Double Glazed Windows Repairs

Double-glazed windows require repair for a variety of reasons, like condensation between the panes, draughts, or frames that are sagging. Most of these problems are fixable.

Try applying lubrication to the hinges, handles, and mechanisms of your door or window doctor in case it is hard to open. This is a quick, affordable solution.

Broken Panes

When a window pane breaks it loses its insulating properties and may cause draft. If the dividing muntins are also damaged, it could cause moisture to leak between the glass panes, resulting in condensation, mildew and mould and making your home less efficient in energy use. A window that is damaged should be repaired by an expert to ensure you get a perfect seal and maximum energy efficiency.

In the beginning, you'll have to take the broken glass off. Start by placing a low-cost glass cutter from a hardware store under the broken pane. It's recommended to lubricate the cutter with a light oil before you begin. This will stop the glass from breaking too easily. You can then utilize the tool's ball-shaped end to loosen the fragments and they should fall away quickly.

Scrape any old glazing compound off the recess of the frame once the glass has been removed. This will expose the glazier's point and metal clips that keep the pane in the frame. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is made of wood, the glazier points can be reused if they are still in good shape.

The remaining frame needs to be prepared to allow re-glazing. Apply a continuous strip of compound to the recess using a caulking tool. Use a high-quality putty, such as a glazier’s compound in cartridge. Dry it out before reinstalling the glass. Reinstall the metal clips if they are attached to the frame. Then, you can reinstall the divider muntins.

Condensation

Condensation is a frequent issue that double-glazed windows face particularly in winter months. It's usually caused by high moisture levels within your home. Warm air is absorbed by cold glass and condenses to droplets of water. They then settle in the corners or frames of the window. This can be avoided by opening windows more regularly, 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 an expert to determine the bottom of the issue. You can then fix or replace your windows when necessary.

It's also important to note that condensation on double-glazed windows can be an indication of a failing seal. The vacuum seal applied at the factory can wear out over time and allow cool air to get between the panes. This could cause the window to get smudged and then develop mold if not addressed immediately.

As a quick fix to condensation, you can try using hair dryers to eliminate the excess moisture. This is only a temporary solution and should be used only as a last option. If you leave the condensation for too long, it could lead to mould or dampness within your home. This issue should be dealt with by a professional.

Professionals can seal your double-glazed window for a better, more durable solution. They'll remove the affected pane of glass, clean out the gaps and pipe into hot air to eliminate any lingering moisture. During the process, they'll also check for any damages or growth of mould, mildew or mildew and then perform an draught-proofing procedure to ensure that your windows are efficient and energy efficient once more.

Draughts

Rubber seals can wear out over time and cause drafts between your two panes. It is simple to replace the gaskets, which will create an airtight seal. This will keep warm air inside your home and cooler air outside. You can save money on your energy bill.

Misted double glazing indicates that the seals inside the sealed unit (sometimes called a DGU) have blown. The unit is made up of two panes of glass separated by an insulating bar that creates an insulating space. It is then filled with gas, like argon to make the window airtight. If the seal has been blown, water vapour will enter your home through the gap. This can cause condensation between the glass panes, which can't be sucked out.

This is a straightforward issue to solve and windows can be swiftly replaced by specialists with the right tools. The specialist will use a tool designed to push the new seals in place and is generally faster than doing it by hand. These tools feature an edge that can be used to push the seals into corners.

A professional may be able'reseal your windows by drilling a small opening in the window, and then adding a desiccant or putty. This is more cost-effective than replacements and it will still give you an effective draught-proofing system for your double-glazed windows.

Faulty Hinges

Misted double glazing is a frequent problem that many people experience. It can be caused by cracked or broken glass or frame or even a broken seal. It is possible to fix this problem. This typically involves creating a seal between the two glass panes. The new seal will prevent condensation, draughts, and leaks from happening.

If you discover any issues, you should contact the company that sold you your windows. Be sure to do this in writing and request them to confirm that they have received your notice. Making sure that everything is in writing will make it easier to resolve any disputes arise, because it will be 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 remove moisture and form an airtight seal. However, this is generally only a temporary solution and will not stop the moisture from returning. It may also be possible to replace just the glass part, which will make it watertight.

Be aware that you should only attempt DIY fixes if your skills and knowledge are adequate. Super glue or other DIY solutions could cause more permanent 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 a variety of elements, including weather conditions, age and power washing. It is essential to be aware of the signs and the best way to fix them.

When a window seal fails, humid air can seep between the two panes glass, causing fog. It's a common problem, and it can also cause the window to appear visually altered. Once the seal fails it is when any argon or other inert gas is lost from the glass, further diminishing its insulating properties.

A damaged window seal can be repaired by replacing it with a the new one by an experienced glazier. This can be expensive and may not completely solve the fog issue. Certain companies offer defogging solutions which include putting an air pump inside the window frame to eliminate the moisture and make the glass clear. This method isn't foolproof and doesn't replace inert gasses, so the fog may come back.

If the IGU (insulated unit) is beyond repair, a glazier could replace it. This is usually the most cost-effective solution and could be a good option if you're seeking an option that lasts for a long time. But, it's best to choose a company that has a warranty on replacement windows to ensure that any problems are protected. This way, you can rest at ease knowing that you'll get maximum value for your investment. You can also try to avoid this issue by choosing a high-quality window and following the manufacturer's maintenance instructions. This will prolong the lifespan of the window and reduce the number of repairs.
