"Excellent, very satisfactory. Radon Brothers' rep came, saw the problem, and replaced the leaking radon exhaust PVC pipe in my basement floor. All in record time. Am very satisfied and will continue using Angi contractors."

"adon After I contacted him, he responded promptly.  While evaluating the area that needed radon mitigation, he called to discuss an area that had not been evaluated by inspectors (not affiliated with him).  After accepting his price, we agreed on the day for the installation.  During the installation, he was respectful and communicative.  After completing the installation, he provided written warranties for me and the buyer.  I highly recommend Keystone Radon Mitigators.

Before starting the work, all details are meticulously explained and priced competitively. After the work is complete, same thing, comprehensive review of what was done. They go the extra mile, and it's obvious they take pride in doing it right and making sure the homeowner is 100% satisfied."

"ECO TECH provided excellent service and remediated the mold and performed the necessary air quality test. Workers showed up on time for pretest, remediation and final air test and results. Over and above this excellent work, Tom McGuire was instrumental in helping us deal with the company we had hired previously. The first company was not qualified to remediate mold because they could not perform the required air test and the mold grew back in a few days after they had supposedly treated it. Tom helped us contact them, spoke with them himself and hopefully we will be receiving a refund. ECO TECH is the real deal - professional, thorough,cost effective and reliable. Can't sing their praises high enough.
