How To Build A Deck

Materials you will need:

  1. Pressure-treated lumber boards (2x6 or 2x8)
  2. Concrete footings or deck blocks
  3. Post anchors or post brackets
  4. Galvanized deck screws or nails
  5. Joist hangers
  6. Ledger board
  7. Post caps
  8. Waterproofing membrane
  9. Flashing
  10. Concrete mix (if using footings)
  11. Gravel
  12. Level
  13. Tape measure
  14. Drill
  15. Circular saw
  16. Hammer
  17. Safety glasses
  18. Work gloves
  19. Carpenter's square

Step 1: Planning and Preparation

  1. Obtain any necessary permits or permissions from your local building authority.
  2. Determine the size and location of your deck, ensuring it adheres to local building codes and regulations.
  3. Clear the area where the deck will be built, removing any vegetation, rocks, or debris.
  4. Mark the perimeter of the deck using stakes and string.

Step 2: Digging Footings (if applicable)

  1. Consult local building codes to determine the required depth and diameter for your footings.
  2. Use a post hole digger to dig holes at the marked locations for your footings.
  3. Place a few inches of gravel in the bottom of each hole for drainage.
  4. Mix concrete according to the manufacturer's instructions and pour it into each hole.
  5. Smooth the concrete surface and let it cure for the recommended time.

Step 3: Attaching the Ledger Board

  1. Locate the ledger board, which will be attached to the house.
  2. Measure and mark the height of the deck on the house wall.
  3. Use a level and a straight edge to draw a level line at the marked height.
  4. Attach the ledger board to the house wall using lag screws or through-bolts, making sure it is level and securely fastened.
  5. Install flashing over the top of the ledger board to prevent water penetration.

Step 4: Installing Posts and Beams

  1. Measure and cut the posts to the desired height, accounting for the thickness of the deck boards and any slope you want.
  2. Attach post anchors or post brackets to the footings or the concrete patio.
  3. Place the posts into the anchors or brackets and secure them with appropriate hardware.
  4. Install beams parallel to the house, attaching them to the posts with appropriate connectors.
  5. Use a level to ensure the posts and beams are plumb and level.

Step 5: Installing Joists

  1. Measure and cut pressure-treated lumber boards to serve as joists.
  2. Attach joist hangers to the inside face of the ledger board at regular intervals.
  3. Place the joists into the joist hangers and secure them with appropriate hardware.
  4. Ensure the joists are evenly spaced and level.

Step 6: Installing Deck Boards

  1. Start at one end of the deck and begin laying the deck boards perpendicular to the joists.
  2. Leave a small gap (about 1/8 inch) between each board for expansion and drainage.
  3. Secure each board with two screws or nails at each joist, countersinking the fasteners slightly.
  4. Continue installing deck boards until you reach the other end of the deck.
  5. Trim the last board, if necessary, to fit the width of the deck.

Step 7: Finishing Touches

  1. Attach post caps to the top of each post for a finished look.
  2. Apply a waterproofing membrane to the top surface of the deck boards to protect against moisture.
  3. Install any additional railing or balusters according to local building codes and personal preference.
  4. Stain or paint the deck boards and any other exposed wood surfaces to protect them from the elements.
  5. Install any desired accessories such as built-in seating, planter boxes, or lighting fixtures.

Step 8: Safety Checks

  1. Double-check all connections and hardware to ensure they are secure.
  2. Inspect the deck for any sharp edges, protruding screws, or potential hazards.
  3. Make sure all railings are sturdy and meet the required height regulations.
  4. Test the stability of the deck by applying pressure to different areas.

Step 9: Final Inspections

  1. Contact your local building authority to schedule a final inspection if required.
  2. Ensure that your deck meets all building codes and regulations before use.

Step 10: Deck Maintenance

  1. Regularly inspect the deck for any signs of damage, rot, or decay.
  2. Clean the deck periodically using a mild detergent and a scrub brush or pressure washer.
  3. Apply a protective sealant or stain every few years to maintain the appearance and durability of the wood.

Remember, building a deck can involve complex construction techniques and safety considerations. It's always recommended to consult with a professional or experienced builder if you're unsure about any aspect of the process. Safety should be a top priority throughout the construction and use of your deck.
