I had my gutters/fascia replaced about eighteen months ago. Since they were installed I have had leakage, particularly where the gutters join my neighbours. In heavy rain they also overflow over my backdoor. The fitter came back twice and tried to remedy the problem but no joy -the leakages are persistant. he also told me it was because the neighbours gutters were dirty (which they are not because I checked). He tells me he won't come again because he has done all he can!!!!!!! Has anybody else had a similar problem and how did you resolve it?
