7 Simple Secrets To Totally Rocking Your Repairs To Double Glazed Windows
Can Double Glazed Windows Be Repaired?
If you've recently had double glazing installed in your home and they are beginning to show signs of failure, you may be wondering if they could be repaired.
You might be able to get your double glazing covered under warranty, based on the issue and the date you purchased it.
Broken Panes
If a window's pane is broken or cracked, air can pass through more easily. This reduces the effectiveness of the window as an insulation barrier and against the elements. Depending on the time of year it can allow hot or cold air to enter or escape your home, causing an increase in heating and cooling costs.
If the crack in the double glazing isn't that deep, it might be possible to just apply a strong-hold tape. This is only a temporary solution, though, and it will only stop the crack from growing. To get the best results, a reputable window repair service should be contacted to fix any damaged glass in your double glazed windows.
The process of replacing 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 across it in a crisscrossing fashion prior to trying to take it off. If the crack isn't too large to be able to hold it in place and use a blade to remove it from the frame. Be sure to wear gloves and a face mask when cutting glass. Once the pane is free it is necessary to place it flat on several layers of newspaper to keep any pieces that fall.
To install a new pane you'll need to buy replacement glass and prepare the frame. To ensure that the new glass is a good fit, measure the opening of the window frame and subtract between 1/16 and 1/8 inch on both sides. Cut your replacement glass at a local hardware store or glass shop according to this measurement. If you have wooden frames, buy some points for glaziers from a hardware store to install on the edges of your new pane. Place the points in a way they can allow for expansion and contraction, while keeping the putty flush against the glass.
Once your new pane is set and you are happy with it, apply a thick layer of your preferred glazing compound using the help of a putty knife. You can make use of a linseed oil-based glue such as Sarco, or a cheaper product like Dap glazing compound. If there are gaps between your new pane and the frame then fill them in using the chosen compound. Make sure you smooth the compound to ensure that it is even and level around the pane.
Water Leaks
The occurrence of water leaks around the frame or sash is a common issue that happens when window sealant has deteriorated and needs to be replaced. Water leaks in the window could damage the drywall or plaster and lead to damp walls.
A good quality double glazed window has a gasket that firmly compresses when the sash is shut. The water that is absorbed by this area must be drained through the weepholes in the frame. Sometimes, the weep hole may become blocked due to dirt and other debris. The weather stripping may need replacing.
Another possible cause of water leaks is the lintel that holds the bricks above the window. The people who built the house may not have understood that this lintel should be allowed to drain properly or they could have just put it in concrete and left a gap where rainwater can be able to enter and collect around the window, creating dampness in the wall or wood rot. The builders may have angled fascia boards above the windows to ensure that water is directed properly. This will prevent water entering the building.
Another potential leak source is the gap between the glass panes of double-glazed units. It's possible that the gas argon or Krypton that is supposed to be in between the glass to provide insulation has escaped out from the windows due to a worn out seal. Although this isn't the most serious issue with leaky windows but it could have an impact on energy efficiency. It should be addressed as soon as is possible. In this situation replacement double glazing might be the best option. A professional can conduct an extensive evaluation, let you know where the leak is coming from and suggest a solution. They can also advise whether it is best to fix or replace the window. They will also be able to provide you a price for any work that is required.
Condensation
Condensation may be a problem with older double-glazed windows and doors. However, this is usually a simple fix. This is due to a lack 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's surface. The droplets will quickly evaporate when the window is heated by sunlight. However, if the issue persists it is worth investigating further.
You can also hear the sound of water drip. This could be because of a damaged seal between the two panes of glass. If you hear this sound then repair is highly recommended since it will block cold drafts from entering your home. This type of problem may also lead to mould in time, so it is best to fix the window promptly.
A professional inspection of your window for condensation is the best method of tackling this issue, as they will be able to suggest the best method of action. The majority of professional companies will take off the affected window and pipe hot air into the space between the two. This will dry out any remaining moisture and ensure a good seal is reapplied.
Windowpane seals that fail are the primary 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 to fog. Simple fixes may help, but the best solution to this problem is to replace the windows.

The majority of double-glazed windows feature spacer bars that sit between the two glass panes. This spacer bar is filled with desiccant which sucks up any moisture that could occur, thus stopping it from getting to the glass panes and causing condensation. However, this spacer bar may break or crack and in this instance, it is typically necessary to replace the entire window.
You can do some repairs yourself using the appropriate tools. However, it is usually better to hire someone who is skilled in doing this. This will not just save you a good amount of time, but it will also ensure that your double glazing is repaired correctly and of the highest quality. A reputable tradesperson will also offer a guarantee on the work they have done, which you would not receive if you tried to do it yourself.
Shattering
Double glazing is an innovative product that allows homeowners to reduce heating costs while keeping their homes warm. It's not impervious to damage, and issues can occur from time to time. These flaws could be dangerous in certain instances if they are not corrected promptly.
If you have noticed any problems with your double glazing that could put your family at risk, then it's important to fix them as soon as you can. Faults like misting and leaks of water can affect the performance of windows and make them appear ugly.
Repairing double-glazed windows is typically more cost-effective than replacing them. If you've noticed any signs of issues with your double glazing, it's worth searching for local companies that specialize in the repairs of double-glazed windows and asking for estimates. Remember that the cheapest quote isn't always the best option and ensure that the company has a warranty on their work.
If a double-glazed window is sold in the market, it will be housed inside an Insulated Glass Unit (IGU). The Insulated Glass Unit (IGU) is made up of two glass panes with an opening in between and a rubber gasket which prevents water from leaking into the gap. Some IGUs also contain a gas like argon, which helps keep heat from escaping your home, thereby saving you on energy costs.
If one of the IGUs is damaged an alternative pane can be purchased from a window manufacturer and then fitted to the frame. This is usually cheaper than replacing the entire window and is cost-effective for many households.
Depending on the type of window you have and the condition of the frame, it may be possible to repair the damaged window. If the glass has developed just a few tiny chips, but not been damaged, this is typically the case. If your double glazed window is completely cracked and is cracked, then it's best to replace the entire glass unit as well as the window sash.
