Company Commentary...

“ZEROREZ cleans carpets more effectively than any other carpet cleaners. No other cleaners have the technology that leaves carpet cle aned, sanitized and residue-free . We also hol d a higher customer service standard than that of our competitors. We not only want to leave our customers satisfied with the job done, but we want to create ‘raving fans’!”

Zerorez Reviews

“I was so impressed with the quality of work and the professionalism of the technician. The carpet looks wonderful!”


“Great service from every technician we have had over the last 5 years. Very easy to schedule online. Superior commitment to service and quality from the whole company.”


“The technicians are pleasant and professional. They are respectful of my home and properties. I believe in the product of Zerorez. I appreciate the clean feel, with no residue. My brother works for a competitor company. We choose Zerorez even still. It is a better product!”


“The service guys were very professional and did an excellent job. Helped to educate me on the cleaning of carpets, how often cleaning is needed and how to extend the life of a carpet. They were also very careful of our furniture and not tracking any dirt into the house.”


“We have used Zerorez twice now, and both times the technicians have been extremely nice. The people make the business, and you have great people!”
