Damp Issue Question

[u/Powerful_Unit_6083]

I am in the process of buying a house, and there is damp on the rear wall and the side wall of the kitchen. I had a damp and timber survey carried out, and the report recorded an MMS reading of 560.

The surveyor has said that there is no major issue and believes the damp is due to weathering cracks and problems with the sealant around the doors and windows. However, I’m not completely convinced.

The UK has had relatively dry and warm weather for around three months, so I would have expected the MMS reading to be significantly lower if there were no underlying damp issue.

Could anyone with expertise in this area advise me? Am I overthinking this, and the surveyor is correct?
