Red Sky: the background
Red Sky was one of the main contractors used by the Northern Ireland Housing Executive.
They had five contracts in four areas - south, east and west Belfast and Newtownabbey - to carry out repairs and provide fast response maintenance teams for a range of repairs.
The company has been working with the executive since 2004.
A BBC investigation discovered a number of executive tenants who were unhappy about the level of service.
They were not content about the standard of repairs carried out to their homes.
One woman who was compensated after Red Sky did some work on her house, said her home was wrecked by the people who were supposed to repair it.
The investigation also uncovered evidence that Housing Executive staff repeatedly raised concerns about the company's standards of work, primarily in west Belfast.
The Housing Executive said it would be putting in place the necessary arrangements to provide response maintenance services to its tenants.
"Red Sky Group has five separate contracts covering Housing Executive districts in Belfast and Newtownabbey," the Housing Executive said.
