Can Double Glazed Windows Be Repaired?
If you recently installed double glazing in your home and it is beginning to show signs that they are in danger, you might wonder if they can still be repaired.
You might be able to get your double glazing covered under warranty depending on the problem and the date when you bought it.
Broken Panes
If a window pane becomes cracked or broken it allows air to move more easily, which reduces the windows' effectiveness as an insulation and a barrier against the elements. Based on the season, this can cause cold or hot air to escape or enter your home, which can increase heating and cooling costs.
If the crack isn't too deep, you might be able to use a strong-hold adhesive tape. This is temporary fix and will only stop the crack from getting more severe. To ensure the best results, a professional window repair company should be contacted to fix any damaged glass that is present in your double glazed windows.
Removing a damaged window pane yourself can be challenging and potentially dangerous. If the crack is too big to grasp then try pressing strips of masking tape in a crisscross pattern before trying to remove it. If the crack isn't too large, you can employ a slicing tool to cut the glass away from the frame. Be sure to wear gloves and a face mask when cutting glass. When the pane is cut free, you will need to lay it flat on several layers of newspaper to stop any pieces that might fall.
To install a new pane you'll need to buy replacement glass and then prepare the frame. Find the opening of the frame and subtract 1/16 to 1/8 inches in both directions to make sure that your new pane is a good fit. Then have your replacement glass cut according to this measurement at your 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 manner that will allow expansion and contraction while still keeping the putty level against the glass.
After the new pane has been placed, spread a thick layer of your preferred glazing compound with the help of a putty knife. You can use a linseed oil-based putting like Sarco, or a cheaper product such as Dap glazing compound. Fill any gaps that exist between the new pane and frame using the appropriate compound. Smooth the compound on the new pane to ensure it is even and level.
Water Leaks
The presence of water leaks around the frame or sash is a common issue that can occur when window sealant has deteriorated and needs to be replaced. Water leaks in the window can damage the drywall or plaster and cause damp walls.
A good double glazed window has a gasket that firmly compresses when the sash is closed. Any water that hits this area should be drained away via the weep holes at the bottom of the frame. Sometimes, the weep hole may be blocked by dirt and debris. The weather stripping could need to be replaced.
Another source of water leaks is the lintel that supports the brick above the window. Installers who built the house may not have been aware of the importance of allowing the lintel drain properly, or have covered it in concrete, which left a gap in which rainwater can enter and accumulate, causing dampness or rot on the wood. The builders may have angled fascia boards above the windows to ensure water is directed correctly. This will prevent water getting into the building.
Another leak could be the gap between the glass panes in the double-glazed unit. A damaged seal could have caused argon gas or krypton that is supposed to be between the glass panes to provide insulation to leak. Although this isn't the most serious problem with leaky windows however, it could affect energy efficiency. It is important to address the issue in the shortest time possible. In this instance replacing double glazing could be appropriate. A professional will conduct a full evaluation and reveal the source of the leak. They will also recommend solutions. They can also advise if it is better to fix or replace the window. They will also be able to provide you a price for any work required.
Condensation
Condensation can be a problem with older double-glazed windows and doors. However, this is generally an easy fix. This is due to an absence of air circulation around the windows. It is common in areas like kitchens or bathrooms. The most obvious evidence of condensation is the appearance of water droplets forming on the glass surface. These droplets will evaporate quickly when the window is heated up by sunlight. If the issue persists, it's worth looking into further.
You can also hear water drip. This is likely due to a damaged seal between the two glass panes. Repairs are highly recommended if there is this sound. This will stop cold drafts entering your home. This type of issue can also lead to mould in time, so it is best to have the window repaired as quickly as possible.
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 dry out any remaining moisture and ensure that a quality seal is applied.
Double condensation on glazing is caused by defective windowpane seals. When the window seal fails it allows cool air to get into double-paned glass windows, making them fog. If this occurs, it is possible that simple fixes will help, but in many instances, the best option is to replace the window.
The majority of double-glazed windows feature an "espacer" bar that is placed between the two glass panes. This spacer bar is filled with desiccant, which absorbs any moisture that may occur, therefore preventing it from reaching the glass panes and causing condensation. This spacer bar is prone to cracking or breaking, and it's often necessary to replace the entire window.
You can do some repairs yourself with the right tools. However, it is more common to hire a professional who is trained to do this. This will not only save you a great deal of time, but it will also ensure that your double glazing is repaired correctly and of the best quality possible. Employing a reputable tradesperson could also mean that you get some kind of assurance for the work that is completed which you wouldn't get with a DIY job.
Shattering
Double glazing is an amazing innovation that allows homeowners to save money on heating bills, whilst keeping their homes warm and comfortable. But it's not impervious to damage and from time to time issues may arise. These flaws could be dangerous in some instances when they aren't addressed quickly.
As such, if you have noticed any problems with your double glazing that could put your family members at risk, then it's important to fix them as soon as you can. Faults like misting and water leaks can reduce the effectiveness of windows and cause them to look ugly.
Repairing double-glazed windows is usually cheaper than replacing them. If you've noticed any indications of problems with your double glazing, you should consider researching local companies that specialise in the repair of double glazed windows and asking for quotes. The cheapest quote may not be the best option. Make sure that the company you choose offers a guarantee with their work.
A double-glazed window will be sold in an Insulated Glass unit (IGU). The Insulated Glass Unit (IGU) is comprised of two glass panes, with an opening in between and a rubber gasket that stops water from entering the gap. Certain IGUs contain the gas argon. It prevents heat from escaping the home and saves money on energy costs.
If one of the IGUs is damaged, a replacement pane can be purchased from a window manufacturer and then fitted to the frame. This is typically less expensive than replacing the entire window and is cost-effective for many households.
Based on the type of window you have and the condition of the frame, it may be possible to simply repair the damaged window. If the glass has formed only a few small chips, but not been damaged, this is typically the situation. If your double glazed window has completely broken and is cracked, then it's best to replace the entire glass unit and window sash.
