What Experts In The Field Of Double Glazed Windows Repairs Want You To Know
Double Glazed Windows Repairs
Double-glazed windows require repair for a variety of reasons including condensation between the panes, draughts, or frames that are sagging. Thankfully, most of problems can be addressed.
Try to lubricate the hinges, handles and mechanisms of your door or window in case it is hard to open. This is usually a low-cost, short-term fix.
Broken Panes
If a window pane breaks, it loses its insulation properties and could cause draft. If the dividing muntins also damaged, it could cause water to leak through the glass panes, resulting in condensation, mold and mildew and making your home less energy efficient. A window that is damaged should be repaired by an expert to ensure you get the correct seal and maximum energy efficiency.
In the beginning, you'll have to remove the broken glass. Begin by placing a cheap glass cutter from an hardware store underneath the broken pane. Before you start, make sure to lubricate the cutter of this tool using an oil that is light. This will stop the glass from breaking too easily. You can then use the tool's ball-shaped end to loosen the pieces and they should fall off fairly quickly.
Once the glass is removed, scrape any old glazing compound from the recess of the frame. This will expose the metal clips and glazier's pins that keep the glass in place. Replace them if there is any corrosion. If the window is made of wood the glazier points can be reused if they're still in good shape.
You'll then need to prepare the surface of the frame to be re-glazed. With 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 compound that is contained in cartridge. Let it dry before inserting the glass. If the frame has metal clippings, they should be replaced as well. Then, you can reinstall the divider muntins.
Condensation
Condensation is one of the most common issues that double-glazed windows can experience, especially in the winter months. It's typically caused by excessive humidity in the home, with warm air meeting cold glass, which then condenses into water droplets and collects in the corners of your windows or across the frame. This can be avoided by opening windows more regularly and enhancing ventilation with extractor fans and running dehumidifiers to lower the moisture levels. If condensation is still an issue, it's crucial to get an expert to determine the bottom of the issue and fix or replace your windows as necessary.
Condensation on a double-glazed window is a sign the seal has failed. This is because the factory-applied vacuum seal may be damaged in time, allowing cool air to make its way between the panes. This can cause the window to become cloudy and eventually develop mold if not addressed quickly.
As a quick fix to condensation, you could try using hair dryers to eliminate the excess moisture. However, this is just a short-term solution and should only be used as the last resort. If you leave the condensation for too long, it could cause dampness or mould within your home. This issue should be dealt with by a professional.
As a longer-term solution, you can have your double-glazed windows resealed by professionals. They will remove the affected glass pane and clean the gap. They will then pipe hot air into the area to evaporate any moisture. During the process, they'll check for damage, mould or mildew growth, and then apply a draught-proofing process to ensure your windows are fully operational and energy efficient again.
Draughts
Rubber seals can get worn out over time and cause drafts between your two panes. It's simple to replace the gaskets, that will form an airtight seal. This will allow warm air inside your home, and the colder air out, thereby saving you money on your energy bills.
Misted double glazing is a sign the seals in your sealed unit (sometimes called a DGU) have been blown. The unit is comprised of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal has been blown the water vapour will get into your space through the gap. This can cause condensation between the glass panes which can't be sucked out.
Fortunately it is a simple problem to fix, and windows can be replaced quickly by experts who have the appropriate tools and know how to do it properly. The specialist will use a tool designed to push the new seals into position and is generally faster than trying to do it by hand. These tools have a pointed tip that can be used to push seals into corners.
A professional might be able to reseal your windows' by drilling a small opening into the window, and then adding a desiccant or putty. This could be more cost-effective than replacements and will provide a reliable draught-proofing system for your double-glazed windows.
Faulty Hinges
Misted double glazing is a common issue that many people face. This can be caused by a broken or cracked glass frame or even a broken seal. The good news is that this can often be fixed. Usually, this means creating an entirely new seal between the two panes of glass. The new seal will stop condensation, draughts, as well as leaks.

Having everything in written form will make it easier to resolve any disputes arise, since it is easier to prove that you actually complained.
In certain situations an expert in window repair will drill the gap in your windows to draw out moisture and create the new seal. However, this is typically only a temporary fix and will not stop moisture from returning. It might also be possible to replace the glass part, which will make it watertight.

Broken Seals
Double-glazed windows are secured by window seals or insulation gas. There are a variety of reasons that can cause them to break, like the weather, age, and power washing, so it's essential to be aware of what symptoms are and how to repair them.
When a window seal fails humid air can get between the two panes of glass, causing fog. This is a common issue, and it can also cause the upvc window repairs to appear visually distorted. Once the seal fails it is when any argon or other inert gas is lost from the glass, further decreasing its insulation properties.
A broken window seal can be fixed by replacing it with a a new one by an experienced glazier. This can be expensive and may not solve the fog issue. Some companies offer defogging, which involves putting an air pump inside the window frame in order to eliminate moisture and clear the glass. This method isn't 100% reliable, and it doesn't replace inert gasses, so the fog may come back.
A glazier can also replace the entire IGU (insulated glass unit) in the event that it is beyond repair. This is usually the most cost-effective solution and can be a good choice in the event you're seeking the long-term solution. But, it's best to choose a company that offers a warranty for replacement windows to ensure that any issues are protected. You can be certain that your investment will yield the best results. You can also try to avoid this issue by choosing an item of high-quality and following the care guidelines given by the manufacturer. This will prolong the lifespan of your window and minimize the need for repairs.
