    I would highly recommend basement waterproofing nationwide. Mike Milton and company were professional and knowledgeable about my garage water issue and sump need. They addressed the problem in a timely manner and were honest about the issue. Haven’t had water issue since they fixed the problem. Their price was also very reasonable compared to other quotes I got. Thank you guys!

    Had a great experience with BWN. Was dreading the prep (on my part) and the process itself, but am pleased to say it was so much better than expected. Frank and his crew were professional, knowledgeable, and respectful. Salesperson Mike T. went above and beyond helping me before and after to make the entire experience pleasant and worthwhile.

    Clean up was very good. Overall job looks good. Kept it neat and orderly throughout the project. Friendly people. A little expensive I believe. But very attentive and great customer service. Also has a lifetime-transferable warranty. So really it all comes down to value. I would definitely recommend.

    They completed the project on time and were considerate of our belonging. They responded to our call the first time we called. The workers cleaned up each day before the left and returned on time each day.

    My wife and I have been putting off this project for many years. Situation worsening every year. Finally had enough and contacted (Steve) from BWN. Didnâ  t even feel the need to get other estimates because I was so pleased with our first encounter. Had rather extensive work done which included waterproofing ,carbon fiber straps, jackhammering done for new drain system, new sump pump and liner and new outside window well installed with drain. Can not stress enough how happy we were from start to finish. Workers were on time and extremely courteous!!!! Very impressed with cleanup as well. No only final cleanup but each day as well. Shout out to Jeremy who was our contact coordinator thru the process who went over and above to assist with paperwork details and help me with online support with finance company. BWN offers financing thru Power Pay. Had a little trouble setting up account but Jeremy bailed me out. Also pleased at this point with Power Pay.

    5.0 Elise R. Baltimore, MD

    I had a window and door in my basement that had simply been closed off with plywood. My basement regularly flooded because the sump pump couldn’t keep up. Basement Waterproofing Nationwide blocked up the openings, installed a new French drain and sump pump, and put in a new vapor barrier. I haven’t had water in my basement since. I strongly recommend this company. They do amazing work.

    5.0 John A. Perryville, MD

    The job was done in a quick and timely way, without any problems. I am A satisfied customer.
