I just did this to my 2 50s era bathrooms. I hired an electrician to do the electrical work. I hired a roofer to do the work on the roof ($150 per vent), and then I hired a handyman to install the actual fan unit and go into the attic to attach the ductwork from the fan to the vent that the roofer installed. I thought this was much cheaper than hiring a bathroom company to do it. I just needed to coordinate getting the different trades to the house.

The one thing to be sure of is that when they install the fan, they vent it through the roof. That's the most important thing.

we bought a house and during the inspection we found out that our fan goes only to the attic. we will have to do some works and make it go through the roof

We had a roofing company put in the pipe when they redid our roof. We then later had an electrician do the electrical and then we just did the connection from the fan to the pipe. No big deal.

Get a honking big fan too. You get big CFM (cubic feet per minute) fan, but due to kinks in ductwork/etc. that you'll only get like 50-75% of it. I recommend something over 100 cfm minimum. Get 150+ if you can.

Also, get a timer for the fan, so it'll run long after you leave the bathroom. If you stop the fan at the same time as the light, it won't run long enough to pull the moisture out.

We had this fan installed in our master bath when we remodeled recently - it is fantastic.

I have a 1960s rambler, and somehow the master bath still doesn't have a n exhaust fan. We're getting mold/mildew, even with the door wide open, so I'd like to install one. My electrician will only do the electrical work, and all the HVAC companies I've called say they don't do that kind of ductwork.

Can anyone recommend either a person who can do all the parts of the installation, or a company that will install exhaust ductwork? I'm in Silver Spring. I'd rather not have a handyman do it, because there are so many parts (electrical, ducting, maybe roofing). Thanks so much!
