Double Glazed Windows Repairs

Double-glazed windows may require repair for a variety of reasons like condensation between the panes, draughts, or frames that are sliding. Fortunately, a majority of problems can be addressed.

Try to lubricate the hinges, handles and mechanisms of your window or door when it is difficult to open. This is usually a cheap solution that is quick and easy to fix.

Broken Panes

When a window is broken, it loses its insulation properties and could cause draft. If the muntins which divide the glass panes are also damaged, moisture could leak between them causing condensation, mould or mildew. This makes your home less energy efficient. A window that is damaged should be repaired by an expert to ensure you get a perfect seal and maximum energy efficiency.

First, you will need to take out any broken glass. Start by placing an inexpensive glass cutter from an hardware store underneath the broken pane. It's worth lubricating this tool's cutter with a light oil before you begin. This will help prevent the glass from breaking too easily. You can then utilize the tool's ball-shaped end to loosen the pieces and they should fall off fairly quickly.

Scrape any old glazing compound from the frame's recess after the glass is removed. This will expose the metal clips and glazier's pins that keep the glass in place. Replace them if you notice any corrosion. If the window is made of wood the glazier points can be reused if they're still in good shape.

The remaining frame must be prepared for the re-glazing. Apply a continuous strip compound to the recess with a caulking tool. Use a high-quality putty like glazier's compound that is contained in a cartridge or conventional compound sold in a can. Let it dry before installing the glass. Reinstall the metal clips if they are on the frame. Finally, reinstall the divider muntins.

Condensation

Condensation can be a problem for double-glazed windows, particularly during the winter. This is usually caused by high levels of moisture within your home. Warm air is absorbed by cold glass and condenses into water droplets. These then collect in the corners or frames of the window. This can be avoided by opening windows more frequently and enhancing ventilation with extractor fans, and using dehumidifiers in order to reduce the amount of moisture. If condensation is still present it is recommended to contact a professional who can diagnose the problem and repair or replace the windows if needed.

It's also important to know that condensation on double-glazed windows could be a sign of a failing seal. The seal that is applied by the factory can wear out over time and allow cool air to pass between the panes. This could cause the window to fog up and eventually develop mold if it is not addressed promptly.

As a quick fix to condensation, try using a hairdryer to dry up the excess moisture. However, this is only temporary solution and should be used as an option last resort. If you let the condensation sit for too long, it could cause dampness or mould in your home. This issue should be dealt with by a professional.

Professionals can reseal double-glazed windows for a more permanent solution. They'll remove the damaged glass pane and clean the gap. They will then pipe hot air into the gap to evaporate any moisture. In this process, they'll also examine for any the presence of mildew, mold or damage growth and apply a draught-proofing process to ensure your windows are fully efficient and energy efficient again.

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 is a simple fix to replace the gaskets that will form an airtight seal. This will keep warm air inside your home, and colder air outside. You will save money on your energy bill.

Misted double glazing indicates that the seals inside your sealed unit (sometimes called a DGU) have been blown. The unit is made up of two panes of glass separated by a spacer bar to create an insulating gap. Then, it is filled with gas, such as argon to make the window airtight. If the seal has blown the water vapour will get into your space through the gap. This can result in condensation between the glass panes which is not able to be removed.

Fortunately it is a simple issue to fix and the windows can be replaced very quickly by experts who have the appropriate tools and know how to do it correctly. The professional will employ a tool designed to push the new seals into place and is generally faster than doing it manually. The tools also have a pointed tip which can be useful for pushing the seals into the corners.

In certain situations an expert could be able to "reseal' your windows by drilling a small hole into the window and then putting in an adsorbent material or putty. This could be a more cost-effective solution than replacements, and will offer a reliable protection against draughts for double glazing.

Faulty Hinges

Many people have encountered misted double-glazing. It could be caused by a broken seal, or a crack in the glass or an issue with the frame or mechanism. It is often possible to fix this problem. Typically, this is done by creating an entirely new seal between the two glass panes. The new seal will stop condensation, draughts and leaks from occurring.

Contact the company from which you bought your windows and tell them of any issues immediately you notice them. You should inform the company in writing and demand 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.

In some instances the window repair expert will cut the hole in your windows to draw moisture out and create an entirely new seal. However, this is usually only a temporary fix and won't stop moisture from returning. Alternatively, it may be possible to replace the glass unit itself which will ensure that it is watertight.

Remember that you should only attempt DIY fixes only if your skills and experience are adequate. Utilizing super glue or any other kind of DIY solution can cause more harm in the long in the long run. If you aren't sure what to do, it's always advisable to seek out professional advice.

Broken Seals

Double glazed windows are secured by seals on windows or gas. They can be damaged by various factors, including weather conditions, age and power washing. It is essential to know the symptoms and how to repair them.

If a window seal fails humid air can leak between the two panes glass, creating fog. This is a common problem that can make the window appear to be distorted. When the seal is damaged, argon and other inert gases are removed from the window, further reducing the glass's insulating qualities.

A damaged window seal can be repaired by replacing it with a new one by a professional glazier. However, this can be expensive and may not solve the fog issue completely. Some companies offer defogging which involves placing a vacuum pump inside the frame of the window to remove moisture and make the glass clear. However this method isn't foolproof and does not replace any inert gases, meaning that the fog may return.

If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is typically the most cost-effective option and is a great option in the event you're looking for the long-term solution. However, it's best to choose a company that has a warranty on replacement windows to ensure that any issues are covered. This way, you can rest sure that you'll get most out of your investment. You can also try to get rid of the issue by choosing the best quality product and following the care guidelines given by the manufacturer. This will prolong the life of the window and cut down the amount of repairs.
