Can Double Glazed Windows Be Repaired?
If you've recently had double glazing installed in your home and are beginning to show signs of failing, you may be wondering if they are able to be repaired.
Depending on what the problem is and the date you bought them from, you may be eligible to receive your double-glazed windows replaced under warranty.
Broken Panes
If a window's pane is cracked or broken air can enter more easily. This decreases the effectiveness of the window as an insulation barrier and against the elements. Depending on the time of year it can allow warm or cold air to escape or enter your home, which can increase heating and cooling costs.
If the crack in the double glazing isn't that deep, it might be possible to simply apply a strong-hold tape. This is a temporary solution however, and could only stop the crack from growing. To get the most effective results, a professional window repair service should be called to repair any damaged glass that is present in your double glazed windows.
Removing a damaged window pane yourself can be tricky and dangerous. If the crack is large and difficult to remove, you can try applying strips of masking tap in a crisscrossing design. If the crack isn't too large you can use a razor to cut the glass away from the frame. Be sure to wear gloves and a face mask when cutting glass. After the pane has been cut it is necessary to place it flat on a few layers of newspaper to stop any pieces that might fall.
To install a new pane, you'll need to purchase replacement glass and set up the frame. To ensure that the new pane fits properly take a measurement of the opening of the window frame and subtract between 1/16 and 1/8 inches on both sides. Then, you can have your replacement glass cut to this measurement at your local glass shop or at a hardware store. If you have wooden frames, buy points for glaziers from a local hardware store to place them on the outside of your new pane. Place the points in a way that they allow expansion and contraction while keeping the putty in place against the glass.
After the new pane is in place, spread a thick layer of your chosen glazing compound with the help of a putty knife. You can use a linseed oil-based putty like Sarco, or a cheaper product like Dap glazing compound. Fill any gaps between the frame and pane using the compound you choose. Smooth the compound over your new pane to make sure it is even and level.
Water Leaks
Water leaks around windows' frame or sash are a typical problem. This happens when the window sealant is deteriorated and must be replaced. Water leaks around windows can cause damage to the plaster or drywall and lead to damp walls.
A double-glazed window that is of good quality has a gasket that expands with force when the sash is closed. The water that is absorbed by the area should be drained out through the weepholes of the frame. However, sometimes the weep holes get blocked by a build-up of dirt and debris or the weather stripping around the window could require replacement.
Another source of water leaks is the lintel which is a support for the brick that is above the window. The builders who constructed the house may not have realized the importance of allowing the lintel drain properly, or they may have covered it with concrete, which left a gap in which rainwater could enter and accumulate, and cause dampness or rot to the wood. The builders could have placed an angled fascia board above the windows to ensure water is directed properly. This will stop water from entering the building.
Another source of leaks 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 panes to provide insulation has leaked out of the windows because of the seal being worn out. Although this isn't a particularly serious leaky window problem however, it could affect energy efficiency and should be dealt with as soon as it is possible. In this instance, replacement double glazing may be a good idea. A professional can conduct an exhaustive assessment and identify the cause of the leak. They will also recommend solutions. They will be able to tell you whether it makes sense to repair the window or replace it completely. They can also give you an estimate for any work that is needed.
Condensation
Condensation can be a problem with older double-glazed doors and windows. However, it's typically a simple fix. It is caused by the lack of air flow around the window and often occurs in rooms like kitchens or bathrooms. The most evident sign of condensation is water droplets forming on the glass surface. These droplets will rapidly disappear when the glass is heated by sunlight. However, if the problem persists, it's worth looking further.
Another indicator of condensation is if you can hear water dripping. This is most likely due to a damaged seal between the two glass panes. If you hear this sound, then repair is highly recommended as it will stop cold drafts from entering your home. This kind of issue could cause mould in time, so it's best to get the window repaired as soon as you can.
A professional can inspect your window and suggest the best solution. Professional firms will remove the glass affected and blow hot air between the two panes. This will eliminate any moisture that remains and ensure that a good seal will be reapplied.
Double condensation in the glazing is caused by windowpane seals. Cool air gets into double-paned windows when the window seal is damaged, causing them to become cloudy. If this happens it is possible that simple fixes will help, but in many instances, the best option is to replace the window.
A spacer bar is typically found between the two glass panes of most double-glazed windows. The spacer bar is a source of desiccant, which absorbs any moisture and blocks it from getting into the glass. This spacer bar is prone to breaking or cracking, and it's often necessary to replace the entire window.
It is possible to carry out some repairs yourself if have the right tools, however it is generally better to employ an experienced professional to carry out this for you. You will save a lot of time and ensure that the double-glazing is repaired properly. Employing a reputable tradesperson could also mean that you get some form of guarantee for the work done that you would not get from a DIY job.
Shattering
Double glazing is a wonderful 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 faults can be dangerous in certain instances when they aren't addressed quickly.
If you find any issues with your double-glazing, which could put your family in danger, it's crucial to fix them as quickly as you can. Issues such as misting or leaks of water can affect the performance of windows, and can leave them looking unsightly.
Repairing double-glazed windows is usually cheaper than replacing them. If you see any indications of problems with your double glazing it is worth researching local companies who specialize in double-glazed window repairs and asking for estimates. Be aware that the lowest price isn't always the most effective and ensure that your chosen company offers a warranty with their work.
When a double-glazed window is sold in the market, it will be housed inside an Insulated Glass Unit (IGU). It is made up of the two glass panes, a space between them and a rubber seal that keeps water from getting into the insulating gap. Some IGUs contain the gas argon. It keeps heat from leaving the home and saves money on energy costs.
If one of the IGU panes is damaged, a replacement can be bought from a window maker and then installed on the frame. This is typically less expensive than replacing the whole window and is much cheaper for most households.
It is possible to repair the damaged pane based on the kind of frame and condition of your window. This is usually the case if it's only developed a few tiny cracks, but has not damaged. If the double-glazed window is completely shattered then it is recommended to replace both the glass unit and the window sash.
