Can Double Glazed Windows Be Repaired?

If you have recently had double glazing installed in your home and are beginning to show signs of failing you may be wondering if they are able to be repaired.

You may be able get your double glazing covered under warranty, based on the issue and the date when you bought it.

Broken Panes

When a window pane is broken or cracked, air can pass through more easily. This decreases the effectiveness of the window as an insulation barrier and also against the elements. Based on the season it can allow warm or cold air to enter or escape your home, increasing heating and cooling costs.

If the crack is not too deep, you may be able to utilize a strong-hold adhesive tape. This is only a temporary solution however, and could only stop the crack from getting worse. A professional window repair service can fix any broken glass on your double-glazed windows.

It can be dangerous and challenging to replace windows on your own. If the crack is too large to grasp, try pressing strips of masking tape across it in a crisscross pattern before trying to remove it. If the crack is small enough to be able to hold it in place and use a razor to cut it off from the frame. Make sure to wear gloves and a mask when cutting glass. Once the pane is free, you will need to place it flat on several layers of newspaper to catch any pieces that may fall.

To install a replacement glass, you'll need to prepare the frame and buy replacement glass. Take measurements of the opening of the frame and subtract 1/16 - 1/8 inch in both directions to ensure that your new pane is a good fit. Cut your replacement glass at a local hardware or glass shop according to this measurement. If you have wood frames, you can purchase points for glaziers at a hardware store to install along the edges of your new pane. The points should be placed in a manner they can allow for expansion and contraction, while keeping the putty flush against the glass.

Spread a thick layer using a putty blade once your new pane has been installed. Use a linseed-oil-based putty like Sarco or a cheaper product such as Dap glazing compound. Fill any gaps between the frame and the new pane using the compound you choose. Smooth the compound around your new pane to ensure it is level and even.

Water Leaks

Water leaks around a window's frame or sash are a common problem. This happens when the window sealant is worn out and needs to be replaced. Water leaks can cause damage to the drywall and plaster around the window. They can also result in damp or moldy walls that need to be restored as quickly as is possible.

A double-glazed window of high quality will have a gasket which compresses firmly when the sash closes. Water that falls on this area should be drained out through the weepholes in the frame. Sometimes the weep hole can be blocked due to dirt and debris. Also, the weather stripping may need replacing.

The lintel that is above the window can be an area of leaks. The builders who constructed the house might not have understood the importance of allowing the lintel drain properly, or have covered it in concrete, which left a gap in which rainwater could enter and get trapped, creating dampness or rot on the wood. The installers should have placed the fascia boards in a slant above the window to ensure that water is directed properly and this will stop water from entering the building through these gaps.

A gap between the glass panes of a double-glazed window can also be the cause of leaks. A worn seal could have caused the gas argon or krypton which is supposed to be between the glass panes to create insulation to leak out. Although this isn't the most serious issue with leaky windows however, it could affect energy efficiency. It is important to address the issue as quickly as possible. In this instance replacement double glazing might be a good idea. A professional can conduct an extensive evaluation, let you know where the leak is coming from and suggest a solution. They'll also be able to advise whether it is appropriate to repair the window or replace it completely. They will also provide an estimate for any work needed.

Condensation

Condensation may be a problem with older double-glazed doors and windows. However, it's generally an easy fix. It is caused by an absence of air circulation around the window, and typically is seen in rooms like bathrooms or kitchens. The most obvious sign of condensation is droplets of water appearing on the glass surface. These droplets will disappear quickly when the window is heated up by sunlight. However, if the issue persists, it's worth looking further.

There is also the sound of the sound of water drip. This is most likely because of a broken seal between the two glass panes. If you hear this sound, it is highly recommended since it will prevent cold drafts from entering your home. This kind of issue can cause mold in the long run, so it is best to fix the window as soon as you can.

A professional will inspect your window and suggest the best option. Professional firms will remove the glass that is affected and blow hot air between the two panes. This will evaporate any moisture that remains and ensure that a high-quality seal is reapplied.

The windowpane seals failing are the main cause of condensation problems with double glazing. When the window seal fails it allows cool air to get into double-paned glass windows, making them fog. If this occurs it's possible that simple fixes could assist, but in many instances, the best option is to replace the window.

A spacer bar is usually located between the two glass panes in most double-glazed windows. The spacer bar is filled with desiccant, which absorbs any moisture that may be present, thereby preventing it from reaching the glass panes and causing condensation. This spacer bar is prone to breaking or cracking and it's often necessary to replace your entire window.

It is possible to complete repairs yourself if you have the appropriate tools, but it's usually better to hire an experienced professional to carry out this for you. This will not only save you a great deal of time, but it will also ensure that your double-glazing is repaired properly and of the highest possible quality. Employing a reputable tradesperson could also mean you receive some form of guarantee for the work carried out which you wouldn't get with a DIY job.

Shattering

Double glazing is an ingenuous product that lets homeowners reduce heating costs while keeping their homes warm. It isn't impervious to damage and there are issues that can arise periodically. In certain instances the faults could be dangerous if not addressed promptly enough.

If you spot any issues with your double-glazing, which could put your family in danger, it's important to address them as quickly as possible. Problems such as misting or water leaks can compromise the effectiveness of windows and cause them to appear ugly.

Repairing double-glazed windows is typically cheaper than replacing them. If you see any indications of problems with your double glazing, it's worthwhile to research local companies that specialize in double glazed window repairs and requesting quotes. Be aware that the most affordable quote isn't always the most effective and ensure that your chosen company offers a warranty with their work.

A double-glazed window will be sold in an Insulated Glass unit (IGU). The Insulated Glass Unit (IGU) is composed of two glass panes, with a space in between, and a rubber gasket that stops water from entering the gap. Certain IGUs also contain a gas such as Argon that helps to prevent heat from getting out of your home, thereby saving you on energy costs.

If one of the IGU panes is damaged, then you can purchase a replacement from a window manufacturer and then fitted to the frame. This is usually cheaper than replacing the entire window and is more cost-effective for a large number of households.

Depending on the type of window you own and the condition of the frame, it may be possible to repair the damaged window. This is typically the case when it has only developed a few small cracks, but it isn't damaged. If the double-glazed window is completely shattered then it is recommended to replace both the glass unit and the window sash.
