The kitchen exhaust inspector was at this location when the KEC cleaning crew arrived. They even called their superiors to let them know the inspector was still there and would be looking over the system when they were done. The inspector left the site and came back in the morning after the cleaning was completed. There were new dated certification stickers applied to the exhaust systems. The FM for this location had to verify that these were actually "after" pictures of the competed job. This same company is supposed to provide pictures of the "clean" system to the customer, but obviously would have had to take strategic pictures to avoid showing most of the ductwork in the pictures below.
Here are the views looking up from below.
Here is the view from above looking down from the roof:
We are guessing this is the picture of the area that was sent to the customer by this vendor.
Or they sent these from another back system that does not get any buildup. Buyer beware on viewing pictures!
