We bought a display home a few years ago which had Stegbar windows and sliding doors. Lately the sliding door has been loose and knowing that an 8 yr warranty was still current I contacted the Unley store for help. Nothing happened so rang the service number at Pooraka and was given instant help. Two days later Wally came and fixed the doors well. He was on time and pleasant so am now happy with the outcome. If further assistance is needed it is still available too.
