RBS Mechanical is a very unprofessional company. We hired them to put in a gas line in for commercial ovens. The job was done improperly. We found out after the job was completed that it should have been permitted, which RBS Mechanical never mentioned. We failed inspections because of leaks everywhere, wrong size pipes used and several other issues we were made aware of by the city inspector. They are not licensed plumbers to do this type of work so we had to hire someone who was to redo the entire job. RBS Mechanical lied several times to us about several things and even accused me of lying to them. When dealing with them, they were argumentative in all aspects, which makes for terrible customer service. I wouldn’t recommend them to anyone!
