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 could be repaired.
Depending on what the issue is and how long ago you bought them from the store, you might be eligible to receive your double-glazed windows replaced under warranty.
Broken Panes
If a window pane becomes damaged or cracked it allows air move more easily, which reduces the windows' effectiveness as an insulation and a barrier against the elements. Depending on the season this could cause hot or cold air to enter or escape your home, increasing heating and cooling costs.
If the crack isn't too deep, you might be able to use a strong-hold adhesive tape. This is a temporary fix, though, and it may only prevent the crack from becoming worse. A reputable window repair service can repair any damaged glass on double-glazed windows.
The process of replacing a damaged window pane yourself is tricky and dangerous. If the crack is too large to grasp and hold, try putting strips of masking tape across it in a crisscross pattern before trying to remove it. If the crack is small enough, you can hold it in place and use a razor to cut it off from the frame. Wear gloves and a mask when cutting the glass. When the pane is cut free it is necessary to lay it flat on several layers of newspaper to stop any pieces that might fall.
In order to install a replacement pane you'll need to prepare the frame and purchase replacement glass. Measure the opening of the frame and subtract 1/16 to 1/8 inch in both directions to ensure that the new pane will fit properly. Then, you can have your replacement glass cut according to this measurement at your local glass shop or hardware store. If you have wooden frames, buy points for glaziers from a local hardware store to place them along the edge of your new pane. Position the points so that they allow for expansion and contraction, while keeping the putty in place against the glass.
After your new pane is in place, spread a thick layer of your chosen glazing compound using a putty knife. Make use of a linseed-oil-based glue like Sarco or a less expensive product like Dap glazing compound. If you have any gaps between your new pane and the frame, fill them in with the chosen compound. Make sure you smooth the compound to ensure it is even and level all around your pane.
Water Leaks
The presence of water leaks around the frame or sash is a common problem that occurs when window sealant has deteriorated and requires replacement. Water leaks can cause damage to the plaster and drywall surrounding the window. They can also result in damp or moldy walls that need to be restored as quickly as is feasible.
A good quality double glazed window will have a gasket that is able to compress when the sash is closed. The water that enters this area must be drained through the weepholes in the frame. Sometimes, the weep holes be blocked due to dirt and debris. Or, the weather stripping might need to be replaced.
Another potential culprit of water leaks is the lintel which holds the bricks over the window. The builders who built the house may not have been aware of the importance of allowing the lintel to drain properly, or they may have covered it in concrete, leaving a gap through which rainwater could enter and accumulate, creating dampness or rot on the wood. The builders may have an angled fascia board above the windows to ensure water is directed correctly. This will stop water from getting into the building.
Another potential leak source is the gap that exists between the glass panes in double-glazed units. It is possible that the gas argon or Krypton that should be positioned between the glass to provide insulation has leaked out of the windows due to a worn out seal. While this isn't the most serious leaky window problem it can affect energy efficiency and must be taken care of as soon as is possible. In this instance double glazing replacement could be necessary. A professional can conduct an exhaustive assessment and let you know the source of the leak. They can also suggest 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 necessary work.
Condensation
Condensation is a frequent issue with older double-glazed doors and windows, but it can be easily fixed. This is due to the lack of air circulation around the window, and typically happens in rooms such as bathrooms or kitchens. The most obvious indication of condensation is droplets of water forming on the glass surface. These droplets will evaporate quickly when the window is heated by sunlight. If the issue persists, it's worth looking into further.
Another indicator of condensation is if you hear water drips. This could be due to a broken seal between the two glass panes. If you hear this sound, it is highly recommended since it will block cold drafts from entering your home. This kind of issue can also lead to mould in the long term, so it is best to have the window repaired as soon as possible.
A professional inspection of your window for condensation is the most efficient method of tackling this problem, as they can recommend the correct course of action. Professional companies will remove the glass affected and blow hot air between the two panes. This will eliminate any remaining moisture and ensure that a quality seal is reapplied.
The windowpane seals failing are the main reason for condensation issues in 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 is possible that simple fixes could help, but in many cases, the best solution is to replace the window.
A spacer bar can be found between the two glass panes that are found in the majority of double-glazed windows. This spacer bar contains desiccant that absorbs any moisture and stops it from reaching the glass. The spacer bar is susceptible to cracking or breaking, and it's often necessary to replace your entire window.
It is possible to do repairs yourself if you have the right tools, but it is generally better to employ an experienced professional to carry out this for you. You'll save a lot of time and ensure that the double glazing is repaired properly. A reputable tradesperson will also provide you with a warranty on the work they have done, which you would not get if you were to repair it yourself.
Shattering
Double glazing is a revolutionary product that lets homeowners reduce heating costs while keeping their homes warm. It's not impervious to damage and there are issues that can arise occasionally. In some instances these flaws could be dangerous if they are not addressed promptly enough.
If you spot any issues with your double-glazing that could put your family in danger, it's important to fix them as soon as possible. Issues like misting and leaks of water can affect the effectiveness of windows and make them appear ugly.
Repairing double-glazed windows is usually cheaper than replacing them. If you see any indications of problems with your double glazing it is worth looking into local companies that specialize in double-glazed window repairs and getting estimates. Be aware that the most affordable quote isn't always the best option and make sure that the firm offers a guarantee on their work.
When a double glazed window is sold in the market, it will be housed in an Insulated Glass Unit (IGU). The Insulated Glass Unit (IGU) is composed of two glass panes that have a space in between, and a rubber gasket that prevents water from leaking into the gap. Some IGUs also contain a gas like argon, which helps keep heat from getting out of your home, thus cutting down on energy costs.
If one of the IGUs is damaged, a replacement pane can be purchased from a window manufacturer and fitted to the frame. This is normally far cheaper than replacing the whole window and is far more cost-effective for most households.
It could be possible to repair the damaged pane depending on the kind of frame and condition of your window. If the glass has formed only a few tiny chips, but not been shattered, this is usually the situation. If your double glazed window has completely shattered and cracked, it's likely to replace the entire glass unit as well as window sash.
