"If there were a letter grade higher than A, then we'd give them that! This was a great experience, with great results. The owner,
--who" was on the job the whole time--was extremely knowledgeable, informative, helpful, patient, flexible...and seemed like a great guy, to boot. Same for his hard-working crew. They took their time, completed a good-looking installation, and cleaned up afterwards. The Radon level in our basement rec room before the installation was a little over 7 pCi/L (picocuries per
); the EPA recommends that mitigation be implemented for anything over 4 pCi/L. After
& crew finished, our level is now an average of 1.2 pCi/L...which is *well* under the red line. We're really happy with that result; it was well worth the cost. Best of all, we can now stop worrying about spending time in our rec room, which we're in the process of remodeling. We whole-heartedly recommend this team. A++ (or whatever comes before A!)

"We thought they did a great job explaining everything. I feel more comfortable knowing my kids are safely sleeping and playing in our basement without the threat" of elevated radon levels causing them
cancer later in life. Great work

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.

Homebuyers need to know that shopping for a radon system is like shopping for any appliance; you get what you pay for. (Photo courtesy of Angie's List member James B. of Chicago)

Radon Testing reviews in Irvine


Irvine Radon Mitigation Experts Provider Name Locked
did a very thorough job of not only inspecting our house-to-be, but also explaining what he saw as he went. He made sure we understood each issue and how we could fix it or who we could contact to fix it. I was very impressed with his ability to relay information so we could understand what he was talking about without making us feel stupid.

We received our results for both the radon test and the inspection quickly. Unfortunately, the radon test came back elevated, but because the homeowner entered the home after it started and did some work to the house, the test was skewed.

came back out and did another test for us, which showed consistently high levels.
Irvine Radon Mitigation Experts Provider Name Locked
provided us with the information we needed to make a decision about the radon levels and who to contact to best mitigate the house.

If we ever buy a house again, we would definitely use

and I would recommend him to anyone who needs an honest, thorough, informative home inspection.

is responsive and very prompt. He worked with my real estate agent to confirm a date & time and installed the system right away. I'm impressed with his professionalism and so is my agent.
- Kay R.

A job well done!!
- albert B.

The service went fine. One technician came out for the job. They did a good job. I had no problem scheduling the deal.
- Danielle C.

The technician arrived on time and had a fantastic attitude. He had a very professional manor and a teaching spirit. He explained the work ahead of time and made us feel comfortable with the decision that needed to be made. He performed the work in a timely manor and explained the system afterward. I will definitely call this provider if I ever need service in the future.

and the team were great! We had a very difficult situation with multiple pockets of radon and a rate that was tough to tame. They did the initial system, professionally installed it so that it is all but invisible and several days later tested. The test showed the radon was reduced but way above the safe level.

came back and installed an adjunct to the system, depressurizing under the garage floor. Again, reduced but not acceptable.

then came to the house a few days later, bringing very sophisticated air and soil sampling equipment and uncovered yet another pocket and then within a week had that area addressed. The rate was greatly reduced but still not at the acceptable level.
Irvine Radon Mitigation Experts Provider Name Locked
came back and covered our basement with sensitive testing equipment. He discovered another pocket and had
Irvine Radon Mitigation Experts Provider Name Locked
come back and depressurize in that area. That did it! We are now literally and figuratively breathing easier!!
Irvine Radon Mitigation Experts Provider Name Locked
was professional, persistent and very understanding of our concerns. He and his crew installed the system that had minimal visibility and maximum effectiveness. HE also stuck to his guarantee. He reduced the radon level to under 2.6 pc/l at the initial agreed upon fee - not a cent more - even though his crew spent many hours over 4-5 days to get it done. If you're looking for a professional quality radon mitigation company, I couldn't recommend

more highly.

was highly responsive and attentive. Mr. Davidoski arrived exactly on time and there were no problems. I am very satisfied with the radon install.

The U-level for the fan was almost
Irvine Radon Mitigation Experts Provider Name Locked
- he told me this was what it should be. I never had the radon restested as I was having a backup sump pump put in soon after. From what I saw and how low our level initially was, I figured it wouldn't be a big deal. After the backup sump was in, I called and asked if he could come back and reseal the sump cover. Initially he said he would do this- but when I called said the type of pump would make it hard and that a plumber should. Fair enough. However, the plumbers were saying it should be a radon guy. Eventually called another company who came out and found huge issues. Numerous standards of mitigation were ignored by
Irvine Radon Mitigation Experts Provider Name Locked
. The fan that was put in was reading 1.8 on the level-
Irvine Radon Mitigation Experts Provider Name Locked
said this is where it should be. The company that makes the fan said optimum should be 0.5-1. The foundation pipe was blocked- it had to be drilled through to remove concrete...
Irvine Radon Mitigation Experts Provider Name Locked
didn't even check this. With his instillation, the fan would move,
Irvine Radon Mitigation Experts Provider Name Locked
, 3 cubic feet per minute! We also had a separate unfinished area with plumbing rough ins- he didn't even check them, but they were supposed to be sealed as well- there needs to be a vacuum of pressure created. He also used the wrong type of caulk to seal the edges of the floating slab. When confronted with these allegations, he has no clue how the fans would/should work and said 3 cubic feet/minute should get my level down. He claimed since I never retested, I had no proof it didn't work. Before using him, go to the states website and read the standards these professionals need to adhere to...
Irvine Radon Mitigation Experts Provider Name Locked
skipped SEVERAL of the standards. What's worse, he didn't see the error in his ways. I knew I wouldn't get a refund from him, I just wanted him to know how bad a job he did. I reported him to the state as well. I suggest you choose other mitigators in the area.
