    “Kolorseal offer a fantastic service and are a pleasure to deal with. The turnaround time of our quotes is especially impressive, which enables us to close sales more effectively” Also on another matter, we have a lady who has had a Composite Door installed and she is really unhappy with the colour of the outer frame (nothing to do with you) Are you able to offer a spray service for installed products ? I know a few companies have sprung up offering this, but would rather use you.
