Browse Forums Windows & Doors 1 Aug 09, 2021 11:01 am Hello. I've been inspecting around the exterior of a new house we moved into, and noticed that several of the windows have these large gaps at the bottom edges of the window frames. Curiously, some appear to be sealed all the way with the black seal material, while others fall short and thus leave a gap. See below: Gaps Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Gap covered Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Is the inconsistency a sign of lazy construction? Should I seal off these big gaps or do they serve a critical function? During windy days, we can hear wind getting into the cavity of the walls that are facing the wind and causing rattling and the plasterboard to sort of flex with an audible crack/pop. I have read about a few options in sealing gaps, such as expanding foam, backer rods, and sealant. Any recommendations on best practice? Cheers! Re: Large gaps around exterior window.

Then find a remedy for the one, maybe an aluminium angle in black in the gap and caulked top and bottom. Just make sure you don't caulk over any weep holes that may be under the sill or you will have leaking into your home.

You wouldn't recommend sticking expanding foam into the existing gaps and then sealing over what gaps remain? Sure, IF you know what you're doing. There's expanding foam that grows as it is still curing and it can destroy your window so be careful.
