How do I replace the sash of a single hung window?
If it is an older window let say 50 to 100 years old or soThe sashes were not really made to be replacedHowever most can be done with a little or a lot of workSome windows are so labor intensive that it is easier to replace the window and get a new energy efficient window Most of the time the trim will have to be removed to get to the window frameOnce you get to the frame you will see a little access door that is screwed in placeAnd if the sash weight has broken off it could be in the wall on the floor plate and then you have to buy a new one or cut a hole in your wall to get the old weight outBut if it still intact then you can open or close the window until you can grab the weight and untie itand replace the cord if that is what needs to be replacedThe Knots need to be tied the same way so make note of how it is tied onPut it back together, providing you did not break any of the 100 year old trim This job is not easy as the trim will need to be repainted and the trim may have to be sanded and then again old trim paint may have lead in it and can be toxic while sandingAll the above is why it is more easy to just replace the window with a good energy window that you may get a tax deduction forSome windows come with the trim package already attached and you just slip it in and caulk the outside.
