Commonwealth Environmental Associates, Inc.

The test and follow up went very well. The tech explained the results and is forwarding me documentation.

Great. Easy

Excellent Waiting on response from office or property manager.

During home inspection on the house we are selling, radon tested above acceptable level. Commonwealth provided an estimate of work to be done and cost. They retested, determined it needed mitigation, drilled a neat hole in basement floor, installed pipe that led to outside, fan, arranged for electrician, retested, and provided report - levels very good.

Went well!

It went well. He stated that I could do the job myself.

Crawl space looks beautiful and the Radon levels are well below EPA specifications.

CEA was excellent! From initially speaking with Fred Mayes and working with Sam Hull, the whole process was very smooth. They put my mind at ease and were meticulous in planning and executing the install. My system had to navigate four finished floors from the basement to the roof and they did an excellent job installing it and minimizing the obtrusiveness of the vent pipe. In the end they clearly demonstrated that the system was working and effectively solve three issues (Radon, excessive humidity and ejection well odor). Nice work guys! Thanks!!

Every aspect of the work and the services performed were great

I own a gym and spinal cord recovery center. We had severe roof leaks last winter and spring and several of my clients expressed concern about mold exposure. I chose to have this testing done in order to either remove mold or reassure my clients as to their health and safety. As it turned out we are mold free. The report which was given to me was very thorough and Kelly reviewed it with me so that I could explain it to others if questioned. I framed the report and placed it for all to see. This was a very inexpensive and reassuring solution to a valid concern.
Jod well done by Commonwealth Environmental Associates!!

It was great, Kelly was able to answer all my questions including The Crazy Ones. She was very informative on time and very professional. I would work with her again we had great repore.. I have referred her to of my friends and family.

We had a great experience with Commonwealth!  They were very professional, detailed oriented and prompt. We weren't familiar with the details of mold reports and Kelly was extremely helpful in explaining the process and the results.  They don't have any "skin in the game" to find mold, meaning they don't contract out any remediation work. That made me feel extra comfortable using them!  I look forward to using them again, should I ever need any mold testing done.

I have nothing but good things to say about my interaction with this company.  I say 'this company', but as we all know, it comes down to the individual.  The individual I had the luck to work with was Dan Goodman.  He was responsive, accessible, and demonstrated amazing ingenuity and persistence in resolving my issue.
I have a fairly nice house.  An external PVC pipe to remediate the radon issue was really not acceptable.  I, fortunately, have an  internal vertical chase from my basement to my attic to accommodate the exhaust from my gas water heater and furnace.  As it turns out, that chase is not exactly vertical.  Far from it.  Dan did not give up in the face of multiple issues.  He was able to route 4" PVC from my basement to my attic while maintaining the required 1" distance between the furnace/hot water heater exhaust pipe and PVC.  
Trust me.  I'm a pretty good DIY'er.  I couldn't have done what this guy did.  There was some minimal drywall repair (all in the interior of closets or cabinets) that he repaired.
I would highly recommend This company, and in particular, Dan Goodman.

The testing services were performed in a very professional manner and since the results were well below the government standard there was no need for any remediation efforts.

Before the system was installed, the Radon levels in the basement were almost 8 PCi/L when I did a short term test.  The electronic monitor I have was also showing levels varying from 10 pCi/L to almost 20 pCi/L from day to day.  
The Radon system installation went well and was done in a day.  Now that the new system is installed, the Radon is down to below 2 pCi/L in my basement, per the electronic monitor I have.  
The system is also quiet and the installation looks clean on the inside and the outside of the house.  I'm pleased.

Professional, responsive , neat.  No issues, system is working.

Easy and smooth

While preparing for a crawl space encapsulation project, it occurred to me to test for radon. The test came back 2.0 pCi/L, which is a level at which the EPA recommends retesting every 2 years. I was concerned the encapsulation could increase the radon level, so I found Dan online and called for his opinion. He advised that it probably would be good to put in the system before the liner goes down and that the radon could increase with the encapsulation (which will close off the vents that use to bring fresh air into the crawl space).

Dan was very responsive on the phone both in terms of reassuring me that this wouldn't be too bad to add on and in getting the estimate and work scheduled as quickly as possible to avoid holding up my encapsulation project. His business partner Ryan came out within a day or two to provide an estimate, and then they returned within a week to complete the work.

The system is nicely done at an inconspicuous part of the house. Since they were only installing the pipes and fan, they offered to return after the encapsulation is done to ensure the fan is drawing well under the liner (which would normally be part of a radon system anyway). They showed me how to check the pressure and clearly marked the exterior switch as part of a radon system that needs to remain on 24 hours a day.

Also, they used a licensed electrician to install the fan, and their price still came in below the other price I received. All-around professional yet laid-back guys who know their stuff and do good work. As an engineer I really appreciated their overall vibe.

We worked with Dan Goodman and his crew to lower the PCI/L readings in our finished basement. Dan was very professional and easy to work with. He was very concerned about not messing up our finished basement while at the same time, determined to get us the levels we wanted. He was upfront about expectations,was very punctual, and followed up on things that he said he would follow up on in a timely manner. He and his crew cleaned up after themselves which is a big plus! My husband was able to work in his upstairs office without noise interruptions. Dan installed 3 draw points and an exhaust fan that was appropriately sized for what we needed to do. (We can't hear it at all when inside the house!) The outside work blends in with our house and is not unsightly at all. (It looks like it is part of the house and does not stand out.) Dan was able to get our readings down from a 9 to .5 in less than 30 days. The EPA recommends readings be less than 4, with the understanding that the closer to zero, the better. Since radon is the #2 cause of lung cancer in the US and central VA has a higher level of radon than most areas, we felt we should be proactive and do what we could to reduce the levels in our home. We will retest in 6 months, but are very pleased with the results Dan was able to give us. Would highly recommend this company,
