A few months ago I purchased an old (45 years) home. The main bathroom was not vented. We did a few minor improvements (carpet, painting, kitchen flooring, etc) and had a handyman in to help out. I asked him to install a vent in the bathroom which he did.

I just noticed this week that he only vented the bathroom to the attic and not directly out of the home via the room or the wall. The attic does have venting, but is this adequate? Will it create problems for me? (I'm in Edmonton Canada so we see plenty of cool weather)

How large of a project is it normally to vent to the outside? I don't think I will tackle the project myself as my handyman skills are a little on the low side. What type of tradesperson should I hire?

Oh YES, this will cause problems... and I'm sure its NOT to code in Canada. The roof will be cold in winter, blow warm moist air into it and you get condensation just like a cold beverage in a glass in summer. It will eventually cause both Mold and rot. It MUST be vented outside directly, either via the roof or through the wall, never into the attic.

I agree, big problem. The bathroom must be vented outside. If you have him come back he will likely try to run a 3" galvanized tube duct to the eaves and down out the soffit, not good either. The tube will need to be insulated to stop condensation. The tube can not terminate in the soffit because the moist hot air will just be drawn back into the attic wher it will condense.

What type of contractor is best suited for this project? I don't think I'll have the same guy come by again.

Just a suggestion... But a Roofer that's not excusively a roofer?

Be there when its done and make sure as was mentioned above... they use an insulated duct.

I think the greatest room for error is getting it through the roof... and remaining leak free. That's why I suggested that.

Thank you. Appreciate it.
