Shocking quality of work.

The workmanship is horrible and they don't even have the decency to get back to you when you are unhappy with the quality off work. As long as they get their money they write you off. The windows that was installed had 20mm gaps which they filled up with silicone which is now falling out. there is more silicone on the wall then in the gap between the window and the wall which is also delaminating. Numerous phone calls was made in attempt to get hold of them to come and fix the problems but with no success. I honestly wont recommend them to anyone to use as they don't care about the quality of work and has absolutely no after sales service. Pathetic to say the least.
