Cracked glass
Glass that has cracked can make your home look less attractive and allow drafts to get in. It doesn't matter if the cracks are caused by an impact, like a baseball or soccer or a stress like a sudden temperature change, but it is essential to have them fixed as quickly as you can in order to prevent further damage and keep your windows functioning effectively.
If your window is damaged but not broken, an easy solution is to apply clear tape to cover it. This is a quick, low-cost solution to protect your window from dust, water, bugs and other debris. It also shields your windows from the elements.

Impact cracks are the most common window breakage. They typically occur when a solid object strikes your window with enough force that it breaks. The cracks are usually followed by a starburst pattern of lines and broken pieces that can be risky if they break loose. If you have double pane windows, this crack could weaken the gas layer between the panes, which can affect the efficiency of your windows.
Stress cracks are another kind of crack that develops due to extreme temperature changes and other environmental factors. The cracks start around the edge of your window, and can progress to complete breaks.
A more serious but feasible crack is a pressure crack. This is a curvy, curve that extends across the window on one or more sides. It can be caused by high or low pressure which can cause the glass to expand or contract.

Leaking Windows
If you notice a damp area under your window, or the wood around it appears soft or rotting it could be the time to fix your windows.

Unchecked, they may also cause structural damage to your house.
If the water is coming in from outside or visible through the frame it's best to seek out a professional to help you repair the issue right away. Do not ignore windows that are leaking. They are a leading cause of structural damage and mold.
In many cases, a thin layer of caulking is all you need to stop leaks. You'll need to carefully clean the area first though, and get rid of any old caulking prior to applying the new layer.
It is also important to examine the weep holes on the frame to ensure they're not blocked with debris. These holes are designed to remove rainwater but can become clogged over time with insect corpses or other debris.
Examine the seal between the double-paned window and the frame. This creates a gas barrier between the panes, which makes windows more energy efficient. As time passes the seal will be worn out and allow water into your home.
Another indication of leaks is the presence of water-based stains on the ceiling and walls. These are caused when the drywall is saturated by moisture which weakens the fibers and leads to discoloration. There is also the possibility of peeling paint caused by the effects of water weakening its adhesive properties and pulling away from the wall.
Faux Muntins Mullions
In the past muntins (or glazing bars as they are known in the UK) were a way to separate and held the panes of classic multi-paned windows. After WWII, larger expanses tempered glass were available. They're mainly used as a decorative feature in a few older homes.

Often it is the case that a small or even a single group of these wooden supports may get damaged by rain or wind leaving cracks in the window. The good part is that you can repair most of these rotting or brittle elements.
First, clean the affected areas using a rag and an ammonia-based cleaner that won't leave any residue. Take off any rotting or loose pieces and trim the intersections of the painted vertical and horizontal window muntins with an exacta knife. After trimming the intersections using painter's masking tape, you can use the tape to tape off the lower part of the window frame. Then, you can apply a thick coat of white paint, paying particular attention to the areas that were lightly coated in the first pass. Allow the paint to completely dry prior to taking off the masking tape, and applying the second coat.
If the problem is more severe, such as an hourglass-shaped crack in middle of the window, it's recommended to replace the sash. In these situations it is essential to locate a replacement window that matches both the style and size of the existing one.
Installing a grid window is a more affordable option. These windows have a full pane of glass that is topped with muntins that are attached to the surface creating a divided look. These windows are not as energy-efficient as traditional ones.
Installing milton keynes window repair -cap will stop water from entering the window frame. Most home centers sell these drip caps in aluminum for around $20. They are much easier to install than replacement window sashes, and will provide the same functions as a genuine mullion, or a muntin.
Broken Sashes Frames
A damaged window sash must be a sign that you must contact a professional. If it's not checked the broken sash may cause water leaks, wood rot and more serious issues with the frame and sill. If you've broken a sill, you must replace it as soon as possible to ensure that your window is sealed and functioning.
Often, the problem is caused by worn out or improperly hung the sash cords. Fortunately, replacing them is relatively simple and can be done in most double-hung windows. To start, you'll need to take off the tabs of metal that hold the sash in place. To do this push up on one side (it isn't important which) of the sash, and then pull it towards the opposite side to take it from the window frame. To access the cords of the sash, you'll need to remove with care the strip that separates the sash.
Once you've removed the sash, you must make sure you compare its metal tabs to the ones on the new sash. If they're not the same, it may be difficult to place the new sash in its proper place and could impact how the sash functions. Luckily, this is easily rectified by placing the tabs in their correct locations on your new window.
In addition to the sashes, you'll also have to examine the frame of your windows for problems or rot. It's a good idea to perform this inspection regularly since the wood shrinks and gets worn down as time passes, particularly with exposure to the elements. You should fix any visible damage as quickly as you can, to avoid a bigger issue.
If your window frames are deteriorating, you can treat them using a homemade preserver made of half mineral spirits and boiling in linseed. After the treatment has dried, you can refinish your frames with high-quality latex paint. A fresh coat of paint will aid in protecting your window from the elements as well.
