New flush fin windows, recessed stucco arch above old frame
 
2 Attachment(s)
Hey everyone, first time poster here. Been working over the past year and a half to remodel my house, got most of the inside done and now I'm on to the windows.

I'm located in Phoenix AZ, have a stucco house built in 1984. Original windows are aluminum frame, and after doing some researching online I decided to go with vinyl flush-fin replacement windows to avoid cutting and patching the stucco. I have a total of 5 windows to do, but only ordered 1 to start with, figuring if that one goes bad I'm only out $400 rather than $2000 :laughing:

The one window that I did order is has a recessed arch above the window. I'm trying to figure out what the best way is to deal with this. I'm going to need something to fill in the gap created by the top fin on the new window and the recessed area. Do I just fill this with stucco? How do I go about sealing it? Of course I had to pick the difficult one to do first.


Pics attached. TIA!

Furr out that added depth with a piece of synthetic lumber or foam prior to apply the frame jump window and sealant.

I would still recommend a kerf cut into the stucco and a drip cap above the new window.

Sounds good, will report back once it's done. Thanks! Should be another week or two before the window shows up.

unless you get the vertical leg of the drip cap up under the paper what good is it?

to effectively install a drip cap under stucco you need to make a score cut a few inches above the opening,taking care not to cut the mesh,then carefully clean the old stucco off the wire

this makes it much easier to properly flash the opening and get a good key for a stucco patch

I agree, however, the drip cap in this capacity is not intended to handle any of the moisture behind the stucco like a real drip edge would.

These type of stucco flange windows rely on a single caulk joint at the heat of the window to keep out any water that flows down the front of the stucco from getting behind the window. He is leaving the entire frame of the old unit intact. I was merely recommended another layer of water management to shed the water that is running down the front face of the stucco.

For the record, I prefer your method but based on the customers feedback, I am not sure he is going to go that full blown route. We have done jobs like these and just cut the stucco back and applied 5/4 azek in lieu of the patch once the stucco was removed in the exact footprint of the azek.
