" the windows don't sit behind the stool resulting in a gap that was covered with foam and a piece of wood. "

As mentioned previously the windows are not installed properly if that is the case.

I have talked with Marvin plus researching this more and I cannot get a definite answer if the windows are not measured properly or the Elevate line doesn't fit to our house R/O. That's why I am trying to find if someone has such window installed in a similar old house.

Here is is what I have found through Marvin and other window installers:

1. The house R/O is flat and there is a lip between the inside stool and the outside.

2. The Marvin Elevate windows have a sloped sill on the outside for rain water to float down.

3. The end part of the sloped sill sits on the brick outside resulting to the inside wooden rail of the window to be higher from the stool.

4. The installers who did the work plus another one that saw this are saying that this is normal due to the above. Maybe both don't know how to work in old houses, I am not sure.

5. They are further saying that I will need a different window model, like Marvin Ultimate or Andersen 400 Woodwright, they will definitely sit behind the stool. Especially the latter can be ordered with different degrees/angle of the sloped sill.

6. Marvin does not confirm if the windows are not measured properly, they say the installation is sloppy and that the R/O should have been fixed so this would be avoided, maybe by adding some wood to close the lip or build a slope similar to the window, anything that would make the window sit behind the stool.

I also talked with a general contractor (friend of a friend) about this situation, he went over the below option, which he has seen other window installers doing with old houses, and advised me to run it through window installers. He does not live where I live so he cannot refer me to someone:

1. These houses have wooden exterior trims.

2. If they are removed the interior casing can be accessed.

3. The new windows could be measured to include the length of the casing, which could 1-2'' more.

4. The windows are then installed from the outside sitting on the casing, and of course proper insulation needs to be used, foam, caulking, insulation tape etc.

5. Everything is cased with aluminum as usual.

6. The end result is that the window jamb (the part that rails slide up/down for the window to open/close) sit behind the internal casing including the stool, and pretty much replicate the original windows as close as possible.

Long story short I am not sure if I need a different window model, if the other installation process is a better fit for my house (thermal and noise insulation, aesthetics) or maybe both. That's why I am trying to find if someone has gone through the same and maybe have found some good solution. Thanks for all the help.

Marvin will not throw someone under the bus by directly saying incorrect install in the cases like this. But they said exactly that by reading between the lines. The window is not installed properly, period. The RO needed to be fixed and your contractor is showing his inexperience. The time to correct this was before now. Now you will never get it current. The window cannot sit behind the stool at this point because of incorrect RO.

You were asked by one of the pro's on your previous thread how the exterior was trimmed and for exterior pictures. You never added them or answered those questions.

I missed that part, but provided a pic and my feedback. There is no way I can keep these windows, they need to be replaced. My trust level to any window installer company is very low right now, and it's difficult to find what is the correct path forward. I think I need to start contacting local general contractors as well.

Wound't want to condemn the industry as a whole because someone may have screwed up a measurement here. Pictures are tough to tell from, but I don't know of many, if any, wood out applicaitons that should sit above the stool if measured correctly and the sill is less than 1" out of level.
