Start with conditions, not a product
Frame material, flashing method, sill condition, glass package, and trim restoration carry as much weight as the brand name — sun exposure included.
Build a complete scope
- Whether the existing sash is repairable, which changes the recommendation entirely
- Whether openings are standard sizes or will need to be built to, common in mill housing
- How the opening is flashed and air-sealed, which outlasts any glass specification
- Frame material and solar heat gain for this climate, rather than insulating value alone
- Interior and exterior trim restoration, disposal, and what the warranty covers
High Point context
High Point includes furniture-industry neighborhoods, mill housing, postwar suburbs, and newer development across multiple counties. Rolling Piedmont terrain, red clay, mature trees, and humid storms make runoff and existing-condition mapping valuable.
