Radon Control Unprofessional would be much more appropriate. We setup an appt window between 9 and 10 am. At 10:20 no one had arrived and no phone call. I called and told she would contact the technician and call me back. 25 minutes later I received a call from the tech who said he was 35 minutes away. Based on our conversation he was unaware of the original appointment time. I called RDC to inform them that I was frustrated that the tech would arrive more than an hour late as I had other appts however no one answered. I left a VM asking for them to call me back. Well it’s 2:30 in the afternoon and no call back. The tech arrived at approximately 11:35 and was good. I have no complaints about the tech. He replaced the fan (which was under warranty) and now the system is working. I confirmed with the tech that he was not notified of our appointment until I called. My complaint is with the complete lack of contact with the company. The service fee was $150. I tried several times to talk to someone at the company with no luck. I wrote a check for $125 and left a message stating that If that was a problem to contact me. I would never use them again.

Since we were selling our house we were not able to be present at the time of service although our agent was there. We initially thought we had to replace the fan. Their tech came there and check it all out and said there was nothing wrong with the system and that it failed because it was on the same circuit as the sump pump. They did not replace the fan (which they could have and no one would have been the wiser) and only extended the wiring to another outlet on a different circuit - at MUCH lower cost. He even troubleshooted our sump pump and figured out that it was going bad and causing the problems. 
So for honesty and quick service these guys get an A++++ rating from me.

The technician, Pete, was prompt, and walked through what he was going to do including making sure it met building codes.  The basement is also musty and saw that we have a crawlspace that he said may be causing the smell.  He walked around outside and saw that the venting windows for the crawlspace was obstructed and recommended we open it before making an installation.  He was did his work with no damage.
Their phone system is not so reliable.  I tried calling about four times but could not get through.  I don't know if the phone was off the hook or if they are really busy

UPDATE: It has been a year since we had the radon fan installed by this company.  I had originally gave it a "B" rating, but have now downgraded it to an "F" because we now have leaks in our guest room ceiling where they installed the fan above it.  Every time it rains hard, we get a leak.  Although the owner responded to my initial review, they have done nothing to try to rectify the issue.  Their service cost was lower than other companies, but we are paying more now to fix the damage to our home.  I would NOT recommend this company to anyone.  This is the first "F" rating I have ever given to any service provider.

ORIGINAL REVIEW ON 9/29/2014

My husband handled the scheduling of the radon fan and was here for actual installation.  He said the installation went fine.  When I arrived home, I could hear a very loud humming/vibrating sound coming from one of our bedrooms.  My husband said it was loud and the installer noted that as well, but said let's give it a few days to see if it still bothered me.  It sure did, so I asked my husband to contact Radon Control Professionals to move the fan to the outside of our house.  My husband insisted that he will take care of it, so he sent Jule an email.  4 business days go by and no response, so I decided to call them myself.  Julie answered the phone and I asked if she had received my husband's email.  She said it was in her inbox, but somehow overlooked it.  I gave her the benefit of the doubt and just asked her to respond to my husband's email.  She said she would and would have someone by the name of Steve call my husband.  It's been 2 weeks and still no call or email to my husband.  My husband didn't want to make a big fuss about this and decided to go to Home Depot and buy sound installation to buffer the noise himself.  My issue is not so much the inital installation by Radon Control.  It is the lack of customer service thereafter - VERY disappointing.  My husband said they offered the best rate around and chose them because of all the positive reviews on Angie's List.  I would have much rather paid a little bit more money for the good customer service before and AFTER the installation.

Response from Radon Control Professionals Inc
"Thank you for the generally good review and I would like to explain our response to activating your 'builder's pipe'. Please understand that all we did was add a fan to the pipe that was installed by your builder. We had no control over the fact that he installed the pipe above your bedroom and we have also had complaints that homeowners hear vibrational sound from within walls where the builder attached the pipe incorrectly. I am currently working with the Director of the Radon Division of the VA Health Dept who would like to require that builders use certified radon mitigators to install these 'passive' pipes. This would eliminate these noise and other issues that have occurred with builder's installations. Stephen Hall, MS, PG President, Radon Control Professionals, Inc.

The 2 guys were professional and kind. They explained what was going to happen before they started and explained the system once it was installed. The did not have a drain pipe that matched the color of our home but came back about a week later with a matching pipe. I was not charged until the work was completed.

Radon Control Professionals is an outstanding company. They are very knowledgeable, reasonably priced, punctual and finished the job in the timeframe quoted with exceptional results! We could not have asked for a better outcome and are extremely pleased with their work and customer service.

They turned our frustrating discovery of radon into their problem and we are now essentially radon free with lower levels in our house than the air we breathe outside! With two young children, that peace of mind is priceless. I would highly recommend this company to anyone.

In short - quick and painless process.
We called the company up, got a price (not estimate) over the phone and scheduled the installation date and time. The radon tech arrived on time and within ~3 hours had the system 95% installed. He drilled 3 approx 1/2" and 1 x 3" hole in the concrete slab. He mounted the 3" PVC pipe in the 3" hole and caulked the rest. He completely caulked our sump pump pit. He needed an addition section of pipe or the outside portion so he returned the following Tuesday to install that (we did not have to be home).
We also received a radon test kit from the company which is our responsibility to put in place for 2 days and then send off to a testing laboratory for analysis.
The most impressive thing about this company is the LIFETIME warranty on everything except the outdoor fan (which is warranted for 5 years -- which is still very decent). The warranty details clearly were written by a company (not a lawyer) who are very confident in their product and service. To exerpt some of the highlights::
  • RCP guarantees to reduce the radon levels to below 4 pCi/l for the life of the home.......

If a valid test is preformed which indicates levels above 4 pCI/l, RCP will pay for the test and perform further work at no expense until the level is reduced below 4 pCI/l.

These guys really know what they are doing. They charge about ½ of what other people charge. They are very professional and they have very good prices. I have been able to notice the difference; problem solved. They are the only ones I would use in the future if needed.

Great...no problems. The vent motor outside is quiet and the pipe going above the roof does not look bad (looks like a rain gutter).

I worked with Norm Rodier and it was fantastic. He clearly explained everything he needed to do to fix the mold that our home had due to a flooded basement and the price was reasonable. During the job, Norm found more extensive mold damage to our bathroom vanity. I expected him to change the quote and add labor and materials, but because he hadn't included it in the estimate, Norm only charged for the materials (buying a new vanity at home depot). I was blown away. that was a few years ago and the vanity is working great and the mold has not returned.

Great work and highly honest and professional.

It was a fairly simple job, and they finished it quickly. The service fee seems a little high for the little amount of work. I appreciated that they alerted me to another problem that required emergency service by a different contractor.
Response from Radon Control Professionals Inc
"I appreciated the 'A' rating in all catagories except the 'C' for the price of $350 which is the standard DC metro area price to replace an out-of-warranty fan. Our fans are warrantied, not by us, but by the manufacturer. So, the price is based more upon our fan cost than the time involved in labor."

Everything went very well. The technician noted that the pump had been moved during a remodel and reinstalled incorrectly. It had been bolted to the house rather than resting on the exhaust pipe. They corrected this problem. Now the new pump runs quietly.

We are in the process of selling our home. The home inspector (who apparently was absolutely incompetent) selected by our buyers had a huge list of "problems" for which we spent over $1200 to have various professionals come out to tell us...that there was no problem. The idiot inspector stated that the equipment was in a "very unusual place" on the exterior of the house, that it was plugged into a GFI plug, which was a no-no, that it had no gauge, blah, blah, blah. Now you must understand, I always research everything extremely thoroughly, and when we had the equipment installed, it was by a gentlemen we found on Angie's List who was the most highly recommended. He has since gone out of business locally, but the two companies I called to check the equipment both asked who had done the work, and both said he was a highly qualified professional who would have installed everything to code. Sure enough, when John came out from Radon Control Professionals, he said the equipment had been properly installed on the exterior of the house (which he told me is the most common way to install it), that a GFI plug was the safest electrical supply, and that if a gauge had been installed, it would have filled with water whenever it rained. He documented all of this on his service ticket so I could supply the information to our buyers.
Response from Radon Control Professionals Inc
"I appreciate the 'A' ratings in all categories except the 'D' in price. We are required to be certified, licensed and experienced and had to make a special trip for the client, out of our way, in the extremely geographically extensive and expensive DC metro area. Does anyone think that $166 for such professional services in this inflated economic climate is excessive?"

I called Jim at Radon Control Professionals upon the recommendation of my neighbor who is a realtor. She uses them exclusively when a home she sells needs radon remediation. I had called another company who was highly recommended on Angie's List and was quoted a price of $825 for a radon installation. Since Jim's price came in lower and he was recommended by a trusted source, I went with him. I called him on a Wednesday and he set me up for an install on the following Monday. He told me that he would not be the one coming to install the system himself but would be sending out one of the members of his team, all of whom have been at the company for at least 7 or 8 years I believe he said. The installer, Paul, was punctual, courteous, and very knowledgeable. He recommended installing the fan beside our HVAC unit to be as unobtrusive as possible and attaching the venting pipe right next to our existing down spout. I'm sure no one will even realize we have a radon unit because it blends in so well with the gutter and is hidden behind the HVAC. He took care in the basement to install the pipe as close to the wall as possible so that it didn't take up much space in the room. And when he was finished, about 3 hours from the time he arrived, he showed us everything he had done and explained how to read the gauge and told us what to expect in terms of the life-span of the fan. I could not have been more pleased with the whole process and I would definitely recommend this company to others.
