Safely Remove Large Bracket Mirror which maybe hooked to wall

I have a single, oversized wall mirror—well over 4 ft by 4 ft—that was secured with metal brackets rather than adhesive. I need it taken down intact, without damaging either the glass or the wall surface behind it. Once it’s off the wall, you can either leave it neatly in the room for me to handle or haul it away if you offer disposal; just let me know which option you provide.

Please bring the right tools for bracket removal, glass handling, and basic wall touch-up so there are no exposed fastener holes left behind. Experience with large-format glass is important; the mirror is bulky and will likely require two people to manage safely.

The job is straightforward: arrive, detach the brackets, lift the mirror off, protect surrounding finishes, and tidy up. I’m flexible on timing this week, and access is easy—ground-floor room, no stairs.

If you’re comfortable with large mirror removal and can guarantee a clean, damage-free finish, I’d like to hear how soon you can schedule the work and roughly how long you expect it to take.
