While a damaged window may be difficult to fix however, you don't have to have it replaced entirely. In fact the insulated glass between the two panes remains in good condition and you can repair your double-pane window with some DIY effort.

To begin, you'll need remove the broken glass from the frame. Be careful to avoid any glass shards falling to the floor or slipping off the frame. Wear gloves for you hands, and a rag to cover the broken glass to avoid further cuts or damage. After removing the broken piece take care to clean the entire frame of the window to eliminate any remaining sealant and debris. It's important to sand rough areas of your frame to ensure an even surface for your new glazing.

After cleaning the frame after cleaning, you can apply a second layer of glass on the seam where you removed the broken pane. This is the best method to ensure your window stays sealed and protected and will save you money by keeping water and drafts from entering your home. The next step is to select your glazing material. There are a variety of options including clear tape which is more durable than regular tape and helps prevent further cracking of your window, or glazing film that is similar to clear plastic wrap. The advantage of this choice is that it can be painted to match the frame you have, and it will keep out rain and snow too.

Whatever material you pick regardless of the material you choose, it is essential to press glazier's points into the seam where the putty meets the frame. They will help keep the glass in place and will help it stick to the frame. You can find glazier's points in hardware stores, and they come in pre-made ropes which you roll over the frame rabbets.

Condensation

If you have a problem with condensation, it is recommended to contact the window manufacturer. Many companies provide warranties and guarantees that provide coverage for the problems. Condensation and fogging in the panes of glass is an obvious sign that the seals between your windows are damaged and can only be repaired by an expert who will repair both panes.

It is a tricky procedure that requires specialized tools to remove and replace the old window. A professional can complete this job and provide the equipment. It is best to delegate the task to professionals. These tools could be hazardous.

Wear safety glasses and gloves if you opt to do it yourself. You could be exposed to glass fragments flying around. It is also important to carefully remove all putty and metal glazing points from the grooves in which the new window will go. Wire-brushing the frame or vacuuming a damp cloth are also recommended. After the frame has dried you'll have to purchase another piece of glass that's 1/8" shorter in both directions than the existing window. Test-fit the glass into the grooves.

Depending on your frames, you will then need to apply a layer of silicone caulk to the grooves to ensure that the new pane is secured in position. After the caulk is dry, you will need to smooth it out and make any necessary adjustments. The wood molding can be put back in place.

Double glazed windows can be difficult to open or close when the weather is extremely changing. Extreme temperatures can cause frames of double-glazed windows to expand or contract, causing them to sag and stick. If this is the problem, you can try wiping down the frames using water and lubricating joints. However, it might be best to ask the company that installed your windows to help.

Misted

If moisture is trapped between the glass panes, it can cause misted double glazing. Double glazing is comprised of two glass panes which are separated by an insulating space, typically filled with argon gas for better thermal efficiency. This creates an airtight seal that keeps warm room air inside and cold air outside which allows you to keep your temperature at a comfortable level in your home.

In time, however, this seal will begin to break down and moisture can begin to accumulate between the window panes, which causes them to become cloudy. This occurs because the sun's heat causes the gap between panes of windows, causing water to vapourize.

This is a normal process, but when it occurs between the window panes, it could cause problems as it is no longer able to regulate the temperature of the room, and allows the outside temperature to influence the indoor temperature. If you notice that your double-glazed windows are turning misty, call in the experts at Northfield Glass to investigate.

We can replace the individual blown sealed unit without needing to replace the entire window and is less disruptive than a total replacement. Our misty window repair involves taking off the glass unit, cleaning it, and replacing it with a new one to make a watertight seal again.

Certain companies in the business claim that they can inject chemicals through holes drilled into windows with mist to remove the fog and condensation. We do not recommend using this method. This is not only unsightly but could also damage the toughened glass and leave you with a window that does not function properly.

It is essential to address the problem as soon as you can, as if untreated, it can lead to mould growth, which not only damages the window, but also poses health risks for your family members. The moisture in the window may cause other problems with your property like damp or rot. In some instances it is possible to replace the entire window.

Blown or Failed

Modern double-glazed windows come with two glass panes that have an inert gas or air in between them. This improves their thermal efficiency by keeping heat in and the cold out. Over time the gas will become depressurized, causing a variety of problems.

Condensation in between the panes is one of the most common. Although it's a normal event, it doesn't necessarily mean that your window is failing but it could be a sign that you need to re-seal your windows. Condensation could be a sign your double glazing is damaged in which case it's time to get it replaced completely.

Double-glazed windows can also create draughts. This could be caused by a failure of the seal or a damaged handle lock. It is essential to fix this problem as soon as possible. A draught will cause you to pay more for heating. You can test the seals by placing your finger around the edges of your window frame to see whether you feel cold air.

Another indication that your window seals have failed is when you begin to notice water beading on the inside of your windows. This is a clear indication that you will need to re-seal your double glazed windows.

Your window frames are designed to move a bit and this is essential to keep the glass sheets in position. However, with time, this special packaging material can be compressed and break the all-important seal. This will allow air to flow between the panes and reduce the energy efficiency of your window.

A blown seal is a clear indication that your double glazing has failed and must be fixed as soon as possible. A blown seal will stop your double glazing from performing its primary purpose, which is to keep cold air out and warm air in. Additionally, a blown seal will let your home's moisture in, which can result in mold and other unpleasant conditions. It is important to contact a specialist in double glazing repair immediately if you spot a damaged seal in your double glazed windows, as they can replace the entire unit.
