Put the condition in writing
Track where it's showing, when it began, how weather plays into it, and past work. Photos and rough measurements sharpen that first call.
Read the local context
Two checks save most of the trouble here. Confirm what the homeowner association requires before choosing anything, since in these neighborhoods exterior color and material are commonly subject to approval and that is a private agreement no permit discharges. Then walk the elevations and note where the existing coating is failing -- on a lot with mature landscaping the shaded sides tell a different story from the sunny ones and need different preparation. Check the trim and the detail around the complex rooflines, which is where failures normally begin.
Ask what will be hidden
What's underneath the old paint, moisture, chalking, failed caulk, sun exposure, decides the prep and coating system more than any brand name does. A good written scope covers the prep and checks that won't be visible once it's finished.
Line up complete scopes
Compare protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranty, and change-order terms.
What official local sources add
Two separate approvals can apply and they are easy to confuse. Local landmark designation is the municipal one, and on a designated property it can reach exterior color and finish visible from the street -- but it covers a limited set of addresses rather than whole neighborhoods. The one most Cary homeowners actually encounter is the homeowner association, which in planned neighborhoods commonly governs exterior color and material and is a private agreement rather than a city rule, so it is not discharged by pulling a permit. The stormwater system has no bearing on paint, except where regrading or hardscape work accompanies the job.
Verified in 2026, flood zone, historic designation, and permit specifics still need confirming with the Town of Cary at the parcel level.
