Double Glazed Window Repairs
Double glazing is a great investment, but frustrating when it fails to work. Luckily, most problems can be fixed and you don't have to replace your windows or doors.
Double glazed windows consist of two glass panels separated by a very thin gap that is filled with insulating gas, such as argon or krypton. This improves the efficiency of a window's heating.
Broken panes
Double-paned windows are less likely 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 quickly to prevent loss of energy and moisture.
Depending on the extent of the crack you may choose to fix it with an immediate fix or opt for more extensive epoxy repair. A temporary repair will help to prevent further cracking and keep out rain and cold air. A more extensive repair can make the crack stronger and provide a better seal.
To replace a broken double-pane window, first take the frame from the sash and place it on the table. Then, place a grid of duct tape over the pane to stop glass pieces from falling off during removal. Once the tape is secured, pull the old double pane glass off of the frame. Then clean the grooves and rabbet with a wire brush and vacuum or wipe with a damp cloth. Remove the wood moldings if necessary and scrape away all metal glazing points prior to installing the new pane. Apply silicone caulk to the grooves and rabbets to ensure a tight fit.
If you're trying to repair a damaged glass yourself, start by sanding it until it's smooth and free of paint. Heat guns can be used to soften any glazing or putty points. After the rabbet has been cleaned and sanitized, a putty knife may be used to press a rope of putty into place. Make sure the putty has an even thickness and is pressed against the glass and frame evenly.
If you prefer a long-term fix an epoxy repair is a better choice over replacing it. This option is more costly and will require a longer wait time however it can be more appealing. It will also last longer than the temporary fix.
Condensation
Condensation is a typical issue for double-glazed windows but that doesn't mean they're defective. The fact that your windows show condensation is actually a positive indicator that your double glazing is doing what it's supposed to keep the cold out and the warmth in.
If you notice condensation appearing on the outside of your window, it is actually water vapor coming from the inside of your home that has been cooled and condensed on the surface of the glass. It's a natural process and it's not something that's likely to cause any damage to your windows unless you let it remain on the glass for too long.
Internal condensation is often caused by too much humidity in the room or by low internal temperatures, which causes cold surfaces like the windows to draw moisture from air that has a high dew point (the temperature at which water changes into liquid). Humidity is also inevitable around kitchens and bathrooms because of steam from showers or kettles as well as hot pots and pans that are used for cooking.
Do not hang wet clothes close to windows and ensure that your uPVC frames are ventilated to avoid moisture buildup. Also, make sure that your double-glazed windows are properly insulated and fitted, with the proper gap (6mm is best) to ensure maximum energy efficiency. You could also consider installing one-way air vents on your windows to further improve insulation. If you're still seeing condensation,, then there's probably problems with gaskets or seals and this is a job for a professional.
Draughts
A double-glazed window that is draughty is an indication that the seal between your glass panes is broken and will need to be replaced. This can affect the insulation of your home and can cause an increase in energy bills which is why it's crucial to act as soon as you notice the problem.

They can also upgrade your existing frames to incorporate new energy efficient features, like gas filled argon glass units that have thermal spacer bars. This will reduce the loss of heat and reduce your heating costs.
Draughts can also be caused by issues with the locking mechanisms of double-glazed windows It's a good idea to have these checked out. Older uPVC window locks are known for becoming stiff over time, but it's easy to fix this issue by applying regular oiling with a specialized uPVC cleaning product.

Smudging
Double-glazed windows are comprised of two separate panes, with the spacer or gas between. This creates an effective seal that stops heat from getting out of the frame. They're an excellent choice for saving energy and reducing the carbon footprint. Double glazing can have a number of problems that can impact its performance and life span. These include condensation, mist and being difficult to open or close.
Difficulty opening your double glazed windows could be due to the weather, or it could be due to a problem with the hinges or handles, or the mechanism. It is possible to solve the issue by lubricating and wiping the windows with cold water. Contact the company who supplied you with the windows as soon as you can to get them fixed.
If your windows or doors have sagged or dropped over time, this is another common issue which can be easily solved by a trained professional. It is always worth checking your warranty to see whether there are any repairs covered.
Fogged and foggy glass can be caused by moisture in the panes and is usually the result of seals that are not working or an old double-glazing unit that needs replacing. This is a simple fix that can be done without having to replace the entire window.
To fix this problem technicians will make small holes to release any moisture that is trapped between the glass and the rest the window. Once the moisture is removed, a new antifog coating is applied and the window is sealed. Sometimes, the window might need to be removed prior to this can be accomplished however the majority of the time, it is done within the home.
Mist
Double glazing that is older may be prone to mist, especially when it occurs both in and out of the window. It is caused by an issue with the seal designed to prevent air and moisture out between the two panes. In the production of double-glazed units the seal is made by sealing both panes using an airtight polysulphide or butyl seal around the edges of the glass as well as a spacer bar. This seal is designed to prevent the window from leaking and provide insulation. If you have misted double-glazed windows, it may be a challenge to remove and clean, since you'll have to break through the seal in order to clean.
https://www.repairmywindowsanddoors.co.uk/loughton-windowrepair/ with mists is that they allow moisture to enter which causes condensation between the glass panes. This is due to an enormous temperature difference between the internal and external surfaces of the glass. The moisture then gets trapped in the spaces and creates a milky white appearance. This can be very unsightly and is difficult to get rid of.
There are a number of companies that claim that they can fix your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture from within. However, this isn't an end-to-end solution to the issue and it's much easier to replace the entire double-glazed unit in the event that you are suffering from misting.
It is important to keep your windows clean and well-ventilated regularly. It is also recommended to use extractor fans in bathrooms and kitchens and clean windows with a damp cloth to reduce the accumulation of moisture. If you are unable to completely avoid the issue, we recommend replacing the double-glazed units you have with A-rated ones to improve energy efficiency.
