I would highly recommend A Best Environmental, LLC. and Larry Stone. From the beginning, Larry explained the entire process of reducing the level of radon gas entering my home. I accepted bids from a total of four contractors and chose A Best Environmental for several reasons: 1) Larry was very straightforward in answering all of my questions; 2) he guaranteed that he would bring the gas levels down to my satisfaction; and 3) he provided a very competitive price.

During installation we discovered that my house had been built using an unconventional construction technique which did not allow the described system to work properly. Larry developed a solution that proved to be successful, and the job was completed with the desired results. Though the work took a little longer, he did not alter the original cost estimate. Additionally, he tested all of my immediate neighbors at no charge when some of the other companies wanted over $100 to do so. None of my neighbors had a radon problem and Larry did not receive any additional work from the testing. This free service put the minds of my neighbors at ease and bolstered my confidence that I had picked the right company to solve my problem.

Dear Larry,

I am pleased to provide this letter of recommendation for the radon mitigation your company did at my home last month. I am thrilled with the results and am very pleased with the quality of your work. Your communication with me was excellent, you were always there when you said you would be—and on time—and you made every effort to reduce any negative impact this type of project can have on a home. Please feel free to use me as a reference.

Thanks again,

—Mary Beth T., Salem, OR

Hi Larry!

Just a note of thanks for your help with my real estate transaction. When my buyers had my house tested for radon at 6 or 7, I had thought the deal would fall through. I had looked for the cheapest price I could find that carried a guarantee and went with you. Wow, was I surprised! You were able to lower the levels to below 1, match the paint color of the house, have excellent workmanship, and get the job done within a couple of days of being hired! Thanks for proving to me that you can provide both quality and an excellent price!

Thanks again,

—Jeff H.


Thanks, Larry, for the great price and quick turnaround for my radon test. Your equipment was state-of-the-art and you were able to provide me with an hourly chart for my 3-day test. You arrived promptly both to drop off and to pick up the equipment, and you were able to show me the results on the spot on your laptop. All this for half the price I was quoted elsewhere!

Feel free to use me as a reference anytime.
