Basement Waterproofing in Bethesda, MD

"JES did an excellent job on our crawl space. We had water accumulating around the whole perimeter of the crawl space. We had also had a toilet leak causing black mold, which had been professionally cleaned up, but we wanted fresh insulation. The JES team arrived on schedule and worked diligently to remove the insulation above and the flimsy plastic that covered the earthen floor of the crawl space. They then laid rubber matting and white membrane over the dirt and put thick styrofoam on the walls. They dug a trench around the perimeter and installed 2 sump pumps and 2 dehumidifiers to deal with future water. Meanwhile a separate team arrived to put foam under our patio to stop it from sliding away from the house. Everyone called before they arrived and each member of this large team was always professional and answered all questions thoroughly. They cleaned up well each day which I thoroughly appreciate. I want to add that Brian Swain was an amazing leader and manager of his 5 to 7 man crawl space team. He kept the project on schedule, kept me informed about progress and what would happen when, and always made himself available to answer questions. Thank you, Brian! Bryan Rutherford did a great job putting foam under the patio and sealing where it meets the house. The crawl space team, Gio Ordonez, Mohamed Kamara, and Pedro Llontop worked hard each day and were always professional. Superintendent Demetrius Cooper came by to ensure everything was going well and he answered additional questions and made great recommendations. Overall the whole crew was excellent. I highly recommend this team, their dedication to doing the work well and their professionalism."
