We discovered mold in our bathroom and contacted Eco Tech for help. They were quick to respond, professional, and made the whole process much easier then expected. Would definitely recommend them!!
William and the Eco Tech Environment team was professional, reassuring, communicative, and most importantly extremely skilled at making sure our home was free of mold after our HVAC partially flooded the basement. They cared about getting rid of the mold as much as we did! They followed the strictest environmental standards to ensure the zone had negative air pressure and that their treatment was safe and effective. They also explained to us how the mitigation process worked each step of the way. They were on time, dependable, and very patient with our timeline which included having a third party company do mold testing, our scheduled vent cleaning and HVAC replacement. I wholeheartedly recommend them to anyone who needs help with an environmental job like ours. The Eco Tech Environmental team took very good care of us!
