If you’re looking for a double glazing unit supplier then I would highly recommend EJ Cocker. For over 5 years I’ve used them to supply units for my double glazing repair company and I wouldn’t go anywhere else. Not only do they produce good quality glazed units but it’s a pleasure going there to pick them up as everyone is so friendly which creates a great working atmosphere and environment. Everyone from the office to the factory are very helpful and in my opinion you won’t get a better service in the area to be honest.
