How to Build a Deck for DIYers in 5 Easy Steps

Comprehensive Guide to Building Your Own Deck

Building a deck is a complicated process and not just a simple weekend project. New Jersey’s top deck builder, Deck Guardian, has been designing and constructing decks for over 10 years. We’ve seen almost every deck challenge and have perfected the process of building a deck that stays strong and beautiful for decades.

Hiring professional deck builders is the best best to get a solid, safe,  and secure deck built. However, there are some times when a DIYer may want to tackle the job themselves. So, we’ve taken our best tips and compiled them into this blog post on how to build a deck for DIYers.

Step 1: Come Up With A Deck Plan

Planning is the key to a great deck. It’s not as fun as building, but it’s an important step that can’t be rushed. Here’s what you need to do:

• Choose the Right Location: Pick a spot that makes sense for your home. Think about sun, shade, and views. Also, check for underground pipes or wires. You don’t want to dig into those!
• Get a Plan Designed and Approved: A good plan is like a roadmap for your deck. It shows you what to do at each step. An engineer can make sure your deck will be safe and strong. They know all about weight limits and support beams.
• Permits and Regulations: Every town has rules about decks. You need to follow these rules. Get all the right permits before you start building. It might seem like a pain, but it’s way better than having to tear down your deck later!

At Deck Guardian, we always start with a solid plan. It saves headaches down the road. Take your time with this step. A good plan makes the rest of the job much easier.

Step 2: Gather Your Materials and Tools

Before you start your deck construction project, you need to get everything ready. If you forget something, it can slow down your whole project. Here’s what you need to do:

• Make a list of all the materials you’ll need
• Don’t forget about the small stuff like nails and screws
• Get the right tools for the job
• Rent any big tools you don’t own

Having everything on hand before you start will make your DIY deck building go much smoother. It’s no fun to stop in the middle of your work because you’re missing something. At Deck Guardian, we always make sure we have all our supplies ready before we begin. This saves time and keeps the project moving forward.

Remember, good quality materials are key to a long-lasting deck. Cheap stuff might save you money now, but it could cost you more in the long run. We’ve seen decks fall apart way too soon because of low-quality materials. Don’t let that happen to your deck.

Step 3: Step-by-Step Construction Guide

Now that you have your plan in place, it’s time to start DIY deck building. This guide will walk you through the major stages of deck construction.

Prepare the Site

Begin by clearing the area where your deck will be built. Remove any vegetation, rocks, and debris. Then, using stakes and string, outline the deck’s perimeter according to your plan.

Ensure the ground is level using a transit level or laser level. If necessary, excavate to create a level surface or to accommodate for slope. Proper site preparation is crucial for the stability and longevity of your deck.

Install the Foundation

The foundation is critical for your deck’s structural integrity. Most decks use concrete footings or piers to support the main beams. At Deck Guardian, we use metal footings, which can be installed in any type of ground soil, are extremely strong, and don’t make a mess. However, these footings require specialized equipment to install and are not recommended for a DIY deck.

For DIY deck building, dig holes for your footings to the depth specified by local building codes, typically below the frost line. Place cardboard forms in the holes and fill them with concrete. Insert J-bolts or post anchors into the wet concrete. Allow the concrete to cure fully before proceeding.

Frame the Deck

Start by attaching a ledger board to your house, ensuring it’s level and properly flashed to prevent water damage. Install your posts, beams, and joists according to your plan.

Use joist hangers and metal connectors to ensure secure connections. Double-check that your framing is square and level at multiple points during this process. Proper framing is essential for a stable deck and even decking installation.

Lay the Decking Boards

Begin laying your decking boards perpendicular to the joists. Start at the edge of the deck furthest from the house, leaving a small gap (about 1/8 inch) between boards for drainage and expansion.

Use spacers to maintain consistent gaps. Secure each board with two screws at every joist crossing. Stagger the board ends across at least three joists for a stronger, more appealing look.

Install Railings and Stairs

If your deck is more than 30 inches off the ground, railings are typically required by code. Install posts for your railings, ensuring they’re securely attached to the framing. Attach top and bottom rails, then add balusters according to code requirements.

For stairs, calculate the rise and run carefully to ensure comfortable, safe steps. Build stringers, attach treads and risers, and don’t forget to add handrails as required by local building codes.

At Deck Guardian, we emphasize the importance of following each of these steps meticulously. Proper execution at each stage ensures a safe and durable deck that will serve you well for years to come.  If at any point you feel overwhelmed, it’s wise to consult with or hire a professional deck contractor, like Deck Guardian, to ensure the job is done correctly and safely.

Step 4: Apply the Finishing Touches

If you’ve built a wood deck, you should apply a protective stain or finish. Start by sanding any rough spots on your deck. Apply a high-quality water-repellent sealer or stain to protect the wood from moisture and UV damage.

Choose a product compatible with your decking material. Apply evenly, following the wood grain, and allow proper drying time between coats.

Incorporate lighting for safety and ambiance. Consider installing post cap lights, stair riser lights, or recessed deck lights. Ensure all electrical work complies with local codes and consider hiring a licensed electrician for complex installations.

Once construction is complete, personalize your space with deck furniture, planters, and deck accessories. Choose weather-resistant items designed for outdoor use.

Step 5: Maintenance Tips for DIY Deck Building

To keep your DIY deck in top condition, it’s important to understand what’s needed for regular maintenance. Here are some deck building tips to ensure a long-lasting deck:

• Clean your deck annually with an appropriate deck cleaner
• Inspect regularly for loose boards, protruding nails, or signs of rot
• Reapply sealer or stain every 2-3 years or as needed
• Keep the deck clear of leaves and debris to prevent moisture buildup
• Trim nearby vegetation to reduce shade and moisture on the deck
