Can Double Glazed Windows Be Repaired?

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

You may be able get your double glazing under warranty based on the issue and the date you purchased it.

Broken Panes

If a window pane becomes damaged or cracked it allows air pass more easily, lowering the windows' efficiency as insulation and protection against the elements. Depending on the time of year this could cause cold or hot air to enter or escape your home, which can increase heating and cooling costs.

If the crack in the double glazing isn't very deep, it may be possible to simply apply a strong-hold tape. This is only temporary fix, and may be able to stop the crack from becoming more severe. A professional window repair service can repair any broken glass that has been smashed on double-glazed windows.

The process of replacing a damaged window pane by yourself can be challenging and potentially dangerous. If the crack is large and difficult to eliminate Try applying strips of masking tap in a crisscrossing pattern. If the crack is small enough, you can hold it steady and use a razor blade to cut it off from the frame. Wear gloves and a mask when cutting the glass. When the pane is cut free you must lay it flat on several layers of newspaper to keep any pieces that fall.

To install a new glass pane, you'll need to buy replacement glass and then prepare the frame. Measure the opening of the frame and subtract 1/16 to 1/8 inch in both directions to make sure that the new pane will fit correctly. Then, have the replacement glass cut to this measurement at a local glass shop or hardware store. If you have wooden frames, purchase points for glaziers from a hardware store to be positioned on the outside of your new pane. Be sure to position the points in a position that will allow expansion and contraction while still keeping the putty in a flat position against the glass.

After your new pane has been placed and you are happy with it, apply an even layer of your preferred glazing compound using a putty knife. You can use a linseed oil-based putty such as Sarco or a less expensive product like Dap glazing compound. If you notice any gaps between your new pane and the frame, fill them in with your chosen compound. Be sure to smooth the compound so that it is level and even around the pane.

Water Leaks

Water leaks around windows' frame or sash are a common problem. This occurs when the window sealant has damaged and requires replacement. Water leaks around the window can damage the drywall or plaster and lead to damp walls.

A high-quality double-glazed window will come with a gasket which firmly compresses when the sash is shut. The water that enters this area should be drained out through the weepholes in the frame. Sometimes the weep hole can be blocked by dirt and debris. Or, the weather stripping might need to be replaced.

The lintel above the window can also be a source of leaks. The builders who constructed the house may not have understood that this lintel must be let to drain properly or they could have just covered it with concrete, leaving a gap where rainwater can be able to enter and collect around the window causing dampness in the wall or wood rot. The builders may have angled fascia boards above the windows to ensure water is directed properly. This will stop water from getting into the building.

Another possible leak source is the gap that exists between the glass panes of the double-glazed unit. A worn seal could have caused argon gas or krypton that is supposed to be between the glass panes to create insulation to leak out. Although this is not the most serious issue with leaky windows however, it could have a negative impact on energy efficiency. It should be addressed in the shortest time possible. In this situation, double glazing replacement may be necessary. A professional will conduct a full evaluation and reveal the source of the leak. They can also suggest solutions. They will be able to tell you whether it makes sense to repair the window or replace it completely. They will also be able to provide you a price for any work required.

Condensation

Condensation can be a problem with older double-glazed doors and windows. However, it is generally an easy solution. This is due to an absence of air circulation around windows and is common in areas like kitchens or bathrooms. The most obvious evidence of condensation is the appearance of droplets of water appearing on the glass surface. The droplets will quickly evaporate when the window doctor is heated up by sunlight. If the problem continues it's worth investigating further.

Another sign of condensation is when you hear water drips. This is most likely caused by a leak in the seal between the two glass panes. If you hear this sound it is highly recommended since it will stop cold drafts from entering your home. This type of issue can cause mould in time, so it is best to have the window repaired as quickly as possible.

Having a professional inspect your window for condensation is the most effective approach to tackling this issue, as they can suggest the best course of action. Professional firms will remove the glass that is affected and blow hot air between the two panes. This will dry out 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. If the window seal is damaged, it allows cool air to enter double-paned windows, which makes them fog. If this happens it's possible that simple fixes will help, but in many cases, the best solution is to replace the window.

The majority of double-glazed windows feature an "espacer" bar that is placed between the two glass panes. The spacer bar is a source of desiccant, which absorbs any moisture and blocks it from getting into the glass. Unfortunately, this bar can break or crack and in this instance, it is often necessary to replace the entire window.

It is possible to complete some repairs yourself if you have the right tools, however it is generally better to employ an expert who is trained to do this for you. This will not just save you a good amount of time, but it will also ensure that your double glazing is repaired properly and of the best quality possible. Using a trusted tradesman can also mean that you get some form of guarantee for the work that is completed that you would not get from DIY jobs.

Shattering

Double glazing is an amazing innovation that allows homeowners to save money on heating costs, while keeping their homes warm and comfortable. However, it's not indestructible and, from time to time, problems can occur. In some instances, these faults may even be dangerous if they are not addressed promptly enough.

If you spot any issues in your double-glazing that could put your family in danger, it is important to address them as quickly as possible. Faults such as misting and water leaks can reduce the effectiveness of the windows and make them look unattractive.

It is often far cheaper to fix your double-glazed windows than to replace them completely. If you see any indications of trouble in your double glazing it is worthwhile to research local companies that specialize in double glazed window repairs and asking for estimates. Remember that the cheapest quote isn't always the best choice and ensure that the firm offers a guarantee on their work.

Double-glazed windows are sold in an Insulated Glass unit (IGU). It is comprised of two glass panes, the space between them, and a rubber seal that keeps water from leaking into the gap that acts as an insulation. Some IGUs contain Argon, a gas that prevents heat from escaping the house and helps save money on energy costs.

If one of the IGU panes is damaged, then a replacement can be bought from a window maker and then installed on 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 kind of window you own and the condition of the frame, it may be possible to simply repair the damaged part. If the glass has developed only a few small chips, but not been damaged, this is typically the case. If your double glazed window has completely broken, then it's probably best to replace the entire glass unit and the window sash.
