Clarksville gets nearly 50 inches of rain a year, summer highs in the 90s with heavy humidity, and enough winter nights below freezing to open every hairline crack. That's a hard climate for paint. A well-done exterior job here still lasts eight to ten years on siding and a bit less on horizontal surfaces like decks and rails — but only if it goes on at the right time of year, on properly prepared surfaces. The two are worth understanding before you book anyone, including us.
The window. Exterior paint needs the surface and the air to stay above about 50°F while it cures, and it needs to stay dry for a day or two after it goes on. In Middle Tennessee that means the season runs from roughly April to the end of October. Late spring and early fall are the best of it: mild temperatures, lower humidity, long dry spells. Summer works too — we do a lot of July and August exteriors — but hot siding in direct afternoon sun makes the paint dry too fast and leaves lap marks, so we follow the shade around the house and start early. Winter is off the table for anything but a warm-spell touch-up.
Watch the humidity, not just the rain. On a muggy August morning the siding can be damp with dew until 10 or 11 a.m. Painting over that traps moisture under the film, and it shows up a year later as blisters and peeling. We check the surface before we start, and we won't paint an exterior the day before a forecast soaking.
Prep is most of the job. On a typical repaint the crew spends more time preparing the surface than putting colour on it, and that's what you're paying for. It starts with a pressure wash to get the chalk, mildew and dirt off — paint doesn't stick to any of those. Then every loose or peeling area is scraped and sanded back to a sound edge, so the new paint isn't sitting on old paint that's already letting go. Failed caulk at the windows, doors and trim joints is cut out and replaced. Bare wood and any rust on metal railings get a primer. Rotten trim gets replaced, not painted over. Only then does the paint go on, two coats, sprayed and back-rolled on siding so it works into the grain and brushed on the trim.
Vinyl siding can be painted. Homeowners are often surprised, but most of the newer houses off Fort Campbell Boulevard have vinyl siding that has faded, and it takes paint well once it's washed. The rule is to stay at or lighter than the original colour — a dark colour on vinyl absorbs heat and can warp the panels. The paint manufacturers publish vinyl-safe colour lists, and we work from them.
Decks and fences are different. They're horizontal, they hold water, and they get walked on, so they need a stain or a deck-rated coating rather than house paint, and they need refreshing more often — every two to four years for a stain. Pressure washing and letting the wood dry for a couple of days before coating is essential, and we won't stain a deck that's still damp inside.
