When both elderly garage door springs snapped (i.e. sprung apart), everything that needed replacing was replaced and as good as new the very next day.
So, in that respect, I'd like to give a shout out and the Five P's to technician Frankie Linton who, in no particular order, was:
Professional, Polite, Punctual, Patient & Perfect.
Thank you, Frankie. A good job very well done.
