Double Glazed Windows Repairs

Double-glazed windows require repair for a variety of reasons including condensation between the panes, draughts, or frames that are sliding. Thankfully, most of these issues can be fixed.

If your door or window is difficult to open, try oiling the hinges, mechanism and handles. This is a simple, inexpensive fix.

Broken Panes

When a window pane breaks it loses its insulating properties and can create draft. If the dividing muntins are also broken, it could cause moisture to leak between the glass panes, resulting in condensation, mold and mildew and making your home less energy efficient. A broken window is best repaired by an expert to ensure that you get a perfect seal and optimum energy efficiency.

First, you'll need to take out any broken glass. Begin by placing a cheap glass cutter in an appliance store beneath the broken pane. It's recommended to lubricate the cutter with a light oil before you begin. This will help prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to break the pieces. They should come off quite quickly.

Scrape any old glazing compound off the recess of the frame after the glass has been removed. This will reveal the glazier's facets and metal clips that hold the pane in place. Replace them if there's any corrosion. If the window is made of wood the glazier points can be reused if they are still in good condition.

The surface of the remaining frame needs to be prepared for re-glazing. Apply a continuous strip of compound to the recess using the caulking tool. Make use of a premium putty, such as glazier’s compound in cartridge. Let it dry before installing the glass. Install the metal clips if they are on the frame. Then, you can reinstall the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, especially during the winter. This is usually caused by too many levels of moisture in your home. Warm air meets cold glass, which condenses into water droplets. These then collect in the corners and frame of the window. You can stop this from happening by opening your windows more often, improving ventilation with extractor fans, and utilizing dehumidifiers. If condensation remains an issue, it's best to contact an expert to get to the bottom of the issue and fix or replace your windows if necessary.

It's also important to know that condensation on windows with double glazing could be a sign of a failing seal. This is because the factory-applied vacuum seal may break down in time and allow cool air to move between the panes. This can cause the window to get smudged and eventually develop mold if it's not addressed quickly.

For a quick fix to condensation, you can try using hair dryers to dry the excess moisture. However, this is only temporary solution and should be only used as a last resort. If the condensation has been allowed to sit for too long, you may be experiencing mould or dampness in your home, which needs to be dealt with by a professional.

Professionals can reseal your double-glazed window to provide a longer-lasting solution. They will remove the affected glass pane and clean the gap. They will then pipe hot air into the gap to eliminate any moisture. In this process, they'll look for signs of damage, mildew or mould growth, and then apply a draught-proofing process to ensure that your windows are fully efficient and energy efficient again.

Draughts

As time goes by the rubber seals around the edges of your glass are likely to break down and this can cause a draught to form in the space between the two panes. It's simple to replace the gaskets which will result in an airtight seal. This will allow warm air in your home and the colder air outside, saving you money on your energy bills.

Double glazing that is misted could be a sign of sealed blown seals. The unit is comprised of two panes of glass filled with argon separated by a spacer, creating an airtight window. If the seal is blown it will allow water vapour to get into your space through the gap, which will cause condensation between the panes that can't be removed.

This is a straightforward issue to repair, and windows can be quickly replaced by specialists with the right tools. The expert will employ an instrument designed to push the new seals into place and is generally faster than doing it by hand. These tools feature an edge that can be used to push seals into corners.

In certain cases, a professional may be able to 'reseal' your windows by drilling a small hole into the window and adding the desiccant material, or putty. This is a less expensive option than replacing your double-glazed windows and still provides you with an effective draught proofing system.

Faulty Hinges

Misted double glazing is a typical issue that many people face. It may be caused by a damaged seal or a crack in the glass, or an issue with the frame or mechanism. The good thing is that this can often be fixed. Typically, this is done by making an entirely new seal between the two panes of glass. The new seal will prevent leaks, condensation and draughts from occurring.

Contact the company through which you purchased your windows, and inform them of any problems immediately you discover them. It is important to notify the company in writing and request confirmation that they received your notification. If there are any disputes being resolved, writing everything down will help you prove your complaint.

In certain situations the window repair expert will cut the hole in your windows to draw out moisture and make an entirely new seal. This is a temporary fix that will not stop the return of moisture. Alternatively, it may be possible to replace the glass unit itself which will ensure it is watertight.

It is important to remember that you should only try DIY fixes only if you have the experience and knowledge necessary to make the attempt. Super glue or other DIY solutions can cause more permanent damage. If you are unsure of what to do, it is always recommended to seek professional advice.

Broken Seals

double glazed window repairs glazed windows are held in place by window seals or insulation gas. They can be damaged by various factors, including weather conditions, age, and power washing. It is crucial to recognize the signs and how to repair them.

If a window seal is damaged it allows humidity to seep in between the two glass panes and create fog. It's a common problem, and it can cause the window to appear visually disoriented. Once the seal fails the argon or any other inert gas is removed from the glass, decreasing its insulation properties.

A professional Glazier can replace a damaged window seal with a brand new one. However, this can be expensive and may not solve the fog problem entirely. Some companies offer defogging services that involve putting an air pump inside the window frame to eliminate the moisture, leaving the glass clean. 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 could replace it. This is usually the most cost-effective solution and can be a good choice in the event you're seeking an option that lasts for a long time. It is recommended to choose a firm that offers a warranty for replacement windows to ensure that any problems are covered. You can be sure that your investment will yield the best results.
