How would you seal this gap around kitchen sink plumbing?
(sh.itjust.works)
This is for a rental unit, so I'm trying to keep the cost low, while also sealing it away from silverfish. I have very fine steel wool on hand as well as a tube of DAP ultra clear flexible all purpose sealant.
In that case it’s even better. Check your jurisdiction, but you might be able to get a contractor to fix it then charge your landlord.
What would be the rationale there? Bug prevention?
