"My home was for sale and narrowly failed the radon test requested by the buyer.
was available to promptly come to my home and install a" mitigation system that was guaranteed to reduce radon to acceptable levels. Although I paid the bill, they worked with the buyer to design and install the system in a way that would be the least obtrusive. The price they charged for their services was reasonable and they were very flexible in working with me and the buyer.

"We called because we thought the fan had stopped working and to look into the issue of water dripping from the pipes in our garage during the winter. It turns out" the fan still worked as the power was turned off. It was good to know that they were honest and stated the fan did not need to be replaced at this time. They determined the reason water dripped from the pipes in the winter was due to having the wrong flange on the roof. They did a good job of fixing it. I can't wait to see if working this winter so I don't have to scrape the ice off my windshield on my car that is in a garage. Note: they are not the same company who put the system in place.

Radon is a colorless, odorless gas that occurs as a decay byproduct of uranium and thorium. Radon forms naturally in the environment, and low levels can be detected in soil, rock and ground water. Homeowners that inhale radon are at risk of lung cancer and even death.

Radon Testing reviews in Saint Louis


Great! Fantastic service. They had to come out an initial time, then returned another time. Very helpful, professional, and efficient.
- Meaghan L.

All went well. They installed the mitigation system to avoid as much basement use as possible and the system isn't obvious from the exterior of the house. All was done right on time and with little disruption and all was cleaned up afterwards. I had to call them back to rehook up the garage door opener, but they were a very short distance away and it was no big problem. They explained the entire process and left literature that would be a good reference in case of further questions.

was the person who came out to start the test and then to collect the machine two days later. She was very professional and we received a thorough report following the test. No problems - no attempts to upsell - highly recommend.

Saint Louis Radon Inspectors Provider Name Locked
was very helpful when I was in a difficult situation resolving the radon issue. He fit me into his schedule early, and went out of his way to help get the situation resolved quickly so I was able to sell my condo. The $900 was for the mitigation system only the cost of the tarping was not included in the above cost of service as this was a different company.

Working with
Saint Louis Radon Inspectors Provider Name Locked
from Pyramid was great, and very reasonable! I was buying a two-family rental property near St.
Saint Louis Radon Inspectors Provider Name Locked
Hills and was nervous because I wasn't sure if certain things were problems or not.
Saint Louis Radon Inspectors Provider Name Locked
did an amazingly through inspection (almost 3 hours!), and was really patient and funny as he explained to me what he was looking for, and helped me understand what was and wasn't a big deal.
For example I was concerned about moisture in the basement, e.g. if the foundation was cracked etc.
Saint Louis Radon Inspectors Provider Name Locked
identified that the outside sidewalk was slanting into the house, and was probably the source. Which was a whole lot cheaper of a fix than the foundation! He also found things with the water heater and stack which I never would have spotted! And he went everywhere, like the attic, unlike other inspectors I've worked with.
All the issues were documented in his super-thorough report and in my inbox within a day - and I actually used what he found to negotiate getting several thousand dollars off the final price for repairs!
The termite and sewer inspectors did a good job, which he coordinated, which made it easy for me.
So overall it was money well spent, and I will definitely use

again, especially when I need to buy a house for myself.

was great to work with. Not only he was knowledgeable, he was thorough in his inspection and also took extra time to explain different nuances of the house. His inspection report was clear, concise, and full of important pictures, which were invaluable for our negotiations with the seller's agent. He was friendly and professional. He also followed up with us a week after the inspection to make sure we are satisfied with the work. I would highly recommend Mr.

The radon mitigation system in our house had been installed by a different company called "Eagle Eye" for the previous owners as part of the sales contract. There were problems with Eagle Eye's work: their exhaust pipe ended two feet below the bedroom window, so we called them to extend it, and they proceeded to extend it to just below our 3rd floor window. Clearly Eagle Eye was not familiar with EPA regulations, and it eventually became impossible to get in touch with them; they may now be out of business (deservedly). So I consulted Angie's List to find a reputable radon mitigation company and decided to try

based on the glowing reviews.

inspected the system and identified other problems that I would not have had the experience to see. We discussed what needed to be done, and the two men did it efficiently and neatly. They strengthened the whole exhaust structure which had been prone to sagging; they eliminated an area where moisture could back up and freeze; they rerouted the exhaust pipe to the regulation 10 feet away from our attic window; they added a squirrel

When we were selling our townhouse, the buyer had the basement tested for radon by another testing company. It came out about 6 pCi/L, above the EPA safe level of 4.0. The other company didn't provide any back-up information, such as testing log, or chart, just a number. In the process of trying to get additional information from testing company, I talked to

Saint Louis Radon Inspectors Provider Name Locked
. I had already contacted
Saint Louis Radon Inspectors Provider Name Locked
for an estimate for mediation. He volunteered to do a retest of our townhouse. The result again came out over 4 pCi/L.
Saint Louis Radon Inspectors Provider Name Locked
provided all the back up information along with the average radon level. With all the information, I felt comfortable with the accuracy of the results and the need to proceed with radon mediation. Since our closing date was rapidly approaching, we needed to get the work scheduled and completed in fairly short order.
Saint Louis Radon Inspectors Provider Name Locked
coordinated the work schedule to meet our needs. After mediation and retesting, the radon level was reduced to about 1 pCi/L. The installers were prompt, did a nice job on the install, and did a good job cleaning up. I was very satisfied. As a result, I asked
Saint Louis Radon Inspectors Provider Name Locked
to schedule our current residence for radon mediation also. We had had the house tested prior to buying, but had not done the necessary mediation work yet.

scheduled a date, the crew arrived on time, and again did a very nice job with the install. Retesting showed levels below 1.0 pCi/L.
