"There is a reason for their straight A rating. Very responsive; outstanding work; complete explanation before, during, & after the job. Price competive! RRR stopped in to give me my third contractor's quote. It was obvious that Jim new what he was doing, and was not throwing in a bunch of unnecessary items to drive the price up. I hired him on the spot, I needed it done quickly as we were in process of closing on sale of the home. They did it three days later. A few days later my wife was checking for last items to remove from the house and heard hissing. Two very very tiny holes between the foundation and concrete floor, several feet away from the radon port, was sucking air. Jim stopped by a couple days later and sealed them. <br /> I hired them for a second install in our new home. Both jobs are top notch. 1st install was $1200 and more complex involving drilling through 18 inches of stone and mortar. 2nd install was $800. <br />"

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"All services were performed quickly. I called for a price Thursday and the installation was completed by noon on Saturday. The installer was very friendly and did a good job. Honestly, if this were for my home that I was moving into I would have considered another contractor and paid a bit more to have a neater, more hidden installation. But for a home that I was selling it provides the function it needs to. Nothing was done wrong or sloppy, but for the price it is a very basic installation in the easiest spot they could access. <br />"
