Document it before calling anyone
Note where and when it started, and anything already attempted. Photos help frame the first conversation.
Read the local context
Two property-level checks change what the right answer is. Establish what the existing windows are: original wood sash in the mill-and-rail core is often repairable and sits in openings that are rarely standard sizes, while the postwar aluminum and early insulated units are a straightforward replacement where the frame, not the glass, is the weak point. Then check the age of the paint layers on and around those openings, because in the oldest housing that governs how the work may be carried out rather than merely how it is priced.
Ask what won't be checked twice
How flashing handles a Piedmont thunderstorm, how the sill sits against clay soil movement, and how the frame meets existing trim matter more than the unit itself. A real scope spells out what gets verified before it's covered.
Review the entire scope
Protection, access, materials, permits, testing, and exclusions should all be in writing.
What official local sources add
Historic-district review is the operative record here and it applies narrowly. On a designated property, windows are among the exterior elements most closely examined, and review can reach sash configuration, material and profile rather than merely thermal performance -- none of which applies to an undesignated house on the same street. Confirm status by address before anything is ordered. Floodplain mapping and the stormwater program concern ground and water and do not reach an opening in a wall except through the scale of a much larger project.
