The Ultimate Guide to Maintaining and Caring for uPVC Windows 1

Why uPVC Windows?

If you are in the process of revamping your home or simply replacing your old windows, uPVC windows are an excellent choice. uPVC, which stands for unplasticized polyvinyl chloride, is a durable and low-maintenance material that offers many benefits. Not only are uPVC windows energy-efficient, but they are also cost-effective, easy to clean, and provide excellent insulation. However, like any other investment, proper maintenance is crucial to ensure their longevity and performance.

Clean Regularly

Regular cleaning is essential for uPVC windows to maintain their pristine appearance. Start by removing any loose dirt or debris with a soft brush or cloth. Next, mix a mild detergent with water and gently clean the frames, sills, and glass using a soft cloth or sponge. Avoid using abrasive cleaners or solvents, as they can cause damage to the uPVC material. Finally, rinse off the soap residue with clean water and dry the windows using a lint-free cloth.

Inspect and Repair

Regular inspections can help identify and address any issues before they escalate. Check the condition of the seals, hinges, locks, and handles. If you notice any damage or signs of wear, such as cracks, leaks, or difficulty in opening and closing the windows, it is important to address them promptly. In most cases, minor repairs can be done yourself using a uPVC repair kit, which includes adhesive, sealant, and other necessary tools. However, for more complex repairs or replacements, it is advisable to seek professional help.

Prevent Condensation

Condensation can occur on the inside surfaces of uPVC windows, especially during colder months. It is important to control humidity levels to prevent excess moisture buildup. Ensure proper ventilation in your home by opening windows or using extractors in humid areas like bathrooms and kitchens. Additionally, you can reduce condensation by using dehumidifiers, moisture-absorbing products, or simply by keeping the temperature inside your home consistent.

Lubricate Moving Parts

To maintain smooth operation, it is important to lubricate the moving parts of your uPVC windows. Apply a small amount of silicone-based lubricant to the hinges, locks, and handles to reduce friction and ensure effortless opening and closing. Avoid using oil-based lubricants, as they can attract dirt and debris, leading to potential clogging or damage.

Protect from Sun Damage

Excessive sun exposure can lead to fading, discoloration, and even warping of uPVC windows. To protect them from harmful UV rays, consider installing window film or using curtains, blinds, or shades. These protective measures not only safeguard your uPVC windows but also help regulate temperature and save energy by reducing heat transfer.

Be Mindful of Cleaning Products

While uPVC windows are relatively low-maintenance, it is important to be cautious when using cleaning products near them. Avoid using strong chemicals, abrasive cleaners, or abrasive tools that can cause damage to the uPVC material and its surface. Instead, opt for mild detergents or specialized uPVC cleaning solutions specifically designed for uPVC windows.

Regularly Check and Maintain Weatherstripping

The weatherstripping on uPVC windows plays a crucial role in preventing drafts, reducing noise, and enhancing energy efficiency. Over time, weatherstripping can wear out or become damaged. Regularly inspect the condition of the weatherstripping and replace it if necessary. This simple maintenance routine will help keep your uPVC windows secure and well-insulated.


Maintaining and caring for uPVC windows is a straightforward process that ensures their longevity, performance, and aesthetic appeal. By following these guidelines, you can keep your uPVC windows in excellent condition for years to come. Remember to clean them regularly, inspect and repair when needed, control condensation, lubricate moving parts, protect from sun damage, use appropriate cleaning products, and maintain the weatherstripping.
