OK, I started first with a company I used to clean out the drain a couple years ago. Although their tech was fine, the conclusion was $6k+ to get drain open. Called Quality First because of Martino rating. Tech opened the drain within the first hour. Cause of concern of possible trouble later, but Quality First tech did in less than a hour the previous couldn't do at all.
Quality First is now my go to company. Get it done right the first time.
