Bay & bow.
A different dimension of daylight.
Bay and bow assemblies project from the wall and combine multiple units. They change the room and the exterior, so the quote needs to address support, roof or cap details and the way the assembly connects to the wall.
What to settle before you order
Ask who designs support and makes good interior finishes. A replacement in an existing projection differs from creating a new bay in a flat wall.
Make the quote a complete picture
Ask for the manufacturer, model, dimensions, glass package, frame finish and hardware. The installation scope should describe removal, opening preparation, flashing, insulation, sealants, interior and exterior finishing, disposal and site protection.
Product and workmanship are different promises
Request both warranty documents and a named service contact. Record what happens if removal reveals concealed damage, and approve additional work in writing.
