No doubt, if a technical problem arises one needs quick answers and pragmatic help. This is about your property that is about to be damaged. Isn’t good advice costly? If your caretaker knows a competent expert, you only know one thing – you will have to spend more money.
Great, if your caretaker has his own in-house technical expertise. Then you will get a proposal for which you need not pay extra. It will be even better if this solution proposal is backed by decades of experience in technical building management. Then the recovery of the building stock cannot be far behind.
