Introduction
If your backyard feels too exposed or your current fence doesn’t block noise and neighbors, it may be time to learn how to build a double fence for extra privacy. A double fence consists of two parallel fences installed a short distance apart, creating a barrier that’s stronger, more private, and more visually appealing than a single row of boards or panels. While it requires more effort than a standard fence, the results are well worth it for homeowners who want both peace and privacy.
Why a Double Fence Matters for Privacy
A double fence goes beyond the traditional approach, offering benefits that a single fence often can’t provide:
- Maximum privacy: With no gaps between boards or panels, double fencing eliminates sight lines from neighbors.
- Noise reduction: The space between two fences helps absorb sound, making it ideal for properties near roads or noisy areas.
- Stronger barrier: Two layers of fencing provide extra durability against weather, wind, and wear.
- Design flexibility: You can create unique looks—such as staggered panels, horizontal vs. vertical layouts, or spaces filled with plants.
- Property value: A premium privacy fence enhances the appeal and value of your home.
By choosing a double fence, you’re investing in both security and comfort for your outdoor space.
Step-by-Step Guide to Building a Double Fence
Step 1: Plan and Measure the Fence Area
Decide where the double fence will go. Mark the boundary with stakes and string. Measure the total length and determine how far apart the two fences will be—typically 1 to 3 feet. This spacing provides privacy while still leaving room for maintenance.
Tip: Check property lines before building. You don’t want disputes with neighbors later.
Step 2: Gather Tools and Materials
You’ll need:
- Pressure-treated wood posts (4×4 or 6×6)
- Rails and pickets or pre-made panels
- Concrete and gravel for posts
- Nails, screws, or brackets
- Level, tape measure, and string line
- Circular saw or handsaw
- Protective gloves and safety gear
Step 3: Check Local Codes and HOA Rules
Many areas regulate fence height, placement, and style. Some may restrict double fences or require permits. Always confirm before digging post holes.
Step 4: Install the First Fence Line
Begin with the first row of posts:
- Dig holes 2–3 feet deep and about 8 feet apart.
- Place posts upright with gravel at the bottom for drainage.
- Fill with concrete and ensure posts are plumb.
- Let the concrete cure before attaching rails and pickets.
Add rails between posts and secure pickets vertically (or panels if using pre-built sections). This creates your first fence.
Step 5: Install the Second Fence Line
Repeat the process for the second fence row, parallel to the first. Keep the spacing consistent along the entire run. Use the same height for both fences unless you want a staggered effect.
Pro Tip: For a creative look, you can alternate picket placement—solid on the first fence, spaced slightly on the second—to create airflow while maintaining privacy.
Step 6: Secure and Align Both Fences
Use a level and string line to keep both fences straight and aligned. Ensure the spacing is even from start to finish. A consistent gap between fences gives a professional appearance.
Step 7: Optional Enhancements
- Fill the gap with plants: Add climbing vines, shrubs, or decorative elements between fences.
- Add soundproofing: Install outdoor acoustic panels or dense shrubs for better noise control.
- Stagger heights: Build the second fence slightly taller for extra coverage.
Common Mistakes to Avoid
- Mistake: Building too close to property lines.
Solution: Always double-check boundary markers and follow setback requirements. - Mistake: Using shallow post holes.
Solution: Dig at least 1/3 of the post length (24–36 inches) and set posts in concrete. - Mistake: Uneven spacing between fences.
Solution: Use a consistent guide (string line or temporary spacer boards) to maintain an even gap. - Mistake: Choosing weak materials.
Solution: Double fences put more weight on posts—use pressure-treated lumber and heavy-duty hardware. - Mistake: Forgetting maintenance access.
Solution: Leave enough space between fences to mow, stain, or repair without difficulty.
Extra Fence Tips & Hacks
- Add lattice tops: Decorative lattice on one or both fences adds height and elegance without feeling too closed in.
- Install solar lights: Mounting lights on posts enhances security and nighttime ambiance.
- Go for mixed materials: Pair wood with metal or vinyl for a unique design and longer-lasting structure.

Conclusion
Learning how to build a double fence for extra privacy is a worthwhile project for any homeowner who values comfort, peace, and security. By carefully planning, using strong materials, and ensuring proper spacing, you’ll create a durable fence system that blocks views, reduces noise, and looks stunning.
Pro Tip: Treat or stain wood before installation to protect against rot—doing it beforehand covers every surface and extends the life of your fence.
