How to Deal With Double Glazed Repair
You should ensure that your double-glazed window frames are regularly inspected, especially if they are expanding or shrinking. This will reduce the risk of drafts.
If you notice condensation between the panes, this is an indication that the seal is failing and has to be replaced. Replacing the seal will not only reduce condensation, but it will also reduce energy costs.
Broken or cracked panes
Double glazing isn't indestructible. It is susceptible to developing problems that could reduce the efficiency of energy. Repairing double glazing is a relatively straightforward process, but the proper tools and knowledge are required to carry out high-quality repairs. It is generally recommended to use a professional firm to complete the task rather than trying it yourself.
A broken or cracked window is the most frequent issue for double-glazed windows. A knock or blow from outside can cause this, as can an attempt to open a closed window that is stuck. The glass could break or crack into smaller pieces, based on the size of the crack and the force that is applied to it.
If windows with double glazing are susceptible to cracking, it can be repaired by using a form of putty or a special tape. This will stop the crack from extending or getting worse. It will block any moisture, wind or other elements from entering the home through the cracks.
Condensation in double-glazed windows is a different issue that is common and is usually the result of a break of the window seal. It is a natural process that can occur due to varying temperatures and weather conditions, so it is important to check that your windows are still under warranty before attempting to repair them.
Typically, this issue will be covered by the company that you purchased your double glazing from so it is important to contact them immediately and explain the issue clearly. This is best written down, rather than by phone or text. Always keep a copy.
If you want to try and fix a damaged or misted window by yourself, a popular method is to drill an opening in the centre of the affected window. A special desiccant is put in to absorb moisture and this can help the condensation issue to get rid of itself. However this is an interim solution, and it is recommended to have your double-glazed windows replaced by new units whenever possible.
Misty Panes
When double-glazed windows start getting misty, it can be a real trouble and can cause major disruption in your home. Fortunately, it can be fairly easy to fix the issue once you know what's causing it. In most cases the cause of the issue is a failure of the seals between the window panes, which allows moisture to enter. Poor installation, drainage issues or even faulty seals by the window manufacturer can cause this problem.
Standard sealed units are made up of two glass panes with a hollow spacer bar sandwiched between them (shown in the above image). The inner face of this bar is perforated, and the bars that are used as spacers are filled with a desiccant which helps to absorb any moisture that comes into the unit. The two glass panes will be sealed and the whole unit will be injected with gas in order to increase its thermal efficiency.
As you can imagine, if a sealed unit fails then moisture could get between the panes and this could cause condensation and mist. This can also result in heat escaping from your home, which could result in a significant amount of money being lost due to energy bills.
Repairing a misted window is a tricky job that should not be attempted by a person who isn't well-versed in the glazing and construction industries. If you are willing to take on the challenge, it's possible to fix a sealed window that has been misted by putting in moisture-absorbing desiccant into the space between the glass panels.
Remember that this is only a temporary fix and the condensation might be back. The process will have to be repeated. It is more efficient to replace the misty unit. It will also be cleaner and faster. A replacement will restore the original insulation to your property, which is not possible with a repair. If you're experiencing misty windows and condensation, we suggest contacting an experienced company that can provide double glazing. While you wait, keep your windows as dry and clean as you can.
Water Leaks
No matter if they are brand new or old, double glazed windows should not leak. Leaking windows aren't just an inconvenience, but they could cause severe damage to your home, including mold growth and structural damage as well as higher heating and cooling costs. Contact a professional window company as soon as you suspect a issue.
Window leaks are usually indications of a problem with the seals between the panes of glass. If you notice condensation between the glass panes, it is a sign that the seal between the two panes has become weaker. The moisture is now leaking through the insulating space between the two panes. While repair double glazing windows is normal, if it is persistent and becomes visible on the interior or exterior of your home, it's time to have a repair service in.
Another reason for leaks is that water collects at the bottom of the frame of your window. This can be an indication of blocked drain holes or flashing that is not properly installed or a sloped sill. It is simple to clear a blocked drain hole using a coat hanger. With roofing caulk, you can repair flashing that is not properly installed. A wrong pitch could be the reason of an inclined window sill to one side. A professional window repair company will be able to determine the root of the problem and offer a fast, cost-effective solution.
It is not uncommon for UPVC windows that are older to break or leak. However, it is more cost-effective and efficient to hire a double glazing repair service. They can bring your windows' appearance and function to the way they were when they first were introduced. They can also replace hinges, handles and locks if necessary. Professional window repair companies will offer you a guarantee on their work. You wouldn't get this if you tried to fix windows on your own.
It is difficult to open
If you notice that your windows are becoming more difficult to open, call the company where you purchased the windows. In most instances, a simple repair can fix the problem. If the issue persists then you should think about replacing your windows with new contemporary designs. New double glazed windows offer state-of-the-art features that will keep your home safe and warm, including slimline uPVC or aluminium frames with advanced insulation that stops heat from escaping, as well as innovative security equipment to stop intruders from entering your home.
Another indication that your double glazing requires repairs is condensation between the glass panes. This is caused by a failure of the seals that separate the two panes. Inert gases are supposed to escape between the panes of glass and replaced by moist air. This keeps your windows airtight and energy efficient. If this doesn't happen, the seals may have become less effective over time due to weather conditions or other factors.
A draft coming from a double-glazed window could also be a sign that the seals are failing which means cold air is leaking in to your home. This can lead to more energy costs as your heating system will have to work harder to maintain the temperature of your home.
In some cases the draught could be fixed by lubricating the hinges, handles or mechanisms of windows or doors that are double-glazed. However, it is important to keep in mind that this is only a temporary fix and if the issue persists, then you'll need to seek out the experts.
You can also add ventilation systems, such as extractors, air bricks, or vents in your windows and doors to assist with condensation issues. It is also important to allow double-glazed windows and doors to 'breathe' by leaving them open as much as possible, which is possible with trickle vents.
