The guy arrived in less than half an hour and diagnosed a crack valve seal on the flapper. He replaced it in no time and saved us from the fuss. I am really impressed by their quick problem-solving skills and great customer service. Highly recommended!!”

“When I was selected as an administrator to a 25 storey building, I was really glad at my accomplishment. It was all going smooth until the day came when a drain valve of an apartment at the 10th story was found clogged and subsequently the drainage of the whole side of the building got blocked.
