uPVC windows are a fantastic option for modern homes. They are easy to maintain, durable and long-lasting. Unlike timber and aluminium, they are not susceptible to get rusty or decay.
It is essential to clean and oil UPVC doors and windows regularly. This will prevent unnecessary repair costs as well as improve energy efficiency.
1. Broken Glass
If the glass in your window is damaged, it could cause a large amount of damage to your home, making it very dangerous and potentially fatal. It is essential to take the time to ensure that you're doing all you can to keep your windows in good repair.
Single-pane windows are relatively simple to replace and generally fit into old frames very easily. However If windows with double panes are secured by internal beading, it will be more difficult to get rid of the old panes and put in new ones. In this situation, you will need to find some plastic spacers to help the new pane to fit correctly into the frame of the window.
Wearing protective eyewear and thick gloves is a must if you plan to remove the glass yourself. It is also a good idea to lay down a dropcloth before you begin working on the glass to ensure that any shards will fall onto the fabric rather than on the floor where they could be trodden under and cause further damage.
It's a good idea to cover the gap with tape after the glass is removed. This will stop drafts and water from entering your home until a professional comes out to fix the window. It also acts as a barrier to prevent any criminals from getting into your home. If the gap is particularly large, you may think about an alarm door that comes with an integrated window as this will offer the best of both worlds.
2. Sagging
Upvc is a long-lasting and energy efficient alternative to timber sash windows. However, with time, they are susceptible to a range of problems including sagging. A sagging uPVC window can cause issues with light, draughts and even security. If you find that your uPVC window is beginning to shrink, it's important to act quickly to prevent the problem from getting worse.
To repair a window that is sagging, you can try repositioning the hinges. To accomplish this, you'll need open the window to access the frame. With the screwdriver, you'll be able to unscrew the hinges at the top and bottom and adjust them by turning them clockwise or counter-clockwise. Close your window to test the fit after you have repositioned your hinges. If you're happy with the fit, you can tighten the screws to ensure they stay in the right place.
If you can't reposition the hinges you may require replacing the seal. Over time rubber seals can lose their elasticity and dry out which causes them to loosen. If this happens, it's crucial to replace the seal as soon as possible so that your uPVC windows remain watertight and draught-proof.
uPVC handles may also loosen up. This is often caused by screws that have become undone over time, but it can be due to the handle mechanism wears out. Fortunately, it's easy to repair the loose uPVC window handle yourself. First, you'll need close the window and perform a test fit. The joint at the corners of the sash should be aligned with the joint on the casing. If it doesn't then you can use a screwdriver to loosen the handle and reverse the mechanism back into position.
3. Water Leaks
It is essential to act if you wake up every morning to find mouldy walls and floors that are wet. Water leaks through windows can cause structural damage to your home and also impact your ability to regulate the temperature in your home. The most common reason for leaking uPVC windows is that the sealant around the frame has been damaged or missing.
It is a fairly easy fix and should be undertaken by any competent DIYer. Depending on the severity of the issue is, the old caulking might need to be removed. It is essential to remember that when it is about uPVC window repairs you should not be tempted to apply too much caulk' as this will only make the area more difficult to clean and could reduce your energy efficiency.
It is essential to ensure that the drainage holes are clear of debris and that the sill pan is angled correctly so that it drains away from the window. In more serious instances, you may need to think about replacing the window.
Other indicators of water leakage include decayed sills and the appearance of black spots of mold on the wall near the window. This fungus thrives in damp conditions and is able to quickly spread throughout the house.
If the leakage is occurring between the double-glazed glass it is more likely that the issue is more related to the seal, not the frame. Again this can easily be corrected by an uPVC window specialist who can replace the glass seal and regain the full insulation properties of your windows.
4. Faulty Hinges
If your uPVC windows are difficult to open, or are loose and open with a breeze, it may be hinges at the fault. Anyone with the skills to fix them can replace the hinges in a matter of minutes.
Like any mechanical component, hinges can wear out over time. It's easy to change a window hinge but it's much easier if someone helps you to hold the frame.
Verify that the uPVC hinges are open and closed in the correct direction. Look for the arrows on each hinge to determine which way the window should be opened.
The problem with the hinges on windows could be caused by improperly opening the window a certain way or due to inadequate installation at the factory. This issue can be fixed by sending us a photograph via our website and we will be pleased to offer you advice.
Regular lubrication of the hinges is essential. Applying an engineering lubricant that is light to the hinges is a good way to do this. We recommend using an oil that does not contain solvents, like 3-in-1 Multi-Purpose oil. Regularly lubrication makes the window easier to open and close. It also decreases the chance of windows sticking and prevent corrosion. Ideally, you should do this once a year. WD40 and other solvent-based fluids are not recommended since they can damage the parts of your uPVC window.
5. Draughts
Draughts in Upvc windows can be caused by a few various factors. The hinges can also become unbalanced due to wear, creating a gap where the sash meets frame. If they are damaged beyond repair, it could be required to realign them. The interlock, which is located on the hinge of the window and can also become misaligned, again it is possible to give them a good clean, but in some cases it might be necessary to have them replaced.
These seals are susceptible to wear and tear or become damaged over time, allowing air escape. This can be avoided by replacing them with high-quality weatherstripping. Another option is to replace the window with low-emissivity glass, this will help in regulating indoor temperatures and again will lessen the possibility of draughts.
Another method of reducing the amount of draughts is to use a draught-excluder. These are typically fabric tubes filled with a filler that can be placed over your window sill. These will help to keep cold air out and keep your home warm and cosy!

With a little regular maintenance and repair your windows made of upvc will continue to provide an excellent level of security and insulation for your home. It is crucial to realize that all windows have a life span and there may come the point when it's more efficient to replace them than fix them. If you have any problems with your window made of upvc it is recommended to speak with a professional as soon as possible.
