the service call is for the technician comming in after hours to the shop and driving out to the job, the min. price would before extraction if the area was small. Look at the blue book for the description of the two, but in my book they are two different services. You have to pay your tech extra money to get up and come in right, So thats what that price is for. Then you have to pay for the gas and machine use time, either min for starting the machine, but mostly a price point to cut you between min. price and sq.ft.

ok so to be clear.... you are saying... exmample... firday night call to extract water.... blue book says charge $100 an hour(just example) and service charge it $150 so total bill is for $250 or is total bill for $150.... just want to make sure i understand this...I mean i have a 500 Min and there is no service charge in that... its just $500 even if bill does not come up to $500 which almost alway does....

If someone calls me on Friday night it means put away the blue book and get out the check book!!!! A friend of mine is a locksmith. Friday @ 5:00 until 8:00 Monday morning is all 2x time. If they say anything he gives them the name of another locksmith and the number of the bar where he can be reached.
