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…
Amazing experience with Heil. Water pouring out of the side of the house by the outdoor spigot at 7pm meant we had to turn the water off in the whole house. Scheduled online for a 7:30-3 window the following day. We called first thing asking if we could narrow the window so we could make arrangements with work, and…

Heil Plumbing has wonderful customer service and fast professional services. We needed a total replacement of the water line to our house. It was a complicated job on an older home. Work was done with minimum digging. The new work is more accessible and should last a very long time. Highly recommend this company.
