+1. Repairs that would be a waste of money. If the frames are in good shape and you can source a replacement sash, that is probably an option to consider, but I don't think repair of that specific sash is a cost effective option. As MWM inquired, how are the rest of the windows in terms of condition?

You would be best served getting replacement windows. Try staying away from wood windows.

Thanks for the suggestions. Does a replacement sash include glass? It is a twin 24x60 casement window. If i go Marvin Integrity all fiberglass how much roughly will it be including installation. The house was built in 1998 but i don't know how old the windows are. Here is another picture of the sash. Don't know if you can evaluate the condition of the frame based on this picture. I will try to get more pictures. Thanks.

The picture was more to see the current exterior elevation to get an idea how one replacement unit would look overall compared to the balance of the windows in the house. Yes a new sash would include the glass, the existing hardware would normally be reused but the sticking point is you need to know the manufacturer to get a sash and 1990's vintage the manufacturer may not even be in business any longer. As far as cost for the window you mention it will definitely be location specific and determined by the type construction and ease of installation.

In my old home I was able to repair them. It made sense because I wasn't going to be there long.

Call the manufacturer. They might have something like I found.

My experience at the bottom of this thread:

Here are a few pictures both from inside and outside. It is Pella window and I called Pella today and they said they will schedule a service call but it is not free.

jn3344, thank you. I called Pella but was told it is not likely the sash is still under warranty. They asked for a serial number, which I could not locate on the window. So they can not give a quote on the parts either unless a Pella technician identify the model and year of make on site.

Frames appear to be okay from the exterior. Unless you are doing a full house project, I think the idea of flushing out the sash replacement price is not a terrible idea to at least have a baseline.

ok, just got a Pella sales visit and he said they can replace both the sash for $1000. To do a whole window replacement including labor it will be $2000. The same Aluminum clad wood Pella Proline window. Sounds this includes the frame replacement as well. The size of the sash is about 29x60. It is a twin casement window so the whole window size is about 58x65. Does it sounds about the right price?

That price sounds about right for an overpriced wood window. If you plan on staying in the house a while I'd try to source other product options. Just because they are Pella now doesn't mean they have to stay that way. I would venture to guess that this isn't the only window unit show signs of ware. And while it may be the worse there are usually others to follow. You could probably save quite a bit of money and get better performance from the nicer vinyl windows. If you like wood, most professionals would agree that Pella proline isn't one of great quality

Thanks. Actually i like fiberglass more. It is just the whole house is al-clad wood and I am not planning to replace all of them at the same time. If I go the full replacement route i probably use Marvin fiberglass. Again the rest of the house are al-clad so still debating.

How old are the units again? I realize that you do not want to replace all of them, but more often than not, the condition of one is indicative of the condition (or impending condition) of the rest. In this case, it is not like this unit was behind a tree, bush, or subjected to any more weather or moisture than was likely experienced by the other units.

Might be time for a careful inspection of the remaining units and look at the project, unfortunately, in more totality.

This is not the rule, just an observation. Hopefully the other units are just fine at the end of the day.

Thanks. The house was built in 1998 and i suspect the windows are original ( I might be wrong). The Pella guy did check the other windows and said they are fine for another 5-10 years if properly maintained.
