Put the details in writing first
Note the location, timing, and any previous work. Photos and simple measurements make the first call more useful.
Read the local context
Two questions decide how straightforward this is. First, what the association requires, since exterior appearance in a planned neighborhood is usually subject to review and that is separate from anything the town asks for -- worth settling before a product is chosen. Second, what is actually installed now: a great many houses here received their original windows within the same few years, so a neighbor's recent project is genuinely informative about what you will find. Measure a few openings before shopping rather than assuming a standard size.
Ask what disappears behind trim
Frame fit, flashing detail, and how well the sill sheds Piedmont clay runoff decide the outcome far more than the window label. The written scope should explain what gets verified before it's no longer visible.
Look at the full scope
Materials, permits, testing, cleanup, and change-order terms should all be written down.
What official local sources add
For windows the operative record is designation, and it applies narrowly. On a designated property, windows are among the exterior elements most closely reviewed, and that 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, so it is worth confirming by address rather than by neighborhood impression. Far more Cary homeowners will encounter a homeowner association's exterior standards instead, which are private and separate from any city process. The stormwater system does not reach windows at all.
