    Had an emergency water heater leak that I caught thankfully. Austin was out to my house within the hour and quoted me a reasonable price for a replacement water heater. My water heater was 17 years old and definitely needed to be replaced. He had it installed and running before noon the next day. He also installed extra safety precautions in case there was another leak. I wish I had those on there with the older one. The new water heater works great and from the research I did is a good quality heater. They really came through in an emergency situation and Austin was fantastic. Very professional and helpful. I will definitely use them again for any plumbing or furnace issues.

    Hellgate Plumbing and Heating recently replaced our 70+ year-old furnace in our 99 year-old house. The team worked with good humor, resourcefulness, and efficiency to install our new, energy efficient furnace and central air conditioning. We would recommend Hellgate for any construction or home renovation! Betty & John Bennett

    Excellent communication and friendly professional technicians. Unfortunately they couldn’t repair my mini split for a reasonable price but that’s the fault of the manufacturer for subscribing to the planned obsolescence that this capitalistic hellscape of a society loves to subject us to so much. The HVAC team that came were courteous and methodical, would use them again👍🏼

    Hellgate very easy to communicate and coordinate with to determine scope of work, estimate, contract, and work scheduling. This include work by the Hellgate HVAC technician as a 3rd party electrician.

    Both the Hellgate technical and the electrician were on time and worked without break to complete the work. 

Upon completion the installation and the system operation were explained well by the technician. 

Paperwork supporting e-rebate had already been completed by the HVAC technician.

Very professional. High quality. I will continue to work with Hellgate on plumbing or HVAC needs.

    We were planning on going camping on Thursday, I went to the basement to get my bags and noticed the water heater was leaking out of the bottom. I called several plumbers and the only one that could fix us up was Hellgate Plumbing. Austin was at our house within an hour. He was very friendly and professional. We needed a pressure reducing valve, a new expansion tank and a new water heater. He completed the job quickly and we even got to go camping the same day! Thanks Hellgate Plumbing!

    We NOW only use Hellgate Plumbing! They are so professional, honest, and accommodating. We got an all in one boiler/water heater installed as well as a leaky shower pipe fixed.

    Abe was our service tech through all of it. Both my husband and I were working out of town and felt 1000% comfortable having him work his magic with us gone. He would call us regularly with updates and if he needed any additional info.

    Hellgate works with you to resolve your plumbing issue as quickly as possible and fits you into their schedule.

    HIGHLY RECOMMENDED!!
