“Thank you so much for the great service! The guys were very friendly and professional and all and all your whole team is outstanding!

Also thank you for the $50 back and honoring the quoted price. I will certainly tell others what a great experience I had working with you.”

~ Jock Holsworth

“I’m very happy with the results and am glad we got in touch with professionals like you.”

~ Erin

“Just wanted to pass along feedback regarding our installation on Dec. 23rd. Terry did an excellent job! He was always very careful in using shoe covers when going in and out of the condo and was able to deal with a tight basement ceiling situation. He also took the time throughout the process to explain what he was doing. He even called our initial estimator to discuss the proper motor for our situation (leading to a $100 reduction in cost). It was definitely a challenge working outside that day due to downpours. He was very professional and persevered through it all. When we explained we’d like the exterior pipe to go right along side the downspout, he did so beautifully. He didn’t even disturb the bird’s nest right under the eave. Terry did an awesome job. He’s a great asset to your company.”

~ Vicky Esgar

“Brandon is very thorough and methodical yet very efficient and a smooth technician and good communicator. I’m confident with the plan and the wait for a 90 day test and have set up the Acculab test. Thank you for your coordination and collaboration.”

“Just a brief note on your installer and the job he did, as I was there during the entire install and know that can be a little unnerving having been in the construction field myself. You are lucky to have him very professional efficient and meticulous, in his work. He did a super job and Chris the electrician did a nice job also and they work very well together. You should know they are both great ambassadors for your company. Please let them both know we appreciate the fine job they did. Its easy for people to complain but its nice every once and a while to get a big Ata-Boy!!”

~ Tim & Deb Sweeney

“David, Brandon did a great job and was very pleasant. You have a very good employee!”

~ Jim Klinzing

“You have a great crew that took care my homes problems.  They were fast, communicated what was going to be done and how it worked and cleaned up after themselves! Great Job!! Thanks again.”

~ Dennis Peach

“David, thank you again for your excellent work and team. It was nice to meet your son when he worked here at the house. Just a quick update. Since the day the guys added the 3rd suction point, the levels have been between 2.3 and 2.6. This has never happened before and (competitor)’s mess was mostly to blame. I appreciate your wisdom to go with the third suction point. It has certainly done the trick. I don’t know how often other customers write back to thank you for your work, but here’s a BIG THANK YOU from me to you and the guys who worked here! May God bless you, friend!”

~ Rev. Dr. David Ambroso

“Dear Dave and Chris! I can’t thank you enough for taking the time out of your extremely busy days to try to help me take care of my family, and figure out what kind of Radon situation I was being faced with! I don’t even live in WI, and there is no way for me to hire you guys, but nonetheless, that did NOT deter you from sharing your expertise with me, so I could make an enlightened decision as to how to fix my Radon system. My wife and I just had our first child, and this Radon “stuff” is totally new to us. We have gotten 4 different stories from 4 different companies where we live, and so I searched the internet for a reputable company…across the country!!! Sure enough, with a tip from a good friend in WI, and from reading some blogs online, I found you guys…and thank God I did! When I read your words Dave, about how this is how you have supported your family and so you treat each customer with utmost reverence, bearing the thoughts of taking care of your own family, in mind…I knew I was in good hands! And after 2 great phone conversations, one with Chris and one with Dave (the owner!), and an email full of pictures that you guys looked at and assessed for me…I got more answers from you than I did from ANY of the other companies we have dealt with! From the bottom of my heart, you have my sincere respect and appreciation! I know I can count on you in the future, if need be! God bless you both and your families and your company! I would recommend you to anyone on this planet!!”

~ John P

“Dear Dave: I received and copied your attachments regarding our recent successful Radon test results for our closing next week. One big item checked off the list! Thank you for your team’s courteous, professional, quick and thorough work in all aspects. It has been a pleasure doing business with you. If you wish to use my complimentary comments on your company’s web site, you have my permission.”

~ Charles H. Smith III, Elm Grove

“David, I wanted to send along a hearty compliment to you and your company for employing two fine young men such as Nick and Zach. They called saying when they would arrive and when they did my wife was duly impressed with their manner , professionalism and their appearance. I was unable to get there until they were wrapping up the job. Having been a High School science teacher for 38 years, I worked with thousands of young people. These two are keepers! The represent everything you want your company to be. Nick is extremely knowledgeable in what he is doing and able to answer all of a former science teachers questions in a competent and professional manner. Zach is eager to learn and for the moment takes his lead from Nick. I doubt that you could find two other young persons to represent your company better. I sincerely believe that there is a bright future ahead of them in your organization and they will rise to what ever challenges that you put them to. Casual discussion lead Nick and I to realize that we both knew a former colleague of mine that taught in Neenah; another great connection. I would have enjoyed the opportunity to work with both of these young men in my classes. With representatives such as Nick and Zach your company will go far.”

~ Paul De Chant

“Great Job! We are very happy with the outcome of your installation and results. The job was done on Darboy Drive in Appleton. I wish we had hired you long before! In addition to very high radon levels, we had been experiencing high moisture levels in the house. We had done several tests with hardware store pods ourselves, and even purchased an electronic Safety Siren Pro Radon Meter, and found levels as high as 16.0 (pCi/L) before we hired you; we had tried to lower the levels ourselves, with little success and much expense. Your initial tests confirmed levels 3 times higher than the EPA action level. After your installation, the excessive moisture in our house became normal, and the radon level from your pod AccuStar test was an amazing 1.1 (pCi/L), and our electronic measurement device reading was 1.6 pCi/L, based on a longer test time frame with much higher starting levels, which probably pulled its average up a little. It had been calibrated in December 2013. The installation through the garage is virtually invisible, and we can’t hear any sound of the system entering our house. The cost of the installation was much lower than I had anticipated.”

~ Guy Bull

“We recently visited Mr. Abroso’s house and discovered a poor quality system install by another company that was not lowering his Radon levels. We dismantled the existing system and installed a new one from scratch. His letter follows. I wanted to express my sincerest thanks and gratitude to you all at Radon Specialists. David, thank you for your support and concern and help. Chris and the guys did a great job today. We found many problems with the (another companies) installation including wiring issues, screws into the piping that were leaking, hold-down screws that were wrongly drilled into the siding, overuse of 90 degree bends in the piping, and the worthless fan. The fan wasn’t even UL listed! It was Canadian. It was hardly blowing anything at the top of the pipe! I can’t wait to see what your changes bring. My Radon alarm has been going off for 3 months while (another company) played with the problem, all the while the levels were between 50 % and 75% above government guidelines. Your professional and courteous team did a great job. I’ll be letting you know the numbers in the next weeks. I consider you all a true God-sent bit of hope. In point of fact, I may even owe you the lives of my family! As someone who has helped many needy families through working with Habitat for Humanity, I need you help, and you came through beautifully. Thanks, friends at Radon Specialists. Thanks Dave.”

~ Dave Ambroso

“Hi Dave: Two sets of tests confirm that you guys do good work. Alpha Energy Labs(Outagamie County kit) 8/16/13: 0.8 AccuStar Labs 97 day test: 0.7.”

~ Ed Sabish

“David Shane did our radon system install on July 19th. I want to compliment Shane on the install. He was very professional and accommodating. He did a great job and we are very happy with the system.”

~ Dave Mercer

“David, I could not be happier with you or your installation staff. I just checked the meter that Chris left and it reads .09. My wife will be stopping Monday to return the meter.”

~ Dave Pettit

“Dave, Thanks again for all your great help and the many times you have come to our rescue with the installation of the Radon system. Tell Nick & Chris thanks for all their help with the installation. You sure have very nice guys working for you! They too answered any questions that we had and knew what they were doing. Keep up your great work and your big smiles.”

~ Bonnie & Dennis Feldkamp

“I would like to compliment you on your staff from the quote to the install. Both gentleman were friendly and professional. Shane also caulked the sump pipe outside on my request. Little things make a difference. He also pointed out my sump pump was shot. Tell Shane I put a new one in today and thanks for the tip on cleaning the PVC pipe before I painted, it worked great. I’m sure you get complaints all the time, well this time nothing but Kudos to you and your staff. I will definitely recommend you to anybody interested in your services.”

~ Dan Hebel

“David, thank you so much for the great work your guys did. We just got our 90 day test back today. It was 0.7. Prior to putting in the system, I think we were at almost a full 7.0. “Amazing! My family feels much safer now. Thanks again.”

~ Derek Haroldson

“You installed our radon mitigation system on 2/16/12. We had readings of 13.3 and 10.3 in our basement prior to the installation. I did a short-term test again after the installation, and got the results back from Alpha Energy Laboratories in Texas yesterday (3/14/12). The reading is now “less than 0.6.” “Thank you for your wonderful service. We are very pleased. We have the long term test in the basement now, and will send it in when the 90 days are up.”

~ Ronald W. Leeman

“Thanks David. I’m extremely happy with the system and the guys, and hopefully all will be well for years to come. Feel free to put me down for a positive reference!”

~ Derek Haroldson

“It is with great pleasure that we write this complimentary note to you. “On March 17, 2010 your Company Representative, Shane, installed a Radon Mitigation System at our home in Mountain, WI. Shane has a very pleasant personality and was polite, professional, respectful, worked efficiently and quietly and cleaned up as he went along, rather than waiting to the end of the project. Shane was a pleasure to have in our home and if he were in our employ, we would consider him a valued employee. “In the mail on Friday of this past week, we received our 48 hour, short term Radon Test results….. .6!!! Last year our test result was 13 and my husband patched some wall cracks in the basement. This year our test result was l9.7 before we contacted you. “We will recommend Radon Specialists of Wisconsin, Inc. to others in this area as the conversation of Radon surfaces. God’s Blessings to you as you continue to provide quality service to customers in your business.”

~ Thank you, Marliss-Ann and Ned O. Lundquist

“I just wanted to drop you a note to tell you how pleased I was with the work your two employees did at my residence yesterday. Shane and Nick were very professional, courteous, and knowledgeable. Being a High School Tech Ed teacher that teaches construction everyday, I know the difference between high quality work and sub-par work. This was without a doubt very high quality work. Overall, I’m very impressed with your company and workers. I will make sure to pass along your company’s name to anybody in our area that might have radon issues. Thanks again!”

~ Kevin Hein Woods/Construction Technology & Engineering Education Kewaskum High School

“Hi David, I wanted to extend a sincere thank you for helping our family through the radon mitigation process. We live in Leroy and you made the exception to travel a little further than your business normally extends to distance wise. Both our conversations and your business website has been a wealth of valuable information. You have been prompt, professional and your down to earth manner has made the entire process so much easier. The fact that you are a Christian certainly also means a lot to us as well. Your service technician was very courteous, polite and knowledgeable. We have young children at home and appreciate your expertise especially when it comes to an issue of safety in our home. We are so pleased that we have reduced our radon levels from an average of 14.8 pCi/L down to 1 pCi/L based on our short term test comparison prior to and after the mitigation system was placed. We plan on letting our family and friends in and out of state know about our experience with radon and hope they too can become informed about such an important issue. Thanks again!”

~ Tara and Greg Tibbe

“I want to tell you that the Radon mitigation system installation was done very professionally. I compliment Shane on his workmanship. Definitely a first-class installation.”

~ James Hopp

“Thank you for doing a nice job on my Radon Remediation system – the work was done very professionally and the area was cleaned up so that I didn’t even know anyone was there!”

~ Mark Stae

“Just dropping a note to say how pleased we are with our Radon system installation. Our basement smells like nothing! Kind of weird, as one goes into a basement and expects it to smell, well, like a basement. Now we smell absolutely nothing and it is much drier, as well. I am sure glad I went with the new sump pumps as they pump out much faster than my old rigid upright. S/P is holding just under 1.0 WC so all is well. “The young man doing the installation was very good, knowledgeable and kind. You should be proud of him.”

~ Peter D. Honer

“Just wanted to let you know how pleased my wife and I were with Chris and Shane installing the radon device in our home. They were very professional, courteous, answered all my questions, and were very friendly. Not to mention how clean and organized the device was installed. I think they represent your business very well.”

~ Ben and Kim Treml

“Your employee, Shane Van Linn, did a radon mitigation system install at our house today. He arrived on time, got right to work, and did a professional job. He was neat and orderly, and cleaned up after himself as he went along. It was obvious his goal was to do the job to my satisfaction, which he most certainly did. “Shane was respectful and courteous at all times and was able to answer all of my questions. You are fortunate to have a young man of his caliber in your employ.”

~ Don Garvey, Waupaca

“I wanted to let you know how great of a job Chris and Shane did installing the Radon mitigation system in our house on Golf Dr. in Alaska, WI yesterday. They arrived on time and they were polite and professional. They got straight to work and they did an absolutely fantastic job. They also listened to my feedback and together I think we came up with a very good configuration. It really is a nice setup. I should take some pictures and send them to you. You might even want to use it in your photo gallery on your website. “I was also very impressed that they did not give up until they found that drain tile. Their installation was neat and clean and I could not be any happier with the job they did. Whatever you are paying them is not enough. Give those boys a raise. They were both very patient with any questions I had and Chris thoroughly explained everything to me from how the system works to the installation guidelines they have to follow. He also went over the invoice with me and made sure I understood everything. “Due to some problems with the electrical system in the house, I decided to wait and have my electrician setup the power for the system, but Chris and Shane tested the fan and the pump to ensure they were working properly. My electrician stopped by yesterday morning and met with Chris and Shane and they explained to him what was required. Also, it was too bad the ground was so hard because they were prevented from digging up the drain tile and installing the back-flow piece. But, at least Shane found the drain tile and I can dig it up when it is warmer and install the part myself. They both went over that with me and I understand what needs to be done. As soon as that is done, we will set up the home test kit they left with me. Thanks.”

~ Justin Temme

“We just wanted to drop you a note and express how pleased we are with the installer and the installation of our Radon System. I believe the installer’s name was Shane. He did a top notch job, was very professional and courteous, and the job was completed on time. Please feel free to use us as a reference if you would like.”

~ Randy & Lori Nichols

“Just letting you know I was very pleased with your company and the technician that installed the bathroom fan and radon mitigation system. The system looks great and I was impressed how they cleaned up everything. I would definitely recommend your company to others. Thanks!”

~ Joe Bertler

“The installation of our new Radon Mitigation system on July 12, 2007 was completed both professionally and efficiently by your two installers (Chris and Shane). They were both very helpful in answering my questions and concerns.”

~ Doug & Sandy Miller

“We were very curious about our radon levels after having the system installed in November, so we got another short term test from the Town of Menasha. We just received the results today (<0.3 pCi/L). I just can’t believe they’re so low! My husband will be surprised too when he hears the results. We’ve also noticed the moisture levels in our house are going down and the basement doesn’t smell anymore. Just wanted to let you know we are happy with our system and the work you did for us. Will contact you after the long term test you left for us if the levels are different, but I doubt they will be. Thanks again and Happy Holidays.”
