What are your thoughts regarding the price of the window and the finishing work? Also, our current bays have seats and I don't care for them and the current "curve"
Of the window is 45 Degrees and I would like to change that to between 30 and 35 degrees. Is it possible to make these changes with reconstructing the window opening?
Base Scope of Work: Skylights
Remove 2 existing skylights at front of dwelling. Remove interior finishes to height of new skylight. Install new deck mounted, aluminum/vinyl fixed skylight by Velux. Furnish and install new roofing around skylight as required for a watertight installation. Repair interior finishes as required. skylights do not fit under any standard sizes and unfortunately will need to be ordered to the size of the opening. The most cost efficient replacement method here would be to cut down the drywall and install a flat/deck mounted skylight instead of replacing the curb.

Wendy, the price doesn't sound out of line for the work. I'm not a finish carpenter, so I can't answer these specific questions about changing the curve of the bay.
I would get a few more bids here as you might see some significant differences in price because this is such a unique project. Bay windows and their installation can be complicated, but also the bid prices are often all over the board.
It usually pays to get a number of different bids from local contractors and window installers.

Small Bay Window Question
Hello Dane, when we have sales people to give us a price it seems they have two ways of telling me how many windows we have.
We have casement, sliders and picture windows. My problem comes around the casement windows. If we have a window that has 2 crank out panels, is that counted as 1 window, or 2?
We have a small bay window in the dining room with a "seat". It is a 1/3 - 1/3 - 1/3 with the two ends crank out and the center glass. Is that counted as 1 window, or 3? The window in the kitchen is the same, 1/3-1/3-1/3 just not a bay window. Is this 3 or 1 window?
Thanks.

[Site Editor's Answer]
Rich, most times the dealers/sales people are pricing out windows by the lineal foot, with a base rate for each type of window. So a casement would have a certain base rate, a double casement would have another base rate for the series you are buying. Then they would alter the price based on the size or lineal feet of the window.
Bay windows are often priced out in a similar way, a 3 panel bay window would cost X, a 4 panel bay window would cost X. The bay window becomes more difficult though because your opening might require a different configuration where they would have to custom make the bay and mull the windows together onsite. That’s one reason why getting a bunch of bids to try and find a company that can simply buy the “bay box” and then insert their windows into the openings. Then you’d be paying for 3 windows and the cost of the premanufactured box.
I hope this all makes sense. When you have these tricky configurations, it’s tough to talk about the per window cost. Best to compare the different bids and see if the salespeople can breakdown the quote for the larger configurations to serves as a basis of comparison.
All The Best.

Thanks for the explanation, although to be frank, it doesn't help much. I read on your site people paying anywhere from $400 - $700 per casement window, while mine are being priced by at least 9 local installers and 5 different manufacturers at $1400 +/ per window (not including $3500 - $5000 for the small bay and 1/3 - 1/3 - 1/3 windows.. Of course when I say that's too high, or someone else can do it for less I get one of two responses:
1) Well, our product and installers are much better quality, their warranty isn't as good, or
2) I found a dealer volume discount from our supplier, or we're running a special, or if we can use you as a reference, yada, yada, yada... and then they lower the price.
And of course they pretty much all say they can get the job done in 2-3 days using 2 people. This is for full face, 13 windows, some sliders on a porch, the two bays, and a mixture of regular and 2 large 1/4 - 1/2 - 1/4 windows. My best estimate is they must be paying $85-110 per hour for labor, which I find difficult to swallow, since only two claim the workers are employees rather than long-term independent contractors.
I appreciate your information, but it looks like I'm no closer to figuring out what's reasonable and what's just gouging. I was hoping to approach negotiating with them from a sense of knowledge.

Sorry to hear about the pricing Rich. I hear about all sorts of stories -- some consumers quote prices that seem unusually low and others get quoted prices that seem unusually high. If you have a number of bids and they are all in the same basic range, then that's probably the "fair" market price for the particulars of your job.
Larger window configurations and bay windows can be incredibly expensive depending on the specifics involved in the job. However, a standard vinyl casement window with installation should not run $1400, unless you are buying a wood window. Now, a double casement, with two handles--I could see that running somewhere in the $1400 department, but not for a standard vinyl casement.
I would say this--continue to get free bids from local companies until you have a firm handle on the project/price. If they continue to be that expensive, then that's probably the going price for your project. The one good thing about the bid project is that sooner or later you will find a good/great deal...or at least one you can accept as the best you're going to get.

Bay Window Cost Calculator
We live in the Pittsburgh, PA area and are getting quotes from a few local companies on replacing a 27 year old Kensington bay window. Approx 92 x 44". The old bay has casement flankers with colonial muntins and full screens.
We used your Replacement Window Cost Calculator which gave us prices of $1630 (vinyl frame), and $1770 (wood frame). The three estimates we received so far range from $8000 (Andersen), to $4600 (Polaris), to $4200 (Alside) to replace the bay. We did get a price of $1855, but that was to install a picture window with 2 casement flankers with colonial muntins in the flankers only. So far, haven't found anyone near the Calculator prices.
Bob - Homeowner - from 2016
[Site Editor's Answer]
Bob, the calculator takes perhaps 6 pieces of generic information and gives a ballpark price. However, a particular project, especially a bay window, has more like 20 different factors that influence the price. For instance, the size of a window or a bay will have a huge affect on the individual cost, but it's too tedious to put into a calculator and just doesn't make sense for the average user.
Bay windows often require lots of work to remove the existing window, repair the wood and frame to get it ready for the new bay window. So I do apologize that the calculator was off in your case.
The estimates are going to give you a MUCH better idea of what the fair market value is. Andersen is always going to be at the high end and I would throw this one out unless you have to have wood, but it sounds like it's way out of your price range.
Polaris makes a very nice window and this is probably the mid range of the cost spectrum. I'm not a big fan of Alside so I would throw that one out if I were you.
I would suggest a couple more bids from local companies that sell Simonton, Vinylmax, or Wincore -- these are three mid range window manufacturers who sell a quality product at a fair price point.
