Lighting/Electrical

If you need light bulbs or ballasts installed, please have your Tenant Representative create a work order.  



Window Cleaning

The interior and exterior window surfaces are cleaned one time per year.  You will receive an email before the scheduled date of each interior cleaning to allow sufficient time for your staff to move personal items (i.e., books, papers, artifacts) from the window sill.  This enables the window cleaners easy access to the window surfaces to accomplish their tasks with minimum disruptions.  The window cleaners are not to handle or relocate items placed on or near window sills.
