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 sagging. Many of these issues are fixable.

If your door repair or window is difficult to open, consider oiling the mechanism, hinges and handles. This is usually a cheap, short-term fix.

Broken Panes

If a window pane breaks, it loses its insulation properties and may cause draft. If the muntins that divide the glass panes are also broken, moisture can get in between them and cause condensation, mould or mildew. This will make your home less energy efficient. It is best to have a professional repair a broken window to ensure the best seal and energy efficiency.

Firstly, you'll need to take the broken glass off. 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 a good idea to grease the cutter with lightweight oil before you begin. This will prevent the glass from breaking too easily. Then, you can utilize the tool's ball-shaped end to loosen the pieces and the glass should break away quickly.

Once the glass is removed, scrape any old glazing compound from the recess of the frame. This will reveal the glazier's facets and metal clips that hold the pane in the frame. If there's any indication of corrosion, the clips must be replaced with new ones. If the window is made of wood, the glazier points can be reused if still intact.

You'll then need to prepare the surface of the remaining frame for re-glazing. Using a caulking gun, apply a continuous strip of compound around the inner edge of the recess. Use a high-quality putty such as a glazier’s compound in a cartridge. Allow it to dry prior to re-inserting the glass. Install the metal clips if they are on the frame. Finally, reinstall the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, especially in winter. It's typically caused by too much moisture in the house as warm air meets cold glass, which forms into water droplets and then collects in the corners of your windows or across the frame. It can be prevented by opening windows more regularly and enhancing ventilation with extractor fans and running dehumidifiers to reduce moisture levels. If condensation continues to occur it is recommended to contact an expert who can identify the problem and repair or replace the windows if needed.

It's also important to note that condensation on windows with double glazing could be a sign of a failing seal. This is due to the vacuum seal that was applied by the manufacturer can be damaged over time, allowing cool air to flow between the panes. This could cause the window to fog up and eventually develop mold if it's not addressed promptly.

As a quick fix for condensation, you can try using a hairdryer to dry up the excess moisture. This is a temporary solution and should be used only as a last alternative. If the condensation is left for a long time it may be experiencing mould or dampness in your home, which needs to be addressed by a professional.

Professionals can reseal your double-glazed window to provide a longer-lasting solution. They'll take off the affected glass pane and clean the gap. They will then pipe hot air into the gap to eliminate any moisture. During this process, they'll examine for any damage, mildew or mould growth and carry out an draught-proofing procedure to ensure that your windows are fully efficient and energy efficient again.

Draughts

Rubber seals can wear down over time and cause a draft between your two panes. This is often a simple issue that can be resolved by re-installing the gaskets and this will create a strong and airtight seal once again. This will keep warm air in your home, and the colder air out, thereby saving you money on your energy bills.

Misted double glazing is a sign the seals inside your sealed unit (sometimes called a DGU) have blown. The unit is comprised of two glass panes filled with argon separated by a spacer to create an airtight window. If the seal has been blown it allows water vapour to enter your room through the gap, creating condensation between the panes that is not able to be cleaned off.

This is a simple issue to fix, and windows can be swiftly replaced by experts using the right tools. The specialist will use an instrument designed to push the new seals in place and this is normally quicker than trying to do it by hand. The tools have an edge that can be used to push seals into corners.

A professional may be able'reseal your windows by drilling a small gap in the window, and adding a desiccant or putty. This could be more cost-effective than replacements and will provide a reliable draught-proofing system for double glazing.

Faulty Hinges

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

If you spot any issues, you must contact the company that sold you the windows. It is important to notify the company in writing and ask for confirmation that they received your notification. Writing everything down will help later on should any disputes arise, because it will be easier to prove that you actually complained.

Broken Seals

Window seals, also known as insulation gas fills, are what hold double glazed windows in place. A variety of factors can cause them to break, such as weather conditions, age and power washing. It's crucial to be aware of what the signs are and how to repair them.

When a window seal fails it allows humidity to seep in between the two glass panes and create fog. This is a common problem that can also make the window appear to be distorted. If the seal fails, gas like argon as well as other inert gases are removed from the window, further diminishing the glass's insulation capabilities.

A broken window seal can be fixed by replacing it with a new one by an experienced glazier. This is costly and may not solve the fog issue. Some companies offer defogging which involves placing an air pump inside the window frame to eliminate moisture and clear the glass. This method is not foolproof and does not replace the inert gasses, so the fog could return.

If the IGU (insulated unit) is beyond repair, a glazier may replace it. This is the most cost-effective solution and is a great option if you're seeking a long-term solution. It's best to select a company who offers a warranty on replacement windows. This will ensure that any problems you might face are covered. You can be assured that your investment will yield the most effective 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 lifespan of the window and cut down the number of repairs.
