Velux?

cool tunes man. was this something about windows?

How do you get the glass out. Do you run a utility knife underneath to cut silicone.

I can’t believe there are no comments. Can you provide link to where you got the perfect replacement piece?

Ah, the video I've been looking for. Um gonna replace a rotten window sill using a similar tool to what you used and replace the sill with a UPC jobbie I'm a 70 year-old DIYer, but I should be able to manage the job okay. Thanks for taking the time to upload the video.

Kinda left a lot out of the " replacing" part of the video. Also , I want to blow my brains out listening to that music.

Even if the video only shows the removal of the sill I really liked it. I'm gonna get me a Makita oscillating tool as well
