Here is my dillema. I have a brand new tiled floor on a concrete slab. The toilet flange (cast iron) was broken on one side so I purchased a "flange fixer" and secured it to the existing flange. The problem is the original flange was raised above the floor 3/8" and with the "flange fixer" it's now approx 1" above the level of the floor. What are my options here? A worker at home Depot said to have a plumber cut the flange out and install a new one flush with the floor. Is this good advise? How much does a job like this cost? Thanks for any info you can give.
