Brad saved the closing on our house! We received a bad water test done incorrectly and late. Brad was very responsive and came out very quickly to retest the water and preemptively address any issues since we had less than a week. We would strongly recommend HI Stone to anyone needing well and/or water inspection needs. Thank you Brad!

I have been using Stone for years and always appreciate the honest treatment, great work, positive attitude, and sense of urgency. They earn my trust each and every time, and today’s issue is yet another example of it. We appreciate you! Thank you!!!!!

Our well went caput on a Sunday and I called, expecting to have someone call Monday morning. I got a call promptly afterwards to walk through some troubleshooting just to make sure it wasn't something we could take care of on our own. When it turned out to be a whole system failure, they sent someone out Monday morning and got everything replaced the next day. They were sure to check warranties for us and were able to help us replace both the pump and pressure tank under warranty. Everyone I spoke with including the Owner, office staff and field personnel were all kind and knowledgeable. Grateful for fast and reliable service!
- Samantha M.
Nothing short of professional. Were able to diagnose over the phone what the problem was. Came same day and replaced a bad tank for us. Back up and running in no time. Highly recommend.
