Working in North Watford
As well as North Watford itself (WD2, WD24 and WD25), we survey in Watford, Bushey and Rickmansworth.
Homes in and around North Watford vary, so we look at the floor, the walls and the water system before we price anything. Fans fitted in North Watford bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. If your North Watford bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Supplies across most of Hertfordshire are very hard. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A check of the room, any existing fan or vent, and the shortest route to the outside
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
Rules that apply in England
In England, Approved Document F sets bathroom extract at 15 l/s for an intermittent fan or 8 l/s for continuous extract. Wiring a new fan alters a circuit in a room with a bath or shower, so it is notifiable under Part P.
