LOL and ya 2k a window is a major con job. Depending on what windows you have now and what you are going to the prices do vary. I'm still swapping out the ones in the rental house I live in as landlord permits. Single pane wood to double pane vinyl at a cost of $108 each and 30 minutes per window. For these all I have to do is pop the stop around the inner frame, yank out the track/sashes, put new window in, reinstall the stop caulk/paint casing and outside install the angle strip on bottom and done. That is about as simple as it gets though. Even with good grade windows( material cost of $300 and real $300 not some $100 priced as $300 ), casing and wrap, it shouldn't exceed 500-600 per window. If it does, use another company unless you are doing some fucked up request for arch windows using cladding, multiple tones such as tan outside/white inside, and triple pane platinum 8 headed spark plug type of shit. Then a person deserves to pay 2k a window.
Never understood it, windows is one of the easiest things in construction yet highest markup/price there is. Even worse than roofing.
Even a custom large window ( 32inches wide 70ish inches tall ) runs under $200 ordering directly yourself. Add in funky shit like all the upgrades/2 tone/cladding and/or impact resistance and it still is under $400 a window. For most people though insulated vinyl frame, white, double hung with half or full screen, 2 locks with 2 catches is plenty of a window and even with grid in glass is less than $220 a window and older homes where the windows are 36x37 or 36x54.5 and less they run $100-140 for normal store brands. Installation varies but in some cases it is less than a hour labor like mine per window, in other cases with wrap and having to recase it is still under 2 hours a window.
I see those fuckers all over town and have for ages though. "Window" people. They spend more time looking busy doing nothing to justify the fucked up price than actually putting it in.
