*** Installer cracked multiple pieces of siding and then walked away like it never happened ***Sub-contracted to install patio door. Installer came and did his work, said he was all done, and then left. When I went to look at it from the exterior, I saw multiple pieces of siding had chunks missing from it.When I received a call from CGI to schedule repairs, I asked that someone different comes out to do the work. The person I spoke to gave me a VERY hard time about this and said hed check with the company that contracted with them to do the work.I believe in giving people a chance to fix a mistake, but when you cause damage like this and walk away like nothing happened, you probably are ethically challenged and therefore not someone you want working on your house again.
