Broken Panes
A damaged window can cause many issues, since it could block light, air and even pests. While you could certainly hire a professional to replace the broken pane but you can also do the repair yourself at only a fraction of the cost.
You will need to remove the old window. To protect yourself from lead and glass dust shards, put on safety glasses as well as gloves and a mask.

If the old putty is particularly stubborn, try using a heating gun to soften it prior to scraping it away with a knife. Make sure you wear safety goggles when working with a heating gun, and be cautious to avoid getting any hot wood shards or glass shards in your eyes.
The next step is to prepare the frame for the new pane. To take into account wood expansion and contraction to measure the opening, subtract one-sixteenth of an inch in both directions. Then, have the local hardware store cut you a piece double-strength glass that fits the opening precisely. Dry-fit the glass to ensure it fits snugly before putting it in.
After you have put in the new glass, apply a small amount of latex caulk around the outside of the opening to create an airtight seal. Install the glazing points next to secure the new glass. For standard sizes of window glass you'll only need to install two points per edge.
Once the new compound has dried, you can paint it to match the rest. If you are concerned about cracks that could occur, you can use a heavy-duty masking tape to stop cracks on the surface from becoming worse.
Frames that are damaged
The first thing to do is look over the frame. If there are cracks, rust, or corrosion or the frame has broken into two separate pieces you will need to take it to a professional repair. Metal frames cannot be glued and any attempt to solder them or weld will result in permanent damage.
If the frame has not been severely damaged It can be cleaned with a small brush, some conservation detergent and water. This will get rid of any dirt, grease, or dust that has accumulated through the years. Cleaning old frames with intricate carvings or gesso could reveal the original finish underneath the dust.

Carefully pry the frame apart at the corners, where you can see the nails or brads. Remove the joints and open them up. any glue that is old. Apply new glue.
Loose Compound
The glazing compound that is used to hold glass window panes in their wooden frames is a vital part of any historic building's energy efficiency. It seals wood, binds glass to frame and sheds water to avoid damage from water over time. This compound can be damaged or cracked, which could allow air to enter the frame, reducing insulation values and increasing utility bills. Maintaining a schedule for repairs on double-glazed windows can help keep them running smoothly and efficiently.
The weatherstripping could be worn or loose if you see drafts around your window frames. Replacing the seal can reduce energy bills and improves comfort. If you hear loud sounds outside, such as machinery or traffic, this could mean that the glass tape is worn out.
Remove old tape from the edge of the frame and clean the area thoroughly. Apply a new piece of tape to the edge of the frame and press firmly. You can purchase this at any hardware store and it's an inexpensive way to improve the performance of your double-glazed windows.
Standard super glues are great for wood, metal, and other common materials. However they're not the best choice for glass surfaces. Look for a glass-based adhesive, such as Loctite Extreme Glue Gel. This type of glue has been made to resist sunlight and moisture, which makes it the best choice for repairing double-glazed windows.

Foggy Panes

Foggy windows can lead to many issues, from condensation to calcium deposits to black staining and fungus. It's not just ugly but also leads to lower energy efficiency and increased heating or cooling costs. Fortunately, it is possible to resolve the issue. Foggy windows are often caused by the simple accumulation of moisture and the first step is to eliminate as much moisture as you can. This can be accomplished by applying a defogging spray or using shaving cream. If these solutions do not help then it's time to call an expert.
The reason double pane windows work is due to the space between them. The space is typically filled with argon or krypton which are non-toxic gases that are more dense than air and can reduce heat transfer even more. If the gas has leaking out the windows, they aren't being adequately insulated. Replacing your windows with new IGUs will not only eliminate the fogging issue, but will also boost your home's energy efficiency too.
Many homeowners are under the impression that they have to replace their entire window when it gets foggy, but this isn't always the situation. In fact, some glass shops will provide replacement of just the IGU, or insulating glass unit (IGU) without replacing the entire frame or sash. This is a more affordable option and is just as effective in fixing your windows.
While there are a few DIY solutions to avoid window condensation, like shaving gel or defogging lotion it is best to call an expert to ensure the job is done safely and correctly.
