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 failing you may be wondering if they can be fixed.
You may be able to claim your double glazing repaired under warranty based on the issue and the date you purchased it.
Broken Panes
If a window's glass is broken or cracked air can flow through more easily. This reduces the effectiveness of the window as an insulation and protects against the elements. Depending on the season this could cause cold or hot air to escape or enter your home, increasing the cost of cooling and heating.
If the crack isn't too deep, you may be able to apply an adhesive tape with strong-hold. This is a temporary fix however, and it may only prevent the crack from getting worse. To ensure the best results, a professional window repair company should be contacted to fix any damaged glass on your double-glazed windows.
Removing a damaged window pane yourself can be difficult and risky. If the crack is too large to grasp, try pressing strips of masking tape in a crisscrossing pattern prior to trying to remove it. If the crack isn't too large you can use a razor to remove the glass from the frame. Wear gloves and a mask when cutting the 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.
In order to install a replacement pane it is necessary to make the frame ready and purchase replacement glass. To ensure that your new pane is properly fitted you must measure the opening of the frame and subtract between 1/16 and 1/8 inch on both sides. Then, have the replacement glass cut to this measurement at your local glass shop or at a hardware store. If you have wood frames, purchase points for glaziers from an hardware store to place around the edges of your new pane. Make sure to place the points in a position that will allow expansion and contraction while keeping the putty in a flat position against the glass.
Spread a thick layer using a putty blade once your new pane is installed. You can make use of a linseed oil-based glue like Sarco or a less expensive product such as Dap glazing compound. If you notice any gaps between your new pane and the frame you can fill them in with your chosen compound. Smooth the compound over your new pane to ensure it is level and even.
Water Leaks
Water leaks around windows' frame or sash are a common issue. This happens when the window sealant is deteriorated and must be replaced. Water leaks can cause damage to the plaster and drywall surrounding the window. They can also lead to damp or moldy walls that need to be repaired as soon as possible.
A double-glazed window of good quality will come with a gasket that is firmly compressed when the sash is closed. Any water that gets into this area must be drained away via the weep holes at the bottom of the frame. Sometimes the weep hole can be blocked due to dirt and other debris. Or, the weather stripping might need to be replaced.
Another possible cause of water leaks is the lintel, which holds the bricks above the window. The builders who built the house might not have understood the importance of allowing the lintel drain properly, or have clad it in concrete, leaving a gap through which rainwater could enter and get trapped, creating dampness or rot on the wood. The builders could have placed angled fascia boards above the windows to ensure water is directed properly. This will stop water from getting into the building.
Another leak could be the gap between the glass panes of double-glazed units. It is possible that the gas argon or Krypton that should be between the glass to provide insulation has escaped out from the windows due to the seal being worn out. While this isn't the most severe leaky window issue it can affect energy efficiency and should be addressed as soon as possible. In this case double glazing replacement might be necessary. A professional can conduct a full evaluation, let you know the source of the leak from and suggest a solution. They can also tell you whether it is better to repair or replace the window. They can also provide an estimate for any work required.
Condensation
Condensation is a concern with older double-glazed windows and doors. However, it is generally an easy solution. This is caused by a lack of air circulation around the window and often is seen in rooms like kitchens or bathrooms. Droplets of water on the surface of the glass are an obvious sign of condensation. These droplets will disappear quickly when the window is heated up by sunlight. However, if the problem persists, it is worth looking further.
Another indication of condensation is if you can hear water dripping. This is likely due to a broken seal between the two glass panes. Repairs are highly recommended if you notice this sound. This will stop cold drafts entering your home. This kind of issue can cause mould over time It is therefore recommended to have the window repaired as soon as you can.
A professional can examine your window and recommend the best solution. Professional firms will take off the glass affected and blow hot air between the two panes. This will evaporate any remaining moisture and ensure that a high-quality seal will be reapplied.
Double glazing condensation is caused by faulty windowpane seals. Cool air gets into double-paned windows when the seal is damaged and causes them to become cloudy. Simple fixes may help, but often the most effective solution is to replace the windows.
A spacer bar can be located between the two glass panes in most double-glazed windows. This spacer bar contains desiccant, which sucks up any moisture and stops it from reaching the glass. The spacer bar is susceptible to breaking or cracking and it's often necessary to replace your entire window.
It is possible to do some repairs yourself if have the appropriate tools, but it is generally better to employ a trained professional to do this for you. You will save a lot of time and ensure that the double glazing is repaired correctly. A reliable tradesperson can also mean you receive some form of guarantee for the work carried out that you would not get from a DIY job.
Shattering
Double glazing is an amazing technology that lets homeowners save money on heating bills while keeping their homes warm and comfortable. It isn't impervious to damage, and issues can occur occasionally. These issues can be dangerous in some cases when they aren't addressed promptly.
If you find any issues in your double-glazing that could put your family in danger, it's important to fix them as quickly as you can. Faults like misting and water leaks can compromise the efficiency of windows and cause them to look ugly.
It's often cheaper to repair your double glazed windows than to replace them entirely. If you've noticed any indications of issues with your double glazing, you should consider searching for local companies that specialize in the repair of double glazed windows and getting quotes. The most affordable quote might not be the best option. Make sure that the company you choose to work with 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 a space in between, and a rubber gasket which stops water from entering the gap. Certain IGUs contain the gas argon. It stops heat from escaping the home and saves you money on energy costs.
If one of the IGUs has been damaged, a replacement pane can be purchased from a window manufacturer and fitted to the frame. This is normally far cheaper than replacing the entire window and is far cheaper for most households.
Based on the type of window you have and the condition of the frame, it might be possible to simply repair the damaged window. If the glass has developed just a few tiny chips, but not been damaged, this is typically the case. If the double-glazed window has completely shattered then it is recommended to replace both the glass unit and the window sash.
