Double Glazing Quote

mparter

I'm in the process of getting some quotes for replacement double glazing. I've had 2 companies out so far with another coming tomorrow night. Company A hasn't sent me a quote yet, Company B quoted on the spot. Going by what I'm looking to get done below, is a quote of £7551 expensive?

1 x French Door (1700 x 2100)
1 x Living Room Window (2100 x 1200)
1 x Kitchen Window (1100 x 1000)
1 x Back Door (Split Panes, 840 x 2050)
1 x Toilet Window (300 x 1000)
1 x Front Door (940 x 2050)
2 x Bedroom Windows (Tilt/Turn, 1100 x 1700)
1 x Bedroom Window (Tilt/Turn, 1100, 1200)
1 x Bathroom Window (600 x 1000)

To fit the living room window requires the removal of a patio door, and some brickwork obviously to then fit the window.
