Double Glazed Window Repairs

Double glazing can be a great investment, but frustrating when it doesn't perform. Luckily, the majority of issues are fixable and you do not need to replace your doors or windows.

Double-glazed windows consist of two glass panes separated by a thin gap. This gap is filled with an insulating gas such as the gas argon. This increases a window's thermal efficiency.

Broken panes

While double-pane windows are more resistant to breaking than single-pane glass, they are still able to break or shatter. It is crucial to repair any broken panes in double glazing as soon as possible in order to avoid moisture and energy loss.

Depending on the severity of the crack, you may choose to make a temporary fix or go for an intensive epoxy repair. A temporary repair will aid in preventing further cracking and also keep out cold air and rain. A more extensive repair will strengthen the crack and provide the seal with a stronger one.

To replace a damaged double-pane window, first remove the frame from the sash and place it on a table. Install a grid of duct tap over the pane to prevent any glass fragments from falling off during removal. Once the tape is in place then pull the old double pane glass out of the frame. Next, clean the rabbet and grooves with a wire brush and vacuum or wipe them with a damp cloth. If necessary, remove the wood molding and scrape away all metal or putty prior to installing the replacement pane. Apply a silicone caulk to the rabbet and grooves in order to ensure that the fit is secure.

If you're planning to repair damaged windows yourself, begin by sanding the rabbet until it's smooth and clear of paint or gunk. You can also use a heat gun to soften any glazing points. Once the rabbet has been cleaned, a putty knife can be employed to press putty rope into place. Make sure the putty is uniform in thickness and press against the glass and the frame evenly.

If you're looking for a long-term fix an epoxy repair is a better option over replacing. This method requires more effort and a longer time to wait, but it can be more appealing and will last much longer than a short-term repair.

Condensation





Condensation is a frequent issue for double-glazed windows however, it doesn't mean that they are defective. The fact that your windows show condensation is actually a good indication that your double glazing is doing what it's supposed do, keeping the cold out and the warmth in.

It is actually water vapour from your home that forms a layer on the glass's surface when you observe condensation. It's quite a natural phenomenon and it's not something that's going to cause any damage to your windows unless you allow it sit on the glass for a long time.

Internal condensation is often caused by too much humidity in the room or the low internal temperatures, which causes cold surfaces, like windows, to attract moisture from the air with high dew points (the temperature at which water transforms back into liquid). The steam from kettles, showers and hot pots and cookers can also cause humidity around bathrooms and kitchens.

Do not hang wet clothes close to windows, and make sure your uPVC frames are properly ventilated to prevent the buildup of moisture. To maximize energy efficiency, you should ensure that double-glazed windows are constructed correctly and have the proper gap (6mm). You could also try installing one-way air vents on your windows to increase insulation. If you're still experiencing condensation, there is likely an issue with your seals or gaskets. This is a task best left to professionals.

Draughts

A window that is drafty is an indication that the seal between the glass panes of your double glazing has sprung a leak, and is likely to require replacement. upvc window repairs 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 efficiency of your windows. They can also upgrade your existing frames to incorporate new energy efficient features, like gas filled argon glass units with thermal spacer bars. This reduce heat loss and lower your heating bills.

It is also worth checking the locking mechanisms on your double-glazed windows. Older uPVC window locks are notorious for becoming stiff with time however it's easy to fix this by lubricating them regularly with a specialist uPVC cleaning product.

A professional double glazing company will ensure that the repair is done properly. They'll have the appropriate tools to ensure that your window is sealed and watertight. They can also fix any damage to the frame so that you can enjoy your new double glazing.

Double-glazed windows are tough and long-lasting, but they can experience issues due to weather conditions or wear and wear and tear. If you notice any of these issues, call your local double glazing repair service immediately to get them fixed as soon as possible. You'll be grateful you did it - a double glazing installation well-maintained will give your house a an impression of quality and will save your energy costs!

Smudging

Double-glazed windows consist of two separate panes with a spacer, air or dense gas between them to create an effective seal that stops heating from entering the frame. They're an excellent choice to reduce energy consumption and the carbon footprint of your home. However, double glazing can encounter a myriad of issues that can affect its performance and endurance. This includes condensation, mist and being difficult to open or close.

If you are having trouble opening your double-glazed windows, it could be due to the weather. It could also be a issue with the hinges, or handles. It is possible to solve the issue by wiping down and lubricating the windows with cold water. Contact the company who supplied you with the windows as early as you can to get them fixed.

This is a common issue that is easily fixable. It is also worth checking the warranty to see what, if any, repairs are covered under this.

Foggy and fogged glass can be caused by moisture in the panes. It's usually the result of seals that are not working or an old double-glazing unit that needs 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 save you money.

To fix this problem, a technician will make small holes to release any moisture between the glass and the rest the window. Once the moisture is gone, a new anti-fog coating is applied and the window sealed. Sometimes the window will require removal but, in most instances, it can be done within the home.

Mist

Mist can be a huge problem with older double glazing, particularly when it happens on the exterior and the interior of the windows. This is because of a weakening of the seal designed to block air and moisture between the two panes. This seal is constructed during the manufacturing of double-glazed units by sealing both panes with an airtight polysulphide or butyl seal around the edges and a spacer bar. This is designed to protect the window from heat and prevent the window from being leaking. If you have misted double glazed windows, they can be a challenge to remove and clean, since you'll need to break through the seal in order to clean.

The problem with mist is that it lets moisture in which eventually causes condensation between the glass panes. The reason for this is because there is a significant difference in temperature between the inside and exterior glass surfaces. The moisture gets trapped in the gaps, giving the appearance of milky. This can be quite unsightly and it can be a pain to eliminate.

There are a number of companies who claim they can fix your double glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture from within. However, this is not a permanent solution to the issue and it's much easier to replace the entire double-glazed unit if you are suffering from misting.

The best method to avoid double glazing that is smudgey is by making sure you have adequate ventilation and cleaning your windows regularly. It's also an excellent idea to install extractor fans in bathrooms and kitchens and wipe windows with a damp cloth to prevent the accumulation of moisture. If you are unable to eliminate the problem completely we suggest replacing the double-glazed units you have with A-rated units to increase the efficiency of your energy usage.
