Expensive repair for slab leak: what’s this going to cost?

[Daniel Z Fang]

Hello bp!

One of my properties has a slab leak in the bathroom. A plumber went out and quoted 4K to remove the tub, excavate the slab, cut back until healthy line is found, and replace the line w pvc extension. After this is done, we’ll still need to level the concrete, replace the tile in the bathroom and address any flooring issues created from repairing the leak. Has anyone done this type of repair before? I’m wondering how much I can expect to pay when this is all over and whether there are any alternative options here. Thank you.

Hi Daniel,

Just some things off the top of my head to discuss with your contractor/plumber/workmen (if have not already).

Sometimes "Remove the Tub" means cut it up with a big saw into pieces or break the surround into unusable pieces.

This will add to the job cost due to replacement of the tub and surround.

It may depend on the workmen doing the job (different people do things differently), or how the tub and surround are constructed.

Where I'm going with this, is your "Fix the leak bid, may not include replacing the tub and surround (and floor) to the condition they were before the demolition work.

If this is true, the restoration to original will be an extra charge. New tub, concrete pour, new tub install, etc... 

There is also clean up of the waste and debris to consider. What will happen to the old things and the concrete dust and rubble. Will it be left as a pile in the bathroom or will it be disposed of. Does your city allow disposal of such items at the curb, or must you or your contractor provide a dumpster. (Do they intend to dump the concrete rubble and dust down the Water Closet and just flush it--probably not best).
