Materials Needed

Before you begin building a deck over your concrete porch, make sure you have all the necessary materials on hand. Here’s a list of what you’ll need:

• Pressure-treated lumber: This will serve as the framework for your deck. Make sure to choose lumber that is suitable for outdoor use and resistant to rot and decay.
• Concrete screws or anchors: These will be used to secure the sleepers to the concrete porch.
• Decking boards: Select high-quality decking boards that are durable and will withstand the elements. You can choose from a variety of materials, such as wood, composite, or PVC.
• Joist hangers and nails: These will be used to secure the sleepers to the framework.
• Concrete sealer: Before installing the sleepers, apply a concrete sealer to protect the porch from moisture damage.
• Drill and circular saw: These tools will be essential for cutting and assembling the materials.
• Tape measure, level, and other basic hand tools: These tools will help you with accurate measurements and ensuring a level deck.
• Safety gear: Don’t forget to wear safety goggles, gloves, and a dust mask when working with power tools and materials.

It’s important to gather all the materials before starting the project to minimize interruptions and ensure a smooth construction process. If needed, you can consult with a local hardware store or home improvement center for expert advice on selecting the best materials for your project.

Step 1: Measure and Plan

The first step in building a deck over a concrete porch is to carefully measure the area and create a detailed plan. This will help you determine the size and layout of the deck, as well as the quantity of materials needed.

Start by measuring the dimensions of your concrete porch. Use a tape measure to determine the length, width, and height of the porch. This will provide you with the basic measurements for planning the deck.

Next, consider how you want the deck to be positioned on the porch. Think about factors such as sunlight exposure, privacy, and access to your home. Take note of any existing features or obstacles, such as columns or doorways, that may affect the design and layout of the deck.

Once you have the measurements and layout in mind, it’s time to create a detailed plan. Consider the size and shape of the deck, as well as any desired features, such as stairs or railings. Sketch out the plan on paper or use a digital design tool to visualize the final result.

When planning your deck, it’s important to comply with any local building codes and regulations. Check with your local building department to find out if you need a permit for your project and to ensure that your deck meets the necessary safety requirements.

By taking the time to measure and plan your deck, you’ll be able to create a well-designed and functional outdoor space that perfectly suits your needs and enhances the overall aesthetic of your home.

Step 2: Prepare the Concrete Porch

Before you can build a deck over your concrete porch, it’s important to prepare the surface properly. Follow these steps to ensure a solid foundation for your deck:

1. Clean the porch: Start by thoroughly cleaning the concrete surface. Remove any dirt, debris, or grease using a stiff brush and a mild detergent. Rinse the porch with water and allow it to dry completely.
2. Repair any cracks: Inspect the concrete for any cracks or damage. Use a concrete patching compound to fill in any cracks or holes in the surface. Allow the compound to dry according to the manufacturer’s instructions.
3. Apply a concrete sealer: Once the repairs are complete, apply a concrete sealer to protect the porch from moisture. Follow the instructions on the sealer to ensure proper application. Allow the sealer to dry completely before moving on to the next step.

Preparing the concrete porch is essential to ensure that it can withstand the weight and pressure of the deck. By cleaning, repairing, and sealing the surface, you’ll create a strong and stable foundation for your new outdoor space.

Before building a deck over a concrete porch, make sure the concrete is in good condition and level. Use pressure-treated lumber for the frame and composite decking for durability. Install proper drainage to prevent water buildup.

Step 3: Install the Sleepers

Once the concrete porch is properly prepared, it’s time to install the sleepers, which will serve as the base for your deck. Follow these steps to install the sleepers:

1. Measure and mark: Use a tape measure and a pencil to mark the locations where the sleepers will be placed. Typically, sleepers are spaced every 16 inches for optimal support.
2. Drill pilot holes: Using a drill and a masonry bit, drill pilot holes into the concrete at each marked location. Make sure the holes are deep enough to accommodate the concrete screws or anchors that will be used to secure the sleepers.
3. Attach the sleepers: Place the sleepers on the concrete, aligning them with the pilot holes. Use concrete screws or anchors to secure the sleepers to the porch. Make sure they are level and securely attached.
4. Add joist hangers: Install joist hangers on the sleepers using nails or screws. These will provide additional support for the decking boards.
5. Check for level: Use a level to ensure that the sleepers are perfectly level. Make any necessary adjustments by adding shims under the sleepers.

Installing the sleepers is a crucial step in building an elevated deck over a concrete porch. It provides the necessary support and ensures that the deck is stable and structurally sound. Take your time during this step to ensure accuracy and proper installation.

Step 4: Attach the Decking Boards

With the sleepers in place, it’s time to attach the decking boards to complete the construction of your deck. Follow these steps to properly install the decking boards:

1. Choose the direction and pattern: Decide on the direction in which you want the decking boards to run. You can choose to run them parallel or perpendicular to the house, depending on your preference. Also, consider the pattern you want to create with the boards, such as staggered or herringbone.
2. Start at one end: Begin by placing the first decking board at one end of the deck, flush with the edge. Use decking screws to secure the board to the sleepers, making sure it is level and properly aligned.
3. Continue laying the boards: Place the next decking board next to the first one, leaving a small gap for expansion. Attach it to the sleepers using screws. Repeat this process until all the decking boards are laid across the entire deck.
4. Trim the boards: If necessary, trim the last board to fit the width of the deck. Measure carefully and use a circular saw to make the cut. Ensure that the trimmed board fits snugly in place.
5. Add finishing touches: Once all the boards are attached, go over the deck and make sure each board is securely fastened. Use a sander to smooth any rough edges or splinters. Consider adding railings, stairs, or other desired features to complete the look and functionality of your deck.

Attaching the decking boards is the final step in building your deck over a concrete porch. Take your time to ensure each board is properly aligned, attached, and level. By following these steps, you’ll create a beautiful and sturdy deck to enjoy for years to come.

Step 5: Add the Finishing Touches

Now that your deck is structurally complete, it’s time to add the finishing touches to enhance its appearance and functionality. Follow these steps to put the final touches on your deck:

1. Stain or paint: Consider staining or painting the decking boards to protect them from the elements and enhance their aesthetics. Choose a color that complements your home’s exterior and apply the stain or paint according to the manufacturer’s instructions.
2. Install railings: If desired, install railings around the edges of your deck for safety and aesthetics. Choose railings that match the style of your deck and follow the installation instructions provided by the manufacturer.
3. Add lighting: Install outdoor lighting to illuminate your deck and create a warm ambiance during the evenings. You can choose from various lighting options, such as solar-powered lights, string lights, or deck post lights.
4. Include seating and accessories: Furnish your deck with comfortable seating options, such as outdoor sofas, chairs, or a patio dining set. Add accessories like outdoor cushions, umbrellas, and planters to personalize and enhance your deck space.
5. Regular maintenance: Keep your deck in top condition by regularly cleaning it and performing necessary maintenance tasks. Sweep away debris, wash the boards with a mild detergent and water, and inspect for any signs of wear or damage. Replace any damaged boards or hardware as needed.

Adding the finishing touches to your deck will not only enhance its visual appeal but also improve its functionality and comfort. Take the time to carefully choose and install the right accessories, and remember to perform regular maintenance to ensure your deck remains a beautiful and enjoyable space for years to come.
