Get a quoteWhat actually happens on a bathroom fan job, and who is responsible for it?
A bathroom fan job with The Wire Guys is quoted on what we can see, and if the scope changes once the ceiling is open, we tell you before we do it.
- The estimate is free, and the work is $135 an hour for a Red Seal electrician plus a helper.
- Where a permit is needed, we pull it and attend the inspection.
- Anything unrelated we find gets your approval before we touch it.
The four questions
Bathroom fan installation cost: what changes the price
Bathroom exhaust fan installation cost comes down to our hourly rate and three things about your bathroom.
We charge $135 an hour for a Red Seal electrician plus a helper. The estimate is free. Our Google rating is 4.7 stars across 137 reviews. Tracing a fault is the exception: $165 for a 45-minute diagnostic tells you what the problem is and how we will fix it.
What changes the price:
- Swap or new fan. A like-for-like swap keeps the bathroom fan replacement cost down, and a new fan where there was none costs more.
- Access above the ceiling. Open attic space above the bathroom is quicker to work from than a finished floor.
- Power at the spot. Wiring that already reaches it saves time.
Bathroom fan replacement or new installation
A noisy bathroom fan is usually a worn motor bearing or a build-up of dust, not a wiring fault.
Like-for-like swap
In a like-for-like swap we fit the new fan into the existing opening and reuse the wiring.
New fan
A new bathroom fan installation where none exists, often part of electrical work during a renovation, needs a new housing, a switch leg and a route for the air to reach outside.
Bathroom fan repair sometimes means the motor, the switch or the supply rather than the whole unit, and working out which one is electrical troubleshooting and repairs. If you notice a burning smell from the fan, stop using it and call.
Condo bathroom fan replacement usually needs strata approval, because the duct can run through shared parts of the building.
What a bathroom fan timer switch or humidity sensor changes in the wiring
A timer switch or humidity sensor keeps the fan running after the switch goes off, so it needs a permanent live alongside the switched one.
Can a bathroom fan with light share a switch or a circuit?
A bathroom fan with light can run off one switch for both, or off two so the fan can stay on after the light goes off.
Does a bathroom fan need a permit, and who meets the inspector?
Whether a bathroom ventilation fan installation needs an electrical permit in BC depends on the work. A new circuit always does, and a fan replacement that changes the wiring may as well.
In Abbotsford, Chilliwack, Mission and Langley, the permit comes from Technical Safety BC. In Vancouver and Victoria, the city issues its own.
We pull the permit
Where the job needs one, we file it with whichever authority covers your address.
We are there for the inspection
Someone from our crew meets the inspector, so you are not left explaining wiring you did not do.
Who installs bathroom exhaust fans: an electrician, a handyman or you?
Choosing a fan or cleaning a grille needs no licence, but you need an electrician to install bathroom fan wiring that adds a switch leg, a circuit or a timer.
The exception is a homeowner electrical permit, which lets you wire a bathroom fan yourself in a detached home you own and live in.
Homes with aluminum wiring in older homes need a different kind of connection to a new fan, so mention it when you book.
Where the moisture goes
Bathroom fan venting into attic space
Bathroom fan dripping water is usually condensation in the duct, not a wiring fault.
An insulated duct keeps warm, wet air from cooling and dripping back through the grille, and a backdraft damper at the outside keeps cold air from blowing back in once the fan shuts off.
The BC Building Code (Section 9.32, Ventilation) requires bathroom exhaust to discharge to the outdoors, not into an attic or soffit space, and sets a minimum air-flow rate for the fan.
- Vented to the outdoors.
- Ending in the attic.
Our bathroom fan installation process
Three things happen on every bathroom fan job we do, from the first look at the old fan to the final test:
- 01
We show you what we found.
Before any work starts, we walk you through what is wrong.
- 02
Nothing extra without your approval.
If we find anything unexpected, we talk it through with you and get your approval before any extra work begins.
- 03
We test the fan and show you it works.
It runs in front of you before we pack up.
What happens if it fails inspection, or is not right after we leave?
If an inspection does not pass on our work, we put it right, call the inspector back, and we cover the cost.
If something we installed is not right, we come back.

This was our third time using The Wire Guys and again they did a great job! NaNak removed an old, noisy ceiling fan in the main bedroom and replaced it with a silent, modern one that works like a charm. He called before arriving, removed the old fan, installed the new fan, showed us how to work the remote control and then cleaned up the area and took the old fan away to be recycled. We are very happy with the services The Wire Guys have provided us and would recommend them for anyone's electrical needs.

How much does it cost to install a bathroom fan if one doesn't already exist?
A new fan costs more than a like-for-like swap, because it needs its own housing, a switch leg and power brought to where it will sit. Where there is no attic above the bathroom, fitting a new fan can mean opening part of the ceiling.
Can you replace just the bathroom exhaust fan motor?
A motor alone can be swapped if the housing is sound and a matching one exists for that model, but replacing the whole fan is usually simpler. Parts for older or discontinued models are often hard to find, which usually settles it.
Do ductless bathroom fans actually work?
A ductless bathroom fan moves air around the room, but it does not remove moisture from the house the way a fan vented outside does. It can suit a bathroom no duct can reach, but the damp stays in the house.
Why is my bathroom fan not working?
A bathroom fan that won't start usually has a seized motor, a failed switch or timer, a tripped breaker, or a dead supply. Check the breaker first. The estimate is free, but tracing a fault like this is $165 for a 45-minute diagnostic.
What size bathroom exhaust fan do I need?
Fan size is rated in CFM, and the right size depends on how big the room is and how far the duct runs to get outside. CFM means cubic feet of air per minute, and the number is on the fan's box.
Do bathroom fans need to be vented outside?
Yes. Bathroom exhaust is meant to leave the house, not end in the attic, where the moisture condenses and drips back through the grille. It also soaks into the attic insulation and the roof framing, which is where mould starts.
How long should a bathroom fan run after a shower?
Run it until the mirror clears and the room stops feeling damp. A humidity sensing bathroom fan starts on its own once the air gets damp and shuts off again when it dries. A timer switch instead turns it off after a set time.
Does a bathroom fan need its own circuit?
Not always. A standard bathroom fan draws very little power and often shares a circuit with the bathroom lights, while a fan with a built-in heater draws a lot more. The instructions for a heater model say what circuit it needs.
