Double Glazed Windows Repairs

Double-glazed windows may require repair for a variety of reasons like condensation between the panes, draughts or sagging frames. Many of these issues are fixable.

Try applying lubrication to the hinges, handles, and mechanisms of your window or door in case it is hard to open. This is usually a low-cost, short-term fix.

Broken Panes

When a window pane is broken, it loses its insulation properties and may cause drafts. If the muntins that separate the glass panes are broken, water can get in between them and cause condensation, mould or mildew. This will make your home less efficient in energy use. A broken window is best repaired by an expert to ensure that you get the correct seal and maximum energy efficiency.

First, you'll need to take out any broken glass. Start by placing a protective drop cloth beneath the window that has been broken and cutting around the perimeter of the pane using an inexpensive glass cutter (available in a majority of hardware stores). Before you start, make sure to lubricate the cutter with a light oil. This will stop the glass from breaking too easily. The ball-shaped tip of the tool can be used to loosen the pieces. They should fall off fairly quickly.

Once the glass is removed, scrape off any glazing compound that is old from the recess area of the frame. This will expose the glazier's clips and pins that hold the glass in the frame. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is constructed of wood, the glazier points can be reused if still in good condition.

The surface of the remaining frame needs to be prepared to allow re-glazing. Apply a continuous strip compound to the recess with the caulking tool. Use a high-quality putty such as a Glazier's compound in cartridge. Let it dry before installing the glass. Install the metal clips if they are on the frame. Install the dividers.

Condensation

Condensation is a frequent issue that double-glazed windows face, especially in the wintertime. This is usually caused by high levels of moisture within your home. Warm air meets cold glass, which condenses into droplets of water. These droplets then accumulate in the corners or frames of the window. You can prevent this from happening by opening your windows more frequently and enhancing ventilation by installing extractor fans, and running dehumidifiers. If condensation persists, you should call a professional who can diagnose the issue and fix or replace the windows if required.

It's also important to remember that condensation on windows with double glazing can actually be an indication of a failing seal. This is due to the factory applied vacuum seal will break down over time and allow cool air to move between the panes. This could lead to fogging of the window and eventually, mold growth if not dealt with quickly enough.

A hairdryer can be used as a quick solution to get rid of excess moisture. However, this is just an interim solution and should only be used only as a last option. If the condensation is left for a long time you could be looking at dampness or even mould in your home, which must be addressed by a specialist.

Professionals can seal your double-glazed window repairs (http://0553721256.ussoft.kr/g5-5.0.13/bbs/Board.php?bo_table=board01&wr_id=288928) for a more permanent solution. They will remove the affected glass pane, clean the gap and pipe hot air into the area to evaporate any moisture. During the process, they will also look for any damage, mildew or mould growth, and perform an air draughtproofing treatment to ensure that your windows are functional and energy-efficient once again.

Draughts

As time passes by, the rubber seals around the edges of your glass are likely to break down and this can create a draught in the space between the two panes. This is usually a minor problem that can be solved by replacing the gaskets and this will create a strong and airtight seal. This will keep warm air inside your home, and colder air outside. You can reduce your energy bills.

Double glazing that is misted may be a sign of blow-blown seals. The unit consists of 2 panes of glass that are separated by an insulating bar that creates an insulating space. It is then filled with gas, like argon to make the window airtight. If the seal is blown water vapour can enter your space through the gap. This can cause condensation between the glass panes which can't be sucked out.

Fortunately, this is an easy problem to fix and the windows can be replaced quickly by specialists who have all the right tools and know how to do it properly. The specialist will use an instrument that is designed to push in the new seals. This is usually quicker than doing it by hand. The tools also have a pointed tip that can be helpful to push the seals into the corners.

In some cases professionals may be able to 'reseal' your windows by drilling a small hole into the window and adding a special desiccant material or putty. This is a less expensive option than replacing your double glazing and will still provide you with an effective air-tight system for draughtproofing.

Faulty Hinges

Misted double glazing is a common issue that many people face. This can be caused by a cracked or broken glass or frame or even a damaged seal. It is possible to fix this problem. Usually, this means making a new seal between two glass panes. The new seal will stop leaks, condensation and draughts from occurring.

You should contact the company from which you purchased your windows, and tell them of any problems when you spot them. Make sure to put this in writing and ask them to confirm that they have received your notification. Writing everything down will make it easier to resolve any disputes arise, as it will be easier to prove that you did indeed complain.

A window repair expert might be able to drill a hole in the gap between your windows to eliminate moisture and make a seal. However, this is typically only temporary and won't stop the moisture from returning. Alternatively, it may be possible to replace the glass unit itself which will ensure that it is watertight.

Broken Seals

Double-glazed windows are held in place by window seals or insulation gas. There are a variety of reasons that can cause them to break, like age, weather conditions and power washing, therefore it's essential to be aware of what symptoms are and what to do to fix them.

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

A broken window seal can be fixed by having it replaced with the new one by an experienced glazier. This can be costly and may not solve the fog issue. Certain companies offer defogging services that involve putting an air pump inside the window frame to remove the moisture and leave the glass free of fog. This method is not foolproof, and it doesn't replace inert gasses, meaning that fog may return.

If the IGU (insulated unit) is beyond repair, a glazier can replace it. This is the most cost-effective solution and is a good choice if you are looking for a long-term solution. It is recommended to choose a company with a guarantee for replacement windows to ensure that any problems are covered. You can be certain that your investment will produce the best results. You can also get rid of the issue by choosing a high-quality product and following the care instructions given by the manufacturer. This will prolong the life of the window and cut down the number of repairs.
