call your building director, thats what they are there for, I have a problem with my neighbour upstairs dragging furniture, hammering, drilling, i have complained several times, then I wrote an official complaint to the president of the association, had a log of the noise, minute by minute, they are renters, so they wrote a letter to the owner of the condo, advising him that if it continue it will be a fine of $100.00 per day, the noise slowed down, then it started again, so I called security and it has got a lot better, PLEASE DO NOT KEEP SILENT, we have to restore the order in this place is out of control and we paid good money for it, we deserve peace and quiet in our golden years, good luck
