Commercial Cleaning

Annastasia and her crew did an excellent job! We needed a commercial cleaning done ASAP due to new tenants moving in and she was able to squeeze us in the next day. She was a pleasure to work with and was very professional. I will use her for ALL of my future cleaning needs!

Tod S.

Commercial Cleaning

I just used JMK Janitorial for the first time and they are awesome! I had former cleaning ladies that did an OK job but if you want truly a good, really good cleaning service that will get the job done and even complete the request you may have, don’t hesitate to contact Purple Maids. They are the best hands-down! That’s why I rated them five stars because they are absolutely terrific and I recommend them to anyone who wants a really good cleaning service!
