Maintenance

Our new uPVC double glazing needs a lot less maintenance than traditional wooden windows. I remember my dad spending hours sanding, filling and painting our old windows. The new windows save so much maintenance time, but they’re not completely maintenance free. As well as keeping them clean the moving parts will occasionally need a bit of tlc.

Keep it Like New

During hot dry conditions you might have your windows and doors open a lot. This will expose the working mechanism to the air, drying it out. When the windows and doors are manufactured the come fully greased so they work easily and smoothly. This grease layer slowly dries out over time. It’s easy to keep your windows and doors in top condition, so they last a long time.

All you need to do is give the moving parts a quick spray of silicone spray every so often (around once every six months). It’s important to use silicone spray not WD40, as this goes tacky over time and may stop your windows and doors working properly. The moving parts need a light spray, to achieve this open the window or door and look at the edge, when you move the handle to open and close you will see the moving parts. Hold a cloth on the uPVC to stop the spray getting onto the frame and give these moving parts a small squirt. When you’ve done this move the handle to the open and close position a couple of times to ensure all of the moving parts have been lubricated. That’s it! We told you it was a lot easier than having to paint your old wooden windows. Lubricating the moving parts will ensure your windows and doors last for years to come.
