If you are suffering from general condensation, with the most obvious tell-tales being: Wet windows in the morning, wet glazing of tiles after a bath or shower, and the same again when cooking, you could benefit from better ventilation. If you also happen to suffer from mould in these areas, you certainly should be looking to improve your ventilation.
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!
