Guide to Mounting Your 55" TV on an Exterior Wall

Mounting a TV on an exterior wall can transform your outdoor space into an entertainment hub, perfect for watching movies, sports, or streaming your favorite shows while enjoying the fresh air. However, doing this correctly is essential to ensure the TV is securely mounted and protected from the elements. I’ve done several DIY projects like this, and here’s a step-by-step guide based on my experience and some helpful advice from the DIY community.

Why Mount a TV Outside?

Mounting a TV on an exterior wall or deck provides the flexibility to enjoy your favorite content while relaxing outdoors. Whether it’s for a cozy movie night under the stars or watching a game with friends during a barbecue, an outdoor TV setup adds value to your outdoor living space. However, unlike mounting a TV indoors, there are unique considerations when installing one outside, such as weather protection, secure mounting, and choosing the right spot.

Choosing the Right Spot

Before diving into the technical aspects, the first step is deciding on the best location for your TV. Consider the following factors:

Visibility and Viewing Angle: Make sure the TV is easily viewable from your seating area. Avoid mounting it too high or too low for optimal viewing comfort.
Protection from Elements: Choose a location that is shielded from direct sunlight, rain, and wind. If possible, mount it under a covered patio or porch. This will extend the life of your TV and reduce glare on the screen.
Proximity to Power and Connectivity: Ensure the TV is close to a power outlet and has easy access to cable or satellite connections or a strong Wi-Fi signal for smart TVs.

Tools and Materials Needed

To mount a 55” TV on an exterior wall, you’ll need several tools and materials. Here’s what I recommend based on my own experience and tips from the DIY community:

Stud Finder: Essential for locating studs within the wall to secure the TV mount.
Drill and Drill Bits: A power drill with the right-sized drill bits for pilot holes and screws.
Lag Screws and Anchors: Strong lag screws are crucial for securing the mount to the studs.
Level: To ensure the mount is perfectly horizontal.
Outdoor TV Mount: Ensure it’s rated for outdoor use, especially if you live in an area with extreme weather conditions.
Siding Blocks: These help to mount the TV securely if your exterior wall is covered in siding.
Weatherproof Box or Cover for Cables: Protects the connections from rain and moisture.

Step-by-Step Guide to Mounting Your TV

Step 1: Locate the Studs

Finding the studs is crucial for a secure installation. While interior walls typically have visible or easy-to-locate studs, exterior walls, especially those with siding, require extra attention.

Use a stud finder to locate the studs on the exterior wall. Make sure to mark them clearly.
Double-check the location by knocking on the wall; a hollow sound indicates you’re not on a stud, while a solid sound confirms it.

Step 2: Prepare the Mounting Area

Once the studs are located, it’s time to prepare the mounting area. If your exterior wall is covered with siding, using siding blocks can provide a sturdy surface for mounting.

Cut a Siding Block: If you’re mounting on siding, consider cutting out a section and replacing it with a sturdy backing like plywood, as suggested by a DIYer who installed a 55” TV on their porch.
Install the Block with J Channel: Use a J channel to surround the block for a clean finish. Ensure that the block is firmly attached to the wall and the siding is sealed to prevent water ingress.

Step 3: Drill Pilot Holes

Drilling pilot holes prevents the wood from splitting and ensures the screws go in straight.

Hold the TV mount bracket against the wall in the desired position.
Use a pencil to mark the points where you’ll drill into the studs.
Drill pilot holes using a drill bit slightly smaller than the diameter of your screws.

Step 4: Attach the Mount to the Wall

With the pilot holes ready, it’s time to secure the mount.

Position the mount over the pilot holes and drive lag screws into the studs. Make sure the mount is level before fully tightening the screws.
If using anchors, insert them into the drilled holes before driving in the screws.

Step 5: Mount the TV

Mounting the TV itself is the final step, but it requires precision to avoid any mishaps.

Attach the mounting bracket to the back of the TV. Ensure it’s compatible with the outdoor-rated mount you’ve chosen.
Lift the TV and carefully place it onto the wall mount. Make sure it locks securely into place.
Check that the TV is level and securely fastened.

Step 6: Manage Cables and Protect Connections

Outdoor conditions can quickly deteriorate cables and connectors. Therefore, protecting them is key.

Run Cables Through a Weatherproof Box: Use a weatherproof box to keep connections dry.
Use Cable Clips and Zip Ties: Secure cables neatly along the wall to prevent them from being tugged or exposed to elements.

Additional Tips for a Successful Installation

Consider an Outdoor TV: Standard TVs aren’t designed to withstand outdoor conditions. Outdoor-rated TVs have special coatings and are sealed against moisture.
Use a Protective Cover: Even if your TV is under a covered porch, a protective cover can add extra protection when the TV is not in use.
Be Mindful of Temperature Changes: Electronics can be sensitive to extreme temperatures. If you live in an area with significant seasonal changes, consider bringing the TV inside during off-seasons.

Enjoy Your Outdoor Viewing Experience

Mounting a TV on an exterior wall opens up a world of outdoor entertainment possibilities. Whether it’s for family movie nights, a summer barbecue, or watching sports with friends, the key is to ensure a secure and weather-protected installation. With the right tools, preparation, and a bit of DIY know-how, you can create a fantastic outdoor viewing experience that will be the envy of your neighborhood.

By following these steps and tips from seasoned DIY enthusiasts, you can confidently mount your 55” TV on an exterior wall, ensuring it remains secure, functional, and protected from the elements. Enjoy your new outdoor setup!

FAQ: Mounting a 55" TV on an Exterior Wall

This FAQ section provides answers to common questions about mounting a 55” TV on an exterior wall, focusing on practical tips, troubleshooting advice, and specific scenarios that may arise during the installation process.

What if I can't find a stud where I want to mount my TV?

If there isn't a stud exactly where you want to mount your TV, you have a few options:

Use a Mounting Plate: Install a piece of plywood or a mounting plate that spans the distance between two studs. This will provide a stable surface to attach the TV mount.
Wall Anchors: Heavy-duty wall anchors can be used if you must mount the TV in a specific spot without a stud. However, this method is less secure, especially for larger TVs.

Can I mount a TV on siding?

Yes, you can mount a TV on siding, but you need to take extra steps to ensure stability and weather protection:
