Working in Deal
In Deal we cover CT14; we also cover Dover, 7.8 miles away, and Ramsgate.
Homes in and around Deal vary, so we look at the floor, the walls and the water system before we price anything. For windowless bathrooms in Deal homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. We check the duct route at Deal surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of Kent 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- 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
- 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.
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.
