We went for a full survey, the guy is RICS-registered
Yeah, they’re chartered surveyors, you’d be wise to get a structural engineer to look it over if you were thinking of having underpinning and they might spot other things. I stopped getting chartered surveyors and asked a structural engineer I know to do the surveys - they a lot harsher.
Someone else said that a reduction of 15k is almost unheard of.
Percentage wise it’s a big chunk of change but, depending on the amount of underpinning required, it might not be enough.
even then it’s going to be a shitload of hassle
If the underpinning is not accessible from outside the floors will have to come up. Cracks in the walls may have to be dealt with by removing the plaster and tying the bricks back together then replastering. Depending on where the damp is coming from you might need a new roof - did they get up there or use a drone?
I don’t mind roughing it a bit, but managing a project like this I would think isn’t really in my wheelhouse and will be very stressful.
And money aside, this should be your deciding factor.
