In follow up testing, following their radon mitigation they accused me of (lying) by not timely dropping off my radon test kits. When confronted with verifiable information to contradict their position, they agreed to refund my money for the test kits, but no longer wish to guarantee their mitigation. This should make anyone nervous. Are they just making a quick buck and not mitigating properly? I now need to do follow up testing through another company, to verify it was done right. That is an unforeseen cost. Consumers beware!
Response from Rocky Mountain Radon Control
"First, we did not perform a service for [Member Name Removed] He bought my EPA/Neha canisters from the UPS store. He performed the test and returned the canisters too late to be analyzed correctly. [Member Name Removed] signed his forms on May 13, 2017. He then stated he ran his test on June 16, 2017 but that is crossed out too. He insisted we were lying , we said we never stated that. In addition, we did not put in his original mitigation system. We replaced his Fan ONLY RP265 on October, 13, 2014 We tried our best to help [Member Name Removed], but when people can't follow directions what can you do but give him a refund. [Member Name Removed] Lucero original testing form and invoice will be inserted into this response 7/17/17 when the business center opens on Monday. Thank you, Shelley, President Rocky Mountain Radon Control 303-980-1961"

I knew from the initial call that we would use this company. From the start, Shelly (who answered the call) was professional and had a great attitude. Getting the quote was easy and efficient, as was scheduling the appointment.The work was actually done by the owner and his crew. The owner was great, explained everything, and did really good work. I would highly recommend this company to anyone in need of radon mitigation.

Our realtor set up for a radon mitigation system to be installed in our home. We were told the price would be $850.00 and that he had set up for us to pay the invoice after our closing date on July 18th. The installation was completed on June 15th. Upon arriving the installer brought in all of his stuff and a file which he left on the counter. When he was finished he gave me an invoice for $920.00. After he left and after talking to my husband we were confused about the price increase and called our realtor. He called and spoke to the company. The company indicated that the reason for the price increase was due to additional work that had to be completed. This was absolutely a lie since the invoice was clearly printed before the worker had even looked at or started work in the home. Our realtor told us he didn't want us to have to pay the extra cost so he went ahead and paid $100.00 towards the invoice. I went on the companies website to pay the remaining invoice but could not find a way to pay it on their site. I immediately called and left a message asking them to call me. I wasn't worried about paying yet though as we were told we could pay after our closing date on July 18th. We were completely blown away today when we received an extremely nasty message from Shelley threatening to put a lein on our house if we did not pay the invoice immediately. The amount had also increased again to $950.00 this time. I called Shelley back and can honestly say I have never in my life dealt with someone that was so incredibly rude and unprofessional. An example is when I was giving her my email address and she was going over the email address letter by letter. When she got to the d, she said D as in Dick making sure to say it as nasty as possible. She continually interrupted me through our conversation and was beyond rude, disrespectful and unprofessional. I looked at the newest invoice she sent and again the amount was $950.00 when we had been quoted $850.00 and had received an invoice for $920.00. The address and name on the invoice are also incorrect. The full $100.00 that our realtor paid was also not entirely applied.

Just had some work done by this company. We didn't hire them. We are buying a house and the seller's realtor hired this company to do the radon mitigation work. Our realtor made a mistake with regard to location of the mitigation system. As far as I know the work was done without issue and I believe it is probably just fine/satisfactory. However, I had some questions about the installed mitigation system in our new house. I called the company and spoke with "Don". I I assume I was speaking with the owner of this company, Mr. Don Bronson. He made it clear within 2 minutes of talking to him that he had no time or interest in addressing my questions. Truly blown away with my experience with "Don". No sensitivity. No customer service. Angry man. And it appears he is not a good business person either because I was on the verge of allowing him to do more work on my home for which he would have been paid. He never even let me get to that part of our conversation. "Don" made it clear that he had no need for my questions or business. In the end I have decided to simply go with someone/anyone else. I would not/could not recommend this man or his company. Don, if you read this, please know that just a hint of patience and listening goes a long way. That said, given the anger you expressed, I doubt my constructive criticism or advice will be welcome or understood. I have read other reviews and they make reference to Shelly Bronson who I assume is related to "Don", maybe his wife. Perhaps Shelley should take calls and questions and "Don" should just focus on the work and not interact with his paying customers. Of note, an "F" grade/review on Angie's list dated 09/19/13 describes to a "T" the experience I had. Coincidence?, I think not.

This was very noninvasive. Meaning, they only needed to run an electrical line into the basement, everything else was connected from the outside of the house. They were all very polite and clean. The job only took a couple of hours.There was an additional air pipe from the sump pump system, it was covered with caulk to help make the radon removal the most efficient possible.After the underlayment was in stalled over crawlspace floor the plastic was billowing up, due to air flow underneath. Within 1 minute of radon fan being turned on, the plastic was pulled tight to the dirt. Proof of how well the plastic was installed, and how well the fan, pulling are from the underground French drain, worked. Don was exceptionally knowledgeable about radon gas, potential problems, and the fixes.They also filled the cracks in my concrete to prevent any radon from entering the finished basement.Don also checked on possible mold growth and located a few spots, minor, but we will have to repair. Shelley, in their office, was very pleasant and quick to respond to my quote request and follow up questions.Thanks so much, this will make the space so much better and safer.

I would highly recommend Rocky Mountain Radon Control to anyone needing a radon system installed in their home or business. We were closing on our home and needed a system installed that would reduce the radon levels to a safe level. Shelly and Don are true professionals that care about doing a great job at a fair price. They did EXACTLY what they said they would do WHEN they said they would do it. With all the things going on in closing the sale of your house, it's great to be able to depend on a company like Rocky Mountain Radon Control. Great Service and Great People!

They called before they headed over and arrived right at the beginning of the window of time they had promised. They were also courteous. The only thing is they didn't do is paint the white PVC piping they ran up the side of the house. I know both the other companies who bid the work promised this and I thought they had as well.  Unfortunately,  I had someone else at my home for that stage of the job and also when they left.  I will be calling them tomorrow. Fortunately they were a bit less expensive than the other two bids and I am not afraid of a paint brush, if it comes to that.

The installation caused a vacuum to build in the sump pit causing the sump pump to not function properly.  This caused a flood in the basement.  When I contacted the owner, Don Branson, he was extremely rude and would not let myself or the contractor talk with him about the issue.  He screamed and yelled and talked over me on the call and did the same thing when the contractor called him.  
This company is not very helpful and treats their customers very poorly.  I would not recommend this company to anyone looking for a high quality product and respectful treatment.
Response from Rocky Mountain Radon Control
"First [member name removed] is one of the many people affected by the flooding we have had the last week and to that I am very sorry. Unfortunately, [member name removed] is very confused. The most effective way to reduce radon is to go through the sump pit hole (see EPA/NEHA guidelines). The radon system and the sump pump are two separate systems. Radon systems remove air and the sump pump removes water. There is no way the suction from the radon system could affect the sump pump. If anything the radon system helps because it is moving air which would dry out water. I hope [member name removed] the best. Sincerely, Shelley Bronson Rocky Mountain Radon Control 303-980-1961"

My 87year-old parents sold a home recently that belonged to my sister who died in an accident. The home was willed to them, but due to their age, I managed the sale process for them. I am their eldest son.
   During the buyer inspection phase it was discovered that the house's radon fan did not work and the levels of radon in the basement were over the acceptable limit. I decided to remove the fan myself and purchase a new one locally. I called around and the "radon specialists" in the  area REQUIRED that I buy a new fan through them and it was mandatory that they install it. The pricing of these other contractors was outrageous and I decided buy a fan from Home Depot, put it in myself to quickly facilitate the final sale.
   Yeah ... things aren't so fast sometimes.
   I ran into problems right away. Home Depot, Lowes, Amazon ... you name it ... all needed 7 days to ship in a new radon fan. And, I really wasn't sure that the fan was defective in the first place. My testing indicated that it might be electrical.
   When I contacted Rocky Mountain Radon Control, Shelly and Don were AWESOME. 
   Shelly patiently walked me through all of the potential "gotchas" as to why these moody fans fail. Shelly patiently took 4 additional calls and I STILL couldn't fix it. When I called back the 5th time, I told Shelly I was "done" and asked her how soon I could get someone out. Don, the owner, was dispatched to arrive early the next day.
   Don and his Assistant arrived on time and proceeded to put in a new fan. When they were finished, I went to turn the power on and - wouldn't you know it - the new fan didn't work either. Immediately Don and his Assistant began troubleshooting and before long it was determined that the problem was indeed electrical. Don suggested some alternative wiring scenarios and I decided on the quickest and cheapest. After about an hour they had a new conduit and switch run to the fan location. It was then that Don suggested trying the old fan to see if it worked, and, sure enough the fan fired right up. Instead of spending $500, Rocky Mountain Radon Control saved us $250 by suggesting we keep the old fan since it worked fine. We really appreciated their high-integrity and can-do professionalism.
   I HIGHLY RECOMMEND this company. We would not have closed escrow on the sale of my sister's property without their prompt actions. The house passed the new radon test -- which Rocky Mountain Radon provided for $40 including a final report within 24 hours. The house closed escrow on-time and without a hitch. Thanks Very Much, Don and Shelly of Rocky Mountain Radon Control !!

My house is for sale and I had to have a few repairs taken care of, including having tested high for radon. I actually had three repairmen in the house and was on the phone, when Don and his 2 helpers arrived. My daughter let them in and showed them where the stairs to the basement were.



Fifteen minutes later, I was able to check with Don, and he had chosen the best spot for the system. He explained why he chose it and I agreed. They promptly went to work and a couple of hours later, he showed me the work they had done.



They used tarps on my floors to protect them. They moved things as necessary to reach where they needed to work, then put them back in place. They cleaned up after themselves very well. My only (very minor) complaint is that they accidentally removed the exhaust hose from my dryer, when they moved it, and we had to reattach it the next day.

As we were not living here at the time our realtor set up the appointment, met with them and had only good things to say about their service.  As I recall he said they were "Spot on".  We all were very happy with their service.

Very slick and easy.  I picked up the test kit at a UPS Store in Littleton for $35.00.  There were clear instruction inside on what to do and how to do it.  Then 48+ hours later I dropped it back off at the UPS store.  Even though it was late on a Saturday afternoon, they had emailed me the lab report before the end of that day.  Luckily, I didn't need any mitigation.  But they were a good bunch to deal with.  I called twice before using them to understand how things worked, and they were very pleasant and efficient.
I'd use them again if I needed this type of service.

Overall working with Rocky Mountain Radon was great.  They were very professional and right on time.  I appreciated having a say on where to put the system.  They caulked all the cracks in the basement and cleaned up. I would recommend them to anyone.

We have an older house built on bedrock in the foothills which apparently makes radon mitigation difficult.  After contacting several other companies for estimates (some wouldn't even give an estimate due to where we lived) we contacted Don.  We asked him to come up and give us an estimate, he was very professional and extremely knowledgable.  He was able to give us an estimate of each stage of the mitigation enabling him to do one stage at a time and test between stages.  He came up the following week, the install was extremely quick and efficient.  We only had to do two stages and met the EPA standards.  We had been quoted as high as $4000 with no guarantee from other companies.  Don was able to do this for $1800 and guaranteed that he would get us to the EPA standard.  We really appreciate all his help.

I was referred to Rocky Mountain Radon Control by a close friend that had a great experience with them.  I called and spoke with Shelley on the phone.  She was very friendly and patient.  I was buying a new home and upon inspection, I noticed a small area in the shower of my master bathroom that looked like mold.  I needed someone's expertise in inspecting it and taking care of it if it was mold.  With the home inspection, I needed a radon test.  We scheduled a time for Donny to come out and look at the mold and set the radon test.  He was very knowledgable about radon gas and treatment!  And equally as knowledgable about mold!  It turns out only a small area was actually mold, but Donny and his co-worker treated the area and got rid of it completely.  I was so thankful that it wasn't a bigger area and hadn't spread up into the wall.  After the radon test was processed, Shelley called me with the results and explained that my radon levels were slightly high and would need to be "mitigated".  She went on to explain what that meant.  She explained that Donny and a co-worker would come in and install a system that would pull all the radon gas out of our house and vent it to the outdoors.  She was very clear about what it would cost and that's exactly what I paid.  Donny and his co-worker showed up to put the system in and seemed to be very efficient!  They were both very respectful of my home and behaved professionally!  They came when they said they would come and finished when they said they would finish!  I really appreciated that!
I have a lot of peace of mind knowing that I had someone that was knowledgable about these dangerous indoor hazards.  From what I understand Donny has been in this industry for about twenty years.  It showed and I appreciate that.  These things aren't something you mess around with.  If you are going to pay the money to get a radon mitigation system or mold treatment, you need to pay someone that knows what they are doing!!
I will confidently refer Rocky Mountain Radon Control to anyone that has a need for these types of services!

Fabulous.  Rocky Mountain Radon Control arrive in a clearly marked van. The owner and worker introduced themselves and explained what would be taking place and approximately how long.  The owner was Don Bronson.  He was most knowledgable, friendly, clean cut.  The entire installation was approximately 2.5 hrs.

The company came out to examine my property and took a radon sample from my basement, for which they charged $150. They sent the sample to an independent agency who found that the level in my home was above the recommended 4.0pCi/I. They stated that I could select any company I wished to install a system if I decided to go ahead with the purchase. Due to their professionalism, I selected them and found that they deducted the price I paid them for the estimate from the installation of the system. It took less time than they estimated to install it. I am very pleased.

The experience was unique, I've never seen a radon inspection before. The inspector told me everything he was doing and the reason for everything he was doing. The house came back with acceptable levels of radon, which eased my mind.
