This article explains how to determine if repair work has been done correctly following lost water pressure. The basics process of well, pump, or water tank diagnosis and the costs of the repair are explained.
Consumer advice on saving money on well repair costs includes a review of the parts and labor costs of a typical well pump and pressure tank replacement case.

IF the tank and pump replacement have completely fixed the symptom you were having, then the contractor seems to have made the correct repair.
However given the sequence that you describe, we understand that you'd suspect that there was nothing wrong with the pressure tank and that the problem, all along, was the well pump.
If the contractor were skilled and diagnosed that a bad tank was hastening the demise of or even causing the demise of the well pump, it would be poor practice to replace only the pump.
While a more sophisticated analysis (perhaps using an ammeter to look at current on the pump circuit, for example), might have detected at the outset that it was the pump that needed replacing, it is very common in all trades for a repair person to first replace, among the possible causes of a problem, the items which are less costly and most accessible - in this case, the water pressure tank. (Presuming your pump is a submersible down in the well.)
How to check on the success and reliability - the "prognosis" of a an expensive well pump and water pressure tank repair job
First of all, there should be no leaks, anywhere, on the equipment which was repaired. If something was left wet, wipe it off and check for leaks. We don't pay my plumber if s/he leaves her/his work leaking. We call the boss.
Second, everything worked-on should be working normally to your eye and ear.
An expert plumber or well contractor can check the operation of your system by a combination of observation and electrical testing, such as measuring the amperage draw on the well pump circuit during pump operation. If these parameters are in normal range you should be ok insofar as the equipment is concerned. Your repair person should have made these checks. Ask him or her.
If you have been in the home for several years you should have an idea whether or not you've had a history of the well running out of water. You can understand more about your well and how the well itself is performing by noting its technical statistics such as well depth, water level, pump depth, static head, and well flow rate - topics we discuss at my website. If it is determined that you have a low-yield well, there are several solutions besides just drilling a new well - itself a shot in the dark.
If the building water supply stops and takes minutes to hours to recover, you may have problem with the well flow rate. But the problem of lost water supply and pressure could be more mechanical: a bad well pump. The well pump, in turn, could have been damaged or hastened to the end of its life by a bad water pressure tank which has caused well pump short-cycling. Short cycling of the pump motor can burn up the pump relay control.
