As we have dripping from Bathroom exhaust in winter, (normally after taking shower). I would like to have some tips to fix it. Also would like to know where we can find services to fix this issue?
Well sounds to me like your exhaust piping is not insulated. What happens is the warm air from your bathroom condenses inside the pipe and runs back into the fan box then into your bathroom. Its because of the piping being exposed to cold air in your attic or wall wherever it might be run through.
An easy fix you can do yourself is wrap the exhaust pipe in your attic with pipe insulation available at most hardware stores like Home Depot etc.
I'm sure there must be someone in your vicinity that can help you out if you can't or don't want to do it yourself.
Hope this helps.
Brent is correct - you should wrap your exhaust in insulation. You could also install a timer that runs the fan for an extra 20 minutes or so to remove any left over humidity.
This is available at the same stores as the duct insulation but does not require you to go into the attic.
Good Luck with it!
