In this video I replace old, condensated UPVC windows for a customer and show how I remove and refit them without damaging the plaster — even in a spotless house where detail matters.
With 20 years experience fitting windows, I talk through the real problems fitters don’t usually show you:
Taking windows out cleanly with no damage
Dealing with out-of-level window openings
Packing frames correctly so they look straight
Cutting bay window cills at the correct angles
Insulating gaps properly for a neat, long-lasting finish
This is a real on-the-tools job, no shortcuts, no rushed fitting — just practical tradesman tips that DIYers and new fitters can learn from.
If you’re thinking about replacing your own windows or want to improve your fitting skills, this video will show you what really matters.
