ServPro cleaned the ceiling of a large room after a fire. The ceiling belongs to the landlord who did not file a claim. The rest of the room is covered by the insurance policy for the tenant. I want to cover the cost of the cleaning under the Extra Expense provisions of the tenant's policy because the tenant could not resume operations until the ceiling was cleaned. 

The insured's plant is a manufacturer of cannibis. That is why they have to operate in a clean environment. The landlord was not notified and therefore did not make a claim. The loss was considered by the insured to be his responsibility. Occuhealth, an industrial hygienist firm that we all use to determine the required scope, was hired to evaluate this claim. I have attached their report.

I just received the attached email from the company that did the original construction. Does this email verify that the insured's tenant's policy should cover the cleaning as part of the building claim? The lease agreement is attached.
