A method for repairing a turbine blade (10) is described. The turbine blade (10) usually includes a root portion (20); an airfoil (12) having a pressure sidewall (24) and a suction sidewall (22); and a tip (18) disposed between the two sidewalls (22,24). The method includes the steps of removing substantially all of an upper region (42) of the tip (18), and then rebuilding only a portion (54) of the upper tip region (42). The portion that is rebuilt generally extends from the suction sidewall (22). Another embodiment is directed to a method for repairing or modifying a turbine blade (10) that includes a squealer rim (34) extending above both a pressure sidewall (24) and a suction sidewall (22) of the airfoil (12). The squealer rim portion (34) that extends from the pressure sidewall (24) is removed, while leaving in place the squealer rim portion that extends from the suction sidewall (22).
