How to install flashing to seal shed / vermin proofing

[Rona]

Hello 

Looking for advise please i have brought some aluminium flashing and silicone for sealing the inside and outside bottom of shed . 

Before install I have cleaned out all dirt, taken out Tex screws and put flashing in.

Have installed one section see photos, installed flashing to block holes and silcone sealed along all edges. 

Will this last ? Any advice? 

See photos thank you

Hi @Rona 

What you are  doing is so incredibly hard and I lov your work so far.

But if you targeting mice  for example or snakes.  They are so skilled at the smallest gaps to get through and the standard shed metal has all these corregations that a rat  could get thourgh  with ease.  With all your  work there I still can see gaps between the foil and the cement  edge.

Can I suggest you buy some  premixed sand and cement 1 bag  per 2 meters  as a guide. mix it  up and take out the foil and from the inside of the shed fill the cement in between shed  wall and the concrete floor in that space . The cement will block of everything including water except for floods.

Buy an inexpensive pointy  trowel or a  small garden trowel to aid you to get into the metal corregations and make it all smooth.

Hello Jewelleryrescue 

Thanks for your reply really appreciate it, 

If I put concrete in between the gaps isn't it going to rust the colorbond? 

I am mainly worried long term the flashing won't last, will it corrode? I was also going to put steel wool on the inside because I know rats and snakes can't eat it, this will fill any gaps at the bottom. 

Thanks Rona

Welcome to the Bunnings Workshop community @Rona. It's wonderful to have you join us, and many thanks for your question about sealing a shed.

The aluminium flashing you’ve used is well-suited for this purpose and should last without issues. Aluminium is naturally resistant to corrosion and, with proper installation and sealing, it will remain durable over time. The silicone sealant you've used is also a good choice, as it helps to ensure that any gaps are properly sealed to prevent water and pests from entering. Adding steel wool inside for extra protection against rodents and snakes is a smart move as well. Overall, with the steps you've taken, your flashing installation should serve its purpose effectively in the long term.

Please let me know if you have any questions.
