"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!!!!!!!!"

"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 had a fantastic experience with Dan from Basement Gurus! He helped install a French drain in my basement crawl space, and I couldnâ  t be happier with the results. Not only did he address the drainage issue, but he also sealed off openings under my wood deck that were allowing raccoons to get in. Dan was professional, knowledgeable, and kept me informed throughout the process. Highly recommend Basement Gurus for any basement needs!"

"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."

"This company did a first class job solving a basement foundation water infiltration problem in our commercial office building in Upper Bucks County, PA. A project manager came out to assess our situation; he came up with a proposed solution on the spot, provided us with a written proposal and sample photos of other similar work they had done. The work required excavating a small portion of the foundation on the exterior and filling a crack in the foundation wall down to the footers. The crew came out as scheduled and completed the job in a single day as predicted. Some follow up tweaks were needed, and I'm happy to say that the customer service team and follow up crew responded promptly and made some necessary adjustments to button up the job as promised. This is a first class operation and I do not hesitate to recommend this outfit to other colleagues and property owners needing this service."

"PRO: For installing an interior French drain, while it was pouring outside, the crew was extremely clean. Both my yard and interior of my house was left with only minor evidence of the work. PRO: The initial consultation with Phil Thistle was informative and provided me with piece of mind in terms of the project and projected outcome. It seemed as though we would have support throughout the project. PRO: Owen Dan Kelly is very dedicated to the quality of his company and the work they do. Once he found out about some of the concerns I had with the project, he remedied them immediately. I was very impressed with the attention he provides his customers. CON: Communication. Up to the install, I was in constant contact with the company about timing and expectations. However, as soon as the install began and then directly after, I was on my own. There seemed to be no one overseeing the install, just the crew doing the work. Also, there were miscommunications about the project throughout the install; the crew was asking me for direction on installation steps I have no background on. CON: Support. Again, as soon as the install was complete, that was it. Phil showed me images of pictures he took with satisfied customers on past installs, making me feel that he was dedicated to the project's success. However, after the consultation, even though he was copied on various emails about some of my concerns, he never got back in touch. In addition, no one ever contacted me to see if I had questions about the finished product, to see how everything turned out, or if there was anything else I needed. CON: Timing. The crew was on-time for the install both days, however, the schedule was more impactful to my routine than expected. The crew worked 9AM - 3PM only on Day 1. However, to finish in 2 days, they worked 8:30AM - 7:30PM on Day 2. As I have a small child, having construction still happening after 7:30PM was difficult, but more so was confusing as Day 1 ended so early."

"Nick and team were extremely helpful, informative, responsive and did exactly what they said they were going to do (and even better when they said they were going to do it). Nick was very reachable via email and was more than willing to help. I hope to never need a foundation expert again, but if I do I know that I would definitely have them do the work."
