In time, any window might need minor or major repairs. Of course accidents happen, (e.g., neighbor practicing hitting golf balls!) and you might find a replacement window (glass) is necessary. So far this has not happened!😊
Over the years, I have replaced (most) of the original single pane windows with Pella windows. For the most part, I have been happy with the results. One of the main reasons we selected Pella was the "in the window" blinds.
I have the "raise and lower" blinds in several windows, and had to replace the "ropes" in several. We chose this version because we weren't sure if looking through "blinds" would obstruct our view. This proved to be an unwarranted fear because within a few days, we didn't even notice the blinds (as a distraction or obstruction) when looking outside!
The blind is down and tilted closed in this photo for illustration
After the above experience, we had more of the original windows replaced without the raise and lower feature. There is just a knob at the bottom that opens and closes ("tilts") the built in blinds, but does not raise and lower them.
These sometimes break...lots of luck finding a replacement. I had to cash in a CD to get one.
The new Pella windows seemingly have improved some of the problems with the "older raise and lower type" built in blinds. The newer ones have two "operators" to raise, lower, and to tilt the blinds. They operate with a few magnets, that move the blinds. One reported problem is when the operator is moved too fast, it renders the operator temporarily inoperable. Pella provides instructions on how to reengage the magnets.
I am planning on having my early 1990's Pella bow window replaced soon. It takes some real skill and patience to remove the inside pane to "restring" the older type "rope" inside the two panes...without cracking the window! I did several...not a picnic!😀
Another common problem on the older vintage is the window operator arm on the casement windows, i.e., the part the window crank is attached to open and close the window sash. The sash is the part of the window that holds the glass panes together, creating a frame around the glass.
When I say common, I mean it is a common problem on any casement window that I ever worked on, regardless of brand. Over time, depending on usage (e.g., often, never, weightlifter arms, pipe cleaner arms 😕), these parts can wear out.
One final problem that I'll mention is the window hinge shoe and the window pivot plate hinge shoe. These are a few plastic parts that help your casement window open and close smoothly.
