Can Double Glazed Windows Be Repaired?
If you have recently had double glazing installed in your home and are beginning to show signs of failing, you may be wondering if they can be fixed.
You might be able to get your double glazing covered under warranty, based on the issue and the date when you bought it.
Broken Panes
When a window pane is broken or cracked air can enter 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 warm or cold air to escape or enter your home, causing an increase in the cost of cooling and heating.
If the crack in your double glazing is not that deep, it might be possible to just apply a strong-hold tape. This is temporary fix, and could be able to stop the crack from getting worse. To get the most effective results, a professional window repair company should be called to repair any damaged glass in your double glazed windows.
Removing a damaged window pane yourself can be tricky and dangerous. If the crack is too big to grasp and hold, try putting strips of masking tape across it in a crisscrossing fashion prior to trying to remove it. If the crack isn't too large you can make use of a razor to remove the glass from the frame. Wear gloves and a mask while cutting the glass. When the pane is cut free you must place it flat on a few layers of newspaper to stop any pieces that might fall.
To install a replacement glass you'll need to prepare the frame and buy replacement glass. Take measurements of 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 the replacement glass cut according to this measurement at your local glass shop or at a hardware store. If you have wood frames, buy some points for glaziers at an hardware store to place along the edges of your new pane. Position the points so that they allow expansion and contraction while keeping the putty in place against the glass.
Spread a thick layer of it with a putty knife after your new pane has been installed. Make use of a linseed oil-based putty such as Sarco or a less expensive product such as Dap glazing compound. If you notice any gaps between your new pane and the frame, fill them in with the compound you choose. Be sure to smooth the compound so that it is even and level around the pane.
Water Leaks
Water leaks in a window's frame or sash can be a frequent problem. This occurs when the window sealant is worn out and needs to be replaced. Water leaks can damage the plaster and drywall surrounding the window, and can lead to damp or spongy walls that require to be restored as quickly as is possible.
A double-glazed window that is of good quality will have a gasket which expands with force when the sash is closed. The water that enters this area should be drained out through the weepholes of the frame. Sometimes the weep hole can become blocked due to dirt and other debris. Or, the weather stripping may need replacing.
Another potential culprit of water leaks is the lintel that holds the bricks above the window. The builders who built the house may not have been aware of the importance of allowing the lintel drain properly, or have covered it with concrete, leaving a gap through which rainwater could get in and then pool around creating dampness or rot on the wood. The builders may have bent fascia boards over the windows to ensure water is directed properly. This will stop water from getting into the building.
Another possible leak source is the gap between the glass panes in a double-glazed unit. It is possible that the gas argon or Krypton that is supposed to be in between the glass to provide insulation has escaped out of the windows due to the seal being worn out. Although this isn't the most serious leaky window problem it can affect energy efficiency and should be taken care of as soon as is possible. In this instance replacing double glazing could be a good idea. A professional can complete an exhaustive evaluation, letting you know where the leak is coming from and recommend solutions. They will also be able to advise whether it makes sense to fix the window or replace it completely. They can also give you an estimate for any work that is needed.
Condensation
Condensation is a frequent issue with older double-glazed doors and windows, but this can usually be easily fixed. This is due to a lack of air circulation around the window and often occurs in rooms like kitchens or bathrooms. The most obvious sign of condensation is water droplets forming on the glass surface. The droplets will disappear when the glass is heated by sunlight. If the issue persists it is worth investigating further.
There is also the sound of water drip. This is most likely caused by a leak in the seal between the two glass panes. Repairs are highly recommended if you notice this sound. This will prevent cold drafts entering your home. This type of problem may cause mould in time, so it's best to fix the window promptly.
A professional will inspect your window and suggest the best solution. The majority of professional companies will take off the affected pane and then pipe hot air into the gap between the two. This will dry out any remaining moisture and ensure a good seal is reapplied.
Failing windowpane seals are the main cause of condensation issues in double glazing. Cool air enters double-paned windows when the window seal fails, causing them to become cloudy. 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 located between the glass panes that are found in the majority of double-glazed windows. The spacer bar is filled with desiccant which sucks up any moisture that may be present, thereby preventing it from reaching the glass panes and creating condensation. This bar is susceptible to cracking or breaking, and in most cases, you'll need to replace the entire window.
You can repair some of the issues yourself using the appropriate tools. However, it is usually better to hire someone who has been trained to do this. You will save a lot of time and ensure that the double glazing is repaired correctly. A reliable tradesperson can be a good idea as it will give you some kind of assurance for the work done that you would not get from DIY work.
Shattering
Double glazing is an amazing innovation that allows homeowners to save money on heating costs, while keeping their homes warm and comfortable. However, it's not indestructible and, from time to time, issues may arise. These issues can be dangerous in some instances if they are not corrected quickly.
If you spot any issues with your double-glazing, which could put your family in danger, it is important to address them as quickly as you can. Issues like misting and water leaks can compromise the performance of windows and make them appear ugly.
It is often far cheaper to repair your double-glazed windows than to replace them completely. If window repairs near me see any indications of trouble with your double glazing, it's worth researching local companies who specialize in double-glazed window repairs and getting estimates. The most affordable quote might not be the best option. Be sure that the company you choose has a guarantee with their work.
Double-glazed windows are sold as an Insulated Glass unit (IGU). This is what consists of two glass panes, a space between them and the rubber seal that stops water from leaking into the insulating 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, it is possible to replace the pane purchased from a window manufacturer and fitted to the frame. This is usually less expensive than replacing the entire window and is far more affordable for the majority of households.
Depending on the kind of window you have and the condition of the frame, it may be possible to fix the damaged window. If the glass has formed just a few tiny chips, but not been shattered, this is usually the case. If your double glazed window has completely broken, then it's probably best to replace the entire glass unit as well as window sash.
