Working in Southall
In Southall we cover UB1, UB2, UB5 and 1 more postcode districts; we also cover Greenford, 1.5 miles away, and Heston.
London homes in Southall often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Southall bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. In Southall flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Water across much of Greater London is 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
- Making good around the fan and checking that it extracts properly at the grille
- A check of the room, any existing fan or vent, and the shortest route to the outside
- 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
Decisions to make first
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.
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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.
