Working in Falmouth
We cover every part of Falmouth, including TR11, and nearby Truro (7.7 miles) and Redruth (8.7 miles).
Homes in and around Falmouth vary, so we look at the floor, the walls and the water system before we price anything. For windowless bathrooms in Falmouth homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. If your Falmouth bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Supplies across most of Cornwall are 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
- A backdraught shutter and external grille, so cold air does not blow back in
- 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
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
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.
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.
