Five Repairing Double Glazed Windows Projects For Any Budget
Repairing Double Glazed Windows

Double glazing is an excellent investment for your home. However, over time, it may develop issues such as misting or condensation.

The cause can be due to a variety of factors, but it is usually due to the seals not being airtight. This leads to an absence of the gases that insulate that sit between the glass panes. Finding out how to fix your double glazing will help.

Broken Panes

A stray ball from the lawnmower or a stone that has been thrown around even a claw from a cat can cause a double-glazed glass pane to break. When this happens it is possible that cold or hot air can move more easily between the two panes glass which makes your home less well-insulated and increasing your energy costs. If both windows have cracked then it's time to contact an expert to replace the windows.

If one of the panes is damaged but is not completely broken it could be feasible to repair it. The first step is to take the old pane from the frame wearing gloves and a pair of work glasses. Then using a painter's instrument and gradually warming it using a heat gun, remove the putty that is loose around the edges of the broken glass. Apply a piece or aluminum foil on the panes that are next to it to prevent them from breaking after the putty has been removed.

When the frame is ready to accept a replacement pane lubricate a cheap glass-cutting tool (available in most hardware stores) with WD-40 or a similar lightweight oil. Score around the perimeter of the glass, approximately an inch in from the edge. Then, place the glass into the rabbets (the grooves with an l) in the window frame. Use the chiseled edge of the tool to remove any excess putty around the edge.

After the new pane is in place, press the glazier's facets into the frame every six inches around the seam where it meets the glass. Apply a second glaziers compound on the frame-glass joint and smooth with a putty blade. If your windows are metal, paint the joints with an anti-rust primer specifically designed specifically for your particular type of metal.

Cracks

Although it's not common double glazing cracks can happen suddenly, especially in older windows. It's usually caused due to pressure differences between two panes which are caused by extreme temperature fluctuations. It is crucial to keep blinds closed in hot weather, and to not open the blinds too often when the sun is shining. This will stop excessive heat from building between the two panes.

The best way to prevent cracks in your double-glazed windows is to ensure the frames are secured, particularly on the hinges, locking mechanisms, and handles. A well-constructed double glazed window should also be easy to open and close without sagging or sticking. Oiling the hinges and mechanisms may assist. You can also adjust the screws and locks to ensure that they are tight enough.

It's important to keep in mind that a damaged window is not just ugly, but can be very risky. If you have cracks in your double glazing and can see shards of glass that are loose on the floor, contact an emergency glazier immediately as it's probably best to replace the broken glass entirely instead of fixing it.

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

Condensation

Condensation can be a problem with older double glazing. Condensation occurs when moisture from the air is drawn into the gap between the glass panes and then it condenses at night. This is a natural occurrence that doesn't indicate any problem with the glass or windows. However, it can be frustrating for homeowners since it stops the double glazing from operating as efficiently as it should.

The solution is to add vents or trickle vents to the frame, allowing air to flow through, removing the possibility of condensation forming in your home. double glazed window repairs will also keep the heat in your home and reduce energy bills over time.

A professional will usually be able to fix the problem without having to replace the entire window. They will drill tiny holes through the window to let out any moisture that has been trapped and then apply an antifog coating.


Contact the company where you purchased your double glazing as soon as any issues arise. It is essential to contact the business you bought your double glazing from as soon as you start experiencing issues. This will enable them to send a technician to assess the situation and fix any issues before they get worse. It is a good idea for all communication to be written. This can be done through mail or letters.

It is possible to repair certain things yourself, but it is typically faster and more efficient to hire a professional. This is especially the case for issues that require specialized equipment. Additionally, a professional will typically offer some sort of guarantee 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 can be heard inside the home and prevent damage to furnishings from ultraviolet light. They also help minimize condensation, which is a typical cause of mould. If they're not properly installed, it's easy for air to leak through the gaps between the panes of glass and cause draughts.

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 bars typically contain a desiccant, which assists in drawing moisture out of the gap, thus preventing internal condensation. As the desiccant's ability to draw moisture away from spacer bars diminishes and condensation may form between the glass panes. This is a common problem with poorly-made double glazing, but it can be easily repaired by drilling holes into the glass or spacer and then putting in the dehumidifier.

The space between the two panes of glass in a double glazed window acts as an insulator 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 in the gap.

Double-glazed windows are more costly than single-glazed windows to install, but they're often well worth the cost as they can reduce cooling and heating bills, help to protect furnishings from UV damage, and increase the value of your home. If you are considering installing double-glazed windows into your home, work with an experienced installer like Thermawood. Their retrofit double-glazing technology allows you to take advantage of all the benefits of a quality IGU without removing existing frame and cladding.

Replacement

Double glazing can bring many benefits to homeowners, it improves energy efficiency and reduces condensation and noise. It can also reduce the risk of draughts or the build-up of mould on your window panes. They are not indestructible and occasionally, issues can be encountered. It's worth remembering that you can typically repair most issues with double glazing repaired, rather than replaced, saving you the cost and hassle of having new windows fitted.

One of the most frequent problems that homeowners with double glazing encounter is having to fix a leaky window seal. If this is the case, it's essential to contact a professional as soon as you can to schedule an appointment for a window fitter to arrive and make the required repairs.

A window that is difficult to close or open could be a source of trouble. It could be due to heat or the mechanism is stiffening up over time. If this is the case, try cooling the mechanism down and lubricating the handles and hinges. It may also be that the frame is slightly sliding or has fallen and requires realignment.

Misting is another issue that can be easily repaired. This is because the seals made of rubber that hold the two glass panes in place wear out over time. This is usually caused by the frames shifting little as they age, and the special packaging material that keeps them in place, which can result in one or both panes of your double glazing shifting and breaking the all-important seal.

Misting can be corrected by drilling holes in the affected glass and removing the moisture inside. This is temporary solution, and will likely need repeated. Installing trickle vents inside your frames is a better long-term solution. They allow fresh air into the room, but they also block warm air from getting out.
