Double Glazed Window Repair
Double glazing is an excellent energy efficient investment that stops heat loss in the winter months and helps keep your home cooler in the summer. Repairing your double-glazed windows when needed is a great way to ensure they remain in good condition.
Over time, your double glazed windows may experience issues such as condensation and misting. This could cause your double glazed windows to be difficult to open or close.
Broken Panes
A stray ball, a flying pebble from your lawnmowers or even a severe storm can shatter the double panes of your windows and expose your home to the elements. Although a cracked glass window is difficult to repair but it doesn't have to be replaced. In fact the insulated glass that is between the two panes remains in good condition and you can repair your double-pane windows with a little DIY effort.
First, you'll need to take any broken glass from the frame. Be careful to avoid any glass shards falling to the floor or slipping from the frame. Wear work gloves to protect your hands and use an abrasive cloth around the damaged glass to avoid further damage or cuts. After removing the broken glass take care to clean the entire frame of the window to remove any remaining sealant and debris. It is important to sand rough areas of the frame to create an even surface for your new glazing.
After the frame has been cleaned, you can apply a fresh layer of glazing to the place where the damaged pane was removed. This is the best method to ensure your window stays sealed and protected and save you money by stopping drafts and water from getting into your home. Next, you will need to select your glazing material. There are a variety of options including clear tape which is more durable than regular tape and prevents further cracking of your window, or glazing film which is similar to clear plastic wrapping. The benefit of this option is that it can be painted to match your existing frame and will keep out rain and snow as well.
Whatever material you use it is important to press the glazier's points into the seam where the putty meets your frame. They will help keep the glass in place and will help it stick to the frame. Hardware stores sell glazier's ropes that you can roll out on the frame rabbets.
Condensation
Double glazing is susceptible to condensation issues and if you experience this issue, it is recommended to contact the company that supplied the window. Many companies offer warranties and guarantees that will cover these problems. Condensation or fogging between the windows' panes is a sign that your seals are damaged. Only a professional can fix this problem by replacing both panes.
It is a tricky procedure that requires special tools to remove and replace the old window. A professional can complete this task and provide the tools. Utilizing these tools could be risky it is best to leave this type of work to an expert.
Wear safety gloves and glasses if you choose to do it yourself. You could be exposed to flying glass fragments. It is crucial to take out all putty or metal glazing points from the grooves that will receive the new window. It is also recommended to brush the frame with wire, and then vacuum or wipe it clean with a damp cloth. After the frame is dry and clean, you will need to purchase a replacement glass which is 1/8 inch less in each direction than the window that you have and then fit it in the grooves.
Depending on your frames, you will then need to apply the caulk on the grooves to ensure that your new pane is securely in position. Once the caulk has dried, you will need to smooth it out and make any necessary adjustments. The wood molding will then be reinstalled.
If the weather suddenly changes, double-glazed windows could become difficult to open or close. Extreme temperatures can cause the frames to expand or shrink and cause them to slide or become stuck. If this is the case try wiping down the frames with water and lubricating the joints. However, it might be a good idea to call the company who installed your windows to help.
Misted
Misted Double Glazing is a window problem that is caused by moisture getting trapped between the glass panes of your double glazed windows. Double glazing is comprised of two panes, which are separated by a space that is filled with argon for greater thermal efficiency. This creates an airtight sealing that keeps warm air inside, and cold air outside.
Over time however, this seal will begin to break down and moisture will begin to accumulate between the window panes, which causes them to become misty. This occurs because the sun's rays heat the space between the window panes, which causes water to vapourize.
This is a natural process however if it occurs between the windows' panes it could be a problem because it won't be able to regulate the temperature inside the room. Instead the temperature outside the window will influence the temperature inside. If you notice your double-glazed windows are turning blurred, call the experts at Northfield Glass to investigate.
We can repair the individual sealed blown unit without having to replace the whole window which is less disruptive than a complete replacement. Our misty window repair involves taking off the glass unit, washing it, and then 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 misted windows to remove the fog and condensation. We do not recommend using this method. This is not only ugly, but it could also harm the toughened glass, leaving you with a window which does not function properly.
It is crucial to resolve the issue as soon as you can, because if left untreated, it can result in the growth of mould, which not only damages the window, but also poses health risks for your family members. Moisture can also cause issues within your home, including dampness or rot. In certain situations, it may be necessary to replace the entire window.
Failed or Blown
Modern double-glazed windows come with two glass panes that have an inert gas or air in between them. This helps to improve their thermal efficiency by keeping warm air in and cold air out. As time passes the gas will be depressurized and cause various problems.
One of the most common is condensation occurring between the panes. It's not an indication of a failure in the window, but it could be a sign that you need to reseal the panes. Condensation could also be an indication of broken double glazing that will require re-installation.
Double-glazed windows can also cause draughts. It could be due to an issue with the seal or a damaged handle or lock. A draught is obvious and result in higher heating costs, so it is important to fix it sooner rather than later. You can test the seals by placing your finger around the edges of the window frame to see whether you feel cold air.
Another indication that your window seals have failed is when you begin to notice water beads on the inside of your windows. This is an indication that you need to replace the seals on your double-glazed windows.
Your window frames are made to move a bit as they have to do in order to keep the glass sheets in place. However, over time this particular packaging material will be compressed and crack the crucial seal. This allows air to flow between the panes and reduce the energy efficiency of your window.
Double glazing that has blown a seal is an indication of failure and needs to be repaired immediately. A blown seal will stop your double glazing from fulfilling its primary function which is to keep the cold out and warm air in. In addition, a blown seal can let moisture in, which could cause mold and other unpleasant conditions. Call a double glazing specialist when you notice a blown window seal. They can replace the entire unit.
