How to seal gap in granny flat window?

[Bekommstenicht_]

Hi there, I just moved into a super cute granny flat. The only problem I have is that it’s surrounded by maaaaaany trees and native gardens with lots and lots of Spiders, ants and Cockroaches. I’ve already removed a white tailed spider from my room and I have a little ant problem but pest control is going to come in for that one. However, I have a few gaps in the flat that makes it really easy for insects to enter. One is the one in the photo. The wall on the left (opposite window) is not sealed so there’s a gap into the actual wall which seems to be a perfect hiding spot for spiders. I will speak to the landlady at some point but I’ve already pestered her with the ant problem and don’t want to bring up a thousand issues at the same time so I’m looking for a temporary fix to close that gap. Doesn’t have to look pretty at this point since you only see that corner when you are in the shower.

Hi @Bekommstenicht_,

Thank you for your question about sealing gaps in your new place and welcome to the Bunnings Workshop community, it is fantastic to have you with us.

For the gap pictured, I'd suggest using some cardboard to create a template that fits tight in the gap.

Once happy with your template, trace its outline onto some corflute and cut out the shape.

Put the corflute in place then seal the edges with Wet Area Silicone Sealant.

When it comes time to remove it, you can push the corflute out and peel back the silicone.

Let me know what you think.
