Working in Portslade
We work right across Portslade — BN3, BN41 and BN42 — and in neighbouring Hove and Shoreham-by-Sea.
Portslade gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Portslade bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. We check the duct route at Portslade surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of East Sussex is 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A backdraught shutter and external grille, so cold air does not blow back in
- Making good around the fan and checking that it extracts properly at the grille
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
Decisions to make first
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
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.
