Every grant has a chain of dates: approval, completion window, evidence. Held on the job, they announce themselves; missed, they cost the customer money and you the recommendation.
The survey produces the numbers the quote depends on: area, thickness, access, existing material. Kept on the same job, the second visit to the same house takes half the time.
Photos taken before, during and after are required for the grant and useful for the website. Attached to the job as they are taken, they exist when the file is submitted.
