If you are wondering how to fix my Double glazing repairs London, there are some basic solutions you can try. Some of the problems that you may encounter include condensation on the outside of the glass, fog between the panes, and faulty seals. You can also try oiling the mechanism, which may help to fix the problem.

The Condensation On The Outside Of The Glass

Among the most common problems that homeowners have with double glazing is condensation on the outside of the glass. This can be an unpleasant and unsightly problem. However, it can also be a sign of good thermal efficiency. Luckily, there are a number of ways to deal with condensation in your windows.

The first step is to determine where the condensation is coming from. Condensation occurs when the temperature of the exterior glass pane is lower than that of the interior pane. As the sun rises, this condensation goes away. However, it’s important to remember that this is a natural occurrence and is not a sign of a failing double glazed window. It happens because the outside air temperature falls during the night. As a result, the morning dew condenses on the cold glass surface.

Fog Between The Panes

A foggy window is caused by condensation between the window panes. This causes the window to look cloudy and can also indicate that there is water getting into the window. Condensation between window panes can also cause heat or cold to leak into the house. If you notice a condensation between your window panes, it’s a good idea to contact a double glazing repair company to replace the window panes.

The first step in removing fog from double-pane windows is to replace the gasket. A professional glass shop can perform this task for you, or you can try to do it yourself with clear caulk. However, you should be aware that you could easily end up cracking the glass if you do this yourself.

Faulty Seals

Faulty seals are one of the most common problems with double glazing. These elements are responsible for keeping out the cold air and keeping heat in during the winter and cool in the summer. A faulty seal can lead to a leaky window, but there are ways to repair or replace them.

The first sign of a faulty seal is condensation between the window panes. When the seal fails, cold air can leak around the window and into the house. A faulty window seal will also cause a milky white appearance to the window glass. Also, a broken seal can cause fogging, which is most noticeable when the indoor temperature is significantly different from the temperature outside.

Oiling The Mechanism

One of the most important things to do when performing double glazing repairs is oiling the mechanism. This will prevent the moving parts from becoming stiff and breaking down, so make sure to do it regularly. You should also clean the locks periodically, so they last longer. If they are not cleaned, they can grind against the frame, damaging the locking mechanism. If you have trouble with the locking mechanism, contact a professional glazier.

When oiling the locking mechanism of your UPVC windows, be sure to lubricate all moving parts to prevent moisture from getting into the window. You can apply the lubricant using a silicone spray. Just make sure to apply it in a way that it will cover all moving parts without causing any damage. You can also lubricate the hinges and the non-moving parts of your window.

Replacing The Frame

In some cases, it might be necessary to replace the entire frame of a window, particularly if it has major cracks or breaks. If the window is made from plastic, you may need to replace the plastic frame to repair a major crack in the glass. Alternatively, you can install a new window insert and keep the existing frame and trim.

First, you’ll need to remove the sash and glass from the window. You can then repair or replace the frame using various techniques. If the wood frame has rotted, you can either fill it with wood or replace it completely. The repair process smoothes out the material of the frame to produce a more attractive appearance.


The cost of double glazing repairs can vary depending on the severity of the damage. If your windows are cloudy or misted, the first thing you should do is call a professional double glazing repair service to fix them. They can replace the windows in the same way as the original windows or repair them if necessary.

Repairs on double glazing can vary in price depending on the materials used. The quality of individual parts can also affect the cost of repairs. For instance, repairing the glass unit may cost a lot more than fixing the hinges, lock, or door handle.
