How to maintain UPVC windows and Composite Doors

Modern UPVC windows and Composite Doors are in most homes, but they are not completely maintenance free. UPVC lock and hinges really benefit from a little TLC which can help their long term condition. Follow the tips below and you will be able to minimise the wear on your UPVC fittings for a longer product life.

1. Oil the working parts

Oil all moving parts like the locking strip on the edge of the door/ window and the spindle of the door handle at the very least annually (it’s best every 6 months). Here’s where all the bolts and other locking parts operate. If you handle is starting to stick something and the oil does not solve this then your door as probably dropped and could need realigning. Tip if you are having to lift the handle to engage the lock then this needs some adjustment.  

Important note about oils.

Don’t use sticky traditional oils like WD-40. WD-40 is great for purpose: it displaces water and oil really well, but if left in place WD-40 will eventually make your lock stickier. The problem is oils like WD-40 go sticky over time and collect dust and gunk deep inside the lock. You are better off using modern silicon or PTFE lubricants

Thankfully, UPVC Windows and Composite doors are much lower maintenance than traditional wood products. However, a regular once over of your door, windows and frame with some soap and water makes a long term difference in preventing the build up of any dirt or grime. It’s possible for muck to build up over time and cause problems for door or window mechanisms.

To clean the frames and panels of your doors and windows, you only need a soft sponge and warm soapy water. Don’t use anything abrasive as micro-scratches will only encourage grime to take hold. The soap doesn’t need to be fancy it can be normal hand soap or washing up liquid. Just be thorough and clean all around all the surfaces.
