Leticia from Master Janitorial has cleaned 4 of our buildings for about 3 years now. She and her crew have done fabulous work and we couldn’t be happier. Very happy with their friendly customer service. They are competitively priced as well…I would say mid-range …but do great work !

We have used Master Janitorial for 12 years and are very, very happy with their service. Lisa, their office manager, has really helped us out whenever we needed additional cleanings after parties, etc. Their work is always very consistent and reliable. They are well-priced and their customer service is top notch !

Francesca’s crew from Master Janitorial Service has been sooooo wonderful. We have been happy with her. Unlike other companies in the past they have kept the same cleaner for our building and they are doing a FABULOUS job !!!

We have about 12,000 square feet of cleanable space and we’ve used Master Janitorial Service for the past 4 years. The company prior to them wasn’t satisfactory in their detail work but Master Janitorial Service really excels in their detail work…highly recommend them if you are as picky as me !!!

The cleaning staff from Master Janitorial Service has been on time, every time during for our day time cleaning. On the rare occasion when they couldn’t make it, the office staff informed us ahead of time and they arranged for another crew to clean for that day and there were no issues. Highly recommend this cleaning company. We have been using them for almost 4 years now.

We have our building cleaned 3 times a week and have used this service for 4 years now. I love Master Janitorial Service because of their reliability and consistency is what I was sold on and is why I have kept them. They have been in business for 50 years and you can see why !
