Q: Do you give estimates before completing?
A: Upon request I can try to estimate, as best as I can, how much labour it will cost/take. Even after I have made a diagnosis it can be uncertain as to how long the job will take, so this is only an estimate. The customer is still responsible to pay for the entire amount of labour it takes to repair the machine.
Also after putting in a new part, in some cases it may reveal the need for other parts, not discovered at the time of diagnosis. At that time the customer shall be notified. Should they decide they do not wish to install further parts at that time they do so at their own risk. They are still expected to pay for any parts they had already authorized prior to the discovery. In some cases failure to allow other required parts to be installed may void the warranty of the parts which have already been or will later be installed. Example: If it seems like the machine needs a new clutch, then I discover that the transmission is leaking onto the clutch and causing it to slip and the customer only authorizes installation of a new clutch and not replacement of the leaking transmission, then there would be no warranty on the clutch or the repair since the transmission interferes with normal operation of the clutch and contributes to premature failure of the part.
