How to silicone/caulk and external window or door frame like a pro!

In this video I show how I silicone seal an external door or window to achieve a clean, long-lasting, weatherproof finish. I will explain correct silicone selection, application technique, and tooling for a neat professional result. This method helps prevent water ingress, draughts, and long-term frame damage, and is suitable for uPVC, aluminium, and timber frames. This is the same approach I use day-to-day on site to deliver a durable, tidy seal that lasts. key words external silicone sealing, external window silicone, external door silicone, weatherproof sealant, window sealant application, door frame silicone, exterior silicone sealant, how to silicone windows, how to seal external doors, professional silicone application, mastic man, sealant applicator, uPVC window sealing, aluminium window sealant, timber window sealant, waterproof sealant, construction sealant, building maintenance, exterior caulking, silicone tooling
