"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!!!!!!!!"

"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!"

"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!"

"Explained the fix and performed when they said they would and excellent job"

"Very well done. Took precision measurements. Made sure the work area was kept as clean as possible given the dust produced by grinding the granite. Very pleased!"

"My wife and I purchased our home in June in a flood zone. There was hydrostatic pressure causing foundation wall bowing. There was a sump pit and some sort of drainage system, but that thing cycled constantly day and night. The deluge of rain last month caused water to start coming up through the basement floor flooding the finished basement. The existing drain system failed. I immediately began researching reputable waterproofing companies to come out, diagnose the problem and provide a cure. The very next day I heard back from Basement Gurus. I was informed that with the influx of calls due to the local area flooding the owner of the company himself would come out that weekend to assess the issue. Dan arrived on time and got right to work inspecting the problem in the basement. He brought my wife and I upstairs and took time to explain the problem and a proposed solution. It was self-evident that the product he would be installing was quality, that they really were going to literally get to the root of the problem by digging down the foundations footer. The scope of the work described was clear: they weren't afraid to work hard and they weren't cutting any corners. He wrote up a quote within our price range and what my research indicated was more than reasonable. He felt so confident in his proposed solution and teams ability to solve the problem that he offered a lifetime transferable guarantee we would never have this problem again which was included on the contract. We felt so comfortable with the proposal that we locked in on the spot. His team arranged to come out as soon as possible and they arrived about 8 am the day of the project with about 15 guys. Wow! This guy means business. For us, this meant a great likelihood that the extensive project wouldn't drag on (unlike this review). They worked all day and were done and cleaned up by about 5. Since the job was finished the sump went from cycling every 57 seconds day and night, to cycling just once a day, 10 days later. I can finally sleep at night without hearing the water hammer from the sump pump constantly. With how often the sump was cycling I couldn't even find enough time to swap out the check valve for a quiet one. I am planning on fixing that this weekend! So far we are more than impressed. I feel confident that this problem is solved for good, and if anything goes wrong I trust that Dan and his team will make it right. This guy oozes passion for what he does and it is very clear he actually cares about the people he is serving. He is clearly knowledgeable, his team is equally extraordinary. If you have any waterproofing needs, do yourself a favor and let this guy come out to propose a solution for you. If our experience is any indication I feel confident to say that you won't regret it. If you are asking why you should trust a stranger know that I received nothing in exchange for writing this review. I am just a grateful home owner who understands how stressful a water emergency in the basement can be. If I can help one person find the same relief that we have experienced than it was well worth the hour it took for me to write this. Thanks Dan et al!"

"Excellent, hard working forman and crew who knew what they were doing. Foundation repair and installation of sump pit. pump and backup pump was completed in two days, as promised. Highly recommend."

"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."
