Double glazing is an excellent energy efficient investment that stops loss of heat during winter and keeps your home cooler during the summer. Repairing your double-glazed windows when required is a great method to keep them in good condition.
Over time, your double-glazed windows can suffer from problems like condensation and misting. This can cause your double glazed windows to be difficult to open or shut.
Broken Panes
A ball that is rogue or a stone flying from your lawnmower or even a storm that is strong enough can break your double pane windows which can expose your home to the elements. While a damaged glass window isn't easy to fix, it doesn't need to be replaced. The insulated glass that is between two panes of glass is still in good shape and you can fix your double-paned window on your own.
You'll first need to remove any broken glass from the frame. You'll need to be careful to keep glass shards from falling to the floor or falling from the frame. Wear work gloves to protect your hands, glaziers and place a rag around the broken glass to avoid further damage or cuts. After removing the broken glass, clean the frame of the window thoroughly, removing any sealant or other debris. Sand rough areas of the window frame to create a smooth surface to put in your new glass.
After cleaning the frame, you can apply a new layer of glass to the place in which the broken pane was removed. This is the best method to protect and seal your window. It can also save you energy costs by preventing water and drafts from entering your home. Next, you will need to select your glazing material. There are a variety of options, including clear tape that is more durable than regular tape, and can prevent further cracking of your window or glaziers glazing film, which is similar to clear plastic wrap. This choice has the benefit that it can be painted to match your frame, and will also keep out snow and ice.
Whatever material you use, it's important to press the glaziers points into that seam where the putty meets your frame. These will hold the new glass in place and help it stick to the frame. You can find glazier's points in hardware stores, and they are available in pre-made ropes which you roll onto the frame rabbets.
Condensation
If you have a problem with condensation, it's recommended to contact your window manufacturer. Many companies provide warranties and guarantees that will cover these problems. Condensation and fogging in the panes of glass is an obvious indication that the seals between your windows have been damaged and can only be fixed by an expert who will repair both panes.

Wear safety gloves and glasses if you choose to do it yourself. You could be exposed to flying glass fragments. It is important to take out any putty or metal glazing points from the grooves that will receive the new window. Wire-brushing the frame or vacuuming a damp cloth is also recommended. After the frame has dried you'll have to purchase a replacement piece of glass that is 1/8" shorter in both directions than your existing window repairs. Test-fit the glass into the grooves.
Based on the frames you have You will then have to apply a thin layer of silicone caulk to the grooves in order to ensure that the new pane is securely in the right place. Once the caulk has dried it is time to smooth it and make any needed adjustments. The wood molding will then be put back in place.
Double-glazed windows can be difficult to open or close if the weather changes dramatically. Extreme temperatures can cause frames to shrink or expand and, as a result, they can fall or stick. If this is the case you could try wiping down the frames with water and then lubricating the joints. However, it might be best to ask the company that installed your windows for help.
Misted
When moisture gets trapped in between the glass panes, it can cause misty double glazing. Double glazing is comprised of two panes, which are separated by a space filled with argon for greater thermal efficiency. This creates a airtight seal that keeps warm indoor air in, and cold outside air out.
In time, however, this seal will begin to break down and moisture will start to accumulate between the window panes, causing them to become misty. This happens because the gap between the panes is heated by the sun, which causes water vapour to develop in it.
This is a normal thing to happen but if it happens between the window panes it can cause a problem as it can no longer control the temperature in the room, and allows the outside temperature to affect the indoor temperature. Northfield Glass can help you in the event that your double-glazed windows begin to mist.
We can replace the blown sealed unit without needing to replace the whole window and is less disruptive than a full replacement. Our misty window repair involves removing the glass, cleaning it, and then replacing it with a fresh one to create an watertight seal.
Some companies in the industry claim to inject chemicals through holes into windows that have been misty to eliminate the fog and condensation. We do not recommend using this method. This method is not just unsightly but could also damage your toughened glass, leaving you with a window that doesn't function properly.
If you don't address the problem immediately, it could lead to mould, which could not only damage the window, but pose health risks to your family members. Moisture in the window can also lead to other problems with your property, such as damp or rot. In some instances windows, they may have to be completely replaced.
Blown or failed
Double-glazed windows consist of two glass panes with an inert or air between them. This helps to improve their thermal efficiency, keeping the cold out and heat in. Over time, this gas may depressurize which can lead to a range of problems.
Condensation between panes is one of the most common. It's not an indication of a window failure, but it could be a sign that you need to reseal the panes. Condensation may be a sign your double glazing is damaged and, in that case, it's time to get it replaced completely.
It is also important to look for draughts coming from your double glazed windows. This could be caused by the seal being damaged or a damaged handle lock. A draught can be quite evident and can result in higher heating bills Therefore, it is essential to fix it sooner rather than later. Test the seals on the window frame by smelling cold air.
You will also notice water beads on the interior of windows when your window seals aren't performing as they should. This is an indication that you have to reseal the double glazed windows.
The window frames you have purchased were designed to move slightly and this is essential to keep the glass sheets in place. However, with time, this particular packaging material will become compacted and this will cause the seal to break. This will allow the air to circulate between the panes, which will reduce your window's energy efficiency.
A seal that is blown is an obvious sign that your double glazing is damaged and needs to be fixed immediately. A blown seal stops your double glazing from fulfilling its primary purpose, which is to keep cold air out and warm air in. A blown seal can also let moisture in your home, which could result in mold and other unpleasant conditions. Contact a double glazing expert immediately you notice a blown window seal.
