Terrible and unprofessional. Jermark are the plumbers the condo management calls when there are issues in the building. I don't pay for their service and I don't like them for the attitude and mess they leave behind.
No effort to avoid damaging belongings and always musing about how annoying it is to work in the building. They've been called so many times to fix the same problem, condo wants to switch plumbers.
Avoid.
