Cost of composite deck boards

Usually, a composite deck board will cost you from $3.19 to $5.80 per foot. This cost is only for the materials and does not include installation and other charges. Most composite decks are made of reclaimed or recycled materials such as PVC (polyvinyl chloride) or polyethylene (LDPE or HDPE) plastic mixed with rice hulls, wood fiber, and other fillers along with a blend of multiple chemical additives. There are primarily three types of composite materials available in the market – polyethylene plastic, PVC and polypropylene plastic. Polyethylene plastic is strong, light and has a very high resistance to most chemicals such as acid. Poly Vinyl Chloride, also commonly known as PVC, can be both flexible and rigid. The rigid form is very popular for structural work. Polypropylene plastic, on the other hand, is tough and has a very high resistance to heat. It is also resistant to fatigue.

Factors that determine the final cost

Composite decking is not a cheap affair. However, there are some factors that have a direct impact on composite decking prices. If budget is a constraint for you, the following factors can help you to keep the price on the lower side.

1. The deck size

The size of the composite deck has a direct relation with the final price. Larger the deck, the higher the price. Reductions of a mere 50 square feet will help you save between $1,500 and $2,000. You may also want to go for a more basic design to reduce labor costs. Keep this pointer in mind while building a deck.

2. The deck corners

You may wish to have fashionable corners that will make your guests go wow. However, the more complicated the design you choose, the higher the labor cost will go. Be ready to pay at the rate of $60 per hour, if you want to go for a complicated design.

3. Structural obstacles

The area where you intend to install the deck also has a say in the final price. If there are obstacles that need to be removed, it will add to the installation cost.

4. Substructure

If you do not have an existing substructure, you will need to build one. This will cost you an extra $4 per square foot.

5. Accessories

Luxury can never come cheap. If you want to add fashionable lighting or need some plumbing work, you will need to pay an extra $60 to $90 per hour for the labor charges.

6. Removing an old deck

If you need to remove an old deck to be able to install the new one, you will need to shell out anywhere between $5 and $15 per square foot, depending on the type of vendor you choose to go with.

7. Leveling

If you are looking to install the deck on level ground, it may cost you between $300 and $1000 to get the leveling done correctly.

8. Time of installation

As you know, spring is the season when most Americans prefer to get the composite decking done. However, if you choose to get it done during fall or summer, you can expect some discount deals.

9. Choice of vendor

Choosing the right professional to get the job done is never easy. While the reputed vendors may come at a higher price, they have an established credibility and reputation in the market. You may want to take quotes from multiple vendors to ensure fair pricing.

Now that you know the approximate budget that you need to have to install a composite decking, what are you waiting for? Get your dream composite deck today!
