I specialize in wall mounting TVs, as well as anything else going up on walls, such as: Shelves, pictures, cabinets etc....
Basic drywall TV mounting is only $89. (Labor).
Optionally as needed:
Add $35 for masonry installation.
Add $42 for tilting mounting bracket.
Add $62 for full motion mounting bracket. (Less for small TV.)
Ask about same or next day service. (Often available without additional cost.)
2nd and subsequent TVs mounted on same appointment is $20 off on each.
