5. Repairing Double Glazed Windows Projects For Any Budget
Repairing Double Glazed Windows

Double glazing is an investment that will benefit your home. However, over time, it can develop issues like condensation or misting.

This can be caused by a variety of reasons, but it is usually due to the seals not being airtight. This results in an absence of the insulating gases that sit between the glass panes. It is beneficial to understand how to fix double glazing.

Broken Panes

A cat's claw, a stray lawnmower ball or a stone dropped can cause a double-glazed window to shatter. When this happens the cold or hot air can move more easily between the two panes of glass and your home becomes less insulated and causing higher energy bills. If both of the windows are cracked, it's time to call an expert to replace the windows.

If one of the panes has been damaged, but not completely broken It might be possible to repair it. The first step is to remove the old pane from the frame, wearing gloves and work glasses. Then using a painter's tool and gradually warming it with a heating gun, take out the loose putty around the edges of the glass that has been broken. Use aluminum foil to protect adjacent panes from cracking while the putty is being removed.

After the frame has been prepared to accept a replacement pane use a glass-cutting tool that is cheap to lubricate (available in the majority of hardware stores) with WD-40 or another lightweight oil. Score the glass around the perimeter, roughly one inch from the edge. Then, gently shift the glass into place in the rabbets, the l-shaped grooves in the window frame where it sits. Then, use the tool's chiseled tip to rake away any remaining putty from the edge of the glass.

Press glazier's tips into the frame at intervals of six inches around the joint where the glass joins the frame. Apply a second cord of glaziers compound on the frame-glass joint and smooth using a putty knife. If windows are made of metal, you can paint the joints using a primer designed to keep rust from happening.

Cracks

Even though it is rare, double glazing cracks can happen suddenly, especially in older windows. The reason is usually due to the difference in pressure between the two panes of glass, which are caused by extreme temperature variations. It is important to keep blinds closed in hot weather and to not open them too often when the sun shines. This will prevent 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. A good double glazed window should also be easy to open and close with no sagging or sticking. Wiping the hinges and mechanism with a small amount of oil could assist, as could changing the locks and screws to ensure they're secured enough.

Be aware that a cracked glass window could be dangerous. If you have a crack in your double glazing and can see loose shards of glass on the floor, you should call an emergency glazier immediately since it's best to replace the damaged glass completely instead of fixing it.

Also, any condensation that occurs between the two glass panes tells you that there's an issue with your seals, and should be fixed straight away. A reputable glassmaker can drill into the sealed unit to inject or pump in a drying agent (typically a desiccant) to eliminate any moisture. This is a fast and cheap solution. But be aware that this is only a temporary fix and that you will have to replace your windows in the near in the future.

Condensation

Condensation can be a problem with older double glazing. Condensation occurs when moisture in the air is drawn into the space between the glass panes and then it condenses at night. This is a natural occurrence that does not signal any issue with the windows or glass. However it can be a source of frustration to homeowners as it hinders the double glazing from working as efficiently as it should.


Install vents or trickle-vents on the frame to allow air to flow, removing any condensation that may be present in your home. This will also keep the temperature in your home and reduce energy bills over time.

A professional will usually be able to fix the problem without replacing the entire window. They'll drill tiny holes into the window to let out any moisture that has been trapped, and then apply an anti-fog coating.

Contact the company from which you purchased your double glazing as soon as issues occur. This is to allow them to send a technician out to assess the situation and fix any issues before they become worse. It is recommended for all communication to be in writing. This can be done via email or a letter.

While window repair near me is possible to carry out some repairs yourself, it's generally quicker and more effective to hire a professional to perform the work. This is especially the case for issues that require specialized equipment. Furthermore an expert will usually provide a warranty for their work, which you won't necessarily receive when you attempt to fix the double glazing yourself.

Draughts

Double-glazed windows are becoming increasingly popular as they help to increase energy efficiency, cut down on the amount of noise that is heard inside the home and protect furniture from UV light. They also help minimize condensation, which is a typical cause of mould. If they're not properly installed, air can easily leak through the gaps in between the glass panes, leading to drafts.

In double glazed windows, two panes of glass are separated by a spacer bar. the gap is then filled with an insulating gas. Spacer bars usually contain a desiccant that assists in drawing moisture out of the gap, which prevents interior condensation. As the desiccant's ability to eliminate moisture from spacer bars diminishes and condensation may form between the glass panes. This is a typical issue with double glazing that's poorly made. However, it is easily resolved by drilling holes into the glass or spacer bar and inserting humidifiers.

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. The insulating performance can be improved even further by using an inert low-conductivity gas such as argon to fill the gap.

Double-glazed windows cost more to install than single-glazed windows however, they are usually worthwhile as they reduce your cooling and heating costs, shield your furniture from UV damage, and increase the value of the property. If you're considering installing double-glazed windows in your home, make sure to work with a highly-experienced installer like Thermawood. Their retrofit double glazing system allows you to take advantage of a high-quality IGU without removing the frame and the cladding.

Replacement

Double glazing can bring many advantages for homeowners. It boosts the efficiency of your energy use and reduces noise. It also helps reduce the possibility of draughts or mould building up on window panes. However, they aren't indestructible and issues can occur. You can repair most double glazing problems rather than replacing them, which will save you money and the hassle of having new windows installed.

Double glazing owners are often required to fix a leaking seal. If this is the case, it is important to get in touch with a professional to arrange for a window installer to come out and make the repairs needed.

A window that isn't easy to close or open could also be a problem. It could be due to heat or because the mechanism is stiffening up over time. If this is the case, you can try cooling down the mechanism and lubricating hinges and handles. It could also be the case that the frame is sagging or has dropped and requires re-alignment.

Misting is also a problem which can be easily fixed. This is because the rubber seals that keep the two glass panes in place become weaker as time passes. This is usually caused by the frames moving slightly as they age and compacting the particular packaging material that keeps them in place. This then leads to one or both panes of your double glazing moving and breaking the all-important seal.

Misting can be treated by drilling holes into the glass affected and then removing the moisture from within. This is a temporary solution and must be repeated. A better solution for the long run is to add trickle vents inside your frames. This will allow fresh air to enter but will not let warm air escape.
