"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"

"We found Basement Waterproofing Nationwide to be highly ethical and very knowledgeable. A little over a year ago we had BWN perform some basement waterproofing. We were delighted with the work and the options presented to us as well as the speed with which it was done. This summer during the very heavy rains, we had some water seep into the basement so we called for an evaluation. As it turned out, the rebuild contractors (which we had opted to contract with a lower price provider vs. using subs hired by BWN) never communicated to us that the newly installed sump pump required an electrician and that it was not hooked up. This house is inhabited by tenants and we are not in the same state, so it's hard to tell where the communication breakdown occurred. Basement Waterproofing Nationwide's service rep however was extremely professional and helpful in delivering this bad news. He also checked and was able to confirm that the waterproofing was still good. He made a few suggestions like letting us know that he noticed where the drywall had been replaced that the outlet plates were never reinstalled. I also had some questions about the contract and he was very helpful and had the office fax me the pertinent info that same day. Lesson learned for me was that it would probably have been better to let BWN hire the contractors for the rebuild esp when you are out of town and unable to oversee. When there are heavy rains in the area like Baltimore had in July, it might take a few days for them to process the volume of calls especially if the nature of your request is minor. But they do respond. They are extremely professional and they stand behind their work."

"Our foundation was seriously compromised due to water intrusion. Steve responded quickly and gave us an estimate at a great price. He was knowledgeable and informative. Dan and his team repaired our foundation, installed a drainage system and pump, as well as a vapor barrier. Our basement has been dry and free of mold since. The project was completed in a matter of days. I couldn’t believe how quickly they worked. I recommend the gurus to everyone who needs basement repairs. Thank you again!!!"

"I had a great experience with Best Buy waterproofing. I contacted them for inspection due to water rising underneath my tile in the basement. They responded very quickly and had someone out for the inspection a day later. Ed completed my inspection and was very informative and communicative throughout the whole process. He didnâ t try to scare me into getting any services and was very patient with me. Any questions I had he was on it and available. When I made my final decision it was quick and a painless process. The crew cleaned up well and walked me through the work they had done. They installed a new drain and sump pump. Might I add they made my installation very esthetic by placing the line in the wall to hide the pipes when the dry wall is replaced. I will definitely recommend to friends and family!"

"They installed our sump pump system with backup battering very efficiently and professional and in less than one day. After discussions on the correct equipment, they provided additional effort to be sure the wi-fi backup equipment was installed and was working efficiently. Any questions on installation and operation I had were answered on-the-spot and with ease. System seems great and I now have peace of mind during a bad storm or if the power should go out. I would recommend them to anyone."

"We are very pleased with the excellent results of the installation of the custom-built Grate Drain™ basement drainage system by Floodbusters. The entire team at Floodbusters is courteous, professional, and responsive. We had many concerns and apprehensions about this project because it had to be done in a finished basement area. Mark, who first surveyed the situation, carefully inspected the area and was able to determine the exact location and extent of the drainage and pump system required to limit any unnecessary demolition. He also took the time to answer our many questions and provided material specs and video so that I knew exactly what this project entailed. Craig was able to schedule our project within our timeframe of availability and stuck to it! Charles and Dwayne arrived as scheduled and worked steadily and efficiently. Even the boss came on site to give a hand hauling debris. The team took care to protect and clean surrounding surfaces as they worked. The project was completed on time as promised. We highly recommend Floodbusters for any of your basement waterproofing needs. Their responsiveness, timeliness, and attention to detail in workmanship will give you the confidence in a company that is reliable, trustworthy, and true to its mission in producing a high quality of service."

"I moved into my house about two years ago and would get floods in my basement during every storm. I tried to fix it myself environmentally, but failed in my attempts. I then decided to finally fix the problem and get my basement waterproofed. Being relatively new to Delaware, I put in a request to get free estimates. I had a few companies come out to look at it and narrowed my choices down. I was down to Basement Waterproofing Specialists (BWS) and Basement Gurus. The difference was the representative from Basement Gurus had a more natural approach and took the time to ask numerous questions, as the other representatives asked little to no questions. The Basement Gurus representative suggested to fix internally AND externally, plus they even added a lateral system in my basement. No other company felt to even thought of a lateral systems or external drainage, or to even ask about it. I could not speak more highly of the representative and his team at Basement Gurus, they took the time to explain every step and the process before and during the installation to keep me involved with what was going on. The crew was extremely polite and respectful of my house, they were very efficient and they "did not play games" for lack of a better word. lol The very next day we had heavy rains, which I was excited to test out my waterproofing system! During and after it rained there was not even a single drop of water in my basement or laundry room. The representative even had his team remove and replace all of the studs that had become moldy and also put in new mold resistant drywall. Basement Gurus treated us as if we were family and for anyone looking to get waterproofing done in their house, call Basement Gurus, they truly stand themselves apart from the competition!"
