Replacing an existing extractor fan is often simpler than new installations. Using the old mount, wiring, switch, and duct setup makes it an easier DIY project if you understand basic electrical connections and safety. Again, there can be nuances and rules and regulations surrounding working on electrics, especially in the bathroom, which is why our clients just end up going for the low risk option and contracting us in to carry out the project.
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.
In a nutshell, we will recommend and install a system we have a warm fuzzy feeling will put a real noticeable dent in the sort of symptoms you're currently experiencing. The sorts of ventilation systems we fit certainly aren't cheap, but they do produce the results, as many of our past clients have come to find out!
