Double Glazed Window Repairs

Double glazing is a great investment for your home, but it can be a pain when it fails to function properly. Most problems can be repaired and you don't have to replace your windows or doors.

Double glazed windows consist of two glass panels separated by an extremely thin gap, filled with insulating gas, such as Krypton or argon. This makes windows more efficient.

Broken panes

Double-paned windows are less likely to break than single panes of glass, however, they may still break or crack. It's important to fix any broken panes in double glazing as soon as possible in order to avoid moisture and energy loss.

You can select an immediate repair or a more extensive epoxy fix based on the extent of your crack. A temporary repair can help prevent further cracking and can protect against the cold and rain. A more extensive repair may reinforce the crack and create an improved seal.

To replace a broken double-pane window, first remove the frame from the sash and place it on the table. Apply a grid of duct tape over the pane to stop glass fragments from falling off during removal. After the tape has been applied, remove the old double-pane glass out of the frame. Then clean the rabbet and grooves using a wire brush and vacuum or wipe them with a damp cloth. If needed, remove the wood molding and scrape away any metal or putty before installing the replacement pane. Apply a silicone caulk over the rabbet and grooves in order to ensure that the fit is secure.

If you're looking to fix damaged windows yourself, start by sanding the rabbet until it's smooth and free of paint or gunk. Heat guns can be used to soften any putty or glazing points. Once the rabbet has been cleaned the putty knife can be used to press the rope of putty into position. Make sure that the putty is of an even thickness and that it presses evenly against the glass frame.

If you're looking for a long-term fix, an epoxy repair is a better choice than a replacement. This option is more costly and requires a longer waiting time, but can be more attractive. It will also last longer than an immediate repair.

Condensation

Condensation is among the most common double glazed window issues, however it doesn't mean that your windows are defective. It's a good thing that your windows are showing signs of condensation. This means that your double glazing is working exactly as it is supposed to, keeping out the cold while allowing the heat.

It is actually water vapour from your home that condenses on the surface of your glass when you notice condensation. It's a natural process and it's not likely to cause damage to your windows unless you let it sit on the surface for a long time.

Internal condensation is usually caused by excessive humidity in the room or by low internal temperatures, which causes cold surfaces like the windows to draw moisture from air with a high dew point (the temperature at which water transforms back into a liquid). The humidity is also a common occurrence in bathrooms and kitchens due to the steam that comes from kettles, showers, and hot pans and pots that are used for cooking.

To prevent condensation, try not to hang wet clothing near your windows and always ensure that your uPVC frames have ample air circulation to stop the accumulation of moisture. You should also ensure that your double-glazed windows are properly insulated and fitted with the correct gap (6mm is ideal) to ensure maximum energy efficiency. You can also install one-way air vents on your windows to improve insulation. If you're still seeing condensation, it's likely the issue is with your gaskets or seals. This is a job best left to an expert.

Draughts

A window that isn't properly sealed can be an indication that the seal between the glass panes has broken and will require to be replaced. This can affect the insulation in your home, and can increase energy bills.

A window repair service will replace the sealed unit for you, while restoring the effectiveness of your windows. They can also upgrade your frames to include new energy saving features, such as gas filled argon glass units that have thermal spacer bars, which will cut down on heat loss and lower your heating bills.

Draughts can also be caused by issues with the locking mechanisms of your double glazed windows It's a good idea to have these checked out. Older uPVC window locks are known for becoming stiff over time however it's easy to fix this by applying regular oiling with an expert uPVC cleaning product.

They'll have the appropriate tools to ensure that your window is completely sealed and watertight. They can also fix any damage to the frame so that you can enjoy your new double glazing.

A double glazing installation well-maintained will give your house a a tangible feeling 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 between them to form an effective seal that prevents heating from entering the frame. They're an excellent option for saving energy and reducing the carbon footprint. Double glazing may have many issues that can affect its performance and life span. These include fog, condensation and difficulty closing 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 mechanism. Wiping them clean with cold water and then lubricating them may help ease the problem, but you should contact the company you bought your windows from as soon as possible to get it repaired.

If your windows or doors have become sagging or dropped over time, this is a common problem that can be easily fixed by a skilled professional. Again, it's worth checking the warranty to see what repairs are covered under this.

Fogged or foggy glass is caused by moisture in the panes. It's usually a sign that your seals aren't working properly or that your double-glazing unit requires to be replaced. RepairMyWindowsAndDoors is a simple fix that can be accomplished without the need to replace the entire window.





To address this issue the technician will drill small holes to vent any moisture that is trapped between the glass and the rest the window. Once the moisture is removed, a new antifog coating is put on and the window is sealed. Sometimes, the window might require removal prior to this happens, but most of the time, it is done from inside the home.

Mist

Mist can be a huge issue with older double glazing, specifically when it happens on the exterior and the interior of the windows. It is caused by an issue with the seal designed to keep moisture and air between the two panes. In the production of double-glazed units, this seal is created by sealing both panes with an airtight butyl or polysulphide seal around the edges of the glass and a spacer bars. This is meant to create insulation and prevent the window from leaks. It can be difficult to clean windows with mist because you have to break the seal to clean them.

The issue with mist is that it lets moisture to enter, which ultimately results in condensation between the panes of glass. This is because there is an enormous temperature difference between the external and internal surfaces of the glass. The moisture is then trapped within the spaces and gives the appearance of a milky white. This can be very unsightly and difficult to get rid of.

There are several companies who claim to be able to repair your double glazed windows that are misting by drilling holes into the unit and injecting chemicals into the holes. Then, they absorb the moisture inside. This is not permanent solution and it's more cost-effective to replace your entire double-glazed unit.

It is best to keep your windows clean and ventilated regularly. It is also a good idea to use extractor fans in bathrooms and kitchens, and wipe down windows with a damp cloth to reduce the accumulation of moisture. If you are unable to avoid the problem, we recommend that you replace your double-glazed windows with new A-rated windows to increase energy efficiency.
