Exterior painting that holds up on the plateau
Paint fails on the outside of a house for one reason: what was under it was not ready. Loose paint, bare wood, open joints and mildew all have to be dealt with first, or the new coat peels on the same schedule the old one did.
Why exterior paint fails early up here
The Cumberland Plateau sits well above the surrounding valleys, and the weather shows it: more rain than the Tennessee average, humid summers, and winters that freeze and thaw repeatedly. Every freeze pushes moisture into any crack in the paint film, and every thaw lets it out. That cycle is what lifts paint off wood siding and trim.
Shaded north-facing walls and anything under a tree canopy stay damp longest, so mildew shows up there first. Painting over mildew does not kill it; it just hides it for a season.
Scrape, sand, prime, caulk
Loose and peeling paint is scraped back to a sound edge and the edge is sanded so it does not telegraph through the new coat. Bare wood gets primer, because topcoat on bare wood soaks in unevenly and fails. Mildew is washed off with the right cleaner before anything else happens.
Open joints where trim meets siding, and around windows and doors, get caulked. That is what keeps water out of the wall, and it is the step most often skipped because nobody sees it once the paint is on.
Siding, trim, doors and porches
Wood siding and trim take the most prep and reward it the most. Fiber cement board holds paint well once it is clean. Brick and block need a masonry primer and a breathable coating, not the same paint as the trim. Metal railings and doors need rust dealt with first.
Porch floors and steps are a different job from walls: they take foot traffic and standing water, so they get a floor and porch enamel, not wall paint.
Exterior painting: questions people ask
What time of year can you paint outside?
Exterior paint needs the surface dry and the temperature in the range the paint maker specifies, usually above 50°F and staying there overnight. On the plateau that means late spring through mid-fall for most products. We schedule around the forecast rather than the calendar, and we will tell you if a week is not going to work.
Do you pressure wash the house first?
The surface has to be clean before it is painted, and mildew has to be killed, not just rinsed. How we wash it depends on what the wall is made of. Old wood siding is washed gently, because high pressure drives water into the boards and raises the grain.
Will you paint over peeling paint?
No. Paint over a peeling surface peels with it. The loose material comes off first and the edges get sanded, which is the part of the job that takes the time and the part that decides how long the new coat lasts.
Can you match the existing colour?
Yes, from a sample chip or from an area of the house that has been protected from sun. Bear in mind that the existing colour has faded, so a fresh match to the faded shade will look different from what the house looked like new.
