Double Glazed Window Repair

Double glazing is a great investment in energy efficiency. It helps prevent loss of heat during winter months and helps to keep your home cool during summer. Repairing your double-glazed windows when needed is a great way to ensure they are in good working order.

Over time, your double-glazed windows may suffer from issues such as condensation and misting. This can cause your double glazed windows to be difficult to open or shut.

Broken Panes

A stray baseball or a stray pebble from your lawnmowers, or even a heavy storm can break the double panes of your windows, leaving your home exposed to the elements. Although a cracked glass window is difficult to repair, it doesn't need to be replaced. In fact, the insulated glass between the two panes remains in good shape and you can fix your double-pane windows with a bit of DIY effort.

To start, you'll need to take the broken glass out of the frame. This can be messy work and you'll need to be careful to stop any glass fragments from falling on the floor or falling out of the frame. Wear gloves for your hands, and place a rag around the broken glass to avoid any further injury or cuts. After taking out the broken glass, clean the frame of the window thoroughly, removing any sealant or other debris. Sand rough areas of the frame to create a smooth and even surface to install your new window.

Once the frame is cleaned, you can apply a fresh layer of glazing to the seam where the broken pane was removed. This is the best method to ensure that your window is secure and sealed, and it will help you save energy costs by keeping water and drafts from entering the house. The next step is to choose the glazing material. There are a variety of options, including clear tape which is more durable than regular tape and can keep your window secure from further cracking, and glazing film that resembles clear plastic wrap. This choice has the benefit that it can be painted to match the frame of your window and can also shield your windows from the elements like ice and rain.

Whatever material you choose, it is important to press glazier's facets into the seam where the putty meets the frame. These will hold the newly-formed glass in place and help it adhere to the frame. The glazier's point can be found in hardware stores, and they are available in pre-made ropes that you roll out onto the frame rabbets.

Condensation

Double glazing can be susceptible to condensation issues. If you experience this issue, it is best to call the company that installed the window. A lot of windows come with warranties and guarantees to address these issues. Fogging or condensation between the panes of your windows is a sign that the seals aren't working properly. Only a professional can resolve this issue by replacing the panes.

The process is complicated and requires special tools to take off the old pane and then install the new one, but it can be done by an expert who will supply the necessary equipment. Using these tools can be dangerous, however it is best to leave this kind task to professionals.

If you do decide to do this yourself, make sure you wear safety glasses and gloves to protect yourself from any broken glass pieces that might fly away during the process. It is also important to remove all putty and metal glazing points from the grooves in which the new window will be. You should also brush the frame with wire, and then vacuum or wipe it with a damp cloth. Once the frame is clean and dry then you'll need order a piece of replacement glass which is 1/8 inch less in each direction than your window, and then test it into the grooves.

You will require a layer of silicone caulk in the grooves of your frames to ensure your new glass is securely installed. After the caulk is dry it is time to smooth it and make any needed adjustments. The wood molding will then be reinstalled.

If the weather suddenly changes, double-glazed windows can become difficult to open or close. Extreme temperatures can cause frames to shrink or expand and this can make them slide or become stuck. You can try wiping down the frames with water and then lubricating them when this happens, but it may be better to consult the company that installed your windows.

Misted

When moisture gets trapped in between the glass panes, it can cause misted double glazing. Double glazing is made up of two panes, which are separated by a space filled with argon for better thermal efficiency. This results in an airtight seal that keeps warm indoor air inside and cold air outside.

The seal could become damaged over time and moisture may build up between the glass panes and cause them to become to appear misty. This happens because the space between the panes is heated by the sun, causing water vapour to develop within it.

This is a natural process, but if it occurs between the windows' panes it could cause problems because it will no longer be able to regulate the temperature in the room. Instead the temperature outside the window will influence the temperature indoors. If you notice that your double glazed windows are becoming blurred, call the experts at Northfield Glass to investigate.

We can replace the sealed blown unit without having to replace the whole window and is less disruptive than a complete replacement. Our misty window repair involves removing the glass, cleaning it, and then replacing it with a new one to create a watertight seal again.

Some companies in the industry claim that they can inject chemicals through holes into misted windows to remove the condensation and fog. We do not recommend this method. This is not just ugly, but it can also damage the toughened glass and result in windows that do not completely perform the function it was intended to.

It is important to fix the problem as soon as you can, as if untreated it can cause mould growth that not only damages the window but can also pose health risks to your family members. The condensation in the window could cause other issues with your property like damp or rot. In some instances, the window may need to be replaced entirely.

Blown or Failed

Modern double-glazed windows feature two glass panes, with an inert gas or air in between them. This improves their thermal efficiency by keeping heat in and cold out. As time passes the gas may become depressurized, causing many issues.

Condensation between the panes is one of the most common. It's not a sign of a failure in the window however it could be a sign that you need to reseal the windows. Condensation can also be a sign that your double glazing has failed and, in that case, it's time to get it replaced completely.

Double-glazed windows can also cause draughts. This could be due to an unsound seal, a broken handle, or a broken lock. It is important to fix the issue as quickly as you can. A draft will force you to spend more on heating. Test the seals on the window frame by smelling cold air.

There will also be water beads on the outside of windows if the window seals are failing. This is a sign that you need to seal your double-glazed windows.

Your window frames are designed to move slightly in order to do in order to keep the glass sheets in the right place. However, over time, this special packaging material can get compacted, and this could cause the seal to break. This allows air to flow between the panes and reduce the energy efficiency of your window repairs.

Double glazing that has ruptured a seal is an indication of failure and should be repaired as soon as possible. A damaged seal can stop your double glazing performing its primary function that is to keep the cold out and warm air in. A blown seal could let moisture in your home, which could cause mold and other unpleasant conditions. Contact a double glazing expert as soon you notice a blown window seal. They can replace the entire unit.
