    Just Dry Basement

    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!

    Highly recommend this company! I had confidence in this company when I made the first phone call…read moreand could actually talk to a real person and not hear the "this call will be monitored for quality assurance purposes". Elliott the owner came within a few days of me calling and gave an estimate to repair a floor joist that was severely damaged by a plumber. They came and completed the work just a couple days after that. They did a great job and even reinforced some other surrounding joists while they were there. If I ever have any foundation or basement issues in the future I will not hesitate to contact them to help!

    Sad to say that I cannot recommend this company. We had someone visit our home for an estimate on…read morecrawl space waterproofing a week ago. There were many signs showing that this company is disorganized and unprofessional. One or two I could ignore, but not all of this....for instance: i explained in detail everything on the phone when making the appointment (multiple things outside and inside I wanted to have looked at) and yet the inspector that showed up didn't have any knowledge of anything -- he didn't even know if he was inspecting a crawl space or a basement. clear lack of communication within their team.; the inspector didn't bring his own flashlight and had to borrow ours. all he had was his flashlight on his personal phone. kind of odd.; 3 options/quotes were discussed at the time of the appointment but only one quote was sent to us; when following up via email for the additional info, it was never responded to; a text was sent from the company to me to follow up and i reminded them i was still waiting on the response to my email with the options i discussed with the inspector; couple days later they texted me again asking if i had made a decision, to which i responded they had never sent me the quotes discussed.; they texted me a link to a quote, (so in total, i only ever got 2 of the 3 options discussed), and the quotes are unnecessarily confusing. they don't look like your typical quote, things are itemized as all $0, all the services they offer are listed on the quote even if you're not getting them, it's just strange. the inspector at our initial appointment did seem knowledgable so we were going to overlook the miscommunication/unprofessional flashlight thing. it wasn't a big deal really. but, how everything was handled after our appointment was very strange which makes us uneasy about trusting them with this project. also, there was never any apology for the missing quotes or the miscommunication at all. a simple "sorry about that, we'll send those quotes over shortly" would go a long way. All this to say that with all of this combined, I could not move forward and would not recommend this company.

    Up on the Roof Chimney Sweep - Chase cover replacement

    After having roof work done by a roof contractor I discovered a leak in my ceiling by the chimney…read morechase where it penetrates up and out the roof. Calling back the original roof contractor and informing them of the leak they said I needed to replace the siding of the house in the area of the chimney chase at the tune of $4000!! I then began calling other various contractors for this repair and was told all kinds of BS, from having to rebuild the chimney chase, having to wait as they were too busy, too cold (it was December) and told to wait until spring, etc. It was a bad leak and causing damage to my home not to mention the stress caused on me being at the mercy of contractors. So... I kept on searching contractors and came across Up On The Roof Chimney Sweep during I'm sure their busiest time of the year like everyone else's. However Up On The Roof Chimney Sweep promptly returned my call, took my information, promptly came to measure the chimney chase and came back with a reasonable price and did not take advantage of my situation! I scheduled the job with Up On The Roof Chimney Sweep and could not be happier with the quick prompt service and results that were received! It has been a full 2 months with some heavy gusty rains and no leak so this job was given the test of time! There is barely any worse feeling than being at the mercy of contractors when you have a situation that needs to be correctly fixed in a timely matter and not at a contractor's convenience. Up On The Roof Chimney Sweep not only fixed my chimney leak but relieved the awful stress on me from the start with their integrity, price, answering all my questions, and all the way to the finish product which looks great too! I highly recommend Up On The Roof Chimney Sweep and will definitely use again!!

    Yes, very good guy. He did an excellent job with my fireplace. Resonable prices also.read more

On the follow-up to our first project with Mike and his team at Select Basement Waterproofing, we proceeded with the plan of waterproofing the basement and keeping moisture contained at a reasonable level. Mike and team installed the following in our 160+ square foot basement: -French drain -waterproofing / Insulation on walls -new sump crock (with new battery backup sump pump) -Glass block windows -Radon pump -cementing / closing up the floor I was thrilled with the results of the hard effort given by the team. Everything was completed thoroughly, professionally, and cleanly. No questions were left on my mind (kudos to Mark for that level of detail and for managing my questions). Mike and team were professional, funny, friendly - just good people all around. I even took them to lunch a few times during the project! Mike gives an honest assessment and I never got a feeling I was being oversold. He and his team bring hard work and years of experience. Highly recommended with zero hesitation.

He was so honest and he assessed that the water looked like it was a burst pipe and not ground water (I had 4 other waterproofing "experts" that just wanted to sell me their systems!). What an honest person, and his estimate was much lower than the other estimates I received! I would highly recommend Select Waterproofing for your groundwater problems :)
