Bathroom extractor fans, kitchen ventilation and cooker hood supplies installed across Birmingham. Condensation and black mould are ventilation problems, not cleaning problems, and the right fan in the right place deals with them at the source.

Quiet, effective fans fitted in ceilings and walls, ducted properly to outside rather than into the loft.
Fans that run on after you leave or switch themselves on when humidity rises, so they work even when nobody remembers.
Cooker hood supplies and kitchen extract wired in, including hoods needing their own fused connection.
Persistent condensation and mould assessed honestly, with ventilation matched to the room causing it.
That is the overrun timer doing its job, clearing the last of the moisture after a shower. The run-on time is adjustable, so if it runs too long or not long enough we can set it sensibly.
In busy bathrooms, yes. They switch on when moisture rises regardless of whether anyone hits a switch, which is what keeps condensation and mould from creeping back in family homes.
Yes, usually reusing the existing ducting and wiring. Modern fans move more air at a fraction of the noise, and it is normally a quick visit.

Honest advice, honest pricing and a free quotation, whatever the size of the job.
