Get matched with top foundation drainage installers and replacers in Wilmington, DE

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"Excellent all around experience!!!!!!!! After a series of storms and gradual water soaking our basement carpet several times, I finally called Waterproofing One in April, 2017 after seeing their ad several times on our St. Basil's church bulletin. I spoke initially with the owner-Joe who was helpful and he dispatched Dave Cook who came over within an hour. Dave Cook has been in this business and related utility engineering previously for over 30 years and really knows his stuff. Dave was extremely thorough, spending time in the basement, looking at some pictures I took of the damage and spent a considerable amount of time walking around the exterior of my property and reviewing the landscaping where most problems start. Dave wrote up a report of what work was needed including extending downspouts, recommending we have our contractor add a louvered door at the top of the steps for aeration (a great idea given no windows in basement) , waterproofing the well water closet walls, spraying impacted area for potential mold, and installing a new French drain and sump-pump system with battery backup. Gene and his crew then came over on May 17, 2018 and performed the construction and installation work and did a great job. Those guys worked extremely hard in what is inherently a muddy line of work and were very courteous, professional and left the basement very clean. Gene took extra time to show us exactly what they were doing as they drilled holes into the lower cinder block walls, laying of the perforated pipe and some of the damp mold on the wooded studs he extracted at the impacted area. We paid exactly what Dave originally quoted! Dave Cook came back checked on things and made some other recommendations including adding stones around the foundation outside and in holes to avoid soil erosion and soften the acceleration of rain water into the ground. Once the work was finished and our carpenter redid the walls and painting, We had subsequently refinished the basement with high end vapor/mold resistant padding from Mohawk and a quality polyester carpet. 15 months later and here we are on September 30, 2019 after 50+ rain storms since installation and NO WATER nor Mold issues in the basement!!! We are really enjoying our basement again thanks to WATERPROOFING ONE!!!! 5-STARS!!!!!!!!"

"Basement gurus diagnosed the problem with the dry well and installed a better system than the existing one. They included points along the system to monitor the well drainage."

"Could not have been any nicer, accommodating or hard working. I would recommend them to everyone. This was outside drainage issues, not a basement project. They were wonderful. Very knowledgeable."

"Ryan provided a detailed explanation of the repair process and quoted a fair price. Erik arrived on time with his team and proceeded to repair the crack just as Ryan explained. Erik and his team were diligent and thorough. The completed the repair in the time frame promised (less than one day). They cleaned up the area when completed. It has been over a month since completion. We've had several heavy rains with no leak issues. (Prior to DryTech's repair, I had leak issues with each rain.) I would hire this company again and recommend them. Thank you, DryTech!"

"I really don't have any pros or cons they did the job right and cleaned up after themselves."

"Our experience with Martin and his crew on these jobs was overall the best we have ever had with home improvement projects. Martin was extremely professional and willing to work with us on all aspects of the jobs. Martin’s crew was very polite, , professional, clean, punctual and paid attention to detail. We replaced our tile in the foyer, and the entire time the work was going on the job site areas and house were kept extremely clean. The end result of the foyer is even better than our expectations. The front door entranceway’s surrounding woodwork was replaced and a bluestone step was added. The detail on the work is extremely good. They paid attention to the detail. I am not easily impressed, but I can easily say the work of these jobs by Martin and his crew is awesome."

"We had a French drain installed in our basement, along with two sump pumps. From what I can tell, the work was performed correctly and to the specifications outlined in the contract. I found Shawn, the owner, to be responsive, helpful, and pleasant to deal with. Overall, the crew that installed the trench and sumps arrived on time, worked efficiently, and completed the job in 3 days, leaving a clean basement behind. For the sake of fair balance, I will detail two issues in the service I received. The first had to do with the condition of my footer when the trench was dug. As they were digging, I noted that in one section of the wall, the footer appeared have been damaged by their jack hammering. Upon calling Shawn about this issue and sending him pictures of the damage, he stated that it was related to how large the footer was and how the footer was poured when the house was built. He also assured me that the footer was in good condition and the part they chipped away was not load bearing and had no impact on the structural integrity of the foundation. This seemed to be a reasonable explanation so I thought nothing of it. The second issue had to do with cracks in the basement floor. Before the work was started, there were one or two visible cracks in the floor. Yet, after their work was complete there were well over a dozen visible cracks. Upon calling Shawn again, he stated that his jackhammers could not have caused that damage and there might have been smaller cracks that got larger when they began working. I do not have photographic proof to dispute this explanation so I can only cite my memory regarding the condition of the basement floor; however, in combination with the first issue it makes me wonder how much care was taken when they dug the trench. Not being structural engineer or having photographic proof, I can not refute the explanations given to me, but my advice to others would be to photographically document the condition of your basement prior to getting work done and carefully watch the work being performed."

"Dave came out to give me an estimate on fixing what I was hoping was down 3 ft dig, after explaining my options I chose to go all the way down 6 ft and I was happy that I had. Alex the owner and his crew came out, they dug out the foundation, showed me where the cracks were and came back the next day to finish fixing the cracks installing the waterproof barrier, regrading and filling in the trench. They were professional, on time and amazing to deal with. When they left you would not have known they had been there except for the lack of grass on that side of the house. I would recommend this company to anyone needing their foundation fixed"
