7 Helpful Tips To Make The Most Out Of Your Repairing Double Glazed Windows
Repairing Double Glazed Windows

Double glazing is an investment that will benefit your home. As time passes, it will cause problems such as misting or condensation.

This can be caused by a variety of reasons but is usually down to the seals no longer being air-tight, causing a loss in the gas that is used to insulate between the glass panes. It can be helpful to know how to repair double glazing.

Broken Panes

A cat's claw, a stray lawnmower ball, or a stone that is thrown can cause a double glazed window to break. If this happens the cold or hot air can move more easily between the two panes of glass which makes your home less well-insulated and increasing your energy costs. If both windows are shattered then it's time to contact an expert to repair the windows.

If one of the panes is damaged but is not completely broken it could be possible to repair. The first step is to take the old pane from the frame wearing gloves and work glasses. Remove repair timber windows that is loose from the cracked edges of the glass using the painter's tool, which can be warmed by the help of a heat gun. Use aluminum foil to shield the glass from cracking as the putty is being removed.

When the frame is ready for the new pane, you need to lubricate the cutter on a cheap glass cutting tool -- found in many hardware stores -- using light oil such as WD-40. Score the glass around the perimeter, approximately one inch from the edge. Then, gently move the glass into the rabbets, the grooves that are shaped like an l, in the window frame in which it is placed. Then, use the tool's chiseled tip to remove any excess putty from the edge of the glass.

After the new pane is installed, press the glazier's facets into the frame every six inches around the edge where it joins the glass. Then apply another cord of glazier's compound to the frame-glass joint and smooth it out using the putty knife. If your windows are metal paint the joints using a primer that prevents rust. It is designed specifically for the type of metal you have.

Cracks

Although it is not common, a sudden crack in your double glazing can occur - particularly in older windows. The reason for this is usually due to the difference in pressure between the two panes glass, caused by extreme temperature variations. This is why it's essential to keep your blinds closed during hot weather, and not open them too much when the sun is shining - this prevents excess heat from building up between the two glass panes.

To prevent cracks from occurring on your double-glazed windows, ensure that the frames, particularly the hinges, locking mechanisms and handles are secured. Double glazed windows should be simple to open and close, without sagging or sticking. Oiling the hinges and mechanisms could assist. You can also adjust the screws and locks so that they are tight enough.

Be aware that a damaged glass window could be dangerous. If you notice shards of glass on the floor and a crack in the double glazing, it is recommended to contact an emergency glazing expert. It's better to replace the broken glass than try and repair it.

If you see condensation between the two panes, it is an indication that your seals aren't working properly and need to be fixed immediately. A reputable glazier can drill into the sealed unit to inject or pump in dry agent (typically a desiccant) to remove any moisture. This is a fast and inexpensive solution. Be aware that this is temporary solution and you'll have to replace the windows in the near future.

Condensation

Condensation can be a problem with older double glazing. It happens when air moisture is drawn into the gap between the panes and condenses during the night. This is a natural occurrence that does not indicate any issues with the windows or glass. However it can be a source of frustration for homeowners since it stops the double glazing from working in the way it should.

Add vents or trickle-vents to the frame to allow air to flow, preventing condensation in your home. This will also help keep your home warm and lower energy costs over time.

A professional will usually be able to resolve the issue without replacing the entire window. They will drill tiny holes into the window to let out any moisture that has been trapped and then apply an antifog coating.

Contact the company where you purchased your double glazing as soon as problems occur. This is to allow them to send out a technician to check the situation and resolve any issues before they get worse. It is also a good idea to keep all communications in writing, such as an email or letter, since this will make it easier to challenge any claims in the future.

It is possible to fix some things yourself, but it is typically quicker and more efficient to hire an expert. This is particularly true for any problems that require specialist tools. A professional can also provide a guarantee on their work, which you may not get if you try to fix the double glazing yourself.

Draughts

Double-glazed windows are becoming more popular due to their efficiency in energy use, reduce the noise levels in the home, and shield furnishings from UV rays. They can also help to reduce condensation, which is a common cause of mould. If they are not properly installed, air can easily leak through the gaps in between the glass panes, leading to the air to draught.

In double glazed windows, two glass panes are separated by a spacer bar and the gap is then filled with an insulating gas. The spacer bars usually contain a desiccant which helps to draw moisture from the gap, which prevents the formation of condensation inside. However, when the desiccant is no longer able to remove moisture from the spacer bar, it's possible for condensation to develop between the glass panes. This is a typical issue with double glazing that's been badly made. However, it can be easily fixed by drilling holes in the glass or spacer bar and inserting humidifiers.

The space between the two panes of glass in a double-glazed window acts as an insulation by limiting the transfer of cold air from outside into your home. Filling the gap with an inert gas like argon, could enhance the insulation properties more.


Double-glazed windows cost more money to install than single-glazed windows, but are often worthwhile as they reduce your heating and cooling costs, shield your furniture from UV damage, and increase the value of the property. If you are considering installing double-glazed windows in your home, work with an experienced installer like Thermawood. Their retrofit double-glazing system allows you to take advantage of a premium IGU without removing your existing frame and the cladding.

Replacement

Double glazing offers numerous benefits to homeowners. it increases energy efficiency, reduces noise and condensation. It can also help to reduce the risk of draughts and mould forming on windows. They aren't indestructible and, in some cases, problems may occur. Repairing most problems with double glazing rather than replacing them, which will save you money and the inconvenience of having new windows installed.

One of the most common issues that people who own double glazing face is the need to repair a leaking window seal. If this is the case it is essential to get in touch with a professional to arrange for an installer of windows to visit and make the repairs needed.

Another issue is when windows become difficult to open or close. This may be due to heat, or because the mechanism has become stiffer as time passes. Try cooling the mechanism and lubricating handles or hinges if this is the problem. It may also be that the frame is dropping or sagging and requires realignment.

The misting can be easily fixed. This happens because the rubber seals that keep the two glass panes together wear out with time. This is typically caused by the frames shifting in a slight manner as they age and compacting the specific packaging material that holds them in place, which results in one or both panes of your double glazing shifting and breaking the seal.

Misting can be corrected by drilling into the affected glass and removing moisture from inside. This is only a temporary solution and must be repeated. The best long-term solution is to install trickle vents into your frames, which allows fresh air to enter but won't let any of the warm air escape.
