Terrible service. Avoid at all costs if you want a decent service! Ordered 3 windows, they delivered all 3 windows with no beads whatsoever. They posted the beads to me a week later all packaged up in one bundle with no markings to show which bead went where in which window. Some of the beads were too short in length, some of the beads were missing altogether. Modern UPVC windows now want me to measure the windows and tell them what length the beads should be. What a joke of a company. The windows were delivered in February, and they are saying they cant send anyone out to measure the beads until April!! On two of the windows, the sashes are next to each other so the handles are right next to each other when closed, it is very clear that the handles do not align. Once again, they have offered me no help, other than to say someone will come and have a look in April!! AVOID AT ALL COSTS!!
