Duncan & Sons’ Commercial Cleaning and Building Maintenance Since 1989

Company Benefit Announcement

“We are so proud to be able to announce the addition of a 401k with company match to our benefit package for Full Time and Part Time employees. Providing our people with an opportunity to start preparing for their retirement has been a long time goal for us.” Luke Duncan


ES·SEN·TIAL: /əˈsen(t)SHəl/ – absolutely necessary; extremely important.
The Pandemic has redefined what essential really means. Jobs you might expect, Police, Fire Fighters, and Health Care Workers are now joined by Delivery Drivers, Grocers and Cleaners.

Essential, on the front line, doing what needs to be done. Our staff didn’t miss a day during lock down!  In fact disinfecting and cleaning has become the bedrock of businesses opening and staying open. 

Now that businesses are opening back up we are looking for more essential Staff!
