Working in King's Lynn
As well as King's Lynn itself (PE30), we survey in Wisbech, March and Spalding.
Homes in and around King's Lynn vary, so we look at the floor, the walls and the water system before we price anything. If your King's Lynn bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. If your King's Lynn home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply.
Water across much of Norfolk 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
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Making good around the fan and checking that it extracts properly at the grille
- 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
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.
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.
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.
