I used waterworks based on homestars rating. Michael came to look at a leak in our shower recess that was flooding through to the kitchen below. After a few hours of cutting holes in our ceiling and in the wall behind the hand basin, he determined the leak was most likely coming from a nail, from our built in wardrobe on the other side of the wall, that had punctured a pipe. I didn't believe him for a minute - the wardrobe had been there for 5 years, the leak had not, so I asked my handyman to come and give me a second opinion.
Our handyman, $25/hr, diagnosed the problem immediately. It was obvious that the tiles in the shower recess had lifted, I could see daylight through them! So my handyman fixed the mess Michael had created in our ceiling and walls and fixed the shower recess too. This is incompetence beyond belief.
