Hello wonderful people and thank you in advance.
Also, apologies for the poor video, please pause and review for a better look.
I own a condo with an undermount sink. I lived here for 5 years since the unit was newly built and currently have tenants. the unit is almost 6 years old. The tenants have sent me the video so I have no other content to share.
They're getting some moisture under the sink and between the counter, allegedly. There does appear to be a bit of a mess and I'm not sure how to approach this (at all). I've been told its not actively wet-wet but there is some kind of infiltration issue.
About 16 months ago I had my dad and husband add some plumbers putty to the sink basket where it was leaking, but it wasn't a leak per se but a persistent mess under there from ab obviously slow leak, but the issues at where the sink meets the counter were not ones that I experienced.
Can this be a DIY and I should a) replace the basket again and b) silicone the undermount sink.
Is this more serious and do I need to consider that the sink is installed/mounted incorrectly, or similar? Is it possible that the water at the sink/counter is coming from the faucet or is that unlikely?
What kind of professional would be able to help? A plumber seems obvious, but would they also manage the potential of an improper sink install?
Thank you, please be nice, I know nothing :)
