South Dakota is hard on an exterior. Freeze-thaw cycles, wind-driven rain, and full summer sun will find any surface that was not cleaned, scraped, and primed properly. That prep is most of the work and most of the reason a coat lasts.
Loose and failing paint is scraped back, bare wood is primed, and gaps that let water behind the siding get caulked before painting. Windows, roofs, and landscaping are covered.
Exterior work is weather-dependent, so schedules move. If rain moves in we will tell you and reschedule rather than paint over damp siding.
