Wood Decking
Wood decking remains a popular choice for its natural look and feel. Common types of wood used for decking include cedar, redwood, and pressure-treated wood. Cedar and redwood are especially favored for their natural resistance to decay and insects, along with their attractive aesthetic. However, maintaining a wood deck requires regular upkeep, such as staining and sealing, to protect it from the elements. Pressure-treated wood is a more affordable option but tends to splinter and check over time as it dries out.
Pressure-treated wood is typically the most budget-friendly, while premium options like ipe can be much more expensive. Despite the higher maintenance, many homeowners prefer the authentic look and feel of a wooden deck. Regular deck maintenance, including cleaning, staining, and sealing, is essential to extend the lifespan of wooden decks and keep them looking their best.
When considering wood decking, it’s important to think about the long-term commitment to upkeep. Applying stain and sealant regularly will prevent moisture from penetrating the deck boards, which can cause warping, mildew, and decay.
Using tools like a pole sander and plastic sheeting can help in preparing the deck surface for staining. Proper maintenance ensures your wood deck remains beautiful and durable for years.
Composite Decking
Composite decking, a mix of wood fibers and plastic, mimics natural wood and offers superior durability with minimal maintenance. One of the significant advantages of composite decking is that it doesn’t require sanding or refinishing, making it very low maintenance. High-quality composite decking can last for 25-50 years with minimal care.
Composite decking varies widely in price depending on the brand and features. While the initial cost may be higher than wood, the reduced maintenance and long lifespan make it a cost-effective option in the long run.
Composite decks are available in a variety of colors and textures, allowing homeowners to choose a design that complements their home’s exterior.
PVC Decking
PVC decking, made entirely from polyvinyl chloride (PVC), is known for its moisture resistance and lack of splintering or warping. This makes it an excellent choice for areas with high moisture exposure, such as around pools and surfaces that will endure Nashville rains. PVC decking is resistant to pests, mold, and color fading, which means it requires minimal upkeep and stays looking new for longer. Despite being one of the more expensive options, its durability and low maintenance needs often justify the cost.
PVC decking also offers the advantage of being lighter and easier to install due to foaming agents used in its manufacturing.

Nashville’s heavy rainfall can pose significant risks, making it essential to address water management in your decking design. Water is considered the greatest enemy of construction, highlighting the importance of effective waterproofing to prevent moisture damage.
Here are some effective solutions for keeping your deck dry and protected.
Flashing Tape and Joist Protection
Flashing tape is an essential component of deck waterproofing. It protects the tops of joists, rim joists, beams, and the ledger board from water damage. By preventing water from seeping into these critical areas, flashing tape helps extend the lifespan of the deck and reduce maintenance needs.
Additionally, using joist hangers and proper flashing techniques can further safeguard your deck against moisture-related issues.
Under-Deck Drainage Systems
Under-deck drainage systems are an excellent way to protect the joists and wood framing from water damage, thereby extending the life of the deck. These systems channel water away from the deck surface, preventing it from leaking onto stored items or living spaces below.
An above-the-joists drainage system is particularly effective as it provides complete protection from moisture penetration. Using deck ‘sleepers’ to raise the decking boards off the ground or roof allows the wood to breathe, further mitigating water damage.
Vinyl Membranes for Waterproofing
Vinyl membranes are a highly effective solution for waterproofing decks. These membranes provide slip resistance, enhancing safety on the deck surface. Unlike traditional sealers, vinyl membranes do not require re-application of fresh coats, reducing maintenance efforts.
