I am currently in the process of buying a house, it's 20 years old. I had a homebuyers report done, which was generally fine, the main issue is a leaking drainpipe. I have just been up to look at the exterior in the rain and there is a clear damp patch visible where it's leaking.
The surveyors report made no mention to damp inside.
Would you ask the vendor to fix the guttering prior to completion? I don't know if it's too petty an issue worry about (especially if it slows the sale down). Or should I just get it done as soon as possible once in?
