How to Repair Double Glazing

Seals

The seals used in double glazing are an important element of the overall insulation and energy efficiency of the windows. They are located between the glass panes of uPVC frames and create an airtight shield that helps keep out rain and wind, drafts and condensation which can cause damp on windows and wall sills. In addition, the window seals help keep warm air in and cold air out, which can drastically reduce heating costs.

It is not unusual for window seals to break down. This is usually due to exposure to extreme weather conditions and elements like high winds, snow and rain. However, it could also be due to an improper installation or the use of chemicals like paint strippers, which can damage the rubber.

If the window seals fail, humidity and moisture may seep through the glass panes causing fogging or misting. Double glazing may lose its insulation properties if the inert gases between the panes is no longer present.

It's possible to make some DIY double glazed window seal repair if you are aware of what to look for. However, it's generally better to call an experienced window repair service to do the work. They can repair the windows to restore their insulating and energy efficient qualities as well as tackle any unsightly condensation that has formed between the glass panes.

Glass

Double glazing can have problems. The most frequent issue is misting. This occurs when the seal is broken between two panes, and moisture accumulates.

The procedure for repairing it involves removing the affected pane, blowing air through the gap to eliminate any remaining moisture, and then forming an entirely new seal.

Double-glazed windows can be made from a wide selection of glass. Some of the glass is clear like mirrors or safety glass, but it is tempered for durability and safety. Other kinds of glass are coated to improve their properties. This can include solar control glass which reduces glare and blocks heat transfer; extra-clean glass that is self-cleaning and stain-resistant; and the chromogenic glass, which alters transparency according to temperature.

Some manufacturers also offer high-efficiency double glazed units. These units make use of special films and insulated glass to regulate the internal temperature to ensure that cooling and heating systems do not have to be as laborious.

The frames that house the double glazing are constructed of materials like wood and plastic which can be damaged in many ways. Frames that are damaged can allow cold air to penetrate your home, which can increase your heating costs. As time passes, frames be twisted and warped.

A common indication that your double glazing requires repair is the build-up of condensation between the glass panes. This is usually a sign that the seal has failed and allowing air to move between the panes. This could cause the moisture to drop and make your room feel draughty. This issue should be addressed as quickly as possible to avoid further issues.

If the window is not damaged or cracked, it may not be necessary to replace it. In fact the frame could be in perfect condition, which is why it's more economical to replace the glass unit within the window.

Many companies provide same-day double glazing repair services, but you should know what you require before requesting the quote.

Locks

A reputable tradesperson will install a window lock, whether you are installing new windows or repairing double glazing.

A popular option is an Espagnolette system that has mushroom headed bolts that engage behind locking points on the frame. They are typically installed into uPVC doors and windows but can be added to aluminium and timber.

Other locks are made for limiting the amount of opening windows. If you have a casement type window, think about installing a Canzak Window Restriction Cable, which works like the chain lock used for doors and can be secured on either side of the opening to prevent it from opening too wide. It's also simple to install and one of the few locks that can be used on casements.

A hinged wedge lock could be used to stop the lower sash of sash windows from being raised enough to permit an intruder to gain access. Cut a strip of wood to the width of the channel which operates the lower sash. Fit it into the frame, and then affix it to the wall and frame.

You could also add keys to your casement or sash window. These are more robust than latch locks and are usually paired with them to ensure that windows are secure. They are on the sides of windows and are used on double glazed window repairs and single-hung windows as well as sliding ones.

There are other ways to make your double glazed windows more secure, such as adding a shoot bolt locking system that has bolts that are shot from both sides of the frame to create an extremely sturdy lock. These are usually offered as an upgrade option, and are suitable for residential and commercial usage.
