Partial brick/DPC replacement below rear door?

[JimTMC]

Hello all,

Full honesty, I'm a complete DIY novice and I'm hoping to get some advice on an issue I've discovered on a property I've recently moved into.

Previous owner had installed decking below the rear door to the garden, I've removed this and can now see the bricks and DPC below the rear door to the garden appear to have crumbled away, 3 bricks in particular are lose and I believe can be easily removed by hand. (Pictures attached)

All the other surrounding bricks appear to be fine.

The white plastic at the top on some pictures is the underneath of the rear door sill.

I know the concrete floor outside is way too high, this will be removed in the near future.

My immediate plan is to remove these and replace with new bricks, but my concern is with the state of the DPC.

Is it possible to remove a section and replace? is this something I could attempt myself or am I best getting a professional in?

Interior of the house seems absolutely fine and there is no evidence of any damp so, as awful as the DPC looks it appears to be doing its job still but I'd like to avoid any future issues.

Thank you in advance for any advice you can provide!

Is that a slate dpc?

Personally looking at the perps below the dpc I would be removing the concrete floor then having another look - I suspect more horrors await you

Thanks for the reply!

Yeah it's slate DPC - is that going to impact any sort of repair?

Sadly I think you're right! I'll be trying to get the concrete floor up this week

No no , no impact on the repair , though you will struggle to remove the slate without breaking it
