“The company installed a sump pump, a dehumidifier, a backup electrical pump to meet the local code requirements. They were very professional in all respects. They cleaned up very nicely.”

Steven A., College Park

“Best Buy Waterproofing had excellent customer service from the initial call, to the inspections, and then the completion of the job. I recently hired them for a water issue in one of my rental properties. They were prompt, courteous, and went above and beyond the initial contract. The owner Andrew came out to the house twice and met with me to see how things were going. The crew was mindful of the tenants in the home and completed the job within the specified time frame. Definitely would recommend this company to anyone in need of Waterproofing services.”

Jarred U., Pikesville, MD

“I want to thank Best Buy for the wonderful job that they did with waterproofing our basement. We have had nothing but rain since they fixed it, and not a drop of water has made it into our space. We had some miscommunication about one aspect of the job, but the president of the company and one of their associates took care of it and demonstrated that they will stand by their product and service. I will definitely recommend them to others.”

Yanique R., Atlanta, GA

“My experience has been uniformly positive. Particularly in light of the very rigid time constraints under which I was proceeding, their efforts to accommodate were remarkable. Their intense labor in extreme heat conditions spoke volumes about the cohesion and good work relationship that evidently are the norm in this company. I would recommend them without hesitation for anyone considering having a basement waterproofed.”

Anna C., Alexandria, VA

“On the day of the project the crew showed up on time, was very courteous and did an excellent job! They covered all of the items in my basement with plastic to ensure that the dust from the work did not get anywhere. They answered any questions or concerns that I had. Overall, I am very happy with the work that was completed and I will recommend them to anyone I know who is experiencing water issues in their basement.”

Brett B

“We had Andrew come out to assess our basement water issue. We had 2 sump pumps installed along with a drainage system. Andrew, Mendoza and their crew were delightful to work with. I would highly recommend Best Buy Waterproofing.”

Susan R., Ellicott City

“Excellent! Quality work! So polite! Ed explained in detail with pics of what my basement needed and he came back out to see how the work was going. The contractors were knowledgeable and so patient, polite and respectful. You can tell when a company takes pride in their work when their name “Best Buy” is on the materials used. If you need your basement waterproofed then your best bet (buy) is to call the pros at Best Buy Waterproofing.”

“My husband and I are very satisfied with the work that we received. We called late afternoon on Saturday and Andrew showed up 40 minutes later and made us feel confident that we would be water free after work was done. He was very knowledgeable. To our surprise, he was able to get a crew out the very next morning (Sunday). The crew was excellent. They finished the job in one day and cleaned up all their mess. Thank you! You were all great!”

Gail and Sam Y

“Best Buy’s crew were highly trained and professional. I was really impressed with their work. Furthermore, James in particular was extremely courteous throughout the entire process. With excellent service and a lifetime warranty on the sump pumps, I couldn’t be more satisfied.”

Ola T., Montgomery County

“After the major storm from December, my basement was a complete disaster. The foundation was exposed and the wall was crumbling into the HVAC Unit. After the terrible experience with the previous contractor, I am very thankful I contacted you. You went out of your way to inspect the property the next day as promised, and were able to get the job scheduled the very next week. Your prompt and professional way of doing things took a lot of stress off of our family.”

Thomas & Margaret B

“Awesome customer service. Best Buy Waterproofing completed a job for one of my clients a few days ago. My client informed me that Andrew was very punctual and professional. The estimate for the work to be performed was reasonable and the job was completed in a timely manner. My client also stated that work crew was professional and stayed until the jobs was done. With that said, I'll be referring Best Buy Waterproofing to all my family, friends and clients.”

“I had a bad water problem in my basement for seven months. Making numerous attempts to get the Waterproofing company that I had been dealing with for years, to fix the problem. I got in touch with Best Buy Waterproofing, and was impressed with the professionalism and the service that I received. Since we've been having so much rain lately, my basement is still dry. Thank you Mr. Andrew and your staff. This is my second post.”
