How to Go About Repairing Double Glazing Windows

Many double glazing windows come with a guarantee that covers them for up 20 years. If you do spot a problem it's worth checking with the company you purchased the windows from to determine what their policy is regarding repairs.

In certain cases, fixing your double glazing can be an easy job. Here are the most frequently encountered problems and how to fix them.

Broken Glass

Double pane windows rely on an air-tight seal to keep the inner and outer glass in place. It isn't easy to remove a broken glass pane without causing damage to the frame. This kind of damage could cause a decline in energy efficiency. Therefore, it is crucial to fix it quickly and correctly.

Repairing cracked glass in double-glazed windows is a simple task that can be accomplished at home using a few tools and materials. To begin, remove all loose pieces of broken glass. Be sure to wear protective gloves while doing so, as broken glass can contain dangerous shatterings. After taking the broken glass off, use a dampened rag and acetone or rubbing alcohol to clean the area around the frame. This will eliminate any adhesive residue.

Then, you can remove any remaining glazing points from the frame using a putty knife. Once all glazing points have been removed then clean the backside as well as the an l-shaped space inside the window frame. Clean the old glass using a wirebrush and then clean the new frame prior to installing the new pane. After the frame has been cleaned, apply a small amount glazier's glue to the glass's edge to secure it against the frame.

Some windows use vinyl, wood or aluminum stops to hold the glass instead of the glazier's points. If your double-glazed windows are of this type then you'll need employ a utility knife to cut through the tape on both sides to remove the stop from the frame, without destroying the frame. Once the stop has been removed then you can apply a strong-hold strip to the surface of the new pane of window to prevent further damage.

Leaking Seals

Seals around the frame are likely be damaged if double-glazed windows leak. This is a serious issue as it indicates that all the thermally insulating gas is leaking out and your window is becoming less efficient. This could result in costly heating bills since your windows will not be as effective as they once were.

There are a few warning signs to look for to keep a drafty window from developing. If you notice that your windows aren't draughty when closed, it could be because the seal has broken and needs to be replaced. There may also be condensation appearing on the glass, which is another indication that the seals are failing.


To stop drafts, replace the seals on the frames. But this is a complicated task that requires special tools to ensure that you don't damage the glass. It is recommended to contact an experienced glass company to complete this task, since they will be able to use deglazing equipment that can remove the old seals and not cause damage to the glass.

In double glazing repair may be able to repair your leaking double glazed windows by using silicone putty to fill the gaps. This isn't a great solution since it doesn't provide a high resistance to heat and is susceptible to leaks in the future. It's worth a shot when there aren't any other options.

It is not uncommon to see the rubber seals around your double glazed windows to wear out over time. This could be caused by environmental conditions, age or the way in which the windows are constructed. When this happens it is essential to replace the seals as soon as you can to ensure that your double glazed windows are as effective as they were when they first installed.

A window that is draughty is usually the most obvious indication that your double glazing is underperforming. A draught will likely be felt along the edges of the frame, where it joins with the brickwork or wall. The seal has broken and air is able to seep in. In some cases this may result in damp patches on the walls, though this is not the norm.

Condensation

Double glazing windows are a great option for homes that are seeking to reduce their energy bills and improve the insulation of their home. They are durable and last a long time but they still require maintenance.

Condensation is a typical issue with double-glazed windows. It is often the first sign that a window seal has failed. If condensation isn't addressed promptly, it could lead to mold growth, and possibly wood rot.

Condensation usually occurs in the mornings when temperatures rise and humidity levels rise which causes water vapour to form. This includes your windows. It's not usually a issue, but you should clean any visible condensation as fast as you can to avoid it from spreading.

However, it's not always the indication of a leaky seal, and there are many other reasons your double glazed windows could be leaking. Over time, the rubber seals in windows that are double-glazed can become worn. They may eventually break, which can cause the air gap to be compressed between the glass panes. If you observe signs of misting or condensation it is crucial to have your double-glazed windows repaired immediately.

A tradesman can fix double-glazed windows that have condensation by taking the affected pane off, then putting it back in the correct position. They will then blow hot air through the gap to eliminate any moisture. They will then apply a new seal to ensure the gap remains airtight and working as it should be.

Frame Damage

If you notice crackling sounds or other odd noises emanating from your double-glazed windows, it's a sign that one of the seals on your frame has failed. The seals keep cold water out of the gaps between the glass panes. It is important to replace them as soon as possible to stop water from getting into your home.

Fractures can crack due to general wear and tear, or from impact damage caused by pets or children. It is often possible to fix the issue with an easy repair such as using silicone to fill in the gap or sanding the area. However, more severe damage may require the insertion of new window frames which isn't something you'd want to do on your own unless you're skilled tradesman.

Another issue that is common to double glazing is that it becomes difficult to open and close. This could be the result of an accumulation of dirt or dust that has become stuck in the track, or it could indicate that there is a structural issue, such as the sash becoming warped or a frame. Depending on the severity of the issue, this may be easy to fix with a bit of elbow grease and a gentle push.

The infiltration of moisture through damaged double glazed windows could lead to dampness in your home, as well as mould and condensation. This is due to the fact that warm air inside your home is more susceptible to hold moisture than cooler air outside, and so it will easily get trapped on surfaces such as double glazing or single glazed windows that aren't properly sealed.

The good part is that these issues can be fixed and is usually cheaper than replacing your windows entirely. Double glazing problems are usually covered by a warranty that typically lasts for a period of 10 or 20 years, but certain companies offer lifetime warranties and you should always verify what yours covers before you begin work. Also, always contact your company in writing, via email or letter rather than a text message - this will make things easier if you need to follow-up with them about any issues that arise.
