Angry Smell from underneath sink

I have a smell coming from underneath my kitchen sink in the space between the sink plumbing and the wall, around the pipe. How do I seal this off?

is the joint leaking? Any water present, or just smell?

The P-trap (u shaped pipe under the sink) should be able to come apart by loosening two slip nuts. If it's leaking, you should be able to tighten up those same joints. If water isn't leaking, I can't imagine a smell eminating from that spot.

On the other hand, the smell could be coming from behind the wall.... could be a leak there in one of the joints from the drain/vent system...... or a dead mouse

No, the smell is not from a rat or the water

There's no dead animal smell.

This same smell is present under my bathroom sink too.

The smell is coming from the space between the wall and the drain pipe.
I was wondering how to seal off around the pipe...

Hmmm... I'd be concerned about the source of the smell.....

However, you can buy expanding spray foam in a can at any home improvement/hardware store. This stuff fills gaps with an expanding foam that stops air flow. It can be a little tough to work with, as it's very, very sticky and can be very very messy. Don't get it on yourself or your clothes.... it's never coming off....

Read the instructions.... and get after it...

I would not advise sealing off anything until I found the source. If it is a leak in the pipe in the wall, the smell is sewer gas. This is dangerous and should be fixed. It will just come out somewhere else. Also, if it is a leak, you will have a mold problem. Sealing off will only compound the problem. Good luck.

Lots of difference between cigarette smoke smell and sewer gas. Please make sure what it is before sealing off the pipes. Mold can be very nasty and cause illness. sealing it into a wall just helps it grow. Good luck.
