East, MD

    These guys were prompt, courteous, and solved a water problem that I've been struggling with for several years. They did a good job for me. I recommend them.

    4.5 Denise C. Parkville, MD

    My entire basement was waterproofed over 20 years ago. Water was coming in again, so the salesperson recommended I have the waterproofing on one wall re-done, a vapor barrier installed on that wall, rebar inserted in 3 places inside the wall, cinder blocks in those rows filled with concrete, & a sump pump that was less than a year old - replaced. I was not at all happy with the fact that they required me to replace such a new sump pump in order to get the full warranty on the project. However, I was very impressed by the tons of good reviews I read about this company and the fact that they've been in business for 30 years. I must admit, I was also feeling very good about only having to pay a little over $5,000 to resolve such a scary-looking situation (my block wall was sliding off the foundation)! My relationship with the company really suffered on the first day of the project. Jaime (the project leader) advised me that I should really have the wall reinforced with steel beams, which would cost an "additional" $4,000+, and that I might also want to consider reinforcing a second wall with carbon fiber straps, which would cost another $5,400. Everything he said made sense, considering the looks of things - and I believed him. My issue was, why wasn't that information given to me by the salesperson? It felt very much like a bait and switch situation. By this point, work was in progress and my concrete flooring had been jack-hammered up in front of the worst wall. Considering the costs were now soaring, I said I wanted to get additional estimates to compare with theirs, before having the more extensive work performed. Jaime contacted John (his boss), who insisted they complete all work that had been contracted thus far, including replacing the concrete section of the floor. "Won't the floor have to be jack-hammered up again, in preparation of the steel beam installations," I asked? He confirmed that to be true. I argued that it didn't make sense to spend the time & money pouring the concrete when their crew, or the crew of another company would just have to tear it back up again. He was pretty adamant, but I was even more so, and the floor stayed open while I obtained the other estimates. I realize they wanted to have enough of the work completed to collect payment, which I paid in full, without question. But I really did not appreciate this added stress to an already stressful situation. I did hire Basement Waterproofing Nationwide, Inc. to do the additional work on the worst wall. I still have faith in their expertise, Jaime was very knowledgeable, the crew did great work and really did a good job keeping the mess to a minimum. After all the contention between John and I, we even ended on a good note. I hope Basement Waterproofing Nationwide, Inc., will be more understanding of the customer's position the next time, if they ever encounter such a change in project scope again.

    Work crew was excellent. Arrived on time. Made a mess but cleaned every bit of it up! Worked constantly, quickly and thoroughly!! Crew leader was very knowledgeable and explained everything they were doing. Would definitely hire again, but hope I never have to do so!!!

    5.0 Jaye R. Randallstown, MD

    I appreciate the detail of the initial consultation. The work crew was prompt and courteous, providing me with a status update at each day's end (3-day job). I am so very pleased with the outcome!

    Response from Company:

    Thank you Jaye for your kind words regarding the initial evaluation and installation process. We're confident you will be equally pleased with the results of the project - a dry basement. Mike Tilton- BWN Representative

    5.0 John G. Newark, DE

    A first class company all the way through the entire process. Highly recommend

    Response from Company:

    John, I'm so glad we were able to repair the crack in your wall, and that you are pleased with the result. Kim Shibley- BWN Representative


    I would like to offer the following feedback. Customer Service. .5 Stars..I submitted my request Saturday, January 21st and my job was completed Monday, January 23rd. I spoke with Steve and he was very attentive to my plumbing issue. I selected the company based on reviews and the fact that I could get two services from one company. This was a plus for me. Jan 23rd. I received a call from John and it was a pleasure speaking with him. I provided me with an update regarding the techician (Joe). Joe called in advance to let me know his projected arrival time which I greatly appreciated. Some things could have been done differently.

    Response from Company:

    Thank you Cynthia for sharing your positive BWN experience with others. Your kind words are greatly appreciated. We strive to provide superior customer service from the initial contact with the customer till the project is completed. If we can be of any assistance to you or any of your friends or family in the future, please do not hesitate to call us. 410-679-2000. Enjoy your dry basement! Rachael Doddato BWN

    5.0 Jacqueline C. Baltimore, MD

    BWN was prompt, sent courteous representatives and knowledgeable technicians who went above and beyond in explaining and completing the process. They were also reasonably priced and were the only ones to offer a lifetime guarantee. I would recommend them to others. They left the worksite clean and I have not had any other problems with my basement.

    Response from Company:

    Jacqueline, it was great working with you. You did your homework both on the recommendation and our company. Thank you for explaining how you made your choice. Please feel free to recommend us as we strive to serve all our customers as we did you. Kim Shibley - BWN Representative
