Had to have my radon system serviced after 3 years and fan replaced. Fan was under warranty thankfully. Ryan was my technician. Very courteous, knowledgeable and efficient. Worked in this terrible cold to quickly replace the fan outside and also the batteries inside. Left a radon kit to recheck in 24 hours. Very happy with service and company

We use them for our yearly Maintnence and water testing as well as replacing tanks as needed. It’s easy to get an appointment and I love they tell you when the tech is on the way via text. John is great - hope they send him every year. My only suggestion would be to respond to emails after test results come in, had to call to get an answer.

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.
