The Canterbury-based firm worked on major projects throughout the capital for many of the major contractors and operated a workforce of up to 60 scaffolders.
The firm has been trying to find a buyer for several weeks after running into cash flow problems and debts with supplier Generation UK.
But its main lender called in administrator Begbies Traynor (Central) and all staff were told to go home.
Rival scaffolding contractor Alltask, based in Rochester, is understood to have stepped in and taken on many of the staff who lost their jobs along with several of Deverson’s jobs.
Deverson senior managers Mark Walton and Bruno Bohane have also joined Alltask.
Neil Vinnicombe and Jon Beard of Begbies Traynor (Central) LLP have been appointed administrators.
