How to maintain uPVC Doors & Windows A Complete Guide

Unplasticized polyvinyl chloride, or uPVC, is a type of plastic. Because it is rigid and not flexible, it is also referred to as rigid PVC. PVC in this form is commonly used for piping and window frames. It’s regarded for being incredibly durable and long-lasting, as well as giving a high level of thermal comfort. As long as it is not burned and its manufacturing is controlled to ensure that it does not cause any harm or toxicity, uPVC is a fully safe and non-toxic material. It is usually preferable to maintain them in order to increase the value of their longevity. Let’s look into some tips for the maintenance of uPVC doors and windows. These windows systems can be kept in good working order if you follow these guidelines:


Inside and out, uPVC windows must be cleaned every six months. For this, a simple soap solution and a rag will suffice. It improves the odds of discovering faults and keeps the aesthetic appeal on target. Brush all visible parts when the window opens on a regular basis. Consider purchasing a nice vacuum cleaner and cleaning them on a regular basis. If the window has good drainage, make sure to clean them on a regular basis, and if the glass is exposed to high moisture, such as terrace windows in bad weather, make sure to dry them out to avoid condensation. This would ensure the maintenance of uPVC doors and windows. The window frame should be cleaned twice a year; the more often you clean, the easier it will be to clean your windows next time. First, use a brush to remove any dust, and then clean the window frame with an uncolored, ideally white, piece of cloth dampened with water. Make sure it doesn’t leave any residue. You may also acquire a PVC cleaner from your local hardware store, but be cautious while using it because it may harm the silicone seals, causing them to lift up. Cleaning the glass four to eight times a year is typically seen to be the optimum strategy. Use a moist cloth dampened with water or glass cleaner to clean the window glass. Additionally, e-cloths can be used to clean the window glass. E-cloths were packaged with two cloths, one for cleaning and the other for drying, in order to give the glass a perfect shine. One thing to keep in mind is that cleaning windows in direct sunlight might leave a streaky surface.


Inspect the seals on a regular basis and oil the hinges and locking points. This will keep rust and squeaky noises at bay. When cleaning your uPVC doors and windows, double-check that all of the screws are securely fastened. If there are any squeaky noises, you can use any form of natural oil as a home treatment.  By following these simple measures for uPVC window maintenance, you can ensure their durability and lifespan, as well as maximize the return on the investment on the uPVC doors and windows. It’s critical to inspect the condition of your uPVC windows twice or three times a year. Check the hinge and locking points for any jarring, stiffening, or sticking. If at all feasible, clean your windows with soapy water on a regular basis to avoid any of these issues. Otherwise, lubricate the hinges and locking points with a lubricant to avoid any rattling. Last but not least, double-check that all screws are secure and not about to fall out. You may save a lot of money and, more significantly, time by taking care of this small but critical uPVC window and door cleaning task. This ensures the maintenance of uPVC doors and windows.


To keep everything running smoothly, use spray oil to lubricate the functioning parts of your windows every 6 months (handles, locking mechanisms, and, in particular, hinges). Just make sure you don’t get any oil on the glass.


Handles – while the window is closed, spray some oil on the window key and insert it into the handle lock – gently wriggle the key into or out of the lock several times.

Locking systems – spray little oil on the locking strip with the window open, then wipe away excess oil with a kitchen roll.

Put oil on the frictional hinges while the window is still open.


Although uPVC is a durable polymer that can tolerate wind and rain, it, like all plastics, suffers from heat expansion. Because uPVC expands when exposed to excessive heat, you may find that your uPVC windows and doors get rigid and do not open and close properly during hot weather. According to scientific data, at 40°C, uPVC frameworks can grow by up to 2.4cm. However, once the temperature drops, your uPVC windows and doors will return to their natural state, free of any permanent damage.

The above guide gives us an insight into the maintenance of uPVC doors and windows.
