Double Glazed Windows Repairs

There are many reasons your double glazed windows might need repairs including condensation between panes to draughts and dropped or sagged frames. Many of these issues can be resolved.

If your window or door is difficult to open, consider oiling the hinges, mechanism and handles. This is a quick and affordable fix.

Broken Panes

When a window is damaged and shattered, it loses its insulation and may cause drafts. If the muntins which divide the glass panes are broken, water can leak between them causing condensation and mildew, as well as mould. This can 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.

Firstly, you'll need to take the broken glass off. Start by placing an inexpensive glass cutter in an appliance store beneath the broken pane. It's a good idea to grease the cutter with a light oil before you begin. This will help prevent the glass from breaking too easily. Then, you can utilize the tool's ball-shaped end to loosen the fragments and the glass should break away quickly.

Scrape any old glazing compound out of the frame's recess once the glass is removed. This will expose the glazier's point and metal clips that hold the pane in place. If there's evidence of corrosion, these should be replaced with new ones. If the window is wooden the glazier's gilder's points can be reused if they're intact.

You'll need to prepare the surface of the remaining frame for reglazing. Using a caulking gun, apply a continuous strip of compound along the inside edge of the recess. Use a high-quality putty such as glazier's compounds that is contained in a cartridge or a conventional compound sold in a can. Dry it out before installing the glass. Reinstall the metal clips if they are on the frame. Reinstall the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, particularly in winter. It's typically caused by too much humidity in the home, with warm air meeting cold glass. This then turns into water droplets, and then collects in the corners of your windows or across the frame. You can stop this from happening by opening your windows more often, improving ventilation with extractor fans, and utilizing dehumidifiers. If condensation remains a problem, it's important to get a professional to get to the bottom of the issue and repair or replace your windows when needed.

It's also important to remember that condensation on a double-glazed window could be a sign of a failing seal. This is because the factory-applied vacuum seal will be damaged in time and allow cool air to make its way between the panes. This can cause the window to fog up and eventually develop mold if it is not addressed promptly.

For a quick fix to condensation, you can try using a hairdryer to dry up the excess moisture. But, this is only a short-term solution and should be used as a last option. If the condensation is left for a long time it could be looking at mould or dampness in your home, which must be addressed by a professional.

Professionals can reseal your double-glazed window repairs to provide a longer-lasting solution. They'll remove the damaged glass pane and clean the gap. They'll then pipe hot air into the space to evaporate any moisture. During this process, they'll also look for signs of damage, mould or mildew growth, and then apply a draught-proofing treatment to ensure that your windows are operational and energy efficient again.

Draughts

Rubber seals can wear out in time and create drafts between the two panes. It's an easy fix to replace the gaskets, which will create an airtight seal. This will allow warm air in your home and the colder air out, thereby saving you money on your energy bills.

Double glazing that has mist could be an indication of blow-blown seals. The unit is comprised of two panes of argon-filled glass separated by a spacer to create an airtight window. If the seal has been blown, water vapour will enter your space through the gap. This will create condensation between the glass panes which can't be sucked out.

Fortunately, this is an easy issue to fix and the windows can be replaced very quickly by experts who have the appropriate tools and know how to do it right. The specialist will use an instrument that is designed to push in the new seals. This is generally faster than doing it manually. The tools also come with a pointed end that can be helpful for pushing seals into the corners.

In certain cases an expert might be able to "reseal your windows' by drilling a small opening into the window and adding a special desiccant material or putty. This can be more cost-effective than replacements and will give you an effective draught-proofing system for double glazing.

Faulty Hinges

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

Contact the company from whom you purchased your windows and inform them of any issues as soon as you notice them. You should notify the company in writing and request confirmation that they have received your notice. Making sure that everything is in writing will help later on should any disputes arise, since it is easier to prove that you actually complained.

A window repair professional might be able to drill a hole in the gap between your windows to eliminate moisture and create the seal. However, this is typically only a temporary solution and will not stop the return of moisture. It may also be possible to replace just the glass unit, which will make it watertight.

Remember that you should only attempt DIY fixes with the knowledge and skills you have are sufficient. Super glue or other DIY solutions could cause more damage over the long term.

Broken Seals

Window seals, also known as gas fills, are what keep double-glazed windows in place. Many factors can cause them to break, including the weather, age, and power washing, so it's essential to be aware of what signs are and how to repair them.

If a window seal fails, humid air can seep between the two panes glass, creating fog. It's a frequent issue and can cause the window to look visually altered. If the seal is damaged, any argon or other inert gas will be removed from the glass, diminishing its insulating properties.

A broken window seal can be repaired by replacing it with a a new one by an experienced glazier. This is costly and might not be able to resolve the fog issue. Some companies offer defogging services that involve putting an air pump inside the window frame to remove the moisture and make the glass clear. However this method isn't 100% reliable and cannot replace any inert gases, meaning that the fog could come back.

A glazier may also replace the entire IGU (insulated glass unit) when it's beyond repair. This is typically the most cost-effective solution and is a great option if you're looking for 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 problems you may have are covered. This means that you can be assured that you'll get the maximum value for your investment. Alternatively, you can try to avoid this issue by choosing a high-quality window and following the manufacturer's maintenance instructions. This will extend the life of the window and decrease the number of repairs.
