Project example: a 55-inch TV on an interior partition in a condo, away from the shared wall — what it looks like and what it costs

The scenario

The unit is a third-floor condo with an open living area, a balcony door on one side and the wall shared with the neighbor behind the sofa. The only other long wall is an interior partition that separates the living area from the hallway.

The request is a 55-inch TV that does not carry sound into the neighbor's home. The household had considered the shared wall because it is the largest, but the association's rules limit holes in it, and the neighbor's bedroom is on the other side.

The partition is framed with studs that look like wood on the finder but feel lighter than expected, so the installer checks whether they are metal before choosing the fasteners. The complex has a gated garage and asks contractors to call the office in advance.

What the job involves

1. The installer calls the management office for the contractor rules and books a visitor space for the day.
2. The partition is probed to confirm what the studs are made of; here part of the wall is wood and part is metal.
3. The plate position is chosen over two wood studs, with the metal section avoided.
4. Pilot holes and lag bolts go into the wood studs, and the plate is leveled.
5. The TV goes on the plate and the lock screws are tightened.
6. The cable runs in a short raceway to the outlet beside the console.

Hardware and materials

• Fixed or tilting mount rated above the TV's weight
• Lag bolts for wood studs, with fasteners rated for metal on hand
• Stud finder, probe bit, laser level
• Short raceway kit
• Drop cloth for the carpet

Add-ons often paired with this job

• Full-motion (articulating) mount — +$30–$50. A swing arm on the partition would let the screen face the kitchen counter as well.
• Mount a soundbar as well — +$50–$80. A bar on its own bracket on the same wall.
• Hide the wires inside the wall — +$90–$150. An in-wall kit is possible on the partition only if the association allows work in the wall.

Why it is done this way

The shared wall is the largest in the room and the wrong one for the TV. CC&Rs often limit holes in it, and sound and bass travel into the next home. The interior partition keeps the household's noise in the household.

The probe is what separates a good install from a risky one in a building with mixed framing. A lag bolt that finds metal instead of wood will not hold, so the installer knows what is behind the plate before drilling.

Because it is a plain drywall wall with no extras, the example sits at the bottom of the range for a 55-inch screen.

Condo work is mostly about etiquette. The visit is short, the tools come in by the nearest entrance, the garage gate is opened by a code from the office, and the carpet is covered from the door to the wall. Nothing is drilled before the management office has confirmed the contractor hours, and the hole count is kept to the four the plate needs.

What would change the price

• The partition turns out to be all metal stud and the fasteners change.
• The association asks for a form or a deposit for contractor work.
• The owner adds a soundbar or a swing arm.
• Going up from 55 inches to 65 would stay in the same price band, but 75 would not.
