Double Glazed Window Repairs
Double glazing is a great investment for your home, however it can be a pain when it doesn't work correctly. Most issues can be addressed and you don't need to replace doors or windows.
Double glazed windows consist of two glass panels separated by a thin gap, which is filled with an insulating gas such as Krypton or argon. This improves the efficiency of windows.
Broken panes
Double-paned windows are more difficult to break than single panes of glass however they are still susceptible to shattering or break. It's important to fix the broken pane of double glazing as quickly as possible in order to avoid moisture and energy loss.
You can opt for a temporary repair or a more intensive epoxy fix depending on the severity of your crack. A temporary repair can aid in preventing further cracks, and also keep out cold air and rain. A more extensive repair will strengthen the crack, and will provide an even stronger seal.
To replace a damaged double-pane windows, first remove the frame from the sash and set it on the table. Install a grid of duct tape over the pane in order to stop glass fragments from falling off during removal. Once the tape has been removed, take the old double-pane glass out of the frame. Then, use a wirebrush to clean the rabbets and grooves. You can also vacuum them or wipe them with a damp cloth. If necessary, remove the wood molding and scrape off all metal or putty before installing the replacement pane. Finally, apply a silicone caulk to the grooves and rabbet to ensure an ideal fit.
If you're repairing a cracked glass by yourself, start by sanding it until it's smooth and free of paint. You can also use a heat gun to soften any glazing points. Once the rabbet has been cleaned then you can use a putty blade to force a rope into place. Make sure that the putty has an even thickness, and that it presses evenly against the glass frame.
If you're looking for a long-term solution then you could opt for an epoxy repair instead of a replacement. This method requires more effort and a longer time to wait but it's more appealing and last longer than a temporary repair.
Condensation
Condensation is one of the most frequently encountered double-glazed window issues, but it doesn't necessarily mean your windows are defective. The fact that your windows show condensation is actually a good sign because it means that your double glazing is doing what it's supposed to do, keeping cold out and letting the warmth in.
If you notice condensation appearing on the outside of your window, it is actually water vapor from inside of your home that has been cooled and condensed on the glass's surface. It's a natural phenomenon that won't cause harm to your windows in the event that you don't leave it on the surface too long.
The cause of internal condensation is usually excessive humidity or low temperatures in the room. This causes cold surfaces, like windows and doors, to attract moisture that is high in dewpoint (the temperature at which water turns into liquid). It is also commonplace in bathrooms and kitchens due to the steam that comes from kettles, showers, and hot pots and pans that are used for cooking.
To prevent condensation, try not to hang wet clothes close to your windows. Also, make sure that your uPVC frames have plenty of air circulation to prevent the build-up of moisture. To ensure maximum energy efficiency, be sure that your double-glazed windows have been installed correctly and insulated with the correct gap (6mm). You could also consider adding one-way air vents to your windows to further improve insulation. If you still get condensation, there is likely the issue is with your seals or gaskets. This is a task that should be left to professionals.
Draughts
A window that is drafty is an indication that the seal between the glass panes of your double glazing has started to leak and is likely to require replacement. This can affect the insulation of your home and could result in an increase in your energy bills and therefore it is important to act as soon as you notice this issue.
Window repair services can replace your sealed unit, restoring the efficiency to your windows. They can also modify your existing frames to incorporate new energy saving features, like argon gas filled glass units that have thermal spacer bars that will reduce heat loss and lower your heating costs.
It's also worth checking the locking mechanisms of your double-glazed windows. Older uPVC window locks are infamous for becoming stiff over time however, it's simple to fix this issue by regular lubrication using an expert uPVC cleaning product.
A reputable double glazing company can ensure that your repair is done correctly. They'll have the appropriate tools to make sure that your window is completely resealed and watertight. They can also fix any damage to the frame so that you can enjoy your new double glazing.
Double-glazed windows are tough and long-lasting, but they may develop problems because of weather or wear and wear and tear. Contact your local double-glazing repair service as soon as you spot any of these issues. You'll be thankful that you did. A well-maintained double glazing installation will give your home that tangible feeling of quality and will also save you money on your energy bills!
Smudging
Double-glazed windows are comprised of two separate panes with a spacer or dense gas between. This creates an effective seal to prevent heat from escaping through the frame. They are a great way to save energy and reduce the carbon footprint of your home. However, double glazing may experience a variety of issues that could impact its performance and durability. These include condensation, fog and being difficult to close or open.
The difficulty in opening your double-glazed windows could be due to the weather or it might be a fault with the hinges or handles, or the mechanism. Wiping them down with cold water and lubricating them may help alleviate the issue, but you should contact the manufacturer that you purchased your windows from as soon as you can to get it repaired.
This is another common problem that can be fixed easily. Also, make sure to check the warranty to determine what repairs are covered under this warranty.
Fogged or foggy glass could be caused by moisture between the panes and is usually a sign of faulty seals or a double-glazing unit that requires replacement. It's a relatively straightforward fix and you can often complete the task without having to replace the entire window, which can reduce the cost of replacement.
To address this issue technicians will drill tiny holes to vent out any moisture between the glass panes and other parts of the window. When the moisture is gone, a new anti-fog coating will be applied and the window will be sealed. Sometimes, the window may need to be removed but, in most cases, it can be done from within the home.

Mist
Mist can be a big issue for older double glazing, specifically when it occurs on both the outside and inside of the windows. This is because of a weakening of the seal that is designed to keep air and moisture between the two panes. In the production of double-glazed units this seal is created by sealing both panes with an airtight polysulphide or butyl seal around the edges of the glass and spacer bars. This is meant to protect the window from heat and prevent the window from leaks. It isn't easy to clean misted double-glazed windows because you have to break the seal in order to clean them.
https://www.repairmywindowsanddoors.co.uk/ewell-windowrepair/ with mist is that it lets moisture to enter, which ultimately causes condensation between the glass panes. This is because there is a large difference in temperature between the external and internal surfaces of the glass. The moisture is then trapped in the spaces and creates a milky white appearance. It can be very unsightly and it can be a pain to eliminate.
Some companies claim they can repair misting double-glazed windows through drilling holes in the unit and injecting a chemical through the holes, which absorbs moisture from the inside. However, this is not an end-to-end solution and it is far easier to replace the whole double-glazed unit in the event that you are experiencing misting.
It is best to keep your windows clean and conditioned regularly. It is also an excellent idea to install extractor fans in bathrooms and kitchens and wipe windows with a damp cloth to prevent the build-up of moisture. If you are unable to avoid the issue completely we suggest replacing the double-glazed units you have with A-rated units to increase the efficiency of your energy usage.
