Working in Thornaby-on-Tees
We cover every part of Thornaby-on-Tees, including TS16, TS17 and TS18, and nearby Stockton-on-Tees (2.5 miles) and Yarm (3.1 miles).
Being a smaller town does not change how we work in Thornaby-on-Tees: free survey, written quote, one team. Fans fitted in Thornaby-on-Tees bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room. We check the duct route at Thornaby-on-Tees surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of County Durham is moderately hard. Scale is a minor issue next to condensation, which is what a properly sized extractor fan is for. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A check of the room, any existing fan or vent, and the shortest route to the outside
- 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
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
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.
