How to Repair Double Glazed Windows
There are a few distinct indications that your double glazed windows require repairs. Draughts and water ingress are clear signs of damage to the frames of your windows. They must be fixed in the shortest time possible.
However, misting can also be an indication that your window seals need replacement. Replacing the window seals will solve the issue and prevent leaks, draughts, or condensation.
Broken Panes
One of the most frequent problems that a double-glazed window faces is broken glass. Double-pane windows are less difficult to break than single panes, yet accidents do happen. You should repair broken glass as soon as you can.
The first step to take is to remove any glass shards that are not completely removed that remain in the frame. Be sure to wear a pair of gloves and eye protection while doing this, since glass can be very sharp. Once the shards have been removed, inspect the floor of your home for other pieces that are loose. It's also an excellent idea to pull out any metal hooks holding the panes together.
Once the glass is removed, you'll need to remove the old glazing compound (small fasteners that fix the glass in the window frame), and replace them with new ones. This is a time-consuming procedure and requires some tools to accomplish the task. This includes latex glazing putty; metal glazing points; pliers; a heat gun and a putty knife.
When you are removing the old glazing compound and points, it's a good idea to start at the top of the sash, and move down. This will prevent getting any of the paint or sash's wood stuck to the tool. Also, if you remove some of the sash's wood make sure you employ a chisel or a utility knife instead of a chemical stripper as this can cause damage.
When you're done ensure that you sand any bare wood to smooth it. When the wood is smooth, you can seal it using linseed or clear wood sealer. This will protect it from water and further damage.
There are a few simple solutions you can try to repair a damaged double-pane window However, these solutions will not repair the crack and should be used only as a temporary fix. Use of silicone caulk will help seal the gap. However it is crucial to use a high-quality caulk and proper application methods.
Condensation
If you notice a haze of moisture or mist between the glass panes of your double glazing it means that the window seal isn't working. This could be a cause for concern because it stops gas or the insulating air from being trapped between the two panes of glass, so it won't do its job correctly and this will lead to temperature changes that cause condensation to form.
Fortunately, the issue can be fixed by an expert in double glazing. The window company will take out both the window sash and window as well as the IGU (insulating unit) to correct the issue. Then, a new gasket will be blown in to create an airtight seal to prevent condensation from occurring in the future. They will also apply drying agents to aid in drying the area out and prevent the condensation from happening again.
The other reason why you may notice mist between the glass panes of a double-glazed window is that the framework has shifted over time, which causes cracks in the seal that is so crucial. This can be a problem since it means that your windows won't work correctly and will lose energy efficiency.
Although it is possible to replace the panes of a double-glazed window but this can be quite expensive and is typically only required in the event of serious issues with a window that are beyond repair. If you're experiencing problems with your double-glazed window but are still within the warranty period, you might be able to repair it for free or at lower cost.
Verify the warranty conditions prior to contacting the company to determine if they can resolve the problem without replacing the entire window. Double-glazed windows typically have warranties of between 10 and 20 years. It is possible that the company can fix the window unit instead of replacing it. If this is the situation you're in, they'll send a professional to repair your double-glazed windows. They can usually accomplish this in a short time. This is a less expensive alternative than purchasing and installing brand-new double glazed windows and it's also better for the environment!
Broken Locks & Handles
If the handle on your window is broken or difficult to open, it can be a major problem as it makes it impossible to use your windows. This could also give burglars an opportunity to gain entry into your home. There are several ways to fix it but the best option is to speak with a uPVC expert. Based on the severity of the issue they are able to usually come and repair it for you or at the very least, provide you with an alternative handle.
There are many kinds of window locks but the most popular is the Maco or Mila locks that are found on most uPVC frames. These locks employ bayonet rods to lock and these can easily seize up. If this occurs, the handle's nase will be stuck in the popped out position, and cannot be returned to the locked wedge. This could be a frustrating problem, but it can be solved with just a few steps.
To fix the issue, you'll need to remove the handle. This is simple enough using the help of a screwdriver. After removing the handle, you will be able see the screws that attach the lock to frame. Once the screws have been removed you can then use a wrench or pliers to attempt to grab the bolts for the shoot. If this doesn't work then you can place the tool into the gap between the frame and the window (the gap could be different at the ends of the windows) and create an "u" shape using your fingers to grasp the bolts.
If you are able to unblock the bolts that shoot, then you can shut your window by adjusting the handle into the closed position. The gearbox (espag, espagnolette, etc.) is most likely damaged and won't open with the handle. It is possible to refit the gearbox without the shoot bolts, thus the window will be opened with the handle (and it will remain secure) However, you'll require a new handle and gearbox.
Broken Hinges
If your uPVC window hinges are no longer operating smoothly, you may need to repair or replace them. It could be that the window was opened too vigorously or the hinge snapped. They could also have a problem. Thankfully the replacement of the hinge is quick and easy, so there's no need to purchase a new window instead, you can get your old windows repaired instead.
The first step is to remove the hinges currently installed. This is done by removing the screws that hold the hinges to the frame. After you've removed the hinges and replaced them with plywood boards cut to the right size. Make sure the plywood is thicker than the original board to ensure it can support the weight of the window both open and closed. Use wood filler to ensure the hole left behind by the old hinge will not leak or become loose.
After you've replaced hinges and filled the holes, you'll need to paint them. Use a quality paint to make sure it lasts as long as it can. After the paint has dried and you are able to attach the window again. Make sure you tighten any loose screws.
Window hinges also require regular maintenance. Cleaning the track of friction and lubricating hinge mechanisms will ensure they last longer. You can also apply wood preservatives to protect them against the elements. This will help prevent corrosion and ensure they look great for as long as you can.
