How To Start Planning Your Deck

A gorgeous deck starts with a great plan. The Trex design tool can help you during the planning stages, too. Here are a few things to consider while you plan your dream deck:

  • Size & use: How do you want to use your deck? Do you plan to do a lot of grilling and entertaining? Or do you just want a small, backyard sanctuary to soak up some sun? How you plan to use your deck will play a role in determining its size and scale.

  • Budget: Do you have a set budget in mind? This may play a role in the size and scope of your deck, or extra features you want to incorporate. When planning your deck, consider not only the cost of materials, but the cost of labor.If you plan to go the DIY route, you may have some extra wiggle room in your budget, but it may take longer to build than if you’d hired a professional. Use the app to compare pricing on different components and view estimated costs for your deck—both with and without labor factored in.

  • Maintenance & materials: How much time do you want to spend maintaining your deck—and how often? Composite decking gives you the look of natural wood without the drawbacks. Fade-resistant, rot-resistant, and termite-proof, composite decking requires comparatively less maintenance than wood decking. Once you know what materials you plan to use, the Trex Deck Designer can help you create a shopping list for your project. Learn more about Trex vs. wood.

  • Obtaining proper permits: In most cases, yes, you will need a permit to build a deck. While adding a deck to a home can increase the value—and enjoyment—of your home, if you haven’t obtained the proper permits, it can be a problem if you ever choose to sell. Once you’re done designing your deck in the app, you can use the Trex Deck Designer to generate a blueprint to take to your local building office to be sure it meets safety codes and to apply for the proper permits. Learn more about the legal requirements for building a deck.

  • Timing: The amount of time it takes to build a deck varies based on a number of factors, including: the size, shape and components of your deck, as well as how many people are building it and the skill level of those involved.For instance, if you want to enjoy your deck during spring and summer months, you’ll want to start obtaining permits during the winter months. Weather conditions may also impact the timing of your project. Wet ground due to rain or cold temperatures can make it difficult to install posts or lay a foundation. Rocky terrain and making sure the ground is level can also increase the time frame toward completion. If you live in an area that has cold winters, you may also need to account for time for the ground to thaw and drain before you can get started. The Trex Deck Designer can help you plan ahead so you have plenty of time to enjoy your deck.
