I have renovated a few very old houses in New England over the years and I would say that one of the most important things to focus on is proper installation of lead flashings. Properly set up, it will last for ages and ages and ages. Particularly in climates that go through thaw/freeze/thaw cycles, flashing is absolutely pivotal to keep at that hard work in good shape. Flashings aren't sexy and no one tends to notice but when done correctly it's overWHELMingly useful!!

I'm redoing my CT home exterior, removed all 2 layers plus old sheathing boards (so many nails). Last owner replaced all the weight single pane windows but left the old framing and didn't use tape or anything inside it, sigh. I don't want to remove 22 windows really. Will the z flashings save me for the most part? I'm trying to figure out windows and how they she's water. It hits the window and comes down and hits the sill and runs off it with the kerf? So I just need to flash the head and sill plate as far back as I can and I'm good? Do the sides too? I can use tape but not sure how to approach this old house :(

I found that it works a lot better leaving it stick out a little bit from window so water drips off rather than running down the wood of window trim the paint holds up way better on the window

Fkashing: Windows; flashing along the top edge of the windows and doors, prevents water from rotting out wood casements. Along the edge of a roof and around the chimney, flashing under the edges of the roof, also prevents water rots and if you are building, an edge along the bottom, up about a foot, directs rainfall away from your house and protects your basement. My name is on my other post.

What if you’re adding a fancy crown to the top of the window? Should the flashing above the entire window (trim and all ) or can it just be above the window (in my case... where the new windows I had replaced filled the old hole)?

They do sell wider flashing for this case but if extra wide, I highly recommend people just going to a siding/roofing supply place and get custom pieces made up. Cheap and easy. I do custom brake work/flashing professionally, and this video seems kind of misleading, both in title and demonstration. They didn’t flash a window and didn’t even make a piece long enough. Tricky and unnecessary method..

This does not explain anything about how to flash a window, as the title suggests. It's an instructional video for how to DIY custom size aluminum flashing pieces. :/ Also, shouldn't the metal flashing extend past the window casing somewhat to keep the water off?

@mattgrill3311 4 жыл бұрын

This is an incorrect detail. The flashing should be pitched away from the house, or else water will just sit there and eventually make it’s way down the legs of the window. Which also leads to the point, the flashing should have end dams Bent up, forcing the water out. This is not a detail that the DIY homeowner should tackle, it is meant for a professional window installer. This is why so many people have issues with water intrusion around windows, no one understands building science and proper moisture management.
