Double Glazed Windows Repairs

Double glazed windows can need repair for a variety of reasons, like condensation between the panes, draughts, or frames that are sliding. Fortunately, a majority of these issues can be fixed.

Try applying lubrication to the hinges, handles, and mechanism of your window or door in case it is hard to open. This is usually a cheap temporary fix.

Broken Panes

When a window is broken it loses its insulation and may cause drafts. If the muntins that divide the glass panes also damaged, moisture could get in between them and cause condensation and mildew, as well as mould. This makes your home less energy efficient. A window that is damaged should be repaired by an expert to ensure that you get the correct seal and maximum energy efficiency.

First, you'll need to remove any broken glass. Start by placing a protective drop cloth underneath the broken window, and then scoring around the perimeter of the pane using an inexpensive glass cutter (available at most hardware stores). It's worth lubricating this tool's cutter with lightweight oil before you begin. This will prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the pieces. They should be removed quite quickly.

Scrape any old glazing compound off the recess of the frame once the glass is removed. This will reveal the metal clips and glazier's pins that keep the glass in place. If there's evidence of corrosion, the clips must be replaced with new ones. If the window is made of wood the glazier's gilder's points can be used again if they're in good condition.

You'll need to prepare the surface of the remaining frame for re-glazing. Apply a continuous strip of compound to the recess with the caulking tool. Use a high-quality putty, such as glazier’s compound in a cartridge. It should dry before reinstalling the glass. Reinstall the metal clips, if they are attached to the frame. Install the dividers.

Condensation

Condensation is a frequent issue that double-glazed windows face, especially in the winter months. It's typically caused by too much moisture in the home where warm air collides with cold glass, which turns into water droplets, and then collects in the corners of your windows or across the frame. It can be prevented by opening windows more frequently, improving ventilation through extractor fans and running dehumidifiers in order to reduce the amount of moisture. If condensation remains an issue, it's best to call in a professional to get to the bottom of the issue and fix or replace your windows if required.

Condensation on a double-glazed 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 could cause the window to get smudged and eventually develop mold if it is not addressed quickly.

A hairdryer can be used as a quick solution to get rid of excess moisture. However, this is just temporary solution and should only be used as the last resort. If you allow the condensation to sit for too long, it may lead to mould or dampness within your home. This issue should be dealt with by a professional.

As a long-term solution, you can have your double-glazed windows resealed by experts. They'll remove the affected piece of glass, then clean the gap and pipe into hot air to evaporate any remaining moisture. In this process, they'll also check for damage, Double Glazing mildew or mould growth, and then apply an draught-proofing procedure to ensure your windows are fully operational and double glazing energy efficient again.

Draughts

The rubber seals wear out over time and create drafts between the two panes. This is usually a minor issue that can be resolved by replacing the gaskets and this will create a strong and airtight seal once again. This will keep warm air inside your home, and colder air outside. You can save money on your energy bills.

Misted double glazing is a sign the seals of 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 is blown water vapour can enter your space through the gap. This can result in condensation between the glass panes, which is not able to be removed.

Fortunately, this is an easy problem to fix, and windows can be replaced very quickly by experts who have the appropriate tools and know how to do it right. The expert will employ an instrument designed to push in the new seals. This is generally faster than doing it manually. The tools have an angled tip that can be used to push seals into corners.

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

Faulty Hinges

Many people have experienced misted double glazing. This can be caused by a broken or cracked glass frame or even a broken seal. It is possible to resolve this issue. Typically, this is done by creating a new seal between the two glass panes. The new seal will stop condensation, draughts, as well as leaks.

You should contact the company from which you purchased your windows, and let them know of any problems when you notice them. Be sure to do this in writing, and ask them to confirm that they've received your message. If there are any disagreements the fact that everything is written will aid in proving your claim.

In some instances an expert in window repair may be able to drill a hole in your windows to draw moisture out and create an entirely new seal. This is only temporary and will not stop the return of moisture. It is also possible to replace just the glass unit, which will make it watertight.

Be aware that you should only attempt DIY fixes with the knowledge and skills you have are adequate. Super glue or other DIY solutions could cause more long-term damage.

Broken Seals

Double-glazed windows are held in place by seals on windows or gas. They can be damaged by many elements, including weather conditions, age and power washing. It is essential to know the symptoms and how to repair them.

When a window seal fails it allows humidity to get into the two glass panes and create fog. This is a common problem that can make the window appear disfigured. When the seal is damaged, gas like argon as well as other inert gases are lost from the window, decreasing the glass's insulation properties.

A professional Glazier can replace a damaged window seal with a brand new one. This is costly and may not completely solve the fog issue. Certain companies offer defogging, which involves putting an air pump inside the frame of the window to remove moisture and make the glass clear. However, this method is not foolproof and does not replace any inert gases, meaning that the fog could come back.

If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is usually the most cost-effective solution and could be a good option in the event you're looking for the long-term solution. It's best to select a company who offers warranties on replacement windows. This will ensure that any problems you may have are covered. You can be assured that your investment will yield the best results. You can also try to avoid the problem by selecting an item of high-quality and following the care instructions that are provided by the manufacturer. This will prolong the life of the window and cut down the number of repairs.
