On the average, how often should one repaint the exterior of a house in the midwest?
8-10 years should be an average. But there is many things that will affect the longevity of any paint job;
* What is the shape of your home before painting? Good, bad?
*What prep was done and how?
*What primer, caulking and paint was used? How was it applied?
*What are the weather extremes between repainting?
Everyone of these questions can changed the lifespan.
