(BPT) - Of the more than 60 million decks in the U.S., it is estimated that 50% are "past their useful life" and in need of repair or replacement, according to a report by the North American Decking and Railing Association (NADRA). If yours is among them, consider this. As long as your substructure is in good shape, resurfacing the walking surface with high-performance composite can be a simple way to breathe new life into your deck, requiring about the same amount of time and energy as resurfacing with wood. And, you'll never have to stain your deck again.

Composite decking, like Trex®, has gained popularity among today's homeowners who relish not having to sand, stain or seal the surface every year and who appreciate the eco-friendly nature of the material, which is made from mostly recycled and reclaimed materials. Better yet, with a little know-how and a few standard tools, even a novice DIYer can install it.

Following are a few tips for taking your existing deck from wood to "wow" by resurfacing it with high-performance, low-maintenance composite decking:

Resurfacing is different than rebuilding - Unlike building a deck from the ground up, deck resurfacing involves removing and replacing the deck boards with new materials to give it a fresh, updated look. Think of it as a facelift for your deck! Installing composite decking will also extend the life of a deck with boards that are warrantied to last anywhere from 25-50 years or more.

A firm foundation is key - Before pulling up any boards, assess your deck's foundation to ensure it is structurally sound. Start from the ground up by examining the footings, posts and joists. Pay close attention to the condition of the wood. Discolored or spongy wood indicates rot and should be replaced before proceeding. As long as the framing and substructure are intact, you're good to go.

Use your resources - You don't need to be a building expert to tackle a resurfacing project. Utilizing online design tools and cost calculators can help you with product selection and budgeting. There are also step-by-step videos, installation guides and how-to articles available to walk you through the process.

Resurfacing an aging or decaying wood deck with new composite decking is a doable DIY project that can be completed over the course of just a weekend or two. You get a brand-new deck for a lot less money than starting from scratch, and a lot less hassle through the years.
