before and after
Each chain is as strong as its weakest link. It is enough to break one link and the chain does not function any more. It is absolutely true in connection to communications in a building – running water, sewage, heating and electrical supply systems. Therefore we pay special attention to details used in our work. During many years we have tried what is and what is not good. We know, that good things are not necessarily expensive. But we are not so rich to buy cheap things and afterwards have them altered anew.
If you want everything to work at the first go – trust the work to GEOSAN.
