This statement is one of the hardest to come up with because you want to cover all of what you and your company deems worthy. We as plumbers have been protecting health of people around us for over 2000 years. We have developed clean water, good sewer and have installed safe gas piping for home and commercial needs for years and years. We are not left to our own devices to just do our work any old way but we are watched over by federal, state, city and local laws to protect you and the environment. We are held to a higher standard to protect our customers and the environment. That is why we are proud to be licensed and insured.
When you hire unlicensed plumbers to do you work you are hiring people that really have no checks and balances for their work and they could care less about what they are doing. They have no one to oversee their work and they have not been schooled to do the work. They go on what they see or seen and a little more than that. How many people do you want to practice on Your home with your life and how about the lives of your family? They do not have insurance and no responsibility for no one except themselves.
We are schooled, licensed and insured to protect the customer and the environment. To promote safe work condition, safe water and conserve our resources and have continues education to make sure that we know the best methods and material available.
Remember not all materials that are available are allowed to be installed.
