Document the condition
Write down where the problem shows up, when it started, how it tracks with weather, and anything you've already tried — a few photos help too.
Read the local context
Cary's building stock skews young and suburban, shaped by decades of subdivision construction radiating outward from the original rail depot, with Piedmont clay and increasingly complex rooflines adding to the load calculation.
Ask what will be hidden
Duct sealing, refrigerant charge, and electrical capacity all disappear behind drywall and insulation — ask what gets verified before the crew calls it finished.
Compare complete scopes
A complete scope names the access plan, materials, permits, testing steps, cleanup, warranty length, and how change orders get handled.
What official local sources add
Beyond the neighborhood-level picture, Cary's own historic-preservation and stormwater programs govern the drainage, easement, and landmark questions that only come up address by address.
