Double Glazed Window Repairs Double glazing is a great investment, but frustrating when it fails to work. Luckily, most problems are repairable and you don't need to replace your doors or windows. Double-glazed windows are made up of two glass panes separated by a very thin gap. The gap is then filled with an insulating gas like the gas argon. This increases a window's efficiency. Broken panes Double-paned windows are harder to break than single panes of glass however they are still susceptible to shattering or break. It is important to repair the broken pane of double glazing as soon as you can to prevent moisture and energy loss. Depending on the extent of the crack you may choose to make an interim fix or go for more extensive repair using epoxy. A temporary repair can aid in preventing further cracking and will keep out rain and cold air. A more extensive repair could make the crack stronger and provide more secure seal. To replace a double-pane damaged window, remove the frame and place it on a flat surface. Apply a grid of duct tap over the pane in order to prevent any glass fragments from falling during removal. After the tape has been removed, take the old double-pane glass out of the frame. Then, clean the grooves and rabbet using a wire brush, vacuum or wipe them with a damp cloth. If needed, remove the wood molding and scrape away all putty or metal points before putting in the replacement pane. Apply silicone caulk in the rabbets and grooves in order to ensure a snug fit. If you're planning to repair damaged windows yourself, begin by sanding the rabbet until it's smooth and clear of paint or gunk. Heat guns can be used to soften any putty or glazing points. Once the rabbet has been cleaned, you can use a putty knife to push ropes into place. Make sure the putty is a uniform thickness and presses against the glass and frame evenly. If you're looking for a longer-term fix, an epoxy repair is a better choice than replacing. This is more expensive and will require a longer wait time however, it is also more appealing. It also lasts longer than the temporary repair. Condensation Condensation is one of 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 display condensation. This means that double glazing is working just as it is supposed to, keeping out the cold and keeping in the heat. Repair My Windows And Doors is actually water vapour from your home which condenses on the surface of your glass when you notice condensation. It's quite a natural phenomenon and it's not something that's likely to cause any damage to your windows unless you let it sit on the surface for too long. Internal condensation is usually caused by too much humidity in the room or the low internal temperatures, causing cold surfaces, like windows, to draw moisture from air that has a high dew point (the temperature at which water transforms back into a liquid). The humidity is also a common occurrence in kitchens and bathrooms because of the steam that comes from kettles, showers, as well as hot pots and pans used during cooking. To avoid condensation, try not to hang wet clothes close to your windows. Also, make sure that your uPVC frames have plenty of air circulation to prevent the build-up of moisture. To maximize energy efficiency, also make sure that double-glazed windows are properly installed and insulated with the correct gap (6mm). You can also try adding air vents that are one-way to your windows to further improve insulation. If you're still experiencing condensation, there's probably a problem with gaskets or seals and this is definitely something that should be handled by a professional. Draughts A window that is drafty is an indication that the seal between the glass panes of your double glazing has started to leak, and is likely to need replacing.

A window repair service will replace the sealed unit for you, and restore the effectiveness of your windows. They can also upgrade your existing frames with new energy-efficient features, including argon-filled glass units and thermal spacer bars that will reduce heat loss, and lower your heating costs. It is also worth checking the locking mechanisms of your double-glazed windows. It's normal for older uPVC window lock mechanisms to become stiff as they age. This is easily fixed by regularly lubricating the locks using a specialist uPVC cleaner. A professional double glazing company can ensure that your repair is done properly.

Smudging Double-glazed windows are comprised of two separate panes, with an air spacer or dense gas in between. This creates a strong seal that stops heat from getting out of the frame. They are a great way to save energy and reduce your carbon footprint. However, double glazing can have a range of issues that could impact its performance and longevity. This includes condensation, mist, and difficult to open or close. Inability to open your double-glazed windows could be due to the weather, or it could be due to a problem with the hinges, handles or mechanism. Wiping them down with cold water and lubricating them can help to alleviate the issue, but you should contact the manufacturer you bought windows from as quickly as you can to get it repaired. If your windows or doors have become sagging or dropped over time, this is a common issue that can be easily fixed by an experienced professional.

It's a relatively straightforward fix and you can often complete the task without having to replace the entire window, which can save you money. To resolve this issue technicians will make small holes to let out any moisture between the glass and the window. When the moisture is gone, a new anti-fog coating is applied and the window will be sealed. Sometimes, the window will need to be removed prior to this can be accomplished but most of the time, it can be done from inside the home. Mist Double glazing that is older may have a mist issue in particular if it occurs both in and out of the window. It is caused by a failure in the seal designed to keep moisture and air between the two panes. During the manufacture 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 as well as a spacer bar. This is intended to protect the window from heat and prevent the window from leaking. If you have misted double glazed windows it can be difficult to take off and clean, as you will need to break the hardened seal in order to clean. The issue with mists is that they permit moisture to enter, which leads to condensation between the glass panes. This is due to huge differences in temperature between the external and internal surfaces of the glass. The water is then absorbed in the gaps and causes a milky white appearance. This can be very unattractive and difficult to remove. Some firms claim to be able to repair misting double-glazed windows by drilling holes into the unit and injecting a chemical through the holes that absorbs moisture from the inside. It's not an end-to-end solution and it's more cost-effective to replace your entire double-glazed unit. It is recommended to keep your windows clean and well-ventilated regularly. It is also recommended to use extractor fans in bathrooms and kitchens, and wipe down windows with an damp cloth to minimize the build-up of moisture. If you're unable to avoid the issue completely we suggest replacing your double-glazed units with new A-rated units to increase the efficiency of your energy usage.
