Damp on inside of conservatory wall at bottom

Anonymous user 16/03/2024 - 2.39 PM

We’ve moved into our current detached home 18 months ago. We noticed a damp patch at the bottom of the conservatory wall where it joins the house a month ago. It appears to have started above the skirting boards and now spreading sideways and upwards. Black mould has started on the patch which is concerning. It has also extended onto the wallpaper in the adjacent dining room. It is next to a door frame. The conservatory is probably 15-18 years old. This damp patch is on the lower right aspect of the wall. We noticed a leak causing damp at the left upper aspect of the same wall during heavy rains 6 months ago. This has been checked and is due to flash banding being done originally and old gutters so is currently being properly repaired. I understand that it is difficult to advise without actually inspecting the area. My questions are: 1. What is the most likely reason for the right lower aspect damp patch? 2. Could it be related to the other leak as they’re both on either side of the door ? 3. Which professional do I need to choose when posting a job to inspect it & fix? Would it be the same professional or different professionals? Thanks in advance!
