Hendren Services & Code Academy

Passed on my first try thanks to Howard’s Master Plumber’s Exam Prep! Howard runs an amazing prep course. The reference binder he gives you is incredible — packed with everything you need and easy to navigate. His quick search indexes saved me tons of time so I could get through all 100 questions and pass on the first attempt. If you’re serious about passing the Master Plumber’s Exam, take Howard’s course. You won’t regret it!

Thankful I was able to get in on the backflow recertification course. The class was informative, hands on and visual. Thank you Brooke and Howard

I've had Howard on my list of best teachers since I was in school. He helped me get my EPA license. A few years after that, I was licensed master mechanical. I am now a licensed master plumber and I couldn't have done any of it without Howard Hendren. I will be back in the future to take his backflow prevention class. Thank you, Howard!!

Looking for a Master Mechanical prep course? Howard be thy name! Course very helpful on using coding books and taking the actual test.

Highly recommended!. The instructors are absolutely great and very knowledgeable. By far, it’s the best ASSE Backflow recertification contractor in the Kansas City area.
