Pierce Exterior SignA Little History…

Pierce Window & Door was founded by Scott Pierce’s parents in the mid 1980’s. His father had been a window and door craftsmen for a shop founded by Scott’s grandfather in the 1950’s and ‘60’s. By the time Scott was in high school, his father had retired. But, customers who had purchased windows and doors 30 years prior were asking his father for replacements. Mr. Pierce couldn’t turn his loyal customers away, so Pierce Window & Door began as a way to meet the needs of these very satisfied customers. Fresh from college, Scott joined the business in 1988.
