Working in Gloucester
We work right across Gloucester — GL1, GL2 and GL4 — and in neighbouring Cheltenham and Stroud.
Gloucester is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Gloucester bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. In Gloucester flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Most of Gloucestershire has 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
- Making good around the fan and checking that it extracts properly at the grille
- A backdraught shutter and external grille, so cold air does not blow back in
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
Decisions to make first
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.
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.
