Common Composite Deck Problems in Denver, CO

Denver’s high temperatures and improper framing lead to frequent issues with trex composite decks. Mold, slippery surfaces when wet, and the inability to repaint are common challenges faced by homeowners in Denver who have installed trex decking.

Improper framing and high temperatures

Improper framing leads to many trex deck problems. It can cause sagging and uneven surfaces. Builders must use the right tools and follow Trex’s guidelines for smaller joist spacing.

This ensures the deck provides solid footing and lasts longer.

High temperatures pose another challenge for composite decks in Denver, CO. Composite decking materials, like Trex, absorb more heat than traditional wood or pressure-treated lumber.

In summer, this can make decks too hot to walk on barefoot. Choosing lighter colors helps reflect some of the heat away from your new deck.

Slippery when wet

Trex composite decking can become slippery when exposed to water. After a rain shower or around swimming docks, this issue is more noticeable. The surface holds water, making it challenging to provide solid footing.

Homeowners must be cautious during wet conditions to prevent slips and falls.

To manage the problem, keeping the deck clean is crucial. Remove standing water, leaves, and other debris regularly. Maintenance tasks such as pressure washing with care can also help reduce slipperiness by removing mold and mildew that add to the slick surface.

Mold and mildew growth

Aside from being slippery, another issue homeowners in Denver may face with their composite decking is mold and mildew growth. Moisture can get trapped on or between deck boards, especially after rain or snow.

This creates a perfect environment for mold and mildew to develop. These fungi not only look unsightly but can also cause the deck surface to become discolored over time.

Keeping decks clean is essential to prevent this problem. Regular washing with soap and water helps remove dirt that molds feed on. However, if mold has already taken hold, special cleaners made for composite materials may be needed to fully address the issue.

It’s important for homeowners to act quickly at the first sign of growth to keep their decks looking great for years.

Lack of ability to repaint

Trex decking lacks the ability to be repainted due to its composite material, made from a combination of wood fibers and plastic. This means that once the color fades or if you desire a new look, traditional repainting is not an option.

The limited ability to repaint may impact your long-term satisfaction with the appearance of your deck, especially considering Denver’s extreme weather conditions and the potential for color fading over time.

As homeowners in Denver, it’s crucial to consider this aspect when weighing your options for decking materials.

Factors to Consider Before Installing Trex Decking in Denver, CO

Consider potential supply-chain issues, installation difficulties, cost, and limited refinishing options in Denver, CO when installing Trex decking. 

Explore these critical factors before making your decision.

Supply-chain issues

Trex decking in Denver, CO faces supply-chain issues affecting availability and delivery times. The global demand for composite decking boards has led to delays in obtaining materials.

This impacts installation schedules and may require homeowners to consider alternative decking options due to extended wait times.

Considering the cost, installation difficulties, and supply-chain issues is crucial when evaluating Trex decking for your Denver home. These factors directly affect the timeline and budget of your deck project, requiring thoughtful consideration before making a decision.


Consider the cost of Trex decking as it may vary due to supply-chain issues and market trends. Installation difficulties can increase overall costs, making it crucial to obtain detailed quotes from reputable composite decking companies in Denver, CO.

Factor in maintenance costs too, since Trex decks have limitations on refinishing and color variations that may impact long-term expenses.

When considering Trex decking for your home, don’t overlook the cost implications associated with installation and maintenance. Understanding these factors will help you make an informed decision about investing in a composite deck that meets your needs without exceeding your budget.

Installation difficulties

Installation of Trex decking in Denver, CO may pose challenges due to the area’s extreme temperature variations and limited color options. Difficulty in finding skilled installers who are familiar with Trex products can also be a hurdle.

Additionally, navigating local building codes and regulations for composite decking installation is crucial.

Consideration of climate impact, cost, and potential limitations on refinishing will help homeowners make informed decisions about the installation process. 

It is advisable to consult with reputable contractors experienced in working with composite materials like Trex decking to ensure a smooth and successful installation process that meets both aesthetic and practical needs.

Limitations on refinishing and color variations

When it comes to Trex decking, homeowners in Denver should be aware of the limitations on refinishing and color variations. Unlike wood decks that can be sanded and refinished with a new stain, composite deck boards like Trex cannot be refinished.

This means once the color starts to fade or if you want to change the color, replacement may be necessary instead of refinishing.

Furthermore, while there are various colors available for Trex decking, homeowners should note that color matching when adding new sections or boards can be challenging due to potential color variations over time.
