Free windows doesn't seem right. If the color isn't that bad, maybe half? Or, maybe some other upgrades that are basically free for the builder's team to do but would cost you. For example - more electric work, more trim work, wider driveway. That is what I would do anyway.

Sorry, but from your other thread, you are ending up with what you wanted anyway with site painted on the interior windows. That doesn't deserve a credit for anything. You are getting what you wanted.

No the interior is ok but the exterior is now wrong.

If you want advice, you need to tell us what you wanted and what you got. It would also help to know what kind of windows are involved and what the house looks like.

Wanted white exterior pella 450 windows. Exterior came in black. House is a craftmanstyle w/ Hardie aged pewter(gray) white trim and gray roof

Oh -- I love the look of black exterior windows.

Without seeing the house all I can say is that I would never think of using white windows or trim for a Craftsman house. It would be contrary to the essence of the American Craftsman Movement. Of course, people will call almost anything a Craftsman house these days. But unless its a Colonial or Colonial Revival house I would not use white on the exterior.

Even my house, an 1891 Colonial Revival, originally had black windows with white trim and I have recently restored the colors and the window look much larger.

I recommend getting rid of the white trim and finding somone to help you chose more appropriate Craftsman colors.

Call it serendipity and thank your stars they didn't come in white on the exterior. Black on the exterior and wood on the interior is a HUGE upgrade over what you wanted. It is much more appropriate and you will end up with a better appearance.

Pella is one of the few window manufacturers that still uses roll-formed aluminum cladding. That means the aluminum cladding is not thick and mitered but thin and lapped. IMO such joints are unsightly where you can stand near them like on a porch. I would guess that black would obscure this "feature" better than white.

Show us a photo of the house. Since it sounds like you are going to keep the windows we might be able to suggest a way to integrate the back windows into a nice Craftsman color scheme.

As for the credit, if the mistake turns out to be beneficial you would not ask for much and thereby maintain a good relationship with the builder. Being far is a tremendous good will builder. As the architect of a large addition I made a mistake in the window order and everyone involved, including the owner, helped to reduce the cost of correcting it. I was able to pay them back for that consideration many times over.

Its a very nice design. But it stops short of adopting the principles of the Craftsman Movement. These houses were designed to have a close relationship with nature and used materials and colors from nature. You have the stone and shingles right but the colors are from our never-ending fascination with Colonial America. Off white or cream is great but never bright white. Gray is too colorless and the contrast between gray and white is too severe. Craftsman houses should not be cold or turn their backs to nature.

It would take too long to find a lot of examples so I'll just show you one on the National Register of Historic Places that I have always liked, the Louis T Gilliland House in Portland OR. The design was from Gustav Stickley's magazine The Craftsman. The colors are compatible with the natural materials and landscaping.

By the way, if you are going to have full height screens, no one is ever likely to know what color your windows are.

The vent in the front facing gable is not appropriate. Omit it and foam the rafters if ridge and eave vents are not possible.

Without seeing the house all I can say is that I would never think of using white windows or trim for a Craftsman house. It would be contrary to the essence of the American Craftsman Movement.

Sounds like you got a blessing in disguise.

what are the solar heat gain coefficients & ufactors? do they differ between windows chosen & windows installed.

granted y'all are worried about looks, but performance of the window

should be a motivating factor also.

don't know the other threads, just replying to this one.

best of luck.

e_r_la, they are Pella 450's. Black is an upgraded cost from any manufacturer, generally a fairly sizable upgrade at that.
