"Kelton and Bobby provided a very professional install on my new tankless water heater. They worked with me on the price and stayed late to make sure I knew what each feature did and the recommended maintenance schedules. Highly recommended!"

"SMK plumbing did a great job for me with a whole house water re-plumbing & main water line from the street. The team was efficient, professional, and polite. Job was started and completed in one day. They even moved the whole house shut off and pressure valve to a very easy to get to location."
