I purchased a 10-year old townhouse in December. Today, when I had a contractor come to my house to quote on painting my daughter's bedroom on the 2nd floor, I was mortified to look up and see a big water stain on the ceiling. It had been painted previously as the white colour was slightly different -- the contractor confirmed this.

To make a long story short, the master bathroom directly above has a problem with the walk-in shower and will require a complete gut job. Shower, floors & counter are all marble. He said it was at least a $20,000 job - gutting, bringing up to code, redoing, tearing down the ceiling in my daugher's bedroom and possibly more depending on the damage when the drywall comes down. Neighbour in this complex had similar problem in his bathroom, said the builder didn't do the floor of the bathroom correctly, the membrane was installed incorrectly. But too much time (12 years) has passed since the place was built to go after builder.

The woman (who was a lawyer!) who sold me this house obviously knew about this problem -- because the drywall had been repaired and repainted in the bedroom below. Also, the tiles in the master shower were pristine -- they have been turning an orange colour continually on me, and I have been scrubbing with javex -- and there is also mold that keeps coming back.

She did not tell me there was a problem and if I knew I was looking at a complete gut-job for the master bathroom, I would not have bought the place. I had hired a "Mike Holmes Inspection" prior to the purchase, and they uncovered nothing -- because it was all covered over & cleaned up when the place was put up for sale.

The real estate agent was representing the buyer AND the seller -- I bought it from an open house.

Do I have the right to sue for the "cover up" or non-disclosure? And who would I sue? The problem needs to be fixed now -- there is black mold -- I cannot wait until a court case goes through the courts for years. I'm allergic to mold as is one of my daughters. What do I do ? Just sick over this --
