Single & double hung.
Familiar proportions. A fresh start.
Hung windows use vertically moving sashes. Single-hung products usually operate at the lower sash; double-hung models allow both sashes to move. Confirm the actual operation and cleaning features of the proposed model.
What to settle before you order
Review sash weight, balance servicing and how tilt mechanisms work. For character homes, compare meeting-rail position and frame dimensions with the original elevation.
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.
