Unsealed bathroom!

[yonderfive]

There's no seal between the tiles and the walls in my bathroom, and just open floorboards under the bath, also the sink and toilet are not sealed at the back. We've had two mice suddenly appear on the landing and can only assume they've come from the bathroom.
Can anyone advise me what to do?
Or who would fix this for me? Is sealing even the term? I'd like it sorted ASAP as newborn in the house and quite paranoid! Thanks

I wonder what proportion of mastic people are women?

I am definitely more skilled at sealing the bath than my husband (I am a woman).

But whenever I have called a tradesperson out to fix plumbing / heating / electrics / anything (not mastic as I can do that!) it’s always been a man that has turned up. Seems like a reasonable assumption to make that the mastic person would be a man.

There was a time when nearly all doctors were men, but it's no longer o to use the term lady doctor.

ok not o.
