In 1999, the 1-800-PLUMBER® name and phone number was secured, leading to the well-known “Our Name is Our Number!” slogan. In 2010, Mark Collins joined the 1-800-PLUMBER® brand as a franchisee and then in April 2015, they purchased the 1-800-PLUMBER® brand and created the foundation needed to grow 1-800-PLUMBER® into a household name throughout the country. Today, 1-800-PLUMBER® + Air locations can be found across the US, and our franchisees strive to make us the highest-quality brand in the industry through honesty and integrity, professionalism, and craftsmanship. Our teams achieve this by doing what they say they will, always telling the truth, training their team members to always conduct themselves in a professional manner, and only utilizing skilled craftsmen within the industry

One small plumbing issue can spiral into a major headache. A slow drain turns into a full clog. A tiny drip becomes a major leak. That’s why you need a team that doesn’t just patch problems, but fixes them for good. At PlumbingPro Austin, we combine quick response times with top-tier workmanship. Our licensed pros diagnose the problem thoroughly and make sure your plumbing is back to working like it should—without repeat issues.

Enoch Electric, Water, & Air, is an electrical, plumbing, & HVAC contracting company passionate about providing the best value and service in the industry. The company was founded by a DFW native engineer and real estate investor who became disenchanted by the lack of morality in the construction industry and decided the only way to combat it is to participate. We are professionals with over 30 years of experience that specialize in both residential and commercial electrical work. Give us a call today and allow us to earn your trust!

"We spent 14K on two new AC units for our house in 2021. We had to get the technicians out almost every year and multiples a year because something is always wrong. Some technicians were not experienced enough to diagnose the problem and wasted hours at our house. They also made careless mistakes (not connecting the draining pipe back in the attack) in Aug 2025. We had to run very loud fans for 5 days just to dry the water leak from the attic to our ceiling. The same technician was sent out in Nov 2025 and made the same mistake again. Now our ceiling is leaking again. The customer service did not even acknowledge or apologize for what we are going through. I am now worried that repeated leak may have caused permanent damage to our house. I do not recommend this company."
