Hatch Stamping has contracted with Koski Cleaners for several years now to clean a few of our facilities. They have done a great job and the owners are very competent, hard-working and honest. They have been a good company to work with and will go out of there way to satisfy their customers.

We have been using Koski Janitorial Services for several years. Tammy is very easy and very accommodating to work with. I especially recommend them if you need flexibility with your cleaning company. They have been great to work with.

Very friendly and efficient. And no cutting corners. Love these guys!

I have been using Koski Janitorial for several years for our businesses. The owner is always very responsive and dependable.

Great job Koski! Very friendly staff, they do a great job cleaning each week. :) Keep up the good work.

Out of all the cleaning companies that we have used this is by FAR the best company for the job. Strongly recommend them.

My employer uses Koski for a 50+ employee office setting (40 open cubicles and probably 10 actual offices) and they do a great job.

Koski janitorial services is a upstanding company that goes above and beyond what is expected in a cleaning company. They provide services that are high in quality and are very professional. This is the best company I have had and I highly recommend them over any other company.
