Double Glazed Windows Repairs

Double glazed windows can need repair for many reasons, including condensation between the panes, draughts, or frames that are sagging. Many of these issues can be solved.

Try applying lubrication to the hinges, handles, and mechanisms of your window or door when it is difficult to open. This is a quick, cheap solution.

Broken Panes

If a window pane breaks, it loses its insulating properties and could cause draft. If the muntins that separate the glass panes are broken, water can get in between them and cause condensation, mould or mildew. This can make your home less energy efficient. A broken window is best repaired by an expert to ensure you get a perfect seal and the optimum energy efficiency.

First, you'll need to remove the broken glass. Begin by placing a protective drop cloth under 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 stop the glass from shattering too easily. Then, you can make use of the tool's ball-shaped tip to loosen the pieces and the glass should break away fairly quickly.

Scrape any old glazing compound out of the frame's recess after the glass is removed. This will expose the metal clips and glazier's pins that keep the glass in the frame. If there's any sign of corrosion, these should be replaced with new ones. If the window is made of wood, the glazier's points can be reused if they're intact.

You'll need to prepare the surface of the frame for reglazing. With a caulking gun apply a continuous strip of compound around the inside edge of the recess. Use a high-quality putty, such as Glazier's compound that is contained in cartridge. It should dry before reinstalling the glass. Reinstall the metal clips, if they are attached to the frame. Reinstall the divider muntins.

Condensation

Condensation can cause problems for double-glazed windows, particularly during winter. It's typically caused by too much moisture in the house, with warm air meeting cold glass, which turns into water droplets, and settles in the corners of your windows or double glazing across the frame. It can be prevented by opening windows more frequently and enhancing ventilation with extractor fans and running dehumidifiers in order to reduce the amount of moisture. If condensation continues to occur, you should call an expert who can identify the issue and fix or replace the windows if required.

It's also important to remember that condensation on windows with double glazing could be a sign of a leaky seal. The vacuum seal applied at the factory could wear away over time and allow cool air to pass between the panes. This could cause the window to become cloudy and eventually grow mold if it's not addressed immediately.

You can use a hairdryer as a quick solution to eliminate excess moisture. This is a temporary fix and Double glazing should only be used as a final alternative. If the condensation is left for a long time you may be experiencing mould or dampness in your home, which should be dealt with by a professional.

As a longer-term solution, you can get your double-glazed windows sealed by professionals. They'll remove the affected pane of glass, clean out the gaps and pipe in hot air to evaporate any lingering moisture. During the process, they will also check for any damages, mildew or mould growth and then perform a draught proofing treatment to ensure that your windows are fully efficient and energy efficient once more.

Draughts

The rubber seals wear out over time and create drafts between your two panes. This is often a simple issue that can be resolved by re-installing the gaskets and this will result in a sturdy and airtight seal. This will keep warm air inside your home and colder air outside. You can save money on your energy bill.

Misted double glazing is a sign the seals inside the sealed unit (sometimes called a DGU) have been blown. The unit is comprised of two panes of glass separated by an insulating bar that creates an insulating gap. Then, it is filled with gas, such as argon for example, to make the window airtight. If the seal has blown it will allow water vapour to get into your space through the gap, which will cause condensation between the panes which can't be removed.

This is a simple problem to solve and windows can be swiftly replaced by experts using the appropriate tools. The professional will employ an instrument designed to push the new seals into place and this is normally quicker than attempting to do it manually. The tools have a pointed tip that can be used to push seals into corners.

In some cases, a professional could be able to "reseal your windows' by drilling a small opening into the window and then putting in an adsorbent material or putty. This is a more cost-effective solution than replacements and it will still give you an effective draught-proofing solution for your double glazing.

Faulty Hinges

Misted double glazing is a common problem that many people experience. It may be caused by a damaged seal or a crack in the glass, or a problem with the mechanism or frame. It is possible to fix this problem. Normally, this involves creating a new seal between two glass panes. The new seal will help prevent condensation, draughts and leaks.

If you discover any problems, you should contact the company that sold you the windows. You should inform the company in writing and demand confirmation that they received your message. Having everything in written form will be helpful later if any disputes arise, as it is easier to prove that you actually complained.

A window repair expert might be able to drill a hole in the gap between your windows to remove moisture and make a seal. However, this is generally only a temporary fix and won't stop the return of moisture. It is also possible to replace the glass unit, which will ensure it is watertight.

Be aware that you should only attempt DIY fixes with the knowledge and skills you have are adequate. Utilizing super glue or any other kind of DIY solution can cause more harm in the long run.

Broken Seals

Double glazed windows are secured by seals on windows or gas. They can be damaged by various factors, such as weather conditions, age and power washing. It is essential to be aware of the signs and how to fix them.

When a window seal fails humid air can get between the two panes of glass, causing fog. This is a frequent issue that can also make the window appear disfigured. Once the seal fails the argon or any other inert gas will be removed from the glass, thereby reducing its insulating properties.

A professional Glazier can replace a damaged window replacement seal with a brand new one. However, this can be expensive and may not solve the fog problem entirely. Some companies offer defogging which involves putting an air-pump inside the window frame to eliminate moisture and clear the glass. However this method isn't foolproof and does not replace any inert gas, and the fog could come back.

A glazier may also replace the entire IGU (insulated glass unit) if it is beyond upvc repair. This is the most cost-effective method and is a good option if you're looking for a long-term solution. It is best to choose a company who offers warranties on replacement windows. This will ensure that any issues you may have are covered. You can be certain that your investment will produce the best results. Alternately, you can attempt to avoid this issue by choosing a high-quality window and following the manufacturer's care instructions. This will prolong the life of the window and decrease the amount of repairs.
