∙ 14y agoIf only the top part where the bolts go into is broken, you can use a compression retro flange that will slide into the existing 4" cast iron. This will go right over the old one. If this makes it to high, cut the top of the old flange off and use the compression.

How do you repair toilet bowl mounting flange?
depending on your type of flange and pipe and the damage of the flange, if you have a PVC flange with just the bolt slots busted then you can screw in new bolts to the floor below the flange and still use the flange but if its broken where the wax seal sits then if your flange is lower then the floor you can use a insert flange that fits inside your old toilet flange with thin walls to keep the pipe size maximum. To replace the entire flange can be a job especially if its in concrete or in a floor joist because most of the time you have no room and if its cast iron pipe it can be even more of headache but in order to replace the flange you need to cut it out to where you can reconnect the pipe and flange by using a fernco or a no hub band. Sometimes it is impossible to replace because the flange can be on all close fittings and you pretty much have to replace most of the plumbing drain pipe to replace it properly which is why you want to try repairing your toilet flange rather then replacing it .

it can cost from as little as 100 to as much as 1000 depending who does it and what is actually wrong. if the flange is cast iron it will be more. if it is glued abs or pvc and the drain is broke thats gonna cost more than 200. you may not need to actually repalce the flange and you may be able to use a metal repair bracket.

How do you install a regular toilet flange on a cast iron 6 inch sewer pipe?
If you can get to the 6 inch cast iron, you could use a rubber coupler between the cast and the flange. If it is in the concrete, put a piece of 4 inch PVC inside the 6 inch and lead it in like you would a regular cast joint. Leave the 4 inch above the floor and slide the flange over it, screw it down and cut the 4 inch flush with the flange. They make just the flange that will slide over the pipe.
How do you remove the broken closet flange from a cast iron drain pipe?
I removed the broken flange by perforating the lead filling between the drain pipe and the flange - i.e., drilling holes every 1/4-1/2 inch or so with a regular drill and then sawing through the filling with a power saber saw. Then pried the flange off with a pry bar. Wasn't as bad as I expected. - Dan
