Our neighbour (not yet met) started some very serious drilling/hammering/sawing on their chimney breast three days ago. It's on the same party wall with us. The sound metre reads around 90db. We don't care if they work on weekends or holiday periods but definitely can't live with the noise at that level. Our first baby is expected anytime now. Is the renovation noise harmful to the little one? From our understanding their house needs a complete renovation and possibly an extension. Chimney breast removal may just be their first step. We haven't experienced any renovation noise before but is it just a short term concern or will the noise be throughout their renovation? Are there anything we can do?
