How to Go About Repairing Double Glazing Windows
Double glazing windows typically come with warranties that cover them for up to 20 years. If you do spot problems, you should check with the company you purchased windows from to find out what their policy is regarding repairs.
Repairing your double-glazed windows can be a simple process in some cases. Here are some of the most common problems that can be solved.
Broken Glass
Double pane windows rely on an air-tight seal to keep the outer and inner glass in place. It is difficult to take out the glass pane that has broken without damaging the frame. This kind of damage can result in a decrease in energy efficiency. Therefore, it is crucial to fix it quickly and correctly.
Repairing broken glass in double-glazed windows is a straightforward task that can be completed at home with a handful of materials and tools. To begin, remove any loose bits of broken glass from the frame. Make sure to wear gloves that are protective while doing this, since any broken glass may contain dangerous shards. After the broken glass has been removed, wash the frame of the frame using a rag dampened with acetone or rubbing alcohol to remove any traces left by the adhesive used to fix the broken glass to the window frame.
Then, you can remove any remaining glazing points from the frame using a putty knife. Once all the glazing points have been removed then clean the backside of the window frame as well as the l-shaped space where the window pane meets the frame to ensure they are free of any hardened glazing compound. Then, you can prepare for the installation of a new pane of glass by cleaning the old glass and the new frame with a wire brush. After the frame has been cleaned, apply a small amount of glazier’s putty to the edge of the glass to fix it to the frame.
Some types of windows use vinyl, aluminum or wood stops to keep the glass in place instead of the glazier's point. If your double glazed windows are made of this type, you will need to use a utility knife to cut through the tape on both sides to remove the stop from the frame without damaging it. After the stop is removed, apply a strip of strong-hold tape to the glass's surface to protect the new pane of glass to help prevent any further damage.
Seals that leak
The seals around the frame could be faulty if your double-glazed windows leak. This is a major problem because it means that all the thermally-insulating gas is leaks out and windows are losing their efficiency. This could result in costly heating bills because windows aren't as efficient as they were.
There are a few warning signs to look for to aid in preventing drafty window from developing. If you notice a slight breeze blowing through your windows when they are closed, the seal might have been damaged and require resealing. You may also notice condensation appearing on the glass which is another indicator that seals are failing.
To stop a draft, simply replace the seals on the frames. This is a difficult task that requires special tools to avoid damaging the window glass. It is recommended to contact a professional glass company to do this task, since they can utilize deglazing equipment to remove the old seals and not damage the glass.
In certain situations it is possible to repair leaky double glazed windows by using silicone putty to cover the gaps. This isn't a great option as it doesn't have a good heat resistance and could leak again in the future. But, it's worthwhile if there is no other options.
The seals on double-glazed windows made of rubber can break over time. This could be caused by the aging process, environmental conditions or the manner in which the windows are constructed. When this happens it is crucial to have the seals replaced as soon as possible to ensure that your double glazed windows are as efficient as they were when they were first put in.
A draughty
window repair is often the most obvious sign that your double glazing is not performing to its best. A draught will likely be felt at the edges of the frame where it joins the brickwork or the surrounding wall. The seal has broken and air can be able to seep into. In some instances this could result in damp patches on the surrounding walls, but this is less common.
Condensation
Double glazing windows are an excellent alternative for those who are trying to reduce energy costs and increase the insulation of their homes. But despite being durable and long-lasting, they require maintenance from time to some.
Condensation is a typical issue with double-glazed windows. Condensation is often the first indication that the window seal has failed. If the appearance of condensation is not treated quickly, it could result in mould growth and even wood mold and even wood.
Condensation usually occurs in the morning, when air temperatures are warming and humidity levels are rising and water vapour to form on cold surfaces. This includes your windows and isn't something to worry about, but it's a good idea to wipe away any visible condensation as quickly as you can in order to prevent it from spreading.
However, it's not always the indicator of a failed seal, and there are many other reasons why your double-glazed windows may be leaking. The seals made of rubber on double-glazed windows can wear down over time. This could cause them to break, which can depressurise the air gap between your glass panes. If you observe signs of condensation or misting, it is important to have your double-glazed windows repaired immediately.
