THA Cleaning has been performing janitorial services for my Bellevue office for almost 4 years. They have always been reliable and provided an efficient cleaning service. I have been offered many proposals from other cleaning services, but I have had no reason to accept them because THA Cleaning has never let me down. I highly recommend their services!

THA Cleaning is the best cleaning crew I've ever encountered. Their attention to cleaning detail is surpassed only by their consistently outstanding communication. Our office runs more efficiently and professionally with their efforts.

Tayna, I wanted to let you know that your crew did an outstanding job on our offices this past weekend to where our members that use the rooms consistently took notice! The bathrooms, the kitchen and our plan room was immaculate! Thank you for all you and your crew does to make sure we look our best! Have a great week!
