What to do about gaps in screed floor around doorways in new

Hi All,

My in-laws have just had a conservatory built and I’ve offered to lay the (laminate) floor for them.

The builders have screed the floor, but it’s not particularly level so I’ll need to use some self-levelling compound to get a decent surface to lay the laminate on.

However, I’m at a bit of a loss about what to do with both the doorways in the conservatory. As you can see from the pictures below, the scree they’ve done stops before the doorway and the DPM is poking out. Below the DPM is a row of brick and then the door.

Is this the normal way of doing things or should the scree have made it all the way up to the doors?

What do I do in these areas? A SLC won’t go over the DPM to create enough of a solid surface to lay a floor on, but I’m concerned that if I cut away the DPM and then use SLC over the whole area that I might just be leaving any damp an opportunity to bridge the area.

Any advice gratefully received!

Better call the builders back in and have them sort it out properly.
Any thing you do yourself that causes problems later will render their guarantee (if any) useless for your in-laws!

Thanks for your reply WoodYouLike. So in your opinion what the builders have done here is wrong?

yeeeehaaa! typical connie job!

the floor screed should run all the way to the door and abut threshold/sill.

the top internal course, immediately between the door reveals should have been removed, the dpm laid into this space and then screeded over.

o dear, get them back to finish properly!

Thanks for your thoughts. I’ll get the in-laws to get the firm back and I’ll go around and provide support when they do come.

So what’s the most appropriate way to fix the situation?

Will the builders need to remove those visible bricks in the doorway and then screed over the whole floor again, or will they just be able to do the bits in the doorways and marry it up to what’s already been done?

the bricks will need removing as they could be a source of damp.

bricks removed, Dpm extended correctly and fill with screed/concrete etc.
