Double Glazed Window Repairs
Double glazing is an excellent investment for your home, but it can be frustrating when it doesn't work properly. 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. This gap is filled with an insulating gas, like argon. This improves the thermal efficiency of windows.
Broken panes
Double-paned windows are more difficult to break than single panes of glass, however they are still susceptible to shattering or crack. If a pane breaks in your double glazing, it's important to fix it as soon as possible to prevent loss of energy and moisture.
Depending on the degree of the crack, you may decide to use an interim fix or go for a more intensive repair using epoxy. A temporary repair can aid in preventing further cracks, and keep out rain and cold air. A more extensive repair could strengthen the crack and provide a better seal.
To replace a broken double-pane window, first remove the frame from the sash, and then set it on a table. Install a grid of duct tap over the pane in order to prevent any glass fragments from falling off during removal. After the tape is installed, remove the double-pane glass that was previously in the frame. Next, clean the grooves and rabbet with a wire brush and vacuum or wipe them with a damp cloth. Remove the wood moldings if necessary and scrape off any metal glazing points or putty before installing the new pane. Apply a silicone caulk over the grooves and rabbet to ensure a secure fit.
If you're trying to repair a damaged glass by yourself, begin by sanding it until it's smooth and free of paint. Heat guns can be used to soften any putty or glazing. Once the rabbet is cleaned the putty knife can be used to push putty rope into position. Make sure the putty is uniform in thickness and press against the glass and the frame evenly.
If you are looking for the long-term solution then you could opt for an epoxy repair instead of replacing. This option requires more work and a longer time to wait however it is more appealing and will last longer than a short-term repair.
Condensation
Condensation is among the most frequently encountered double-glazed window issues, however it doesn't mean that your windows are defective. It's good to know that your windows display condensation. This means that double glazing is working as it should, keeping out the cold and retaining the heat.
When you notice condensation developing on the outside of your windows, it is actually water vapor from the inside of your home that has cooled down and condensed on the glass's surface. It's a natural process that isn't harmful to your windows, except if you let it sit on the surface long enough.
The reason for condensation inside is usually too much humidity or low temperatures in the room. This creates cold surfaces, such as windows and doors, to attract moisture that is high dewpoint (the temperature at which water turns 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.
Avoid hanging wet clothing close to windows, and make sure your uPVC frames are well ventilated to avoid moisture buildup. You should also ensure that your double-glazed windows are correctly insulated and installed with the right gap (6mm is the ideal) for optimum energy efficiency. You can also add one-way air vents to your windows to improve insulation. If you're still getting condensation, however, then there's likely problems with the gaskets or seals and this is definitely a job for an expert.
Draughts
A window that is drafty is a sign that the seal between the glass panes of your double glazing has sprung a leak and is likely to need replacing. This could affect the insulation in your home and also increase the cost of energy.

Smudging
Double-glazed windows are made up of two separate panes with the spacer or gas between. This creates a strong seal to prevent heat from getting out of the frame. They're an excellent choice to reduce energy consumption and your carbon footprint. However, double glazing may experience a variety of issues that may affect its performance and endurance. These include fog, condensation and being difficult 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 due to a issue with the hinges or handles. Wiping them clean with cold water and then lubricating them can ease the problem, but you should contact the manufacturer that you purchased windows from as quickly as possible to have it fixed.
This is another common problem that is easily fixable. It is also worth checking the warranty to see what, if any, repairs are covered under this warranty.
Fogged or foggy glass can be caused by the presence of moisture between the panes. It's usually a sign that your seals are faulty or that your double-glazing unit requires to be replaced. It's a fairly simple fix and you'll often complete the task without the need to replace the entire window, which will reduce the cost of replacement.
To address this issue the technician will make small holes to let out any moisture that is trapped between the glass and the rest the window. Once the moisture has been removed then a new antifog coating is applied and the window is sealed. Sometimes, the window may require removal but, in most instances, it can be done from within the home.
Mist
Double glazing that is older may be prone to mist particularly if it occurs both inside and outside the window. It is caused by an issue with 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 polysulphide or butyl seal around the edges of the glass as well as a spacer bars. This is designed to protect the window from heat and prevent the window from being leaking. It can be difficult to clean misted double-glazed windows as you must break the seal in order to do so.
The problem with mist is that it allows moisture to enter, which ultimately results in condensation between the panes of glass. This is because there is a large difference in temperature between the internal and external surfaces of the glass. The moisture is trapped in the gaps, giving an appearance of milky. This can be extremely unsightly and is difficult to remove.
Some companies claim they can repair misting double-glazed windows through drilling holes in the unit and injecting a chemical through the holes that absorbs moisture from the inside. It's not a permanent fix and it's more cost-effective to replace your entire double-glazed unit.
It is best 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 an damp cloth to minimize the accumulation of moisture. If you are unable to avoid the problem, we recommend that you replace windows that are double-glazed with A-rated windows to increase energy efficiency.
