Double Glazed Windows Repairs

There are many reasons your double-glazed windows could require repairs, from condensation between panes, to drop or sagged frames. Most of these problems can be solved.

If your door or window is difficult to open try oiling the hinges, mechanism and handles. This is a quick and cheap solution.

Broken Panes

When a window pane is broken, it loses its insulation properties and may cause draft. If the dividing muntins also broken it can cause moisture to leak between the glass panes resulting in condensation, mildew and mould and making your home less efficient in energy use. It is recommended to have a professional repair the damaged window to ensure the best seal and energy efficiency.

Firstly, you'll need to remove the broken glass. Start by placing a protective drop cloth under the broken window, and then cutting around the perimeter of the pane using an inexpensive glass cutter (available in a majority of hardware stores). Before starting, you should grease the cutter with a light oil. This will prevent the glass from breaking too easily. The ball-shaped tip of the tool can be used to loosen the pieces. They should be removed quite quickly.

Once the glass is removed, scrape off any glazing compound that is old from the recess of the frame. This will reveal the glazier's points and metal clips that hold the pane in place. If there's evidence of corrosion, these clips should be replaced with new ones. If the window is wooden the glazier's gilder's points can be reused if they're in good condition.

The remaining frame needs to be prepared to allow re-glazing. Utilizing a caulking gun apply a continuous strip of compound around the inner edge of the recess. Use a high-quality putty like glazier's compound that is contained in a cartridge or conventional compound that is sold in a can. Dry it out before installing the glass. Reinstall the metal clips, if they are attached to the frame. Finally, install the dividers.

Condensation

Condensation can cause problems for double-glazed windows, particularly during winter. It's typically caused by excessive moisture in the home, with warm air meeting cold glass, which condenses into water droplets and collects in the corners of your windows or across the frame. This can be avoided by opening your windows more often, improving ventilation through extractor fans, and using dehumidifiers to lower the moisture levels. If condensation persists, you should call an expert who will be able to pinpoint the issue and fix or replace the windows if needed.

Condensation on a double-glazed glass window is a sign that the seal has failed. The seal that is applied by the factory could wear away over time and let cool air get between the panes. This can lead to fogging of the window and eventually mold growth if not addressed promptly enough.

Hairdryers can be used to get rid of excess moisture. However, this is only an interim solution and should be only used as an option last option. If you leave the condensation for too long, it could lead to mould or dampness within your home. This should be dealt with by a professional.

Professionals can seal your double-glazed window to provide a longer-lasting solution. They'll remove the affected pane of glass, clean out the gap and pipe into hot air to eliminate any lingering moisture. During this process, they'll examine for any the presence of mildew, mold or damage growth and carry out an draught-proofing procedure to ensure that your windows are completely efficient and energy efficient again.

Draughts

As time passes by, the rubber seals around the edges of your glass insulated can be damaged and create a draught in space between the two panes. This is typically a simple problem that can be fixed by re-installing the gaskets and this will result in a solid and airtight seal once again. This will keep warm air inside your home and cooler air out. You will save money on your energy bills.

Misted double glazing indicates that the seals in your sealed unit (sometimes called a DGU) have blown. The unit is made up of two panes of argon-filled glass separated by a spacer, creating an airtight window. If the seal is 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 fix, and windows can be easily replaced by experts using the appropriate tools. The specialist will use an instrument designed to push the new seals into position and this is normally quicker than trying to do it by hand. The tools also come with a pointed end which can be useful for pushing seals into the corners.

In some cases an expert may be able to 'reseal' your windows by drilling a small hole in the window and adding a special desiccant material or putty. This is more cost-effective than replacements and it will still provide a reliable draught-proofing solution for your double-glazed windows.

Faulty Hinges

Many people have experienced misted double glazing. It may be caused by a damaged seal or crack in the glass or a problem with the mechanism or frame. It is usually possible to correct this issue. Normally, this involves making a new seal between two panes of glass. The new seal will prevent leaks, condensation and draughts from occurring.

You should contact the company from which you purchased your windows, and inform them of any problems when you notice them. You should notify the company in writing and ask for confirmation that they received your message. Writing everything down will make it easier to resolve any disputes arise, since it is easier to prove that you actually complained.

A window repair expert may drill the gap between your windows in order to eliminate moisture and make a seal. This is a temporary fix that won't stop the return of moisture. It might also be possible to replace only the glass unit, which will make it watertight.

It is crucial to remember that you should only experiment with DIY fixes only if you have the experience and know-how required to do so. Using super glue or another type of DIY solution could cause more damage in the long run. It is always best to seek help from a professional in case you are unsure of what to do.

Broken Seals

Double-glazed windows are held in place by seals on windows or gas. They are susceptible to damage due to many factors, such as weather conditions, age, and power washing. It is essential to recognize the signs and how to fix them.

When a window seal breaks it allows humidity to seep in between the two glass panes, creating fog. This is a frequent issue that can cause the window doctor appear to be distorted. Once the seal fails, gas like argon as well as other inert gases are lost from the window, further diminishing the glass's insulation capabilities.

A professional glazier can replace a broken window seal with a brand new one. This is costly and may not solve the fog issue. Some companies offer defogging services, which involve placing a special vacuum pump in the window frame to eliminate the moisture and leave the glass clear. However, this method is not foolproof and does not replace any inert gases, so the fog may come back.

If the IGU (insulated unit) is beyond repair, a glazier can replace it. This is typically the most cost-effective option and is a great option when you're looking for a long-term solution. It is recommended to choose a company who offers warranties on replacement windows. This will ensure that any issues you might face are covered. This means you can be sure that you'll get most value from your investment. You can also avoid this issue by choosing the best quality product and following the care instructions given by the manufacturer. This will prolong the lifespan of the window and decrease the number of repairs.
