We have some areas in our house were the flooring and foundation have pulled away from the wall. How do we fill these in? Thank you
Welcome to the Bunnings Workshop community @TaylorJ. We're pleased to have you join us.
Apologies for the slow reply. It's been very busy on the site recently with so many people in lockdown and tackling projects around the homes.
Could you please tell us what kind of floors you have? It's a little hard to see from the photos. And what are the walls? Perhaps just some wider photos might help members to see what you are working with if you are unsure.
Let me also tag helpful members in @Nham, @Brad, @Prawns and @jaga to see how they would go about these repairs. Our resident Bunnings D.I.Y. expert @EricL will also be happy to help as soon as possible. Thanks for your patience in the meantime.
Thank you for sharing your question about filling the gaps between floor and wall.
My apologies for the late reply. I totally agree with your observation that there seem to be quite a number of gaps. I suggest fixing them in sections. I recommend using Sika 310ml White SikaSeal Acrylic 100 Gap Filler for the gaps on your floor. If you have old silicone attached to the wall I suggest removing them with a 100mm Sharp Edge Paint Scraper making sure not to damage the wall while removing the old silicone.
I suggest covering the gap on the ceiling with a Porta 30 x 18mm 2.7m Primed Finger Jointed Pine DAR. Measure the size of the gap and cut a piece of the timber and use Selleys 420g Liquid Nails Fast Grab Strong Adhesive to glue it on the inside gap of the crown moulding. It may be worth engaging the services of a structural engineer to find out if the movement of the foundations is severe enough to warrant a repair.

Let me tag our experienced member @JoeAzza for his recommendations.
If you need more advice or information, please let us know.
I agree with .@EricL
I had a similar problem with gaps in between floor and walls, allowing air, dust and spiders to get in, I have used No More Gaps, however, it was ok for a while, then the gap increased with time, the caulking compound gave way opening up the gap, so this time I removed all the caulking product, and got some roof and wall insulation and tore it into strips and pushed it into the gaps, then covered with skirting boards, hopefully this will work, it's been installed for over a year , so far no dust or spiders.
