How do you build a privacy fence around a deck?

Adding a privacy fence around your deck is a great way to increase your outdoor living space by providing more privacy, blocking unwanted views, and protecting your deck from wind. Depending on the size and layout of your deck, there are a few options for adding a privacy fence – you can attach the fence directly to the deck perimeter, build a freestanding fence around the deck, or a combination of both. Planning properly and using the right materials will ensure your new privacy fence blends well with your deck and backyard.

Things to Consider Before Building a Privacy Fence Around a Deck

Here are some important factors to think through before starting on your project:

• Size and layout of deck – Measure the perimeter of your deck to calculate how much fencing you need. Consider any nearby trees, slopes or property lines that may impact placement.
• Type of fence – Think about whether you want a semi-private lattice fence, a solid privacy fence, or a combination style. This depends on your privacy needs and aesthetic preferences.
• Fence height – Standard privacy fence height is 6 feet, but you may want to go taller depending on your needs. Check local regulations for maximum allowed heights.
• Gate location – Decide if you want gates to access the yard from your deck, and where they should be placed.
• Post spacing – For privacy fences, post spacing is typically 8 feet on-center. But a freestanding fence around a deck may need posts spaced more closely for rigidity.
• Wind load – Consider your climate and exposure to determine if the fence needs additional bracing to withstand wind gusts.
• Material choices – Pressure-treated wood is common, but composite, PVC, or metal fencing are also options. Choosematerials suited to your climate that complement your deck.
• Zoning laws – Be sure to check local zoning regulations for any restrictions on fence height, materials, and placement on your property.
• HOA requirements – If you belong to a homeowner’s association, ensure your fencing plans meet any covenants or requirements.

Tools and Materials Checklist

Once you’ve worked through the planning and considerations, here are the basic tools and materials you will need:

• Post hole digger
• Shovel
• Circular saw or miter saw
• Power drill and screws
• Cement or fast-setting concrete
• 6×6 pressure-treated posts
• 2×4 or composite boards for fence pickets
• Deck screws and galvanized nails
• Exterior wood stain or sealant (if using wood fence)
• Gate hinges and hardware
• Eye and ear protection
• Work gloves

Additional tools like a levels, clamps, and a nail gun can speed up the building process and make construction easier. Having the right materials on hand will allow your project to move efficiently from start to finish.

How to Attach a Privacy Fence to a Deck

If your deck perimeter has enough support from the existing frame, attaching fencing directly to the deck boards is the most seamless option. Here are the steps:

1. Mark out where the posts will go – they should be spaced about 8 feet apart. Dig post holes down past the frost line in your region (typically 2-3 feet).
2. Set 6×6 pressure-treated posts in the holes, plumb with a level. Pour concrete around posts and allow to set completely before moving on.
3. Measure the distance between posts and cut 2×4 or composite boards to length. Treated lumber or PVC boards work well to match the deck.
4. Pre-drill and screw pickets to the interior side of deck joists, sinking screw heads so they don’t snag feet or furniture. Allow a 1-2 inch gap between boards for airflow.
5. Secure post caps to the top of each post once all pickets are in place. Install gate hinges and hardware if adding a gate.
6. Stain or seal all lumber to protect it from weather and prevent rotting. Caulk around all seams to prevent water intrusion.

Attaching fence pickets directly to deck boards creates a clean, seamless look. Be sure the deck frame is sturdy enough to hold the weight and wind load before utilizing this fencing method.

Building a Freestanding Fence Around a Deck

For decks that can’t support attached fencing due to the frame construction, building a freestanding perimeter fence is the way to go:

1. Dig post holes around the perimeter of the deck, spacing posts 6-8 feet apart. Holes should be well below frost line, at least 2-3 feet.
2. Set 6×6 posts plumb in the holes and pour concrete to hold them in place. Let concrete fully cure before moving on.
3. Measure distance between posts and cut crossbeams to length from pressure-treated 2×4 lumber. Screw beams to posts.
4. Attach 2×4 or composite pickets to crossbeams with galvanized nails or exterior deck screws. Allow small gaps between pickets for airflow.
5. Brace end posts and gate posts for extra stability. Use post caps to create a finished look.
6. Add gate hinges and hardware if including a gate. Consider adding a gate across any stairs leading down from the deck.
7. Seal or stain all wood to protect from weathering. Caulk around beams and pickets.

Freestanding fencing requires a bit more work, but provides sturdy, customizable privacy around a deck. Pressure-treated lumber ensures it will stand up to the elements for years.

Fence Designs and Material Options

Beyond basic wooden privacy fences, there are a number of options to suit your deck style, budget and privacy needs:

Semi-Private Lattice Fencing

Lattice fencing features a crisscross board pattern that provides some privacy while still allowing airflow and filtered views. It can be attached directly to deck framing or posts set a foot or so off the deck perimeter. Durable composite or PVC lattice panels are low-maintenance options.

Picket Fencing with Planter Boxes

Alternating sections of fencing with built-in planter boxes create visual interest and privacy. Planter boxes integrated into the fence line are easy to maintain and water. You can plant trailing flowers, grasses or shrubs in the boxes.

PVC or Composite Fencing

For a maintenance-free fencing choice that won’t rot or need repainting, PVC or composite fencing is a great option. Many styles mimic wood privacy fencing but are molded from durable plastic or a wood-plastic composite. More expensive up front, but will last for decades.

Ornamental Metal Fencing

Wrought iron, aluminum or powder-coated steel fencing lends an elegant, decorative look to a deck. Standard designs provide some privacy while still allowing views and airflow. Durable and long-lasting, but generally a more expensive choice.

Cable Railings

Cable railing kits can invisibly outline a deck perimeter while offering a contemporary vibe. Cables are stretched taut between posts and can be paired with a minimal top rail. Provides only minimal privacy, but very discreet and stylish.

Wind and Weather Considerations

When installing fencing around a deck, it’s important to account for wind load and general weather resistance:

• Brace corner posts and gate posts with diagonal cross-bracing for stability
• Use metal post anchors below the frost line to reinforce freestanding posts
• Space freestanding fence posts closer together – around 6 feet on-center
• Utilize screws and adhesives rated for pressure-treated lumber
• Allow small gaps between fence boards for wind to pass through
• Use weather-resistant PVC, composite or metal fencing in very windy regions
• Seal all wood with water-repellent stain or sealant
• Caulk around all intersections and seams to prevent moisture intrusion

Proper installation techniques like these will result in fencing that can withstand wind, rain and other weather conditions for years to come.

Conclusion

Adding new privacy fencing around your backyard deck can help you get the most enjoyment out of your outdoor living space. With the right planning and materials, you can create durable, attractive fencing that blocks unwanted views and complements your deck design. Pay close attention to structural considerations like footings, post spacing and bracing. And be sure to check local regulations before constructing deck fencing. In no time you’ll be enjoying a more secluded, peaceful oasis right outside your home.
