The durable construction and powder coat finish of AFCO Railings ensure that your deck remains safe and stylish for years to come, with a variety of color options to suit your home’s design.

Wood or Composite: What’s Best for Oshkosh Decks?

When it comes to selecting the ideal decking material for your outdoor space in Oshkosh, the debate often comes down to traditional wood versus modern composite materials. Both options offer distinct advantages that cater to various homeowner preferences and requirements.

Wood Decking: Wood remains a popular choice for its natural beauty and classic appeal. It offers a unique grain and color for each board, contributing to a traditional and authentic look for your Oshkosh deck. However, it’s important to note that wood decks require regular maintenance, including sanding, staining, and sealing, to maintain their appearance and longevity. Despite the upkeep, a well-maintained wood deck can significantly enhance the aesthetic of your outdoor living space, making it a worthwhile investment for those who prefer the natural charm of wood.

Composite Decking: Composite decking has gained popularity for its durability and low maintenance. This material combines wood fibers with recycled plastics to create a deck that closely mimics the look of real wood while offering enhanced resistance to the elements. Composite decks require minimal upkeep, typically needing only occasional cleaning to maintain their appearance. With advanced manufacturing techniques, composite decking now comes in a variety of colors and textures, providing ample design flexibility for your Oshkosh decks.
