Double Glazed Window Repairs
Double glazing is a great investment for your home, however it can be a hassle if it isn't working properly. Luckily, most problems can be fixed and you don't need to replace your windows or doors.
Double-glazed windows comprise two glass panels that are separated by an extremely thin gap, filled with insulating gas, such as argon or krypton. This increases the efficiency of a window's heating.
Broken panes
While double-pane windows are more difficult to break than single-pane glass, they may crack or shatter. It's important to fix a broken pane in double glazing as quickly as you can to prevent the loss of energy and moisture.
Depending on the severity of the crack, you may choose to make an interim repair or more extensive epoxy repair. A temporary repair can stop further cracks from occurring and keep out cold and rain. A more extensive repair may make the crack stronger and provide a better seal.
To replace a double-pane damaged window, remove the frame and place it on an un-slip surface. Then, apply a grid of duct tape to the pane to prevent any glass pieces from falling off when you remove it. After the tape is installed, remove the old double-pane glass from the frame. Next clean the grooves and rabbet using a wire brush and vacuum or wipe with a damp cloth. Remove the wood molding, if required and scrape off all putty or metal glazing points prior to putting in the new pane. Apply silicone caulk to the rabbets and grooves in order to ensure a secure fit.
If you want to repair the cracks in your window yourself, begin by sanding the rabbet until it's smooth and clear of paint or gunk. You could also use a heat gun to soften any glazing or putty points. Once the rabbet has been cleaned, you can use a blade for a putty to push ropes into place. Make sure the putty has an even thickness and presses against the glass and frame in a uniform way.
If you prefer a long-term fix, an epoxy repair is a better option than replacing. This option requires more work and a longer wait time but it's more appealing and last longer than a quick temporary repair.
Condensation
Condensation is one of the most common double glazed window issues, however it doesn't necessarily mean that your windows are defective. The fact that your windows are showing condensation is a good sign because it means that your double glazing is performing what it is supposed to keep the cold out and letting the warmth in.
It's actually water vapour from your home that forms a layer on the glass's surface when you notice condensation. It's a normal phenomenon and isn't likely to cause any damage to your windows unless you let it remain on the glass for a long time.
The cause of internal condensation is usually too much humidity or low temperatures in the room. This creates cold surfaces, like windows and doors, to draw in moisture that is high in dewpoint (the temperature at which water transforms into liquid). Humidity is also inevitable around bathrooms and kitchens due to steam from showers or kettles as well as hot pots and pans used in cooking.
Do not hang wet clothes close to windows, and make sure your uPVC frames are well ventilated to prevent moisture buildup. Also, ensure that your double glazed windows are correctly insulated and installed with the proper gap (6mm is ideal) to maximize energy efficiency. You can also add one-way air vents to your windows to increase insulation. If you're still getting condensation, there's likely problems with the seals or gaskets and this is a job for an expert.
Draughts
A draughty window is an indication that the seal between the glass panes of your double-glazing has begun to leak, and is likely to require replacement. This will affect the insulation of your home and could result in an increase in energy costs and therefore it is important to act as soon as you spot this issue.
A window repair service will replace the sealed unit for you, while restoring the efficiency of your windows. They can also modify your existing frames to incorporate energy efficient features, such as gas-filled argon glass units that have thermal spacer bars, which will cut down on the loss of heat and reduce the cost of heating.
Draughts can also be caused by issues with the locking mechanisms of double glazed windows, so it's worth getting these checked out. It is common for older uPVC window lock mechanisms to become stiff as they the passage of time. This is easily fixed by lubricating your locks regularly with a specialist uPVC cleaner.
A professional double glazing business will ensure that the repair is done properly. They'll have the proper tools to make sure that your window is resealed and watertight. They can also fix any damage to the frame so that you can take advantage of your new double glazing.
Double-glazed windows are tough and long-lasting, however they can experience issues due to weather or wear and wear and tear. Contact your local double-glazing repair company whenever you notice any of these issues. You'll be glad you did it - a double glazing installation that is well-maintained will give your house a an impression of quality, and will also save your energy costs!
Smudging
Double-glazed windows are made up of two separate panes with an air spacer or dense gas in between. This creates an effective seal that stops heat from venting out through the frame. They are a great way to save energy and reduce the carbon footprint of your home. Double glazing may have several issues that can affect its performance and life span. These include condensation, mist and being difficult to open or close.
If you're having difficulty opening your double-glazed windows, it could be due to the weather. It could also be a problem with the hinges or handles. You can ease the problem by wiping down and lubricating the windows with cold water. Contact the company that provided you with the windows as soon as you can get them fixed.
This is another issue that is easily fixable. Again, it's worth checking the warranty to determine what repairs are covered under this.
Fogged or foggy glass can be caused by moisture in the panes. It's typically a sign that the seals are faulty or that your double-glazing unit needs to be replaced. It's a simple fix and you can often get it done without having to replace the entire window, which can save you money.
To fix this problem the technician will drill small holes to vent any moisture that is trapped between the glass and the rest the window. Once the moisture has been removed then a new antifog coating is put on and the window is sealed. Sometimes, the window may require removal however, in the majority of instances, it can be done from within the home.
Mist
Mist can be a huge problem with older double glazing, particularly when it happens on the exterior and the interior of the windows. This is because of a weakening of the seal that is designed to keep air and moisture between the two panes. When making double-glazed units, this seal is created by sealing both panes using an airtight polysulphide or butyl seal around the edges of the glass and the spacer bar. This seal is designed to prevent the window from leaking and provide insulation. It can be difficult to clean double-glazed windows that have mist because you have to break the seal to do so.
The problem with mist is that it lets moisture to enter, which ultimately causes condensation between the panes of glass. The reason for this is that there is a big difference in temperature between the inside and exterior glass's surfaces. The water is then absorbed in the gaps and causes the appearance of a milky white. This can be extremely unsightly and is difficult to remove.
Some companies claim they can repair misting double-glazed windows by drilling holes in the unit and injecting chemicals through the holes, which absorbs moisture from the inside. This isn't a permanent fix and it's easier to replace the entire double-glazed unit.
It is recommended to keep your windows clean and ventilated regularly. It is also recommended to use extractor fans in kitchens and bathrooms and wipe windows with a damp cloth to prevent the accumulation of moisture. If weblink 're not able to avoid the issue completely, we recommend replacing your double-glazed units with A-rated units to increase the efficiency of your energy usage.
