Get matched with top foundation drain installation pros in Elsmere, DE

"This was a huge job. A complete basement waterproofing - new internal drains installed and two new sump pumps installed. The guys were great - came on time worked hard all day and cleaned up after themselves. The only negative was at the completion of work when it was time to pay the amount was less than what was originally quoted. I told the guy that and he insisted that it was what he had. I even showed him the quote on paper. I paid it - glad it was less, but a few days later got a call from the office telling me I needed to pay another $1600 (the difference between the original quoted price and at the time of service price) I told her what the guy told me and she got a little rude saying "well you knew what the quoted price was" - yeah I DID know and was prepared to pay but after install HER guy insisted it was the price he had. I wasn't trying to get out of paying but the confusion on how much it costs was with the people working there. I didn't appreciate her attitude as if I was trying to skimp out of paying. Nevertheless, I ended up with this additional payment. However, the work is supposed to be guaranteed for life. No complaints there."

"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!!!!!!!!"

"Excellent work. Right after the installation, hurricane Ida hit. Not a drop of water. It all went to the French drain system, if anything penetrated. The smart jacks will prevent further buckling in the house due to secondary settling. Kudos to Andrew Troy and Matt!"

"Excellent work! 2.5 hours start to finish, replaced poly line with copper, trench was filled back in and I barely notice that it was dug (sod put back and all). Foundation was sealed back up perfectly. Really friendly, courteous, and knowledgeable technicians. Thank you DPP!!!"

"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."

"Had an underground yard drain installed to control standing water. Work was done quickly and neatly, and the drain is working exactly as expected. Great work!"

"I reached out on Anji for recommendations for plumbers and DPP called within minutes Ron Guderjahn came out to fix a slow drain for us. He explained everything, gave us several options on how he could do the repair with different price points, and was extremely nice."

"I had a slow draining kitchen drain. The plumber reamed it out as best he could, and it worked fine after that."

"We initially retained Martin to redo the kitchen, and we chose him because of price, flexibility and lack of hassle. Martin did all the carpentry work for the kitchen remodel, including plumbing the walls and fixing a termite-damaged floor beam, and he also did all the plumbing work. Work was done very well. Because of the good work, we then asked Martin to remodel a bathroom, and that was done very well, and included tile installation, new piping etc. That went very well. The prior work held out, and so we asked Martin to replace the roof. That roof work was done very well also. On the first day, Martin had about 10 people working on the shingle-part of the roof work to make sure that work was done before rains came. A following day his people did the flat part of the roof. We have now had some heavy rains, and I checked and everything is fine. No damage to the guttering system. So, very happy and would recommend."
