Double Glazed Windows Repairs

There are many reasons your double-glazed windows may need repairs, from condensation between panes, to draughts and dropped or sagged frames. The majority of these issues are fixable.

Try lubricating the hinges, handles and mechanism of your door or window in case it is hard to open. This is usually a cheap solution that is quick and easy to fix.

Broken Panes

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

The first step is to get rid of any broken glass. Start by placing a low-cost glass cutter in an appliance store beneath the broken pane. It's worth lubricating this tool's cutter with lightweight oil before you begin. This will stop the glass from breaking too easily. The ball-shaped end of the tool can be used to break the fragments. They should fall off fairly quickly.

After the glass has been removed, scrape off any glazing compound that is old from the recess area of the frame. This will reveal the glazier's clips and pins that keep the glass in place. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is made of wood the glazier's points could be reused if they're in good condition.

You'll need to prepare the surface of the frame to be re-glazed. Apply a continuous strip of compound to the recess using the caulking tool. Make use of a high-quality glue such as a glazier's compound that is contained in a cartridge or a conventional compound that is sold in a can. Allow it to dry before inserting the glass. If the frame has metal clippings, they must be reinstalled too. Reinstall the divider muntins.

Condensation

Condensation is a frequent issue that double-glazed windows may experience, especially in the winter months. This is usually caused by too many moisture levels in your home. Warm air meets cold glass and condenses to droplets of water. These droplets then accumulate in the corners or frame of the window repair. You can avoid this by opening your windows more frequently and improving ventilation with extractor fans, and running dehumidifiers. If condensation remains a problem, it's important to get a professional to get to the root of the issue and repair or replace your windows if needed.

Condensation on a double-glazed window is a sign that the seal has failed. This is because the vacuum seal that was applied by the manufacturer may break down in time, allowing cool air to flow between the panes. This could lead to fogging of the window and eventually mold growth if it is not addressed quickly enough.

A hairdryer can be used for a quick way to eliminate excess moisture. However, this is just an interim solution and should only be only used as the last resort. If the condensation has been allowed to sit for too long you may be experiencing mold or dampness in your home, which must be dealt with by a professional.

For a more long-term solution you can have your double-glazed windows resealed by experts. They'll remove the affected pane of glass, clear the gap and pipe in hot air to evaporate any lingering moisture. During the process, they will also inspect for any damage or growth of mildew, mould or mildew and then perform a draught proofing treatment to ensure that your windows are functional and energy efficient.

Draughts

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

Misted double glazing is a sign the seals inside your sealed unit (sometimes called a DGU) have been blown. The unit is comprised of two panes of glass that are separated by the spacer bar to create an insulating gap and then filled with gas, like argon, to make the window airtight. If the seal has blown it allows water vapour to get into your space through the gap, creating condensation between the panes that is not able to be cleaned off.

This is a straightforward issue to repair and windows can be easily repaired by professionals using the proper tools. The specialist will use an instrument that is designed to push in the new seals. This is usually quicker than doing it manually. The tools also have a pointed end which is useful for pushing seals into the corners.

A professional could be able to seal your windows' by drilling a small opening in the window, and adding a desiccant or putty. This is less expensive than replacing your double glazing and will still provide you with a air-tight system for draughtproofing.

Faulty Hinges

Misted double glazing is a frequent problem that many people encounter. It can be caused by a broken seal or crack in the glass or an issue with the frame or mechanism. The good thing is that this can often be repaired. Usually, this means making a new seal between two glass panes. The new seal will prevent condensation, draughts and leaks from happening.

Contact the company from which you bought your windows and tell them of any problems when you discover them. It is important to notify the company in writing and ask for confirmation that they received your message. Having everything in written form will be helpful later if any disputes arise, since it will be easier to prove that you did indeed complain.

In some cases, a window repair specialist will drill the gap in your windows to draw moisture out and create a new seal. However, this is generally only a temporary solution and won't stop the moisture from returning. In addition, it might be possible to replace the glass unit itself to ensure that it is watertight.

Be aware that you should only attempt DIY fixes if your skills and knowledge are sufficient. Super glue or other DIY solutions could cause more long-term damage.

Broken Seals

Window seals, also known as insulation gas fills, are what hold double-glazed windows in place. They are susceptible to damage due to many elements, including weather conditions, age and power washing. It is important to recognize the signs and the best way to repair them.

When a window seal fails, it allows humid air to get into the two glass panes and create fog. This is a common problem that can also make the window appear distorted. Once the seal fails it is when any argon or other inert gas will be removed from the glass, thereby reducing its insulating properties.

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

If the IGU (insulated unit) is beyond repair, a glazier can replace it. This is usually the most cost-effective solution and is a great option if you're seeking an option that lasts for a long time. It is best to choose a company who offers warranties on replacement windows. This will ensure that any issues that you might encounter are covered. You can be sure that your investment will provide the best results. You can also try to avoid this problem by choosing a premium window and following the manufacturer's care instructions. This will extend the life of the window and decrease the amount of repairs.
