It is possible to replace glazing points with the window in place but it is much easier and quicker to remove the glass and frame. It is a good time to replace the rubber seals.
Broken Glass
Cracked windows aren't just unsightly but can also let valuable heat and sunshine to escape your home. It's possible to fix the glass that is cracked without having to replace the entire window.
Begin by putting on your protective gloves and safety goggles. You can also employ duct tape or a painter's tap to create an "X" on the glass you want to remove. This will prevent any broken glass from falling on your work surface as you work.
Cover a small crack on your window with tape to keep insects, water and wind out. If the crack is superficial, a single strip of tape is enough. However should the weather be likely to get worse before you can replace the window, you may want to use a heavy-duty plastic cover such as a trash bag or tarp.
For cracks that aren't quite as shallow Try using a strong adhesive specifically designed for windows, like Loctite Super Glue Glass. This high-tech adhesive is formulated to bond to glass, and then dries crystal clear for a perfect finish. Apply it to the crack and allow it completely dry before applying a new layer.
Glass windows may also develop stress cracks. They're typically caused by dramatic changes in temperature, and they can quickly spread across the entire glass window if it's not fixed. To prevent stress cracks, score an arc of a tiny size with glass cutters near the crack. This stops the crack from spreading and can reduce the size by a few days.
Measure the frame of the broken window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction, and to compensate for any imperfections in the glass or frame. Once you've cut your new glass to size apply glaziers' compounds around the edges of the frame and the glass. Once the compound is dry, paint over it to match the rest of the window frame.
Double Glazed Windows Condensation Inside

This is a significant issue because it indicates that the heat that is coming from your home is being lost through the window and can be costly to both you and your energy bills.
New double glazing is designed to block heat transfer between the two glass panes by sandwiching a layer air or a vacuum between them. This creates a secure seal that blocks warm air from venting. If the glass is warmer than the frame, condensation can develop on the glass and cause damage to the window. If you notice condensation on your double-glazed window and you cannot resolve it by opening the windows using extractor fans, using dehumidifiers, or by trickle venting, then you may require the help of an expert.
Condensation of the outside of double-glazed windows is uncommon however it can happen if the seal has begun to weaken between the glass and the window frame. This is more prevalent in winter, when the temperatures are lower and it's more easy for condensation to form. The main cause of this is a flaw in the spacer that is placed between the window and the frame. The spacer is often filled with desiccant that is extremely absorbent and will soak up excess moisture.
This could result in moisture seeping through the gap after the desiccant has been saturated. This can lead to condensation and water leaking into the gap, which is difficult to get rid of.
The majority of reputable window manufacturers offer a warranty and replace the unit and glass of a window in the event that it's damaged by condensation. It is crucial to report any problems to your window installer when you notice them, so that condensation can be addressed as quickly as possible to avoid further damage to the window unit as well as the frame surrounding it.

Apply a coat linseed to the rabbet, then wipe it clean. This will aid in helping the putty to stick.
Once the frame is cleaned and the rabbet ready, it's time to plan the replacement of the broken pane. Take measurements of the width and height of the opening in both directions and then purchase an item of double-strength glass that is 1/8 inch smaller in both directions. Also, you'll need to purchase glass points, which are made of metal triangles that keep the glass in place.
After removing the window sash, use a flat pry-bar to carefully pry the sash free of the wood moulding. You may have scrape off old glazing with a knife or chisel. Then make use of the heat gun to warm any putty that won't easily be removed. This will make it easier to remove it.
Once the frame has been free from the molding, carefully press the new glass into the frame. Fill in the gaps using the glazier's tip or a putty knife. When the putty is dry paint it in a manner that matches the frame. Paint the glass and the compound by overlapping the paint slightly.

Use a wire brush to clear the frame opening of any old paint or wood gunk and then sand it down to bare wood to enhance the seal between the frame and sash.
Make use of the edge of the putty knife while inserting the new pane to lay it gently against the frame of wood. Press glazier's tips into the frame every six inches. This will keep the new window securely in position.
