My third installation (fourth if you count my old property) so I'm familiar with whole process and the materials used. Out of the four this was install that I was best pleased with. I specifically requested that Will be the fitter this time around having observed him working two years ago/2nd visit and he is the main for why we were so happy. Jack, of course was also fantastic and will learn a great deal from Will. I have run two companies since since 2008, employing 30 staff at its peak. I would be proud to have these guys representing my company so please take care of them as the finished article is only as good as the fitter. Getting ahead of the following question, I would certainly recommend Kettell to anyone local I that I know who would be considering having work carried out.
