Painting contractors must also carry out administrative and marketing duties. They prepare final accounts for customers based on the original estimates and any additional work. They analyze the cost of the job compared with the estimate to calculate their profit. They market their business through activities such as setting up websites, asking customers for references or contacting property maintenance companies with details of their services.
If the point of hiring a well established, experienced, reputable painting contractor is to secure the professionalism and trust suggested to be inherent with that choice, then I would EXPECT that professionalism and experience to include the ability to make the proper and correct calculations for labor and materials for a fixed price quote, and there should be NO reason for the contractor to put the cost burden of their miscalculation on the consumer.
