If you want to go new construction on existing stucco, that is a complicated install and not for the faint of heart of drive by DIY'er.

As long as you are comfortable with that and the fabrication of flashing details (sill pan flashing, drip cap/z-bar, etc.) than you should be fine and it is the more comprehensive installation.

You want to post up some pictures and the first thing you have to do is select your window.

You need to find an actual contractor/builder to do it not just a window installer. Some times the best way to install a window that has stucco is to put trim in place were the old stucco was removed and doing only the smallest amount of stucco patch. Find a window dealer and say you want new construction windows, have them connect you with a contractor that they do business with regularly.

Thanks for the suggestions. I am weighing the opinions but am leaning towards repairing/replacing the stills and stools that are no good and going with replacement windows for now!

But I still gathering info on it! But I saw some Youtube videos and they had the stucco ripped about 5 inches around the window opening and after it was installed; you still have to patch the stucco. That not the way I wanted to do it! Better to just replace or repair the damage window framing and do the replacement window. I can do that myself too! I may schedule it for next Spring/Summer as my next major project!

Plus, I can do shopping during the winter and hunt for the best prices too! Not sure about my bay windows however! I have to check how to do the replacement windows for that but I sure it pretty much the same as the regular windows.

There are ways to more surgically cut back the stucco and not require a patch.

The method that is shown on Youtube is a bit like taking a machete to a hangnail if you as me.

Found out to my shock that I have a frame (brick molding) around my windows already and so I can use new construction windows by removing the brick molding and inserting the nailing fin inside the molding area and install back the brick molding. LOL!

Very nice indeed!

Yes! Don't have to remove any stucco! Yes!!!!!!!!!!!!!!!!!

Any comment would be appreciated.

Well, you saved yourself some time there.

Remove the brickmouldings, remove the flanged unit, prep and clean the openings, install a sill pan or otherwise create a bevel in the rough opening, flash the sill, back caulk the nailing flange, set the unit, shim/square/level/plumb, flash the jambs and head, install drip cap at window head between stucco and trim, install new PVC brickmould, surgically caulk between stucco and brickmould....

Have ice tea and enjoy the fruits of your labors.

Post pictures and add me to your Christmas Card list.

FYI...I spelled Brickmold as Brickmould because I was feeling British this AM!!

The more research I do on this; the more confident I get that it is a pretty easy project. I may need an assistant on some bigger size windows but for the 4 X 6 feet size it a piece of cake to do!

Well, here I am at the end of July and no windows order yet! The big hang up is the bow window! It cost $2,000 more to have Marvin customized the window and the installer is still unsure if that will work! The current bow window is all wood and the Marvin Ultimate is wood with aluminum clad; so their is a difference in manufacturing process and possibly fit!

There seems to be difficulty in fitting the existing opening without modifications even with the more pricey customized $2,000 more additional cost. Total price for this window is: $5,500+!

Can someone offer some advice to me about how to go about ordering this window?

Over all size is: 98" X 54"

Four windows: 54" X 22"

Bays are expensive. A Marvin Ultimate is going to be even more expensive at that. Kind of the worst of both to be honest.
