Building a board-on-board fence offers a beautiful, durable, and private solution for your property. Unlike traditional fences, this style boasts double-sided boards for a polished look from both sides. This comprehensive guide walks you through each step, from planning to final touches.

Planning Your Board-on-Board Fence

Before you start digging, careful planning is crucial for a successful project.

1. Determine Fence Dimensions and Materials

Measure your property line: Accurately measure the length of your fence line. Consider any gates or curves.
Choose your wood: Pressure-treated lumber is essential for longevity and rot resistance. Cedar and redwood are attractive alternatives, but more expensive.
Calculate materials: Determine the number of posts, rails, and boards needed based on your measurements. Use an online fence calculator or consult a lumber yard for assistance.
Obtain necessary permits: Check with your local building department for any required permits before starting construction.

2. Design Considerations

Fence Height: Common heights are 4, 5, or 6 feet. Taller fences offer more privacy but require more materials.
Board Spacing: Consider the gap between boards for aesthetics and privacy. A smaller gap means more privacy but requires more boards.
Gate Placement: Plan the location and size of your gate(s) to ensure easy access.

Building Your Board-on-Board Fence: A Step-by-Step Guide

Now for the hands-on part! This detailed guide breaks down the construction process:

1. Setting Fence Posts

Dig Post Holes: Use a post hole digger to create holes deep enough (at least 1/3 of the post length) to ensure stability. The depth will depend on your soil type and local frost line.
Set Posts: Place posts in the holes, ensuring they are plumb (perfectly vertical) using a level.
Fill Holes with Concrete: Mix concrete according to package instructions and fill the holes around the posts, ensuring proper support. Allow concrete to fully cure.

2. Attaching Rails

Attach Rails to Posts: Once the concrete is set, attach the horizontal rails to the posts using galvanized lag screws. Ensure the rails are level and evenly spaced. For a stronger fence, consider using more than two rails.
Measure and Cut Rails: Use a measuring tape and saw to cut rails to the exact length needed between each post.

3. Attaching the Boards

First Layer of Boards: Attach the first layer of boards to the rails, starting from the bottom. Use galvanized nails or screws, ensuring the boards are flush with each other. Overlap joints for strength.
Second Layer of Boards: Attach the second layer of boards over the gaps left by the first layer. This creates the board-on-board effect, enhancing privacy and aesthetics. Make sure the gaps align for a uniform look.
Consider Board Orientation: Stagger the ends of the boards to create a more aesthetically pleasing pattern, and to avoid weak points.

4. Finishing Touches

Install Gate: If you're incorporating a gate, follow the manufacturer's instructions for installation.
Caulk Gaps: Seal any gaps between boards and posts with exterior-grade caulk to prevent water damage.
Stain or Seal: Apply a wood stain or sealant to protect the fence from the elements and enhance its appearance. Choose a product suitable for outdoor use.

Tips for Success

Use quality materials: Investing in high-quality lumber and fasteners will ensure your fence's longevity.
Work with a partner: Building a fence is easier with a helper.
Check measurements frequently: Ensure everything is level and square throughout the process.
Safety first: Wear appropriate safety gear, including safety glasses and work gloves.

Building a board-on-board fence is a rewarding project that adds value and beauty to your property. By following these steps and tips, you can create a lasting and attractive addition to your home. Remember to always prioritize safety and take your time to ensure accuracy. With patience and attention to detail, you'll have a stunning new fence in no time!
