5 Benefits of Replace Wood Deck Boards with Composite

1. Durability

Composite deck boards are made from a combination of recycled wood fibers and plastic, making them incredibly durable and resistant to rot, splintering, cracking, warping, and splitting. This makes them an ideal material for decking in harsh climates or areas with high levels of moisture.

2. Low Maintenance

Compared to wood, composite decking requires very little care and maintenance, which needs regular staining, painting, and sealing. Composite boards are also resistant to common issues like mold and mildew buildup that come with wooden decks over time. This makes composite a great choice for busy homeowners or those who don’t want to spend their weekends doing upkeep on their outdoor spaces.

3. Environmentally Friendly

Most composite decking materials are made from recycled materials like wood and plastic, meaning they are much more eco-friendly than their traditional wood counterparts. By using recycled materials and reducing the need for cutting down trees, composite decking can help reduce your carbon footprint.

4. Aesthetics

Composite boards come in a variety of colors and styles designed to mimic the look of real wood. This means you can have the classic, natural beauty of a wooden deck without all the upkeep that comes with it.

5.  Long-Lasting

Composite boards are resistant to rot and insect damage, making them incredibly long-lasting. With the right care and maintenance, composite boards can last up to 25 years or more, depending on the quality of materials used in their construction. This makes it an ideal choice for those looking to invest in a deck that will stand the test of time.

5 Common Mistakes People Make When Trying to Replace Wood Deck Boards with Composite

1. Not Removing the Old Deck Boards Completely.

One of the most common mistakes people make when trying to replace wood deck boards with composite is not removing the old deck boards completely. Removing all of the old decking and any nails or screws that may be holding it in place is important. Failure to do this can result in the new composite decking not being installed properly and not lasting as long as it should.

2. Not Using Proper Support When Installing the New Decking.

Another common mistake is not using proper support when installing the new composite decking. The new decking needs to be supported adequately in order to avoid sagging or warping over time. Be sure to use joists that are spaced 16 inches in the center, and use two stringers at the edges of the deck for added support.

3. Not Pre-Drilling Holes for The Screws.

Many people also make the mistake of not pre-drilling holes for the screws when installing composite decking. This can result in the screws stripping out over time or breaking altogether. Be sure to predrill all of the holes for the screws, and use a countersink bit so that the heads of the screws are flush with the surface of the decking.

4. Over-Tightening the Screws.

Another mistake people often make is over-tightening the screws when installing composite decking. This can cause the screws to strip out or break and damage the composite material. Be sure to only tighten the screws until they are snug, and do not overtighten them.

5. Not Using End Caps or Edge Trim Pieces.

Finally, many people also fail to use end caps or edge trim pieces when installing composite decking. These pieces can help give your deck a finished look and protect against water damage and rot at the edges of your deck. Be sure to use these pieces when installing composite decking for a professional-looking finish.

How Do You Prevent Mold and Rot from Building up On a New Composite Deck Board Installation?
