Pursuing the truth.

Plumbing & HVAC

Plumbing & HVAC Forensic Engineering

Our expert mechanical and materials engineers provide forensic and failure analysis, design, and quality-inspection services on plumbing, process piping, and HVAC systems for multifamily and commercial buildings. We’ll provide you with the truth about your system, and we’ll be with you each step of the way to help resolve plumbing and HVAC failures. We’re experienced in conducting system-condition assessments, life-expectancy assessment, failure analysis and root-cause analysis (underperformance, leaks, pressure issues, etc.), as well as repipe management and quality-assurance services.

Plumbing Inspection & Design 

Our roots lie in the plumbing industry, and as uniquely credentialed materials and mechanical engineers, we’ve developed a deep expertise inspecting plumbing systems from start to finish. We identify the cause of a problem, inspect and redesign systems as necessary, and provide the most cost-effective, code-compliant and safe system.

HVAC Inspection & Design

Our team of mechanical and materials engineers provide our full range of engineering and consulting services for HVAC systems in multi-family and commercial buildings. When we are involved in the design phase, we maintain oversight and constant inspection to ensure our design is being implemented correctly.

Why choose us for your plumbing or hvac engineering needs?

When you work with us, you can trust we’ll make sure the job gets done on budget, within the timeline, and with the problem solved. We adapt to the problem at-hand while complying with current codes and procedures to ensure the best product possible. Our extensive knowledge on the subject of plumbing, along with our expertise in the field, makes us a great fit for any plumbing work that needs attention. When you’re able to fix small problems early on, you’ll save time and money in the long run.



Our Experts


Brad Capatch, P.E., Mechanical Engineer

Brad is a well-rounded mechanical engineering expert, focusing his efforts in the areas of plumbing system analysis, crane and hoist engineering, and forensics. Brad’s experience includes failure analysis, process engineering, welding engineering, corrosion engineering, product design in manufacturing, and the construction industry. Brad has also worked in research and development of heavy-lift equipment, including weld development and mechanical systems. His experience extends to forensics in the maritime (large and small diesel engines), construction defects (HVAC, plumbing, structural), crane and heavy equipment, piping systems, product defects, recreational equipment, and power industries.


Randy Kent, MS, P.E., Principal

Founder and principal of Kent Engineering, Randy Kent is a registered professional engineer with more than 32 years of experience in failure analysis and mechanical engineering forensics. His expertise has been sought in developing the industry-standard ASM Handbook series and International Fatigue Congress publications, and he has over 100 depositions, trials, and arbitrations to his name. In addition to his work at Kent Engineering, Randy is a professor of materials engineering for upper-level engineering students at the University of Washington, as well an advisor of curriculum development for Haward Technology Middle East. Randy holds a bachelor’s degree and master’s degree in metallurgical engineering, both from the University of Washington. In his free time, Randy can be found spending time with his wife, kids, and grandkids. He loves all adventures, but especially enjoys fishing, hunting, and exploring on his boat.
