Good afternoon. If the repair is not a single one, but for the whole house, then in this case you need to sign a cooperation agreement. In Toronto, POM Plumbing Company are the most sought after in this area. I know that in our district all the houses are serviced by this company. And our house works with this firm, including. Thank God, but in the three years that I live here, we have never had any emergency situations and global breakdowns.
