I think I’d just take the hit - kind of feels like when else are you gonna want to do it and if you don’t it might just be a nagging worry. Deffo not ideal though £ wise
We've got a pretty healthy contingency at the moment so even with that we are ok. As they've ripped out the floors and the rest of the house is in decent condition (including a new roof 7 years ago) I'm hoping that's the end of the nasty surprises. Lol.
Yeah that is my line of thought.
They have to cut through the steps down toward the main pipe so making good on that is part of the cost.
