Complete Guide to Handling a Ceiling Leak

It is a common phenomenon for residents of Singapore HDB flats to experience leaks from the ceiling. This happens due to normal wear and tear as the flats age. The ceiling is made of concrete with waterproof membranes and screed. As time goes by, the waterproof membrane and screed wears off leading to leaks. This happens in the bathroom and toilet area where water is present at all times. When this happens you need to call a waterproofing contractor singapore to fix this problem.

According to the lease agreement, the owners of the upper and lower floor units are responsible to maintain their respective flats. This means that if a leak occurs, the upper and lower flat owners will have to share the repair costs.
