What People in New Jersey Are Saying

We have only had an incredible experience with RAdata! We always have had a pleasant experience working with RAdata. Their staff are friendly, knowledgeable and always willing to go above and beyond. We recently needed a water treatment device installed, our technician was Ted. He worked within the parameters he needed to, but ensured to go above and beyond by completing some extra work so we didn't need to be charged a bit more to install another piece of equipment. We appreciated Ted doing a bit more work to save us money. Ted kept the area cleaned and left it as he found it. We also were very impressed with the quick turnaround and updates we received. We were within a tight window, and RAdata was transparent with what they could do and they delivered. We strongly recommend RAdata for any well water needs - treatments, testing, etc.! Thank you so much for the great service over the years!

A big shout out to Charif Simmons for the outstanding Job he did with my Radon mitigation system. He identified problems that I was unaware of and provided quick solutions to same. There is an old saying that you get what you pay for. You can't put a price on professional, knowledgeable and courteous service. I recommend RAdata to everyone and when you do call request Charif.

They are expensive and do not explain the results of your water test unless you ask for one. I don't understand why they do that. BUT all that said, they respond and show up within a few days of calling. Results come back fast as well, but like I said, the person that sends the results does not explain what your results mean. Once someone does call or email you with an explanation, they are very nice and easy to talk to. They go over everything in great detail and explain treatment options if needed.

Today, Rocco Dimichino installed the electric outlet, wires and switch for my Radon fan. Rocco did an outstanding job of customizing the pic run from the garage to the outside of the house. It is super professional and is NOT an eye sore. He was very clean and kept the drilling into the house external to a minimum. What a great job he did. Thank you very much Rocco!!! You are a true professional skilled electrician! God bless!

Ours is a not for profit outreach program. We are part of Episcopal Church of S. Luke and St. Mary. Our Haven is a rural cottage in Warren County. Our guests are children (and their family) who have a life-threatening illness and/or are on the Autism Spectrum. They enjoy a 5 day vacation out here and at zero cost to them.Because of the child’s condition and treatment, their personal immune systems are compromised, at best.RAdata have been servicing our well-water treatment system for over 10 years. Given the health fragility of of our guest ‘kids’, we have total trust and confidence in RAdata and their skilled technicians. Today, as usual, Dan was prompt, professional and patient in explaining options and recommendations for our system. He was a pleasure to talk with and RAdata are an important resource to Haven of Hope for Kids.Our sincere thanks. JohnPresident, Board of Trustees for HoHfK

Six months ago we had RAData install a radan gas mitigation system plus a water treatment system. Today their technician, Drew Lovasi, came to do routine maintenance on the water treatment system. In addition, he also brought and took down into our basement the twenty bags of salt we had ordered for the next several months. Drew, we appreciated all those trips you made up and down the steps for us and then proceeded to check over the system…all the while answering our questions. It is a pleasure working with RAData.

I had RAdata check my radon mitigation system to address an increase in levels observed during colder weather. Office staff were friendly and responsive in answering my questions. Derek was the technician that inspected the existing system’s condition including a check on the vacuum achieved under the slab. Derek was friendly and helpful in answering my questions and explaining his work. We discussed several options for improving the suction under the slab by adding another suction point tied into the existing system. I chose one of the options and Derek went about his work quickly and efficiently, cleaned up the work area, and retested the suction under the slab showing improvement in air flow due to the added suction point. In my opinion, working with RAdata was a comfortable experience and I would recommend them to anyone needing radon mitigation services.

We hired RA Data to install a water softener at my home. From start to finish, RA Data accommodated my schedule and needs, got the job done, and made sure I was comfortable with what was happening, how it was happening, and what to expect when it was done.My experience started with Dan, who heard my needs, worked up quotes for me, and didn't get annoyed when I inevitably had to call back a couple times with questions. Awesome. They were able to schedule me 2 weeks out (which in my experience is super quick given how booked contractors are).The day of, Ted, our tech, arrives and walks me through the whole project, involves me in making decisions about placement and installation of the equipment, and stopped to see if I had questions before and after the work was completed. He was courteous of being in my home, was careful not to let our pet out, and cleaned up the work area perfectly before bringing me down to review the work.There were no surprise fees, upcharges, or excuses as to why something couldn't get done halfway into the job. I paid the price that was communicated to me upfront and now my water is soft and I am happy.I recommend these guys for both water treatment and radon mitigation. Just keep in mind that at the end of the day, the techs are contractors and for service calls, charge hourly. If time / cost is an issue, communicate it upfront so your expectations are set before work begins.
