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

"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."

"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."

"As someone who has dreaded going to the basement for 20 years, I am now incredibly thrilled with how dry and clean the space has become thanks to the excellent work by Gary, Benjamin, and Edgar at Basement Systems USA in Elkton, MD. These men were polite, respectful of everyone's time, left the place cleaner than they found it, and were thorough! Each step was carefully explained to me and confirmed throughout the process. There are no more ugly, mold-stained walls or beams; water runoff outside the house was diverted; and a new, size-appropriate sump pump and dehumidifier were successfully installed. I couldn't be more pleased with the professionalism of this team (and they finished sooner than quoted)! Thank you Basement Systems USA and especially to Gary, Benjamin, and Edgar!"

"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! "

"They came out & explained how they were going to resolve the drainage issue from our basement & lawn. We were surprised at the depth of work they had done to ensure that this issue was resolved for the new owners. They did as they said they would do per the estimate. These guys worked so hard & got rained on a good bit of the day, yet that didn't stop them from completing the job. They went above & beyond. It has been over a month now & we are very pleased to see no drainage issues. Thanks Waterproofing One for coming to our rescue! Dave & Lisa"

"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!"

"BQ Basement has a unique foam based leveling product (not mud or concrete) that is guaranteed. They did a great job leveling a very crooked (sinkhole) slab and re-graded a series of slabs by my foundation to get the rain to flow away from the basement. Nicely sealed the seam at the foundation too. Thanks!"

"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"
