Your Local Custom Deck Builder In the Lehigh Valley, PA
As a homeowner in the Lehigh Valley, PA, you want an outdoor living space that’s both inviting and functional—a place where you can entertain, relax, and spend meaningful time with family and friends. The problem is, your current outdoor space may feel outdated, uninviting, or simply go unused. That’s where Keystone Custom Decks comes in. We design and build stunning custom decks and outdoor living spaces throughout the Lehigh Valley and surrounding communities, helping you create the perfect setting for unforgettable gatherings, lasting memories, and a more enjoyable everyday lifestyle.
A well-designed deck gives Lehigh Valley homeowners more usable space for relaxing, dining, entertaining, and enjoying the outdoors without taking on a full home addition. A professional deck builder can help turn an underused backyard into an outdoor living area that fits the home, property, and way the family actually uses the space. From replacing aging boards and railings to planning a new multi-level deck, the right approach considers structural support, traffic flow, stairs, privacy, and long-term exposure to Pennsylvania’s changing seasons. Material selection also matters, whether the goal is the traditional appearance of wood or the lower routine maintenance of composite decking. Careful planning and professional construction help homeowners create a deck that feels connected to the house while making the backyard more functional throughout much of the year.
History of Lehigh Valley
The Lehigh Valley occupies much of Lehigh and Northampton counties and has been shaped by Native American history, European settlement, transportation, manufacturing, and several periods of economic reinvention. The Lenape lived throughout the region before large-scale European settlement. During the first half of the 18th century, German-speaking settlers arrived in growing numbers, while Moravians founded Bethlehem in 1741. Northampton County was formally established from Bucks County in 1752, with Easton becoming its county seat. Lehigh County was later separated from Northampton County and created in 1812. The region also played a role during the American Revolution and later developed into an important transportation and industrial center. Canals and railroads connected local iron, slate, cement, and other industries with expanding markets. By the 19th and 20th centuries, Bethlehem Steel became one of the Valley’s best-known symbols of its manufacturing economy. After the decline of heavy industry in the late 20th century, former industrial sites were redeveloped as healthcare, education, logistics, tourism, manufacturing, and other sectors expanded. Today, Allentown, Bethlehem, and Easton form the region’s major urban centers, surrounded by boroughs, townships, farmland, parks, and growing suburban communities. Learn more about the Lehigh Valley on the Lehigh County government website and Northampton County government website. Additional historical background is available on the Lehigh Valley Wikipedia page.
