Working in Grimsby
We cover every part of Grimsby, including DN31, DN32 and DN34, and nearby Cleethorpes (1.8 miles) and Louth (14 miles).
Across a large town like Grimsby, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. We check the duct route at Grimsby surveys, because a short, straight run to outside matters more than the fan's headline figure. For windowless bathrooms in Grimsby homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch.
Most of Lincolnshire 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A backdraught shutter and external grille, so cold air does not blow back in
- A check of the room, any existing fan or vent, and the shortest route to the outside
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.
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.
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.
