Broken Glass
Cracked windows aren't just unsightly but can also allow valuable heat and sunshine to escape your home. Fortunately, it's often possible to repair a broken window without the need for a complete replacement.
Start by putting on protective gloves and safety goggles. You can also apply duct tape or painter's tape to make an "X" on the glass you want to remove. This will prevent any broken pieces from falling as you work, which could keep you from serious injuries.
Cover a small scratch on your window glass with tape to keep bugs, water, and wind out. If the crack is only superficial, a single strip of tape is enough. However should the weather be expected to worsen before you can replace the window, you may want to use a heavy-duty plastic cover like an tarp or trash bag.
For cracks that aren't as deep try using a tough adhesive specifically designed for windows, such as Loctite Super Glue Glass. This high-tech adhesive is formulated to bond to glass and it dries crystal clear to give an ideal finish. Apply it to the crack and let it dry completely before applying a new layer.
Glass windows can also develop stress cracks. They are usually caused by large changes in temperature and they can quickly spread across the entire glass window if not fixed. To stop stress cracks from occurring, score an arc of a tiny size with glass cutters near the crack. This prevents the crack from spreading and can slow it down by a few days.
If you're replacing a broken window take measurements of the frame to determine the size of the new pane. It should be slightly larger than the opening to allow for expansion and contracting, as well as to account for any imperfections that may occur on the frame or the glass. After cutting your new glass, apply glaziers' compound around the edges of the frame and glass. Once the compound is dry paint it over to match the frame of the window.
Double Glazed Windows Condensation Inside
The appearance of condensation on the inside of double-glazed windows typically indicates that the seal has been damaged at some point along the window unit. This is an important issue because it indicates that heat from your home is being lost through the window and could be costly for you and your energy bills.
Double glazing has been designed to block heat transfer between the two panes of glass by sandwiching a layer air or a vacuum between them. This creates a secure seal that stops warm air from venting. However, if the glass is colder or colder than the frame, then condensation can form on it, which can damage the window. If you are unable to resolve condensation on a double-glazed window by opening windows by using extractors, dehumidifiers or trickle venting, you may require a professional.
It's less likely to see condensation appear on the outside of double-glazed windows but it can happen if the seal between the glass and window frame has begun to weaken. It is more prevalent in winter, when temperature is lower. This makes it easier for condensation to form. The main cause of this is a defect in the spacer that is placed between the window and the frame. This spacer contains desiccant, which is extremely absorbent and will absorb any excess moisture.
The problem with this is that once the desiccant becomes saturated it will begin to break down and then moisture can start to leak through the gap between the glass units. This could cause condensation and water to build in the gap which is difficult to clean out.
The majority of reputable window manufacturers offer a warranty and replace the unit and glass of a window if it's damaged due to condensation. Make sure to report any issues as soon as possible to the window manufacturer so that the condensation can be repaired as fast as possible to avoid further damage.

Clean it off and then apply an oil coat of linseed to the rabbet. This will allow the new putty to stick in place.
After the frame has been cleaned and the rabbet has been prepared It's now time to make the replacement pane. Find the height and width of the opening in both directions, then order the double-strength piece of glass that is 1/8 inch shorter in both directions. You'll need to purchase glass points, which is a metal triangle that keeps the glass in the right place.
With the window sash off the way, gently pry it away from the wood molding using a flat pry bar. You may need scrape off old glazing putty with a knife or chisel. Utilize the heat gun to warm any putty that isn't able to be removed easily. This will make it much easier to remove it.
