Why install an extractor fan? Everything Knowle homeowners need to know.

If you have noticed lingering smells in the bathroom or condensation constantly building up on mirrors and tiles as well as an un pleasant humid atmosphere in the wet room, you may have a ventilation issue. 

You might think opening the window once in a while is enough but actually it isn't. At Fairway Electrical, I’ve seen the disastrous consequences of poor ventilation rates in bathrooms caused by steam given off during hot showers and baths. Excess moisture can build up over time leading to black mould growth which is a stubborn and recurring problem. Your best bet is to consider exactor fan installation to constantly expel moisture and odours from your bathroom in Knowle.

Can I DIY extractor fan installation?

Bathrooms are considered “special locations” so fitting an extractor fan requires an understanding of regulations to meet safety standards. Electrical wiring into light circuits and including an isolator switch are considered typical jobs when installing an extractor fan. As this is classed as notifiable work, you do need a qualified electrician. Lucky for you, Fairway Electrical are NAPIT approved electricians which means we can self certify on work falling under Part P of the Building Regulations.

How long does extractor fan installation take?

A standard upgrade which involves removing an old fan, replacing with a new unit and testing the system only takes 1-2 hours. New installation in an extension or where a fan does not previously exist requires more complex work. As an experienced electrician I know exactly what I’m doing so I work in an orderly manner to cause little disruption to you. A homeowner close to Wells Road surgery was so pleased when the new extractor fan was installed in a matter of hours. It meant the busy mum could make it to the school pick up on time.

What factors affect the cost of extractor fan installation?

More complex or new installations cost slightly more as this requires cutting a hole into a ceiling or wall, installing flexible ducting and wiring the isolator switch on a wall outside the bathroom. The length of ducting can also influence the cost. Running ducting through a loft requires more material and does take longer but it’s still an option for a bathroom in a loft conversion. Finally, the type of extractor fan will determine the overall cost too. More advanced technology such as low trickle settings and quieter fans are more expensive than the basic model. Having installed many extractor fans across Knowle, I would be happy to give you recommendations to suit your budget.
