"Allcool recently tinted a number of wood framed north facing windows at our house, which required the existing film of some 35 years to be removed and then new film re-applied. Very hard to fault the professionalism of Bill, Charlie, Courtney and Mick the installer, who although a contractor, was courteous, punctual and skilled. They were also the cheapest of the three quotes i received, but I was confident in their product and ability to do the job and they didn't let me down. Highly recommended!"
