I'm after a bit of advice. I've recently had some building work done, part of which was a detached office and workshop in the garden. The builder is under the impression that his job is complete, but upon inspection today, I can see that the cavity closers are still on display in the floor. I'm presuming these should be screeded over to give me a floor I can do something with? I've added a couple of pictures (I hope) for clarity.
Cheers in advance for any advice.
