I have a leak in my upstairs bathroom- after a burst pipe.
They replaced one solder but they said there were still leaks when they turned on the water briefly again.

They are telling me I need to replace the upstairs plumbing.
Replacing copper with PEK.
The previous owner told me he had the upstairs bathrooms replumbed when they bought the house.

The plumbers are telling me I need to cut out my ceiling.
Then they are telling me they will replace upstairs plumbing by running parallel lines through floor beams that run across the floor.
What can Ido to have someone check to see where the leak actually is before they cut out the ceiling?
How much is replacement of ceiling dry wall and texturizing going to cost? trough down dining room side, and trouble across living room side.
