Double Glazed Window Repairs
Double glazing can be a fantastic investment for your home, but it can be frustrating when it fails to function correctly. Most issues can be fixed and you do not have to replace your windows or doors.
Double glazed windows consist of two glass panels that are separated by a very thin gap, which is filled with an insulating gas such as argon or krypton. This helps increase a window's thermal efficiency.
Broken panes
Double-paned windows are harder to break than single panes of glass, but they can still shatter or crack. If a pane breaks in your double glazing, it's important to repair it immediately to avoid water and energy loss.
Depending on the extent of the crack you can choose to use an immediate fix or go for an intensive repair using epoxy. A temporary repair can help keep cracks from spreading and keep out cold and rain. A more extensive repair will strengthen the crack and will provide the seal with a stronger one.
To replace a broken double-pane window, remove the frame and place it on an un-slip surface. Then, apply a grid of duct tape on the pane to keep any glass pieces from falling off during removal. Once the tape has been applied, remove the double-pane glass that was previously in the frame. Then clean the rabbet and grooves using a wire brush, vacuum or wipe with a damp cloth. Remove the wood moldings if necessary and scrape off any metal glazing points before installing the new pane. Apply silicone caulk to the rabbets and grooves in order to ensure a tight fit.
If you're fixing a damaged glass by yourself, start by sanding it until it's smooth and free of paint. The use of heat guns is to soften any putty or glazing. Once the rabbet has been cleaned and sanitized, a putty knife may be used to push the rope of putty into position. Make sure that the putty is a uniform thickness and press against the glass and frame evenly.
If you prefer a long-term fix the repair of an epoxy is a better choice over replacing it. This option is more costly and has a longer waiting period however, it is also more appealing. It will also last longer than the temporary fix.
Condensation
Condensation is among the most common double glazed window problems, but it doesn't necessarily mean your windows aren't working properly. It's a good thing your windows show condensation. This indicates that double glazing is working as it is supposed to, keeping out the cold and keeping in the warmth.
It's actually water vapour from your home that forms a layer on the surface of your glass when you notice condensation. It's a natural phenomenon that isn't harmful to your windows unless you leave it on the surface long enough.
upvc repair for internal condensation is usually excessive humidity or low temperatures in the room. This results in cold surfaces, such as windows, to attract moisture that is high in dewpoint (the temperature where water turns into liquid). The steam from kettles, showers and hot pots as well as cookers can also cause humidity around bathrooms and kitchens.
Avoid hanging wet clothing close to windows, and make sure your uPVC frames are properly ventilated to avoid moisture buildup. You should also ensure that your double-glazed windows are correctly insulated and installed with the proper gap (6mm is best) to maximize energy efficiency. You could also try installing one-way air vents on your windows to improve insulation. If you're still seeing condensation,, then there's a problem with the seals or gaskets and this is a job for a professional.
Draughts
A double-glazed window that is draughty is an indication that the seal between the glass panes has broken and needs to be replaced. This will affect the insulation of your home and cause an increase in your energy bills and therefore it is important to act quickly when you spot this issue.
A window repair service can replace the sealed unit for you, restoring the effectiveness of your windows. They can also upgrade your frames to incorporate new energy saving features, like argon gas filled glass units that have thermal spacer bars that will cut down on the loss of heat and reduce the cost of heating.
Draughts can be caused by problems with the locking mechanisms of double-glazed windows, so it's worth getting the windows checked. It is common for older uPVC window lock mechanisms to become stiff with the passage of time. This can be easily fixed by lubricating your locks regularly using a specialist uPVC cleaner.
A professional double glazing company will ensure that the repair is completed correctly. They'll have the appropriate tools to make sure that your window is completely resealed and watertight. They can also repair any damage to the frame so that you can enjoy your new double-glazed window.
Double glazed windows are long-lasting and durable, however they may develop issues as a result of wear and tear or weather. If you notice any of these issues contact your local double glazing repair service immediately to get them fixed in the shortest time possible. You'll be glad you did. A properly repaired double glazing installation will give your house that tangible sense of quality, and it will also save you money on your energy bills!
Smudging
Double-glazed windows consist of two separate panes with an air spacer or dense gas in between. This creates a strong seal to stop heat from escaping through the frame. They're an excellent choice to reduce energy consumption and the carbon footprint of your home. However, double-glazed windows can experience a variety of issues that may affect its performance and endurance. This includes condensation, mist, and difficult to open or close.
If you're having trouble opening your double-glazed windows it could be because of the weather. It could also be due to a issue with the hinges or handles. You can solve the issue by lubricating and wiping down the windows with cold water. Contact the company who sold you the windows as early as you can to have them fixed.
This is another issue which can be easily fixed. It is also worth checking the warranty to see what, if any, repairs are covered under this.
Foggy and fogged glass can be caused by moisture between the panes. It's typically the result of seals that are not working or an old double-glazing unit that needs replacing. It's a relatively straightforward fix and you'll often complete the task without the need to replace the entire window, which can save you money.
To resolve this issue the technician will make small holes to release any moisture that is trapped between the glass and the rest the window. After the moisture has gone then a new anti-fog coating will be applied and the window sealed. Sometimes, windows need to be removed but, in most instances, it is done within the home.
Mist
Mist can be a huge problem with older double glazing, particularly when it happens on the outside and inside of the windows. It is due to a failure in the seal designed to keep air and moisture out between the two panes. The seal is made during the production of double-glazed units by sealing both panes with an airtight polysulphide seal or butyl seal around the edges and spacer bar. This seal is designed to prevent the window from leaking and provide insulation. It can be difficult to clean windows with mist because you have to break the seal to do this.
The issue with mists is that they allow moisture to enter and cause condensation between the glass panes. This is due to a large difference in temperature between the external and internal surfaces of the glass. The moisture then gets trapped in the gaps and causes an appearance of milky white. This can be extremely unsightly and difficult to remove.
There are many companies who claim to be able to repair your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture within. This isn't permanent solution and it's more cost-effective to replace the entire double-glazed unit.
The most effective method to avoid misty double glazing is keeping a good level of ventilation and cleaning your windows regularly. It's also an excellent idea to install extractor fans in bathrooms and kitchens, and wipe down windows with a damp cloth to prevent the accumulation of moisture. If you're not able to eliminate the problem completely we suggest replacing the double-glazed units you have with A-rated ones to boost energy efficiency.
