Reasons for damp/moisture in single brick extension

Hi, I have a single brick utility/garage extension which runs along the side if the main house (original survey indicated it was built later). In the back of the house is the kitchen which leads into the utility section of this extension. There is a damp or moisture issue affecting a particular section of the back wall of this extension in the bottom corner where it meets the original house. This can be seen via peeling paint and painted skirting being damaged. It seems to also extend along the perpendicular wall which separates the kitchen/utility at low levels. There appears to be damp proof course on inspection outside but unsure of its condition. Of possible reasons for this that I can think of; The area not insulated inside - room isnt thermally effiecent compared to kitchen. Room contains dryer, washing machine, fridge - condensation forming? No evidence of any on windows in room. Brick pointing looks poor in area directly outside where the issue inside is (crumbling in places). 2 drainpipes for washing machine and bathroom feed out into drains in area outside close to where pointing is weak. Pipes dont extend all the way into traps so chances of water splashing on brick? Any advice would be appreciated on how to identify the main cause(s) and best remedies.

I'd have to come and look to give proper verdict.

Hi, this sounds like something we can help with. My initial thought is rising damp as a result of a failing DPC. We provide a FREE damp Survey. We would welcome the opportunity to visit you to investigate this further. If as I suspect it is rising damp we will explain the best course of treatment and leave you with a 12 month no obligation quotation to cure the problem. We then also provide a follow up Survey in the future to provide you with the reassurance the problem is rectified. All our work is provided with a 20 year warranty. I hope this helps. Chris
