Get matched with top radon gas abatement pros in Apple Valley, MN

"I highly recommend A1 for radon mitigation! They did an excellent job and I was very satisfied with both the installation and the results. Andrew was very professional, knowledgeable, and extremely responsive in his communication. Andrew and Rob installed a drain tile depressurization system, which was vented thru the attached garage roof. The fan was located in the garage attic, which required electrical work by their sub-contractor Brothers Electric. The installation took about 2 hours, whereas the electrical work was completed the next day in about an hour. A1 provided a short-term radon test for post-mitigation testing. My basement radon level went from 4.7 to 0.6 pCi/L."

"Radon mitigation was not offered as a selection for service or project. please see email sent re: radon mitigation"

"Four man crew showed up and started with a review of work order and expectations (basement water drainage system)Quickly organized plan of work and promptly Started in a systematic way and accepted assistance from home owner. The crew was efficient and friendly. On the third day an additional crew of two men arrived to install Radon mitigation system. Electrical guy arrived to install outlet on outside of home and helped complete the radon system. Completed job quickly and cleaned up. Appreciated the review of planned work and customized it to our home. The crew leader listened and made appropriate adjustments. Thank you so much for all your hard work."

"I was very pleased with their work. The post-installation test results show that their system is removing the radon from my home. They got the work done promptly and were very easy to work with. And their pricing was lower than anyone else's. I highly recommend Radon Stoppers."

"Walt and his crew did an amazing job mitigating radon from our basement! Radon level went from 4.4 pCi/L to 0.3. Out of 3 bids, he was the only one to come to our house to look at how to route the system. He wasn't in a hurry and explained everything to me in layman's terms. On the day of the install, they arrived promptly and explained what they were going to do. They suggested testing out the sump pump before they sealed up the area and I realized it wasn't working. I purchased a new sump and they even helped me put it in! Wasn't expecting that kind of service. Would highly recommend Advanced Radon Services."

"Robert was easy to get in touch with, and agreed to come by to stub a pipe into my draintile with very little notice.  He then came back to install the rest of the radon mitigation system, also spent over half hour discussing various aspects of home ventilation on the phone with me.  He did a clean, neat, professional job, although did leave me a number of small followup tasks to do.  Overall, a good experience."

"A+ It went great! Doug was early, and already had the out buildings inspected before I arrived. This left me time to focus on the home, which was the bulk of the inspection time. I really appreciated that, since I was on my lunch, and I am more concerned about the home than the other buildings. Doug was very thorough and explained why he would either flag or not flag an item. He explained what to look for when it comes to settling of a home, which eased my mind. It is also convenient that Doug has his own Radon detector. He set it up two days before the inspection date so we could review the preliminary results together. TEST FOR RADON! The price was very reasonable for something so important. It was high in this house, which is common for homes in MN and WI. I was then able to ask the owner to install a radon mitigation system."

"Rick and crew kept at it after first effort resulted in still-too-high radon levels. This if not uncommon, and Rick added solutions until a good test was achieved, at no additional cost. Would highly recommend."

"<p>The Tonna team installed a new central air unit and furnace.  The estimate was very detailed, and the job was completed exactly as described.  I specifically waited several months to post this review to assure that everything worked well through the winter months.  Everything has been excellent.  The bid was received on 8/21/13, and the work was completed in one day, 8/22/13.  I would not hesitate to refer Tonna Mechanical, they were extremely professional, thorough and easy to work with.  Tonna Mechanical also installed a humidifier on my new furnace a couple months later and it has worked flawlessly.  <br /> <br /></p> <br />"

"Andrew was quick to respond to our inquiry and set an appointment to come to our home, look at the site, and discuss any questions that we had. The pipe would exit near the front corner of our home and I was not looking forward to seeing the white pipe next to our siding. Andrew offered the option of having the pipe painted to blend with the siding color which resolved the question of esthetics. The project went perfectly. Josh was not only great with the installation and explaining the system to us, but was exceedingly careful with our home. I would highly recommend i radon to anyone looking for a system. They are great to work with, utilize a high quality fan, preform after installation radon testing, excel in communication with customers, and were able to find a paint color that blended very well with our siding. Had I known how great this project would turn out and what a terrific company i Radon is, I would not have procrastinated in completing this project.A+++"
