Security Screens - we had the majority of our windows and 3 doors done, 2 sliding and 1 double door, the sliding door lock broke within 2 years and was never fixed properly after contacting Westral and now after 6 years the locking mechanism in the front door has broken and they will not fix it without us paying a $99- call out fee (possibly $260 if needs fixing) and then costs on top even though they claim to have a 30year fault warranty. So remember that the locks only last 3 -6 years at the most and this is on the strongest crimsafe door. The door at the front cost us $1200, the sliding door $1500-. All our windows have been good.
