"I am over the moon happy with my deck that was designed for my new hot tub. They matched my current deck and put up new railings to tie them both together. They looked like they were made at the same time! I will be enjoying the deck for many years to come. All the workers were kind and professional, and of course very talented!"

Lewistown, located in Mifflin County, Pennsylvania, boasts a rich history dating back to its incorporation in 1795. Named after William "Bill" Lewis, a Quaker and state legislator, the town was originally known as the Village of Ohesson. Throughout the 19th century, Lewistown became a vital transportation hub, thanks to the construction of the Pennsylvania Canal and subsequent railroads, which spurred economic growth and industrial development. The town's strategic location near the geographic center of Pennsylvania made it a bustling center for cargo and passenger traffic during that era. However, the decline of the canal system and industrial challenges in the 20th century led to economic shifts. Despite these changes, Lewistown has experienced a resurgence in recent years, with new businesses and infrastructure developments enhancing the community's vibrancy.
