Working in Plymstock
We work right across Plymstock — PL9 — and in neighbouring Plymouth and Saltash.
Being a smaller town does not change how we work in Plymstock: free survey, written quote, one team. If your Plymstock bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. For windowless bathrooms in Plymstock homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Water across much of Devon is soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
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.
