Why Double Glazed Windows Repairs Is More Difficult Than You Think Double Glazed Windows Repairs

There are a variety of reasons your double glazed windows might require repair such as condensation between panes, to drop or sagged frames. Fortunately, a majority of these issues can be resolved.

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

Broken Panes

If a window pane breaks, it loses its insulating properties and can create draft. If the muntins that separate the glass panes also broken, moisture can leak between them causing condensation or mildew, or mould. This can make your home less energy-efficient. It is recommended to have a professional repair the damaged window in order to get the most effective seal and energy efficiency.


The first step is to remove any broken glass. Begin by placing a protective drop cloth beneath the broken window and then cutting around the edges of the pane using an inexpensive glass cutter (available at most hardware stores). It's worth lubricating this tool's cutter with light oil prior to when you begin. This will stop the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the pieces. They should fall off fairly quickly.

After the glass has been removed, scrape away any glazing compound that is old from the recess 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 points can be reused if they're still in good condition.

You'll need to prepare the surface of the remaining frame for reglazing. 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 a cartridge. It should dry before reinstalling the glass. Install the metal clips if they are on the frame. Install the dividers.

Condensation

Condensation is a frequent issue that double-glazed windows face, especially in the winter months. It's typically caused by excessive moisture in the house, with warm air meeting cold glass. This then condenses into water droplets and collects in the corners of your windows or across the frame. This can be prevented by opening windows more frequently, improving ventilation through extractor fans, and using dehumidifiers to reduce moisture levels. If condensation continues to occur you should contact a professional who can diagnose the issue and fix or replace the windows if required.

Condensation on a double-glazed glass window is a sign the seal has failed. The vacuum seal applied at the factory could wear away over time and let cool air get between the panes. This can cause the window to get smudged and eventually develop mold if it's not addressed immediately.

As a quick fix to condensation, try using hair dryers to eliminate the excess moisture. However, this is only a short-term solution and should be used as the last option. If you let the condensation sit for too long, it may lead to mould or dampness within your home. This issue should be dealt with by an expert.

As a long-term solution, you can have your double-glazed windows repaired by professionals. They'll remove the affected piece of glass, then clean the gap and pipe in hot air to evaporate any lingering moisture. During the process, they will also inspect for any damages, mildew or mould growth and apply a draught proofing treatment to ensure that your windows are fully functional and energy efficient.

Draughts

As time goes by the rubber seals around the edges of your glass are likely to break down and this can create a draught in space between the two panes. This is usually a minor problem that can be fixed by re-installing the gaskets and this will create a strong and airtight seal once again. This will keep warm air inside your home, and cooler air out. You will reduce your energy bill.

Double glazing that has mist could be a sign of blow-blown seals. The unit is comprised of two panes of glass 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 which can't be removed.

Fortunately it is a simple problem to fix and the windows can be replaced quickly by experts with the right tools and know how to do it right. The expert will employ tools designed to push the new seals into place and this is normally quicker than doing it manually. These tools also come with a pointed end that can be helpful for pushing the seals into the corners.

In certain cases professionals may 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 less expensive option than replacing your double-glazed windows and still provides you with a Draught-proofing system.

Faulty Hinges

Many people have encountered misted double-glazing. It could be caused by cracked or broken glass or frame or even a damaged seal. The good thing is that this is often solved. Usually, this means creating a new seal between the two panes of glass. The new seal will prevent leaks, condensation and draughts from occurring.

Contact the company from whom you purchased your windows, and let them know of any problems immediately you notice them. Make sure to put this in writing and ask them to confirm that they have received your message. Making sure that everything is in writing will help later on should any disputes arise, as it will be easier to prove that you did indeed complain.

A window repair specialist could drill a hole between your windows to eliminate moisture and make the seal. This is only temporary and won't stop moisture from resurfacing. In addition, it might be possible to replace the glass unit, to ensure that it is watertight.

It is important to remember that you should only try DIY fixes if you have the skills and know-how required to make the attempt. Super glue or other DIY solutions could cause more permanent damage. If you are unsure of what to do, it's always better to seek professional advice.

Broken Seals

Double glazed windows are secured by window seals or insulation gas. They are susceptible to damage due to many factors, such as weather conditions, age, and power washing. It is important to recognize the signs and how to fix them.

When a window seal breaks it allows humidity to seep in between the two glass panes and create fog. It's a frequent issue and it can cause the window to look visually distorted. If the seal fails, the inert gases argon and others are lost from the window, thereby decreasing the glass's insulation properties.

A professional glazier can replace a broken window seal with a brand new one. However, this could be expensive and may not solve the fog issue completely. Certain companies offer defogging solutions that involve putting an air pump inside the window frame to eliminate the moisture and make the glass clear. However, this method is not 100% reliable and cannot replace any inert gas, and the fog can return.

A glazier can also replace the entire IGU (insulated glass unit) in the event that it is beyond repair. This is the most cost-effective option and can be a great choice if you are looking for a long term solution. It is best to choose an organization that offers a warranty on replacement windows. This will ensure that any issues you may have are covered. You can be certain that your investment will provide the most effective results. You can also try to avoid the problem by selecting an item of high-quality and following the care instructions given by the manufacturer. This will extend the lifespan of your window and minimize the need for repairs.
