What our clients are saying:

We have enlisted EOS Mechanical to assist us with meeting the requirements from the city regarding our backflow prevention device. The gentlemen who have come to our premises to do that were extremely pleasant and friendly. We deal with a lot of contractors as our school and I have to say, the individuals from EOS are the best I have seen. They were efficient, friendly, knowledgeable, polite and just lovely to deal with. They also took the time to explain what they had done and show me what they did and why. I would definitely recommend them to others and look forward to working with them in the future.
