Reservoirs in the mountains
The City of Asheville's 2025 Annual Water Quality Report says the city has three main water sources: the North Fork and Bee Tree Reservoirs in eastern Buncombe County, surrounded by 20,000 acres of protected mountain forests owned by the City of Asheville, and the Mills River facility in Henderson County.
That's the setting. The station figures below set the agenda for an exterior repaint, particularly the line about freezing and thawing.
The Asheville station, in NOAA's figures
NOAA's engineering weather data for Asheville lists a 100-year rainfall rate of 3.5 inches per hour, a 50-year basic wind speed of 90 mph, a 50-year ground snow load of 14 pounds per square foot, and about 67 freeze-thaw cycles in an average year. In an average year at the Asheville station, NOAA counts about 175 hours with the wet-bulb temperature above 73°F and about 1,426 hours above 67°F.
What a freeze-thaw cycle does to a painted surface
Each cycle is a round trip across freezing. Water in an open joint or a soft board freezes, expands, thaws, and seeps a little deeper before the next freeze. Paint itself doesn't mind the cold once it has cured. What it minds is water getting behind it. Most failures from freeze-thaw start at:
- Caulked joints where trim meets siding, at corner boards and around windows; old caulk shrinks and cracks, opening a path.
- Window sills and the bottoms of door casings, which hold water on flat or poorly sloped surfaces.
- End grain at the ends of boards and the bottoms of trim pieces, which drinks water quickly.
- Bottom edges of siding near the ground and above roofs, where splashback and snow sit.
Preparation aimed at those spots
A proposal for an Asheville exterior should spend words on the places above:
- cutting out failed caulk, not just running a new bead over it;
- choosing a sealant rated for movement and for the paint going over it;
- priming end grain and bare wood, including the undersides of sills where a brush can reach;
- replacing soft wood rather than filling it, where the damage goes deep;
- checking that wood is dry before primer goes on.
Ask how the painter handles each one, and whether repairs are priced separately.
Snow and the low parts of the house
Snow piled against a wall or sitting on a porch roof keeps the siding behind it wet as it melts. The lower courses of siding, the trim at the foot of porch columns and the boards just above a roof line take the worst of it. Expect a careful painter to look closely there and to mention it in the proposal.
Scheduling in a place with cold nights
Most exterior paints list a minimum temperature for the air and the surface, and many need it to stay above that for some hours after application. A careful crew watches the overnight low as closely as the afternoon high, and it saves the colder part of the year for days that clear the label's limits. The exterior painting page covers product choices.
If the paint predates 1978
On a house built before 1978, scraping failed paint at sills and joints may disturb lead. The EPA rule on the card below applies to paid work that does. Ask whether the painter's firm holds RRP certification.
