The national direction is consistent everywhere: fiberglass overtaking steel for durability, multi-point locks becoming standard for security, energy-efficient glazing for better insulation, and low-threshold accessibility for long-term home value. What changes locally is how much of that work is triggered by failure versus choice, and how much the same scope costs.
