UPVC Window Repairs
Upvc windows can cut heating costs and are energy efficient. As they age, however, problems can occur that need to be fixed. This could include damaged handles, hinges or locks.
Wooden window repair is relatively straightforward for DIY enthusiasts to tackle themselves. It can be cheaper than buying a new window.
Cracks
Cracks and fractures in uPVC windows could be a serious issue. If they are not repaired, they can cause water infiltration and less effective protection against cold weather and even the risk of structural damage. Find a local builder who is skilled in the repair of uPVC frames. They should have the necessary skills and experience as well as the right equipment to ensure the best results. This will ensure that the fracture is repaired quickly before it gets worse and you won't have to replace your window unit or glass.
There are numerous home solutions that can be used to repair small cracks in glass. Masking tape and super glue are among the most popular products that can hold broken glass in place for a time. For deeper cracks, tape may need be extended on both sides.
Alternatively, two-part epoxy can be used to fix broken or cracked glass. This is available from most hardware stores and is available at a cost of around $10. Make sure your work area is properly prepared before mixing the epoxy. Also, make sure you have all the equipment needed to complete the task.
If your upper or lower sash isn't lifting easily it's because the cords that connect the sash's weights have been damaged. This is a simple fix that can be done using a ladder and a flathead screwdriver. A damaged dripcap can be repaired at home. The drip caps that are not rot-free are readily available at many home centers and can be nailed or caulked in place with ease. If you have a double or triple-pane window, make sure to check that one of the panes isn't broken. This is due to the gases that are leaking out between the panes contribute to improving energy efficiency and should be kept and not released.
Water Leaks
If your uPVC windows leak, it could cause damage to the interior of your home and lead to expensive repairs. Water leaks can also weaken the structure of your house and cause mold growth. It is important to fix any issues caused by leaky windows right away to minimize the damage.
One common cause of window leaks is a damaged sealant around the frame. Utilizing silicone caulk can help improve the condition of the seal back to normal and prevent water leakage. It's also important to look for cracks and gaps around the frame as well in the brick or stone walls surrounding your windows.
Another common reason for leaking windows is the drainage hole is blocked or faulty flashing. Make sure that the drainage holes haven't been clogged or blocked, especially after a heavy downpour. It's also a good idea to inspect the flashing around the lower part of your window to make sure it's properly sealed.
It is also important to ensure that your drip cap isn't broken or rotten. A drip cap that is rotten or one that's missing can allow water from above to seep into your window and cause structural damage. Replacing the drip cap isn't difficult and generally a simple process of purchasing a new one and putting it in the right spot.
A professional can also test your windows for watertightness. They can utilize a special tool to measure the water-tightness of your windows and ensure they meet the industry standards. If your windows don't pass the test, you'll have to replace them. This is a costly repair but it's worth it for the security and safety of your family.
Sagging
If your windows don't close properly, it could lead to many problems, such as drafts, condensation, and an increase in energy costs. It can also be a sign that the windows weren't well fitted when they were installed or that the sealant has stopped working. There are fortunately, a few options to fix the issue.
The first step is to prepare an area with ample natural light to fix your window correctly. Start by laying newspaper or an old blanket on the floor to protect it from any drips or splinters that might be coming from the window while you work.
Use a white cloth soaked in a mix of detergent and water. This will help prevent any color stains from appearing on your windows. Note the location of the hinge channel on your uPVC window when you are ready to start working. Unscrew the channel and fill the screw holes inside the frame using epoxy (for uPVC frames) or wood filler. Be sure to scrape the filled hole smooth before it sets.
Reinstall the hinge channel after the holes have been filled. Be sure to place it on the window jamb, and then drill the new screw holes about a quarter inch away from the original locations.
Next, measure the length of the spindle that protrudes from the underside of your handle and then order a replacement on the internet or bring the old one to the hardware store to purchase a new. Then, take out the setscrew that was on the operator shaft and smooth it out so that the set screw can secure itself to the shaft (photo). Now your uPVC windows should be closing without a hitch.
Broken Hinges
It will be difficult to open or closing your uPVC windows when the hinges are damaged or aren't functioning correctly. This could create a security problem and prevent your home from being warm or cool. It is easy to get an entirely new hinge for your uPVC window. It's crucial to choose the right type for your windows.
The hinges need to be the same size to fit into the frame of the window. The most commonly used hinges for uPVC windows are standard 18mm or UPVC 15mm window hinges. There are also specialised hinges for wooden frames. Choosing the correct window hinge for your windows can aid in avoiding common issues that homeowners have with their windows, such as not closing properly.
There are many reasons why the hinges on your windows have become stiff or loose. One common cause is that the hinges are not properly securing. To check, use a screwdriver to locate the friction screw at the hinge's end. Release it. You can then adjust it by turning it in either direction.
