Falcon contractors, con artists in the building industry

The company uses uns****ed workers which it collects randomly from the street. Nothing done is compliant with building regulations and every single part they have worked on is disfunctional. They cannot do plumbin tiling, plastering, basic building such as installing windows or building roof extensions. All fail compliance and are substandard. Very unprofessional, do not adhere to their own contract or timelines. Utilize bullying tactics as a means of people not to follow through with complaints. Dti and NHBRC have confirmed that they are not registered.
