The window must be at least 20 yrs old..

For some reason the left sash cord is stuck and I cannot lower the window. It is stuck almost in the hihjest position. When I raise the widon to its limit slack is formed in the cord. It is definitly bound up for some reason. I'm not sure if this window uses springs or weights.

How can I repair this situation? I know I can cut the sash cord and at least have the window lowered during the winter months.

Are you sure that these are Anderson windows? Most Andersons manufactured in the recent past use a clock spring mechanism in the window head to counterbalance the sashes.

If your window does have sash cords running into the jambs, it probably uses metal counterweights in the wall. Carefully remove the vertical facing trim (the trim board between the frame and the wall). Inside the wall you will find a vertical space containing a metal weight tied to the end of the sash cord. It is likely that the weight has hung-up on something. Clear the obstruction and check the window operation. If the sash operates smoothly you have fixed the problem. Replace the trim, putty stop the nail holes, and paint.

While the trim is off you might want to install a new sash cord. This entails a lot more work including removal of the sash itself. There are books at your local builders store explaining this operation in more detail and with pictures.

Good Luck

I'm sure they are Anderson.

I put them in years ago.

A ********** person gave me suggestions.

For the winter I cut the core so I coul close the window.. and you are correct there is a counterbalance system in the top of the window but was told it isn't that expensive to replace.

Spring project..

The Narrowline window has a sash Balance system in the head jamb. If it worked fine until now the spring must be bad. It isnt too difficult to replace. Measure the visable glass size on one sash. (That will determine the window size) Call a local Andersen dealer with that information. They will be able to determine the size from that glass size. Just be sure you tell them that its a Narrowline product. They can order the right size balance for you. It comes with instuctions on how to replace. If your not a handy person, a contractor should be able to do that in 10 min. Dont overpay him.....
