Double Glazed Window Repairs
Double glazing is an investment that is worth it, but can be frustrating when it doesn't perform. Luckily, the majority of issues are repairable and you don't have to replace your doors or windows.
Double-glazed windows comprise two glass panels separated by a thin gap that is filled with insulating gas, such as Krypton or argon. This increases the thermal efficiency of windows.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they can still crack or shatter. It is important to repair any broken panes in double glazing as soon as you can to prevent moisture and energy loss.
You can choose an immediate repair or a more intensive epoxy fix depending on the extent of your crack. A temporary repair can help prevent further cracking and keep out rain and cold air. A more extensive repair will strengthen the crack, and will provide an even stronger seal.
To replace a double-pane broken window, take the frame off and place it on a flat surface. Apply a grid of duct tape over the pane in order to prevent any glass fragments from falling off during removal. After the tape has been removed, take the old double-pane glass out of the frame. Then clean the rabbet and grooves with a wire brush and vacuum or wipe them with a damp cloth. Remove the wood molding, if required and scrape off any metal glazing points prior to installing the new pane. Then, apply a silicone caulk to the rabbet and grooves to ensure an ideal fit.
If you're trying to repair a damaged glass by yourself, start by sanding the glass until it's smooth and free of paint. Heating guns can be used to soften any glazing or putty points. Once the rabbet has been cleaned then you can use a putty blade to force ropes into place. Make sure that the putty is of an even thickness and that it presses equally against the glass and frame.
If you're looking for a longer-term fix the repair of an epoxy is a better choice than a replacement. This is more expensive and will require a longer wait time however, it is also more appealing. It also lasts longer than an immediate fix.
Condensation
Condensation is among the most frequently encountered double-glazed window problems, but it doesn't mean that your windows aren't working properly. 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 keep the cold out and the warmth in.
It is actually water vapour from your home that forms a layer on the surface of your glass when you observe condensation. It's a normal phenomenon and it's not something that's likely to cause any harm to your windows unless you let it sit on the glass for too long.
Internal condensation is usually caused by high humidity in the room or the low internal temperatures, which causes cold surfaces like the windows to draw moisture from air with high dew points (the temperature at which water transforms back into liquid). Humidity is also inevitable around kitchens and bathrooms due to the steam that comes from kettles, showers, as well as hot pots and pans that are used for cooking.
Avoid hanging wet clothes close to windows and ensure that your uPVC frames are ventilated to prevent the buildup of moisture. Also, ensure that your double glazed windows are properly insulated and fitted with the right gap (6mm is best) for optimum energy efficiency. You could also try adding one-way air vents to your windows to increase insulation. If you're still seeing condensation, there is likely a problem with your gaskets or seals. This is a task best left to a professional.
Draughts
A double-glazed window that is draughty is an indication that the seal between the glass panes has failed and will need to be replaced. This can affect the insulation of your home and result in an increase in your energy bills, so it's important to act quickly when you spot this problem.
Window repair services can replace your sealed unit, restoring efficiency to your windows. They can also upgrade existing frames with new energy-saving features, like glass units that are filled with argon, as well as thermal spacer bars to reduce heat loss and cut down on heating costs.
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. Older uPVC window locks are notorious for becoming stiff after a while however it's easy to fix this issue by applying regular oiling with an expert uPVC cleaning product.

Smudging
Double-glazed windows are made up of two separate panes with an air spacer or dense gas between. This creates an effective seal to stop heat from venting out through the frame. They are a great way to conserve energy and reduce your carbon footprint. However, double-glazed windows can have a range of issues that could impact its performance and longevity. These include fog, condensation and difficulties to close or open.
If you're having difficulty opening your double-glazed windows it could be because of the weather. It could also be a issue with the hinges or handles. It is possible to solve the issue by lubricating and wiping down the windows with cold water. Contact the company who provided you with windows as early as you can to have them fixed.
If your windows or doors have sagged or dropped over time, this is another frequent issue that can be easily fixed by an experienced professional. It is a good idea to check your warranty to see whether any repairs are covered.
Foggy or fogged glass is caused by moisture between panes. It's typically a sign that the seals aren't working properly or that your double-glazing unit needs to be replaced. It's a simple fix and often you can complete the task without the need to replace the entire window, which can save you money.
To fix this issue A technician will make tiny holes to vent out any moisture between the glass panes and the rest of the window. After the moisture has been removed then a new antifog coating is put on and the window is sealed. Sometimes, the window might require removal prior to this can happen but most of the time it is done within the home.
Mist
Mist can be a big issue for older double glazing, specifically when it occurs on both the exterior and the interior of the windows. It is due to an issue with the seal that is designed to hold air and moisture between the two panes. In the production of double-glazed units, this seal is created by sealing both panes using an airtight polysulphide or butyl seal around the edges of the glass as well as a spacer bars. This seal is designed to keep the window from leaking, and also provide insulation. If you have misted double-glazed windows, they can be difficult to take off and clean, since you'll have to break the hardened seal in order to clean.
The problem with mists is that they permit moisture to get in which 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 within the spaces and gives an appearance of milky white. This can be extremely unsightly and difficult to remove.
Some firms claim to be able to repair misting double-glazed windows by drilling holes into the unit and injecting chemicals through the holes, which absorbs moisture from the inside. This is not permanent solution and it's more cost-effective to replace your entire double-glazed unit.
The best way to prevent misty double glazing is keeping a good level of ventilation and cleaning your windows regularly. Utilize extractor fans to lessen moisture buildup in bathrooms and kitchens. Wipe down windows using a moist cloth to prevent this. If you're not able to avoid the issue completely, we recommend replacing your double-glazed units with A-rated ones to boost energy efficiency.
