Broken Panes

When a window is damaged it loses its insulation properties and may cause drafts.

It is best to have a professional repair window the damaged window in order to get the most effective seal and energy efficiency.

The first step is to remove any broken glass. Start by placing a protective drop cloth underneath the window that has been broken and cutting around the edges of the pane with an inexpensive glass cutter (available in a majority of hardware stores). Before starting, you should lubricate the cutter of this tool with a light oil. This will prevent the glass from shattering too easily. You can then make use of the tool's ball-shaped tip to loosen the fragments, which should come away quickly.

Once the glass is removed, scrape away any glazing compound that is old from the recess of the frame. This will reveal the glazier's facets and metal clips that keep the pane in the frame. Replace them if you notice any corrosion. If the window is constructed of wood the glazier points can be reused if they are still in good condition.

The surface of the remaining frame will need to be prepared for reflazing. Using a caulking gun, apply a continuous ribbon of compound around the inner edge of the recess. Use a high quality putty, such as Glazier's compound in cartridge. Let it dry before reinstalling the glass. If the frame has metal clippings, they should be replaced as well. Finally, reinstall the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, particularly during winter. This is usually caused by too many moisture levels in your home. Warm air is absorbed by cold glass and condenses into droplets of water. These droplets then accumulate in the corners and frame of the window.

This can lead to fogging of the window, and eventually mold growth if not addressed quickly enough.

Hairdryers can be used for a quick way to eliminate excess moisture. This is only a temporary solution and should only be used as a last resort. If you allow the condensation to sit for too long, it could lead to mould or dampness in your home. This issue should be handled by an expert.

As a longer-term solution, you can have your double-glazed windows resealed by experts. They'll take off the affected pane of glass, clean out the gaps and pipe into hot air to evaporate any lingering moisture. During this process, they'll check for damage, mildew or mould growth and repaired apply an draught-proofing procedure to ensure that your windows are operational and energy efficient again.

Draughts

As time passes, the rubber seals around the edges of your glass insulated can break down and this can create a draught in space between the two panes. It is simple to replace the gaskets, which will result in an airtight seal. This will keep warm air inside your home, and cooler air out. You'll save money on your energy bills.

Misted double glazing is a sign that the seals in the sealed unit (sometimes called a DGU) have been blown. The unit is composed of two panes of glass filled with argon separated by a spacer to form an airtight window. If the seal has blown it will allow water vapour to pass through your home through the gap, causing condensation between the panes that cannot be wiped off.

This is a straightforward issue to repair upvc window, and windows can be quickly repaired by professionals using the proper tools. The specialist will use a tool designed to push the new seals into position and is generally faster than doing it by hand. These tools feature an edge that can be used to push the seals into corners.

In certain situations an expert could be able to "reseal' your windows by drilling a small hole into the window and then putting in a special desiccant material or putty. This is a less expensive option than replacing your double-glazed windows and will still provide you with an effective air-tight system for draughtproofing.

Faulty Hinges

Many people have encountered misted double-glazing. This can be caused by a cracked or broken glass or frame or even a broken seal. The good thing is that this is often solved. Normally, this involves creating an entirely new seal between the two glass panes. The new seal will help prevent condensation, draughts, as well as leaks.

Broken Seals

Double glazed windows are held in place by seals on windows or gas. They are susceptible to damage due to a variety of elements, including weather conditions, age, and power washing. It is crucial to know the symptoms and how to repair them.

If a window seal is damaged, it allows humid air to seep in between the two glass panes and create fog. This is a common issue, and it can also cause the window to look visually disoriented. When the seal fails it is when any argon or other inert gas is removed from the glass, thereby decreasing its insulation properties.

A damaged window seal can be fixed by having it replaced with a new one by an experienced glazier. This can be expensive and may not solve the fog issue. Certain companies offer defogging services that involve putting a special vacuum pump in the window frame to eliminate the moisture, leaving the glass clear. However this method isn't foolproof and doesn't replace any inert gas, and the fog can come back.

If the IGU (insulated unit) is damaged beyond repair, a glazier can replace it. This is the most cost-effective solution and is a good choice if you are seeking a long-term solution.
