Nalin in Toronto

I had them install pot lights all over my house. They also had to install lights in my kitchen. Once they left I have come to the realization that my ceiling began to get wet! I hired a plumber to take a look at it and we found out that the workers who installed pot lights drilled into the pipe above the ceiling! I am very disappointed since I paid such a huge amount of money for them to do a decent job. Instead, they drilled into a pipe which has led into a major water leak. They should know better.
