We are seeing an increase recently in the number of balconies on Victorian and Edwardian properties, failing due to corrosion of embedded reinforcement or steelwork supports. These structures have lasted well, more than 100 years, but it seems that time is at last catching up with them. Tell-tale signs of potential problems include rust stains on the underside of balconies, balustrading coming loose and cracks appearing in the floor finishes. If you have an old balcony, it’s worth keeping an eye on it.
