Worked case: a 55-inch outdoor TV on a stucco patio wall under the roof — sun, hardware and the price range

The scenario

Picture a single-story ranch house from the early 1960s in a hillside-edge neighborhood, with a covered patio added along the back wall. The patio has a wood-beam roof, a stucco rear wall of the house and a low block planter along one side. The back wall faces southwest, so in summer the late afternoon sun reaches the patio from the side.

The household wants a 55-inch outdoor TV on the stucco wall, visible from an outdoor sofa. An existing outlet with a weather-resistant cover and GFCI protection sits just under the roof edge near the sliding door, which is exactly where the cable would want to go.

The wall is stucco over wood framing, with building paper and lath behind the finish. The question is not whether the TV can go there but where on the wall it escapes the sun and the splash from the sprinkler, and what holds it.

What the job involves

1. The household's patio is observed at the hours it is used, and the installer notes where the sun lands on the wall. The position is chosen for shade first and for the view second.
2. A scan and a probe hole identify the studs behind the stucco and the lath, and a small hole shows how thick the finish is.
3. Pilot holes are drilled through the stucco into the studs, and each hole is cleaned and sealed around the stainless lag bolt with a flexible sealant, so water cannot follow the bolt into the wall.
4. The outdoor-rated mount goes on with a level, and the TV is lifted into place by two people and locked with its safety screw.
5. The cables run in a protected raceway rated for outdoors, with a drip loop so water follows the cord down and away from the connector.
6. The TV is plugged into the outlet that already has a weather-resistant cover and GFCI protection.

Hardware and materials

• Outdoor-rated mount supplied, with coated or stainless parts
• Stainless lag bolts, sealant and washers for a sealed entry
• Hammer drill, masonry and wood bits
• Level, laser line, stud finder, probe bit
• Outdoor-rated raceway and cable clips

Add-ons often paired with this job

• Full-motion (articulating) mount — +$30–$50. An arm adds reach and wind load, and is folded flat when not in use.
• Mount a soundbar as well — +$50–$80. An outdoor-rated bar gets its own bracket in the same framing.
• Take down an existing TV first — +$40–$80. Taking down an existing outdoor set is separate.

Why it is done this way

On an inland patio, direct sun and summer heat matter most. An outdoor TV is either an outdoor-rated model, ideally one its maker rates for the amount of sun the wall gets, or an indoor set kept fully under cover and out of direct sun. Many TV makers exclude outdoor use of an indoor set from the warranty.

Stucco is only a finish. The mount goes into the framing behind it, never into stucco alone, and every fastener is sealed where it enters the wall.

Outdoor mounts use hardware rated for outdoor use. Cables are protected, and the outlet must have a weather-resistant cover and GFCI protection under the electrical code; adding one is permitted electrical work for an electrician.

The stucco line in the typical range covers the slower drilling and the sealing, and the mount supplied is its own line.

What would change the price

• The wall behind the stucco is block instead of wood, which calls for masonry anchors.
• A west-facing wall with no shade adds a different position or a canopy.
• A larger TV needs a stronger mount and a wider plate.
• An outdoor outlet that does not exist yet is an electrician's job.
• Wind exposure near the hillside edge may call for a fixed mount in place of an arm.
