Double Glazing Window Repairs
Many homeowners face recurring double glazing issues, such as broken handles or locks, condensation between the panes and draughts. Fortunately, most of these issues can be fixed without the need to purchase new replacement windows.
Double glazing that is misted generally means that the sealed glass unit needs to be replaced. This is often cheaper than replacing the window frame.
Broken Glass
Modern double-paned windows are easily cracked by a pebble thrown from a lawnmower, or blown branches. Usually, just one pane is damaged, but the entire window could require replacement, depending on the type of glass and whether it has special coatings or insulation. It is not difficult to repair broken glass, but for the best results, you'll need to buy an IGU (insulated unit) at your local glass shop.
Wear protective gloves and a mask while handling broken glass. A single piece of glass broken can cause serious cuts so you should be extra careful to safeguard yourself. The broken pane may be held in place with glass or putty, which must be removed. You can do this with a utility knife, but the use of a hammer or chisel could be required to remove the old putty. Cover the area with a towel to catch any shards of glass that may fall.
Make use of a heat gun prior to attempting to remove the old caulk, if it remains in place. Then cut through the caulk using your knife. If the frames are equipped with wood stops to keep the panes in the frame, you will need to use a pliers with a long nose or a hammer to take out the stop.
After the old glass has been removed, and the frame has been emptied and cleaned, wipe it clean with a damp rag. Then, you can measure the frame opening to determine the size of your new glass. You will also need a new set glass points and a double-faced glazing tape.
A glazier's knife or a putty knife is required to create the new putty. It has to be thicker than the norm because of the increased thickness of the glass. Include linseed in the putty to ensure it stays soft. Apply the putty to the glass using your thumb after it has been roll. After the epoxy has set and dried, soak a rag in acetone to clean the edges of both the frame and glass. This will remove any epoxy that is raised above the edge.
Condensation Between the Panes
Double glazing is often plagued by condensation between window panes. It can make the windows appear foggy and milky, and it can cause mildew or mould growth around sills, frames and sealants. If not treated, it could cause the frame and sash to deteriorate which can reduce the energy efficiency. If condensation becomes a major issue it will need to be addressed as soon as possible to prevent further damage and to improve the appearance of your windows.
Condensation can occur either inside or outside of the double-glazed unit. However, it is most likely to happen between the glass panes since that's the place where insulation is. Condensation inside is a sign that you're living in humid air and is easy to fix by dehumidifying your home. Condensation on the outside of your windows is a bigger issue, and is usually caused by a broken window seal.
You should contact the company who installed your double-glazed windows if you notice condensation in the glass panes. They can check for signs of failure and damage on the seals and units and may be able perform a resealing procedure to improve the thermal efficiency of the windows.

If you have old double-glazed windows and you have condensation between the panes, it's likely that the seal has failed. The seals are constructed of silica gel, a substance with a large surface area and it is able to absorb water vapor efficiently. As the seal wears down it allows moisture to get into the gap between the glass panes. This will create an opacity that you will not be able remove.
Draughts
Double-glazed windows are made up of two panes separated by an air space. This is done to improve the efficiency of energy and sound insulation. If the seals fail, moisture could be introduced and cause condensation. Foggy windows result. In this situation the glass must be replaced.
Another issue that is common is doors or windows that are difficult to open and close. This can be caused by a slight warping in the frame or defective hinges and mechanisms. In some instances, lubricating the hinges or mechanism could aid. If the issue persists, it's worth getting in contact with the company who sold you the windows to find out whether they offer repair or replacement services.
Doors and windows that are hard to close and open could allow heat to escape your home and also create draughts. This is not only a waste of time and money but can also be dangerous for you or your family. This leaves your home vulnerable to burglars who aren't you and you could end up paying more on your heating bill than you need to.

This is a common issue that we encounter when performing double glazing repairs. It is, however, a simple fix. Simply clean the frames and the glass with a damp cloth to remove any dirt or dust, then use a dehumidifier to dry the area completely prior to sealing the window.
Cracks in the sash or frames can be fixed easily by applying a strong-hold tape over the crack. It is best to make sure that the tape is thick enough to hold the crack in place but don't make it too thick or it'll fall off. Use a strip of packing tape or masking tape on both sides of the glass. For more severe cracks it is possible to use a stronger solution like expanding foam.
