Double Glazed Window Repairs
Double glazing is a great investment for your home, however it can be frustrating when it doesn't work correctly. Fortunately, most issues can be fixed and you don't have to replace your windows or doors.
Double-glazed windows consist of two glass panes that are separated by a small gap. The gap is then filled with an insulating gas such as argon. This helps increase the efficiency of a window's heating.
Broken panes
Double-paned windows are harder to break than single panes of glass, but they can still shatter or crack. If a pane is broken in your double-glazed windows, it's essential to repair it quickly to prevent loss of energy and moisture.
Depending on the degree of the crack, you may choose to use an interim repair or an intensive repair using epoxy. A temporary repair will help to keep cracks from spreading and keep out cold and rain. A more extensive repair can reinforce the crack and create a better seal.
To replace a broken double-pane window, first remove the frame from the sash and set it on a table. Then, place a grid of duct tape to the pane to prevent glass pieces from falling off during removal. Once the tape is secured, pull the old double pane glass out of the frame. Then, use a wirebrush to clean the grooves and rabbets. You can also vacuum them or wipe them clean with a damp cloth. Remove upvc repairs if needed and scrape off any putty or metal glazing points before installing the new pane. Apply a silicone caulk to the grooves and rabbet to ensure a secure fit.
If you're repairing a cracked glass by yourself, start by sanding it until it's smooth and free of paint. You could also use a heat gun to soften any glazing points. After 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 of an even thickness and that it presses evenly against the glass and frame.
If you're looking for the long-term solution you can choose an epoxy repair instead of a replacement. This is more expensive and has a longer waiting period however, it is also more appealing. It will also last longer than an immediate fix.
Condensation
Condensation can be a common issue for double-glazed windows however, it doesn't mean that they are defective. The fact that your windows are showing condensation is actually a good indication that your double glazing is doing what it's supposed to do, keeping cold out and letting the warmth in.
When you see condensation forming on the outside of your window, it is actually water vapor from the inside of your home that has been cooled and condensed on the surface of the glass. It's a natural phenomenon that isn't harmful to your windows unless you leave it on the glass for too long.
The reason for condensation inside is usually a lack of humidity or low temperatures in the room. This creates cold surfaces, like windows, to draw in moisture with a high in dewpoint (the temperature at which water turns into liquid). The steam from showers, kettles, and hot pots and the cooking pans can also cause a lot of humidity around kitchens and bathrooms.
To avoid condensation, try not to hang wet clothing close to your windows. Also, ensure that your uPVC frames have plenty of air circulation to avoid the accumulation of moisture. To ensure maximum energy efficiency, you must ensure that double-glazed windows are installed correctly and insulated with the correct gap (6mm). You can also try installing one-way air vents on your windows to improve insulation. If you're still seeing condensation,, then there's probably a problem with the gaskets or seals and this is something that should be handled by a professional.
Draughts
A draughty double-glazed window is an indication that the seal between the glass panes is broken and will require to be replaced. This could affect the insulation in your home, and can increase the cost of energy.
A window repair service can replace the sealed unit for you, and restore the efficiency of your windows. They can also upgrade your existing frames to include new energy-saving features, like argon gas filled glass units that have thermal spacer bars, which will reduce heat loss and lower your heating costs.
It's also worth checking the locking mechanisms on your double-glazed windows. 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 specialized uPVC cleaner.
A professional double glazing business will ensure that the repair is completed correctly. They'll have the proper tools to ensure that your window is sealed and watertight. They'll also be able fix any other damages to your frame so you can enjoy your gorgeous new double-glazed window with confidence.

You'll be glad you did it - a double glazing installation that's well-repaired will give your home an immediate sense of quality and will save you money on energy bills!
Smudging
Double-glazed windows are made up of two separate panes with an air spacer or dense gas in between. This creates a solid seal that stops heat from getting out of the frame. They are a great method to save energy and decrease your carbon footprint. However, double-glazed windows can have a range of issues that could impact its performance and longevity. These include condensation, fog and being difficult to close or open.
Inability to open your double-glazed windows could be due to the weather, or it could be a problem with the hinges or handles, or the mechanism. Wiping them clean with cold water and lubricating them may help solve the issue, however you must contact the company you bought windows from as soon as possible to have it repaired.
If your doors or windows have dropped or sagged over time, this is another frequent issue that can be fixed by a skilled professional. Also, make sure to check the warranty to determine what, if any, repairs are covered under this.
Fogged or foggy glass is caused by moisture between panes. It's usually a sign that the seals are faulty or that the double-glazing system needs to be replaced. It's a relatively straightforward fix and often you can get it done without having to replace the entire window, which will save you money.
To correct this issue technicians will make tiny holes to vent any moisture between the glass panes and the rest of the window. Once the moisture is gone then a new anti-fog coating is applied and the window will be sealed. Sometimes, the window might require removal prior to this can be accomplished however most of the time it can be done within the home.
Mist
Double glazing that is older may have a mist issue particularly when it occurs both in and out of the window. It is caused by a failure in the seal that is designed to hold air and moisture out between the two panes. During the manufacture of double-glazed units the seal is made by sealing both panes using an airtight butyl or polysulphide seal around the edges of the glass and a spacer bars. This is meant to provide insulation and keep the window from leaks. If you have misted double glazed windows, it may be a challenge to remove and clean, since you'll have to break the hardened seal to clean.
The problem with mist is that it lets moisture to enter, which ultimately results in condensation between the panes of glass. The reason for this is that there is a significant difference in temperature between the interior and exterior glass surfaces. The moisture then gets trapped within the spaces and gives the appearance of a milky white. This can be quite unsightly and is difficult to eliminate.
There are many companies that claim they can fix your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals into the holes which then absorbs the moisture within. This is not permanent solution and it's easier to replace your entire double-glazed unit.
The most effective way to avoid double glazing that is smudgey is by keeping a good level of ventilation and cleaning your windows regularly. Use extractor fans to reduce the buildup of moisture in kitchens and bathrooms. Wipe down windows using a moist cloth to prevent this. If you're unable to completely avoid the issue we suggest replacing the double-glazed units you have with A-rated ones to boost energy efficiency.
