    5.0 Jean S. Edgewater, MD

    this was the best overall company I have ever had the privilege to work with. They were so helpful and afterward cleaned up so good. I can not recommend them so much. What a great company.

    5.0 Doug H. Frederick, MD

    Brother's Waterproofing is an outanding company. I developed a trust relationship with John, the ower. I got ... what he says, is what he does. I contracted with him by gentlemen's agreement, over the phone, and via texting, without meeting him in person. I knew I was not talking to a saleman. I was talking with a person who has done the work, himself. He brought in highly professional 4 man crew. He waterpoofed my basement in 6 hours. He may be a little more expensive then other contractors, maybe not. I highly recommend John. Go for it. Get Brother's Waterproofing to your waterproofing. You will be pleased.

    5.0 Becky M. Beltsville, MD

    Their attention to detail in determining what needed to be done, the quality of workmanship and materials used to fix our problem, and the care and respect they had for containing the work area and cleaning up after was all very impressive. Our money was well spent with Brother's Waterproofing.

    4.0 Kisha B. Randallstown, MD

    Great work and experience but I never received a receipt for the payment. I requested a receipt on two separate occasions but overall the work performed looks great.

    Response from Company:

    Thank you for the review Kisha!

    Basement flooded many years. Finally got help from Brothers and can't tell you how happy I am. Everything works beautifully.

    5.0 Patricia G. Hyattsville, MD

    He asseted my basement fully and explained to me what was going on under my house in layman term. He also drew a diagram and explained what was needed to repair the damage and guarentee that I would not have to revisit water proofing my basement again. I chose his company because I felt he was honest, sincere, and experts in water proofing. In addition his team were very professional in their work and left my basement clean. I was very please with the work and I have recommended this company to my friends. Patricia Greene

    Brother's Waterproofing did a wonderful job. They were finished in one day! I've had water problems for 15 years. Now I can rest assured when it rains that it won't come in my basement door. The owner was super nice. He even answered my call on a holiday! He had someone come to put my steps back even though it wasn't part of the job. I highly recommend them. John will take good care of you.

    5.0 James D. Glen Burnie, MD

    Brothers Waterproofing did an excellent job sealing a crack in my basement wall. John was very professional and knowledgeable, and that is why I chose Brothers Waterproofing over other contractors. Given I had to rip open my basement walls to fix the crack, I wanted to be sure I employed someone with a sound approach and lasting product so that I didn't have to rip open my walls again. And, John and his team did an exceptional job. They sealed both sides of my basement wall and used quality products to secure the wall to prevent leaking in the future. I would recommend Brothers Waterproofing to anyone seeking out an honest and trustworthy contractor who will stand by his product and promise (which you honestly don't find nowadays). A+ service!


    Very professional and did the job well done.
