double glazing repairs Glazed Windows Repairs

Double-glazed windows may require repair for a variety of reasons including condensation between the panes, draughts or frames that are sagging. Most of these problems can be resolved.

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

Broken Panes

When a window is broken it loses its insulation properties and window repair can cause a draft. If the muntins that separate the glass panes are also damaged, moisture could leak between them causing condensation and mildew, as well as mould. This will make your home less efficient in energy use. It is best to have an expert repair a damaged window in order to get the most effective seal and energy efficiency.

The first step is to take out any broken glass. Begin by putting a 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). Before you start, lubricate the cutter of this tool with a light oil. This will stop the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the fragments. They should come off fairly quickly.

Once the glass is removed, scrape off any old glazing compound that has accumulated in the recess of the frame. This will reveal the glazier's facets and the metal clips that hold the pane in place. If there's any sign of corrosion, these clips should be replaced with new ones. If the window is constructed of wood the glazier points can be reused if they are still intact.

The remaining frame must be prepared for reflazing. Using a caulking gun, apply a continuous strip of compound along the inside edge of the recess. Use a high quality putty, such as a Glazier's compound that is contained in a cartridge. Dry it out before reinstalling the glass. If the frame is made of metal clippings, these should be replaced as well. Then, you can reinstall the divider muntins.

Condensation

Condensation is a concern for double-glazed windows, particularly during the winter. This is usually caused by high levels of moisture in your home. Warm air is absorbed by cold glass, which condenses into droplets of water. These then collect in the corners and frame of the window. You can stop this from happening by opening your windows more frequently, improving ventilation with extractor fans, and using dehumidifiers. If condensation persists it is recommended to contact an expert who will be able to pinpoint the issue and fix or replace the windows if necessary.

Condensation in a double-glazed glass window is a sign the seal has failed. The seals that are applied at the factory can wear out over time and allow cool air to get between the panes. This could cause the window to fog up and then develop mold if not addressed immediately.

A hairdryer can be used as a quick solution to get rid of excess moisture. However, this is only temporary solution and should be only used as a last option. If the condensation has been allowed to sit for too long it might be facing mold or dampness within your home, which needs to be addressed by a specialist.

As a longer-term solution, you can have your double-glazed windows repaired by experts. They will remove the affected glass pane and clean the gap. They will then pipe hot air into the gap to dry out any moisture. In this process, they'll look for signs of damage, mildew or mould growth and apply an draught-proofing procedure to ensure that your windows are fully operational and energy efficient again.

Draughts

Rubber seals can get worn out over time and cause drafts between the two panes. This is usually a minor problem that can be fixed by replacing the gaskets, and this will result in a solid and airtight seal. This will keep warm air inside your home, and cooler air outside. You'll reduce your energy bill.

Misted double glazing is a sign that the seals in your sealed unit (sometimes called a DGU) have blown. The unit is composed of two panes of argon-filled glass separated by a spacer to form an airtight window. If the seal has blown water vapour can enter your space through the gap. This can cause condensation between the glass panes that is not able to be removed.

This is a simple issue to solve, and windows can be easily replaced by experts using the proper tools. The professional will employ an instrument that is designed to push into the new seals. This is typically faster than doing it manually. These tools also come with a pointed end that can be helpful for pushing seals into the corners.

In certain cases, a professional might be able to "reseal' your windows by drilling a small opening into the window and then adding an adsorbent material or putty. This is a cheaper solution than replacing your double glazing and will still provide you with a air-tight system for draughtproofing.

Faulty Hinges

Many people have experienced misted double glazing. It can be caused by a broken seal, or a crack in the glass or an issue with the mechanism or frame. The good news is that it is often solved. Usually, this means creating an entirely new seal between the two panes of glass. The new seal will prevent leaks, condensation and draughts from happening.

If you discover any problems, you should contact the company that sold you the windows. Be sure to do this in writing, and request them to confirm that they've received your notice. If there are any disagreements, having everything in writing will help you prove your claim.

In certain situations an expert in window repair may be able to drill a hole in your windows to draw moisture out and create a new seal. However, this is generally only a temporary solution and will not stop the moisture from returning. It is also possible to replace the glass unit, to ensure that it is watertight.

Remember that you should only try DIY fixes only if your skills and experience are sufficient. Super glue or other DIY solutions can cause more permanent damage.

Broken Seals

Window seals, also known as insulation gas fills, are what hold double-glazed windows in place. They can be damaged by many factors, including weather conditions, age, and power washing. It is crucial to know the symptoms and how to fix them.

When a window seal fails, humid air can seep between the two panes glass, causing fog. This is a frequent issue that can cause 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 damaged window seal can be fixed by replacing it with a a new one by an experienced glazier. This is costly and might not be able to resolve the fog issue. Certain companies offer defogging solutions which include putting an air pump inside the window frame to remove the moisture and make the glass clean. However, this method is not 100% reliable and cannot replace any inert gas, and the fog can return.

If the IGU (insulated unit) is damaged beyond repair, a glazier can replace it. This is usually the most cost-effective option and can be a good choice if you're looking for an option that lasts for a long time. But, it's best to select a company with a guarantee for replacement windows to ensure that any problems are covered. You can be sure that your investment will yield the most effective results. You can also avoid this issue by choosing an item of high-quality and following the maintenance instructions given by the manufacturer. This will help to prolong the life of your window and minimize the need for repairs.
