Faux Muntins & Mullions
In the past, mullions and muntins (or glazing bars in the UK) separated and held glass panes in classic multi-pane windows. After WWII larger expanses of glass with tempered were made available. They're mainly used as decorative elements in a few older homes.
Rain or wind can cause damage to a single support or a small group of them, creating an opening in the window. The good news is that you can repair the majority of these rotting or brittle components.
First, clean the affected areas with a sponge and an ammonia-based cleaning agent that won't leave a residue. Remove any loose or rotting pieces and trim the intersections of the horizontal and vertical window muntins using an exact knife.

They're much simpler to install than a replacement window sash, and they'll provide you with the same functions as an authentic muntin or mullion.

Broken Sashes & Frames
A broken window sash is an obvious sign that it's time to seek some help. A sash that is broken left unchecked can cause water leaks, wood decay and other serious problems to the frame and sill. If you have a damaged sash, you should replace it right away to ensure that the window is properly sealed.
The problem is often caused by damaged or improperly installed cords. Luckily, replacing them is fairly easy and can be accomplished in most double-hung windows. To begin, you'll need to remove the tabs made of metal that secure the sash. To do this, you need to push up on one side (it does not matter which side) of the sash, and then pull it toward the opposite side to remove it from the window frame. To access the cords for the sash, you'll have to carefully remove the strip of separation that separates the sash.
It is crucial to compare the metal tabs of the old sash to the new one. If they're different, it will be hard to place the new one into its slot and affect how the sash operates. Fortunately, this can be easily corrected by simply placing tabs in the correct positions on the new window.
In addition to the sashes, you'll have to examine your window frame for any problems or rot. It's a good idea to do on a regular basis, as wood will shrink and wear down as time passes. You should repair any visible damage as soon as possible to avoid a more serious issue.
