Most joinery work in London passes through three or four companies before it is finished: one shop machines it, another builds it, a spray shop coats it and a courier delivers it. Every hand-over is a week of waiting and someone new to blame when a panel arrives short.
We do all of it ourselves in Croydon. Estimators, CAD, machinists, bench joiners, sprayers, quality control, counter staff and drivers are all employed here, and they sit within a few metres of each other. When a sprayer spots a filled edge that will ghost through the topcoat, they walk to the bench and say so — the job is fixed that afternoon rather than argued about the following month.
It also means one person can answer the phone and tell you the truth about where your work is: which machine it is on, how many hours are left, and which day it is booked out for delivery.
