Excessive moisture creates an ideal environment for mold and mildew, which can create a range of problems for your home. They can cause indoor air pollution, sagging drywall, and even worsen allergies. If left unchecked, they can also cause structural damage to the home.

Water stains on ceiling and walls are another indicator of leaks. These occur when drywall is saturated with moisture that weakens its fibers, causing discoloration. You might also find peeling paint as a result of water destroying its adhesive properties and pulling it away from the wall.
Faux Muntins & Mullions
In the past muntins (or glazing bars, as they are called in the UK), separated and held the panes of traditional multi-paned windows. After WWII larger expanses of glass that were tempered became available. Today, they're mainly utilized as a decorative element in some older homes.
Rain or wind can cause damage to the support of a single piece or small group of them, creating a crack in the window. The good news is that you can repair the majority of these decaying or brittle components.

Remove any loose or rotting pieces and cut the intersections of the painted vertical and horizontal window muntins with an exacta knife.

Apply a thick coat of white paint to the areas you lightly painted in the initial pass. Allow the paint to fully dry before taking off the masking tape and applying the second coat.
If the problem is more severe such as an hourglass-shaped fracture in the middle of the window, it's recommended to replace the sash. In these cases it's crucial to find an alternative window that is in line with both the style and size of the current one.

Broken Sashes & Frames
A damaged window sash must be a sign that you need to call for help. A broken sash, if ignored, could lead to water leaks, wood rot, and other serious issues to the frame and sill. If you have a broken window sash, replace it as soon as you can to ensure that your window is sealed and functioning.
The problem is often caused by damaged or improperly installed cords. Fortunately, replacing them is fairly easy and is possible in most double-hung windows. First, you'll need to take off the tabs of metal that hold the sash. To do this, you need to push up on one side (it doesn't matter which) of the sash and then pull it towards the opposite side to remove it from the window frame. To reach the sash cords, you'll need to remove the parting strips that separate the sash.

It's important that you examine the metal tabs of the old sash with the new one. If they're different it's difficult to insert the new one in its slot and could affect the way it functions. This can be corrected by placing the tabs in their proper positions on your new window.
In addition to the sashes, you'll have to examine your window frame for any damage or rot. It's a good idea to perform this inspection regularly since wood shrinks and becomes less durable over time, particularly after exposure to the elements. If you spot any visible damage it should be repaired as soon as you can, to avoid the development of a larger issue.
