Wondering what others have paid for a HVHZ rated sliding glass door and installation in SE FL. It's a 71.5x80 sliding door and a screen.

First quote was $5700 for the door, framing, labor, permit and disposal thru Lowes.

I've got 2 more companies scheduled to come within the next week to give quotes. Just curious what others might have paid for a similar door in this area.
