After pulling, scraping, cleaning, and caulking our windows, we still have a bunch of leaks. We used silicone weatherproof window caulk, put insulation board pieces in the big gap at the top of the window, and then used Great Stuff foam to fill the gaps from the outside.
So, what should we do now? We have to pull them out and reseal, but I'm terrified of having to do this a third time if this next shot doesn't work. I've heard people say butyl tape. Do you just put that around the edges like you would caulk? Is this sufficient or would I need an additional caulk like elastomeric sealant? Thanks.
Links to products appreciated. Really bummed we blew this money only to have to pull them back out.
