new boiler installation water leak?

[MrDerek]

Hi guys, Love this forum, long time lurker, but first time posting.

I'm getting a new boiler installed these few days, taking out the old tank fed system for a combi, relocating from kitchen to upstairs airing cupboard, pipework, brickwork etc. etc.

Day 2 of 3 right now, and I noticed there's some new stains on the ceiling directly underneath the tank. I'll mention it to them, but what can I expect to happen? think it'll be something they'll sort out or will I just get a shrug?

Not a huge issue for me to just paint over it... but just wondering what to expect.

Maybe they've had a bit of a spill when decommissioning the old tank, do you think? I'd mention it, just to find out - and then paint it over myself.
Hope the job goes well!
