    I was kept aware of when Henry was going to show up, he showed up, was pleasant and professional, quickly diagnosed the problem with my toilet, got the parts from his truck and had it fixed all within about a half hour.

    Henry was great - friendly, informed and professional. Here’s hoping the thermocouple he installed buys us a little more time on our 42 yo gas water heater. 🤞🏼

    06/04/26 I decided to do an upgrade on my kitchen faucet (it was leaking) and replace my upstairs bathroom toilet. It was running after being flushed until the handle was jiggled. I wanted the same as the one Hellgate installed last November in another bathroom, tall with oval seat. Called for an estimate, a plumber came that day, provided estimates and one week later I had both installed. Faucet and toilet are working perfectly, I am very satisfied with Hellgate Heating and plumbing. Quality employees, professional staff and responsive scheduling make this business my go too. 11/2025 My gas insert fireplace quit working. The first place I called said it would be a month and a half before they could even take their first look at it. I called Hellgate Plumbing and Heating and they made their first stop within the week. From there we decided a new fireplace was unavoidable. They made two more stops to work through the decision making, ordering and glitches. From first visit to installation it was a little less than a month. I could not be more happy with their professionalism, quality of service and my new fireplace Additionally, I called with a leaking toilet in the morning and a qualified repairman was here the same afternoon. The toilet was old and obsolete, so a new one was picked up and installed all with in a couple hours. No muss, no fuss and I have no complaints. Hellgate plumbing is my go to heating and plumbing service company.
