Zerorez technician Chris and his coworker arrived on time, surveyed the areas that I wanted cleaned and recommended the best options to preserve the carpet and tile floor. They worked efficiently to complete the job in short order. Both took care to make sure hoses were kept off wall corners and they wore shoe protectors whenever inside my home. They were pleasant and professional in all respects. I've used Zerorez in the past and would wholeheartedly recommend this company to friends and coworkers.
