Sika fenstertechnik gmbh is an average company. Their website sika-fenstertechnik.de provides decent information about their products and services. However, I found their customer service to be lacking in responsiveness. I had to follow up multiple times before I received a satisfactory response from them. Overall, I would rate my experience with Sika fenstertechnik gmbh as average.
