It all comes down to maintenance, if you don’t know what you’re doing, don’t try to fix it, the end result could be worse than when you started. Eg. We had a client recently who was experiencing dripping water into their caravan. As a quick fix they decided to silicone up around the air conditioner unit to prevent dripping from where they thought it was coming from. This affected the airflow and as a result caused overflow water flooding the entire inside of the caravan, causing significant damage to their contents and the caravan itself.
