"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.

"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.

Same quality and company, NEW NAME!!!! Yep we've upgraded our branding to better reflect out company goals. As always, quality products are essential for success, but without certified and trained technicians installing everything to the exact specifications for greatest success, your home wouldn't get the best results. That's why we do things right - every time. Our excellent products come with extended/lifetime warranties INCLUDED - there will never be an upcharge for a warranty. The adage "you get what you pay for" is 100% true for Insulation Geniuses. We'd rather explain the investment up front rather than trying to explain quality for the next 20 years...
