"Above ground tank removal in a very TIGHT space behind a paneled basement wall which we did not want removed. Other estimates were less expensive but they all wanted the wall removed... by the time I paid a carpenter to take the wall down and put it back up, the price was agreeable and fare. David was wonderful, and work was done on time and neat... you could not even tell that a tank was ever there. Excellent job."
