Deck Material and Lifespan

Is your deck deteriorating after just a few years? As homeowners, we want our investment to last for as long as possible, and that’s where choosing the right decking material becomes crucial. With so many options available, it can be overwhelming to decide. In this blog post, we’ll guide you through the average lifespan of different decking materials, including wood, composite, Trex, steel, and PVC, and the factors that impact their durability. By the end, you’ll be equipped to make an informed decision for a long-lasting and cost-effective deck 

Wood Decking: 10-15 years

A classic and affordable choice for your deck. Cedar, redwood, and pressure-treated lumber are common wood types used for decks. Cedar and redwood have a longer lifespan than pressure-treated lumber, but all wood types are prone to insect infestations and rot without proper maintenance. A wood deck typically lasts around 10-15 years, depending on the wood type and maintenance practices. However, by regularly cleaning and sealing a wooden deck you can help extend its lifespan.

 Composite Decking: 25-30 years

Modern decking material, made from a blend of wood fibers and plastic. Its durability and low maintenance requirements have made it increasingly popular in recent years. A composite deck typically lasts around 25-30 years, depending on the quality of the material and maintenance practices.

One advantage of composite decking is its resistance to rot, insect infestations, and fading. However, exposure to UV rays can cause fading over time. To maintain the color of your composite deck, be sure to regularly clean and seal it. 

Trex Decking: 25-30 years

A composite decking material made from a blend of recycled plastic and wood fibers. It’s a durable and low-maintenance option, with an average lifespan of 25-30 years, similar to other composite decking materials. Plus, Trex decking is resistant to fading, staining, and mold, making it perfect for high-moisture areas. However, keep in mind that it can scratch easily, so it’s important to use gentle cleaning products and avoid abrasive tools that can damage the surface.

Steel Deck: 30-50 years

The option for you if you’re long for a strong and built-to-last option. Steel decking is made from steel sheets that provide a stable and durable deck surface when laid on top of joists. The average lifespan of a steel deck is around 30-50 years, depending on the quality of the material and maintenance practices.

Steel decking is an excellent choice for areas with high fire risk as it’s resistant to rot, insect infestations, and fire. However, exposure to moisture and salt can lead to corrosion and rust, which can shorten the lifespan of the deck. You can help keep your steel deck in top shape by avoiding prolonged exposure to these elements and practicing regular maintenance.

PVC Deck: Up to 50 years

A great choice for homeowners who want a long-lasting and low-maintenance deck. Made from 100% PVC and plasticizers, it’s resistant to rot, insects, moisture damage, fading, staining, and mold. With high-quality materials and regular maintenance, a PVC deck can last up to 50 years! Just be aware that exposure to UV rays, extreme temperatures, and heavy foot traffic can affect its lifespan. To maintain the color, all you need is regular cleaning and gentle treatment – avoid using harsh chemicals or tools that can damage the surface.
