Unfortunately, recently, I've
noticed an awful smell in and around the powder room. This smell is
only noticeable if it is raining outside.

My wife complains of a similar problem, rain or shine. Seems to happen
about 6:30 every morning


Can someone give me clue as what/where
this could be coming from? There's a pedestal sink and toilet in the
powder room. My HVAC & plumber contractor has gone belly-up so I
can't call him to come smell out the culprit.

I'd still guess a blockage someplace. Traps should stop it, but if there is
a pressure buildup it may be possible to force some gasses through. Could
even be a combination of blocked vent and overfilled septic. Is it
possible that rain is getting into the septic system and overfilling it?

If you have town sewer, disregard suggestions above.
