Installation nightmare.
The installation was bad from the beginning. They started the work, with poor instructions, so they said. They made persuasive excuses as to why the installation had to be done in that way but the work quality was still poor, at best. When they came out to fix it as we had asked, they did only a partial fix and made other matters worse, as there was no attempt to clarify. They always returned when we were not there. The gutter lengths were cut an inch too short. The hole saw cut into my wood and into the back side of the gutter material. The contact said the would use rubberized washers and 50 yr tri-polymer sealant. Washers were standard and basic silicone was used as sealant. I am still trying to manage an equitable outcome.
