Si Inc

Our contractor purchased and installed windows from SI, Inc. in Tucson. SI, Inc. did not alert us to the fact that alkaline from new stucco could leave what appears to be permanent spots on the glass. When contacted, SI, blew us off and denied a request that a rep. inspect the windows. They had no suggestions for how to remove the spots and told us that the windows were ruined. A professional window cleaner has been able to remove most spots using specific scouring products and a lot of effort. We will NEVER use SI, Inc. again.
