While I sympathize with your problem but really u should take some responsibility yourself. You didn't know why your car porch is leaking and replaced the gutter. After replaced didn't check if leak still there and paid? You should pay only work is done right but one must know the problem and if the work fixes the problem.

On the ugly position of the pipe you should have agreed how it was to be done BEFORE even the work is done.

Lastly whether he is using easy wash paint or not you should have confirmed what brand he is using before work is done.

I am sorry ... to an extent you are doing this to yourself. I would never let my contractors to roam free with renovations only to discover the work is poorly done

Daily my friend. I try to get them to run by me before work is done but sometimes it is tough

My advantage is my new house is only 2 mins from current house 😬
