We had an addition built 5 years ago.
Contractor attached new copper gutter to old one but corner never sealed properly. Corner always leaked but we were not aware since water was traveling between bricks and drywall. We had two contractors fixing foundation because we only saw leak in basement but it always leaked.
I called The Roof Whisperer and Arthur came by. He took a look at interior damage and pointed right away to copper gutter.
He insisted to do a water test first to assure his assumption and yes water resulted to water leakage from copper gutter corner.
Work was scheduled after two weeks and Arthur and his crew did the work.
They custom bent copper gutter since it had to match the rest of house and tested everything after work. We fixed all the bricks and interior after two months and not a drop of water. I am very happy we finally resolved the problem.
Thank you to Arthur, John and Alex.
