We bought an office building and hired Tim to get us compliant with Fire codes, AND to make our building safer for our employees and tenants, Tim came on time, updated extinguishers that needed updating, provided specific solutions for specific circumstances (proper extinguisher in server / IT area, for example), and other details not in our area of expertise. He has all he needs right in his truck, so no wasted time running out for parts or products. Very happy.
