Broken Glass

Windows that are cracked aren't just ugly, but they can also allow valuable heat and sunshine to escape your home. Fortunately, it's possible to fix a broken window without having to go through a full replacement.

Start by putting on protective gloves and safety goggles. Also, you should put a piece of tape in an "X" shape on the glass you plan to remove (duct or painter's tap works well). This will stop any broken pieces from falling as you work, which can keep you from serious injuries.

If you have a small crack in your window glass you can cover it with tape to block the elements like wind, water and insects. If the crack is only superficial and only a single strip tape is enough. However should the weather be expected to worsen before you can replace the window, you may need a more durable plastic cover like a trash bag or tarp.

Make use of a strong adhesive that is designed for windows to fix cracks. Loctite Super Glue Glass is a good choice. This high-tech glue is made to adhere to glass and dries crystal clear for the perfect finish. Apply it to the cracks in the glass, and let it dry completely before applying a second layer.

Stress cracks are a different problem that can happen to your glass window. They're usually caused by significant changes in temperature and they can quickly spread across the entire glass window if it's not repaired. To prevent stress cracks, score an arc of a tiny size with glass cutters near the crack. This will stop the crack from advancing, and can slow it down by a day or two.

Examine 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. After cutting your glass, apply glaziers compound around the edges of the frame and glass. After the compound has dried, paint it to match the frame.

double glazing window repairs on the inside of Double Glazed Windows

The appearance of condensation on the inside of double glazed windows usually indicates that the seal has been damaged at some point along the window unit. This is a serious issue, as it can mean that heat is being lost from your home through the window.

Double glazing is designed to prevent heat transfer between two panes by sandwiching an air or vacuum layer between them. This creates a airtight seal and prevents warm air from leaving the house. But, if the glass is colder or colder than the frame, then condensation can build up on it, which can damage the window. If you are unable to solve condensation issues on a double-glazed window by opening windows by using extractors, dehumidifiers or trickle venting, then you might need a professional.

Condensation on the exterior of double-glazed windows is not common However, it could happen when the seal has started to deteriorate between the glass and the window frame. It's more frequent during winter, when the temperature is lower. This makes it easier for condensation to form. The most likely cause is a defect in the spacer used between the window and the frame. The spacer is made up of desiccant which is extremely absorbent and absorbs any excess moisture.

The issue is that when the desiccant is saturated, it begins to break down, and eventually moisture can start to leak through the gap between the glass units. This can cause condensation and water to build within the gap, which is difficult to clean out.

The positive side is that many trustworthy window manufacturers will provide an assurance on their products. They should replace the glass and window unit if it has been damaged by condensation. Make sure to report any issues as soon as you can to your window installer so that the condensation can be repaired as fast as it can to avoid further damage.

Before you begin it's best to clean the rabbet. This is the area around where glass is placed. Clean it off and then apply an oil coat of linseed to the rabbet, which will allow the new putty to stick to the frame securely.

After the frame is cleaned and the rabbet prepared It's time to put together the replacement pane. Find the height and width of the opening in both directions, then order a piece of double-strength glass that's 1/8 inch shorter in both directions. You'll also need glass points, which are metal triangles which hold the glass in place.


After removing the window sash and the pry-bar flat, use it to carefully pry the sash free of the moulding of wood. It is possible to scrape old glazing off using a utility blade or chisel. Use the heat gun to warm any putty that cannot be easily removed. This will make it easier to peel it off.
