Repairing Double Glazed Windows

Double glazing can be an investment that will benefit your home. However, over time, it may develop issues such as misting or condensation.

It could be due to a variety of reasons but is usually due to the seals no more being airtight, causing an increase in the gas that acts as an insulation between the glass panes. It can be helpful to know how to repair double glazing.

Broken Panes

A cat's claw, a stray lawnmower ball or a stone thrown can cause a double glazed window to shatter. This allows cold or heat to move more easily between two layers of glass, which can result in lower the insulation and causing higher energy bills. If both of the windows have cracked and you're in need of an expert to replace the windows.

If one of the panes is cracked but not completely shattered it could be feasible to repair it. The first step is to remove the old pane from the frame wearing gloves and work glasses. Remove the loose putty from the edges that are broken of the glass using the painter's tool, which you can warm with a heatgun. Use aluminum foil to shield the glass from cracking as the putty is being removed.

Once the frame is ready for the new pane, you need to make sure to lubricate the cutter using an inexpensive glass cutting tool -- available in most hardware stores -- with light oil such as WD-40. Cut the glass along the perimeter, about one inch from the edge. Then, put the glass inside the rabbets (the l-shaped grooves) in the window frame. Then, use the tool's chiseled tip to scrape any putty that is left over off the edge of the glass.

Press glazier's tips into the frame in intervals of six inches around the joint where the glass joins the frame. Then apply another cord of glazier's compound to the frame-glass joint, and smooth it with the putty knife. If your windows are made from metal, you can paint the joints using a primer designed to prevent rust.


Cracks

Even though it is rare double glazing cracks can occur suddenly - especially in older windows. It's usually caused due to pressure variations between two panes of glass, that are caused by extreme temperature fluctuations. It is essential to keep blinds closed in hot weather and to not open them up too much when the sun shines. This will stop excessive heat from forming between the two panes.

The best way to avoid cracks in your double glazed windows is to make sure that the frames are secured, particularly at the hinges, locking mechanisms and handles. Double-glazed windows must be simple to shut and open and should not sag or stick. Oiling the hinges and mechanisms may aid. You can also adjust the screws and locks so that they are secured enough.

Be aware that a cracked glass window could be dangerous. If you find shards on the floor, or a crack in the double glazing, it's recommended to contact an emergency glazing expert. It's better to replace the broken glass rather than attempt to repair it.

Also, any condensation that occurs between the two glass panes tells you that there's an issue with your seals, and must be addressed immediately. A professional glazier with a good reputation will be able to drill into your sealed unit and inject or pump dry agent, usually a desiccant into the window to rid it of any moisture. This can be a simple, cheap and effective solution to this problem. Be aware that this is temporary solution and you'll need to replace your windows in the future.

Condensation

Condensation can be a problem with older double glazing. window repair occurs when moisture from the air is pulled into the gap between the panes and then is able to condense during the night. This is a normal occurrence that does not signal any issues with the glass or windows. However it can be a source of frustration for homeowners since it stops the double glazing from working in the way it should.

The best solution is to add vents or trickle vents to the frame and allow air to flow through, thus removing the possibility of condensation forming within your home. The addition of this feature will also aid in keeping heat inside the house and reduce energy costs in the long run.

A professional will usually be able to solve the issue without having to replace the entire window. They will drill tiny holes into the window to expel any trapped moisture, and then apply an anti-fog coating.

Contact the company where you purchased your double glazing as soon as any issues arise. This is to allow them to send out a technician to check the situation and resolve any issues before they become worse. It is recommended for all communication to be written. This can be done via email or a letter.

It is possible to repair certain issues yourself, however it is generally faster and more efficient to work with an expert. This is particularly applicable to issues that require specialist equipment. A professional can also provide an assurance on their work, which you might not receive if you try to fix the double glazing yourself.

Draughts

Double-glazed windows are increasingly popular because they improve the efficiency of energy, lower the noise levels in the home, and protect furnishings from UV rays. They can also reduce condensation which is a frequent cause of mould. However, if they're not properly installed, it's easy for air to escape through the gaps between the glass panes, causing drafts.

In double-glazed windows, two panes of glass are separated by a spacer bar and the gap is then filled with insulating gas. The spacer bar typically contains desiccant, which helps draw moisture out of the gap and prevent interior condensation. However, when the desiccant is no longer able to remove moisture from the spacer bar, it is possible for condensation to form between the panes of glass. This is a common problem with poorly-made double glazing however it can be fixed by drilling holes in the glass or spacer, and after that, putting in a dehumidifier.

The space between the two panes of glass in a double-glazed window acts as an insulation by limiting the transfer of cold air from outside to your home. Filling the gap with an inert gas, such as argon, may improve the insulating properties even more.

Double glazed windows are more costly than single-glazed windows to install, but they're often well worth the investment since they can reduce cooling and heating bills, help to protect furniture from UV damage and improve the value of your property. If you're considering installing double-glazed windows in your home, make sure to work with an experienced and skilled installer like Thermawood. Their retrofit double-glazing technology allows you to enjoy all the benefits of a quality IGU without removing the frame and cladding.

Replacement

Double glazing has many benefits for homeowners, it improves energy efficiency, reduces noise and condensation. It can also help to reduce the possibility of draughts or the growth of mould on window panes. However, they're not indestructible and there are times when problems can arise. It's important to remember that you can usually get most double glazing faults repaired, rather than replaced, saving you the cost and hassle of having new windows fitted.

Double glazing owners are often required to fix a leaking seal. If this is the case, it's important to contact an expert as soon as possible to set up a suitable time for a window fitting professional to arrive and make the required repairs.

Another issue is when windows become difficult to open or close. This may be due to heat, or perhaps because the mechanism has become stiff over time. Try cooling the mechanism down and lubricating hinges or handles if this is the problem. Alternatively, it may be that the frame has slightly fallen or sagged, and requires to be aligned.

The misting could also be easily fixed. It happens because the rubber seals that hold the two glass panes in place wear out over time. The frames can move in a slight manner in time and the packaging material that keeps them in place shrinks. This causes panes to move, and break the seal.

Drilling into the affected glass is a way to eliminate moisture. This is a temporary solution and must be repeated. Installing trickle vents in your frames is the best long-term solution. They allow fresh air to enter the room, while preventing warm air from escaping.
