It also makes recommendations to management on ways to increase safety awareness. As an ongoing commitment to a safe work environment, "Tool Box Safety" talks are part of monthly department meetings and bi-weekly safety awareness bulletins are distributed to employees.

  • What Our Customers Say:

  • "During a storm we developed a leak, we called you to repair the leak, and you visited that morning and fixed the leak. That afternoon we had another thunderstorm and the leak redeveloped. I called again that evening and you sent your technician Wink. He fixed the leak once and for all. The leak is history. Thanks for your response to my need and a special thanks to Wink. He is very professional, thorough and he explained all of what he did. That's why I use you."
