Working in Devizes
We cover every part of Devizes, including SN10, and nearby Calne (6.1 miles) and Melksham (6.5 miles).
Devizes gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For windowless bathrooms in Devizes homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. If your Devizes bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Water across much of Wiltshire 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
- A backdraught shutter and external grille, so cold air does not blow back in
- 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
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.
