How to Repair Double Glazed Windows
Double glazed windows often come with 10 or 20 years warranties so be sure to check what cover you have. Repairing double glazing can be cheaper than replacing it, and can save you money and energy.
If your double glazing has started to mist it is most likely that the sealant between the glass panes has failed. This can happen when windows are damaged or worn out. It could be expensive to replace.
1. Cracked or Chipped Glass
Double-glazed windows that are damaged or cracked can cause condensation to develop between the two panes. In most cases it is required to replace the entire glass unit, particularly if both or just one of the panes has been broken. If the frame is in good condition, fixing just one glass pane might be a viable option.
Repairing cracks is simple and fast with masking tape or duct tap. One strip of tape ought to be sufficient to seal superficial cracks such as stress fractures caused by temperature fluctuations. For more serious cracks, such as those caused from the impact of the glass it is advised that the tape is extended to the entire length of the crack in order to ensure that it will keep the glass together.
Another alternative to permanent solutions is to use a solvent-based glass adhesive. Typically, it is applied to the inner and outer areas of the cracks, and then spreads using a knife. This method is more time-consuming however, it is more effective at stopping cracks from spreading.
If the cracks are serious or have been present for an extended period of time, it might be better to wait for a professional firm to repair the windows, since this could result in a more durable finish. If upvc window repairs aren't that bad and are not causing any water leaks and are not causing any water leaks, it's better to stick with the quick fixes because they can keep the cost of repairs low.
A more permanent method to fix a crack in a double-glazed window is by applying an epoxy resin that is two-part to the affected area. The glass's surface must be cleaned with a damp cloth, and then allowed to completely dry. Then, mix the resin and hardener according to the directions on the package and then apply it to the crack with a putty knife. After it has dried completely, you can paint over the putty and surrounding frame to create a seamless surface.
2. Water Leaks
Whether your double glazing has been leaking or you've noticed condensation in between the glass panes, both of these issues can often be repaired without having to replace your windows. This is because the issue isn't in the uPVC, aluminium or timber window frames themselves but rather in the IGU, or insulated glass unit (IGU) that sits between them.
The IGU is composed of two glass sheets that are separated by a bar that acts as a spacer and then filled with an insulating gas - much like a glass sandwich. The gap must be airtight to prevent cold air from getting into your home and keep your home warm. Seals in the IGU will weaken over time, and at different temperatures.
Water leaks can be detected by a number of signs including condensation on the window sill and frame, discolouration and a musty smell. It's important that you contact an expert as soon as you detect any of these signs.
If you see condensation on the surface of your double-glazed windows, it's probably due to the high humidity levels within your home. It is a natural phenomenon that occurs in winter, and isn't caused by defective double glazing, no matter how frustrating it might be.
If you see moisture between the glass panes of your double-glazed windows, it indicates that the IGU isn't performing as as it ought to. Moisture between the glass panes isn't only unattractive but also reduces the effectiveness of your double glazing because it doesn't keep the cold out and the heat in.
There are several ways this issue can be resolved, but it's generally best to leave it to experts. They will drill small openings into the glass pane affected and then inject or pump in desiccant. Then, they'll use a special antifogging solution that will stop the condensation from returning. They can then inject hot air into the gap to further dry it out.
3. Draughts
Double-glazed windows come with an airtight seal to prevent condensation from forming between the panes. However, the seal can begin to fail with time. There could be a cold draft passing through the door or window when this occurs. This can be annoying and result in a decrease in energy efficiency. If your window is draughty it is recommended to schedule an repair service to replace the seal as soon as you can.
Double glazing is a kind of window that includes two glass panes within frame composed of aluminium or uPVC. The primary component of double-glazed windows is an insulated glass panel (IGU) that comprises two sheets separated by an air space that is filled with gasses that are insulating. This creates a 'sandwich of glass' effect and helps keep your home warm and peaceful.

This is normal, however it can cause problems such as a sticking or stiff window or door. Fortunately, it's simple to solve these issues by hiring a UPVC window specialist.
Some companies will drill holes into the window and insert an desiccant to remove any moisture. This is a great solution and is cheaper than replacing the window. It is important to keep in mind, however, that the hole needs to be filled in again after six months and the moisture could return in the event that the seal fails else on the window.
A commercial product or mixture of water and vinegar can be used to remove haze. This is a much more complex method than drilling holes in the window and inserting desiccant. However, it can be very efficient and does not require any replacement.
