Double Glazed Windows Repairs

There are many reasons your double glazed windows might require repair such as condensation between panes, to dropping or sagging frames. Fortunately, the majority of problems can be addressed.

If your window or door is difficult to open, consider oiling the hinges, the mechanism and handles. This is a quick and affordable solution.

Broken Panes

When a window pane is broken, it loses its insulation properties and can create a draft. If the dividing muntins are broken it can cause water to leak between the glass panes resulting in condensation, mildew and mould and making your home less energy efficient. A damaged window should be repaired by an expert to ensure that you get the correct seal and optimum energy efficiency.

The first step is to take out any broken glass. Begin 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). Before you start, make sure to lubricate the cutter with an oil that is light. This will stop the glass from breaking too easily. Then, you can use the tool's ball-shaped end to loosen the pieces and the glass should break away fairly quickly.

Once the glass is removed, scrape off any old glazing compound that has accumulated in the recess area of the frame. This will expose the glazier's point and metal clips that keep the pane in the frame. Replace them if there's any corrosion. If the window is made of wood the glazier's points could be used again if they're in good condition.

The next step is to prepare the surface of the remaining frame for reglazing. Apply a continuous strip compound to the recess with the caulking tool. Use a high-quality putty, such as a Glazier's compound in a cartridge. Dry it out before installing the glass. Reinstall the metal clips if they are attached to the frame. Finally, put back the divider muntins.

Condensation

Condensation is one of the most common issues that double-glazed windows can experience particularly in wintertime. It's typically caused by too much moisture in the house, with warm air meeting cold glass. This then turns into water droplets, and collects in the corners of your windows or across the frame. This can be avoided by opening windows more frequently, improving ventilation through extractor fans and running dehumidifiers to lower the moisture levels. If condensation remains a problem, it's important to contact an expert to get to the root of the issue and fix or replace your windows when needed.

It's also important to remember that condensation on double-glazed windows can actually be an indication of a leaky seal. The seals that are applied at the factory could wear away 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.

Hairdryers can be used to eliminate excess moisture. However, this is just temporary solution and should only be used as a last resort. If the condensation is left for too long, you could be looking at 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 resealed by professionals. They'll remove the affected pane of glass, then clean the gaps and pipe in hot air to evaporate any lingering moisture. During the process, they will also look for any signs of damage or growth of mould, mildew or mildew and apply a draught proofing treatment to ensure that your windows are functional and energy efficient.

Draughts

As time passes, the rubber seals around the edges of your glass insulated can break down and this can create a draught in space between the two panes. It is a simple fix to replace the gaskets which will create an airtight seal. This will keep warm air inside your home and colder air outside. You will reduce your energy bills.

Misted double glazing is a sign the seals of your sealed unit (sometimes called a DGU) have blown. The unit consists of 2 panes of glass separated by the spacer bar to create an insulating gap. Then, it is filled with gas, such as argon for example, to make the window repairs (visit website) airtight. If the seal has blown it will allow water vapour to enter your room through the gap, which will cause condensation between the panes that is not able to be cleaned off.

Fortunately it is a simple issue to fix and the windows can be replaced quickly by experts who have all the right tools and know how to do it properly. The professional will employ an instrument that is designed to push into the new seals. This is typically faster than doing it manually. The tools also have a pointed tip which is useful to push the seals into the corners.

In certain cases, a professional may be able to 'reseal' your windows by drilling a small hole in the window and adding the desiccant material, or putty. This is a cheaper solution than replacing your double-glazed windows and will still provide you with an effective air-tight system for draughtproofing.

Faulty Hinges

Many people have experienced misted double glazing. It could be caused by a broken seal, or a crack in the glass, or a problem with the mechanism or frame. The good news is that this can be easily repaired. This typically involves creating a seal between the two glass panes. The new seal will prevent condensation, draughts, as well as leaks.

If you spot any issues, you must contact the company that sold you your windows. Make sure you do this in writing and request them to confirm that they have received your notice. Having everything in written form will make it easier to resolve any disputes arise, as it will be easier to prove that you actually complained.

In some instances the window repair expert will drill the gap in your windows to draw out moisture and make a new seal. However, this is usually only a temporary solution and won't stop moisture from returning. In addition, it might be possible to replace the glass unit itself, to ensure that it is watertight.

Broken Seals

Window seals, also known as gas fills, keep double glazed windows in place. They are susceptible to damage due to various elements, including weather conditions, window repairs age and power washing. It is crucial to know the symptoms and the best way to fix them.

When a window seal breaks it allows humidity to get into the two glass panes and create fog. It's a frequent issue and it can cause the window to appear visually altered. Once the seal fails, argon and other inert gases are lost from the window, diminishing the glass's insulation capabilities.

A damaged window seal can be fixed by replacing it with an entirely new one by an experienced glazier. This can be expensive and might not be able to resolve the fog issue. Some companies offer defogging services that involve putting the vacuum pump of a specific type inside the window frame to eliminate the moisture, leaving the glass clear. However, this method is not foolproof and doesn't replace any inert gas, and the fog could come back.

A glazier can also replace the entire IGU (insulated glass unit) when it's beyond repair. This is the most cost-effective option and is a great choice if you are looking for a long-term solution. It's best to select a company who offers warranties on replacement windows. This guarantees that any issues you might face are covered.
