Working in Leytonstone
We work right across Leytonstone — E10, E11 and E17 — and in neighbouring Walthamstow and Stratford.
London homes in Leytonstone often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Leytonstone 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. If your Leytonstone bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Most of Greater London has very hard water. 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
- A backdraught shutter and external grille, so cold air does not blow back in
- 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
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.
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.
