Get matched with top foundation drain installation pros in Lanham, MD

"I think it went well , although the drain hasn't really been tested by a heavy rain yet."

"John from AA Waterproofing showed up on time to analyze the water problem coming through my foundation. He showed me a video that gave me all the alternatives to fixing it with the internal French Drain showing the best results - and warrantied for any future problems for both me and anyone who buys my house in the future. Although this is not an inexpensive solution, it appears to be the best. John did a nice job of responding to all my questions both during the inspection and afterwards. I did do some research on the costs and AA's bid came in down the middle range. The crew (4 men) showed up on time (actually an hour early) and immediately got to work covering all the steps down to the basement and the front entry way. They also put plastic covering over all the stuff in the unfinished basement. The work went quickly and neatly as could be expected. Sam, the foreman, did a good job of answering my questions and showing me the progress. They had 70 feet of internal digging and piping to be done to connect to a new sub pump that was part of the bid. All in all, the job too two days (much faster than anticipated) and looks good. After cementing (special hydro pressure cement) the wall where the crack existed, Sam also installed an extra mold proof walling over the that area. Overall, the work looks good with a nicely done cementing of the drain around the perimeter of my basement. So far we have not experienced enough rain to test the results, but I feel confident that this was the best solution done by a very competent company."

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"We moved into new house and quickly found out the basement had major water issues due to years of neglect (including a clogged and poorly installed English drain from years ago, and a sump pump that while it worked, never pumped water.). Given the investment we made in buying the house, we wanted to make sure we left no doubt in our mind that we were fixing it for the long haul so we could use the basement without worry of mold/mildew for our kids. We had NV Waterproofing install perimeter wide gutter guards, and a new sump pump system and drainage pipes. As soon as the work was done we got rain, and for the first time in the 4 months since we have lived here I saw the water that otherwise would be in our basement actually in the rear of our backyard by the discharge pipe. We have had a few more rains and even one snow and there is nothing better to look at then when I see the water that is coming out of the discharge pipe that I know otherwise would be pooling in my basement and cynderblocks walls, and how that was the case for many years before we moved in. Also, the team that did the work was extremely professional. We have 3 kids and pets and the team was extremely courteous. We tried to stay out of their way during the week they were doing the work, however there were times when we couldn't and the team was extremely courteous and professional. The team lead did an amazing job of explaining to me the work he was going to do, showing me updates, and then afterwards explaining in detail what was done, why it was done, and things for me to look for for in the future. I would highly recommend NV Waterproofing to others based on my experience with them. They did high quality work and were extremely professional."

"All Aspects Waterproofing installed a French Drain and new sump pump in my basement. The project also required adding a curb to the foundation. From the estimate to project close out, all of the employees were great to deal with - very responsive to emails and calls with questions and pro-actively called me to keep me up to date throughout the process of getting the permits and inspections, coordinating with my plumber who took out and installed new hot water heater, and coordinating with my own schedule. All of the workers who came and did the hard work were great - they worked very clean and went above and beyond helping remove items I needed to have out of the way for their work and left my basement and yard (where they needed to do some of the prep like making concrete) spotless. They were great - responsible, knowledgeable, honest, friendly, reassuring - and I would totally use them again. Also, great value."

"The Technician Joseph came promptly, changed the garbage disposal and unclogged the drain line quickly within a couple of hours, great job and I am very satisfied with service. Highly recommended."

"Was polite and professional but didn't have the tools needed to properly unclog my underground gutter drain which was clogged with roots. Tried a mechanical auger that he had but that was all he could do and only pulled thin roots which helped but didn't completely unclog the drain."

"Van confirmed appointment, gave estimate and completed the job as discussed. All drains are in working order."

"I contacted them in the morning and the drain was fixed later that afternoon. I would highly recommend Tawn...very hardworking."

"Outstanding. Showed up within 45 minutes and quickly fixed the issue of a clogged basement drain."
