Beyond simply adding to your home’s value, building a deck can increase your quality of life dramatically, expanding your living space and giving your family more room to make precious memories. So, let’s learn how to build a deck!
Quick Answer
To build a deck, start by defining its purpose and design, then hire a licensed contractor to secure permits and prepare the site. The contractor will install footings, frame the structure, add decking, railings and stairs, and schedule final inspections before you enjoy your finished outdoor space.
In most cases, homeowners can expect the process to cost about $7,000–$10,000, depending on materials and size.

1. Define Your Deck’s Purpose and Style
Start by deciding what you want out of your deck. Are you looking for a space for outdoor dining, lounging, or a combination of both? Do you want it attached to your home or elevated in your yard, perhaps beside an above-ground pool?
Determine the style, size, purpose, and location that suits your needs and complements your home and yard’s layouts, allowing your contractor to better understand your vision.
Consider the following when planning your deck:
- How you’ll use the space (dining, lounging, entertaining)
- Whether it will attach to your home or stand alone
- The ideal location (sun exposure, privacy, view)
- Desired size and shape
- How it complements your home’s architecture
2. Research and Choose a Professional Contractor
Search for a reputable deck contractor in your area. Lucky for you, you’re on a qualified contractor’s website right now, and we’d love to use our 108 years of experience in the business to help you build your dream deck.
But, if you’d like to expand your search just to be safe, you can start with a simple Google search. Check contractors’ online reviews to ensure they’ll give you the quality of work you deserve, and take a look at what types of decks they install to be sure your needs will be met.
If you still haven’t found anything after going through this process, ask family and friends for recommendations. Out of everyone you know, there’s almost certainly someone who’s had a new deck installed and is happy with the result.
When comparing contractors, look for:
- Licensing and insurance
- A portfolio of completed projects
- Verified Google reviews
- Experience with your desired deck style and material
- Transparent pricing and detailed quotes
Obtain multiple quotes and select a contractor whose experience and pricing align with what you need.
3. Obtain Necessary Permits
In many areas, deck installations require permits. Check with your local building department to determine the specific permits needed. Your chosen contractor should be well-versed in local regulations, so they’ll assist you through this process.
4. Design and Plan Your Project
Work closely with your contractor to finalize the deck’s design and layout. Discuss which materials you want to use among the available options, such as wood, composite, PVC, and beyond. Also be sure to review any finishing details, such as railings and stairs. Of course, an experienced contractor can offer valuable insights to ensure your deck is both structurally sound and aesthetically pleasing, so this should not be a difficult task.
If you need help deciding which material to use, check out the table below. Note that higher upfront costs are often outweighed by lower maintenance costs in the long term, so you should consider how long you want to use your deck, along with which material will complement your home’s aesthetics, when making your decision.
| Material | Pros | Cons | Maintenance |
|---|---|---|---|
| Pressure-treated wood | Affordable, classic look | Can warp and rot over time | High (stain and seal regularly) |
| Composite | Low maintenance, long-lasting | Higher upfront cost | Low |
| PVC | Waterproof, extremely durable | Most expensive option | Very low |
5. Set a Project Timeline
Set a realistic project timeline with your contractor. Keep in mind that inclement weather and other unforeseen factors may affect this schedule, so be prepared to be flexible. Also ensure that this timeline includes milestones for inspections and approvals.
6. Develop a Cost Estimate
Your contractor should provide a detailed cost estimate, including labor, materials, permits, and any additional expenses like site preparation or demolition of an existing structure. The cost to build a deck varies widely based on materials, size, and location, but for an average-sized deck, you can expect to pay at least $7,000, or about $21 per square foot.

7. Prepare the Site
Before construction begins, the area where the deck will be installed should be properly prepared. This may involve clearing vegetation, leveling the ground, and ensuring proper drainage so your deck doesn’t suffer any structural damage from water. Check with your contractor about what they plan on doing to avoid any surprises during construction.
Pro Tip
Ask your contractor to walk you through their footing depth and framing plan before construction begins. This helps you confirm long-term structural durability.
8. Construct the Frame
Once the site is ready, the construction process can finally begin. Your contractor will start by installing the deck’s support structure, which typically consists of concrete footings and posts. Next, the framing and decking materials are installed. Pay attention to the craftsmanship (deep footings, proper support, etc.) to ensure your deck is built to last.
9. Apply the Finishing Touches
After the basic structure is complete, you can add on any finishing touches you had in mind. These may include:
- Railing (wood, metal, composite, or cable)
- Stairs and landings
- Built-in seating or benches
- Lighting
Quality finishing ensures both the safety and aesthetic appeal of your deck.
10. Obtain Inspections and Approvals
Local authorities may require inspections to verify that your deck complies with building codes. Work closely with your contractor to schedule and pass these inspections, allowing you to avoid any unnecessary delays.
11. Enjoy Your Deck!
Once your deck is complete, it’s time for you and your family to finally enjoy the project you’ve put so much work into! Of course, keep in mind that regular maintenance, like sealing or staining, will help prolong the life of your deck. In this way, with just a little effort, you can ensure your new deck stays in top-notch condition for decades to come.
Frequently Asked Questions (FAQs)
Start by measuring the height from the deck surface to the ground. Divide that number by 7 ¾ (the average riser height) to determine how many steps you’ll need. Cut stringers (the vertical boards connecting the treads) from quality lumber, then attach them securely to the deck frame and fasten treads (the horizontal boards you step on) using exterior-grade screws.
How do I build a deck on the ground level?
A ground-level deck typically doesn’t require traditional footings or posts. Instead, it rests on concrete deck blocks or gravel pads for drainage. Install a simple frame of pressure-treated lumber and add joists for support. Then, fasten your decking boards with corrosion-resistant screws. Because ground-level decks sit close to soil, proper moisture control is essential, especially in the hurricane-prone Carolinas. You can use moisture barriers and water-repellent sealants for this purpose.
How do I build deck railing?
To build safe and attractive deck railing, install posts first, anchoring them securely to the deck framing or rim joist. Then attach the top and bottom rails, ensuring the spacing meets local code (usually no more than 4 inches between balusters). You can use wood, composite, metal, or a variety of other materials depending on how much maintenance you’re willing to take on.
How much does it cost to build a deck?
The average cost to build a deck is around $7,000–$10,000 in total, or roughly $20–$40 per square foot, though these figures can rise dramatically for premium deck options. Wood decks are typically more affordable upfront, while composite or PVC options cost more but require less maintenance over time. Labor, permits, location, and add-ons like stairs or railings can also impact total cost.
How do I build a floating deck?
Like a ground-level deck, a floating deck is built directly on the ground rather than attached to your home, though it usually sits a bit higher from the soil than its ground-level counterpart. It uses concrete deck blocks or small footings to support a freestanding frame of pressure-treated joists. Because it “floats,” this type of deck can be easier and faster to build, but you’ll still need to ensure a level surface and proper drainage to prevent shifting or rot.
How do I build a gate for a deck?
To build a gate, frame two vertical and two horizontal boards to fit your railing opening, add diagonal bracing for strength, and fasten deck boards or pickets across the front. Use heavy-duty outdoor hinges and a latch rated for exterior use. Make sure the gate swings freely and aligns with your railing height for a clean and safe finish.
How do I build a cover over my deck?
You can build a deck cover using a pergola, an awning, or even a full roof extension. Start with strong posts anchored to the deck or foundation, then add beams and rafters according to your design. If you’re installing a roofed structure, flashing and waterproofing where it connects to the house are critical. Always confirm your plans with a licensed contractor or local inspector to meet code requirements, especially if you’ve opted for a roof extension.
Final Thoughts
With the help of a professional contractor, installing your new deck is an straightforward and stress-free project. It’s an investment in your family’s future, giving you the outdoor space you need to forge memories that will last a lifetime, all with just a little planning. So, if you make informed decisions, take your time during the planning phase, and choose a contractor you trust, you’ll be well on your way to your dream outdoor living area.
