Understanding Fiberglass Decks

Before exploring the costs, it’s important to grasp what makes fiberglass decks a sought-after option. Fiberglass, a material known for its strength and resilience, is ideal for outdoor applications. Its resistance to rot, mold, and warping makes it superior to traditional wood or composite materials. Additionally, fiberglass decks offer an aesthetically pleasing finish that can mimic various textures and hues, enhancing the overall look of your outdoor space.

Cost Factors for Fiberglass Decks

When calculating the cost per square foot for a fiberglass deck, several factors come into play. These include:

  • Materials: The quality of fiberglass and the resin used can affect the price. Higher grade materials, while more costly, ensure longevity and better finish.
  • Size and Design Complexity: Larger decks or those with intricate designs will naturally cost more due to the increased material and labor requirements.
  • Labor Costs: Installation of a fiberglass deck requires skilled professionals. The labor cost can vary depending on your location and the complexity of the project.
  • Additional Features: Elements such as railings, steps, or specialized coatings can add to the overall cost.

Average Cost Per Square Foot

On average, the cost of a fiberglass deck ranges from $15 to $30 per square foot. This price range is indicative and can fluctuate based on the aforementioned factors. It is crucial to get a detailed quote from a professional to understand the specific costs for your project.

Long-Term Savings and Value

While the initial cost of a fiberglass deck may be higher compared to other materials, it’s important to consider the long-term savings. Fiberglass decks require minimal maintenance, negating the need for regular painting or sealing. Their durability also means a longer lifespan, reducing the frequency of costly repairs or replacements.

Choosing the Right Contractor

Selecting a skilled contractor is paramount in ensuring the success of your fiberglass decking project. Look for professionals with experience in fiberglass installations and check their portfolio for previous work. A reputable contractor will provide a detailed quote and timeline, ensuring transparency throughout the project, like Unicomposite.

Customization Options

Fiberglass decks offer a wide array of customization options. From color choices to textures, you can tailor your deck to match your personal style and complement your home’s exterior. Discuss with your contractor the various options available to enhance the appeal of your fiberglass deck.

Environmental Considerations

In today’s eco-conscious world, it’s worth noting that fiberglass decks are a sustainable option. They are long-lasting, reducing the need for frequent replacements and minimizing waste. Additionally, the production process of fiberglass has a relatively lower environmental impact compared to other decking materials.


In conclusion, while the cost per square foot of a fiberglass deck can vary, its benefits of durability, low maintenance, and aesthetic appeal make it a wise investment. By understanding the cost factors and working with a qualified contractor, you can create a stunning, long-lasting outdoor space that enhances the value and enjoyment of your home.
