The Upvc Spares 4 Repairs team has spent a lot of time filming video tutorials on how to undertake Upvc Window and Door related repair tasks. A lot of repairs are often quite easy, once you know how! For example changing the lock (euro cylinder) on a Upvc door is a very simple task, once you have measured the existing lock cylinder to obtain the PZ size. We're hoping our video tutorials give the average person the confidence to undertake a repair on a Upvc Window or Door. At the time of writing we have 82 videos on our YouTube channel, so chances are we have one for a repair you might be considering undertaking. View: Spares 4 Repairs on YouTube. Remember, if its Upvc we can help!
