REGION — For Jesse Loughlin, owner and founder of Blue Mountain Painting, projects run the gamut from basic touch-ups to complete exterior repaints. Although quality is the main product, trust is what it’s all about. “People call us because they have a problem to solve,” Loughlin said. “I need to figure out what that is and offer the best solution.” Loughlin, who grew up in Southborough and Berlin, chose to build his business in the communities he knows best.
