Our favourite extractor systems tend to live up in the loft, so really the only part of the entire ventilation system you see is a pretty looking chrome (or white) cover on the ceiling.
Nobody wakes up one day and says, "I need extra ventilation", without good reason. Ventilation systems are usually ordered to solve a problem, or to prevent a problem before it occurs. We can fix condensation throughout a property, poor ventilation and removing bad smells in kitchens and w/cs - we can't fix water ingress, leaks or rising damp with ventilation alone.
