Bathroom Extractor Fan Upgrade in Leek
Leaks, re-seals, tile and grout repairs, shower swaps and quick fixes.
The number-one cause of black mould in Leek bathrooms isn't damp — it's an undersized extractor ducted into a loft void. The steam has to go outside, not into the roof insulation.
We size the fan to room volume (minimum 15 l/s continuous, 60 l/s intermittent for bathrooms per Approved Document F), duct in insulated flexi to a fitted external cowl, and add a humidistat so it runs when the room actually needs it.
Leek is one of the areas we work in most weeks — so bathroom repairs jobs here come with a working knowledge of the street layouts.

Bathroom Extractor Fan Upgrade FAQs — Leek
- Why does my Leek bathroom still fog up with a fan?
- Nine times in ten it's ducted into the loft or is undersized. We survey the ductwork route and fan size before quoting — no guesswork on your Leek install.
- Do I need a humidistat model?
- Strongly recommended — it runs the fan when humidity is actually high, rather than only on the light switch. Pays for itself in mould prevention.
- Can you duct through a masonry wall?
- Yes — core drilled through with a fitted external cowl. We survey the exterior first on Leek jobs to avoid ducting under a windowsill or beside a boiler flue.
- How much does the upgrade cost?
- £220–£450 supply and fit for a spec-compliant fan, humidistat, ducting and external cowl. Fixed price after survey.
- Do you tidy up at the end of each day?
- Yes — dust sheets stay down, the room is hoovered daily and we leave your Leek home liveable while the work runs.
- Can you just re-seal around our bath?
- Yes — a fresh sanitary-grade silicone re-seal on a Leek bath or tray takes around an hour and is usually fixed-price per perimeter.
