It is the question we get on almost every exterior estimate, and the honest answer is that it depends far less on the paint than most people expect. Seven years is a good average. Whether you land above or below it comes down to preparation and timing.
Seven Years Is the Number to Plan Around
On a typical home in the Triangle, a properly prepped exterior repaint should give you around seven years. That is an average, not a promise. Raleigh summers are long, hot and humid, and the sun is strong: south and west facing walls take the worst of it and usually show wear first, and trim tends to go before siding does. Winters are mild, but they still swing through enough freeze and thaw to work caulk joints loose over the years.
Preparation Is What Actually Decides It
Two houses painted on the same street with the same product can age completely differently. The difference is almost always what happened before the first coat went on. Washing removes dirt, chalking, pollen, and mildew so the new paint can bond to a clean surface. Around Raleigh that step earns its keep: the spring pollen leaves a yellow film on every wall, and the humid summers grow mildew on any side of the house that stays in shade. Scraping and caulking deal with the places where water would otherwise get behind the finish.
Paint applied over a dirty or failing surface is sitting on top of the problem rather than solving it. It will look fine for a season and then let go.
Do Not Wait Until It Is Peeling Badly
This is the most expensive mistake we see. Once old paint is peeling badly, the prep required to fix it goes up sharply, and so does the price. Repainting on schedule almost always costs less than waiting until the failure is obvious from the street.

Weather Decides the Schedule, Not the Calendar
The surface needs to stay above 34 degrees for at least 24 hours after application. Air temperature at noon is not the number that matters, the surface overnight is. If the forecast will not hold, we reschedule rather than risk the finish. Between coats we usually get about an hour, though humidity and temperature change that, so we check the surface rather than the clock. Raleigh winters are mild, but clear nights in January and February still drop below that line, so the overnight forecast decides the schedule, not the month. Summer brings the opposite problem: afternoon humidity and pop-up storms stretch dry times, and when the remnants of a tropical storm are coming up from the coast we wait rather than open up a wall we cannot close before the rain.
What to Ask Whoever You Hire
- Ask what the prep includes: washing, scraping, and caulking should be named in the proposal, not assumed.
- Ask about weather rules: a crew with no temperature policy is a crew that will paint on a day it should not.
- Ask to see the work: photos of finished jobs like yours, and references you can actually call.
