A Productive Rant About Double Glazed Window Repair
Double Glazed Window Repairs

Double glazing can be an investment that is worth it, but can be frustrating when it doesn't work. Fortunately, most issues are repairable and you don't have to replace your doors or windows.

Double-glazed windows are made up of two glass panels that are separated by an extremely thin gap, filled with insulating gas, such as Krypton or argon. This increases a window's efficiency.

Broken panes

Double-paned windows are harder to break than single panes of glass, however, they may still break or crack. It's important to fix a broken pane in double glazing as quickly as you can to prevent loss of energy and moisture.

You can choose an immediate repair or a more extensive epoxy fix based on the degree of the crack. A temporary repair will help prevent further cracking, and will keep out cold air and rain. A more extensive repair will strengthen the crack and will provide a stronger seal.

To replace a damaged double-pane window, first remove the frame from the sash, and then set it on the table. Apply a grid of duct tap over the pane in order to prevent any glass fragments from falling off during removal. Once the tape has been applied, remove the double-pane glass that was previously in the frame. Then, clean the grooves and rabbet using a wire brush, vacuum or wipe them with a damp cloth. Remove the wood molding, if required and scrape off any metal glazing points prior to putting in the new pane. Then, apply a silicone caulk to the rabbet and grooves in order to ensure an ideal fit.

If you're repairing a cracked glass yourself, start by sanding the glass until it's smooth and free of paint. You could also use a heat gun to soften any glazing or putty points. Once the rabbet is cleaned, a putty knife can be used to push the rope of putty into place. Make sure upvc repair is a uniform thickness and presses against the glass and the frame evenly.

If you're looking for a long-term fix an epoxy repair is a better option over a replacement. This option is more expensive and will require a longer wait time, but can be more appealing. It also lasts longer than an immediate fix.

Condensation

Condensation is a frequent issue for double-glazed windows however, it doesn't mean that they're not functioning properly. The fact that your windows show condensation is actually a positive sign because it means that your double glazing is doing what it's supposed keep the cold out and letting warmth in.

When you notice condensation developing on the outside of your window, it is actually water vapor from the inside of your home that has been cooled and condensed onto the glass's surface. It's a natural phenomenon that won't cause harm to your windows, unless you leave it on the glass for too long.

The reason for condensation inside is usually excessive humidity or low temperatures in the room. This causes cold surfaces, like windows and doors, to draw in moisture that is high in dewpoint (the temperature at which water turns into a liquid). The steam from showers, kettles and hot pots as well as cookers can also cause humidity around kitchens and bathrooms.

To avoid condensation, make sure not to hang wet clothes near your windows and always ensure that your uPVC frames are able to provide ample air circulation to avoid the build-up of moisture. For maximum energy efficiency, you must also make sure that your double-glazed windows are properly installed and insulated with the proper gap (6mm). You can also install one-way air vents to your windows to improve insulation. If you're still seeing condensation, there is likely a problem with your gaskets or seals. This is a task that should be left to an expert.

Draughts

A double-glazed window that is draughty is an indication that the seal between the glass panes has broken and needs to be replaced. This can affect the insulation of your home and also increase the cost of energy.

Window repair services will replace your sealed unit, restoring efficiency to your windows. They can also upgrade your frames to incorporate new energy-saving features, like gas filled argon glass units that have thermal spacer bars that will reduce the loss of heat and reduce your heating bills.

Draughts can also be caused by issues with the locking mechanisms of double-glazed windows and doors, so it's important to have these checked. It's normal for older uPVC window lock mechanisms to stiffen with age. This can be easily fixed by lubricating your locks regularly using a specialist uPVC cleaner.

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


Double-glazed windows are durable and long-lasting, however they may develop problems due to weather or wear and wear and tear. Contact your local double-glazing repair services as soon as you discover any of these problems. You'll be thankful you did - a well-repaired double glazing installation will give your house that tangible sense of quality, and it will also save you money on your energy bills!

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 save energy and reduce the carbon footprint. However, double glazing may encounter a myriad of issues that may affect its performance and durability. This includes condensation, mist and being difficult to open or close.

Difficulty opening your double glazed windows could be caused by the weather or it might be a fault with the hinges, handles or mechanism. Wiping them clean with cold water and lubricating them can alleviate the issue, but you should contact the manufacturer that you purchased your windows from as soon as you can to get it repaired.

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

Foggy and fogged glass can be caused by condensation between the panes. It's typically an indication of damaged seals or an old double-glazing unit that needs replacing. This is a simple fix that can be accomplished without having to replace the entire window.

To address this issue, a technician will drill tiny holes to vent out any moisture that is trapped between the glass panes and the rest of the window. Once the moisture is removed then a new antifog coating is put on and the window is sealed. Sometimes, the window might need to be removed before this happens but most of the time, it can be done from the inside of the home.

Mist

Mist can be a huge issue with older double glazing, specifically when it happens on the outside and inside of the windows. It is caused by an issue with the seal that is designed to hold moisture and air between the two panes. This seal is created when making double-glazed units by sealing both panes with an airtight polysulphide seal or butyl seal around the edges and spacer bar. This seal is designed to prevent the window from leaking and provide insulation. It can be difficult to clean windows with mist as you must break the seal to do this.

The issue with mists is that they permit moisture to enter and cause condensation between the glass panes. This is due to a large difference in temperature between the external and internal surfaces of the glass. The moisture gets trapped in the gaps, giving an appearance of milky. It can be very unsightly and can be difficult to get rid of.

Some firms claim to be able to fix misting double-glazed windows by drilling holes in the unit and injecting a chemical through the holes, which absorbs moisture from the inside. It's not a permanent fix and it's much easier to replace the entire double-glazed unit.

The most effective method to avoid misty double glazing is making sure you have adequate ventilation and cleaning your windows regularly. Use extractor fans to reduce moisture buildup in bathrooms and kitchens. Wipe down windows with a damp cloth to avoid this. If you are unable to eliminate the problem completely We recommend replacing your double-glazed units with A-rated ones to boost the efficiency of energy.
