Impact Windows Quote

I was being quoted $5500 for 1x Sliding door and 2 Single Hung door with Low-E, double glass and tinted.

1x 2009 SLIDING GLASS DOOR (72" x 96") - 2 PANELS, WHITE, XO, 3" SILL, IMPACT, 5/16" - GRAY/XT6129, PVB INTERLAYER, FULL VIEW, SCREEN, SHGC,

UF, VT, DP, PAN #

2 x 2000 - SINGLE HUNG 2 48 W X 51 H - WHITE, IMPACT, 5/16" - GRAY/XT6129, PVB INTERLAYER, FULL VIEW, SCREEN, SHGC, UF, VT, DP, PAN # CUSTOM SIZE

It is an apartment complex and I am on the 3rd floor. So i was wondering if the $5500 is a good quote and $1200 the permit extra so total cost $6700.

Thanks

Thank you
