    Tight space apparently a non issue
    Sean F.

    Had AJ install a French drain and sump pump on our early 40's home. He and his squad did an outstanding job. Moved all of our crap out of the way for us. Did not cut ONE corner in doing the job. Others wanted to run the drain in front of our oil tank because it was be easier for them. He did it the right way, which was far more difficult. Very easy to get a hold of, quick to respond, and clearly knows how to do the job properly. Much easier to trust a company who is locally owned, has their name attached to the business, and a ton of local references.

    Found mold in my basement, thankfully I call A J Waterproofing

    Really had no idea what I needed. Vinny fully explained what needed to be done. Felt like a little…read moremore than I expected, but seemed it would rectify the problem. The job actually got done a little faster than they thought they needed. Problem solved.

    can't say enough good things about my experience with JustDryBasement. From the very first phone…read morecall, everything was top-notch. I had contacted several companies before, and honestly, most made me feel like I was bothering them. But when I called JustDryBasement, Susan answered--and she was incredibly professional, kind, and helpful. That first impression already set them apart. She connected me with the owner, Elliot, who has been amazing from start to finish. We worked together on three separate projects, and in every one, his quality of work and professionalism truly stood out. First project: Elliot installed a French drain in my basement and noticed damage to the walls, so he recommended and installed a special polyester wall barrier. He walked me through the entire process with patience and clarity. I waited a full year before writing this review, just to make sure everything held up--and I can confidently say, even through heavy rains here in Medford, NJ, my basement has remained dry. His work speaks for itself: solid, clean, and reliable. Second project: I still had high humidity in the basement, so Elliot suggested and installed a whole-house dehumidifier (AprilAire E100). He connected it directly to the French drain system, so I no longer have to worry about emptying water or dealing with moisture. It runs efficiently and quietly--even when I'm traveling, I have peace of mind. Third issue: Recently, I had water flooding in the finished part of my basement. I thought it was the water heater, but Elliot offered to stop by just to help figure it out. And he did--within two days, exactly as he promised. He quickly diagnosed the issue: it was actually the AC pump, not the water heater. Thanks to his advice, I was able to get the original installer (under warranty) to fix the problem. Elliot didn't have to help with that, but he did anyway--because that's the kind of person he is. Beyond his technical skills, Elliot is honest, communicative, punctual, and just a genuinely good person. He always followed through on his word, showed up on time, and took the time to explain everything clearly. Even when I had concerns, he didn't brush them off--instead of just talking over the phone, he came in person to give me peace of mind. I also want to give a shoutout to his partner Phillip, who was also fantastic to work with, and again, to Susan, for being so welcoming and helpful from the start. After working with this company three times, I can honestly say: I highly recommend JustDryBasement to anyone looking for quality, professionalism, and peace of mind. Their prices are more than fair for the level of service they deliver. It's rare to find people in this field who truly care--and I'm so glad I found them. Thank you, Elliot and team!

    I have not used this company, however I am making a review to say that I did drive behind a toyota…read morepick up truck (I don't know cars)? That had a Main Line Waterproofing large sticker on it. This car drove quite recklessly throughout Montgomery ave. They tailed me, cut off a car, and then proceeded to cut me off too. Montgomery is known to be a busy street with lots of road work in the morning, so you should plan ahead to leave earlier rather than put everyone on the road in danger because you're late or maybe just because you're impatient. I have no way of knowing if that person works for the business or just supports the business, but either way it should be known that it's not a great idea to promote a business on the same car that you use to aggressively cut people off.

    Our new construction home was facing water issues leaving my husband and I in a panic. I called…read moreMainline Waterproofing to discuss the problem and James came to meet with us the next day! James at Mainline Waterproofing was absolutely fantastic to work with. Extremely communicative (responded in real time to me on text and emails), quick scheduling, knowledgeable and professional. I felt so confident they would do the work correctly. We weighed the pros and cons of several options and they didn't pressure us into doing more than needed. Ultimately we put in a second pump/pit and window well drains. James also introduced us to a general contractor he knew (who has also been fantastic/communicative/speedy!). They coordinated on the work, visiting the job site together, making us even more confident. My biggest thanks to James, Herb, and the rest of the crew.

Both times they weren't able to assist for 2-5 weeks. They also said that they only can assist during business hours. The system is not just going to have issues during business hours! Not what you want in an emergency. Since they went bankrupt in 2016 and re-organized, they pulled out of New England, leaving all of their customers with no options in an emergency. They also raised their service charge to come out and replace the pump from $185 to $370 during that time. I asked why and Crystal told me that it was due to the economy. I am in Finance and doubling your price for a service makes no sense to me in a one year period and attributing it to the economy. The President also does not take calls and does not have an office and travels in his car 100% of the time according to Crystal as well. I have since had to hire another local company in my area, as I am sure many others in the New England Region did during the past 2 years.
