Chad Knowles did an outstanding job working on our plumbing issues. Our water pressure was way too high due to problems with the pipes and valves near it. We also had him install a garbage disposal, fix some leaking faucets that had been leaking for a very long time. While installing the garbage disposal he noticed…

Erik came and diagnosed our disposal drain issue and snaked it. Erik was very personable and professional and the job was done quickly and professionally. I can't really comment on how the price compares but I feel like $560 for a snake is expensive. That being said we needed the service and Heil responded quickly…

Very professional but the price seems a bit high. We paid almost six hundred dollars for one hour of service. Ouch !! We’re seniors and wish the rate could be lower. We were somewhat shaken by the price we paid. We were sad.

My daughter and son-in-law uses their service and recommended HEIL plumbing and I will recommend your plumbing services to other people also.

Two sink shutoff valve replacements. Quality parts and triple checking for leaks. Delta Faucet flush. (Left me with a written record that the solenoid needed replacement by Delta.) Got reasonable quotes for future work, including whole house valve and water filter.
