Question 1

What type of materials should I use to build my deck?

Accepted Answer

The framing or support system of a deck is typically built with pressure-treated lumber, which is more economical and less vulnerable to rot and insect damage than many natural wood options. When it comes to decking, stairs and railings, a variety of materials can be used, including pressure treated wood. Upgrading to certain wood species, such as redwood, cedar and ipe, can provide natural beauty as well as weather and pest resistance. For low-maintenance deck options, check out solid vinyl and composite decking. They're made with recycled plastic and wood fibers to provide a durable and lasting surface.

Question 2

How do I determine what size deck I need?

Accepted Answer

Your deck should be sized to fit your furniture and allow for foot traffic, without being large enough to detract from the design of your house or yard. Consider how you intend to use the area and how much space you’ll need to enjoy it comfortably. Also, keep in mind that local codes or HOA rules may limit the size of decks. Pros often recommend allowing two feet of space to walk around furniture without exceeding 20% of the square footage of your home, or the size of the largest room. Careful planning can help you avoid building a huge deck that is out of scale with the rest of your home, or one that is too small for your family’s needs.

Question 3

How can I maintain my new deck?

Accepted Answer

Many wood species are naturally resistant to moisture and insect damage, but adding a layer of protection with stain, paint or sealer is a good investment for all wood decks. Depending on the weather conditions in your area and the product you use, you’ll need to recoat the wood every 2–5 years. Synthetic and composite decking products don’t require any type of paint or sealer and only need to be cleaned regularly to prevent staining.

Question 4

How long will my new deck last?

Accepted Answer

Proper maintenance is key to the longevity of your new deck. With good care and prompt repair of any damage, most decks can last 20 years or more. The materials you choose for your deck and its level of exposure to the elements can affect how long the structure and surface will last.

Question 5

How much does it cost to build a deck?

Accepted Answer

The cost of building a deck varies depending on its intended purpose, size, style and material, as well as your location. A simple deck built with basic, pressure treated wood could cost just $12 to $15 per square foot. Upgrading to composite or higher-end wood decking or adding features like stairs, custom railings, seating and multiple levels can raise the price to $35 or more per square foot.

For some projects, the cost per square foot goes down as the scale of the job goes up, but when it comes to a structural job like building a deck, expenses may increase all around. A more substantial foundation, larger beams and additional posts needed to support a bigger structure can price the job in a higher bracket. Careful planning with your pro will help ensure you get a deck that provides the space and features you need at a price that fits your budget.

Question 6

How long will it take to build a deck?

Accepted Answer

Most small decks can be built within a few days. Building the foundation and framing for a large deck or a deck around a pool can take much longer. Depending on its complexity, completing the foundation, framing, stairs, decking, and railings for your project may take a week or more. If your deck needs to be painted or stained after it’s built, you should plan for a few extra days to apply and dry the finish.

Question 7

Should I hire a pro to build my deck?

Accepted Answer

Deck construction requires careful planning to ensure structural integrity and safety. In addition, many cities require a permit for deck building. An experienced pro can ensure your deck’s foundation is solid, its structure is sound, and that stairs and deck railings are secure. When you hire a pro, you can rest assured they will have the knowledge and equipment to build a deck that is beautiful, functional and safe.

Question 8

Do I need a permit to build a deck?

Accepted Answer

Before getting started with your project, contact your local building authority to see if you will need a permit to build, repair or replace your deck. Once you’re ready to move forward, your pro should be able to help you pull any permits that are required.
